Description

Technical Field

[0001] This utility model relates to the field of machining, and in particular to a wheel hub burr removal device for wheel hub manufacturing. Background Technology

[0002] The wheel hub has burrs of varying sizes at the intersection of the cast and machined surfaces after machining. If these burrs are not removed properly, they will affect the adhesion of the paint after spraying, easily resulting in paint chipping and defective products. Furthermore, the sharp burrs can easily cause scratches to personnel who come into contact with this area, posing a safety hazard. They can also cause leakage failure, affecting the appearance and protective effect of the finished product. Usually, wheel hub machining is done manually by using sandpaper to polish the surface to remove burrs.

[0003] Chinese Patent No. CN222222065U discloses a burr removal device for aluminum alloy wheel hub production. It includes a base plate with a fixed frame on top, and a screw rotatably connected inside the fixed frame. A movable plate is screwed to the wall of the screw. This invention uses the movable plate to move downwards along the fixed frame, and in conjunction with the adjustment of the polishing component position, positions the wheel hub rim between two polishing rollers, pressing a pressure block against the center of the wheel hub. A drive motor then rotates one of the polishing rollers, which in turn drives the other polishing roller to rotate via meshing gears. The rotating shaft drives a rotating mechanism to rotate around the wheel hub, thereby polishing both the outer and inner rims of the wheel hub.

[0004] While this device can achieve a certain degree of deburring effect, in actual use, when the rotating mechanism grinds around the hub, the pressure block pressed against the center of the hub needs to remain pressed to limit the hub's position. However, since the fixed rod rotates synchronously, it directly affects the sufficient pressing and limiting effect of the pressure block. In particular, when a large lateral force is generated during the grinding process, the hub is prone to vibration and slippage, affecting the positional stability of the processed hub. This results in unreliable hub limiting and support effects, leading to poor burr grinding and shaping. Utility Model Content

[0005] The purpose of this invention is to provide a wheel hub burr removal device for wheel hub manufacturing, which has the advantage of improving the stability and reliability of burr removal.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a wheel hub burr cleaning device for wheel hub manufacturing, comprising a fixed support, a vertical adjustment frame provided on the fixed support, a horizontal support plate movably connected to the vertical adjustment frame, a vertical groove provided in the vertical adjustment frame for vertical movement of the horizontal support plate, a threaded rod and a screw motor for driving the horizontal support plate to move on the vertical adjustment frame, and a rotary polishing assembly provided at the end of the horizontal support plate away from its movable connection with the vertical groove, the rotary polishing assembly comprising a support block movably connected to the horizontal support plate, a rotary drive motor fixed on the support block, and a rotary drive motor... A rotary drive shaft, rotatably connected to a support block at its end, is provided with a polishing block. The fixed support is equipped with an auxiliary limiting component, which includes a support platform detachably connected to the fixed support and multiple limiting rods on the support platform.

The auxiliary limiting component also includes a limiting disc at the end of the rotary drive shaft. The limiting disc includes a rotating disk fixed to the rotary drive shaft and an insertion disc sleeved outside the rotating disk. The insertion disc has a limiting slot that mates with the limiting rods.

[0007] Preferably, the middle part of the plug-in plate is provided with a rotating groove for the rotating disk to rotate and engage, and the thickness of the rotating disk is less than the depth of the rotating groove.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] Example: A wheel hub deburr removal device for wheel hub manufacturing, such as... Figure 1 and Figure 2 As shown, it includes a fixed support 1, a vertical adjustment frame 2 on the fixed support 1, a horizontal support plate 3 movably connected to the vertical adjustment frame 2, a vertical groove 4 in the vertical adjustment frame 2 for the vertical movement of the horizontal support plate 3, a threaded rod 5 and a screw motor 6 on the vertical adjustment frame 2 to drive the horizontal support plate 3 to move, thereby adjusting the height of the horizontal support plate 3 to flexibly adapt to the actual height of the wheel hub to be processed, and to facilitate local grinding processing.

