It can be divided into cutting and pressure machining according to the difference in processing methods. When cutting, machine tools are often used to process the workpiece in order to quickly and accurately process the workpiece into a suitable shape. When processing the workpiece, the machine tool needs to use a fixture to fix the position of the workpiece.

[0003] After searching, the existing patent (publication number CN 219234583 U) discloses that the utility model discloses a precision hardware milling machine fixed fixture, including a base, a fixed clamping plate is fixedly installed at one end of the top surface of the base, and a bottom limit groove is opened at the other end of the top surface of the base, and a chip removal groove is opened through the bottom surface of the bottom limit groove, a first plug-in plate is fixedly installed at the bottom of the first expansion plate, and the first plug-in plate is fitted with the inner wall of the first slot, and a second plug-in plate is fixedly installed at the bottom of the second expansion plate, and the second plug-in plate is fitted with the inner wall of the second slot, and the second slot is opened on the movable clamping plate. The precision hardware milling machine fixed fixture adopts a new structural design, which can not only avoid the debris generated during production from being released from the fixture drive mechanism, but also can discharge the debris in time, ensuring that the fixture can work stably for a long time, and at the same time, an expandable component is added, which can increase the contact area between the fixture and large-sized components, improve the fixture's fixing effect on parts of different specifications, and improve applicability.
