Electric welding device

Abstract

The invention discloses an electric welding device comprising a power supply department and a gun seat; the right end surface of the power supply department is internally provided with a cavity and a longitudinal groove which downwards extends; the cavity is internally provided with a power supply device; a locking groove is formed in the right end surface of the power supply device; a first sliding groove is formed in the power supply device at the left side of the locking groove; a first cavity is arranged in the power supply device at the left side of the first sliding groove; the power supply device located below the first sliding groove is internally provided with a second cavity of which the left side end passes through the bottom of the first cavity; metal spring rods are fixedly arranged on the inner wall of the left side of the locking groove in a vertically corresponding way; the first sliding groove is internally provided with a power supply pushing part; and an extension part at the right side of the power supply pushing part extends into the locking groove. The electric welding device is simple in structure and convenient to operate; and when the gun seat is inserted, driving and locking connection is automatically controlled, and meanwhile, automatic power supply connection is completed, so that the work efficiency is increased and the safety is improved.

Description

technical field [0001] The invention relates to the technical field of welding, in particular to an electric welding device. Background technique [0002] At present, electric welding machines are used more and more widely, and they can work normally only by locking and connecting electricity. Therefore, whether the electric welding machine is firmly locked is the basis for determining whether the electric welding machine can work normally. However, the existing electric welding machine locking structure There is no self-locking structure to ensure that it will not loosen, which has great disadvantages and cannot meet the existing needs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an electric welding device, which can solve the above-mentioned problems in the prior art. [0004] The present invention is achieved through the following technical solutions: An electric welding device of the present invention in...
