For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0037] Please refer to Figures 1 to 5 , the present utility model provides a welding clamping mechanism, which includes a bottom lifting drive 1, a bottom lifting seat 2, a welding head connecting seat 3, and a clamping mechanism 4. The clamping mechanism 4 includes a clamping plate 41, a fixing frame 42, a reset member 43, a first clamping member 44, and a second clamping member 45;

[0038] The driving end of the bottom lifting drive 1 is drivingly connected to the bottom lifting seat 2 to drive the bottom lifting seat 2 to rise or fall; the welding head connecting seat 3 is arranged on the bottom lifting seat 2 for fixing the welding machine head; the clamping plate 41 is fixed at the front proximal end of the bottom lifting seat 2; the fixing frame 42 is fixedly arranged on the front side of the clamping plate 41;

[0039] The middle parts of the first clamping member 44 and the second clamping member 45 are rotationally assembled on the fixing frame 42 and form a pliers-like structure; the tops of the first clamping member 44 and the second clamping member 45 cooperate to form a clamping station for clamping the leads and the terminals of the transformer;

[0040] The clamping plate 41 is provided with a guiding notch 411; the width between the two side walls of the guiding notch 411 gradually narrows along the direction from the opening edge to the bottom of the guiding notch 411; rollers 46 are rotatably assembled at the bottoms of both the first clamping member 44 and the second clamping member 45; one end of the reset member 43 is arranged at the proximal end of the lower part of the first clamping member 44, and one end of the reset member 43 is arranged at the proximal end of the lower part of the second clamping member 45, so that the side walls of the rollers 46 are in close contact with the side walls of the guiding notch 411.

[0043] When it is necessary to clamp the lead and the terminal of the transformer, the bottom lifting drive 1 drives the bottom lifting seat 2 to rise, thereby driving the clamping plate 41 to rise synchronously. Since the width between the two side walls of the guiding notch 411 gradually narrows along the direction from the opening edge to the bottom of the guiding notch 411, as the clamping plate 41 rises, the distance between the two rollers gradually decreases, and the reset member 43 is compressed, so that the distance between the top of the first clamping member 44 and the top of the second clamping member 45 gradually decreases, thereby achieving the purpose of clamping the lead and the terminal of the transformer by the top of the first clamping member 44 and the top of the second clamping member 45.

[0044] When it is necessary to loosen the welded lead and the terminal of the transformer, the bottom lifting drive 1 drives the bottom lifting seat 2 to descend, thereby driving the clamping plate 41 to descend synchronously. Since the width between the two side walls of the guiding notch 411 gradually narrows along the direction from the opening edge to the bottom of the guiding notch 411, as the clamping plate 41 descends, the reset member 43 drives the bottoms of the first clamping member 44 and the second clamping member 45 to reset, the distance between the two rollers gradually increases, so that the distance between the top of the first clamping member 44 and the top of the second clamping member 45 gradually increases, and the top of the first clamping member 44 and the top of the second clamping member 45 loosen the lead and the terminal of the transformer.

[0045] The fixing frame 42 serves to fix the first clamping member 44 and the second clamping member 45, so that the first clamping member 44 and the second clamping member 45 form an embedded structure.

[0046] In a specific embodiment of the present utility model, the reset member 43 is a spring; the reset member 43 can make the side wall of the roller 46 closely adhere to the side wall of the guiding notch 411, and by reducing or increasing the distance between the two rollers 46 through the guiding notch 411, the purpose of clamping the lead and the terminal of the transformer is achieved.

[0047] The roller 46 can reduce the frictional force between the first clamping member 44 and the guiding notch 411, and between the second clamping member 45 and the guiding notch 411, making the processes of clamping and loosening smoother. In a specific embodiment of the present utility model, the bottom lifting drive 1 is a lifting motor.

[0048] A welding head connecting seat 3 is provided on the bottom lifting seat 2. The welding head connecting seat 3 is used to install the welding machine head, thereby driving the installed welding machine head to move up or down, so that the welding head on the welding machine head can approach the lead and the terminal of the transformer, thereby achieving welding.

[0049] The guiding notch 411 includes a loosening section, a transition section, and a clamping section; the loosening section is located at the opening of the guiding notch 411, the clamping section is located at the bottom of the guiding notch 411, and the transition section is located between the loosening section and the clamping section; the distance between the two side walls of the loosening section is greater than the distance between the two side walls of the clamping section, and the distance between the two side walls of the transition section gradually decreases from top to bottom.

[0050] The welding clamping mechanism is provided with a clamping plate 41, a fixing frame 42, a reset member 43, a first clamping member 44, and a second clamping member 45. By using the action of the bottom lifting drive 1 driving the bottom lifting seat 2 and the welding machine head to move up or down during the welding process, the operation of clamping or loosening the lead and the terminal of the transformer by the top of the first clamping member 44 and the second clamping member 45 is realized.
