Power plant The source of clamping force
In the machining process the work piece by the cutting force, Cnc machining centrifugal force, inertia force, such as the role of, in order to ensure that these external force, the workpiece can remain in the fixture by the positioning of the processing to determine the location of components, and should be no vibration or displacement, fixture structure should be set up reliable work piece clamping device folder will be in prison. First, the composition of clamping devices
Many different types of clamping devices, but their structures are composed of two parts.
1. Power plant The source of clamping force, one human; second is generated by a power device.The device can generate power as the power unit fixture.Cnc machining Commonly used in power plant are: pneumatic devices hydraulic devices electrical devices electromagnetic devices gas - liquid interaction devices and vacuum devices. Fixture as a result of manual clamping force from the human so it does not power plants.
2. Clamping part
Receive and impart into the original clamping force to clamp the task force and part of the implementation of the general composition of the following agencies:
1) to accept the original force of bodies. Such as handles nuts and used to connect the institutions such as cylinder piston rod.
2) Force the middle of delivery. Such as hinges levers and so on.
3) Clamping components. Such as plate such as screws.
Force delivery of them in the middle of the original Cnc machining transmission of force to the process of clamping devices can play such as changes in the direction of force to change the size of forces as well as the role of self-locking and so on.
