Description

Technical Field

[0001] This invention relates to the field of robot assembly technology, and in particular to a welding device for robot assembly processing. Background Technology

[0002] The application of industrial robots in manufacturing is becoming increasingly widespread, placing higher demands on the precision, stability, and flexibility of welding fixtures during the manufacturing process. Traditional welding fixtures mostly adopt fixed structures, which are difficult to adapt to the clamping requirements of workpieces of different specifications or irregular shapes, resulting in unstable welding quality.

[0003] A search revealed Chinese patent application CN221639967U, which discloses a welding fixture for industrial robot manufacturing. By installing a main body mechanism, when using this welding fixture for welding operations on an industrial robot, the operator can move two sets of grippers up and down to adjust the two sets of industrial robot components separately. However, this device still has shortcomings in application. Manual adjustment of the fixture is inefficient and prone to affecting welding accuracy due to operational errors. There is an urgent need to invent a welding device for robot assembly and processing to solve these problems, proposing an automated and modular solution to improve production efficiency and consistency.

The movable clamping plate is fixedly connected to the rod body of the telescopic rod. A guide slope adapted to the guide cone is opened at the bottom of the pin.

[0006] Preferably, a support plate is fixedly connected to the top of the slide rail at the end away from the motor, and one end of the drive screw is rotatably connected to the side of the support plate.

[0007] Preferably, the telescopic rod has a sliding groove on its side, a limit frame is fixedly connected to the side of the fixed clamping piece near the moving clamping piece, a return spring is located inside the limit frame, and a slider is fixedly connected to the end of the limit frame away from the fixed clamping piece, and the slider is slidably connected inside the sliding groove.

[0008] Preferably, a handle is fixedly connected to the end of the telescopic rod away from the guide cone, and a retaining ring is fixedly connected to the rod body of the telescopic rod, with one side of the retaining ring contacting the outer wall of the support leg.

[0009] Preferably, a fixed shaft seat is fixedly connected to the top of the connector, an adjusting screw is rotatably connected to one side of the fixed shaft seat, a limit strip is fixedly connected to the top of the connector, a movable shaft seat is slidably connected to the top of the limit strip, the movable shaft seat is threadedly connected to the rod body of the adjusting screw, and a rotating handle is fixedly connected to the end of the adjusting screw away from the fixed shaft seat.

[0010] Preferably, the bottom end of the pneumatic telescopic cylinder is located between the moving shaft seat and the fixed shaft seat, and the adjusting screw is inserted into the bottom end of the pneumatic telescopic cylinder.

[0011] Preferably, a gasket is fixedly connected to the side of the fixed shaft seat and the moving shaft seat that are close to each other.

[0012] Preferably, the end of the slide rail away from the motor is configured as a retaining ring, and a gripper is hinged to one side of the retaining ring. One end of the gripper is fixedly connected to the retaining ring by a fastening bolt, and the top of the pneumatic telescopic cylinder is clamped between the retaining ring and the gripper.

[0013] Preferably, a slot is provided on one side of the workbench, a sleeve is slidably connected inside the slot, a handle is fixedly connected to the middle of one side of the sleeve, the shell of the sleeve has evenly distributed slag leakage holes, a core plate is inserted into the inside of the sleeve, one end of the core plate is hinged to the inner wall of the slot, and a recycling trough adapted to the core plate is fixedly connected between two legs near the slot.

[0014] Preferably, the outer walls on both sides of the housing are rotatably connected to evenly distributed rollers. The slot walls on both sides of the slot are provided with wheel grooves, and the rollers on both sides of the housing are respectively inserted into the two wheel grooves.

[0015] Compared with the prior art, the present invention provides a welding device for robotic assembly and processing, which has the following beneficial effects: 1. This welding equipment for robotic assembly and processing, through modular design including a pin, extension arm, motor, drive screw, guide cone, return spring, and telescopic rod, enables rapid assembly and disassembly of the welding equipment. It allows for flexible adjustment of the clamping pad and welding torch position according to welding requirements. The cooperation between the guide cone and return spring enables automatic pin positioning, simplifying the operation process. Simultaneously, the pneumatic telescopic cylinder and motor-driven slide rail system precisely control the welding angle and position, improving automation. Furthermore, the inclined surface design of the pin and guide cone ensures self-alignment during assembly, reducing manual intervention and improving efficiency.

