Description

Technical Field

[0001] The invention relates to the technical field of bearing seat welding equipment, and in particular to a welding device used for bearing seat processing. Background Art

[0002] The main function of the bearing seat is to support the bearing and the transmission rod, so that they can run smoothly and withstand various loads generated during operation. In some mechanical designs, when the bearing seat needs to withstand greater loads or special working conditions, the supporting structure needs to be strengthened by welding.

[0003] Among them, when welding the supporting structure installed on the bearing seat, the welding slag generated by the welding tends to splash everywhere. The welding slag may splash into the bearing hole and may adhere to the bearing hole, causing the size of the bearing hole to change, affecting the accuracy of the bearing hole, and may affect the subsequent installation of the bearing. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a welding device for bearing seat processing, comprising a support table, a support frame is fixedly connected to the top of the support table, a welding machine is slidably connected to the bottom of the support frame, a fixing frame is fixedly connected to the top of the support table, an electric telescopic rod is fixedly connected to the side wall of the fixing frame, and a bearing seat is placed on the top of the support table;

[0005] A support mechanism, the support mechanism includes a sliding ring 1 slidably connected to the outer wall of the fixing frame, three arc-shaped support blocks are arranged on the outer wall of the fixing frame, the three arc-shaped support blocks are rotatably connected to two connecting rods 1 on one side close to the fixing frame, the inner walls of the three connecting rods 1 on the left side are rotatably connected to the outer wall of the fixing frame, the inner walls of the three connecting rods 1 on the right side are rotatably connected to the outer wall of the sliding ring 1, the three arc-shaped support blocks are fixedly connected to a fixing plate on one side close to the fixing frame, the inner walls of the three arc-shaped support blocks are slidably connected to rubber expansion blocks, the side walls of the six rubber expansion blocks are fixedly connected to five arc-shaped springs, thirty arc-shaped springs are arranged in groups of five, and the sides of the six groups of arc-shaped springs away from the six rubber expansion blocks are fixedly connected to the inner wall of the arc-shaped support blocks;

[0006] The expansion mechanism includes a fixed ring 1 fixedly connected to the outer wall of the fixed frame, a sliding ring 2 is slidably connected to the inner wall of the fixed ring 1, the side wall of the sliding ring 2 is fixedly connected to the side wall of the sliding ring 1, three inclined panels are fixedly connected to the side wall of the sliding ring 2, a blocking ring is fixedly connected to the inner wall of the fixed ring 1, three vents are opened on the side wall of the blocking ring, three hollow blocks are slidably connected to the inner wall of the fixed ring 1, three support blocks are fixedly connected to the inner wall of the fixed ring 1, three spring rotating plates are rotatably connected to the inner wall of the fixed ring 1, six gas hoses are connected through the outer wall of the fixed ring 1, and the outer walls of the six gas hoses are connected to six rubber expansion The inner wall of the block is connected through, the outer walls of the six gas hoses are slidably connected with the inner walls of the three arc-shaped support blocks, and a cooling component is arranged on the outer wall of the fixed ring 1. The staff places the bearing seat to be welded on the support table, sets the bearing hole of the bearing seat into the outer wall of the fixed frame, and then starts the electric telescopic rod to extend, pushing the sliding ring 1 to move toward the fixed ring 1. When the sliding ring 1 moves, the connecting rod 1 will rotate, thereby pushing the arc-shaped support block to expand outward. During the expansion process of the arc-shaped support block, the arc-shaped support blocks will be separated from each other, and the squeezing force on the rubber expansion block will disappear. Since the arc spring is in a compressed state, the squeezing force on the rubber expansion block is cancelled. After compression, the rebound force of the arc spring will be released, pushing the rubber expansion block out until the rubber expansion blocks contact each other, until the arc support block contacts the inner wall of the bearing hole of the bearing seat to support the bearing seat. At the same time, when the sliding ring 1 moves toward the fixed ring 1, it will also drive the sliding ring 2 and the inclined plate to move. The sliding ring 2 will squeeze the gas in the fixed ring 1. At this time, the compressed gas will be blocked by the blocking ring and the hollow block. Therefore, the gas will generate high pressure until the inclined plate contacts the hollow block. Since the contact surfaces of the two are inclined surfaces, and the outward expansion of the arc support block will drive the fixed plate to move, canceling the obstruction to the hollow block, so the inclined plate The hollow block will be lifted up smoothly. At the same time, the arc-shaped support block will also contact the inner wall of the bearing hole of the bearing seat. The rise of the hollow block will cause the vent of the plugging ring to leak out, allowing high-pressure gas to enter the plugging ring, and the gas will enter the gas hose. The gas is transported to the rubber expansion block through the gas hose to expand the rubber expansion block, thereby filling the bearing hole of the bearing seat and covering the bearing hole. After clamping the bearing seat, start the welding machine to weld the bearing seat. By clamping the bearing seat and fully covering the bearing hole at the same time, the welding slag generated by the welding is blocked, which can effectively prevent the welding slag from adhering to the bearing hole and affecting the size and shape of the bearing hole, thereby maintaining the accuracy and surface quality of the bearing hole.

