In the production and processing processes of a plurality of devices, a welding technology is often needed, most of the existing welding technologies are manually carried out, but the problems of low efficiency and high cost exist in manual operation; the automatic welding equipment can solve the problem, and the automatic welding equipment is used for replacing manpower to weld so as to improve the production efficiency of products. However, most of the existing welding machines are large in size and high in cost, can only weld the fixed part of the part to be welded, and when a plurality of parts are required to be welded simultaneously, the position of the part to be welded needs to be manually replaced, so that the operation process is complicated. Based on this, chinese patent CN107138889A discloses a welding mechanism, which comprises a workbench, an automatic lifting support, a welding head, a cantilever, an elastic pressing member and a rotary material discharge disc; the automatic lifting support is arranged at one end of the workbench and comprises two stand columns which are arranged in parallel and can automatically stretch and retract and a first cross rod which is connected with the top ends of the two stand columns, the lower parts of the two stand columns are also connected with ball screws, the ball screws are driven by a first driving mechanism, and the ball screws are provided with sliding blocks; the welding head is arranged on the sliding block, and the working surface of the welding head faces the rotary discharging disc; the cantilever is vertically connected with the first cross rod; the elastic pressing piece is arranged vertical to the table surface of the workbench, and the top end of the elastic pressing piece is connected with the cantilever; the rotary type blowing dish includes blowing dish body, locates the second actuating mechanism of blowing dish body bottom, and second actuating mechanism drives the blowing dish body and does the rotation.

However, the welding mechanism disclosed above has a technical problem of insufficient stability. Specifically, the working principle of the welding mechanism is as follows: firstly, placing a to-be-welded piece on a material placing disc body, and controlling a movable part of an automatically telescopic upright column to drive an elastic pressing piece to move downwards until the elastic pressing piece fixes the to-be-welded piece; when spot welding is needed, the first driving mechanism and the third driving mechanism are utilized to drive the welding head to move so as to realize position adjustment, the welding head is right opposite to a position to be welded, and then welding is carried out; when wire welding is needed, the first driving mechanism and the third driving mechanism are utilized to drive the welding head to move to a starting point of a position to be welded, and the welding head moves linearly along the part to be welded, and is continuously welded in the moving process; when multi-surface welding is needed, after one surface is welded, the second driving mechanism is used for driving the welding disc body to rotate, the other surface to be welded is opposite to the welding head, and welding is carried out according to the welding condition or until the whole welding work is completed. Therefore, when the first driving mechanism or the third driving mechanism drives the welding head to adjust the position, the action structural members do not form a mutual supported connection relationship, so that the action stability of the welding head in the advancing process is not strong, and the welding head may not fall into a preset welding work area due to the deviation of the stability of the driving mechanism; thereby affecting the accuracy of the welding process.
