Embodiment Construction

[0031] see figure 1 , the polishing device of the inner wall of the tubular workpiece includes a frame, a cylinder 3 and a crank rocker mechanism in this example;

[0032] see Figure 1~3 , the frame is composed of a rectangular base 1 and a swing frame 2 arranged on the base 1, and a pillar 1-1 perpendicular to the upper surface of the base 1 is respectively provided on both sides of the base 1. The swing frame 2 is polygonal, and the middle part of the two sides of the polygon is vertically provided with a trunnion 2-1. 1 to form a hole shaft fit, the rotation center line of the trunnion 2-1 is parallel to the horizontal plane.

[0033] see Figure 4 , the middle part of the drum 3 is cylindrical, and the two ends are radially contracted to form a truncated cone with pointed ends facing outwards. The cylindrical middle part of the cylinder 3 is used for coaxial clamping of the tubular workpiece 9 to be processed. A clamping opening 3-5 for clamping workpieces is formed ...

Abstract

The invention discloses a polishing device for the inner wall of a tubular workpiece. The polishing device comprises a rack, a drum and a crank and rocker mechanism, wherein the rack is composed of a base and a swinging and rotating frame arranged on the base, and the middle portions of the two sides of the swinging and rotating frame are horizontally supported by two supporting columns extending from the base through lugs; a tubular workpiece clamping opening is formed in the side wall of the drum, and the outer side of the clamping opening is provided with an arc pressing cover which covers the clamping opening; a charging opening with a sealing cap is arranged at one end of the drum; the two ends of the drum are supported by the two ends of the swinging and rotating frame through other lugs, and one end of one of the lugs is connected with an output shaft of a first motor arranged outside the swinging and rotating frame. The crank and rocker mechanism is formed by sequentially hinging a crank, a connecting rod and a rocker, wherein the free end of the crank is fixedly connected with an output shaft of a second motor arranged on the base, and the free end of the rocker is fixedly connected with the corresponding lug. The polishing device provided by the invention has the advantages that polishing is uniform, and the structure is simple.

Description

technical field [0001] The invention relates to a polishing device, in particular to a polishing device for the inner wall of a long workpiece with a uniform section in a main direction. Background technique [0002] Polishing refers to a processing method that does not cut or removes a very thin layer of material from the workpiece to reduce the surface roughness of the workpiece. In the machinery manufacturing industry, many parts need to be polished to obtain a suitable roughness according to their use requirements. [0003] There are many polishing methods in the prior art, such as smooth grinding, sand blasting, shot blasting, jet polishing and abrasive flow processing. Different processing methods have their own characteristics, and the staff will choose the appropriate polishing method according to the needs when polishing different workpieces. [0004] The polishing process of the inner wall of the tubular workpiece has always been a difficult problem in the machin...