[0007] Preferably, the cooling assembly includes three fixed frames fixedly connected to the outer wall of a fixed ring, the inner walls of the three fixed frames are slidably connected with sliding plates, the inner walls of the three sliding plates are slidably connected with four spring air-blocking plates, the inner walls of the three fixed frames are provided with two air inlet holes, the inner walls of the three sliding plates are fixedly connected to the outer walls of the three fixed plates, when the fixed plate rises, the sliding plate will be driven to rise, when the sliding plate covers the air inlet holes during the rising process, the sliding plate will squeeze the gas in the fixed frame, and the squeezed gas will be blocked by the spring air-blocking plates.

[0008] Preferably, the cooling assembly also includes four convex plates fixedly connected to the side of the sliding plate close to the arc-shaped support block, two air pipes are connected to the left and right sides of the three fixed frames, and the twelve air pipes are arranged in groups of four. The inner walls of the three arc-shaped support blocks are slidably connected to the outer walls of the three groups of air pipes, and a knocking assembly is provided on the outer wall of the fixed frame. Therefore, the gas will generate high pressure, and when the sliding plate rises, it will also drive the convex plate to move until the convex plate contacts the spring air blocking plate. The convex plate will push the spring air blocking plate to move, cancel the obstruction to the gas, and allow the gas to enter the air pipe. At the same time, as the arc-shaped support block moves, the air pipe is located inside the arc-shaped support block at this time, and the gas will be sprayed toward the inside of the arc-shaped support block through the air pipe to cool down the arc-shaped support block.

[0009] Preferably, the knocking assembly includes a fixing ring 2 fixedly connected to the outer wall of the fixing frame, three sliding frames are slidably connected to the outer wall of the fixing frame, three sliding plates are fixedly connected to a connecting frame on one side close to the fixing frame, three connecting frames are rotatably connected to a connecting rod 2 on one side close to the fixing frame, and the side walls of the three connecting frames are slidably connected to the inner walls of the three connecting rods 2.

[0010] Preferably, the knocking assembly also includes an inclined arc block slidably connected to the side of the arc support block close to the fixed frame, and the outer walls of the three inclined arc blocks are slidably connected to the inner walls of the three sliding frames. When the sliding plate rises, the connecting frame will rise, and the connecting rod 2 will rotate, thereby pulling the sliding frame to move in one direction of the fixed ring. When the arc support block expands outward, it will drive the inclined arc block to rise, allowing the inclined arc block to slide in the sliding frame. Therefore, when the sliding frame moves in one direction of the fixed ring, it will drive the inclined arc block to move.

[0011] Preferably, the knocking assembly also includes a transverse plate slidably connected to the inner wall of the arc-shaped support block, two spring blocks are fixedly connected to the side of the three transverse plates away from the fixed frame, and an extrusion ring is slidably connected to the inner wall of the second fixed ring, and the side walls of the extrusion ring are fixedly connected to the side walls of the three sliding frames until the inclined arc block contacts the transverse plate. Since the contact surfaces of the two are inclined surfaces, the inclined arc block will lift the transverse plate, thereby allowing the spring block to rise and leak out from the outer wall of the arc-shaped support block. Therefore, during the movement of the arc-shaped support block, the spring block will first contact the inner wall of the bearing hole, so that the spring block is squeezed and accumulates rebound force. When the arc-shaped support block contacts the inner wall of the bearing hole, the inclined arc block is recessed.

