Description

Technical Field

[0001] This invention belongs to the field of conical wheel hub press-fitting technology, and more specifically, relates to a conical wheel hub press-fitting device. Background Technology

[0002] During the production process, some rotors need to have conical hubs installed on their end faces. Since both the rotor and the conical hub are composite materials, they cannot be directly fixed by metal connectors. Therefore, they are usually fixed by an interference fit between the conical hub and the rotor. Specifically, the conical hub is pressed tightly onto the rotor by a press-fitting device.

[0003] During the press-fitting of conical hubs, if the hub is misaligned, causing it to be out of sync with the rotor, it will result in scrap. Therefore, this process requires high precision to ensure the coaxiality of the conical hub and rotor. Currently, a dedicated centering fixture is commonly used for centering. This fixture has a conical design and is customized according to the size and shape of the conical hub. In use, the conical hub is placed in the fixture, and the position and angle of the fixture are adjusted to make the conical hub concentric with the rotor. This method requires the fabrication of a dedicated fixture, is complex, inefficient, and costly. Summary of the Invention

Before the hub pressing begins, the rotor is first placed in the receiving groove of the rotor positioning unit. The pressing unit is then separated from the guide member, and the conical part of the hub is placed in the positioning hole of the hub positioning unit. The pressing unit is then connected to the guide member, and the pressing unit applies downward pressure to the hub. After the hub positioning unit receives the pressure transmitted by the hub, the clearance part is compressed.

[0060] Please refer to the following: Figures 1 to 4 The technical solution provided by the present invention will now be described. The present invention provides a conical wheel hub pressing device, including a frame 10, a rotor positioning unit 20, a wheel hub positioning unit 30, a pressing unit 40, and a pushing unit 50. The frame 10 includes a base 101 and a plurality of guide members 102 disposed on the base 101. The plurality of guide members 102 are parallel to each other and are arranged in the vertical direction. The rotor positioning unit 20 is slidably connected to the plurality of guide members 102 in the vertical direction. The rotor positioning unit 20 has a receiving groove 2011 adapted to the outer peripheral surface of the rotor 60. The rotor positioning unit 20 is used to apply an upward force to the rotor 60. The hub positioning unit 30 is located on the upper part of the rotor positioning unit 20. The hub positioning unit 30 has a relief part that extends and retracts in a vertical manner and a positioning hole 3023-2 opened in the vertical direction. The positioning hole 3023-2 is coaxially arranged with the receiving groove 2011. The pressing unit 40 is located above the hub positioning unit 30. The pressing unit 40 is slidably connected to multiple guide members 102 in the vertical direction. The pressing unit 40 is used to apply downward pressure to the hub 70. The pushing unit 50 is located on the base 101 and below the rotor positioning unit 20. The pushing unit 50 is used to apply upward pushing force to the rotor positioning unit 20.

[0061] This invention provides a conical wheel hub pressing device. Compared with the prior art, this invention's wheel hub pressing device can automatically ensure the coaxiality of the wheel hub 70 and the rotor 60. Before pressing the wheel hub 70 begins, the rotor 60 is first placed in the receiving groove 2011 of the rotor positioning unit 20. The pressing unit 40 is first separated from the guide member 102, and the conical part of the wheel hub 70 is placed in the positioning hole 3023-2 of the wheel hub positioning unit 30. Then, the pressing unit 40 is connected to the guide member 102, and the pressing unit 40 applies downward pressure to the wheel hub 70. After the wheel hub 70 receives the pressure transmitted by the wheel hub 70, the clearance part of the wheel hub positioning unit 30 is compressed. Since the conical part of the wheel hub 70 is inserted into the positioning hole 3023-2, the wheel hub 70 moves radially under pressure to become coaxial with the positioning hole 3023-2, thereby achieving centering adjustment of the wheel hub 70 and making the wheel hub 70 coaxial with the rotor 60. Finally, the jacking unit 50 applies an upward thrust to the rotor positioning unit 20, causing the rotor 60 to press the hub 70 upward, pressing the hub 70 to a specified depth inside the rotor 60, thus completing the press-fitting process of the hub 70. The solution in this invention can automatically ensure the coaxiality of the hub 70 and the rotor 60 when fixing the hub 70, eliminating the need for special fixtures, simplifying the process of ensuring the coaxiality of the hub 70 and the rotor 60, improving production efficiency, and reducing costs.

[0062] Optionally, the distribution path of the multiple guide elements 102 can be one of a ring, arc, curve or other polygon, or other shapes.

[0063] Optionally, the guide member 102 has a limiting hole 1021 at its bottom. The frame 10 also includes multiple shaft assemblies 103 and limiting pins 104 sleeved on the bottom of the guide member 102. The shaft assemblies 103 are arranged one-to-one with the guide members 102. The shaft assemblies 103 are located between the rotor positioning unit 20 and the base 101. The shaft assemblies 103 have limiting grooves 1031 corresponding to the limiting holes 1021. The limiting pins 104 are inserted into the limiting grooves 1031 and the limiting holes 1021. By setting the shaft assemblies 103 between the rotor positioning unit 20 and the base 101 to support the rotor positioning unit 20, the guide member 102 does not need to have a structure for supporting the rotor positioning unit 20 during material selection and processing, thus saving material costs.

