A polishing wheel expansion assembly for a lathe

Abstract

The invention discloses a polishing wheel expansion assembly for a lathe, comprising a base and a clamping assembly arranged on the top of the base, a double-rod hydraulic cylinder is fixedly connected between the top and bottom of the inner wall of the base, and the double-rod hydraulic cylinder Both protruding ends pass through the base and extend to the outside of the base, the two protruding ends of the double-rod hydraulic cylinder and one end outside the base are fixedly connected with a fixing plate, and one side of the fixing plate is provided with an expansion assembly , The present invention relates to the technical field of lathe processing. The polishing wheel expansion assembly for the lathe can adjust the distance of the fan-shaped sand block protruding from the fixed ring within a certain range, so as to meet the grinding needs of different diameters of the workpiece and expand the use of the grinding wheel. At the same time, the fan-shaped sand block can be used The disassembly setting reduces a certain economic cost, avoids the disadvantage that the surface of the grinding wheel needs to be replaced as a whole, and also provides convenience for the subsequent polishing of the workpiece.

Description

technical field [0001] The invention relates to the technical field of lathe processing, in particular to a polishing wheel expansion assembly for a lathe. Background technique [0002] The polishing wheel is used for polishing the surface of the workpiece and the coating. The polishing wheel is divided into: polishing cloth wheel, hemp wheel, nylon wheel, wiring wheel, wind wheel, wool wheel, etc. There are many types. It is a press-fit flat wheel. It consists of A number of polishing wheels are pressed together, and the outer surface of each polishing wheel is evenly coated with a layer of polishing oil. During the polishing process, there is no need to add oil separately. It has a simple structure and is easy to use. [0003] Most of the existing polishing grinding wheels have an integrated structure. When the surface wears out, the entire grinding wheel needs to be replaced, which undoubtedly increases the economic cost. When the inner wall of the workpiece is polished,...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a polishing wheel expansion assembly for lathes, which solves the need to replace polishing wheels of different sizes when grinding the inner walls of workpieces with different diameters. The fixed position is not accurate enough, which affects the polishing accuracy of the workpiece, and the problem that the entire grinding wheel needs to be replaced when the surface of the grinding wheel is worn, resulting in economic losses
