Description

Technical Field

[0001] This utility model belongs to the technical field of grinding and polishing equipment, and in particular relates to a pressure mechanism for a power-driven hook-type polishing head. Background Technology

[0002] For the polishing head device in the polishing equipment, it is necessary to apply pressure to it to increase the pressure between the workpiece and the lower grinding disc and the upper polishing head, thereby increasing the friction and improving the processing effect. For vertically arranged polishing head devices, the pressure mechanism can be integrated into the polishing head device.

[0003] As for the power hook-type slingshot, due to its special position and structure, it is impossible to integrate the pressurization mechanism into one unit, which is not conducive to the design and layout of the pressurization mechanism. Similarly, as the workpiece specifications or the pressurization point change, it also needs to have a certain degree of adjustability.

[0004] Therefore, designing an adjustable, simple, and adaptable pressurization mechanism for power hook-type throwing heads is a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this utility model is to provide a pressurizing mechanism for a power hook-type throwing head. The connection between the ejector pin and the cylinder and the machine body is achieved through the swing arm and the column, so that the cylinder can rotate at a certain angle following the swing arm. Through the design of the opening groove and the waist-shaped opening of the sliding sleeve, the distance between the cylinder and the column can be adjusted, thereby achieving a wide range of adjustment, so that the pressurizing point is within the adjustable range, thus improving the applicability.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
