Description

Technical Field

[0001] This invention relates to the field of sprocket processing technology, specifically a welding machine for improving the sprocket welding qualification rate. Background Technology

[0002] In the sprocket manufacturing industry, welding is typically used to connect the sprocket teeth and hub of non-standard sprockets. This method is cost-effective and meets market demand. The welding process involves first placing the sprocket teeth on a welding platform, ensuring they are stable and accurately positioned. Then, the hub is placed on top of the sprocket teeth, ensuring accurate and stable positioning. Finally, manual welding is performed vertically to ensure a secure connection between the sprocket teeth and hub. This method reduces manufacturing costs while meeting market demands and improving welding quality and efficiency. However, because it is manual welding, the skill and experience of the operators significantly impact welding quality. Therefore, professional training and management of operators are usually necessary to improve welding quality and efficiency. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a welding machine that improves the pass rate of sprocket welding. It solves the problem that existing non-standard sprocket welding processes rely on manual welding, making the operator's skills and experience significantly impact welding quality. Improving welding quality and efficiency typically requires professional training and management of operators.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a welding machine for improving the sprocket welding qualification rate, comprising a machine body, a welding structure, a servo motor, a first cylinder, and a second cylinder. A fixed plate is provided on the top of the machine body. The welding structure is fixedly connected to the bottom of the fixed plate. Two connecting plates are fixedly connected to the inner bottom wall of the machine body. The servo motor is fixedly connected to the side wall of one of the connecting plates. Two fixed frames are provided between the two connecting plates. Drive rods are fixedly connected to the side walls of both fixed frames near the connecting plates. The drive end of the servo motor is fixedly connected to one of the drive rods. Two placement plates are provided between the two connecting plates. The two ends of the placement plates are respectively located inside the two fixed frames. Rotary handles are provided above and below each fixed frame. Lead screws are fixedly connected to the rotating handles near the outer surface of each fixed frame. The lead screws are threaded through the top of the fixed frame and extend into the interior of the fixed frame. The end of the lead screw away from the rotating handle is fixedly connected to the placement plate. A circular groove is opened through the top of the placement plate. Permanent magnet plates are provided on both sides of the placement plate. The permanent magnet plates are located inside the fixed frame. Movable rods are fixedly connected to the side walls of the permanent magnet plates near the placement plate. The movable rods pass through the side walls of the placement plate and extend into the circular groove. A movable plate is fixedly connected to the end of the movable rod away from the permanent magnet plate. Two clamping plates are provided between the two movable plates. Two limiting rods are fixedly connected to the side walls of the clamping plates near the movable plates. The two limiting rods pass through the movable plates and are located above and below the movable rods, respectively. A first cylinder is fixedly connected to the side wall of the connecting plate near the fixed frame. A second cylinder is located below the first cylinder and is fixedly connected to the side wall of the connecting plate near the fixed frame. The first cylinder and the second cylinder are located above and below the drive rod, respectively. Push plates are fixedly connected to the movable ends of the first cylinder and the second cylinder.

[0005] Preferably, the sidewalls of the fixed frame near the connecting plate have two through slots, and the push plate is adapted to the slots.

[0006] Preferably, an electromagnet is provided inside the push plate.

[0007] Preferably, a connecting spring is sleeved on the outer surface of the limiting rod, and the two ends of the connecting spring are fixedly connected to the movable plate and the clamping plate, respectively.

[0008] Preferably, the end face of the clamping plate away from the movable plate is an arc surface.

[0009] Preferably, another drive rod is rotatably connected to another connecting plate.

[0010] Working Principle: During operation, the operator places the teeth of the non-standard sprocket to be welded between two placement plates. By rotating the handle, the placement plates on the lead screw move closer to the teeth, fixing them in place. The operator then places the hub of the non-standard sprocket into the circular groove on the placement plate. A second cylinder drives a push plate through a slot in the fixed frame to contact the permanent magnet plate, moving it closer to the hub. This clamps the sides of the hub with the moving rod. Meanwhile, the first cylinder drives the push plate to contact the permanent magnet plate, generating a magnetic field through the electromagnet on the push plate. The adsorption force allows the first cylinder to drive the permanent magnet plate to move away from the hub, thus moving the corresponding clamping plate away from the hub and preventing the clamping plate from blocking the welding point between the clamping plate and the hub. Since the teeth and hub of the non-standard sprocket to be welded are fixed relatively stably, the pass rate of sprocket welding is effectively improved. Furthermore, by fixing the teeth with the placement plate and clamping the hub with the clamping plate, the position of the sprocket is limited, so the sprocket can be positioned for welding. Then, the non-standard sprocket teeth and hub are welded together through the welding structure. After the sprocket is welded, the teeth are fixed by the placement plate, so that the servo motor can drive the drive rod to flip the sprocket, thus allowing the welding structure to weld both the upper and lower end faces of the sprocket.

