Description

Technical Field

[0001] This invention relates to the field of welding machine technology, and more particularly to a friction welding machine. Background Technology

[0002] Friction welding, as a solid-state welding technology, has the advantages of high weld joint quality, energy saving and environmental protection, and high efficiency. It is widely used in machinery manufacturing, automotive industry and other fields. In order to balance costs, adapt to basic welding needs and reduce maintenance costs, most existing friction welding machines adopt the "motor + transmission belt" transmission scheme.

[0003] However, after long-term use, the transmission belt is prone to gradually loosening, which makes it impossible for the motor power to be stably transmitted to the spindle, resulting in slippage and free rotation. This causes uneven frictional heating on the workpiece contact surface, with varying amounts of heat, making it difficult to maintain a stable plastic state of the metal. Ultimately, this leads to defects such as incomplete penetration, uneven structure, and insufficient strength in the welded joint, seriously affecting the welding quality and reliability of the product.

[0004] Therefore, it is necessary to provide a friction welding machine to solve the above-mentioned technical problems. Summary of the Invention

[0005] The technical problem solved by this invention is to provide a friction welding machine that is easy to use, simple to operate, maintains stable rotation speed, and improves the friction welding effect.

[0006] To solve the above-mentioned technical problems, the present invention provides a friction welding machine, comprising: a vertical plate and a fixed plate fixedly installed on the outer wall of the main body, wherein the vertical plate and the fixed plate are both located between synchronous conveyor belts on the main body; crossbars are fixedly installed on the outer walls of both sides of the vertical plate; U-shaped plates are slidably installed on the two crossbars; push rollers are rotatably installed inside the two U-shaped plates; a plurality of compression springs are fixedly installed on the top of the fixed plate; a connecting plate is fixedly installed on the top of the plurality of compression springs; a mounting box is fixedly installed on the top of the connecting plate; a rotating rod is rotatably installed inside the mounting box, and both ends of the rotating rod extend outside the mounting box; a squeezing roller is fixedly sleeved on the rotating rod; and a lubrication mechanism, a sealing mechanism, and a stirring mechanism are provided inside the mounting box. The lubrication mechanism reduces the friction between the push roller and the squeezing roller, thereby reducing the wear of the push roller and the squeezing roller; the sealing mechanism reduces the evaporation of lubricating oil in the mounting box; and the stirring mechanism stirs the lubricating oil in the mounting box, making the overall viscosity of the lubricating oil uniform, the oil flow stable, and improving the lubrication effect.

[0007] Preferably, the lubrication mechanism includes lubricating oil disposed within the mounting housing.

[0008] The sealing mechanism includes fixed blocks that are fixedly installed on the inner walls of both sides of the mounting box. Sliding rods are slidably installed on the two fixed blocks respectively. Frame-shaped sealing plates are fixedly installed on the top ends of the two sliding rods. Force springs are movably sleeved on the two sliding rods respectively, and the top ends of the two force springs are fixedly connected to the frame-shaped sealing plates. The bottom ends of the two force springs are fixedly connected to the two fixed blocks respectively. Cams are fixedly installed at both ends of the rotating rod.

[0009] Preferably, the stirring mechanism includes a winding rod rotatably mounted on the inner wall of the bottom of the mounting box, with two pull ropes wound on the winding rod, and the two ends of the two pull ropes respectively fixedly connected to the bottom ends of the two sliding rods, and a stirring plate fixedly sleeved on the winding rod.

[0010] Preferably, the compression spring is a tin-plated spring.

[0011] Preferably, two stabilizing rods are fixedly installed on the top of the fixing plate, and both stabilizing rods pass through the connecting plate and are slidably connected to the connecting plate.

[0012] Preferably, the connecting plate has two through holes, and a linear bearing is fixedly installed in each of the two through holes. The two stabilizer rods pass through the two linear bearings and are slidably connected to the inner walls of the two linear bearings respectively.

[0014] Preferably, a rotating groove is provided on the bottom inner wall of the mounting box, the bottom end of the winding rod extends into the rotating groove and is fixedly fitted with a rotating bearing, and the outer wall of the rotating bearing is fixedly connected to the inner wall of the rotating groove.

