Description

Tooling for welding gas box plates for environmentally friendly gas cabinets Technical Field

[0001] The invention belongs to the technical field of welding devices, and more specifically, relates to a tool for welding gas box plates of environmentally friendly gas cabinets. Background Art

[0002] In industrial production, welding tooling is widely used in different fields such as shipbuilding, automobile manufacturing, aerospace, mechanical processing and home appliance manufacturing. The use of welding tooling can improve production efficiency, reduce production costs, and ensure welding quality and work safety. The tooling used for welding the gas tank plate of the environmental gas cabinet is specially designed for welding important structural components such as the gas tank plate in the environmental gas cabinet. The gas tank plate is an important structural component in the environmental gas cabinet and is used to seal the inside of the gas cabinet. Since the gas tank plate needs to withstand high pressure and impact during use, the welding process needs to be properly ensured. In order to ensure the welding quality of the gas tank plate and improve welding efficiency, special tooling is required.

[0003] However, during the implementation of the above technical solution, at least the following technical problems were found:

[0004] 1. When the welding tool is fixing the cabinet gas box plate, the welding equipment needs to perform multi-angle welding operations on the cabinet gas box plate. At this time, it is necessary to constantly adjust the angle position of the cabinet gas box plate and then re-clamp it with the welding tool, which makes the operation complicated and reduces the welding efficiency.

[0005] 2. A large number of sparks will fly during welding. These sparks are all metal debris particles. The flying sparks will adhere to the equipment. If they are not cleaned for a long time, they will cause corrosion and damage to the equipment, reducing the service life of the equipment.

[0006] 3. The flying sparks are basically melted metal particles. When the particles cool down, the sparks will solidify into solid particles and fix on the equipment, making the subsequent cleaning operation difficult. Summary of the Invention

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] In the present invention, a motor is provided, the motor is started, the motor drives the short rod 1 to rotate, the short rod 1 drives the driving gear to rotate synchronously, at this time the synchronous chain 1 drives the two driven gears to rotate, the two short rods 2 rotate synchronously with the rotation of the synchronous chain 1, the short rod 2 drives the rotating bevel gear to rotate, the rotating bevel gear drives the meshing bevel gear 1 to rotate, at this time the connecting tube and the driving gear 2 both start to rotate, the synchronous chain 2 drives the driven gear 2 and the connecting rod to rotate, and finally the purpose of rotating the fixture is achieved. When the fixture can drive the workpiece to be welded to rotate, the welding equipment can perform multi-faceted welding on it, avoiding the problem that the fixture cannot drive the workpiece to be welded to rotate and can only perform welding in a single position, resulting in the need to adjust the welding angle multiple times, simplifying the adjustment operation and improving the welding efficiency.

[0030] In the present invention, by providing a rubber cleaning brush, the rotation of the rotating bevel gear will drive the meshing bevel gear two to start rotating synchronously. At this time, the two meshing bevel gears two drive the two threaded rods to rotate. At this time, the moving block threaded on the threaded rod will drive the rubber cleaning brush to move in the tooling body, sweeping away the spark particles that were originally attached to the tooling body when flying, avoiding the flying sparks from adhering to the tooling body and causing corrosion and damage to it, thereby improving the service life of the equipment.

[0031] In the present invention, a rotating bevel gear is provided, and when the rotating bevel gear rotates, it will drive the meshing bevel gear one and the meshing bevel gear two to rotate synchronously, that is, the rotating fixture and the cleaning tool body are carried out synchronously. Since the rotating fixture represents that the welding device is in working state at this time, the flying sparks have just landed on the tool body. The flying sparks are hot when they are just generated, and it is easier to clean them at this time. When the sparks cool down, they will directly adhere to the tool body, and cleaning will be relatively difficult. When the welding work and the cleaning work are carried out at the same time, the convenience of the rubber cleaning brush in cleaning the flying metal particles is improved.

[0032] In the present invention, by providing a long rod, when the two threaded rods rotate to drive the moving block to rotate, the two long rods limit the moving block, so the moving block and the rubber cleaning brush do not rotate. At this time, the moving block will only move along the direction of the long rod, and no position deviation will occur, thereby improving the stability of the moving block when driving the rubber cleaning brush to clean.

[0033] In the present invention, a push plate is provided. When the moving block drives the rubber cleaning brush to move toward the position of the fixed block, it will first touch the push plate. At this time, the push plate squeezes the spring, and the spring can absorb part of the impact force brought by the movement of the moving block, thereby avoiding the moving block directly hitting the meshing bevel gear 2 and causing damage to the meshing bevel gear 2, thereby improving the service life of the meshing bevel gear 2.

[0034] In the present invention, a fixing ring is provided, which is directly connected to the tooling body. At this time, when the motor is started, the fixing ring will provide a stable output environment for the started motor, avoiding the continuous vibration of the motor itself during output that causes position deviation, thereby improving the stability of the motor when starting.

