Description

Technical Field

[0001] This utility model relates to the field of roller processing technology, and in particular to a welding device for roller processing. Background Technology

[0002] Rollers are cylindrical parts, divided into drive rollers and driven rollers. They are used in various transmission and conveying systems such as printing machines, digital printers, papermaking and packaging machinery, etc. They are mostly made of stainless steel, cast steel, or solid forged alloy steel core.

[0003] Welding is typically used in the processing of rollers. When manufacturing handheld extrusion rollers for automobile production, circular connectors need to be welded to both ends of the roller to ensure its proper rotation after pressing. This ensures a stable connection. Since the roller needs to rotate around its center during use, the center must be aligned before welding the roller and the circular connector. The rollers and circular connectors used in the production of handheld extrusion rollers are mostly small in size. Existing welding devices can only fix the position and cannot align the center of the roller and the circular connector. This requires manual alignment by workers, which reduces the welding efficiency of the roller. Therefore, this utility model provides a welding device for roller processing to meet the requirements. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a welding device for roller processing. After the fixed chuck is moved by the fixed frame, the center of the roller and the circular connecting frame can be directly connected and fitted. The above setting can solve the problem that the existing welding device cannot align the center of the roller and the circular connecting frame.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A welding device for roller processing includes a base plate with fixed frames at both ends. One fixed frame is fixedly connected to the base plate. Two movable grooves are formed at the top of the base plate. A movable block is slidably connected in the movable groove. The movable block extends out of the movable groove and is fixedly connected to the other fixed frame. A connecting shaft is rotatably connected in the fixed frame. A fixed chuck is fixedly connected to the fixed chuck through the fixed frame. A limit ring is fixedly connected to the inner wall of the fixed chuck. A transmission ring is rotatably connected to the outer wall of the limit ring. Three equidistant pawls are engaged at one end of the transmission ring. The pawls are slidably connected in the fixed chuck. A bevel gear is engaged at the other end of the transmission ring. A rotating disk is fixedly connected to the outside of the fixed chuck through the shaft of the bevel gear. A limit shaft is rotatably connected to one side of the other fixed frame. A screw is fixedly connected to one end of the limit shaft through the outside of the limit shaft. The screw is threadedly connected to one fixed frame.

[0007] Optionally, the limiting shaft is an I-shaped shaft, and a movable turntable is fixedly connected to one end of the screw.

[0008] Optionally, the fixed chuck is a hollow circular ring, and a baffle is fixedly connected to the middle of the fixed chuck. The baffle is an annular plate, and the transmission ring is rotatably connected between the fixed chuck and the baffle. The diameter of the inner wall of the fixed chuck is equal to the diameter of the inner wall of the baffle.

[0009] Optionally, the connecting shaft is T-shaped, the fixing frame has a cross-shaped hole in the middle, the connecting shaft has a cylindrical hole in the middle, one end of the connecting shaft passes through the cross-shaped hole of the fixing frame and is fixedly connected to the fixing chuck, and the diameter of the inner wall of the fixing chuck is equal to the diameter of the hole inside the connecting shaft.

[0010] Optionally, the lower end of the jaw is I-shaped, and the upper end of the fixed chuck has three I-shaped grooves corresponding to the jaw.

[0011] Optionally, the lower end of the chuck is provided with three arc-shaped grooves, the transmission ring includes a connecting plate, a spiral coil and a connecting tooth, the two sides of the connecting plate are fixedly connected to the spiral coil and the connecting tooth respectively, the spiral coil meshes with the arc-shaped groove at the lower end of the chuck, and the connecting tooth meshes with the bevel gear.

[0012] Optionally, a first gear is fixedly connected to the outer wall of each of the two connecting shafts. A second gear meshes with one side of the first gear. A drive shaft is fixedly connected to one end of the second gear that extends through the fixed frame. A connecting rod is fixedly connected to one end of the drive shaft. A connecting sleeve is slidably connected to one end of the connecting rod. The connecting sleeve is fixedly connected to the other end of the drive shaft. A motor is fixedly connected to one end of the base plate. The output end of the motor extends through the fixed frame and is fixedly sleeved with the second gear.

[0013] Optionally, the drive shaft and the screw are located at both ends of the fixed frame, and neither the drive shaft nor the screw is in contact with the chuck and the rotating disk.

