[0021] In this embodiment, when arc welding is required, first slide the bearing seat 9 on the mounting plate 5. After determining the position, press the two adjacent groups of shift blocks 13 closer to each other, and the ends of the two groups of shift blocks 13 are disengaged from the locking blocks 15 in the housing 11. Then rotate the rotating shaft 10 and adjust it to a suitable angle. Release the shift block 13. Under the compression of the compression spring 14, one end of the shift block 13 re-engages with the locking block 15 to limit the angle of the telescopic rod 12. Finally, the beam is divided and assembled inside the clamping jaw 8 so that the beam is divided into an angle corresponding to the external angle of the instrument beam for arc welding. This can improve the accuracy of arc welding and facilitate unified arc welding of multiple groups of beams.

[0022] As an implementation method, Figure 4 As shown, a slide groove 6 is provided inside the mounting plate 5 , and the bearing seat 9 is slidably mounted inside the slide groove 6 .

[0023] In this embodiment, the number of mounting plates 5 and fixtures 7 is determined based on the number of beams that need to be arc welded. After the beams are divided, the position of the bearing seat 9 on the mounting plate 5 is moved to weld beams of different lengths with the instrument beams.

[0024] As an implementation method, Figure 4 As shown, there are at least three groups of mounting plates 5 , and two adjacent groups of clamp members 7 are arranged in a mirror-symmetrical manner with respect to the center of the mounting plate 5 .

[0025] In this embodiment, by positioning between multiple sets of mounting plates 5 and positioning plates 2, arc welding can be performed at different positions of the instrument beam, and the mirror-image clamp 7 is suitable for arc welding at different angles outside the instrument beam.

[0026] As an implementation method, Figure 4 As shown, a slot corresponding to the shift block 13 is formed around the inside of the engaging block 15 , and the slot is in an arc shape.

[0027] In this embodiment, by pressing two adjacent groups of shift blocks 13 together, the ends of the two groups of shift blocks 13 are disengaged from the locking blocks 15 in the housing 11, and then the rotating shaft 10 is rotated to adjust to a suitable angle, and the shift blocks 13 are released.

[0030] As an implementation method, Figure 1 As shown, the clamp frame 1 is arranged in a ring structure, and the clamp frame 1 and the mounting plate 5 are both square steel components.

[0031] In this embodiment, the annular clamp frame 1 facilitates arc welding at different positions on the outside of the instrument beam. At the same time, the clamp frame 1 and the mounting plate 5 are made of square steel to increase the overall structural strength.

[0032] Working principle: When in use, first insert the two ends of the instrument beam to be welded into the through holes 4 opened in the end plate mounting frame 3 respectively, divide the beams into the number according to the number of arc welding, determine the number of mounting plates 5 and fixtures 7, and make adaptive adjustments between the mounting plates 5 and the fixture frame 1 to increase or decrease; when arc welding is required, first slide the position of the bearing seat 9 on the mounting plate 5, and after determining the position, press the two adjacent groups of shift blocks 13 to move closer to each other, and the ends of the two groups of shift blocks 13 will be disengaged from the engaging blocks 15 in the housing 11, and then Manually move the telescopic rod 12 or rotate the other set of engaging blocks 15 at one end of the rotating shaft 10, rotate along the rotating shaft 10, adjust to a suitable angle, loosen the shift block 13, and under the compression of the compression spring 14, one end of the shift block 13 re-engages with the engaging block 15 to limit the angle of the telescopic rod 12. Finally, the beam is divided and assembled inside the clamping jaw 8 so that the beam is divided into corresponding angles with the external angles of the instrument beam, and then arc welding is performed. This can improve the accuracy of arc welding, facilitate unified arc welding of multiple groups of beams, and reduce workload.
