Technical Field

[0001] This application relates to the field of parts processing technology, and in particular to a half-shaft sleeve positioning device. Background Technology

[0002] The axle sleeve is a key component of the automotive drive axle, used to fix the axial position of the wheels, transmit road reaction forces, and support the weight of the vehicle frame.

[0003] Regarding the aforementioned technologies, the inventors believe the following problems still exist: First, when processing the axle sleeve, it needs to be positioned. However, some existing positioning devices may not be accurate when positioning the axle sleeve, causing the axle sleeve to tilt and reducing the subsequent processing effect.

[0004] Secondly, some existing devices, in order to achieve faster speed when fixing the half-shaft sleeve, usually amplify the displacement speed of the clamp, which makes it difficult to control the accuracy and reduces the stability.

[0005] To address the aforementioned problems, the inventors have proposed a half-shaft sleeve positioning device to solve these issues. Utility Model Content

[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 a half-shaft sleeve positioning device, including a base plate 1, which is used as a support member to support the device.

[0019] The top surface of the base plate 1 is fixedly installed with a positioning component 2 and multiple limiting mechanisms 3. The positioning component 2 can be used to position the half-shaft pipe. By using the first positioning block 25 and the second positioning block 22, which are relatively arranged and are both conical, the half-shaft sleeve can be radially positioned to reduce its errors.

[0020] The threaded rod of the limiting mechanism 3 drives the extrusion block 34 and the fixed block 36 to cooperate in transmission, which can achieve the effect of speed reduction and range extension, thereby making the accuracy of the half shaft sleeve better controlled and improving the positioning accuracy.

[0021] The positioning component 2 is located between multiple limiting mechanisms 3, so that the limiting mechanisms 3 and the positioning mechanism 2 can be used together.

[0022] The positioning component 2 includes a first positioning block 25, a fixing ring 26 and a support rod 21. A groove 27 is provided on the top surface of the base plate 1. The first positioning block 25 and the fixing ring 26 are both fixedly installed inside the groove 27. The first positioning block 25 is lower than the top surface of the base plate 1 so as to position the half shaft sleeve.

[0023] Furthermore, the fixing ring 26 is located inside the first positioning block 25. The fixing ring 26 can hold the support rod 21. Multiple electric telescopic rods 24 are fixedly installed at the bottom end of the support rod 21. The electric telescopic rods 24 can be remotely controlled to extend and retract.

[0024] Multiple electric telescopic rods 24 are arranged in a circular array to better fix the support rod 21. The telescopic ends of the multiple electric telescopic rods 24 are inserted into the inner wall of the fixing ring 26. The fixing ring 26 has multiple slots inside that cooperate with the electric telescopic rods 24 to fix the support rod 21 and prevent it from moving.

[0025] The top of the support rod 21 moves through the first positioning block 25 and is slidably mounted with the second positioning block 22. Both the first positioning block 25 and the second positioning block 22 are tapered and are distributed relative to each other, which can position the hollow half-shaft sleeve and perform radial positioning on it.

[0026] The top surface of the second positioning block 22 is fitted with a knob 23. The knob 23 is threaded onto the upper outer surface of the support rod 21. When the knob 23 is rotated, it will press the second positioning block 22, thereby positioning the half shaft sleeve.

[0027] The limiting mechanism 3 includes a support shell 35, which is used as a housing. The support shell 35 is fixedly installed on the top surface of the base plate 1 to prevent it from falling off.

[0028] Multiple support shells 35 are arranged in a ring array around the support rod 21 to fix the half-shaft sleeve on the outer surface of the support rod 21.

[0029] A threaded rod 32 is threadedly inserted into the top surface of the support shell 35, and a handwheel 31 is fixedly installed on the top surface of the threaded rod 32, which can better rotate the threaded rod 32.

[0030] A pressing block 34 is rotatably mounted on the bottom end of the threaded rod 32. The pressing block 34 has a trapezoidal cross section and can press the fixed block 36 to move.

[0031] The extrusion block 34 is slidably installed on one side of the inner wall of the support shell 35. One side of the extrusion block 34 is provided with an inclined surface, and the fixed block 36 is attached to the side of the extrusion block 34 with the inclined surface, so that the fixed block 36 can be moved by extrusion.

[0032] The fixing block 36 is slidably installed on the top surface of the base plate 1. A rubber pad 37 is fixedly installed on the side of the fixing block 36 near the support rod 21. The rubber pad 37 can adapt to the shape of the outer surface of the half shaft sleeve and increase the friction against it.

[0033] A limiting plate 33 is fixedly installed inside one side of the support shell 35, and one side of the extrusion block 34 is slidably installed with the limiting plate 33. The limiting plate 33 can prevent the extrusion block 34 from shifting.

[0034] A slider 38 is fixedly installed on the bottom surface of the fixed block 36, and a groove is provided on the top surface of the base plate 1 to cooperate with the slider 38. The slider 38 can limit the fixed block 36 to prevent it from shifting.

[0035] Working principle: First, the device is installed using the base plate 1. Then, multiple electric telescopic rods 24 can be wired through the space inside the support rod 21. When the positioning component 2 is needed, the support rod 21 is inserted into the fixing ring 26, and multiple electric telescopic rods 24 are activated to extend and insert into the slots, thereby fixing the support rod 21. Then, the half-shaft sleeve is fitted onto the outer surface of the support rod 21, with its bottom end located in the groove 27 on the top surface of the base plate 1, and simultaneously positioned on the outer conical surface of the first positioning block 25. Then, the second positioning block 22 is inverted and fitted onto the outer surface of the support rod 21, so that its outer conical surface presses against the half-shaft sleeve. Then, the knob 21 is screwed on and rotated, causing the knob 21 to drive the second positioning block 22, which in turn presses against the half-shaft sleeve, thereby completing the radial positioning of the half-shaft sleeve.

[0036] Then, multiple limiting mechanisms 3 are used to limit it. The handwheel 31 is turned so that the handwheel 31 drives the threaded rod 32 to rotate. The threaded rod 32 drives the extrusion block 34 to move, so that the extrusion block 34 slides through the limiting plate 33 and extrudes the fixing block 36 through the inclined plane. The fixing block 36 slides on the top surface of the base plate 1 through the slider 38. Multiple fixing blocks 36 will fix the half shaft sleeve through the rubber pad 37. When it is necessary to remove the support rod 21, after the half shaft sleeve is fixed, multiple electric telescopic rods 24 can be activated to retract it, so that the support rod 21 can be removed.

[0037] 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.