[0014] Optionally, the connecting rod is a polygonal rod, and the inner cavity of the connecting sleeve is provided with a polygonal groove that matches the connecting rod.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] In the above solution, the transmission ring drives three jaws to simultaneously move towards the center of the fixed chuck for clamping, holding the roller or circular connecting frame to the center of the fixed chuck. The center of the roller, the circular connecting frame, and the fixed chuck are aligned on the same straight line. This allows the fixed frame to move the fixed chuck, directly aligning and fitting the centers of the roller and the circular connecting frame. Welding can then be performed using a welding device, increasing the docking speed of the roller and the circular connecting frame, thereby improving the welding efficiency of the roller. Furthermore, the solution can clamp rollers and circular connecting frames of multiple sizes, enhancing practicality.

[0017] After the motor starts, it drives the second gear to rotate, which in turn drives the connecting shaft to rotate through the first gear. This causes the fixed chuck to rotate. The rotation of the second gear also drives the transmission shaft to rotate. The two transmission shafts are movably connected by a connecting rod and a connecting sleeve, so the movement of the fixed frame does not affect the rotation of the transmission shaft. Therefore, the transmission shaft at one end drives the transmission shaft at the other end to rotate through the connecting rod and the connecting sleeve. This causes the two fixed chucks to rotate at the same speed, allowing the operator to perform ring welding on the roller from only one position, which facilitates the welding work.

[0030] like Figures 1 to 3 As shown, an embodiment of this utility model provides a welding device for roller processing, including a base plate 1. Fixed frames 2 are provided at both ends of the base plate 1. One fixed frame 2 is fixedly connected to the base plate 1. Two movable grooves 11 are formed at the top of the base plate 1. Movable blocks 12 are slidably connected within the movable grooves 11, and the movable blocks 12 extend out of the movable grooves 11 and are fixedly connected to the other fixed frame 2. A connecting shaft 3 is rotatably connected within the fixed frame 2, and a fixed chuck 4 is fixedly connected through the connecting shaft 3 and extending out of the fixed frame 2. A limiting ring 5 is fixedly connected to the inner wall of the fixed chuck 4, and a transmission ring 6 is rotatably connected to the outer wall of the limiting ring 5. One end of the transmission ring 6 is engaged with three equidistant annular jaws 7, which are slidably connected within the fixed chuck 4. The other end of the transmission ring 6 is engaged with a bevel gear 8, and the shaft of the bevel gear 8 extends through to the outside of the fixed chuck 4 and is fixedly connected to a rotating disk 9. A limiting shaft 13 is rotatably connected to one side of a fixed frame 2 that slides on the base plate 1. A screw 14 is fixedly connected to one end of the limiting shaft 13 that extends to the outside of the fixed frame 2. The screw 14 is threadedly connected to the fixed frame 2 that is fixed on the base plate 1. The limiting shaft 13 is an I-shaped shaft. A movable turntable is fixedly connected to one end of the screw 14. The fixed chuck 4 is a hollow ring. A baffle 10 is fixedly connected to the middle of the fixed chuck 4. The baffle 10 is an annular plate. A transmission ring 6 is rotatably connected between the fixed chuck 4 and the baffle 10. The diameter of the inner wall of the fixed chuck 4 is equal to the diameter of the inner wall of the baffle 10.

[0031] The connecting shaft 3 is T-shaped, and the middle part of the fixing frame 2 has a cross-shaped hole. The middle part of the connecting shaft 3 has a cylindrical hole. One end of the connecting shaft 3 passes through the cross-shaped hole of the fixing frame 2 and is fixedly connected to the fixing chuck 4. The diameter of the inner wall of the fixing chuck 4 is equal to the diameter of the hole inside the connecting shaft 3.

[0032] The lower end of the chuck 7 is I-shaped, the upper end of the fixed chuck 4 has three I-shaped grooves corresponding to the chuck 7, and the lower end of the chuck 7 has three arc-shaped grooves.

[0033] like Figure 3As shown, the transmission ring 6 includes a connecting plate 61, a spiral coil 62, and a connecting tooth 63. The two sides of the connecting plate 61 are fixedly connected to the spiral coil 62 and the connecting tooth 63, respectively. The spiral coil 62 meshes with the arc-shaped groove 71 at the lower end of the pawl 7, and the connecting tooth 63 meshes with the bevel gear 8.