[0064] In some embodiments, please refer to Figure 4 and Figure 5The pressing unit 40 includes a pressing cover 401, a locking component 402, and a driving component 403. The pressing cover 401 is slidably connected to a plurality of guide members 102. The locking component 402 includes a plurality of locking buckles 4021 disposed on the top of the pressing cover 401. The locking buckles 4021 are correspondingly disposed to the guide members 102 one by one. The locking buckles 4021 are rotatably connected to the pressing cover 401. The locking buckles 4021 have a locked state that is hooked with the guide member 102 and an unlocked state that is separated from the guide member 102. The driving component 403 is connected to at least one of the guide members 102 and is used to control the pressing cover 401 to slide in the up and down direction.

[0065] With the locking buckle 4021 in the unlocked state separated from the guide member 102, the drive assembly 403 is controlled to slide the cover 401 upwards. The cover 401 is rotated to place the rotor 60 and the hub 70 on the designated working surface. The cover 401 is installed along the guide member 102, and the locking buckle 4021 is placed in the locked state hooked with the guide member 102, thus completing the fixation of the rotor 60 and the hub 70. This scheme only applies pressure to the upper surface of the hub 70, which allows the conical base 101 of the hub 70 to adapt to the positioning cylinder 3023, ensuring the coaxiality of the hub 70 and the rotor 60.

[0066] Optionally, the axial height of the guide 102 connected to the drive assembly 403 is greater than that of other guides 102, to prevent the gland 401 from completely detaching from the guide 102 and to improve adjustment efficiency.

[0067] Optionally, an anti-slip washer 4011 is provided below the cover 401 to increase the friction between the wheel hub 70 and the cover 401 and prevent the wheel hub 70 from slipping off.

[0068] Optionally, the guide member 102 has a locking groove 1022 that is adapted to the locking buckle 4021. When the locking buckle 4021 is engaged in the locking groove 1022, the locking buckle 4021 is in a locked state.

[0069] Optionally, a connector 404 is provided below the drive component 403 to support the drive component 403.

[0070] In some embodiments, please refer to Figure 5 The drive assembly 403 includes a guide post 4032 and a drive sleeve 4031. The guide post 4032 is disposed outside the guide member 102. The drive sleeve 4031 is sleeved outside the guide member 102. The drive sleeve 4031 has a spiral groove 4031-1 around its own axis, and the guide post 4032 is inserted into the groove 4031-1.

[0071] Rotating the drive sleeve 4031 causes the guide column 4032 to slide within the slide groove 4031-1 of the drive sleeve 4031, which allows the drive sleeve 4031 to move upward, thereby pushing the pressure plate to slide upward along the guide member 102. This solution can eliminate the process of manually moving the pressure plate directly, thus improving the operational safety of the device.

[0072] Optionally, a handle 4033 is connected to the outside of the drive sleeve 4031. The operation of the handle 4033 can drive the drive sleeve 4031 to rotate. By setting the handle 4033, the torque required to rotate the drive sleeve 4031 can be reduced, making it easier to operate.

[0073] Optionally, the drive assembly 403 also includes a connecting sleeve 4034 disposed above the drive sleeve 4031. By rotating the drive sleeve 4031 to drive the connecting sleeve 4034 to rise, the processing height of the drive sleeve 4031 can be reduced during processing, thus saving costs.

[0074] In some embodiments, please refer to Figure 4 The hub positioning unit 30 includes a support member 301 and an adjustment component 302. The support member 301 is disposed on the rotor positioning unit 20 and is located in the middle of a plurality of guide members 102. The axis of the support member 301 is parallel to the axis of the guide members 102. The adjustment component 302 is disposed on the top of the support member 301. The adjustment component 302 has a centering groove 3021 in the vertical direction. The centering groove 3021 is used to center the hub 70. The adjustment component 302 can extend and retract in the vertical direction and forms a clearance part.

[0075] Support member 301 supports adjustment assembly 302. The hub 70 extends and retracts along the vertical direction on the adjustment assembly 302. Automatic centering is achieved by the radial sliding of the conical portion of the hub 70 within the centering groove 3021 until it is coaxial with the positioning hole 3023-2. This solution utilizes the conical portion of the hub 70 for automatic centering, eliminating the need to manufacture a dedicated centering fixture for the hub 70 and improving the efficiency of hub 70 press-fitting.

