The support tube 32 is provided with a plurality of T-shaped slots 321 in a circumferentially inclined manner; The clamping block 1 33 is provided with a second T-slot 331 which is inclined in the opposite direction to the T-slot 1 321 .

During this process, the pull rod 351 slides along the T-slot 1 321 and the T-slot 2 331. Since the position of the support tube 32 is fixed, the position of the support tube 32 will not change when the pull rod 351 slides along the T-slot 1 321. The pull rod 351 will slide toward the center of the support tube 32.

The sliding of 3 can be adaptively adjusted according to the specifications of the stud, that is, the clamping assembly 3 can clamp a variety of different types of studs, that is, different types of studs are delivered to the welding mechanism 6 to meet different welding requirements, and then the studs and the plate to be welded are delivered to the top of the sliding bracket 5 and the welding mechanism 6, and the positioning mechanism 4 is used to position and clamp the plate, and then the welding mechanism 6 is used to clamp the stud and remove it from the clamping assembly 3, and it is moved to the plate to be welded for welding, thereby completing the automatic welding of the arc stud, that is, realizing the fully automatic welding work of automatic loading, automatic unloading and automatic welding, and effectively improving the welding efficiency of the arc stud.

The housing 61 defines an annular sealed cavity 612 , in which a movable ring 613 is provided for sealing and sliding movement. A plurality of fixed rods 614 are fixedly provided in a circumferential pattern on the movable ring 613 . The fixed rods 614 penetrate the housing 61 and are hingedly connected to the insulating plate 651 via connecting rods 615 . Two hydraulic telescopic rods 616 are fixedly provided on the housing 61 , and the hydraulic telescopic rods 616 can push the support tube 32 to slide.
[0018] During implementation, when the slide 52 drives the welding mechanism 6 to press down so that the stud enters the clamping range of the protective sleeve 64 and the multiple clamping blocks 65, the hydraulic pressure is used to drive the movable ring 613 to slide, so that the fixed rod 614 slides downward. At this time, the connecting rod 615 will deflect, that is, deflect from the vertical position to the horizontal position, and then push the multiple clamping blocks 65 to slide toward the center position of the protective sleeve 64, so that the clamping blocks 65 clamp the stud. Similarly, the sliding of the movable ring 613 and the clamping blocks The sliding of the second 65 can be adaptively adjusted according to the specifications of the stud, that is, the welding mechanism 6 can clamp and weld studs of various types. After the welding mechanism 6 clamps the stud, the hydraulic telescopic rod 616 is driven to extend, so that the hydraulic telescopic rod 616 is pressed against the support cylinder 32. At this time, the hydraulic pressure is used to drive the push plate 317 to slide, so that the rack 318 is separated from the gear 315, so that the rotation of the rotating rod 313 and the push rod 34 is unrestricted, and then the hydraulic telescopic rod 616 is driven to continue The hydraulic telescopic rod 616 extends, causing the support tube 32 to slide downward and drive the clamping block 33 to slide together. At this time, the clamping block 33 slides to the outside of the support tube 32 under the action of the pull rod 351, that is, the stud is loosened, and then the slide 52 is driven to slide upward and drive the welding mechanism 6 to slide upward, and the stud is removed from the clamping assembly 3. At the same time, after the hydraulic telescopic rod 616 pushes the support tube 32 to slide downward so that the clamping assembly 3 is reset, the hydraulic telescopic rod 616 is retracted. Return, then drive the movable seat 51 and drive the welding mechanism 6 to slide along the sliding bracket 5, so that the welding mechanism 6 drives the stud to move above the plate to be welded, and then continue to drive the slide 52 to slide downward, so that the welding mechanism 6 and the stud are pressed against the plate to be welded, and then use the power supply block to supply power, so that the stud is welded to the plate to be welded, and then release the clamp block 2 65, reset the welding mechanism 6 and the slide 52 and perform the next welding work, so as to realize automatic welding of arc studs.
[0019] In summary, when the present invention is implemented, an adaptive clamping assembly 3 is provided to clamp various types of studs, and the clamping process only requires pressing the push rod 34 downward to complete the clamping of the stud, thereby realizing rapid loading of the stud, and the sliding of the push rod 34 and the sliding of the clamping block 33 can be adaptively adjusted according to the diameter of the stud, thereby achieving stable clamping of the stud without manually adjusting the clamping parameters, and when the stud is transported to the welding mechanism 6, it is only necessary to push the support cylinder 32 downward to realize the loosening of the clamping assembly 3, thereby quickly removing the stud from the clamping assembly 3. , that is, the synergy between the welding mechanism 6 and the clamping assembly 3 is enhanced, thereby increasing the loading rate of the studs and further improving the welding efficiency of the studs. At the same time, a second clamping block 65 is slidingly set in the welding mechanism 6, and the movable ring 613, the fixed rod 614 and the connecting rod 615 are used to drive the second clamping block 65 to slide, so that the second clamping block 65 has a longer sliding adjustment distance, thereby enabling the welding mechanism 6 to effectively and stably clamp a variety of different types of studs, and thus effectively weld a variety of different types of studs without replacing the welding mechanism 6, further improving the welding efficiency of the studs.
