How much do you know about the basic knowledge of precision parts processing fixtures

Precision parts processing fixture refers to the device installed on the machine tool to clamp the workpiece or guide the tool so that the workpiece and the tool have the correct mutual positional relationship. According to its role and function, CNC machine tool fixtures are usually composed of positioning components, clamping devices, installation and connection components, and fixtures.

The positioning element is one of the main positioning elements of the fixture, and its positioning accuracy will directly affect the processing accuracy of the workpiece. Commonly used positioning elements include V-shaped blocks, positioning pins, positioning blocks and so on.

The function of the clamping device is to maintain the positioning position of the workpiece in the fixing device, so that the workpiece will not change its original position due to external forces during processing.

The coupling element is used to determine the position of the fixture on the machine tool, so as to ensure the correct machining position between the workpiece and the machine tool.

Precision parts processing also have certain requirements for its fixtures, which are: accuracy and rigidity requirements, positioning requirements, openness requirements, fast clamping requirements, and easy chip removal.

The fixture is the basic part of the fixture, which is used to connect various components or equipment on the fixture to make it into a whole to ensure the accuracy and rigidity of the workpiece.
