Automatic welding machine for chains

Abstract

The invention discloses an automatic welding machine for chains. The automatic welding machine comprises a rack, and a location clamping system, a transmission system, a welding system and an electronic control system are arranged on the rack. The location clamping system comprises a clamping air cylinder, a first rotation rod and a second rotation rod. The first rotation rod and the second rotation rod are arranged left and right coaxially and oppositely, a clamping plate is arranged at the opposite ends of the second rotation rod and the first rotation rod respectively, coaxial location columns extending inwards are arranged on the two clamping plates respectively, and the first rotation rod is controlled by the clamping air cylinder to move laterally. The transmission system comprises a motor and a chain drive mechanism, and the first rotation rod and the second rotation rod are driven by the motor and the chain drive mechanism to rotate synchronously. The welding system comprises a welding machine, a welding gun, a welding gun support, a welding gun support moving platform and a welding air cylinder. The electronic control system comprises a sensor, a stroke controller and a counter. The automatic welding machine has the advantages of being simple and rapid to operate, low in labor intensity, high in working efficiency, safe and reliable and good in welding quality.

Description

technical field [0001] The invention relates to the technical field of chain welding, in particular to an automatic chain welding machine. Background technique [0002] In the chain industry, the connection between the chain plate and the sleeve of the bent plate chain needs to be completed by welding.

Production capacity requirements and poor economic benefits; and manual welding will inevitably inhale a large amount of gas generated during welding. Over time, it will cause great harm to the human body and pose a safety hazard
