Clip-on spring-centering clamping cylinder body

Clip-on spring-centering clamping cylinder body    
   This centering clamping sleeve body type commonly used in the installation of the work piece.   
  Cnc machine center Elastic centering clamping simple structure, small size, easy to operate quickly, so a wide range of applications. Centering accuracy of its stability in between0.04mm~ 0.010mm. In addition to the above described centering clamping bodies, are commonly used diaphragm chuck body, corrugated centering clamping sets of institutions, as well as fluid bodies such as plastic clamping
Cnc machine center Machining fixture is an indispensable component in the machine tool technology to high-speed, high efficiency, precision, complex, intelligent, environmentally-friendly direction, driven by technology is moving fixture high-precision, high-performance, modular, mix, general economic direction.    

Cnc machine center First, high-precision  Machining with improved accuracy, in order to reduce the positioning error and improve machining accuracy of the fixture manufacturing precision demanding high-precision positioning jig Distance accuracy up to ± 5μm the bearing surface of the vertical fixture achieve 0.01mm / 300mm up to parallelism0.01mm/500mm. Switzerland duplication EROWA Flexible fixture positioning accuracy of up to 2 ~5μm. Precision machine tool fixture to the micron level has been raised the worlds leading manufacturer of fixture is precision machinery manufacturing enterprises. It is true that, in order to meet the needs of different industries and economy, folders with different models, as well as the different grades for the accuracy of the standard options.

Institutions centering clamping

Institutions centering clamping
 Precision CNC machining parts  When the work piece is processed by the central element of surface (axis, the center plane, etc.) for the base process in order to enable the base to reduce the positioning error of coincidence to be used centering clamping body.   
  Centering centering clamping body and clamping the two functions such as horizontal self-centering three-jaw lathe chuck is a classic example of the most commonly used.   
 Centering centering clamping the role of institutions according to their principle, there are two types, one is relying on the transmission mechanism so that mobile speed centering clamping device in order to achieve centering clamping, such as spiral leveraged institutions such as wedge; the other is the use of thin-walled elastic element force even after the elastic deformation (contraction or expansion), to achieve centering clamping, such as a spring clip drum, diaphragm chuck, bellows units, such as liquid plastic.
   1. Centering clamping body spiral   
   Precision CNC machining parts Rotary screw thread at both ends to the contrary, the same pitch. When it spins, the two V-shaped gag against the constant movement in order to achieve the centering of the work piece clamping or release. V-shaped work pieces of different shapes can shut up the replacement.
     Centering clamping bodies such features are: simple structure the work trip and general good but the centering accuracy is not high mainly suitable for rough or semi-finished tour of the needs of large and less demanding precision centering occasions.   
 2. Leveraged institutions centering clamping 
  Three-jaw self-centering leveraged trading cards, sleeve for axial movement the circle are three fabric hook lever will rotate around the axis, the three struck the slider along the radial movement of the cards in order to promote its claws the work piece centering and clamping or release.  
    Precision CNC machining parts  This centering clamping rigid body, and move fast, by force multiplier, and the work trip is also characterized by relatively large, but its relatively low precision centering. Generally about 0.1mm it is mainly used for rough work. Since the body can not self-locking lever, so that organizations rely on self-locking air pressure or other agencies. 
   3. Centering clamping wedge bodies  
   Wedge mobile folder automatically centering body claw when the work piece surface within the hole and left the position in the fixture after the six-cylinder through the rod so that the left claw clip due to the role of ontology on the slope while the left claw folder to the opened outside the bulge will be centering the workpiece clamping the other hand claw shifted to right folder in the role of spring circle card folder under claw to release the work piece.    

 Centering clamping bodies such compact structure usually ranging from precision centering 0.02mm~ 0.07mm compared with the hole for the workpiece surface for positioning the base of the semi-finishing processes.

Eccentric Clamp

Eccentric Clamp  
   Precision CNC machining parts With eccentric pieces, directly or indirectly, the work piece clamping body, known as the eccentric clamping body. There are two types of eccentric pieces, that is, and the curve of eccentricity eccentric circle, which, due to a round eccentric structure is simple and easy to manufacture and is widely used.  
    Precision CNC machining parts Eccentric clamping processing is easy to operate, rapid clamp, the disadvantage of clamping force and clamping trip are small. Not generally used in cutting force, Precision CNC machiningparts vibration small there is no centrifugal force of the impact of the processing.
