[0002] A fixture is a large category of tools for carpentry, ironwork, fitter, machinery, electronic control and some other handicrafts. It is mainly used as a tool to assist in controlling position or movement (or both). The fixture can be divided into three categories: process assembly fixtures, project test fixtures and circuit board test fixtures. The production process of the die is to process the raw materials into the die parts required by the design drawings through casting, forging, cutting and special processing, and then assemble the die parts into the mold according to the technical requirements of the design and process regulations. The whole process has a high repetitive operation rate and is suitable for repetitive stamping of the fixture.

A limiting ring plate 6 is arranged directly below the stamping plate 5, and the bottom of the limiting ring plate 6 extends into the inner wall of the frame seat 1 and is fixedly connected thereto. A ring groove 7 is arranged at the top center of the limiting ring plate 6, and a stamping mold 8 is embedded in the ring groove 7. Shaft frames 9 are symmetrically arranged on the left and right sides of the stamping mold 8. The bottom of the shaft frames 9 are fixedly connected to the limiting ring plates 6, and the top of the shaft frames 9 A rotating sleeve 10 is rotatably connected to the outer side of the rotating sleeve 10, and a spring sleeve 11 is fixedly connected to the lower part of the opposite side of the rotating sleeve 10. A rubber rod 12 is fixedly connected to the opposite end of the spring sleeve 11, and the opposite side of the rubber rod 12 is squeezed and fitted with the stamping die 8. A frosted pad 2 is provided at the bottom of the frame 1, and a number of anti-slip grooves are equidistantly provided on the outer side of the rubber rod 12. A buffer pad 13 is provided just above the stamping plate 5, and the top of the buffer pad 13 is fixedly connected to the frame 1.