[0012] Preferably, the knocking assembly also includes three air inlet pipes connected through the inner wall of the fixed ring 2, the outer walls of the three air inlet pipes are slidably connected to the inner walls of the three sliding plates, and six racks are fixedly connected to the side walls of the extrusion ring. When the sliding frame moves toward the fixed ring 1, it will also drive the extrusion ring to move, allowing the extrusion ring to squeeze the gas in the fixed ring 2, and the squeezed gas enters the fixed frame to increase the gas in the fixed frame.

[0013] Preferably, the knocking assembly also includes a gear rod rotatably connected to the inner wall of the air pipe, and the outer walls of the twelve gear rods are fixedly connected with arc blocks. The twelve gear rods are grouped in pairs, and the outer walls of the six racks are meshed with the outer walls of the six groups of gear rods. At the same time, when the extrusion ring moves, it will also drive the rack to move, allowing the rack to mesh with the gear rod, thereby rotating the gear rod and the arc block. When gas is ejected from the air pipe, the arc block rotates, which will change the flow direction of the gas, thereby causing the airflow to be turbulent.

[0014] The present invention has the following beneficial effects:

[0015] (1) When the present invention is used, the staff places the bearing seat to be welded on the support platform, sets the bearing hole of the bearing seat into the outer wall of the fixed frame, and then starts the electric telescopic rod to extend, pushing the sliding ring 1 to move in the direction of the fixed ring 1. When the sliding ring 1 moves, the connecting rod 1 will rotate, thereby pushing the arc support block to expand outward. During the expansion of the arc support block, the arc support blocks will be separated from each other, and the squeezing force on the rubber expansion block will disappear. Since the arc spring is in a compressed state, after the squeezing of the rubber expansion block is cancelled, the rebound force of the arc spring will be released, pushing the rubber expansion block to extend until the rubber expansion blocks are in contact with each other, until the arc support block is in contact with the inner wall of the bearing hole of the bearing seat, so as to support the bearing seat. At the same time, when the sliding ring 1 moves in the direction of the fixed ring 1, it will also drive the sliding ring 2 and the inclined plate to move. The sliding ring 2 will squeeze the gas in the fixed ring 1. At this time, the compressed The gas that shrinks will be blocked by the blocking ring and the hollow block, so the gas will generate high pressure until the inclined plate contacts the hollow block. Since the contact surfaces of the two are inclined surfaces, and the outward expansion of the arc-shaped support block will drive the fixed plate to move, canceling the obstruction to the hollow block, the inclined plate will smoothly lift the hollow block. At the same time, the arc-shaped support block will also contact the inner wall of the bearing hole of the bearing seat. The rise of the hollow block will cause the vent of the blocking ring to leak out, allowing the high-pressure gas to enter the blocking ring, and the gas will enter the gas transmission hose, and the gas will be transported to the rubber expansion block through the gas transmission hose to expand the rubber expansion block, thereby filling the bearing hole of the bearing seat and covering the bearing hole. After clamping the bearing seat, start the welding machine to weld the bearing seat. By clamping the bearing seat and fully covering the bearing hole at the same time, the welding slag generated by the welding is blocked, which effectively prevents the welding slag from adhering to the bearing hole and affecting the size and shape of the bearing hole, thereby maintaining the accuracy and surface quality of the bearing hole.

[0016] (2) When the fixed plate of the present invention rises, it will drive the sliding plate to rise. When the sliding plate rises and covers the air inlet, the sliding plate will squeeze the gas in the fixed frame. At this time, the squeezed gas will be blocked by the spring air blocking plate, so the gas will generate high pressure. When the sliding plate rises, it will also drive the convex plate to move until the convex plate contacts the spring air blocking plate. The convex plate will push the spring air blocking plate to move, eliminating the obstruction to the gas and allowing the gas to enter the gas pipe. At the same time, as the arc-shaped support block moves, the gas pipe is now located inside the arc-shaped support block, and the gas It will be sprayed toward the inside of the arc support block through the air pipe to cool down the arc support block, effectively preventing the heat from the bearing seat welding from being transferred to the arc support block, causing the temperature of the arc support block to rise. When the next bearing seat is clamped, the temperature has not yet fully dissipated, allowing the arc support block to accumulate temperature, which may cause the arc support block to expand slightly, increase the clamping force, and cause slight deformation in some areas of the bearing hole. By cooling, the heat dissipation speed of the arc support block is accelerated, the expansion of the arc support block is avoided, and the deformation of the bearing hole is effectively prevented.

