A kind of internal and external polishing equipment for automobile air-conditioning copper pipe

Abstract

The invention belongs to the field of mechanical processing equipment, in particular to a kind of internal and external polishing equipment for automotive air-conditioning copper pipes. When polishing the existing air-conditioning copper pipes, the inner and outer surfaces of the air-conditioning copper pipes must be polished sequentially, so the polishing efficiency is low and the polishing speed is slow. problem, the following scheme is proposed, which includes a working board, the top four corners of the working board are welded with side plates, the tops of the four side plates are welded with the same top plate, the top of the working board is welded with a fixed plate, and the fixed plate A driven hole is opened, and a driven shaft is installed in rotation in the driven hole, a driving motor is fixedly connected to the top of the top plate, a driving shaft is welded on the output shaft of the driving motor, and the outer sides of the driving shaft and the driven shaft are fixedly sleeved respectively. The first sprocket and the second sprocket have the same chain meshed with the outside of the first sprocket and the second sprocket. The invention can simultaneously polish the outer surface and the inner surface of the copper tube, and has high polishing efficiency and fast polishing speed.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to an equipment for polishing the inside and outside of copper pipes of automobile air conditioners. Background technique [0002] With the reduction of the cost of automobiles, automobiles have entered most families, and family automobiles have become the main means of transportation for commuting to work or traveling during holidays. Due to the frequent use of automobiles, people have put forward higher requirements for the comfort of automobiles. Therefore, in order to make drivers and passengers more comfortable in terms of temperature perception, car air conditioners have become a common tool for people, and with the frequent use of car air conditioners, car air conditioner copper pipes have also become one of the consumables of car air conditioners. [0003] The inner and outer surfaces of the air-conditioning copper pipes of automobiles need to be poli...