[0076] In some embodiments, please refer to Figure 4 and Figure 8 The adjusting assembly 302 includes a fixed base 3022, a positioning cylinder 3023, and a plurality of elastic telescopic members 3024. The fixed base 3022 includes a fixed part and a connecting part located on the top of the fixed part. The fixed part covers the top of the support member 301, and the connecting part is recessed within the fixed part, so that the fixed part and the connecting part form a stepped structure. The fixed part is adapted to the through hole of the rotor 60. The positioning cylinder 3023 is slidably sleeved outside the connecting part. The plurality of elastic telescopic members 3024 are distributed in a ring outside the connecting part, and the elastic telescopic members 3024 are configured with a preload force to move the positioning cylinder 3023 upward.

[0077] The positioning cylinder 3023 is fitted onto the connecting part of the fixed base 3022. Under the action of the elastic telescopic member 3024, the positioning cylinder 3023 slides up and down along the outer periphery of the connecting part of the fixed base 3022, forming a clearance part to center the hub 70. The fixed part is adapted to the through hole of the rotor 60, so that the hub 70 and the rotor 60 are coaxial. This design allows the positioning cylinder 3023 to slide up and down along a fixed trajectory, improving the coaxiality of the hub 70 and the rotor 60.

[0078] In some embodiments, please refer to Figure 11 The positioning cylinder 3023 has a first guide hole 3026 in the vertical direction, and the connecting part has a second guide hole 3027 corresponding to the first guide hole 3026. The elastic telescopic member 3024 includes a guide rod 3024-1 and an elastic member 3024-2. The guide rod 3024-1 is inserted into the first guide hole 3026 and the second guide hole 3027 respectively. The elastic member 3024-2 is sleeved on the guide rod 3024-1 and is configured with a preload to move the connecting part away from the positioning cylinder 3023.

[0079] Inserting the elastic element 3024-2 into the first guide hole 3026 and sleeved on the guide rod 3025 allows the elastic element 3024-2 to drive the connecting part to extend and retract along a fixed trajectory, avoiding deformation of the elastic element 3024-2 in other directions, which would affect the movement trajectory of the connecting part. This solution improves the reliability of the hub positioning unit 30.

[0080] Optionally, the guide rod 3024-1 includes a guide portion and a limiting portion provided at the top of the guide portion. The bottom of the second guide hole 3027 is provided with a third guide hole 3028 that is adapted to the limiting portion. The limiting portion is used to prevent the guide rod 3024-1 from slipping out of the second guide hole 3027.

[0081] Optionally, the elastic element 3024-2 is a spring.

[0082] In some embodiments, please refer to Figure 1 and Figure 9 The rotor positioning unit 20 includes a positioning disk 201 that is slidably connected to a plurality of guide members 102, and the positioning disk 201 is provided with a receiving groove 2011.

[0083] By setting the positioning plate 201 to support the rotor 60, and only applying constraints to the bottom surface of the rotor 60, the top of the rotor 60 and the conical part of the hub 70 can slide radially to complete the coaxial pressing. At the same time, the positioning plate 201 pushes the rotor 60 upward to complete the pressing, so that the rotor 60 is subjected to uniform force and moves upward smoothly to complete the pressing.

[0084] In some embodiments, please refer to Figure 1 and Figure 7The rotor positioning unit 20 also includes a limiting ring 303 and a washer 202. The limiting ring 303 is located in the receiving groove 2011, and the support member 301 is inserted into the limiting ring 303. The washer 202 is located on the top of the limiting ring 303 and is used to protect the bottom of the rotor 60.

[0085] The support 301 can be fixed by setting the limit ring 303, which reduces the processing difficulty and cost of the support 301. The washer 202 can protect the bottom of the rotor 60 and prevent wear caused by the sliding of the rotor 60.

[0086] In some embodiments, please refer to Figure 1 and Figure 4 The push unit 50 includes a first driver 502 and a push member 501. The first driver 502 is located on the top of the base 101 and extends and retracts in the vertical direction. The push member 501 is connected to the extension end of the first driver 502.

[0087] The first driver 502 drives the pusher 501 to push the positioning disk 201, thus completing the press-fitting of the hub 70 into the rotor 60. In this embodiment, the solution can provide uniform pressure, making the press-fitting of the hub 70 more stable and avoiding the hub 70 from becoming skewed and producing defective parts.

[0088] Optionally, the first actuator 502 is a hydraulic cylinder.

[0089] In some embodiments, please refer to Figure 7 , Figure 8 and Figure 12 The fixed base 3022 has a connecting hole 3022-1, the hub positioning unit 30 also includes a connecting pin 3022-2, the positioning cylinder 3023 has a connecting groove 3023-1 adapted to the connecting pin 3022-2, and the connecting pin 3022-2 is inserted into the connecting hole 3022-1 and the connecting groove 3023-1.

[0090] By inserting the connecting pin 3022-2 into the connecting hole 3022-1 and the connecting groove 3023-1, the fixed seat 3022 and the positioning cylinder 3023 can be connected, which can increase the stability of the hub positioning unit 30 during press fitting.

[0091] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