The fixing ring 14 is directly connected to the tool body 1. At this time, when the motor 13 is started, the fixing ring 14 will provide a stable output environment for the started motor 13, thereby avoiding the position deviation caused by the continuous vibration of the motor 13 itself during output, thereby improving the stability of the motor 13 when starting.

The two connecting blocks 4 are both internal hollow structures. The two clamps 3 are movably connected to the connecting blocks 4 at corresponding positions. A connecting rod 16 is provided inside the two connecting blocks 4, and the two connecting blocks 4 facing the clamp 3 are penetrated by a second hole 22. The two connecting rods 16 facing the clamp 3 pass through the second hole 22 and are fixedly connected to the clamp 3 at the corresponding position, and the two connecting rods 16 are rotatably connected to the inner wall of the connecting block 4 at the corresponding position on the side away from the clamp 3. When the two threaded rods 7 rotate to drive the moving block 25 to rotate, the two long rods 6 limit the moving block 25, so the moving block 25 and the rubber cleaning brush 26 do not rotate. At this time, the moving block 25 will only move along the direction of the long rod 6, and no position offset will occur, which improves the stability of the moving block 25 driving the rubber cleaning brush 26 to clean.

[0048] The lower surfaces of the two support columns 2 are fixedly connected to the fixing frames 18, and the two fixing frames 18 are fixedly connected to the tooling body 1. Holes 3 28 are provided at both ends of the two fixing frames 18. Connecting tubes 21 are provided inside the two fixing frames 18, and the two connecting tubes 21 are rotatably connected to the fixing frames 18 at the corresponding positions through the holes 3 28. The two connecting tubes 21 are movably connected to the threaded rods 7 at the corresponding positions. The connecting rod 16 on the left is fixedly connected to the driven gear 2 15, and the connecting tube 21 on the left is fixedly connected to the driving gear Wheel 2 19, the interior of the left support column 2 is provided with a synchronous chain 2 17, the upper end of the synchronous chain 2 17 is meshed with the driven gear 2 15, and the lower end of the synchronous chain 2 17 is meshed with the driving gear 2 19, the short rod 11 is fixedly connected to the driving gear 12, the interior of the tooling body 1 is provided with a synchronous chain 9, and the synchronous chain 9 is meshed with the driving gear 12, and the left and right ends of the driving gear 12 are provided with short rods 2 30, the lower surfaces of the two short rods 2 30 are rotatably connected to the tooling body 1, and the two Each short rod 2 30 is fixedly connected to a driven gear 1 31, and the two driven gears 1 31 are meshed with the synchronous chain 1 9. The upper surfaces of the two short rods 2 30 are fixedly connected to the rotating bevel gear 10. The motor 13 is started, and the motor 13 drives the short rod 11 to rotate, and the short rod 11 drives the driving gear to rotate synchronously. At this time, the synchronous chain 1 9 drives the two driven gears 1 31 to rotate, and the two short rods 2 30 rotate synchronously with the rotation of the synchronous chain 1 9, and the short rod 2 30 drives the rotating bevel gear 10 to rotate, and the rotating bevel gear 10 rotates. The gear 10 drives the meshing bevel gear 1 20 to rotate. At this time, the connecting cylinder 21 and the driving gear 2 19 both start to rotate, and the synchronous chain 2 17 drives the driven gear 2 15 and the connecting rod 16 to rotate, and finally achieves the purpose of rotating the clamp 3. When the clamp 3 can drive the workpiece to be welded to rotate, the welding equipment can perform multi-faceted welding on it, avoiding the situation where the clamp 3 cannot drive the workpiece to be welded to rotate and can only perform welding in a single position, resulting in the need to adjust the welding angle multiple times, simplifying the adjustment operation and improving the welding efficiency.

[0049] The two connecting cylinders 21 are fixedly connected with the meshing bevel gear 1 20, and the two meshing bevel gears 1 20 are vertically meshed with the rotating bevel gear 10 at the corresponding position. The two threaded rods 7 are fixedly connected with the meshing bevel gear 2 29, and the two meshing bevel gears 2 29 are vertically meshed with the rotating bevel gear 10 at the corresponding position. When the rotating bevel gear 10 rotates, it will drive the meshing bevel gear 1 20 and the meshing bevel gear 2 29 to rotate synchronously, that is, the rotating fixture 3 and the cleaning tool body 1 are carried out synchronously. Since the rotating fixture 3 represents that the welding device is in working condition at this time, the flying sparks have just fallen on the tool body 1. The flying sparks are hot when they are just generated, and it is easier to clean at this time. When the sparks cool down, they will directly adhere to the tool body 1, and cleaning is relatively difficult. When the welding work and cleaning work are carried out at the same time, the convenience of the rubber cleaning brush 26 in cleaning the flying metal particles is improved.