[0016] 2. This welding equipment for robot assembly and processing includes an adjusting screw, a moving shaft seat, a fixed shaft seat, and shims. Rotating the adjusting screw with a handle allows for adjustment of the distance between the fixed and moving shaft seats via a threaded connection. A limiting strip restricts the movement of the moving shaft seat, preventing axial deflection. When the moving shaft seat is close to the fixed shaft seat and clamps the pneumatic telescopic cylinder, the connecting part cannot rotate. When the moving shaft seat is away from the fixed shaft seat, the connecting part can rotate, facilitating adjustment of the angles of the clamping pad and the welding torch. When the fixed and moving shaft seats clamp the pneumatic telescopic cylinder together, the shims act as a buffer, preventing mutual wear between the fixed and moving shaft seats and the pneumatic telescopic cylinder. Furthermore, adjusting the pressure of the fixed and moving shaft seats on the shims allows for damped rotation between the pneumatic telescopic cylinder and the connecting part, further optimizing the ease of operation of the device.

[0017] 3. This welding equipment for robot assembly and processing includes a recovery tank, a core plate, a casing, slag leakage holes, and rollers. Before welding, the core plate is fully inserted into the casing to enhance its strength and facilitate support for components placed on top. Welding slag generated during welding reaches the top of the core plate through the slag leakage holes on the top of the casing. After welding, the core plate is pulled out from the casing by pulling the casing with a handle. During this process, the welding slag moves synchronously under the push of the inner wall of the slag leakage holes. When it passes the edge of the core plate, the upper and lower welding slag holes are connected, and the welding slag falls downward into the recovery tank. When the core plate is completely pulled out, one end loses support and flips downward. The bottom of the slope formed after the core plate flips extends into the recovery tank, guiding the remaining welding slag into the recovery tank. The rollers, in conjunction with the grooves, support the casing in the slots. Because the rollers can roll, the movement resistance of the casing is greatly reduced, making the pulling operation of the casing easier. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Reference Figure 1-8A welding device for robot assembly includes a worktable 1 and four legs 2. The four legs 2 are fixed to the four corners of the bottom of the worktable 1. Each corner of the worktable 1 has a pin hole 14. At least two pin holes 14 are fitted with pins 3. A counterweight 5 is fixedly connected to the top of the pin 3. The counterweight 5 is located on the top of the worktable 1. An extension arm 6 is rotatably connected to the top of the counterweight 5. A sliding sleeve 7 is fixedly connected to the top of the extension arm 6. A slide rail 8 is slidably connected inside the sliding sleeve 7. A motor 10 is fixedly connected to one end of the top of the slide rail 8. A drive screw 11 is driven to the output end of the motor 10. A threaded sleeve 12 is fixedly connected to the top of the sliding sleeve 7. The drive screw 11 is threaded into the inside of the threaded sleeve 12. A pneumatic telescopic cylinder 9 is fixedly connected to one end of the slide rail 8. The bottom of the pneumatic telescopic cylinder 9 is rotatably connected to a connector 21. One of the connectors 21 is fixedly connected to a welding torch 22 on its side. The bottom of the other connectors 21 is clamped with a clamping pad 23. The bottom of the pin 3 is horizontally provided with a positioning hole 4. A guide cone 25 is inserted into the positioning hole 4. A telescopic rod 24 is fixedly connected to one side of the guide cone 25. The telescopic rod 24 is slidably connected to the top of the support leg 2. A fixed clamping piece 33 is fixedly connected to the inner wall of the support leg 2. The fixed clamping piece 33 is slidably connected to the rod body of the telescopic rod 24. A return spring 28 is fixedly connected to the side of the fixed clamping piece 33. A movable clamping piece 37 is fixedly connected to the end of the return spring 28 away from the fixed clamping piece 33. The movable clamping piece 37 is fixedly connected to the rod body of the telescopic rod 24. The bottom of the pin 3 is provided with a guide slope 30 adapted to the guide cone 25.

