[0037] Embodiment: Please refer to Figures 1-8 , a welding device for assembling a gearbox solenoid valve group, including a base 1. A guide rail 11 is provided at the upper end of the base 1, and a pre-fixing component 2 is slidably installed on the outer surface of the guide rail 11 to preliminarily limit the components through the pre-fixing component 2.

[0038] In this solution, an electric telescopic rod is arranged on one side of the base 1, and the end of the electric telescopic rod is connected to the end of the pre-fixing component 2. Thus, the pre-fixing component 2 can be driven by the electric telescopic rod to move on the guide rail 11 until it stops at the optimal position.

[0039] Meanwhile, a welding component 12 is arranged on one side of the base 1. The welding component 12 consists of a manipulator and a welding gun, and the welded parts after the assembly of the transmission solenoid valve group are welded by the welding component 12.

[0040] Furthermore, the pre-fixing component 2 includes a bottom plate 21 slidably connected to the guide rail 11. A driving component 22 is fixedly installed at the middle position of the end of the bottom plate 21, and a driving disc 23 is fixedly installed at the output end of the driving component 22.

[0041] In this embodiment, the driving component 22 is a device with power output such as a motor and is connected to an external control device. When the driving component 22 is started, the driving disc 23 fixedly installed at its output end is synchronously driven to rotate.

[0042] An activity groove that fits the guide rail 11 is opened at the lower end of the bottom plate 21, so that the whole remains stable when the bottom plate 21 moves.

[0043] Two identical components are symmetrically distributed in the pre-fixing component 2. An electric telescopic rod is arranged at the lower end of one of the components, and the height of one of the components is adjusted by the electric telescopic rod to make it suitable for different scenarios.

[0044] Furthermore, fixing rings 24 are fixedly installed at both ends of the end of the bottom plate 21. A transmission ring 25 is slidably installed on the inner wall of the fixing ring 24, and the outer surface of the transmission ring 25 meshes with the outer surface of the driving disc 23.

[0045] Specifically, an annular groove is opened on the inner wall of the fixing ring 24, and the inner wall of the annular groove is slidably connected to the outer surface of the transmission ring 25. Since the outer surface of the transmission ring 25 meshes with the outer surface of the driving disc 23, when the driving disc 23 rotates, the transmission ring 25 is synchronously driven to move along the inner wall of the annular groove until it stops at the optimal position.

[0046] A slot hole is opened on the outer surface of the fixing ring 24 and near one end of the driving component 22, which facilitates the meshing of the driving disc 23 and the transmission ring 25.

[0047] Furthermore, a limiting rod 26 is fixedly installed inside the transmission ring 25. A support plate 261 is fixedly installed at the end of the limiting rod 26. A fixing plate 27 is fixedly installed at the end of the support plate 261. A clamping block 271 is rotatably installed on one side of the fixing plate 27. A positioning rod 272 is rotatably installed at the end of the clamping block 271, and the end of the positioning rod 272 is rotatably connected to one side of the fixing plate 27.

[0048] Specifically, when the transmission ring 25 is subjected to force and rotates, it synchronously drives the limit rod 26 to rotate, thereby adjusting the position of the support plate 261 to make it suitable for the current scenario.

[0049] A chute is formed on one side of the positioning rod 272, and a clamping rod is slidably installed on the inner wall of the chute. The clamping rod is connected to the fixing plate 27, so that when the clamping block 271 and the positioning rod 272 are subjected to force, they move along the inner wall of the through hole 273 until they reach the optimal position.

[0050] Meanwhile, a torsion spring is arranged at the connection between the positioning rod 272 and the clamping block 271, so that when the positioning rod 272 and the clamping block 271 stop being subjected to force, the positioning rod 272 and the clamping block 271 are restored to the initial position by the acting force of the torsion spring.

[0051] Furthermore, a through hole 273 is formed on one side of the fixing plate 27. The inner wall of the through hole 273 is slidably connected to the outer surface of the connection between the clamping block 271 and the positioning rod 272. A limiting block 28 is rotatably installed at the connection between the clamping block 271 and the positioning rod 272, and an arc-shaped block 281 is rotatably installed at the end of the limiting block 28.

[0052] Specifically, when the solenoid valve component is placed on the arc-shaped block 281, the rotationally installed limiting block 28 drives the connection between the clamping block 271 and the positioning rod 272 to move along the inner wall of the through hole 273, thereby supporting the solenoid valve component. At the same time, it cooperates with the other arc-shaped block 281 to rotate along the inner wall of the fixed ring 24, so that the two arc-shaped blocks 281 are symmetrically distributed and the solenoid valve component is preliminarily fixed, which is convenient for fine adjustment during docking. When the arc-shaped block 281 rotates, it moves along the outer surface of the solenoid valve component, thereby preliminarily correcting the solenoid valve component and synchronously detecting the outer surface of the solenoid valve component to ensure the integrity of the solenoid valve component.