[0050] A moving block 25 is provided at both ends of the placement plate 5. The two moving blocks 25 are fixedly connected with a U-shaped rubber cleaning brush 26. Two holes 8 are provided through the right surfaces of the two moving blocks 25, and the two moving blocks 25 are movably connected to the two long rods 6. Threaded holes 27 are provided through the right surfaces of the two moving blocks 25, and the two moving blocks 25 are threadedly connected to the threaded rods 7 at corresponding positions. When the moving block 25 drives the rubber cleaning brush 26 to move toward the position of the fixed frame 18, it will first touch the pushing plate 24. At this time, the pushing plate 24 squeezes the spring 23. The spring 23 can absorb part of the impact force brought by the movement of the moving block 25, thereby avoiding the moving block 25 directly hitting the meshing bevel gear 29 and causing damage to the meshing bevel gear 29, thereby improving the service life of the meshing bevel gear 29.

[0051] The ends of the two moving blocks 25 facing away from the placement plate 5 are movably connected to the push plates 24, and each push plate 24 is movably connected to the long rod 6 at the corresponding position;

[0052] Among them, each push plate 24 is fixedly connected to a spring 23 on one side facing away from the placement plate 5, and each spring 23 is movably connected to the long rod 6 at the corresponding position, and the spring 23 is fixedly connected to the fixed frame 18 at the corresponding position on one side facing away from the placement plate 5. The rotation of the rotating bevel gear 10 will drive the meshing bevel gear 29 to start rotating synchronously. At this time, the two meshing bevel gears 29 drive the two threaded rods 7 to rotate. At this time, the moving block 25 threadedly connected to the threaded rod 7 will drive the rubber cleaning brush 26 to move in the tooling body 1, sweeping away the spark particles that were originally attached to the tooling body 1 when splashing, avoiding the splashing sparks from adhering to the tooling body 1 and causing corrosion and damage to it, thereby improving the service life of the equipment.

[0053] Working principle:

[0054] The first step is to start the motor 13. The motor 13 drives the short rod 11 to rotate, and the short rod 11 drives the driving gear to rotate synchronously. At this time, the synchronous chain 9 drives the two driven gears 31 to rotate, and the two short rods 2 30 rotate synchronously with the rotation of the synchronous chain 9. The short rod 2 30 drives the rotating bevel gear 10 to rotate, and the rotating bevel gear 10 drives the meshing bevel gear 20 to rotate. At this time, the connecting tube 21 and the driving gear 2 19 both start to rotate, and the synchronous chain 2 17 drives the driven gear 2 15 and the connecting rod 16 to rotate, and finally achieves the purpose of rotating the fixture 3. When the fixture 3 can drive the workpiece to be welded to rotate, the welding equipment can perform multi-faceted welding on it, avoiding the problem that the fixture 3 cannot drive the workpiece to be welded to rotate and can only perform welding in a single position, resulting in the need to adjust the welding angle multiple times, simplifying the adjustment operation and improving the welding efficiency.

[0055] In the second step, the rotation of the rotating bevel gear 10 will drive the meshing bevel gear 2 29 to start rotating synchronously. At this time, the two meshing bevel gears 29 drive the two threaded rods 7 to rotate. At this time, the moving block 25 threadedly sleeved on the threaded rod 7 will drive the rubber cleaning brush 26 to move in the tooling body 1, sweeping away the spark particles originally attached to the tooling body 1 during splashing, avoiding the splashing sparks from adhering to the tooling body 1 and causing corrosion and damage to it, thereby improving the service life of the equipment. When the rotating bevel gear 10 rotates, it will drive the meshing bevel gear 1 20 and the meshing bevel gear 2 29 to rotate synchronously, that is, the rotating fixture 3 and the cleaning tooling body 1 are carried out synchronously. Since the rotating fixture 3 represents that the welding device is in working condition at this time, the splashing sparks have just landed on the tooling body 1. The splashing sparks are hot when they are just generated, and it is easier to clean at this time. When the sparks cool down, they will directly adhere to the tooling body 1, and cleaning is relatively difficult. When the welding work and the cleaning work are carried out at the same time, the convenience of the rubber cleaning brush 26 in cleaning the splashing metal particles is improved.

[0056] When the two threaded rods 7 rotate and drive the moving block 25 to rotate, the two long rods 6 limit the moving block 25, so the moving block 25 and the rubber cleaning brush 26 do not rotate. At this time, the moving block 25 can only move along the direction of the long rod 6, and no position offset will occur, which improves the stability of the moving block 25 when driving the rubber cleaning brush 26 to clean. When the moving block 25 drives the rubber cleaning brush 26 to move toward the position of the fixed frame 18, it will first touch the pushing plate 24. At this time, the pushing plate 24 squeezes the spring 23, and the spring 23 can absorb part of the impact force brought by the movement of the moving block 25, thereby avoiding the moving block 25 directly hitting the meshing bevel gear 29 and causing damage to the meshing bevel gear 29, thereby improving the service life of the meshing bevel gear 29. The fixing ring 14 is directly connected to the tool body 1. At this time, when the motor 13 is started, the fixing ring 14 will provide a stable output environment for the started motor 13, thereby avoiding the continuous vibration of the motor 13 itself during output causing position offset, thereby improving the stability of the motor 13 when starting.