[0017] (3) When the sliding plate rises, the connecting frame rises, and the second connecting rod rotates, thereby pulling the sliding frame to move toward one direction of the fixed ring. When the arc-shaped support block expands outward, it drives the inclined arc block to rise, allowing the inclined arc block to slide in the sliding frame. Therefore, when the sliding frame moves toward one direction of the fixed ring, it drives the inclined arc block to move until the inclined arc block contacts the transverse plate. Since the contact surfaces of the two are inclined surfaces, the inclined arc block will lift the transverse plate, thereby causing the spring block to rise and leak out from the outer wall of the arc-shaped support block. Therefore, the arc-shaped support block During the movement, the spring block will first contact the inner wall of the bearing hole, so that the spring block will be squeezed and accumulate rebound force. When the arc support block contacts the inner wall of the bearing hole, the recessed position of the inclined arc block will contact the transverse plate. At this time, the rebound force of the spring block will be released, allowing the transverse plate to return to its position. At the same time, the spring block will shake slightly and lightly knock on the inner wall of the bearing hole of the bearing seat, which can help distribute stress and reduce stress concentration during the clamping process of the arc support block, so that the stress distribution in the bearing hole of the bearing seat is uniform, avoiding local overload and affecting the shape of the bearing hole.

[0018] (4) When the sliding frame moves toward the first direction of the fixed ring, the present invention also drives the extrusion ring to move, allowing the extrusion ring to squeeze the gas in the second fixed ring. The squeezed gas enters the fixed frame, thereby increasing the gas in the fixed frame. At the same time, when the extrusion ring moves, it also drives the rack to move, allowing the rack to mesh with the gear rod, thereby allowing the gear rod to rotate and the arc surface block to rotate. When gas is ejected from the gas pipe, the arc surface block rotates, which changes the flow direction of the gas, thereby causing the airflow to be turbulent. By increasing the gas in the fixed frame and causing the airflow to be turbulent, the contact area between the fluid and the surface of the arc support block is increased, which can accelerate the dispersion of heat and thus accelerate the heat exchange process.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] For example, see Figure 1-Figure 6 The present invention is a welding device for bearing seat processing, comprising a support platform 1, a support frame 11 is fixedly connected to the top of the support platform 1, a welding machine 12 is slidably connected to the bottom of the support frame 11, a fixing frame 13 is fixedly connected to the top of the support platform 1, an electric telescopic rod 14 is fixedly connected to the side wall of the fixing frame 13, and a bearing seat 15 is placed on the top of the support platform 1;

[0035] The support mechanism 2 comprises a sliding ring 21 slidably connected to the outer wall of the fixing frame 13, three arc-shaped support blocks 23 are arranged on the outer wall of the fixing frame 13, the three arc-shaped support blocks 23 are rotatably connected to two connecting rods 22 on one side close to the fixing frame 13, the inner walls of the three connecting rods 22 on the left side are rotatably connected to the outer wall of the fixing frame 13, the inner walls of the three connecting rods 22 on the right side are rotatably connected to the outer wall of the sliding ring 21, the three arc-shaped support blocks 23 are fixedly connected to a fixing plate 231 on one side close to the fixing frame 13, the inner walls of the three arc-shaped support blocks 23 are slidably connected to rubber expansion blocks 24, the side walls of the six rubber expansion blocks 24 are fixedly connected to five arc-shaped springs 241, thirty arc-shaped springs 241 are arranged in groups of five, and the sides of the six groups of arc-shaped springs 241 away from the six rubber expansion blocks 24 are fixedly connected to the inner wall of the arc-shaped support blocks 23;