[0053] Furthermore, a locking assembly 3 is assembled on the outer surface of the guide rail 11 to tightly lock the components after docking in cooperation with the pre-fixing assembly 2; the locking assembly 3 includes a moving plate 31 slidably connected to the guide rail 11. A power member 32 is arranged at the middle position of the end of the moving plate 31, and a power gear 33 is fixedly installed at the output end of the power member 32.

[0054] In this embodiment, the power member 32 is a device with power output such as a motor and is connected to an external control device. When the power member 32 is started, it synchronously drives the power gear 33 arranged at its output end to rotate.

[0055] A moving groove is provided at the lower end of the moving plate 31, and the inner wall of the moving groove is slidably connected to the outer surface of the guide rail 11. At the same time, a device with a telescopic function such as an electric telescopic rod is provided on one side of the moving plate 31, and the end of the electric telescopic rod is fixedly connected to the end of the base 1. The moving plate 31 is driven to move by the electric telescopic rod.

[0056] Furthermore, a protective rod 34 is fixedly installed at the end of the power gear 33, and swing rods 341 are rotatably installed at both ends of the protective rod 34. A first gear 331 is rotatably installed at the connection between the protective rod 34 and the swing rod 341, and the outer surface of the first gear 331 is meshed with the outer surface of the power gear 33; a second gear 332 is rotatably installed at the end of the swing rod 341 away from the protective rod 34, and the outer surface of the second gear 332 is meshed with the outer surface of the first gear 331.

[0057] Specifically, when the power gear 33 rotates, it synchronously drives the protective rod 34 fixedly installed at its end to rotate. Since swing rods 341 are rotatably installed at both ends of the protective rod 34, a protective groove is provided at the end of the moving plate 31, and the inner wall of the protective groove is slidably connected to the end of the swing rod 341. Therefore, when the protective rod 34 rotates, it drives the two swing rods 341 to slide along the inner wall of the protective groove to both sides.

[0058] At the same time, when the power gear 33 rotates, it synchronously drives the first gear 331 meshed with its outer surface to rotate. Since the outer surface of the first gear 331 is meshed with the outer surface of the second gear 332, it drives the second gear 332 to rotate. When the second gear 332 rotates, it drives the power rod 35 fixedly installed at its end to rotate.

[0059] Furthermore, a positioning plate 36 is fixedly installed at the upper end of the moving plate 31, and a guide groove 361 is provided at the end of the positioning plate 36. A guide block 362 is slidably installed on the inner wall of the guide groove 361. A power rod 35 is fixedly installed at the end of the second gear 332, and the end of the power rod 35 penetrates and extends to the other end of the guide block 362.

[0060] Specifically, when the power rod 35 moves following the second gear 332, when the power rod 35 moves, it synchronously drives the guide block 362 rotatably installed on the outer surface of the power rod 35 to move. The outer surface of the guide block 362 is slidably connected to the inner wall of the guide groove 361. Therefore, when the power rod 35 moves, it drives the guide block 362 to move along the inner wall of the guide groove 361, so that the two guide blocks 362 move closer to the middle or expand to both ends synchronously.

[0061] Further, a support block 37 is fixedly installed at the end of the guiding block 362. A first rotating shaft 371 is rotatably installed on the inner wall of the support block 37 close to the guiding block 362. The end of the first rotating shaft 371 is fixedly connected to the end of the power rod 35. A second rotating shaft 372 is rotatably installed on the inner wall of the support block 37 away from the guiding block 362. The cross-section of the second rotating shaft 372 is perpendicular to that of the first rotating shaft 371. A transmission block 38 is rotatably installed between the first rotating shaft 371 and the second rotating shaft 372.

[0062] Specifically, when the power rod 35 rotates, it synchronously drives the first rotating shaft 371 fixedly installed at its end to rotate. And when the first rotating shaft 371 rotates, it drives the transmission block 38 to rotate. Since the end of the transmission block 38 is rotatably connected to the end of the second rotating shaft 372, the second rotating shaft 372 is synchronously driven to rotate.

[0063] A rubber plate is arranged at the end of the second rotating shaft 372. When the second rotating shaft 372 rotates, it drives the rubber plate to lock the solenoid valve component, ensuring the stability of the welding end, making the weld seam uniform, and reducing welding defects such as cracks, pores, and false soldering, thereby improving the overall quality of the solenoid valve.

[0064] Further, a protection block 39 is fixedly installed at the end of the guiding block 362, and a clamping block 391 is slidably installed at the end of the protection block 39.

[0065] Specifically, when the guiding block 362 moves, it drives the protection block 39 to move. At the same time, devices with telescopic functions such as electric telescopic rods are arranged at the end of the protection block 39. The electric telescopic rod is used to drive the clamping block 391 to move, thereby performing secondary locking on the solenoid valve component and ensuring the stability during welding.

[0066] The control device can select a single-chip microcomputer as the control terminal. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Micro controller Unit), which is composed of an arithmetic unit, a controller, a memory, input and output devices, etc., and is equivalent to a miniature computer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes more on self-supply (without external hardware) and cost savings. Its greatest advantage is its small size, which can be placed inside the instrument, but it has a small storage capacity, simple input and output interfaces, and low power consumption.

[0067] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
