[0002] Welding equipment for metal parts is a diverse category of metal welding equipment, including arc welding equipment (such as manual arc welding and gas shielded welding), resistance welding equipment (such as spot welding machines and seam welding machines), laser welding equipment, electron beam welding equipment, and ultrasonic metal welding machines. These devices achieve metal connections through different principles and have wide-ranging applications. In the automotive industry, they can be used for welding automotive wiring harnesses and body parts; in battery manufacturing, they can weld battery tabs; in the electronics industry, they are used for precision welding of wiring harnesses and wire terminations; in home appliance manufacturing, they can weld internal wiring harnesses and connectors; in the medical product field, they meet the connection requirements of medical device components; and in the new energy industry, they are suitable for welding batteries and solar panels.

[0003] The existing welding equipment cannot rotate after clamping and positioning, which means that when welding hexagonal steel, the steel needs to be disassembled and reassembled six times for welding because it involves welding six sides, which seriously affects the welding efficiency. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a welding device for metal parts, which effectively solves the problem that the existing welding device cannot rotate after clamping and positioning, which leads to the need to repeatedly disassemble and reassemble the hexagonal steel six times when welding six sides, thus seriously affecting the welding efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a welding device for metal parts, including a workbench, a support frame fixedly installed on the top of the workbench, a vertical electric push rod fixedly installed on the top of the support frame, the transmission end of the vertical electric push rod passing downward through the support frame and fixedly installed with an mounting strip, a groove opened on the lower surface of the mounting strip, a slider slidably installed inside the groove, a mounting seat fixedly installed at the bottom of the slider, a welding gun fixedly installed on one side of the mounting seat, and a horizontal electric push rod fixedly installed at one end of the mounting strip through the mounting frame, the transmission end of the horizontal electric push rod being fixedly connected to the mounting seat;

[0006] Movable plates are provided on both sides above the workbench. A hydraulic cylinder is fixedly installed on the side of the two movable plates that are close to each other. A clamping head is fixedly installed on the transmission end of the two hydraulic cylinders. A slide rod is fixedly installed on the upper and lower parts of the side of the two clamping heads that are far apart from each other. A sliding sleeve is fitted on the surface of the slide rod. The surface of the sliding sleeve is fixedly connected to the movable plate through a support rod. A servo motor is fixedly installed on one side of the bottom of the workbench through a support plate. A transmission component is provided at the output end of the servo motor. The transmission component is connected to the two movable plates. When the two movable plates rotate, they will drive the two clamping heads to rotate, thereby causing the two clamping heads to drive the hexagonal steel to rotate.

[0007] Preferably, the transmission assembly includes a driving bevel gear, which is fixedly installed at the output end of the servo motor. A driven bevel gear is meshed with the upper part of the surface of the driving bevel gear. A rotating shaft is fixedly installed on the upper part of the driven bevel gear. The surface of the rotating shaft is rotatably connected to the bottom of the worktable through a bearing. A threaded rod is fixedly installed at the top of the rotating shaft. The top of the threaded rod is rotatably connected to the inner top of the worktable.

[0008] Preferably, the threaded rod is threadedly connected to a threaded sleeve, and racks are fixedly installed on both sides of the threaded sleeve by support arms. Sliding holes are opened at both ends of the upper surface of the worktable, and the two racks are slidably installed inside the two sliding holes.

[0009] Preferably, the upper end of one side of the rack is meshed with a transmission gear, the two transmission gears are rotatably connected to the two sides of the support frame through a positioning frame on the side away from each other, and the two transmission gears are fixedly installed with a shaft on the side close to each other. The surfaces of the two shafts are rotatably connected to the two sides of the support frame through bushings, and the two shafts are fixedly connected to the two movable plates at the ends close to each other.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the operator places two hexagonal steels to be welded onto the surfaces of two clamping heads, and then activates two hydraulic cylinders to push the two clamping heads to move towards each other. When the two clamping heads move, they both drive the sliding rod to slide inside the sliding sleeve, which increases the stability of the two clamping heads when they move. When the two clamping heads move towards each other, they clamp and fix the two hexagonal steels to be welded together. Then, the vertical electric push rod is activated to move the welding gun down to the joint of the hexagonal steels. Immediately afterwards, the horizontal electric push rod is activated to move the mounting base. When the mounting base moves, it drives the slider to slide inside the sliding groove, which improves the stability of the mounting base when it moves. When the mounting base moves laterally, it completes the welding of the joint of one side of the two hexagonal steels.

[0011] Subsequently, the operator activates the vertical electric push rod to move the welding torch upwards and reset it. Then, the servo motor is activated to drive the active bevel gear to rotate. The active bevel gear, through the driven bevel gear, drives the rotating shaft to rotate inside the bearing. As the shaft rotates, it drives the threaded sleeve upwards via the threaded rod. The upward movement of the threaded sleeve, in turn, drives the two racks upwards via the two support arms. The racks slide along the inside of the sliding hole, increasing their stability. Each upward movement of the racks pushes the transmission gear to rotate along the positioning frame. The rotation of the two transmission gears drives the shaft to rotate inside the bushing. The rotation of the shaft, through two moving plates and two hydraulic cylinders, drives the two clamping heads to rotate, thus rotating the hexagonal steel by 60°. This welding process is then repeated, rotating the hexagonal steel by 60° each time, until all six sides of the hexagonal steel are welded. This welding device allows the hexagonal steel to continue rotating even after being clamped and positioned, enabling quick and convenient welding of all six sides and significantly improving welding efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1 to 6 The present invention includes a workbench 1, a support frame 2 fixedly installed on the top of the workbench 1, a vertical electric push rod 3 fixedly installed on the top of the support frame 2, the transmission end of the vertical electric push rod 3 passing downward through the support frame 2 and fixedly installed with an installation strip 6, a groove 9 is provided on the lower surface of the installation strip 6, a slider 7 is slidably installed inside the groove 9, an installation seat 8 is fixedly installed at the bottom of the slider 7, a welding gun 4 is fixedly installed on one side of the installation seat 8, and a horizontal electric push rod 11 is fixedly installed at one end of the installation strip 6 through an installation frame 10, the transmission end of the horizontal electric push rod 11 is fixedly connected to the installation seat 8;