[0022] In use, the workbench 1 is supported by the support legs 2. During welding, the part to be welded by the robot is placed on top of the workbench 1 and then clamped. During clamping, the extension arm 6 is rotated, and then the drive screw 11 is driven to rotate by the motor 10. The slide rail 8 moves laterally along the inner wall of the slide sleeve 7 under the cooperation of the drive screw 11 and the threaded sleeve 12. After the position of the clamping pad 23 is adjusted, the pneumatic telescopic cylinder 9 pulls the connector 21 and the clamping pad 23 downward, so that the clamping pad 23 presses against the surface of the part to be welded, thus completing the pre-welding clamping. Then, the part is welded by the welding torch 22. The initial position of the welding torch 22 can also be adjusted by the extension arm 6, the motor 10 and the pneumatic telescopic cylinder 9. At the same time, the motor 10 and the pneumatic telescopic cylinder 9 can drive the welding torch 22 to move, thereby realizing automatic welding of parts at different positions and angles. The guide cone 25 is inserted. The positioning hole 4 of the pin 3 enables the positioning of the pin 3 and the counterweight 5. Pulling the telescopic rod 24 pulls the guide cone 25 out of the positioning hole 4, thus releasing the positioning of the pin 3. At this time, the counterweight 5 can be lifted, allowing the pin 3 to be pulled out of the pin hole 14, thereby removing the clamping pad 23 and the welding torch 22 from the top of the workbench 1. When reinstallation is required, the pin 3 is inserted into the pin hole 14. Under the pressure of the counterweight 5, the guide slope 30 pushes the guide cone 25 and the telescopic rod 24 towards one side of the pin 3, while compressing the return spring 28. When the pin 3 descends to the lower limit, the guide cone 25 aligns with the positioning hole 4, and the return spring 28 pushes the guide cone 25 into the positioning hole 4 through its elasticity, ensuring self-alignment during assembly, reducing manual intervention, and allowing operators to freely adjust the number and position of the clamping pad 23 or the welding torch 22 according to different welding requirements.

[0023] In this invention, a support plate 13 is fixedly connected to the top of the slide rail 8 at the end away from the motor 10, and one end of the drive screw 11 is rotatably connected to the side of the support plate 13. By rotatably connecting the end of the drive screw 11 away from the motor 10 to the support plate 13, the support and reinforcement of the drive screw 11 are achieved, thereby optimizing the stability and service life of the drive screw 11.

[0024] In this invention, a groove 36 is provided on the side of the telescopic rod 24. A limit frame 34 is fixedly connected to the side of the fixed clamp 33 near the moving clamp 37. The return spring 28 is located inside the limit frame 34. A slider 35 is fixedly connected to the end of the limit frame 34 away from the fixed clamp 33. The slider 35 is slidably connected inside the groove 36. When the telescopic rod 24 is pulled, the fixed clamp 33 and the moving clamp 37 jointly compress the return spring 28, and the slider 35 slides along the inside of the groove 36 to limit the extension and retraction stroke of the return spring 28.

[0025] In this invention, a handle 27 is fixedly connected to the end of the telescopic rod 24 away from the guide cone 25, and a retaining ring 32 is fixedly connected to the rod body of the telescopic rod 24. One side of the retaining ring 32 contacts the outer wall of the support leg 2. When the telescopic rod 24 is pulled by the handle 27, the retaining ring 32 cooperates with the support leg 2 to limit the depth of the telescopic rod 24 inserted into the support leg 2, thereby limiting the position of the guide cone 25.

[0026] In this invention, a fixed shaft seat 43 is fixedly connected to the top of the connector 21, an adjusting screw 38 is rotatably connected to one side of the fixed shaft seat 43, a limiting strip 40 is fixedly connected to the top of the connector 21, a movable shaft seat 41 is slidably connected to the top of the limiting strip 40, the movable shaft seat 41 is threadedly connected to the rod of the adjusting screw 38, and a handle 39 is fixedly connected to the end of the adjusting screw 38 away from the fixed shaft seat 43. By rotating the adjusting screw 38 through the handle 39, the distance between the fixed shaft seat 43 and the movable shaft seat 41 can be adjusted under the threaded engagement. The limiting strip 40 limits the movement of the movable shaft seat 41 to prevent axial deflection of the movable shaft seat 41.