[0036] The expansion mechanism 3 includes a fixed ring 131 fixedly connected to the outer wall of the fixed frame 13, a sliding ring 2 32 is slidably connected to the inner wall of the fixed ring 13, the side wall of the sliding ring 2 32 is fixedly connected to the side wall of the sliding ring 1 21, three inclined panels 33 are fixedly connected to the side wall of the sliding ring 2 32, a blocking ring 34 is fixedly connected to the inner wall of the fixed ring 1 31, three vents 341 are provided on the side wall of the blocking ring 34, three hollow blocks 35 are slidably connected to the inner wall of the fixed ring 1 31, three support blocks 36 are fixedly connected to the inner wall of the fixed ring 1 31, three spring rotating plates 37 are rotatably connected to the inner wall of the fixed ring 1 31, and six gas hoses 38 are connected through the outer wall of the fixed ring 1 31. The outer walls of 38 are all connected with the inner walls of the six rubber expansion blocks 24, and the outer walls of the six gas hoses 38 are all slidably connected with the inner walls of the three arc-shaped support blocks 23. A cooling component 4 is arranged on the outer wall of the fixed ring 13. The staff places the bearing seat 15 to be welded on the support platform 1, sets the bearing hole of the bearing seat 15 into the outer wall of the fixed frame 13, and then starts the electric telescopic rod 14 to extend, pushing the sliding ring 121 to move toward the fixed ring 13. When the sliding ring 121 moves, the connecting rod 122 will rotate, thereby pushing the arc-shaped support block 23 to expand outward. During the expansion process of the arc-shaped support block 23, the arc-shaped support block 23 will be separated from each other, and the squeezing force on the rubber expansion block 24 disappears. The arc spring 241 is in a compressed state. After the extrusion of the rubber expansion block 24 is cancelled, the resilience of the arc spring 241 will be released, pushing the rubber expansion block 24 out until the rubber expansion block 24 contacts each other, until the arc support block 23 contacts the inner wall of the bearing hole of the bearing seat 15, and supports the bearing seat 15. At the same time, when the sliding ring 1 21 moves toward the fixed ring 1 31, it will also drive the sliding ring 2 32 and the inclined plate 33 to move. The sliding ring 2 32 will squeeze the gas in the fixed ring 1 31. At this time, the compressed gas will be blocked by the blocking ring 34 and the hollow block 35. Therefore, the gas will generate high pressure until the inclined plate 33 contacts the hollow block 35. Since the contact surfaces of the two are inclined surfaces and the arc support The outward expansion of the support block 23 will drive the fixed plate 231 to move, eliminating the obstruction to the hollow block 35. Therefore, the inclined plate 33 will smoothly lift the hollow block 35. At the same time, the arc-shaped support block 23 will also contact the inner wall of the bearing hole of the bearing seat 15. The rise of the hollow block 35 will cause the vent 341 of the blocking ring 34 to leak out, allowing high-pressure gas to enter the blocking ring 34. The gas will then enter the gas hose 38, and the gas will be transported to the rubber expansion block 24 through the gas hose 38, allowing the rubber expansion block 24 to expand, thereby filling the bearing hole of the bearing seat 15 and covering the bearing hole. After the bearing seat 15 is clamped, the welding machine 12 is started to weld the bearing seat 15. By clamping the bearing seat 15 and fully covering the bearing hole at the same time, the welding slag generated by the welding is blocked.Effectively prevent welding slag from adhering to the bearing hole and affecting the size and shape of the bearing hole, thereby maintaining the accuracy and surface quality of the bearing hole.

[0037] For example 2, please refer to Figure 7-Figure 11 The present invention is a welding device for bearing seat processing. On the basis of Example 1, the cooling component 4 includes three fixed frames 41 fixedly connected to the outer wall of the fixed ring 31, the inner walls of the three fixed frames 41 are slidably connected with sliding plates 42, the inner walls of the three sliding plates 42 are slidably connected with four spring air blocking plates 43, the inner walls of the three fixed frames 41 are provided with two air inlet holes 411, the inner walls of the three sliding plates 42 are fixedly connected to the outer walls of the three fixed plates 231, when the fixed plate 231 rises, the sliding plate 42 will be driven to rise, when the sliding plate 42 covers the air inlet hole 411 during the rising process, the sliding plate 42 will squeeze the gas in the fixed frame 41, and the squeezed gas will be blocked by the spring air blocking plate 43.

