Shenzhen precision parts machining fixture is installed on the machine tool, used to clamp the workpiece or guide the tool, so that the workpiece and the tool have the correct mutual position of the relationship between the device. According to its role and function, CNC machine tool fixtures are usually composed of positioning components, clamping devices, mounting and connecting components and clamps.
The positioning element is one of the main positioning elements of the fixture, and its positioning accuracy will directly affect the machining accuracy of the workpiece. Commonly used positioning elements include V-block, positioning pin, positioning block, etc.
The function of the clamping device is to maintain the positioning position of the workpiece in the fixture so that the workpiece will not change its original position during machining due to external forces.
Coupling elements are used to determine the position of the fixture on the machine tool, so as to ensure the correct processing position between the workpiece and the machine tool.
Shenzhen precision parts processing also has certain requirements for its fixtures are: accuracy and rigidity requirements, positioning requirements, openness requirements, fast clamping requirements, easy chip removal.
Fixture is the basic part of the fixture, used to connect the various components or equipment on the fixture, so that it becomes a whole, to ensure the accuracy and rigidity of the workpiece.