[0019] A rotary polishing assembly is also provided at the end of the horizontal support plate 3 away from its movable connection with the vertical groove 4. The rotary polishing assembly is adjusted in real time as the vertical position of the horizontal support plate 3 moves. The rotary polishing assembly includes a support block 7 movably connected to the horizontal support plate 3, a rotary drive motor 8 fixed on the support block 7, and a rotary drive shaft 9 rotatably connected to the support block 7 at the end of the rotary drive motor 8. During the polishing process, the rotary drive motor 8 drives the rotary drive shaft 9 to rotate. A polishing block 10 is provided on the rotary drive shaft 9, thereby driving the polishing block 10 to achieve an orderly burr polishing process along the circumference of the hub. The polishing block 10 includes a connecting frame 20 fixed to the rotary drive shaft 9, a lead screw 21 rotatably connected within the connecting frame 20, a servo motor 22 driving the lead screw 21 to rotate, and a polishing block 23 threadedly connected to the wall of the lead screw 21. The polishing block 23 includes a pair of electric polishing rollers. The operator controls the servo motor 22 to move the polishing block 23 as a whole, adapting in real time to the product specifications of the wheel hub to be processed, ensuring that the pair of electric polishing rollers can simultaneously polish the burrs on the inner and outer rings of the wheel hub separately.

[0020] To improve the stability of the wheel hub during the grinding process, the fixed support 1 is equipped with an auxiliary limiting component, which can work with the rotary polishing component to stably limit the relative position of the wheel hub during grinding. The auxiliary limiting component includes a support block 11 detachably connected to the fixed support 1 and multiple limiting rods 12 provided on the support block 11. The processing personnel select the appropriate support block 11 according to the specifications of different batches of wheel hubs to be processed, so that the limiting rods 12 on the support block 11 can reliably insert and limit the wheel hub with the insertion holes, thereby restricting the movement of the wheel hub. The fixed support 1 is provided with an insertion groove 13, and the support block 11 is movably inserted into the insertion groove 13, which not only facilitates the disassembly and assembly of the support block 11, but also facilitates the grinding and assembly of the wheel hub by the processing personnel.

[0021] The auxiliary limiting component also includes a limiting plate 14 located at the end of the rotary drive shaft 9. After the wheel hub and the support plate 11 are fitted together and moved to the designated position, the limiting plate 14, along with the downward movement of the horizontal support plate 3, completes the locking with the limiting rod 12. The limiting plate 14 includes a rotating disk 15 fixed to the rotary drive shaft 9 and a plug-in plate 16 fitted outside the rotating disk 15. The plug-in plate 16 is provided with a limiting slot 17 that cooperates with the limiting rod 12, ultimately satisfying the insertion of the limiting slot 17 and the limiting rod 12, and achieving the abutment effect between the plug-in plate 16 and the center of the wheel hub. The bottom of the plug-in plate 16 is provided with an elastic damping washer 25 to improve the limiting stability of the plug-in plate 16 and the processed wheel hub.

[0022] The center of the insert plate 16 is provided with a rotating groove 18 for the rotating disk 15 to rotate and engage. The thickness of the rotating disk 15 is less than the depth of the rotating groove 18, so that when the rotary drive motor 8 drives the rotary drive shaft 9 to rotate, the rotating disk 15 rotates synchronously, achieving rotation relative to the insert plate 16. At this time, the insert plate 16 can limit the vertical runout of the processed hub and limit the horizontal displacement of the hub under sufficient clamping action. The setting of the limiting rod 12 provides a supplementary limiting effect on the horizontal movement of the hub under possible excessive vibration conditions, ensuring the precise grinding effect of the polishing roller group. The side of the vertical adjustment frame 2 is also slidably connected to a horizontal laser instrument block 24. The processing personnel adjust the position of the horizontal laser instrument block 24 according to the real-time height of the processed hub, assisting the processing personnel in judging the positional stability of the hub during the grinding process by observing the state of the horizontal laser line on the hub. Once excessive runout or other phenomena occur, the limiting clamping force of the insert plate 16 can be increased by moving the horizontal support plate 3 downward in time, ensuring consistent precision of continuous grinding.

[0023] To improve the efficiency of the wheel hub grinding and disassembly process, the bracket block 7 is rotatably connected to the horizontal support plate 3. The bracket block 7 and the horizontal support plate 3 are connected by a rotating sleeve shaft 19, which enables the bracket block 7 to rotate relative to the horizontal support plate 3, thereby driving the overall position change of the rotary polishing assembly. This ensures reliable disassembly and assembly space for the wheel hub below the horizontal support plate 3 and reduces possible interference and collision damage between equipment.

[0024] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