[0038] The cooling assembly 4 also includes four convex plates 44 fixedly connected to the side of the sliding plate 42 close to the arc-shaped support block 23. The left and right sides of the three fixed frames 41 are connected through two gas pipes 45. The twelve gas pipes 45 are grouped in fours. The inner walls of the three arc-shaped support blocks 23 are slidably connected to the outer walls of the three groups of gas pipes 45. A knocking assembly 5 is provided on the outer wall of the fixed frame 13. Therefore, the gas will generate high pressure. When the sliding plate 42 rises, it will also drive the convex plate 44 to move until the convex plate 44 contacts the spring air blocking plate 43. The convex plate 44 will push the spring air blocking plate 43 to move, cancel the obstruction to the gas, and allow the gas to enter the gas pipe 45. At the same time, with the movement of the arc-shaped support block 23, the gas pipe 45 is located inside the arc-shaped support block 23 at this time, and the gas will be ejected toward the inside of the arc-shaped support block 23 through the gas pipe 45 to cool the arc-shaped support block 23.

[0039] The knocking assembly 5 includes a fixing ring 2 51 fixedly connected to the outer wall of the fixing frame 13, three sliding frames 52 are slidably connected to the outer wall of the fixing frame 13, the three sliding plates 42 are fixedly connected to the side of the fixing frame 13 close to the fixing frame 13 with a connecting frame 53, the three connecting frames 53 are rotatably connected to the side of the fixing frame 13 with a connecting rod 2 531, and the side walls of the three connecting frames 53 are slidably connected to the inner walls of the three connecting rods 2 531.

[0040] The knocking assembly 5 also includes an inclined arc block 54 slidably connected to the side of the arc support block 23 close to the fixed frame 13. The outer walls of the three inclined arc blocks 54 are slidably connected to the inner walls of the three sliding frames 52. When the sliding plate 42 rises, the connecting frame 53 will rise, and the connecting rod 2 531 will rotate, thereby pulling the sliding frame 52 to move toward the fixed ring 31. When the arc support block 23 expands outward, it will drive the inclined arc block 54 to rise, allowing the inclined arc block 54 to slide in the sliding frame 52. Therefore, when the sliding frame 52 moves toward the fixed ring 31, it will drive the inclined arc block 54 to move.

[0041] The knocking assembly 5 also includes a transverse plate 55 slidably connected to the inner wall of the arc-shaped support block 23. Two spring blocks 551 are fixedly connected to the side of the three transverse plates 55 away from the fixed frame 41. An extrusion ring 56 is slidably connected to the inner wall of the fixed ring 251. The side walls of the extrusion ring 56 are fixedly connected to the side walls of the three sliding frames 52 until the inclined arc block 54 contacts the transverse plate 55. Since the contact surfaces of the two are inclined surfaces, the inclined arc block 54 will lift the transverse plate 55, thereby allowing the spring block 551 to rise and leak out from the outer wall of the arc-shaped support block 23. Therefore, during the movement of the arc-shaped support block 23, the spring block 551 will first contact the inner wall of the bearing hole, so that the spring block 551 is squeezed and accumulates rebound force. When the arc-shaped support block 23 contacts the inner wall of the bearing hole, the inclined arc block 54 is recessed.

[0042] The knocking assembly 5 also includes three air inlet pipes 57 which are connected to the inner wall of the fixed ring 2 51. The outer walls of the three air inlet pipes 57 are slidably connected to the inner walls of the three sliding plates 42. Six racks 58 are fixedly connected to the side walls of the extrusion ring 56. When the sliding frame 52 moves toward the fixed ring 1 31, it will also drive the extrusion ring 56 to move, allowing the extrusion ring 56 to squeeze the gas in the fixed ring 2 51. The squeezed gas enters the fixed frame 41 through 47, increasing the gas in the fixed frame 41.

[0043] The striking assembly 5 also includes a gear rod 581 rotatably connected to the inner wall of the gas pipe 45. The outer walls of the twelve gear rods 581 are fixedly connected with arc blocks 582. The twelve gear rods 581 are grouped in pairs. The outer walls of the six racks 58 are meshed and connected with the outer walls of the six groups of gear rods 581. At the same time, when the extrusion ring 56 moves, it will also drive the rack 58 to move, so that the rack 58 and the gear rod 581 are meshed, so that the gear rod 581 rotates, and the arc block 582 rotates. When gas is ejected from the gas pipe 45, the arc block 582 rotates, which will change the flow direction of the gas, thereby causing the airflow to be turbulent.

