A ring welding opening and closing machine that automatically tracks the welding position

Abstract

The invention belongs to the technical field of special machining devices, and provides a special circumference weld opening / closing machine capable of tracking the welding position automatically. A middle opening / closing box body with an upper box body and a lower box body is mainly adopted for the circumference weld opening / closing machine. An air cylinder supporting base fixed to the lower box body is connected with the lower end of an air cylinder through a pin shaft. An air cylinder connection block is directly connected with a piston rod of the air cylinder and connected with the upper box body through a connection pin shaft. The upper box body is connected with the lower box body through an opening / closing shaft. The upper box body is provided with an adjustment shaft, a blocking shaft and a side jacking shaft. The lower box body is provided with a correction block, a small opening stopping block and an opening / closing gear supported by a supporting wheel, and the two sides of the lower box body is provided with a blocking shaft and a side jacking shaft respectively. A small gear in the middle opening / closing box is meshed with the opening / closing gear through an intermediate gear. According to the circumference weld opening / closing machine, the middle opening / closing box body is designed to be of an opening / closing structure, the part taking process is reduced for operators, the operators can directly take out products from the front, meanwhile the scratching and collision rate of the products is lowered, and working efficiency and product quality are improved.

Description

technical field [0001] The invention relates to a special opening and closing machine for ring welding that automatically tracks welding positions, and belongs to the technical field of special equipment for machining. Background technique [0002] At present, when the horizontal welding special machine for welding automobile exhaust system in China is welding muffler or carrier assembly products, since the middle opening and closing box supporting the product mechanism is a closed large gear, the operator needs to open and close the box from the middle to pick up the parts. Taking out from one side requires at least 3 steps to complete the task of picking up the piece, and it is not suitable for operation. It is easy to scratch the appearance of the product when picking up the piece, making it difficult for the operator to pick up the piece. The middle opening and closing box structure is designed as an opening and closing structure, which greatly reduces the operator's pic...
