Manual operation of a simulation of the automatic machinery, ,Precision CNC machining parts it can be a fixed program draws ﹑ handling objects or perform household tools to accomplish certain specific actions. Application of robot can replace the people engaged in monotonous ﹑ repetitive or heavy manual labor, the mechanization and automation of production, instead of people in hazardous environments manual operation, improving working conditions and ensure personal safety. The late 20th century, 40, the United States atomic energy experiments, the first use of radioactive material handling robot, human robot in a safe room to manipulate various operations and experimentation. 50 years later, manipulator and gradually extended to industrial production sector, for the temperatures, polluted areas, and loading and unloading to take place the work piece material, but also as an auxiliary device in automatic machine tools, machine tools, automatic production lines and processing center applications, the completion of the upper and lower material, or From the library take place knife knife and so on according to fixed procedures for the replacement operation. Robot body mainly by the hand and sports institutions. Agencies with the use of hands and operation of objects of different occasions, often there are clamping ﹑ support and adsorption type of care. Movement organs are generally hydraulic pneumatic ﹑ electrical device drivers.

  Precision CNC machining parts  Manipulator can be achieved independently retractable ﹑ rotation and lifting movements, generally 2 to 3 degrees of freedom. Robots are widely used in metallurgical industry, machinery manufacture, light industry and atomic energy sectors.

 ,Precision CNC machining parts Can mimic some of the staff and arm motor function, a fixed procedure for the capture, handling objects or operating tools, automatic operation device. It can replace human labor in order to achieve the production of heavy mechanization and automation that can operate in hazardous environments to protect the personal safety, which is widely used in machinery manufacturing, metallurgy, electronics, light industry and nuclear power sectors.

  Mechanical hand tools or other equipment commonly used for additional devices, such as the automatic machines or automatic production line handling and transmission of the workpiece, the replacement of cuttingtools in machining centers, etc. generally do not have a separate control device. Some operating devices require direct manipulation by humans; such as the atomic energy sector performs household hazardous materials used in the master-slave manipulator is also often referred to as mechanical hand. 

 Precision CNC machining partsManipulator mainly by hand and sports institutions. Task of hand is holding the workpiece (or tool) components, according to grasping objects by shape, size, weight, material and operational requirements of a variety of structural forms, such as clamp type, type and  adsorption-based care such as holding. Sports organizations, so that the completion of a variety of hand rotation (swing), mobile or compound movements to achieve the required action, to change the location of objects by grasping and posture.

Mechanical hand classification and characteristics

  Mechanical hand classification and characteristics

 Robots are generally divided into three categories:

 Precision CNC machining parts The  first is the general machinery does not require manual hand. It is an independent not affiliated with a particular host device.

 It can be programmed according to the needs of the task to complete the operation of the provisions. It is characterized with ordinary mechanical performance, also has general machinery, memory, intelligence ternary machinery.

  Precision CNC machining partsThe second category is the need to manually do it, called the operation of aircraft. It originated in the atom, military industry, first through the operation of machines to complete a particular job, and later developed to operate using radio signals to carry out detecting machines such as the Moon. Used in industrial manipulator also fall into this category.

   Precision CNC machining partsThe third category is dedicated manipulator, the main subsidiary of the automatic machines or automatic lines, to solve the machine up and down the work piece material and delivery. This mechanical hand in foreign countries known as the "Mechanical Hand", which is the host of services, from the host-driven; exception of a few outside the working procedures are generally fixed, and therefore special

  

The composition

The composition

  Precision CNC machining parts  the composition, mechanical hand Robot in the form of a variety of forms, some relatively simple, some more complicated, but the basic form is the same as the composition of the , Usually by the implementing agencies, transmission systems, control systems and auxiliary devices composed.

 1. Implementing agencies Manipulator executing agency by the hands, wrists, arms, pillars. Hands are crawling institutions, Precision CNC machining parts is used to clamp and release the workpiece, and similar to human fingers, to complete the staffing of similar actions. Wrist and fingers and the arm connecting the components can be up and down, left, and rotary movement. A simple mechanical hand can not wrist. Pillars used to support the arm can also be made mobile as needed.