[0044] There is no limitation on the number of the above components, and relevant technicians in the field can freely set them according to actual needs, as long as the above components are installed at the connection positions of the corresponding components.

[0045] A specific application of this embodiment is: when the present invention is used, the staff places the bearing seat 15 to be welded on the support platform 1, sets the bearing hole of the bearing seat 15 into the outer wall of the fixing frame 13, and then starts the electric telescopic rod 14 to extend, pushing the sliding ring 21 to move toward the fixing ring 31. When the sliding ring 21 moves, the connecting rod 22 rotates, thereby pushing the arc support block 23 to expand outward. During the expansion process of the arc support block 23, the arc support blocks 23 are separated from each other, which is conducive to the rubber expansion block 24. The squeezing force disappears. Since the arc spring 241 is in a compressed state, after the squeezing of the rubber expansion block 24 is cancelled, the resilience of the arc spring 241 will be released, pushing the rubber expansion block 24 out until the rubber expansion blocks 24 contact each other, until the arc support block 23 contacts the inner wall of the bearing hole of the bearing seat 15, supporting the bearing seat 15. At the same time, when the sliding ring 1 21 moves toward the fixing ring 1 31, it will also drive the sliding ring 2 32 and the inclined plate 33 to move, and the sliding ring 2 32 will squeeze the fixing ring 1 31. At this time, the compressed gas will be blocked by the blocking ring 34 and the hollow block 35, so the gas will generate high pressure until the inclined plate 33 contacts the hollow block 35. Since the contact surfaces of the two are inclined surfaces, and the arc-shaped support block 23 expands outward to drive the fixed plate 231 to move, canceling the obstruction of the hollow block 35, the inclined plate 33 will smoothly lift the hollow block 35. At the same time, the arc-shaped support block 23 will also contact the inner wall of the bearing hole of the bearing seat 15. The rise of the hollow block 35 will cause the vent 341 of the blocking ring 34 to leak out, allowing the high-pressure gas After entering the blocking ring 34, the gas will enter the gas hose 38, and the gas will be transported to the rubber expansion block 24 through the gas hose 38, so that the rubber expansion block 24 will expand, thereby filling the bearing hole of the bearing seat 15 and covering the bearing hole. After the bearing seat 15 is clamped, the welding machine 12 is started to weld the bearing seat 15. By clamping the bearing seat 15 and fully covering the bearing hole at the same time, the welding slag generated by the welding is blocked, and the welding slag is effectively prevented from adhering to the bearing hole and affecting the size and shape of the bearing hole, thereby maintaining the accuracy and surface quality of the bearing hole;

[0046] Among them, when the hollow block 35 rises, the obstruction to the spring rotating plate 37 will disappear. Since the spring rotating plate 37 is in a compressed state, after the obstruction is removed, the resilience of the spring rotating plate 37 will be released, allowing the spring rotating plate 37 to rotate toward the bottom of the hollow block 35, so that the side of the spring rotating plate 37 close to the fixing frame 13 is parallel to the bottom of the hollow block 35, and the bottom of the hollow block 35 is supported. When the welding of the bearing seat 15 is completed, the electric telescopic rod 14 is retracted to allow the sliding ring 1 21 and the sliding ring 2 32 to return to their positions, and at the same time, the arc support block 23 and the fixing plate 231 are returned to their positions. When the arc support block 23 returns to its position, the rubber expansion blocks 24 will contact each other, so that the rubber expansion blocks 24 are squeezed against each other, so that the rubber expansion blocks 24 are retracted into the arc When the sliding ring 23 returns to its original position, the inclined plate 33 will separate from the hollow block 35. At this time, the hollow block 35 is supported by the spring rotating plate 37. Therefore, the vent hole 341 is also connected to the fixed ring 1 31, so that the gas of the rubber expansion block 24 will enter the fixed ring 1 31 again, preventing the rubber expansion block 24 from expanding and affecting the rubber expansion block 24 from retracting into the arc-shaped support block 23. As the arc-shaped support block 23 returns to its original position, the fixed plate 231 will contact the hollow block 35, thereby squeezing the hollow block 35 downward, squeezing the spring rotating plate 37, and rotating the spring rotating plate 37 to accumulate resilience. When the hollow block 35 descends, it will block the vent hole 341 again, so that the fixed ring 1 31 is in a sealed state again.

