DETAILED DESCRIPTION

[0021] 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 belong to the scope of protection of the utility model.

[0022] Embodiments of the present utility model:

[0023] A clamp for assembling and welding vertical sheet metal parts comprises a base 1, a plurality of support rods 17 are fixedly tilted inwardly on one side of the top of the base 1, and the tops of the plurality of support rods 17 are fixedly connected to the bottom of the same base plate 2. The base plate 2 is supported by the arrangement of the support rods 17, and a movable plate 3 is hingedly connected to one side of the base plate 2. A rotating rod 4 is arranged at the bottom of both the base plate 2 and the movable plate 3, a threaded sliding seat 5 is threadedly mounted on the rotating rod 4, a push rod 6 is hinged on the threaded sliding seat 5, one end of the push rod 6 is hingedly connected to a hinge seat 7 fixed on the back of the movable plate 3, and the movable plate 3 is adjusted by the arrangement of the rotating rod 4, the threaded sliding seat 5, the push rod 6 and the hinge seat 7.

[0024] The bottom plate 2 and the movable plate 3 are both provided with a plurality of slide grooves 8. It should be noted that the cross-section of the slide groove 8 is in the shape of a "convex" character, and a slider 91 is slidably installed inside the slide groove 8. A threaded column 92 is threadedly installed on the slider 91. A limiting protrusion 93 is fixed on the top of the threaded column 92. Through the setting of the limiting protrusion 93, the sheet metal parts can be clamped to prevent the sheet metal parts from loosening or falling during the welding process. It should be noted that a limiting groove 94 is provided on one side of the slide groove 8, and the two inner side walls of the limiting groove 94 are both in the shape of a wavy line, so that after the end of the threaded column 92 away from the limiting protrusion 93 is inserted into the interior of the limiting groove 94, it plays a limiting role to prevent the threaded column 92 from sliding during use.

[0025] One end of the rotating rod 4 is rotatably connected to a support seat 10 fixed on the top of the base 1, a rotating seat 11 is fixed to the bottom of the base plate 2, and the other end of the rotating rod 4 passes through the rotating seat 11 to be fixed with a rotating handwheel 12. The rotating handwheel 12 is arranged to facilitate the rotation of the rotating rod 4, and a wear-resistant coating is arranged on the rotating handwheel 12. The wear-resistant coating can increase friction and reduce slipping.

[0026] A protrusion 13 is fixed to one side of the base plate 2, and an "L"-shaped insertion rod 14 is inserted on the protrusion 13. A locking plate 15 is fixed to one end of the rotating rod 4. A plurality of insertion holes 16 are equidistantly provided on the locking plate 15 along the circumferential direction. When the bottom end of the insertion rod 14 is inserted into any insertion hole 16, the rotating rod 4 is locked to prevent the rotating rod 4 from rotating during use.

[0027] When welding sheet metal parts, first adjust the angle between the bottom plate 2 and the movable plate 3 according to the needs of sheet metal welding. When adjusting the angle between the bottom plate 2 and the movable plate 3, first rotate the rotating hand wheel 12, and the rotating hand wheel 12 drives the rotating rod 4 to rotate. The rotating rod 4 can drive the threaded sliding seat 5 to move during the rotation process. The threaded sliding seat 5 can push or pull the push rod 6 during the movement. The push rod 6 can drive the angle of the movable plate 3 to rotate through the hinge seat 7, so that the bottom plate 2 and the movable plate 3 can be adjusted according to the needs of sheet metal welding. The angle of the plate 3 is adjusted. After the angle adjustment of the bottom plate 2 and the movable plate 3 is completed, the bottom end of the insertion rod 14 is inserted into the corresponding insertion hole 16 to lock the rotating rod 4. Then, the two sheet metal parts to be welded are placed on the bottom plate 2 and the movable plate 3 respectively, and the slider 91 is slid again. The slider 91 drives the threaded column 92 to slide. If the outer surface of the threaded column 92 is in contact with the side wall of the sheet metal, the threaded column 92 is tightened, and the sheet metal is tightened by the limiting protrusion 93, so that the sheet metal parts can be welded after tightening.