[0034] In use, the base plate 1 restricts the movement direction of the other end moving block 12 through the moving groove 11 and the moving block 12. A connecting shaft 3 is rotatably connected inside the fixed frame 2. The connecting shaft 3 passes through the fixed frame 2 and is fixedly connected to a fixed chuck 4, so that the fixed frame 2 restricts the position of the fixed chuck 4 through the connecting shaft 3. A limit ring 5 is fixedly connected to the inner wall of the fixed chuck 4. A transmission ring 6 is rotatably connected to the outer wall of the limit ring 5, so that the fixed chuck 4 restricts the rotation position of the transmission ring 6 through the limit ring 5. Three equidistant ring-shaped jaws 7 are engaged at one end of the transmission ring 6. The jaws 7 are slidably connected inside the fixed chuck 4. A bevel gear 8 is engaged at the other end of the transmission ring 6. The rotating shaft of the bevel gear 8 passes through the outside of the fixed chuck 4 and is fixedly connected to a rotating disk 9, so that the operator can place the roller or... After the circular connecting frame is placed in the middle of the fixed chuck 4, the rotating disk 9 is rotated, causing the rotating disk 9 to drive the bevel gear 8 to rotate, which in turn drives the transmission ring 6 to rotate. The transmission ring 6 drives the three jaws 7 to move towards the center of the fixed chuck 4 simultaneously to clamp the roller or circular connecting frame to the center of the fixed chuck 4, so that the center of the roller, the circular connecting frame and the fixed chuck 4 are on the same straight line. After the fixed frame 2 moves the fixed chuck 4, the center of the roller and the circular connecting frame can be directly connected and fitted. Then, welding can be performed using a welding device, which improves the connection speed of the roller and the circular connecting frame, thereby improving the welding efficiency of the roller. It can also clamp rollers and circular connecting frames of multiple sizes, improving practicality.

[0035] One side of the other fixed frame 2 is rotatably connected to a limiting shaft 13. A screw 14 is fixedly connected to one end of the limiting shaft 13 that extends to the outside of the limiting shaft 13. The screw 14 is threadedly connected to one fixed frame 2, so that after the two fixed frames 2 clamp the roller and the circular connecting frame respectively, rotating the screw 14 can drive the other fixed frame 2 and the moving block 12 to move along the moving groove 11, ensuring that the centers of the two fixed frames 2 are always on the same straight line. Moreover, through the self-locking effect of the screw 14, the relative position of the two fixed frames 2 is stable during the welding process, resulting in a better welding effect.

[0036] The limiting shaft 13 is an I-shaped shaft, which can drive the fixed frame 2 at the other end to move. A movable turntable is fixedly connected to one end of the screw 14 to facilitate the rotation of the screw 14. The fixed chuck 4 is a hollow ring, and a baffle 10 is fixedly connected to the middle of the fixed chuck 4. The baffle 10 is an annular plate. The transmission ring 6 is rotatably connected between the fixed chuck 4 and the baffle 10. The diameter of the inner wall of the fixed chuck 4 is equal to the diameter of the inner wall of the baffle 10, so that the baffle 10 can restrict the rotation position of the transmission ring 6. The baffle 10 also closes the inner wall of the fixed chuck 4 without affecting the roller passing through the fixed chuck 4, and also prevents objects from falling on the transmission ring 6 and affecting the rotation of the transmission ring 6.

[0037] The connecting shaft 3 is T-shaped, and the fixing frame 2 has a cross-shaped hole in the middle, which restricts the rotation position of the connecting shaft 3. The connecting shaft 3 has a cylindrical hole in the middle, and one end of the connecting shaft 3 passes through the cross-shaped hole of the fixing frame 2 and is fixedly connected to the fixing chuck 4. The diameter of the inner wall of the fixing chuck 4 is equal to the diameter of the hole inside the connecting shaft 3, so that after the roller passes through the fixing chuck 4, it can pass through the fixing frame 2 through the connecting shaft 3, so that the length of the clamped roller is not limited, and the practicality of the device is improved.

[0038] The lower end of the jaw 7 is I-shaped, and the upper end of the fixed chuck 4 has three I-shaped grooves corresponding to the jaw 7, which makes the fixed chuck 4 effectively restrict the movement of the jaw 7. The lower end of the jaw 7 has three arc-shaped grooves. The transmission ring 6 includes a connecting plate, a spiral coil, and connecting teeth. The two sides of the connecting plate are fixedly connected to the spiral coil and the connecting teeth, respectively. The spiral coil meshes with the arc-shaped groove at the lower end of the jaw 7, and the connecting teeth mesh with the bevel gear 8. When the bevel gear 8 rotates, it drives the connecting plate to rotate through the connecting teeth, which in turn drives the spiral coil to rotate, causing the jaw 7 to move along the fixed chuck 4 to clamp or loosen the roller.

