Abstract

The invention discloses an electrode protection box for a welding arm and electrode arm of a resistance welding robot. The electrode protection box solves the technical problems that as mentioned in abackground technology, the diameter of the electrode arm of the electrode protection box in the prior art is small, the strength is low, and an O-type ring is easy to damage. According to the technical scheme, the electrode protection box for the welding arm and electrode arm of the resistance welding robot comprises an electrode protection box body; a groove is concavely formed in the end surface of one end of the electrode protection box body; a water inlet channel and a water outlet channel are formed in the electrode protection box body; and a water inlet joint and a water outlet joint are arranged at an inlet and outlet of the outer surface of the electrode protection box body correspondingly. The electrode protection box has the advantages that the diameter of the electrode arm of the resistance welding robot can be made to be larger, the strength is increased, the damage to the O-type ring in installation processes is prevented, left and right universality is realized, parts are much shorter than before, and materials and the machining cost are saved.

Description

technical field [0001] The invention relates to an electrode protection box used on a welding arm and an electrode arm of a resistance welding robot. Background technique [0002] The protection box is used in the resistance welding robot welding torch. Resistance welding uses a transformer to reduce the voltage and increase the current to increase the instantaneous short-circuit current, and use the instantaneous heat to melt the plates to be welded, thereby bonding them together , due to the need for a large current, the conductivity between the conductor loops needs to be high, and copper was generally used before. After welding, the electrode arm part needs to be cooled rapidly. If the cooling is not good, the electrode will be hot, the electrode is easily deformed, and the wear is fast. The front end electrode arm of the resistance welding robot will be cooled by water when space permits. Reduce loss. [0003] Due to the high efficiency requirements of resistance weld...
