5. The welding jig of claim 4, wherein the wedge-shaped mating structure comprises:
a wedge-shaped groove (300) which is arranged on each side of each self-pressing sliding block (30);
the two sides of each end section in the length direction are respectively provided with an inclined part (322) which is distributed in a splayed shape, and the two inclined parts (322) on each end section extend into the corresponding wedge-shaped grooves (300) so that the pair of side push self-pressing sliding blocks (30) move oppositely.
6. The welding jig of claim 4, wherein the lateral compression cancellation control assembly (32) further comprises:
the avoidance hole (323) is arranged at the center of the cross lifting plate (320);
the control handle (324) is connected to the base (1) through a hinge structure penetrating through the avoidance hole (323), and the control handle (324) is positioned on the upper surface of the cross lifting plate (320);
the lateral pressing plane (325) is arranged on the control handle (324), when the lateral pressing plane (325) is matched with the upper surface of the cross lifting plate (320), the vertical elastic component (321) forces the cross lifting plate (320) to reset upwards and the transverse elastic component (31) forces the corresponding side to push the self-pressing sliding block (30) to press the lateral direction of the workpiece;
and the lateral pressing-removing arc-shaped surface (326) is arranged on the control handle (324), and when the control handle is rotated and the lateral pressing-removing arc-shaped surface (326) is not contacted with the upper surface of the cross lifting plate (320), the transverse elastic piece (31) is forced to elastically contract under the action of the wedge-shaped matching structure, so that the lateral pressing is removed.
7. The welding jig as claimed in claim 5, wherein a wedge-shaped stopper (33) is provided on the base (1) below each end section, and the wedge-shaped stopper (33) is used to limit two inclined portions (322) on one end section from excessively descending downwards.
8. The welding jig as claimed in claim 6, wherein a cross-shaped guide groove (21) is formed in the lower surface of the top pressing plate (2), the cross-shaped lifting plate (320) is disposed in the cross-shaped guide groove (21), a handle avoiding through hole (22) is formed in the central region of the top pressing plate (2), and the control handle (324) penetrates through the handle avoiding through hole (22).
9. The welding jig of claim 6, characterized in that there are two sets of vertical elastic assemblies (321), and the two sets of vertical elastic assemblies (321) are distributed on the X axis or the Y axis.
10. The welding jig of claim 1, characterized in that, articulated on base (1) have two be located top pressure strip (2) length direction both ends locking control frame (5), locking control frame (5) hasp in top pressure strip (2) length direction both ends.
11. Welding equipment, characterized in that, has the welding tool of any one of claims 1-10.
