[0034] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0035] Please refer to Figure 1-8 , the present utility model provides a technical solution: a compact hot wire pulsed TIG welding equipment, including a main body 1 of the TIG welding equipment, a fixed bracket 2, an electric telescopic rod 3, a welding head 4, a fixed plate 5, a lead screw 6, an adjusting block 7, a movable block 8, a support block 9, a connection block 10, a movable bracket 11, a spring 12, a positioning block 13, a fixed rod 14, a fixed groove 15, a welding table 16, a fixing mechanism 17, a vertical plate 18, a fixing bolt 19, a fixed rail 20 and a pressing plate 21.

[0036] When using this compact hot wire pulsed TIG welding equipment, such as Figure 1 , Figure 6 , Figure 7 and Figure 8As shown, a fixed bracket 2 is welded to the upper left end of the TIG welding equipment main body 1, and an electric telescopic rod 3 is fixedly installed at the upper end of the fixed bracket 2. The output end of the electric telescopic rod 3 is fixedly connected to a welding head 4. A welding table 16 is arranged below the welding head 4. The workpiece to be welded is first placed on the welding table 16. Through the setting of the fixing mechanism 17, the fixing mechanism 17 is arranged at equal angles on the upper end of the welding table 16. The fixing mechanism 17 includes a vertical plate 18 fixedly connected to the edge of the upper end of the welding table 16, a fixing bolt 19 for adjustment, a fixing rail 20 arranged at the lower end of the fixing bolt 19, and a pressing plate 21 for pressing and limiting;

[0037] First, according to the size of the workpiece to be welded, by pulling the pressing plate 21, the pressing plate 21 drives the fixing rail 20 to move at the lower end of the fixing bolt 19, so that the pressing plate 21 moves towards the side close to the vertical central axis of the welding table 16. The pressing plate 21 moves to the corresponding position above the workpiece. Then, by rotating the fixing bolt 19 threadedly connected to the upper end of the vertical plate 18, the lower end of the fixing bolt 19 rotates in the middle of the fixing rail 20, so that the fixing rail 20 drives the pressing plate 21 to move downward, and the workpiece on the welding table 16 is stably clamped and fixed by the pressing plate 21. After the fixing is completed, start the TIG welding equipment main body 1 and the electric telescopic rod 3 installed at the upper end of the fixed bracket 2, and drive the welding head 4 to move downward through the electric telescopic rod 3 to weld the workpiece;

[0038] In addition, when it is necessary to adjust the welding position and angle of the workpiece, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, by rotating the lead screw 6, the lead screw 6 rotates in the middle of the fixing plate 5. The lead screw 6 is threadedly connected to the adjusting block 7, and then drives the adjusting block 7 to move in the fixing plate 5. Both the front and rear ends of the adjusting block 7 are fixedly connected with movable blocks 8. The adjusting block 7 drives the movable blocks 8 to slide with the fixing plate 5, so as to improve the stability of the adjusting block 7 during the movement. Moreover, by pushing the fixed rod 14, the fixed rod 14 pushes the movable bracket 11 to slide with the support block 9. The movable bracket 11 squeezes the spring 12, so that the spring 12 undergoes elastic deformation. At this time, the movable bracket 11 drives the positioning block 13 to move leftward, so that the positioning block 13 is pulled out from the fixing groove 15, and then the limit between the connecting block 10 and the support block 9 is released;

[0039] Then rotate the welding table 16 so that the welding table 16 drives the rotation between the connecting block 10 and the support block 9, thereby facilitating the adjustment of the position of the workpiece. When the welding position is moved to the lower end of the welding head 4, directly loosen the fixing rod 14. At this time, the spring 12 resumes its elastic deformation, driving the sliding between the movable bracket 11 and the support block 9. At this time, the movable bracket 11 drives the positioning block 13 to engage in the fixing groove 15 at the corresponding position, thereby facilitating the limitation between the support block 9 and the connecting block 10, and thus realizing the adjustment of the welding angle and position of the workpiece. There is no need to remove the workpiece for adjustment, which simplifies the operation steps and greatly improves the efficiency of the welding process of the workpiece.

[0040] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