[0015] Compared with related technologies, the friction welding machine provided by the present invention has the following beneficial effects:

[0016] This invention provides a friction welding machine that performs friction welding on products via its main body. When the synchronous conveyor belt becomes slack, a compression spring pushes two push rollers away from each other, causing the synchronous conveyor belt to expand outward and maintain a suitable tension. This allows the power from the motor on the main body to be stably transmitted to the main shaft, ultimately ensuring complete weld penetration and guaranteeing the quality of the final product. When the friction between the push roller and the extrusion roller is too high, the rotation of the push roller will cause the extrusion roller to rotate through friction, continuously applying lubricating oil from the mounting box to the push roller. The lubricating oil reduces the friction between the push roller and the extrusion roller, thereby reducing wear and increasing service life. Simultaneously, pulling the pull rope upward moves the stirring plate, causing it to rotate and stir the lubricating oil, resulting in uniform viscosity and stable flow of the lubricating oil, further improving the lubrication effect.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please refer to the following: Figures 1-7In an embodiment of the present invention, the friction welding machine includes: a vertical plate 3 and a fixed plate 7 fixedly installed on the outer wall of the main body 1, and both the vertical plate 3 and the fixed plate 7 are located between the synchronous conveyor belts 2 on the main body 1. Horizontal bars 4 are fixedly installed on the outer walls of both sides of the vertical plate 3, and U-shaped plates 5 are slidably installed on the two horizontal bars 4 respectively. Push rollers 6 are rotatably installed inside the two U-shaped plates 5 respectively. A plurality of compression springs 8 are fixedly installed on the top of the fixed plate 7. To prevent external dust from adhering to the compression springs 8, causing oxidation and rust on the surface of the compression springs 8 and affecting their service life, the compression springs 8 are tin-plated springs. In the initial state, the compression springs 8 are in a compressed state. When the synchronous conveyor belt 2 becomes slack, the compression springs... 8. The push mounting box 10 and the extrusion roller 12 move upward to contact the push roller 6, causing the two push rollers 6 to move away from each other and push the synchronous conveyor belt 2 outward, thereby keeping the synchronous conveyor belt 2 in a suitable tension state. A connecting plate 9 is fixedly installed on the top of several compression springs 8, and a mounting box 10 is fixedly installed on the top of the connecting plate 9. A rotating rod 11 is rotatably installed inside the mounting box 10, and both ends of the rotating rod 11 extend outside the mounting box 10. An extrusion roller 12 is fixedly sleeved on the rotating rod 11. A lubrication mechanism, a sealing mechanism, and a stirring mechanism are provided inside the mounting box 10. The lubrication mechanism includes lubricating oil provided in the mounting box 10. The lubrication mechanism reduces the friction between the push roller 6 and the extrusion roller 12, thereby lowering the push roller 6. 6. To reduce the wear of the extrusion roller 12, the sealing mechanism includes fixed blocks 14 fixedly installed on the inner walls of both sides of the mounting box 10. Sliding rods 17 are slidably installed on each of the two fixed blocks 14. Frame-shaped sealing plates 13 are fixedly installed at the top ends of the two sliding rods 17. Force springs 16 are movably sleeved on each of the two sliding rods 17, and the top ends of the two force springs 16 are fixedly connected to the frame-shaped sealing plates 13. The bottom ends of the two force springs 16 are fixedly connected to the two fixed blocks 14. Cams 15 are fixedly installed at both ends of the rotating rod 11. The sealing mechanism reduces the evaporation of lubricating oil inside the mounting box 10. The stirring mechanism includes a winding rod 19 rotatably installed on the inner wall of the bottom of the mounting box 10. To rotate the winding rod 19... Installed on the mounting box 10, the mounting box 10 has a rotating groove on its bottom inner wall. The bottom end of the winding rod 19 extends into the rotating groove and is fixedly fitted with a rotating bearing. The outer wall of the rotating bearing is fixedly connected to the inner wall of the rotating groove. Two pull ropes 21 are wound on the winding rod 19, and the two ends of the two pull ropes 21 are respectively fixedly connected to the bottom ends of two sliding rods 17. A stirring plate 20 is fixedly fitted on the winding rod 19. A torsion spring is movably fitted on the winding rod 19, and the top end of the torsion spring is fixedly connected to the stirring plate 20. The bottom end of the torsion spring is fixedly connected to the bottom inner wall of the mounting box 10. The stirring mechanism stirs the lubricating oil in the mounting box 10, so that the overall viscosity of the lubricating oil is uniform, the oil flow is stable, and the lubrication effect is improved.