[0023] Movable plates 12 are provided on both sides above the workbench 1. Hydraulic cylinders 13 are fixedly installed on the side of the two movable plates 12 that are close to each other. Clamping heads 5 are fixedly installed on the transmission ends of the two hydraulic cylinders 13. Slide rods 14 are fixedly installed on the upper and lower parts of the side of the two clamping heads 5 that are far apart from each other. Slide sleeves 15 are fitted on the surface of the slide rods 14. The surface of the slide sleeves 15 is fixedly connected to the movable plates 12 through support rods 16. A servo motor 18 is fixedly installed on one side of the bottom of the workbench 1 through a support plate 17. A transmission assembly is provided at the output end of the servo motor 18. The transmission assembly is connected to the two movable plates 12. When the two movable plates 12 rotate, they will drive the two clamping heads 5 to rotate, thereby causing the two clamping heads 5 to drive the hexagonal steel to rotate.

[0024] In use, the operator places two hexagonal steels to be welded onto the surfaces of two clamping heads 5, and then activates two hydraulic cylinders 13 to push the two clamping heads 5 to move towards each other. When the two clamping heads 5 move, they both drive the slide rod 14 to slide inside the slide sleeve 15, which increases the stability of the two clamping heads 5 when they move. When the two clamping heads 5 move towards each other, they will clamp and fix the two hexagonal steels to be welded together. Then, the vertical electric push rod 3 is activated to move the welding gun 4 down to the joint of the hexagonal steels. Immediately afterwards, the horizontal electric push rod 11 is activated to move the mounting base 8. When the mounting base 8 moves, it drives the slider 7 to slide inside the slide groove 9, which improves the stability of the mounting base 8 when it moves. When the mounting base 8 moves laterally, it will complete the welding of the joint of one side of the two hexagonal steels.

[0025] Subsequently, the operator activates the vertical electric push rod 3 to move the welding torch 4 upward and reset it. Then, the servo motor 18 is activated to drive the transmission assembly. When the transmission assembly is running, it drives the two clamping heads 5 to rotate through the two moving plates 12 and the two hydraulic cylinders 13, thereby rotating the hexagonal steel by 60°. The above welding process is then repeated, rotating the hexagonal steel by 60° each time, until all six sides of the hexagonal steel are welded. This allows the welding device to continue rotating the hexagonal steel after it has been clamped and positioned, thus enabling the rapid and convenient welding of all six sides of the hexagonal steel and greatly improving welding efficiency.

[0026] The transmission assembly includes a drive bevel gear 19, which is fixedly mounted on the output end of the servo motor 18. A driven bevel gear 20 is meshed on the upper part of the surface of the drive bevel gear 19. A rotating shaft 21 is fixedly mounted on the upper part of the driven bevel gear 20. The surface of the rotating shaft 21 is rotatably connected to the bottom of the worktable 1 through a bearing 22. A threaded rod 23 is fixedly mounted on the top of the rotating shaft 21. The top of the threaded rod 23 is rotatably connected to the inner top of the worktable 1. A threaded sleeve 24 is threadedly connected to the surface of the threaded rod 23. A rack 26 is fixedly mounted on both sides of the threaded sleeve 24 through a support arm 25. Sliding holes 27 are opened at both ends of the upper surface of the worktable 1. The two racks 26 are slidably mounted inside the two sliding holes 27.

[0027] The servo motor 18 is started to drive the active bevel gear 19 to rotate. The active bevel gear 19 drives the rotating shaft 21 to rotate inside the bearing 22 through the driven bevel gear 20. When the rotating shaft 21 rotates, it drives the threaded sleeve 24 to move upward through the threaded rod 23. When the threaded sleeve 24 moves upward, it drives the two racks 26 to move upward through the two support arms 25. When the racks 26 move upward, they slide along the inside of the sliding hole 27, which increases the stability of the two racks 26 when they move.

[0028] The upper end of one side of the rack 26 is meshed with a transmission gear 28. The two transmission gears 28 are rotatably connected to the two sides of the support frame 2 through the positioning frame 29 on the side away from each other. The two transmission gears 28 are fixedly installed with shafts 30 on the side close to each other. The surfaces of the two shafts 30 are rotatably connected to the two sides of the support frame 2 through bushings 31. The two shafts 30 are fixedly connected to the two movable plates 12 respectively at the ends close to each other.

[0029] When the two racks 26 move upward, they both push the transmission gears 28 to rotate along the positioning frame 29. When the two transmission gears 28 rotate, they both drive the shaft 30 to rotate inside the bushing 31. When the shaft 30 rotates, it drives the two clamping heads 5 to rotate through the two moving plates 12 and the two hydraulic cylinders 13, thereby causing the hexagonal steel to rotate 60°. Then the above welding process is repeated, each time driving the hexagonal steel to rotate 60°, until all six sides of the hexagonal steel are welded.
