Taper pipe inner wall grinding method

Abstract

The invention discloses a taper pipe inner wall grinding method. The method involves a bottom frame, a supporting seat, an axial driving device, a screw rod and a nut, wherein the supporting seat is fixed at one end of the bottom frame, two supporting assemblies are arranged on the bottom frame side by side and used for supporting the taper pipe, the axial driving device is arranged on one side of the supporting seat, one end of the screw rod is fixed to the other side of the supporting seat, a thread lead angle of the screw rod is larger than a thread self-locking angle, a nut is connected to the screw rod in a threaded mode and sleeved with a rotating shaft, three inner wall grinding devices are arranged on the outer wall of the rotating shaft in the circumferential direction at intervals, the axial driving device is used for driving the nut to move in the axial direction, each of the inner wall grinding device comprises a grinding assembly and two three-stage spring telescopic pieces, the two three-stage spring telescopic pieces are fixed to the rotating shaft side by side, and the grinding assembly is connected with the free ends of the two three-stage spring telescopic pieces. According to the taper pipe inner wall grinding method, mechanical polishing operation can be achieved, grinding efficiency is improved, and labor intensity is relieved.

Description

Technical field[0001]The present invention relates to the field of polishing equipment, and more particularly to a cone-tube inner wall grinding method.Background technique[0002]The taper tube is formed by a pipeline of different pipe diameters, and the solder tumor, welding and rust, etc. generated during the two different pipe diameters, and the inner wall surface of the taper tube is relatively rough. For these problems, it is often grinding the inner wall of the pipeline, which is low in polishing, and the labor intensity is low.Inventive content[0003]It is an object of the present invention to overcome the disadvantages described above, providing a tapered interior wall grinding method.[0004]In order to achieve the above object, the specific embodiments of the present invention are as follows:[0005]A taper tube inner wall grinding method comprising a chassis, a support, a axial drive, a screw, and a nut, the support seat is fixed to one end of the chassis, and there are two sup...

AI Technical Summary

Problems solved by technology

[0002] The tapered pipe is spliced ​​by pipes of different diameters, and there will be defects such as weld bumps, welding slag and rust spots during welding at the joint of two pipes with different diameters, and the inner wall surface of the tapered pipe is relatively rough. To solve these problems, the inner wall of the pipeline is often polished manually with hand-held grinding tools. This method has low grinding efficiency and high labor intensity.