[0027] In this invention, the bottom end of the pneumatic telescopic cylinder 9 is located between the moving shaft seat 41 and the fixed shaft seat 43. The adjusting screw 38 is inserted into the bottom end of the pneumatic telescopic cylinder 9. The position of the moving shaft seat 41 is adjusted by adjusting the adjusting screw 38. When the moving shaft seat 41 is close to the fixed shaft seat 43 and clamps the pneumatic telescopic cylinder 9, the connecting piece 21 cannot rotate. When the moving shaft seat 41 is away from the fixed shaft seat 43, the connecting piece 21 can be rotated, which facilitates the adjustment of the angle of the clamping pad 23 and the welding torch 22.

[0028] In this invention, a gasket 42 is fixedly connected to the side of the fixed shaft seat 43 and the moving shaft seat 41 that are close to each other. When the fixed shaft seat 43 and the moving shaft seat 41 clamp the pneumatic telescopic cylinder 9 together, the gasket 42 can play a buffering role to prevent the fixed shaft seat 43, the moving shaft seat 41 and the pneumatic telescopic cylinder 9 from wearing each other. At the same time, by adjusting the pressure of the fixed shaft seat 43 and the moving shaft seat 41 on the gasket 42, the pneumatic telescopic cylinder 9 and the connecting member 21 can achieve damped rotation, further optimizing the ease of operation of the device.

[0029] In this invention, the end of the slide rail 8 away from the motor 10 is configured as a retaining ring, and a clamping claw 31 is hinged to one side of the retaining ring. One end of the clamping claw 31 is fixedly connected to the retaining ring by a fastening bolt. The top of the pneumatic telescopic cylinder 9 is clamped between the retaining ring and the clamping claw 31. The pneumatic telescopic cylinder 9 is clamped by the retaining ring and the clamping claw 31 at the end of the slide rail 8. After removing the fastening bolt connecting the retaining ring and the clamping claw 31, the clamping claw 31 can be rotated, making the installation, disassembly and maintenance of the pneumatic telescopic cylinder 9 more convenient.

[0030] In this invention, a slot 26 is provided on one side of the workbench 1, and a sleeve 17 is slidably connected inside the slot 26. A handle 18 is fixedly connected to the middle of one side of the sleeve 17. The shell of the sleeve 17 has evenly distributed slag leakage holes 20. A core plate 15 is inserted into the inside of the sleeve 17. One end of the core plate 15 is hinged to the inner wall of the slot 26. A recycling groove 16 adapted to the core plate 15 is fixedly connected between two support legs 2 near the slot 26. Before welding, the core plate 15 is fully inserted into the inside of the sleeve 17, thereby enhancing the strength of the sleeve 17 and facilitating the support of the components placed above. The welding slag generated during the welding process reaches the top of the core plate 15 through the slag leakage hole 20 above the casing 17. After the welding operation is completed, the core plate 15 is pulled out from the inside of the casing 17 by pulling the casing 17 with the handle 18. During this process, the welding slag moves synchronously under the push of the inner wall of the slag leakage hole 20. When it passes the edge of the core plate 15, the upper and lower welding slag holes 20 are connected, and the welding slag can fall down into the recycling tank 16. When the core plate 15 is completely pulled out, one end of it loses support and flips downward. The bottom of the slope formed after the core plate 15 flips extends into the recycling tank 16, guiding the remaining welding slag into the recycling tank 16.

[0031] In this invention, the outer walls on both sides of the casing 17 are rotatably connected with evenly distributed rollers 19. The groove walls on both sides of the slot 26 are provided with wheel grooves 29. The rollers 19 on both sides of the casing 17 are respectively inserted into the two wheel grooves 29. The rollers 19 cooperate with the wheel grooves 29 to support the casing 17 in the slot 26. Since the rollers 19 can roll, the moving resistance of the casing 17 is greatly reduced, making the pulling operation of the casing 17 easier.

[0032] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
