The front side of the box 2 is fixedly connected to a support plate 10 and slidably connected to a support plate 2 11. A right-angle plate 12 and a right-angle plate 2 13 are respectively provided above the support plate 10 and the support plate 2 11. The support plate 10 and the right-angle plate 12, as well as the support plate 2 11 and the right-angle plate 2 13 are fixedly connected by two support columns 14. A second motor 15 is fixedly connected to the right-angle plate 12. A rotating rod 17 is rotatably connected to the side wall of the right-angle plate 2 13 through a bearing 16. The rotating rod 17 and the output shaft of the second motor 15 are fixedly connected to a fixed seat 18, and a clamping assembly 19 is provided on the fixed seat 18.

[0026] As shown in FIG. 1 and FIG. 2 , a plurality of columns 20 are fixedly connected to the bottom of the welding platform 1 in the present invention. The number of the columns 20 is four and they are distributed in a rectangular shape, thereby improving the stability of the welding platform 1 .

[0027] As shown in Figures 1, 2 and 3, in the present invention, the end of the screw rod 4 away from the first motor 3 is rotatably connected to the fixed box 2 through the second bearing 21, which improves the stability of the screw rod 4 when rotating; a limiting groove 22 for the sliding of the limiting slider 6 is provided on the top wall of the fixed box 2. Through the cooperation of the limiting slider 6 and the limiting groove 22, a limiting guide function is played, and when the screw rod 4 rotates, the screw rod sleeve 5 will slide.

[0028] As shown in Figures 1, 3 and 5, in the present invention, two guide sliders 23 are fixedly connected to the bottom of the support plate 2 11, and a guide groove 24 for the guide slider 23 to slide is provided on the welding platform 1, which improves the sliding stability of the support plate 2 11; the support plate 2 11 is a T-shaped structure and a limiting component 25 is provided at both ends of the support plate 2 11, and the support plate 2 11 is limited and fixed by the limiting component 25, so that the support plate 2 11 is limited and fixed in a suitable position.

[0029] As shown in Figure 5, the limiting assembly 25 in the present invention includes a connecting rod 25.1 that passes through the support plate 2 11, the top of the connecting rod 25.1 is fixedly connected to a pull block 25.2, the bottom of the connecting rod 25.1 is fixedly connected to a fixed block 25.3, the bottom of the fixed block 25.3 is fixedly connected to a limiting column 25.4, and the fixed block 25.3 is connected to the support plate 2 11 by a spring 25.5 that is sleeved on the outside of the connecting rod 25.1; a through hole is provided on the support plate 2 11 for the connecting rod 25.1 to pass through, and a plurality of limiting grooves 25.6 that are compatible with the limiting column 25.4 are provided on the welding platform 1.

[0030] When the present invention is implemented, the pulling block 25.2 is pulled upward, and the fixing block 25.3 is driven to move upward through the connecting rod 25.1. At this time, the spring 25.5 is in a compressed state, and the limiting column 25.4 moves upward to disengage it from the limiting groove 25.6. At this time, the support plate 2 11 can be controlled to slide. When the support plate 2 11 slides to a suitable position, the pulling block 25.2 is released. At this time, the elastic potential energy of the spring 25.5 restores it to its original state, thereby causing the limiting column 25.4 to move downward into the limiting groove 25.6. At this time, the support plate 2 11 is limited and fixed by the cooperation of the limiting column 25.4 and the limiting groove 25.6, thereby making the metal parts more stable during the welding process.

[0031] As shown in Figure 6, the clamping assembly 19 in the present invention includes a screw 19.1 passing through the top wall of the fixed seat 18 and a soft pad 19.2 arranged on the bottom wall of the fixed seat 18. The top of the screw 19.1 is fixedly connected to the rotating rod 19.3, and the bottom end of the screw 19.1 is rotatably connected to the pressure plate 19.5 through the bearing three 19.4; the screw 19.1 is threadedly connected to the fixed seat 18 and a thread groove for the screw 19.1 to pass through is provided on the top wall of the fixed seat 18. The middle of the pressure plate 19.5 is an arc-shaped structure and a slider 19.6 is fixedly connected to one side of the pressure plate 19.5. The side wall of the fixed seat 18 is provided with a slide groove 19.7 for the slider 19.6 to slide.

[0032] During the specific implementation of the present invention, the metal parts are placed on the soft pad 19.2 in the fixing seat 18, and then the rotary rod 19.3 is controlled to rotate, driving the screw 19.1 to rotate. Since the screw 19.1 is threadedly connected to the fixing seat 18, and the screw 19.1 is rotationally connected to the pressure plate 19.5 through the bearing three 19.4, when the screw 19.1 rotates, the pressure plate 19.5 can slide downward. The cooperation of the slider 19.6 and the slide groove 19.7 improves the stability of the pressure plate 19.5 when sliding. At this time, the metal parts are pressed and fixed by the pressure plate 19.5, so that the metal parts are more stable during the welding process.

[0033] The present invention also includes a control module and a power supply module electrically connected to the first motor 3, the telescopic rod 8, the welder 9, and the second motor 15. The control module controls the operation of the first motor 3, the telescopic rod 8, the welder 9, and the second motor 15, thereby improving the degree of automation of welding.

[0034] Working principle: When the present invention is implemented, the limiting component 25 is first used to disengage the limiting column 25.4 from the limiting groove 25.6. At this time, the support plate 21 is controlled to slide, so as to adjust the distance between the two clamping components 19 according to the length of the metal parts. After adjusting to the appropriate position, the supporting plate 21 is fixed by the limiting component 25, and then the two metal parts to be welded are fixed in the two fixing seats 18 respectively by the clamping components 19, thereby improving the stability during welding; when welding metal parts, the first motor 3 is controlled to start by the control module to drive the screw rod 4 to rotate. Due to the cooperation between the limiting slider 6 and the limiting slide groove 22, when the screw rod 4 rotates The screw sleeve 5 will slide, thereby driving the right-angle frame 7 to slide through the limit slider 6, thereby adjusting the position of the welding machine 9 to move it above the welding point of the metal parts, and then controlling the movable shaft of the telescopic rod 8 to extend to enable the welding machine 9 to weld the metal parts; in the process of welding the metal parts, the second motor 15 is started by the control module, and the output shaft of the second motor 15 will rotate. At this time, the two clamping assemblies 19 clamp and fix the welded metal parts. Therefore, when the output shaft of the second motor 15 rotates, the metal parts will be rotated through the fixing seat 18 and the clamping assembly 19. Therefore, the metal parts can be processed and welded on the front and back sides or at multiple angles, thereby improving the practicality of welding.
