[0029] The specific structure of the clamping mechanism 2 is described below:

[0030] Please refer to Figure 1 and Figure 2A clamping rod 24 is rotatably arranged on the clamping seat 23, a slide groove 242 is provided on the clamping rod 24, and an adjusting bolt 26 is connected to the contact 25, and the adjusting bolt 26 extends into the slide groove 242 and is fixed by the adjusting nut 27.

[0031] A handle 241 is provided at one end of the clamping rod 24 away from the slide slot 242. The clamping seat 23 rotatably connects the clamping rod 24 between the handle 241 and the slide slot 242, and an elastic member (not shown in the figure) is provided at the rotational connection.

[0034] Please refer to Figure 1 , a partition 6 is vertically arranged on the frame 1, and the partition 6 separates multiple groups of clamping mechanisms 2. The partition 6 in this embodiment separates four groups of clamping mechanisms 2, and two groups of clamping mechanisms 2 are respectively arranged at the left and right ends of the partition 6. Multiple groups of clamping mechanisms 2 are separated by the partition 6 to isolate and block the debris generated during the welding process, so that when the clamping mechanism 2 on one side of the partition 6 is welded, the operator can operate the clamping mechanism 2 on the other side of the partition 6 for clamping, and use the idle time during the welding process for clamping, so as to further improve the welding efficiency.

[0036] The specific working process of the utility model is as follows:

[0037] The operator hangs the U-shaped plate 7 on the loading rod 11 and places the threaded rod 8 on the loading plate 12. Press the handle 241 of the clamping rod 24 for clamping the U-shaped plate 7, and place the U-shaped plate 7 on the loading rod 11 on the frame 1 with the positioning block 32 as a reference. The inner side of one end of the U-shaped plate 7 fits the upper side of the frame 1, and the inner side of the other end of the U-shaped plate 7 fits the limiting cross bar 13. Release the handle 241, and the elastic member drives the clamping rod 24 to rotate around the clamping seat 23, thereby driving the contact 25 to abut against the fixed U-shaped plate 7. Press the handle 241 of the clamping rod 24 for clamping the threaded rod 8, one end of the threaded rod 8 abuts against the positioning rod 31 and the other end is pressed on the U-shaped plate 7. Release the handle 241, and the elastic member drives the clamping rod 24 to rotate around the clamping seat 23, thereby driving the contact 25 to abut against the fixed threaded rod 8. Complete the clamping of a set of clamping mechanisms 2. Repeat the above clamping operation to complete the clamping of another set of clamping mechanisms 2 on the same side of the partition 6.

[0038] Start the welding gun 4 and the moving mechanism 5, the vertical force arm 51 moves horizontally to the specified position, the horizontal slide bar descends along the vertical force arm 51 to the welding height, the vertical force arm 51 moves horizontally to drive the welding gun 4 to move along the welding position, after the welding is completed, the horizontal force arm 52 moves up along the vertical force arm 51 to complete the welding at one set of clamping mechanisms 2. The vertical force arm 51 moves horizontally to another set of clamping mechanisms 2, repeats the above welding action, and completes the welding at another set of clamping mechanisms 2.

[0039] During the welding process, the operator clamps the clamping mechanism 2 on the other side of the partition 6 .

[0040] It can be seen that in the above-mentioned U-shaped clamp processing device, the operator rotates the contact 25 around the clamping seat 23 to clamp and fix the U-shaped bent plate 7 and the threaded rod 8 at the specified position of the frame 1. Subsequently, it is only necessary to start the welding gun 4, and the vertical force arm 51 and the horizontal force arm 52 move according to the set route to complete the welding of the U-shaped bent plate 7 and the threaded rod 8. In addition, the two ends of the partition 6 can be welded and clamped respectively, which reduces downtime and improves production efficiency and automation.

[0041] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