[0011] This invention provides a welding machine for improving the pass rate of sprocket welding. It has the following beneficial effects: 1. This welding machine for improving the sprocket welding qualification rate uses a first cylinder and a second cylinder to drive a push plate to contact a permanent magnet plate. This causes the clamping plate corresponding to the first cylinder to move away from the hub, while the clamping plate corresponding to the second cylinder contacts the hub. This allows the clamping plate to clamp and fix the hub of the non-standard sprocket. The rotating handle drives the lead screw to move the placement plate linearly, allowing the two placement plates to fix the teeth of the non-standard sprocket. Therefore, the teeth and hub of the non-standard sprocket to be welded are fixed more stably, effectively improving the sprocket welding qualification rate. Furthermore, by fixing the teeth with the placement plate and clamping and fixing the hub with the clamping plate, the position of the sprocket is defined, thus enabling positioning welding of the sprocket.

[0012] 2. This welding machine, which improves the welding qualification rate of sprockets, fixes the toothed plates with a placement plate, so that the servo motor can drive the drive rod to flip the sprocket, thereby enabling the welding structure to weld on both the upper and lower end faces of the sprocket.

Two connecting plates 4 are fixedly connected to the inner bottom wall of the machine body 1. The servo motor 5 is fixedly connected to the side wall of one of the connecting plates 4. Two fixed frames 6 are provided between the two connecting plates 4. Drive rods 7 are fixedly connected to the side walls of the two fixed frames 6 near the connecting plates 4. The drive end of the servo motor 5 is fixedly connected to one of the drive rods 7. Two placement plates 8 are provided between the two connecting plates 4. The two ends of the two placement plates 8 are respectively located inside the two fixed frames 6. Rotating handles 14 are provided above and below the fixed frames 6. Lead screws 15 are fixedly connected to the rotating handles 14 near the outer surface of the fixed frames 6. The lead screws 15 are threaded through the top of the fixed frames 6 and extend into the interior of the fixed frames 6. The end of the lead screw 15 away from the rotating handle 14 is fixed to the placement plate 8. The top of the placement plate 8 has a circular groove 9. Permanent magnet plates 16 are located on both sides of the placement plate 8, inside the fixed frame 6. Movable rods 17 are fixedly connected to the side walls of the permanent magnet plates 16 near the placement plate 8. The movable rods 17 penetrate the side walls of the placement plate 8 and extend into the circular groove 9. A movable plate 18 is fixedly connected to the end of the movable rod 17 away from the permanent magnet plate 16. Two clamping plates 19 are provided between the two movable plates 18. The clamping plates 19 are fixedly connected to the side walls of the movable plates 18. Two limiting rods 20 are provided, both of which pass through the movable plate 18. The two limiting rods 20 are located above and below the movable rod 17, respectively. The first cylinder 11 is fixedly connected to the side wall of the connecting plate 4 near the fixed frame 6. The second cylinder 12 is located below the first cylinder 11 and is fixedly connected to the side wall of the connecting plate 4 near the fixed frame 6.

[0017] Two slots 10 are cut through the side wall of the fixed frame 6 near the connecting plate 4. The push plate 13 is adapted to the slot 10. The first cylinder 11 and the second cylinder 12 can drive the push plate 13 to pass through the slot 10 and contact the permanent magnet plate 16, so that the position of the clamping plate 19 can be adjusted by changing the position of the permanent magnet plate 16. An electromagnet is set inside the push plate 13, so that the push plate 13 can generate an attraction force on the permanent magnet plate 16, so that the push plate 13 can drive the permanent magnet plate 16 to move. The outer surface of the limiting rod 20 is fitted with a connecting spring 21. The two ends of the connecting spring 21 are fixedly connected to the movable plate 18 and the clamping plate 19, respectively. By compressing the connecting spring 21, the clamping plate 19 can press the hub of the sprocket, so that the clamping plate 19 can clamp and fix the hub. The end face of the clamping plate 19 away from the movable plate 18 is an arc surface. The arc surface of the clamping plate 19 has a better clamping and fixing effect on the hub. Another drive rod 7 is rotatably connected to another connecting plate 4, so that the servo motor 5 can drive the sprocket to rotate stably.
