Semi-automatic spot welding machine

Abstract

The invention discloses a semi-automatic spot welding machine. The semi-automatic spot welding machine comprises a control cabinet and a work platform. A controller, a welding host and a cleaning host are arranged in the control cabinet, and the controller is used for controlling the welding host and the cleaning host to work. The welding host is connected with a movable weld gun and a fixed weld gun. The work platform is provided with a bonding pad capable of rotating. A body of the fixed weld gun is fixedly arranged below the bonding pad, a gun head stretches out of the bonding pad, and the gun head can be adjusted in the up-down direction, the front-back direction and the left-right direction. A positioning needle is arranged on the work platform and used for limiting the welding range. The cleaning host is connected with a cleaning gun and used for cleaning welding spots. A pedal switch is arranged at the bottom of the work platform and is capable of controlling the welding host to start or stop working. The work of the spot welding machine is controlled through the pedal switch, the welding speed is increased, and the welding efficiency is improved. In cooperation with a control function of the controller, people with or without welding experience can rapidly know how to operate the semi-automatic spot welding machine, meanwhile, the cleaning function is achieved, and the welding effect can be improved.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to a semi-automatic spot welding machine. Background technique [0002] The argon arc welding spot welding technology is: using argon gas as the shielding gas, tungsten electrode as the non-melting electrode, with the help of the arc generated between the tungsten electrode and the weldment, the joint between the weldment and the weldment, individual points on the contact surface, welding technique. [0003] Existing argon arc welding spot welding machines usually have high requirements for the experience of operators, the degree of machine automation is low, and the function is single. If the operator does not have certain welding experience, it is easy to cause problems such as low welding efficiency and low yield. Contents of the invention [0004] In view of this, the purpose of the present invention is to overcome the deficiencies of the prior art and provide a sem...
