[0032] like Figure 8 As shown, it also includes a first long plate 706 and a second long plate 710. A symmetrical rectangular groove is opened on the top surface of the working plate 101. The first long plate 706 and the second long plate 710 are slidably connected in the rectangular groove of the working plate 101. The first long plate 706 and the second long plate 710 are the same size.

[0033] like Figure 8 As shown, it also includes a third protrusion 712, and the third protrusion 712 is fixedly connected to one side of the connecting frame 711. The first long plate 706 is rotatably connected to the spline shaft 708 on the right side. The first rubber wheel 707 and the second rubber wheel 709 are penetrated and clamped on the outer side of the circumference of the spline shaft 708. The first rubber wheel 707 and the second rubber wheel 709 are of the same size and material, and the first rubber wheel 707 and the second rubber wheel 709 can move on the spline shaft 708.

[0034] When two sleeves need to be welded, first manually place the first sleeve 506 and the second sleeve 605 on the rotating wheel 505 and the rotating shaft 604 respectively, and then start the second drive motor 6. The output shaft of the second drive motor 6 drives the threaded rod 602 to rotate, and the threaded rod 602 drives the second welding plate 601 to move, so that the second sleeve 605 is close to the first sleeve 506. In the initial state, the first rubber wheel 707 and the second rubber wheel 709 are away from the outer walls of the first sleeve 506 and the second sleeve 605. When the second welding plate 601 moves and drives the fourth protrusion 713 to move, the fourth protrusion 713 squeezes the third protrusion 712 to drive the first long plate 706 and the second long plate 710 to move and squeeze the elastic member in the rectangular groove of the working plate 101. At this time The first rubber wheel 707 and the second rubber wheel 709 move to fit with the outer walls of the first sleeve 506 and the second sleeve 605 respectively. During the movement of the second sleeve 605, the second sleeve 605 drives the second rubber wheel 709 to move on the spline shaft 708 through friction, so that the second sleeve 605 and the second rubber wheel 709 are in a fitted moving state. When the second sleeve 605 reaches the welding position, the second sliding column 703 is manually moved so that the second sliding column 703 and the second sleeve 605 are in a horizontal vertical position. After the second sliding column 703 is adjusted, the initial state limiting claw 704 is in an open state. The limiting claw 704 is manually pressed to make the limiting claw 704 contact with the gap between the plurality of blocks 705, so as to adjust the second sliding column 703. 3 is limited. In the initial state, the first sleeve 506 and the fixed column 701 are in a horizontal and vertical static state. By manually observing the distance between the fixed column 701 and the second sliding column 703, it is judged whether the first sliding column 702 is located at the center position of the sliding rail 7. When the first sliding column 702 is in a deviated state, the push rod 606 is started, and the output end of the push rod 606 moves and contacts the baffle 201. The baffle 201 is pushed to move by the output end of the push rod 606 to adjust the position of the first sliding column 702. During the adjustment process, the baffle 201 drives the sliding frame 2 to move. At this time, the spring column 103 is compressed, so that the first sliding column 702 is at the center position of the fixed column 701 and the second sliding column 703. When the first sliding column 702 moves to a position greater than When the second sliding column 703 is at the center position, the output end of the push rod 606 contracts, and the spring column 103 is reset to drive the sliding frame 2 to move for adjustment. After the adjustment is completed, the limiting claw 704 is manually pressed to make the gap between the limiting claw 704 and the clamping block 705 contact, and the first sliding column 702 is limited to prevent the first sliding column 702 from moving during the welding process of the welding nozzle 4, resulting in welding deviation. At this time, the welding nozzle 4 is at the position of the joint between the first sleeve 506 and the second sleeve 605, and then the first drive motor 5 is started. The output shaft of the first drive motor 5 rotates and drives the four rotating blocks 502 to rotate. During the rotation of the rotating block 502, it contacts the clamping block 504, and the clamping block 504 will spread and contact the inner wall of the first sleeve 506.The rotating block 502 limits the clamping block 504, and the clamping block 504 limits the first sleeve 506. At this time, the rotating wheel 505 slides in the circular groove of the first welding plate 501, and the rotating wheel 505 rotates and drives the first sleeve 506 to rotate. The rotation of the first sleeve 506 drives the first rubber wheel 707 to rotate through friction. The first rubber wheel 707 drives the second rubber wheel 709 to rotate through the spline shaft 708. The second rubber wheel 709 friction drives the second sleeve 506 to rotate, and then the electric slider 401 and the welding nozzle 4 are started. The electric slider 401 drives the welding nozzle 4 to move to weld the butt joint between the first sleeve 506 and the second sleeve 605. When the welding is completed, the electric slider 401 and the welding nozzle 4 are closed. , water is manually sprayed onto the welding place between the first sleeve 506 and the second sleeve 605 for cooling and shaping. In the initial state, the symmetrical welding shells 3 are far away from each other. By starting the telescopic rod 202 to telescope, the telescopic rod 202 brings the two welding shells 3 closer to each other, and the inner walls of the two welding shells 3 are respectively fitted with the welding place between the first sleeve 506 and the second sleeve 605. During the rotation of the first sleeve 506 and the second sleeve 605, the weld nodules generated by the first sleeve 506 and the second sleeve 605 can contact the nodule removal plate 302. In the initial state, the nodule removal plate 302 is in the middle of the welding shell 3. The nodule removal plate 302 rotates through the friction of the weld nodules at the welding place between the first sleeve 506 and the second sleeve 605, so that the nodule removal plate 302 can move in the slide groove of the welding shell 3, and the welding The elastic member in the slide groove of the connecting shell 3 is compressed by the up and down movement of the tumor removal plate 302. At this time, the first protrusion 301 contacts the second protrusion 304 and produces a bump. At the same time, the swing spring 305 drives the cleaning ball 306 to swing up and down, and the weld nodule at the welding place between the first sleeve 506 and the second sleeve 605 is knocked and cleaned. Through the friction of the tumor removal plate 302 on the weld nodule and the continuous knocking of the cleaning ball 306, the weld nodule is cleaned and scraped from the welding place between the first sleeve 506 and the second sleeve 605 to the working plate 101. When there is no weld nodule on the surface of the welding place between the first sleeve 506 and the second sleeve 605, the elastic member in the slide groove of the welding shell 3 is no longer subjected to force to drive the tumor removal plate 302 to slide to the initial state. After the cleaning is completed, the first drive motor 5 is turned off, and the second The first sleeve 506 and the second sleeve 605 stop rotating, the telescopic rod 202 is telescoped to make the two welding shells 3 move away from the outer walls of the first sleeve 506 and the second sleeve 605, the output shaft of the second drive motor 6 rotates in the opposite direction and drives the threaded rod 602 to rotate in the opposite direction, so that the rotating shaft 604 is separated from the second sleeve 605, and the second welding plate 601 drives the fourth protrusion 713 away from the third protrusion 712. At this time, the elastic member in the rectangular groove of the working plate 101 is no longer squeezed, and drives the first rubber wheel 707 and the second rubber wheel 605 away from the first sleeve 506 and the second sleeve 605, the first long plate 706 and the second long plate 710 are reset, and the first sleeve 506 and the second sleeve 605 that have been welded are manually taken out from the rotating wheel 505.The push rod 606 contracts the spring column 103 to drive the sliding frame 2 to reset, and the limiting claw 704 is manually pulled out from the clamping block 705 to release the limitation of the first sliding column 702 and the second sliding column 703, and the first sliding column 702 and the second sliding column 703 are manually reset.
