Improved welding device

Abstract

An improved welding device comprises a power distribution base fixedly installed in a power distribution cabinet, a power connection terminal matched with the power distribution base, and a protectingdevice for protecting the power connection terminal. A sliding-connection cavity with an opening facing leftwards is formed in the power distribution base. An insertion-in groove is formed in the right end wall of the sliding-connection cavity. The right end of the power connection terminal is fixedly provided with a plug matched with the insertion-in groove. The protecting device comprises a sliding-connection rack in sliding-connection fit with the sliding-connection cavity, and straight plates symmetrically installed at the right end of the sliding-connection rack in an up-down mode. The left end of the sliding-connection rack is fixedly provided with a housing. Guide-connection grooves matched with the straight plates are symmetrically formed in the right end wall of the sliding-connection cavity in an up-down mode. Locking grooves are symmetrically formed in the upper end wall and the lower end wall of the sliding-connection cavity. First sliding-connection grooves are symmetrically formed in the sliding-connection rack in an up-down mode and arranged in an extending mode. The first sliding-connection grooves are provided with lock rods in a sliding-connection mode, and the lock rods are matched with the locking grooves. The housing is provided with a locking device for driving the lock rods to be matched with the locking grooves, and an unlocking device for releasing matching between the lock rods and the locking grooves.

Description

Technical field [0001] The present invention relates to the technical field of welding, in particular to an improved welding device. Background technique [0002] With the continuous maturity of welding technology, the use of electric welding machines has become more and more widely used. In some welding factories, it is necessary to move positions frequently during welding to meet the welding needs of different directions. However, the power supply of existing welding machines The plug-in connector setting mode is too simple, which makes the tightness after plug-in not high, and it is very easy to be dragged, pulled and other external factors to make the plug-in connector loose, resulting in poor contact and unable to supply power for electric welding normally, which has major drawbacks. , The existing welding machine has a poor protection capability for the plug connector. Excessive force or repeated plugging during the plugging process may cause the pin to bend and deform, sho...

[0002] With the continuous maturity of welding technology, the use of electric welding machines is becoming more and more extensive. In some welding factories, it is necessary to move the position frequently during welding to meet the welding needs of different directions. However, the power supply of existing welding machines The plug connector setting mode is too simple, so that the tightness after plugging is not high, and it is very easy to be dragged, pulled and other external factors to make the plug connector loose, resulting in poor contact and unable to supply power for welding normally, which has great disadvantages. , The protection ability of the plug joints of the existing welding machines is poor. Excessive force or repeated plugging during the plugging process may cause the pins to bend and deform, shorten the service life, and cause losses to users.
