Description

Technical Field

[0001] This utility model relates to the field of axle assembly technology, specifically to an anti-rolling positioning device for axle assembly. Background Technology

[0002] As a core component of a vehicle's transmission system, the assembly precision of the axle directly affects the vehicle's driving stability, safety, and service life. During axle assembly, precise positioning is required to ensure the connection accuracy between the axle and other components (such as wheel hubs and suspension systems). However, axles are typically long-shaft parts, and their weight and shape can easily cause rolling or displacement during assembly, making assembly operations difficult and even posing safety hazards.

[0003] However, existing anti-roll positioning devices for axle assembly still have some problems in use:

[0004] First, the positioning spacing of existing positioning devices is mostly designed to be fixed, which makes it difficult to adapt to the positioning needs of axles of different sizes. Since different axles have different sizes, the positioning spacing needs to be flexibly adjusted in order to better position the axles. Fixed positioning spacing cannot adapt to different positioning situations, thus reducing the adaptability of the positioning device.

[0005] Secondly, the positioning plates in existing positioning devices are generally fixed in position. However, the process reference points of the axle vary, and the fixed positioning plates cannot be flexibly adjusted in relative position according to the actual fixing requirements of the axle, thus reducing the flexibility of the positioning device. Utility Model Content

[0006] In order to solve the problems of fixed positioning spacing and inability to freely adjust the relative position of positioning plates in existing positioning devices, the purpose of this utility model is to provide an anti-rolling positioning device for vehicle axle assembly.

[0007] To solve the above technical problems, the present invention adopts the following technical solution: a positioning device for anti-rolling in axle assembly, comprising a base, a placement platform above the base, a clamping mechanism on the upper surface of the placement platform, a connecting sleeve on the upper surface of the clamping mechanism, a positioning mechanism on one side of the connecting sleeve, the clamping mechanism comprising a DC motor, the DC motor being fixedly installed on one side of the placement platform, the output end of the DC motor passing through the placement platform and fixedly connected to a bidirectional screw, and a slider being threaded on the outer surface of the bidirectional screw, the upper surface of the slider being fixedly connected to the connecting sleeve.

[0008] Preferably, the positioning mechanism includes a sliding plate, which is slidably connected to the inside of the connecting sleeve. The connecting sleeve and one side of the sliding plate are threadedly connected with a positioning bolt. A horizontal block is fixedly connected to one side of the sliding plate, and a positioning plate is fixedly connected to the side of the horizontal block facing away from the sliding plate. A silicone pad is fixedly connected to one side of the positioning plate.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. This application uses a clamping mechanism to flexibly adjust the positioning distance electrically, so that the positioning device can adapt to different axle positioning. Compared with the traditional fixed positioning distance, it can effectively improve the adaptability of the positioning device and better stabilize the axle during assembly.

[0011] 2. This application uses an adjustable positioning mechanism to flexibly adjust the relative position of the positioning plate according to the shape of the axle, so that the positioning plate can fit into a convenient positioning position on the axle surface, which significantly improves the flexibility of the positioning device and the stability of positioning.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Figure 1-3 As shown, this utility model provides an anti-rolling positioning device for axle assembly, including a base 1. A placement platform 9 is provided above the base 1. A cylinder 4 is fixedly installed on the upper surface of the base 1, and the output end of the cylinder 4 is fixedly connected to the lower surface of the placement platform 9. The placement platform 9 is driven to rise and fall by the cylinder 4, which can flexibly adjust the axle assembly height to adapt to the positioning requirements of axles of different sizes. A guide sleeve 5 is fixedly connected to the upper surface of the base 1 in a rectangular array. A guide rod 7 is slidably connected inside the guide sleeve 5, and the top end of the guide rod 7 is fixedly connected to the placement platform 9. The cooperation between the guide sleeve 5 and the guide rod 7 provides stable linear motion guidance for the placement platform 9, avoiding deviation or shaking during the lifting process and ensuring the positioning accuracy of the axle.

[0019] The upper surface of the placement platform 9 is provided with a clamping mechanism 2, and the upper surface of the clamping mechanism 2 is provided with a connecting sleeve 8. The clamping mechanism 2 is used to fix the axle and facilitates flexible adjustment of the positioning distance to ensure the positioning effect of the axle. A positioning mechanism 3 is provided on one side of the connecting sleeve 8. The adjustable positioning mechanism 3 facilitates the improvement of the flexibility of the positioning device.

