Description

Technical Field

[0002] Auto parts are the various units that constitute the overall auto parts processing and the products that serve the auto parts processing. Auto parts need to be fixed during the production and processing. If some special-shaped parts are encountered, the parts may shake due to the mismatch between the clamping device and the special-shaped parts, affecting the processing of the parts.

[0003] A patent with a publication number of CN203665131U is disclosed in the prior art. The solution includes a body, a clamping member, an upper clamping jaw assembly, a lower clamping jaw assembly, a positioning element and an adjusting screw. The body is provided with a U-shaped groove A in the up-down direction, and a dovetail groove is provided at the bottom of the U-shaped groove A in the up-down direction. A U-shaped opening groove is provided in the middle of the positioning element. The positioning element is installed in the middle of the U-shaped groove in the up-down direction and is connected to the body with a screw A. The adjusting screw passes through the U-shaped opening groove. The upper clamping jaw assembly and the lower clamping jaw assembly are respectively installed at the upper and lower ends of the dovetail groove and are connected with an adjusting screw. The clamping member contacts the right side of the body and is connected with a screw B. The structure is simple, the jaw spacing is adjustable, and the shaft parts with a diameter within a certain range can be clamped. The workpiece is pulled out by using the moving action of the turning center tool holder, which not only realizes the automation of workpiece clamping and stretching, but also can accurately control the length of the workpiece.

[0004] As the existing devices are used, the shortcomings of the technology are gradually exposed, mainly in the following aspects:
