[0029] As Figures 1-4As shown, the double-sided welding fixture of the embodiment comprises a hollow fixture base plate 1, a fixed limiting block 3 arranged on the fixture base plate 1, a push-pull limiting assembly movably abutting against the fixed limiting block 3,

[0030] Each group of push-pull limiting assemblies and the corresponding fixed limiting block 3 form a complete limiting part group for clamping the special-shaped frame product 2.

[0031] The fixed limiting block 3 abuts against the outer side of the frame product 2, and at least two fixed limiting blocks 3 are arranged at each limiting edge of the frame product 2.

[0032] The push-pull limiting assembly comprises an elbow clamp 4 fixed on the fixture base plate 1 and a pressing block 5 pushed by the elbow clamp 4 to the frame product 2.

[0033] The push-pull limiting assembly and the fixed limiting block 3 are respectively located at the inner and outer sides of the closed frame product 2 or at the multiple side walls of the frame product 2 with an extended frame.

[0034] The push-pull limiting assembly is located at the inner side of the frame product 2, and the fixed limiting block 3 abuts against the outer side of the frame product 2.

[0035] The elbow clamp 4 of the push-pull limiting assembly is directed to the top corner of the frame product 2.

[0036] The pressing block 5 equipped with the elbow clamp 4 comprises a block body 501, the block body 501 is provided with a connecting groove 502 for accommodating the push rod of the elbow clamp 4, and two pressing inclined walls 503 are formed on the side of the block body 501 away from the connecting groove 502, and the pressing inclined walls 503 abut against two adjacent inner walls of the frame product 2.

[0037] The two pressing inclined walls 503 are recessed between them.

[0038] The pressing block 5 is a symmetrical piece.

[0039] A plurality of special-shaped hollow grooves 101 are arranged on the fixture base plate 1, and the positions of the hollow grooves 101 correspond to the welding points of the frame product 2.

[0040] The adjacent hollow grooves 101 are discontinuously arranged.

[0041] The specific structure and working principle of the utility model are as follows:

[0042] As shown in Figure 1 and Figure 4 , they are two implementation manners of the utility model, Figure 1 aiming at the fully-closed frame product 2, Figure 4 aiming at the non-closed frame product 2 with an extended frame.

[0043] AsFigures 1-3 As shown, taking a frame product 2 with five side frames as an example, a plurality of fixed limiting blocks 3 are arranged on the rectangular clamp base plate 1 according to the outer contour of the frame product 2, and the arrangement requirement of the fixed limiting block 3 is that one fixed limiting block 3 is arranged at each end of each side frame, so that each side frame can be stably stressed.

[0044] A plurality of elbow clamps 4 are arranged in the area surrounded by the fixed limiting block 3, i.e. the inside of the frame product, and the number of the elbow clamps 4 is the same as the number of the top corners of the frame product 2, each elbow clamp 4 is provided with a pushing block 5, the pushing block 5 is a symmetrical piece, provided with a connecting groove 502 for accommodating the end of the pushing rod of the elbow clamp 4, and two top pressing inclined walls 503 are formed on the side of the pushing block 5 facing the frame product 2, the two top pressing inclined walls 503 are parallel to the adjacent inner walls on the two sides of the corresponding top corner and can be completely attached to the two inner walls. In order to reduce the rigid impact and reduce the gap at the top corner, the recess is arranged between the two top pressing inclined walls 503.

[0045] When the tool is used, the mechanical hand clamps the clamp base plate 1, and allows the welding gun to weld the welding position from the front and the back of the hollow groove 101.

[0046] As shown, Figure 4 As shown, taking a frame product 2 with five side frames as an example, a plurality of fixed limiting blocks 3 are arranged on the rectangular clamp base plate 1 according to the outer contour of the frame product 2, and the arrangement requirement of the fixed limiting block 3 is that one fixed limiting block 3 is arranged at each end of each side frame, so that each side frame can be stably stressed.