[0020] The clamping mechanism 2 includes a DC motor 26, which is fixedly mounted on one side of the placement platform 9. A mounting base 25 for use with the DC motor 26 is fixedly mounted on one side of the placement platform 9. The DC motor 26 is fixedly mounted on the upper surface of the mounting base 25, which enhances the installation stability of the DC motor 26. The output end of the DC motor 26 passes through the placement platform 9 and is fixedly connected to a bidirectional screw 23, which facilitates the output end of the DC motor 26 to drive the bidirectional screw 23 to rotate. A rectangular groove 24 is provided on the upper surface of the placement platform 9. One end of the bidirectional screw 23 is rotatably connected to the rectangular groove 24. The rectangular groove 24 provides a stable rotation base point for the bidirectional screw 23. A slider 22 is threaded on the outer surface of the bidirectional screw 23, which facilitates the rotation of the bidirectional screw 23 to drive the slider 22 to move.

[0021] The inner wall of the rectangular groove 24 is symmetrically provided with limiting grooves 21 for use with the slider 22. The slider 22 is slidably connected to the limiting grooves 21. The limiting grooves 21 serve to limit the movement position of the slider 22. The slider 22 is threaded on the opposite thread direction provided on the outer surface of the bidirectional screw 23. The reverse thread design allows the two sliders 22 to move synchronously and symmetrically, ensuring uniform force on the axle. The upper surface of the slider 22 is fixedly connected to the connecting sleeve 8, which facilitates the movement of the slider 22 to drive the connecting sleeve 8 to move. This allows for flexible adjustment of the positioning distance of the positioning device and improves its adaptability.

[0022] The positioning mechanism 3 includes a sliding plate 35, which is slidably connected to the interior of the connecting sleeve 8. The interior of the connecting sleeve 8 has a guide groove 31 for use with the sliding plate 35. The sliding plate 35 is slidably connected to the guide groove 31. The cooperation between the guide groove 31 and the sliding plate 35 allows the positioning mechanism 3 to slide along the axle axis, realizing flexible adjustment of the positioning position. The connecting sleeve 8 and the sliding plate 35 are threadedly connected to one side with a positioning bolt 33. The connecting sleeve 8 has a first positioning hole 32 at equal intervals on one side, and the sliding plate 35 has a second positioning hole 34 on one side. The positioning bolt 33 is threadedly connected to the corresponding first positioning hole 32 and second positioning hole 34. The cooperation between the positioning bolt 33 and the first positioning hole 32 and the second positioning hole 34 can lock the position of the sliding plate 35 to adapt to the positioning requirements of different axles.

[0023] A horizontal block 36 is fixedly connected to one side of the slide plate 35, and a positioning plate 37 is fixedly connected to the side of the horizontal block 36 facing away from the slide plate 35. The positioning plate 37 is connected to the slide plate 35 through the horizontal block 36. A silicone pad 38 is fixedly connected to one side of the positioning plate 37. The silicone pad 38 increases the friction with the axle, prevents the axle from rolling and protects its surface, thereby facilitating flexible adjustment of the relative position of the positioning plate 37 so that the positioning device can stably position the axle.

[0024] Working principle: First, place the axle on the placement platform 9, start the cylinder 4, and its output end pushes the placement platform 9 to rise and fall vertically along the linear guide rail system composed of the guide sleeve 5 and the guide rod 7, and adjust it to a suitable assembly height. The cooperation between the guide sleeve 5 and the guide rod 7 ensures that the placement platform 9 moves stably.

[0025] Next, the relative position of the positioning plate 37 is adjusted according to the shape of the axle by the positioning mechanism 3. The sliding plate 35 is slid to move along the axle axis in the guide groove 31 of the connecting sleeve 8 to adjust the position of the positioning plate 37. When the second positioning hole 34 of the sliding plate 35 is aligned with the first positioning hole 32 of the connecting sleeve 8, the positioning bolt 33 is tightened to fix the sliding plate 35, so that the sliding plate 35 is adjusted to the appropriate position by the positioning plate 37 connected by the cross block 36.

[0026] Next, the DC motor 26 is started through the clamping mechanism 2, and its output end drives the bidirectional screw 23 to rotate. The reverse threads at both ends of the bidirectional screw 23 cause the slider 22 to slide towards each other in the rectangular groove 24 along the limiting groove 21. The limiting groove 21 plays a role in limiting the movement position of the slider 22. The movement of the slider 22 drives the connecting sleeve 8 to move.

[0027] The moving connecting sleeve 8 causes the silicone pad 38 on the positioning plate 37 to contact the axle, fixing the axle and using friction to prevent the axle from rolling and protect its surface.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
