Electric welding device

Abstract

The invention discloses an electric welding device which comprises a welding machine and a frame body; a converter is arranged at the left front end face of the frame body; a base body is arranged atthe bottom of the right side of the frame body; a plug is arranged at the bottom of the base body; a wire cable connected with the welding machine is arranged at the bottom of the plug; a cavity is formed in the bottom of the base body; sliding grooves are formed in the left side and the right side of the cavity; spiral rods are arranged in the sliding grooves; the tops of the spiral rods are connected with motors; a sliding plate is arranged in the cavity; the two side ends of the sliding plate enter into the sliding grooves and are connected with spiral threads of the spiral rods in a fit manner; a fixed connection block is arranged at the bottom of the sliding plate; the bottom of the fixed connection block passes through the end wall of the base body and is connected with the base bodyin a slidingly fit manner; first groove parts are formed in the fixed connection block in a left-and-right corresponding manner; placement grooves are formed in the tops of the first groove parts; aconnecting groove is formed in the bottom end face of the fixed connection block; a penetrable hole is formed in the part, between the connecting groove and each first groove part of the fixed connection block; a second groove part is formed in the outer side wall of each penetrable hole; first sliding blocks are arranged in the first groove parts; a first pressure spring is arranged between the top of each first sliding block and the corresponding placement groove; and sliding rods entering into the penetrable holes are arranged at the bottoms of the first sliding blocks. The electric weldingdevice is reasonable in structure and simple to operate, can be automatically plugged to be electrified and is high in plugging firmness.

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 rely on plug-in power supply to work normally. Therefore, whether the electric welding machine is plugged in stably and whether the power supply is safe is the basis for determining whether the electric welding machine can work normally. The cables are generally set long and have a large weight, which is easily affected by external factors such as dragging and pulling, which may cause loose connection and poor contact. There is a risk of electric shock due to the generation of electric arc, which has great disadvantages. In order to avoid the occurrence of safety accidents, emergency treatment devices should be added during use to increase the safety of power supply. Contents of the invention [0003] The technical problem to be solved by the ...

[0002] At present, electric welding machines are used more and more widely, and they rely on plug-in power supply to work normally. Therefore, whether the electric welding machine is plugged in stably and whether the power supply is safe is the basis for determining whether the electric welding machine can work normally. The cables are generally set long and have a large weight, which is easily affected by external factors such as dragging and pulling, which may cause loose connection and poor contact. Electric arc is generated, there is a danger of electric shock, and there are great disadvantages. In order to avoid safety accidents, emergency treatment devices should be added during use to increase the safety of power supply.
