[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0024] Reference Figure 1 - Figure 2 The utility model provides an embodiment: a dividing plate flatness correction device for sprocket shaft group processing, comprising a fixed base 1, a sprocket shaft 2 is arranged on the upper surface of the fixed base 1, a sprocket 3 is arranged on the outer wall of the sprocket shaft 2, an external spline 4 is arranged on the top of the sprocket shaft 2, a dividing plate 5 is arranged on the top of the sprocket shaft 2, an internal spline 6 is fixedly connected to the inner wall of the dividing plate 5, the external spline 4 is meshed with the internal spline 6, a motor 7 is fixedly connected to the inside of the fixed base 1, a gear 8 is fixedly connected to the output end of the motor 7, a gear ring 9 is rotatably connected to the inside of the fixed base 1, the gear 8 is meshed with the gear ring 9, a storage assembly is arranged on the inner wall of the gear ring 9, and the storage assembly comprises a loading plate 10, the outer wall of the loading plate 10 is fixedly connected to the inner wall of the gear ring 9, the loading plate 10 is fitted with the sprocket shaft 2, and the outer wall of the loading plate 10 is rotatably connected to the inside of the fixed base 1;

[0025] Specifically, first, place the sprocket shaft 2 at the center of the base to ensure that the sprocket shaft 2 is firmly placed on the base, then take out the dividing plate 5. The dividing plate 5 is designed so that its top angle is the same as the number of teeth of the sprocket 3. Align the top angle of the dividing plate 5 with the teeth of the sprocket 3 to ensure subsequent processing accuracy. At the same time, the inner spline 6 in the middle of the dividing plate 5 matches the outer spline 4. Ensure that the inner spline 6 is fully aligned with the outer spline 4, and then insert it accurately so that the dividing plate 5 and the sprocket shaft group are tightly connected together. Each top angle of the dividing plate 5 can be accurately aligned with each tooth of the sprocket 3, and then start the motor 7. The output end of the motor 7 is connected to the gear 8. When the motor 7 starts working, it will drive the gear 8 to rotate. Due to the meshing relationship between the gear 8 and the gear ring 9 , the gear ring 9 will rotate with the rotation of the gear 8. The gear ring 9 is connected to the loading plate 10, so the loading plate 10 will also rotate with the rotation of the gear 8, and the sprocket shaft group will be driven and start to rotate. During the rotation of the sprocket shaft group, an external right-angle ruler or dial indicator must be used to ensure that the front of the dividing plate 5 is completely in contact with the processing surface. If a dial indicator is used, the probe of the dial indicator can be placed on the front of the dividing plate 5, and then the reading of the dial indicator can be observed. The position of the dividing plate 5 can be adjusted to make the reading reach the best state. When the front of the dividing plate 5 is completely in contact with the processing surface, the processing of the sprocket shaft begins. In this process, due to the precise alignment of the dividing plate 5 and the stable rotation of the sprocket shaft group, very high processing accuracy and product quality can be obtained.

[0026] Reference Figure 1 , Figure 3 and Figure 4 The interior of the fixed base 1 is fixedly connected with a cylinder 12, the output end of the cylinder 12 is fixedly connected with a slide plate 13, the upper surface of the slide plate 13 is fixedly connected with a triangular support 14, the outer wall of the triangular support 14 is fixedly connected with a clamping plate 15, the outer wall of the clamping plate 15 is fixedly connected to the outer wall of the slide plate 13, a ball 16 is arranged inside the clamping plate 15, the bottom of the slide plate 13 is fixedly connected with a fixed plate 17, the interior of the fixed plate 17 is rotatably connected with a connecting rod 18, a section of the connecting rod 18 is slidably connected to the interior of 1, the outer wall of the slide plate 13 is slidably connected to the interior of the fixed base 1, a slide groove 11 is opened inside the fixed base 1, a section of the connecting rod 18 is rotatably connected to a cross rotating frame 19, and the outer wall of the cross rotating frame 19 is rotatably connected to the interior of the fixed base 1;

[0027] Specifically, the output end of the cylinder 12 is connected to the slide plate 13. When the cylinder 12 is started, its output end pushes the slide plate 13 to rotate inside the fixed base 1. The slide plate 13 is connected to the clamping plate 15 and the fixing plate 17. Therefore, when the slide plate 13 rotates, the clamping plate 15 and the fixing plate 17 will also move accordingly. The movement of the fixing plate 17 will further drive one end of the connecting rod 18 connected thereto to move. The other end of the connecting rod 18 is connected to the cross rotating frame 19. Therefore, when the connecting rod 18 moves, it will push the cross rotating frame 19 to rotate inside the fixed base 1. The cross rotating frame 19 is connected to the four connecting rods 18. When the cross rotating frame 19 rotates, it will drive the other three connecting rods 18 to rotate synchronously. In this way, the four clamping plates 15 can move synchronously, thereby realizing the clamping and positioning of the sprocket shaft group. The triangular support 14 plays an additional supporting role, ensuring the stability and reliability of the clamping and positioning process.

[0028] Working principle: When the indexing plate flatness correction device for sprocket shaft assembly processing is needed, first place the sprocket shaft 2 at the center of the fixed base 1, then take out the indexing plate 5, align the top angle of the indexing plate 5 with the teeth of the sprocket 3, and at the same time align the inner spline 6 in the middle of the indexing plate 5 with the outer spline 4 and insert it accurately so that each top angle of the indexing plate 5 can be aligned with each tooth of the sprocket 3, then drive the gear 8 to rotate through the output end of the motor 7, due to the meshing of the gear 8 and the gear ring 9, the gear ring 9 drives the carrier plate 10 to rotate with the rotation of the gear 8, thereby driving the sprocket shaft assembly to rotate, then use the external right-angle ruler to find the front side flush with the indexing plate 5, or use a dial indicator The dividing plate 5 can be processed directly by simply straightening it up and down on the front side. During this process, the slide plate 13 is driven to rotate inside the fixed base 1 through the output end of the cylinder 12, thereby driving the clamping plate 15 and the fixed plate 17 to move. The movement of the fixed plate 17 drives one end of the connecting rod 18 to move, and then the other end of the connecting rod 18 pushes the cross rotating frame 19 to rotate inside the fixed base 1. The rotation of the cross rotating frame 19 drives the other three connecting rods 18 to rotate synchronously, so that the four clamping plates 15 move synchronously to clamp and position the sprocket shaft group. In this process, the triangular support 14 is used for additional support to achieve the effect of positioning the sprocket shaft group.
