Description

Technical Field

[0001] This utility model relates to the field of polishing device technology, specifically to a single-sided polishing machine structure with positioning function. Background Technology

[0002] In the field of precision manufacturing, surface polishing is a crucial process. The quality of the polishing process directly determines key performance indicators such as surface roughness, flatness, and surface defects of the workpiece, thereby affecting the performance, yield, and reliability of the end product. Single-sided polishing machines are the core equipment for completing this process. In practical applications, single-sided polishing machines adsorb the workpiece into a carrier above the polishing disc. However, the traditional pore adsorption method lacks an effective hard limit or sensor feedback mechanism, making it difficult to ensure that the workpiece is accurately placed at the geometric center of the polishing disc each time. The initial positioning deviation amplifies the instability during the polishing process, which urgently needs improvement. Utility Model Content

[0003] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a simple, reasonably designed, and easy-to-use single-sided polishing machine structure with positioning function. By adding a clamping structure to the outside of the carrier, the outer ring wall of the workpiece is clamped, which not only drives the workpiece to be centered and placed at the bottom of the carrier, but also strengthens the stability of the workpiece.

A support platform is sleeved on the carrier, and the lower surface of the support platform is flush with the lower surface of the carrier; a support ring is fixedly installed on the upper side of the support platform, and the outer ring wall of the support ring and the outer ring wall of the support platform are located on the same outer ring wall. The clamping frame consists of several clamping frames, which are distributed circumferentially and diagonally on the lower side of the support platform. The clamping frame is arranged in an inverted "L" shape, and the horizontal end of the clamping frame is in contact with the bottom of the support platform. A drive assembly is disposed on the upper side of the carrier; The above technical solution design adds a support platform to the outside of the carrier and drives the clamping frame to clamp the side wall of the workpiece.

[0005] As a further improvement of this utility model, the driving component includes: A rotating gear is screwed onto the outside of the connecting platform via a bearing; The number of transmission gears is the same as that of the clamping frame, and they are arranged in a circumferentially angularly meshing configuration on the outside of the rotating gear.
