Polishing device based on pipe part connection mouth

Abstract

The invention relates to the technical field of motorbike frame machining, in particular to a polishing device based on a pipe part connection mouth. The polishing device comprises a rack, the rack isrotatably provided with a transmission rod, the transmission rod is provided with stretching and contracting support sets, the stretching and contracting support sets comprise connection rods in thesame plane and two supporting rods, the two supporting rods are hinged to the transmission rod, the connection rods are hinged to the free ends of the two supporting rods, the free ends of the supporting rods are both fixedly connected with balancing weight blocks, and the connection rods are fixedly connected with scraping cutters used for polishing the inner walls of pipe parts. By means of thepolishing device based on the pipe part connection mouth, occurrence of the situation that corners from the pipe mouth inner walls to the pipe body inner walls cannot be polished is avoided in performing polishing on the pipe mouth inner walls and the pipe body inner walls of the pipe parts with the pipe mouth caliber being small and the pipe body inner diameter being large.

Description

technical field [0001] The invention relates to the technical field of vehicle frame processing, in particular to a grinding device based on a connecting port of a pipe fitting. Background technique [0002] When producing motorcycle battery pack brackets, it is usually necessary to weld steel pipes to steel pipes. When welding steel pipes, if the nozzle of the steel pipe or the inner wall of the nozzle is not smooth, it will take a long time to weld the frame, and the frame will also be damaged after welding. It is prone to breakage and other situations, and it is extremely unsafe to use. [0003] Now in the factory, workers usually hold the grinding block to grind the inner wall of the nozzle, but this manual method is usually time-consuming and has low work efficiency. However, the nozzle diameter of this type of pipe fittings is usually relatively small, and it is difficult to penetrate the grinding block. When the inner wall needs to be polished, it is difficult to ach...

[0002] When producing motorcycle battery pack brackets, it is usually necessary to weld steel pipes to steel pipes. When welding steel pipes, if the nozzle of the steel pipe or the inner wall of the nozzle is not smooth, it will take a long time to weld the frame, and the frame will also be damaged after welding. It is prone to breakage, etc., and it is extremely unsafe to use

[0003] Now in the factory, workers usually hold the grinding block to grind the inner wall of the nozzle, but this manual method is usually time-consuming and low in work efficiency

However, the nozzle diameter of this type of pipe fittings is usually relatively small, and it is difficult to penetrate the grinding block. When the inner wall needs to be polished, it is difficult to achieve, the grinding effect is not good, and the grinding is not in place, which brings great inconvenience to production and processing.