[0047] Secondly, when the fixed plate 231 rises, the sliding plate 42 is driven to rise. When the sliding plate 42 rises and covers the air inlet 411, the sliding plate 42 squeezes the gas in the fixed frame 41. At this time, the squeezed gas is blocked by the spring air blocking plate 43, so the gas will generate high pressure. When the sliding plate 42 rises, it will also drive the convex plate 44 to move until the convex plate 44 contacts the spring air blocking plate 43. The convex plate 44 will push the spring air blocking plate 43 to move, cancel the obstruction to the gas, and let the gas enter the gas pipe 45. At the same time, with the movement of the arc support block 23, the gas pipe 45 is now located at the arc support block 23. Inside, the gas will be ejected toward the inside of the arc support block 23 through the gas pipe 45, cooling the arc support block 23, effectively preventing the heat of the welding of the bearing seat 15 from being transferred to the arc support block 23, causing the temperature of the arc support block 23 to rise. When the next bearing seat 15 is clamped, the temperature has not been fully dissipated, allowing the arc support block 23 to accumulate temperature, which may cause the arc support block 23 to expand slightly, increase the clamping force, and cause slight deformation in some areas of the bearing hole. By cooling, the heat dissipation speed of the arc support block 23 is accelerated, the expansion of the arc support block 23 is avoided, and the deformation of the bearing hole is effectively prevented;

[0048] Secondly, when the sliding plate 42 rises, the connecting frame 53 will rise, and the connecting rod 2 531 will rotate, thereby pulling the sliding frame 52 to move toward the fixing ring 31. When the arc support block 23 expands outward, the inclined arc block 54 will be driven to rise, allowing the inclined arc block 54 to slide in the sliding frame 52. Therefore, when the sliding frame 52 moves toward the fixing ring 31, the inclined arc block 54 will be driven to move until the inclined arc block 54 contacts the transverse plate 55. Since the contact surfaces of the two are inclined surfaces, the inclined arc block 54 will lift the transverse plate 55, thereby allowing the spring block 551 to rise and leak out from the outer wall of the arc support block 23. During the movement of the arc-shaped support block 23, the spring block 551 will first contact the inner wall of the bearing hole, so that the spring block 551 is squeezed and accumulates resilience. When the arc-shaped support block 23 contacts the inner wall of the bearing hole, the recessed position of the inclined arc-shaped block 54 will contact the transverse plate 55. At this time, the resilience of the spring block 551 will be released, allowing the transverse plate 55 to return to its original position. At the same time, the spring block 551 will shake slightly and slightly knock on the inner wall of the bearing hole of the bearing seat 15, which can help distribute the stress and reduce the stress concentration during the clamping process of the arc-shaped support block 23, so that the stress distribution in the bearing hole of the bearing seat 15 is uniform, avoiding local overload and affecting the shape of the bearing hole.

[0049] Secondly, when the sliding frame 52 moves toward the fixed ring 1 31, it will also drive the extrusion ring 56 to move, so that the extrusion ring 56 squeezes the gas in the fixed ring 2 51, and the squeezed gas enters the fixed frame 41 through 47, increasing the gas in the fixed frame 41. At the same time, when the extrusion ring 56 moves, it will also drive the rack 58 to move, so that the rack 58 is meshed with the gear rod 581, so that the gear rod 581 rotates, and the arc block 582 rotates. When the gas is ejected from the gas delivery pipe 45, the arc block 582 rotates, which will change the flow direction of the gas, thereby making the airflow turbulent. By increasing the gas in the fixed frame 41 and making the airflow turbulent to increase the contact area between the fluid and the surface of the arc support block 23, the heat dispersion can be accelerated, thereby accelerating the heat exchange process.

[0050] When the arc-shaped support block 23 retracts, the sliding plate 42 will also return to its original position. At this time, the air inlet 411 will be connected to the top of the sliding plate 42 again, and the external air will enter the fixed frame 41 through the sliding plate 42 to complete the gas replenishment.
