Cross joint pipe inner side wall polishing device

Abstract

The invention relates to a cross joint pipe inner side wall polishing device. The cross joint pipe inner side wall polishing device comprises a base and a mounting frame. A rotary plate is slidably mounted on the mounting frame, a positioning pin is disposed on the lower portion in front of the rotary plate, and the positioning pin is connected with an air cylinder; two C-shaped clamping openings are formed in the front end face of the rotary plate, and fastening bolts are mounted at the front ends of the clamping openings; four outwards extending plates are uniformly distributed on the circular arc end face of the rotary plate, a clamping seat is slidably mounted on the base, and the clamping seat is connected with a spring; a polishing driving assembly is disposed above the rotary plate and comprises a polisher, the position of the polisher is matched with that of the positioning pin, and a back frame for fixedly mounting the polishing driving assembly is disposed in rear of the polishing driving assembly. By means of the cross joint pipe inner side wall polishing device, the polisher can be controlled to automatically polish the single inner side pipe wall of a cross joint pipe, positioning shifting can be achieved by controlling the rotary plate to rotate by 90 degrees, and the polishing efficiency is improved.

Description

technical field

[0001] The invention relates to a mechanical processing device, in particular to a grinding device for the inner side wall of a cross connecting pipe. Background technique

[0002] Generally speaking, cross connection pipes are generally used for cross-type ground water pipe connections. After finishing the finishing of the cross connecting pipe, it is often necessary to grind the inner pipe wall of the cross connecting pipe. Whether it is the choice of fixture or the choice of processing method is a difficult problem. Contents of the invention

[0003] Aiming at the above-mentioned problem that grinding the four inner side walls of the cross connecting pipe is difficult, the present invention proposes a grinding device for the inner side wall of the cross connecting pipe.

[0004] A grinding device for the inner side wall of a cross connecting pipe mainly includes a base and a mounting frame on the base. The front end of the mounting frame is slidably mo...
