Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figure 1-Figure 11 As shown, the technical solution adopted by the present invention is as follows: a grounding body welding device includes a mounting frame, a welding gun 20 and a clamp 13.

[0034] The mounting frame includes a bottom plate 1 and a vertical plate 2. The vertical plates 2 are fixedly mounted on both the left and right ends of the bottom plate 1.

A support ring 19 is fixedly mounted on the lower side of the horizontal portion of the support plate 8, and the axis of the support ring 19 is horizontally arranged and parallel to the length direction of the bottom plate 1.

[0035] The welding gun 20 is disposed on the support ring 19 , and a driving component for driving the welding gun 20 to move along the circumference of the support ring 19 is disposed on the support ring 19 .

[0036] A sliding ring 24 is slidably mounted on the support ring 19, and an electric telescopic rod 25 is fixed to one side of the sliding ring 24 close to the center of the support ring 19, and the welding gun 20 is fixedly mounted on the telescopic end of the electric telescopic rod 25. The welding gun 20 points to the axis of the support ring 19.

[0037] The driving assembly includes a second motor 26 and a friction wheel 27. A mounting block is fixedly connected to one side of the sliding ring 24, and the second motor 26 is fixed on the mounting block. The friction wheel 27 is coaxially fixedly connected to the motor shaft of the second motor 26, and the axis of the friction wheel 27 is parallel to the axis of the support ring 19. The friction wheel 27 is in friction contact with the circumferential surface of the support ring 19. When the friction wheel 27 rotates, the friction wheel 27 rolls along the outer circumferential surface of the support ring 19, thereby causing the sliding ring 24 to slide along the circumferential surface of the support ring 19.

[0038] A lead screw 3 is rotatably connected between the two vertical plates 2, and a first motor 4 is fixedly mounted on one of the vertical plates 2, and the first motor 4 is drivingly connected to the lead screw 3. The screw threads on both sides of the lead screw 3 have opposite spiral directions.

[0039] A first limiting rod 6 is fixedly connected between the two vertical plates 2, and the axes of the first limiting rod 6, the lead screw 3 and the support ring 19 are parallel to each other. Two moving frames 5 are slidably sleeved on the first limiting rod 6. The two moving frames 5 are threadedly connected to both sides of the lead screw 3 respectively.

[0040] The movable frame 5 is provided with a waist-shaped hole 9. There are two clamps 13, which are symmetrically arranged about the support ring 19. The two clamps 13 correspond to the two movable frames 5 one by one. A slide plate 10 is fixedly connected to one side of each clamp 13, and a first slide bar 11 is fixedly connected to one end of the slide plate 10. The first slide bar 11 is slidably arranged in the corresponding waist-shaped hole 9. And the first slide bar 11 can rotate in the waist-shaped hole 9.

[0041] A second limiting rod 7 is fixedly connected between each vertical plate 2 and the support plate 8, and the two second limiting rods 7 are symmetrically arranged.

The second limiting rod 7 includes a first horizontal section, an arc section, a vertical section and a second horizontal section. One end of the first horizontal section is fixedly connected to the vertical plate 2. The first horizontal section, the arc section, the vertical section and the second horizontal section are fixedly connected in sequence. One end of the second horizontal section is fixedly connected to the support plate 8. The concave side of the arc section is arranged away from the support ring 19. The distance between the first horizontal section and the upper end surface of the base plate 1 is equal to the distance between the vertical section and the support ring 19.

[0042] The lower end of the clamp 13 is threadedly connected with a rotating cap 14. A friction strip 22 is fixedly mounted on the vertical plate 2, and the friction strip 22 is in friction contact with the rotating cap 14. When the clamp 13 moves along the first limiting rod 6, the rotating cap 14 rotates under the action of the friction strip 22.

[0043] Both ends of the chuck 13 have openings, and the lower end of the rotating cap 14 has a through hole. A grinding plate 21 that cooperates with the grounding body 23 is fixedly arranged on the upper end surface of the bottom plate 1. When in use, the grounding body 23 is placed in the chuck 13, and one end of the grounding body 23 passes through the rotating cap 14 and extends to the upper end surface of the bottom plate 1 and contacts the grinding plate 21. When the chuck 13 drives the grounding body 23 to move, one end of the grounding body 23 moves along the grinding plate 21, and the grinding plate 21 grinds the end of the grounding body 23.

