DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figure 1-3 A busbar welding tool shown includes a fixture body 12 and a lower rotating sandwich plate 5 installed at the front end of the fixture body 12;

[0022] An upper rotating sandwich plate 6 is arranged on the front side of the lower rotating sandwich plate 5;

[0023] Cam followers 3 are provided on the left side of the upper rotating sandwich plate 6 and close to the upper and lower sides respectively;

[0024] A track plate 2 is arranged between the two cam followers 3, a toggle clamp 1 is arranged on the left side of the track plate 2, and a product body 10 is arranged on the front side of the upper rotating sandwich plate 6. Before laser welding, the fixture body 12 is first placed on the stator, and then the product body 10 is fixed between the lower rotating sandwich plate 5 and the upper rotating sandwich plate 6, and then the toggle clamp 1 is pushed to drive the track plate 2 to move, and then the cam follower 3 is pushed to drive the lower rotating sandwich plate 5 and the upper rotating sandwich plate 6 to rotate in opposite directions relative to the center, so as to complete the clamping of the copper wire on the product body 10, so as to perform the subsequent laser welding operation of the copper wire end;

[0025] A quick-release splint 9 is provided on the front side of the product body 10. The front end outer wall of the quick-release splint 9 and respectively close to the upper and lower sides are provided with backward penetrating contour pins 8 to limit the position of the product body 10. When limiting the position of the product body 10, the position of the product body 10 can be pre-positioned by the quick-release splint 9, and then two contour pins 8 are inserted to fix the position of the product body 10 to avoid the position displacement of the product body 10 during operation.

[0026] like Figure 1 As shown, the front end outer wall of the quick-release splint 9 and the upper and lower sides are respectively provided with openings for the insertion of the contour pins 8. After being inserted into the quick-release splint 9, the two contour pins 8 need to be rotated clockwise to lock and restrict the position of the product body 10 between the product body 10. After rotating counterclockwise, the two contour pins 8 can be pulled outward to unlock the restriction of the quick-release splint 9 on the product body 10. The quick-release splint 9 is arc-shaped.

[0027] The profiling pin 8 can be inserted into the through hole and then rotated clockwise to fix the product body 10 and the quick-release clamp 9. When the product body 10 is welded, the profiling pin 8 can be rotated counterclockwise and pulled out to contact the product body 10.

[0028] like Figure 1 As shown, a positioning pin b11 is provided on the lower side of the clamp body 12 to limit the position of the lower rotating sandwich plate 5 , and a positioning pin a7 is provided on the upper side of the clamp body 12 to limit the position of the upper rotating sandwich plate 6 .

[0029] The positions of the lower rotating sandwich plate 5 and the upper rotating sandwich plate 6 are respectively limited by the positioning pin b11 and the positioning pin a7, so as to ensure that the lower rotating sandwich plate 5 and the upper rotating sandwich plate 6 are in a stable dynamic state during the rotation process and avoid up and down shaking.

[0030] like Figure 1 As shown, a rotation positioning shaft 4 is provided between the lower rotating sandwich plate 5, the upper rotating sandwich plate 6 and the clamp body 12 to limit the rotation center between the lower rotating sandwich plate 5 and the upper rotating sandwich plate 6. When the elbow clamp 1 is pushed by an external force, it will drive the track plate 2 to move and push the cam follower 3 to move. During the movement, the cam follower 3 will drive the lower rotating sandwich plate 5 to rotate counterclockwise, and the cam follower 3 will drive the upper rotating sandwich plate 6 to rotate clockwise.

[0031] The rotation center of the lower rotating sandwich plate 5 and the upper rotating sandwich plate 6 can be limited by rotating the positioning shaft 4 to avoid misalignment between the lower rotating sandwich plate 5 and the upper rotating sandwich plate 6 during rotation. After being pushed, the elbow clamp 1 will cause the track plate 2 to push the cam follower 3 to control the lower rotating sandwich plate 5 and the upper rotating sandwich plate 6 to rotate and clamp the copper wire of the product body 10.

[0032] The implementation principle of this embodiment is as follows: before laser welding, first place the clamp body 12 on the stator, then fix the product body 10 between the lower rotating sandwich plate 5 and the upper rotating sandwich plate 6, then push the elbow clamp 1 to drive the track plate 2 to move, and then push the cam follower 3 to drive the lower rotating sandwich plate 5 and the upper rotating sandwich plate 6 to rotate in opposite directions relative to the center, so as to complete the clamping of the copper wire on the product body 10, so as to perform the subsequent laser welding operation of the copper wire end. When limiting the position of the product body 10, the position of the product body 10 can be pre-positioned by the quick-release clamp 9, and then two contoured pins 8 are inserted to fix the position of the product body 10 to avoid the position displacement of the product body 10 during the working process.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
