Polishing grinding wheel expansion assembly for lathe

Abstract

The invention discloses a polishing grinding wheel expansion assembly for a lathe, and relates to the technical field of lathe machining. The polishing grinding wheel expansion assembly comprises a base and a clamping assembly arranged at the top of the base, wherein a double-rod hydraulic cylinder is fixedly connected between the top and the bottom of the inner wall of the base; and the two extending ends of the double-rod hydraulic cylinder penetrate through the base and extend out of the base, fixing plates are fixedly connected to the ends, located outside the base, of the two extending ends of the double-rod hydraulic cylinder, and an expansion assembly is arranged on one side of each fixing plate. According to the polishing grinding wheel expansion assembly for the lathe, the distance of fan-shaped grinding blocks extending out of fixing rings can be adjusted within a certain range, so that the grinding requirements of workpieces with different diameters are met, and the use range of a grinding wheel is expanded; and meanwhile, the fan-shaped grinding blocks are detachably arranged, so that certain economic cost is reduced, the defect that the whole grinding wheel needs to bereplaced when the surface of the grinding wheel is abraded is overcome, and convenience is also provided for subsequent workpiece polishing work.

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,...

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