[0044] A clamping assembly for fixing the grounding body 23 is arranged in the clamping barrel 13. The clamping assembly includes a clamping plate 17 and a second sliding rod 18.

[0045] A plurality of oblique holes 15 are formed on the bottom wall of the rotating cap 14. The plurality of oblique holes 15 are evenly distributed along the axis of the rotating cap 14.

[0046] A pull rod 16 is slidably arranged in each inclined hole 15, and each pull rod 16 is fixedly connected to a clamping plate 17, which is arranged vertically. The upper end of the clamping plate 17 extends into the clamping barrel 13. The side of the clamping plate 17 facing the axis of the rotating cap 14 is arc-shaped. A plurality of second slide rods 18 are fixedly connected to the side of each clamping plate 17 that is away from the axis of the rotating cap 14. The end of the second slide rod 18 that is away from the clamping plate 17 slides through the side wall of the clamping barrel 13 and then extends to the outside. The second slide rod 18 is arranged along the radial direction of the clamping barrel 13.

[0047] Working principle: Initially, the two clamps 13 are located at the two ends of the screw 3 respectively.

[0048] When in use, the grounding body 23 is inserted into the clamp 13 , with the end of the grounding body 23 to be welded facing downward, and the lower end of the grounding body 23 abuts against the polishing plate 21 .

[0049] Then, the first motor 4 is started, the moving frame 5 moves along the first limiting rod 6 toward the middle of the first limiting rod 6 , the moving frame 5 drives the slide plate 10 to move, the slide plate 10 moves along the first horizontal section of the second limiting rod 7 , and the slide plate 10 drives the clamp 13 to move.

[0050] When the slide plate 10 moves along the first horizontal section, the rotating cap 14 moves along the friction strip 22, and under the action of the friction strip 22, the rotating cap 14 rotates. The rotating cap 14 drives the clamping plate 17 to rotate. The pull rod 16 slides in the inclined hole 15, and under the guidance of the inclined hole 15, the clamping plate 17 moves toward the direction close to the axis of the clamping tube 13, so that the clamping plate 17 contacts the grounding body 23, and multiple clamping plates 17 clamp and fix the grounding body 23. At the same time, as the rotating cap 14 rotates, the rotating cap 14 is fastened to the clamping tube 13. At the same time, the lower end of the grounding body 23 moves along the grinding plate 21, and the grinding plate 21 grinds the grounding body 23, so that the oxide layer and other impurities on the surface of one end of the grounding body 23 that needs to be welded are ground off, which helps to improve the welding quality.

[0051] As the moving frame 5 moves, when the slide plate 10 moves along the arc section of the second limiting rod 7, the slide plate 10 moves upward along the waist-shaped hole 9. Fig. 9 , Fig.10 , Fig.11 As shown, under the guidance of the arc segment, the grounding body 23 moves upward and moves toward the direction close to the support ring 19, the grounding body 23 gradually tilts, and the grounding body 23 gradually changes to a horizontal state. When the slide plate 10 moves to the lower end of the vertical section through the arc segment, the grounding body 23 is in a horizontal state, and at this time, the end of the grounding body 23 to be welded extends into the support ring 19 and the two grounding bodies 23 are butt-jointed, and at this time, the welding gun 20 points to the butt joint of the two grounding bodies 23. Make the axis of the grounding body 23 and the axis of the support ring 19 on the same straight line, and stop the first motor 4.

[0052] Then the electric telescopic rod 25 is started to move the welding gun 20 closer to the grounding body 23. Then the second motor 26 is started to move the sliding ring 24 along the circumferential surface of the support ring 19, so that the welding gun 20 welds one circle of the grounding body 23.

[0053] After welding is completed, the rotating cap 14 is rotated in the opposite direction, and the clamping plate 17 moves away from the axis of the rotating cap 14, so that the clamping assembly releases the clamping of the grounding body 23, and then the welded grounding body 23 can be taken out. After that, the first motor 4 is started to reset the two clamping barrels 13 to prepare for the next welding.

[0054] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