2. Transmission The actuator to be achieved by the transmission system. Sub-transmission system commonly used manipulator mechanical transmission, hydraulic transmission, pneumatic and electric power transmission and other drive several forms

 3. Precision CNC machining parts Control System Manipulator control system's main role is to control the robot according to certain procedures, direction, position, speed of action, a simple mechanical hand is generally not set up a dedicated control system, using only trip switches, relays, control valves and circuits can be achieved dynamic drive system control, so that implementing agencies according to the requirements of action. Action will have to use complex programmable robot controller, the micro-computer control.

There are also places where it fly in the ointment:  

 1. As the compressibility of air, resulting in poor aerodynamic stability of the work, resulting in the implementing agencies as the precision of the velocity and not easily controlled.

 2. As the use of low atmospheric pressure, the output power can not be too large; in order to increase the output power is bound to the structure of the entire pneumatic system size increased.

Precision CNC machining parts With pneumatic drive and compare with other energy sources drive has the following advantages: Air inexhaustible, used later discharged into the atmosphere, without recycling and disposal, do not pollute the environment. Accidental or a small amount of leakage would not be a serious impact on production.

Precision CNC machining parts Viscosity of air is small, the pipeline pressure loss also is very small, easy long-distance transport. The lower working pressure of compressed air, pneumatic components and therefore the material and manufacturing accuracy requirements can be lowered. In general, reciprocating thrust in 1 to 2 tons pneumatic economy is better.Compared with the hydraulic transmission, and its faster action and reaction, which is one of the outstanding merits of pneumatic.

Precision CNC machining parts Clean air medium, it will not degenerate, not easy to plug the pipeline. It can be safely used in flammable, explosive and the dust big occasions. Also easy to realize automatic overload protection.

Skids the guide screw and the ball bearing guide screw     

 The CNC machining parts  guide screw transmission relates directly to the transmission chain precision. The guide screw selects mainly is decided requests and drives the torque request in the job precision. Is  not used by job precision request Gao Shike skids the guide screw, but should inspect the original guide screw attrition situation, like the pitch error and the pitch accumulative error as well as matches the nut gap. The ordinary circumstances skid the guide screw to be supposed not to be lower than 6 levels, the nut gap oversized then replaces the nut. Uses skids the guide screw relative ball bearing guide screw price to be  low, but satisfies the precision high components processing with difficulty

 The ball bearing guide screw rubs loses slightly, the efficiency is high, CNC machining parts  its transmission efficiency may above 90%; Precision high, the life is long; When start moment of force and movement the moment of force approaches, may reduce the electrical machinery to start the moment of force. Therefore may satisfiedly compare the high accuracy components processing request

 Safe protection

  The effect must take the security as a premise. Transforms in the engine bed must take the corresponding measure according to the actual situation, cuts noticeable. CNC machining parts  The ball bearing guide screw vice- is the precision part, when the work must take strict precautions against the dust is specially the scrap and the hard sand grains enters the roller conveyer. On longitudinal guide screw also coca overall sheet iron safety mask. The big carriage with skids two end surfaces whichCNC machining parts  the guide rail contacts to have to seal, prevented absolutely the flinty granulated foreign matter enters the sliding surface damage guide rail

Internal stresses

Precision CNC machining parts Cold forming is done above the yield point in the work-hardening range, so internal stresses can be built up easily. Evidence of this is the springback as the work leaves the forming operation and the warpage in any subsequent heat treatment. Even a simple washer might, by virtue of the internal stresses resulting from punching and then flattening, warp severely during heat treating.  believed in the virtue of prayer.

 Precision CNC machining parts  When doubt exists as to whether internal stresses will cause warpage, a piece can be checked by heating it to about 1100 and then letting it cool. If there are internal stresses, the piece is likely to deform. Pieces that will warp severely while being heated have been seen, yet the heat-treater was expected to put them through and bring them out better than they were in the first place

 Welding

 The maximum carbon content of plain carbon steel safe for welding without preheating or subsequent heat treatment is 0.3%. higher-carbon steel is welded every day, but only with proper preheating. There are two important factors: the amount of heats that is put in  the rate at which it is removed

 Precision CNC machining parts  Welding at a slower rate puts in more heat and heats a large volume of metal, so the cooling rate due to loss of heat to the base metal is decreased. A preheat will do the same thing. For example, sae4150 steel, preheated to 600 or 800, can be welded readily. When the flame or arc is taken away from the weld, the cooling rate is not so great, owing to the higher temperature of the surrounding metal and slower cooling results. Even the most rapid air-hardening steels are weldable if preheated and welded at a slow rate.