[0039] As one implementation method in this embodiment, such as Figure 1 and Figure 2 As shown, a first gear 15 is fixedly connected to the outer wall of both connecting shafts 3. A second gear 16 meshes with one side of the first gear 15. A transmission shaft 17 is fixedly connected to one end of the second gear 16 that passes through the fixed frame 2. A connecting rod 19 is fixedly connected to one end of the transmission shaft 17. A connecting sleeve 20 is slidably connected to one end of the connecting rod 19. The connecting sleeve 20 is fixedly connected to the other end of the transmission shaft 17. A motor 18 is fixedly connected to one end of the base plate 1. The output end of the motor 18 passes through the fixed frame 2 and is fixedly sleeved with the second gear 16.

[0040] The drive shaft 17 and screw 14 are located at both ends of the fixed frame 2. Neither the drive shaft 17 nor the screw 14 is in contact with the chuck 7 or the rotating disk 9. The connecting rod 19 is a polygonal rod, and the inner cavity of the connecting sleeve 20 has a polygonal groove that matches the connecting rod 19. After the motor 18 starts, it drives the second gear 16 to rotate, which in turn drives the connecting shaft 3 to rotate through the first gear 15, thereby causing the fixed chuck 4 to rotate. Since the rotation of the second gear 16 will drive the drive shaft 17 to rotate, and the two drive shafts 17 are movably connected through the connecting rod 19 and the connecting sleeve 20, the movement of the fixed frame 2 does not affect the rotation of the drive shaft 17. Therefore, the drive shaft 17 at one end drives the drive shaft 17 at the other end to rotate through the connecting rod 19 and the connecting sleeve 20, thereby causing the two fixed chucks 4 to rotate at the same speed. This allows the operator to perform ring welding on the roller from only one position, facilitating the welding work.

[0041] With the drive shaft 17 and screw 14 located at both ends of the fixed frame 2 respectively, neither the drive shaft 17 nor the screw 14 is in contact with the chuck 7 or the rotating disk 9, so that the drive shaft 17 and screw 14 will not interfere with the chuck 7 and the rotating disk 9. The connecting rod 19 is a polygonal rod, and the inner cavity of the connecting sleeve 20 is provided with a polygonal groove that matches the connecting rod 19, so that the connecting rod 19 and the connecting sleeve 20 will rotate simultaneously, thereby ensuring that the two fixed chucks 4 rotate at the same speed.

[0042] The working principle of the technical solution provided by this utility model is as follows:

[0043] In use, the base plate 1 is fixedly connected to one end of the fixed frame 2. The base plate 1 restricts the movement direction of the other end of the moving block 12 through the moving groove 11 and the moving block 12. The fixed frame 2 restricts the position of the fixed chuck 4 through the connecting shaft 3. The fixed chuck 4 restricts the rotation position of the transmission ring 6 through the limiting ring 5. After the operator places the roller or circular connecting frame into the middle of the fixed chuck 4, the rotating disk 9 is rotated, which drives the bevel gear 8 to rotate. In turn, the bevel gear 8 drives the transmission ring 6 to rotate, which in turn drives the three chuck jaws 7. Simultaneously, the roller or circular connecting frame is clamped towards the center of the fixed chuck 4, ensuring that the center of the roller, the circular connecting frame, and the fixed chuck 4 are on the same straight line. This allows the fixed frame 2 to move the fixed chuck 4, directly aligning and fitting the centers of the roller and the circular connecting frame. Welding can then be performed using a welding device, increasing the docking speed of the roller and the circular connecting frame, thereby improving the welding efficiency of the roller. Furthermore, it can clamp rollers and circular connecting frames of multiple sizes, enhancing practicality.

[0044] The position of the motor 18 is fixed by the fixing bracket 2, so that after the motor 18 starts, it drives the second gear 16 to rotate. The second gear 16 then drives the connecting shaft 3 to rotate through the first gear 15, thereby causing the fixed chuck 4 to rotate. Since the rotation of the second gear 16 will drive the transmission shaft 17 to rotate, and the two transmission shafts 17 are movably connected by the connecting rod 19 and the connecting sleeve 20, the movement of the fixing bracket 2 does not affect the rotation of the transmission shaft 17. Therefore, the transmission shaft 17 at one end drives the transmission shaft 17 at the other end to rotate through the connecting rod 19 and the connecting sleeve 20, so that the two fixed chucks 4 rotate at the same speed. This allows the operator to perform ring welding on the roller from only one position, which is convenient for the welding work.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0046] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