[0027] To limit the movement of the connecting plate 9 and make its movement more stable, two stabilizing rods 18 are fixedly installed on the top of the fixing plate 7. Both stabilizing rods 18 pass through the connecting plate 9 and are slidably connected to it. To reduce the friction between the connecting plate 9 and the stabilizing rods 18, thereby reducing the wear between them and improving their service life, two through holes are provided on the connecting plate 9. Linear bearings are fixedly installed in the two through holes respectively. The two stabilizing rods 18 pass through the two linear bearings respectively and are slidably connected to the inner walls of the two linear bearings respectively.

[0028] In order to guide the pull rope 21 and convert the vertical tension on the pull rope 21 into a horizontal tension, thereby reducing the loss of tension and pulling the winding rod 19 to rotate, two guide rods are fixedly installed inside the mounting box 10, and the two guide rods are slidably connected to the two pull ropes 21 respectively.

[0029] The working principle of the friction welding machine provided by this invention is as follows: In the initial state, the mounting box 10 is filled with lubricating oil, the compression spring 8 is in a compressed state, the force spring 16 is in a stretched state, the frame-shaped sealing plate 13 is in close contact with the extrusion roller 12 and the mounting box 10, blocking the opening of the mounting box 10 and reducing the evaporation of lubricating oil. Friction welding is performed on the product through the body 1. When the synchronous conveyor belt 2 becomes loose after long-term use of the body 1, the compression spring 8 pushes the mounting box 10 and the extrusion roller 12 to move upward and contact the push roller 6, causing the two push rollers 6 to move away from each other and push the synchronous conveyor belt 2 outward, thereby keeping the synchronous conveyor belt 2 in a suitable tension state, so that the power of the motor on the body 1 is stably transmitted to the main shaft, and finally the weld joint is fully welded, ensuring the quality of the final product. At the same time, when the synchronous conveyor belt 2 moves, the friction force drives the push roller 6 to rotate. When the friction between the push roller 6 and the extrusion roller 12 is too high, the rotation of the push roller 6 will drive the extrusion roller 12 to rotate through friction. The rotation of the extrusion roller 12 will drive the rotating rod 11 to rotate, causing the cam 15 to rotate upward and push the frame-shaped sealing plate 13 to move upward and separate from the mounting box 10, no longer obstructing the extrusion roller 12. At the same time, the rotation of the extrusion roller 12 will continuously apply the lubricating oil in the mounting box 10 to the push roller 6. The lubricating oil will reduce the friction between the push roller 6 and the extrusion roller 12, thereby reducing the wear of the push roller 6 and the extrusion roller 12 and improving their service life. Meanwhile, the upward movement of the frame-shaped sealing plate 13 will drive the sliding rod 17 to move upward. The upward movement of the sliding rod 17 will pull the pull rope 21 to move upward. The movement of the pull rope 21 will drive the winding rod 19 to rotate, which will eventually cause the stirring plate 20 to rotate and stir the lubricating oil, thereby making the overall viscosity of the lubricating oil uniform and the oil flow stable, further improving the lubrication effect.

[0030] Compared with related technologies, the friction welding machine provided by the present invention has the following beneficial effects:

[0031] This invention provides a friction welding machine. The machine uses a main body 1 to perform friction welding on products. When the synchronous conveyor belt 2 becomes slack, a compression spring 8 pushes two push rollers 6 away from each other, causing the synchronous conveyor belt 2 to expand outwards and maintain a suitable tension. This allows the power from the motor on the main body 1 to be stably transmitted to the main shaft, ultimately ensuring complete weld penetration and guaranteeing the quality of the final product. When the friction between the push roller 6 and the extrusion roller 12 is too high, the rotation of the push roller 6 will cause the extrusion roller 12 to rotate, continuously applying lubricating oil from the mounting box 10 to the push roller 6. This lubricating oil reduces the friction between the push roller 6 and the extrusion roller 12, thereby reducing wear and increasing service life. Simultaneously, pulling the pull rope 21 upwards moves the stirring plate 20, causing it to rotate and stir the lubricating oil, resulting in uniform viscosity and stable flow, further improving the lubrication effect.
