Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a concentricity positioning device for welding axle sleeves of a truck, comprising a processing table 1, a mounting frame 2 is fixedly connected to the upper part of the processing table 1, a support plate 3 is fixedly connected to the rear side of the upper part of the processing table 1, a rotating rod 7 is rotatably connected to the middle part of the mounting frame 2, a spur gear 8 is fixedly connected to the outside of the rotating rod 7, a first rack plate 9 is meshedly connected to the lower side of the outer part of the spur gear 8, a second rack plate 10 is meshedly connected to the upper part of the spur gear 8, the first rack plate 9 and the second rack plate 10 are both fixedly connected to the outside with a guide ring 11, the first rack plate 9 and the second rack plate 10 are both fixedly connected to the upper part with a mounting block 12, the upper parts of the two mounting blocks 12 are both fixedly connected to a moving plate 13, the lower parts of the two moving plates 13 are both fixedly connected to a slider 15, the upper parts of the two moving plates 13 are both fixedly connected to a fixing frame 14, and the two fixing The fixed frame 14 is fixedly connected to the outside with a transverse plate 17, and the two transverse plates 17 are provided with a flip assembly 21 on the outside. The flip assembly 21 is used to flip the half-axle sleeve. The left fixed frame 14 is installed with an electric push rod 18 on the outside, and the output end of the electric push rod 18 is fixedly connected to the outside of the right fixed frame 14. Guide rods 23 are fixedly connected to both sides of the inside of the mounting frame 2, and two guide rings 11 are slidably connected to the inside of the two guide rods 23. A telescopic rod 19 is installed on the outside of the right fixed frame 14, and the top of the telescopic rod 19 is fixedly connected to the outside of the left fixed frame 14. Slide grooves 16 are provided on both sides of the upper part of the mounting frame 2, and two sliders 15 are slidably connected to the inside of the two slide grooves 16. The first cylinder 4 is fixedly connected to the inside of the support plate 3, and the output end of the first cylinder 4 is fixedly connected to the mounting plate 5, and a welding gun 6 is installed on the outside of the mounting plate 5.
[0027] When aligning the half-axle sleeve, first, place the half-axle sleeve in the middle of the two clamping plates 2108, then start the second cylinder 2107, and the two second cylinders 2107 move the clamping plates 2108 fixed at the output end relative to each other, and the half-axle sleeve can be fixed by the relative movement of the two clamping plates 2108. This process does not require manual intervention, and automatic operation is realized. Next, start the electric push rod 18, and the electric push rod 18 contracts to drive the left fixed frame 14 to move. When the left fixed frame 14 moves, it drives the lower fixed moving plate 13 to move together. When the moving plate 13 moves, the mounting block 12 connected to its lower part also moves. When the mounting block 12 moves, the lower fixed first rack plate 9 also moves. When the first rack plate 9 moves, the meshing spur gear 8 starts to rotate.

This automatic alignment ensures the best concentricity accuracy.
[0028] Reference Figure 2 , Figure 3 and Figure 4 The flip assembly 21 includes a motor 2101, which is arranged outside the two horizontal plates 17. The output end of the motor 2101 is fixedly connected to a first bevel gear 2102, and the first bevel gear 2102 is externally meshed and connected to a second bevel gear 2103. The second bevel gear 2103 is internally fixedly connected to a transmission rod 2104, and the transmission rod 2104 is rotatably connected to the inside of the horizontal plate 17. The transmission rod 2104 is externally fixedly connected to a rotating disk 2105, and the rotating disk 2105 is externally fixed. A limit rod 2109 is connected, fixed blocks 2106 are fixedly connected on both sides of the outside of the rotating disk 2105, the second cylinders 2107 are fixedly connected inside the two fixed blocks 2106, the clamping plates 2108 are fixedly connected to the output ends of the two second cylinders 2107, the mounting ring 20 is fixedly connected to the outside of the cross plate 17, the motor 2101 is fixedly connected to the inside of the mounting ring 20, an annular groove 22 is opened on the outside of the cross plate 17, and the limit rod 2109 is slidably connected to the inside of the annular groove 22.
[0029] When welding the half-axle sleeve, by starting the motor 2101, the motor 2101 drives the first bevel gear 2102 fixed at the output end to rotate. When the first bevel gear 2102 rotates, it drives the second bevel gear 2103 meshing with the outside to rotate synchronously. When the second bevel gear 2103 rotates, it drives the transmission rod 2104 fixed inside to rotate together. During the rotation of the transmission rod 2104, the rotating disk 2105 fixed outside is driven to rotate. The rotation of the rotating disk 2105 further drives the half-axle sleeve fixed outside to flip, so that when welding the half-axle sleeve, the half-axle sleeve can be automatically flipped without the operator manually flipping it. Compared with manual flipping, the operation time is greatly shortened, and the welding quality of the half-axle sleeve is improved. The limit rod 2109 is slidably connected to the inside of the annular groove 22, which plays a limiting role.
[0030] Working principle: When aligning the half-axle sleeve, first, place the half-axle sleeve in the middle of the two clamping plates 2108, then start the second cylinder 2107, the two second cylinders 2107 move the clamping plates 2108 fixed at the output end relative to each other, the half-axle sleeve can be fixed by the relative movement of the two clamping plates 2108, then start the electric push rod 18, the electric push rod 18 shrinks and moves the left fixed frame 14, the movement of the left fixed frame 14 moves the lower fixed moving plate 13, the movement of the moving plate 13 moves the lower The fixed mounting block 12 moves, and the mounting block 12 moves with the first rack plate 9 fixed at the bottom, and the first rack plate 9 moves to rotate the external meshing spur gear 8, and the spur gear 8 rotates to move the external meshing second rack plate 10, and the second rack plate 10 moves with the upper fixed right mounting block 12, and the right mounting block 12 moves with the upper fixed right moving plate 13, and the right moving plate 13 moves with the upper fixed right fixed frame 14, so that the two fixed frames 14 move relatively. The fixed frame 14 moves with the externally fixed half-axle sleeves to move relatively, so that the two half-axle sleeves can be aligned, and the half-axle sleeves can be automatically aligned, which solves the problem that the adjustment process of the traditional alignment method through fine-tuning bolts and moving guide rails requires the operator to have a high technical level, the adjustment steps are cumbersome, and the time-consuming is long, ensuring that the concentricity accuracy reaches the best. Then, when welding the half-axle sleeves, by starting the motor 2101, the motor 2101 rotates with the first bevel gear 2102 fixed at the output end, the first bevel gear 2102 rotates with the externally meshed second bevel gear 2103, the second bevel gear 2103 rotates with the internally fixed transmission rod 2104, the transmission rod 2104 rotates with the externally fixed rotating disk 2105, and the rotating disk 2105 rotates with the externally fixed half-axle sleeves. When welding the half-axle sleeves, the half-axle sleeves can be automatically flipped over without the operator manually flipping over, which greatly shortens the operation time compared to manual flipping and improves the welding quality of the half-axle sleeves.
