Stainless steel tube outer diameter polishing device

Abstract

The invention provides a polishing device for the outer diameter of a stainless steel pipe and belongs to the technical field of grinding and polishing. By means of the polishing device, the problem that in the prior art, it is troublesome to replace grinding heads for different grinding materials is solved. According to the polishing device for the outer diameter of the stainless steel pipe, a check block is fixed to a sleeve; a shaft body at the front end of the check block is rotatably sleeved with a central hole of a rotating disc; limiting columns are arranged on the portions, at the two sides of the check block, on the rotating disc; the end of the sleeve is in hinge joint with the ends of a plurality of rods; the rotating disc is in hinge joint with a plurality of rods; the rods connected to the sleeve are as many as the rods connected to the rotating disc; the ends of the rods connected to the rotating disc are in hinge joint with the rods connected to the sleeve; a polishing grinding head is arranged at the end of each rod; the grinding face of each polishing grinding head faces the center of the sleeve; the sleeve is sleeved with a supporting bearing; a bevel gear is fixed to the sleeve. According to the polishing device, different grinding materials can be switched conveniently to be polished by changing the rotation direction of the sleeve, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of grinding and polishing, and relates to an outer diameter polishing device, in particular to a stainless steel tube outer diameter polishing device. Background technique [0002] Based on needs, some stainless steel tube outer diameters need to be polished to achieve a certain finish. [0003] Mechanical polishing is a polishing method that removes convex parts from the surface of the abrasive cutting material to obtain a smooth surface. Generally, oil stone strips, wool wheels, sandpaper, etc. are used as abrasives. The advantage of mechanical polishing is that the processed parts have good leveling and high brightness, and are more suitable for processing simple parts, medium and small products. During polishing, the high-speed rotating polishing wheel (circumferential speed above 20 m / s) is pressed against the workpiece, so that the abrasive rolls and micro-cuts the surface of the workpiece, so as to o...

This requires constant replacement of the runner or the abrasive on the runner, reducing efficiency

In addition, usually a certain type of runner is only suitable for grinding steel pipes with a fixed outer diameter. When the outer diameter of the steel pipe changes slightly or the runner becomes smaller due to wear, the runner needs to be replaced. This not only reduces the work efficiency, but also is not conducive to Full utilization of abrasives
