Description

Technical Field

[0002] Stamping is a plastic processing technology that uses the pressure of a die to deform sheet metal, thereby obtaining parts with certain shapes, sizes and properties. The parts obtained after stamping are called stamping parts. During the inspection process, stamping parts are clamped and fixed by a fixture to facilitate inspection by instruments or measuring tools.

[0003] Application No. 202323581574.6 discloses a stamping part inspection fixture, including a base plate and two sets of vertical plates. A clamping mechanism is provided on the vertical plates, comprising a horizontal column and a bearing. A side plate is fixedly mounted on one end of the horizontal column, and a mounting ring is fixedly mounted on the inner wall of the bearing. One end of the horizontal column passes through the interior of the mounting ring, and an upper screw hole is opened inside the mounting ring.
