Description

Technical Field

[0001] This utility model relates to the field of wheel hub processing technology, and in particular to a deburring device for motorcycle front wheel hubs. Background Technology

[0002] In the manufacturing and repair process of motorcycle wheels, the deburring process for the front wheel hub plays a crucial role. This step mainly addresses imperfections such as burrs and flash generated during machining or casting. By precisely removing these excess materials, the machining accuracy of the wheel hub can be significantly improved, ensuring that its various dimensional parameters meet strict standards; effectively enhancing the safety of the wheel hub under complex working conditions and reducing the potential risk of failure caused by burrs; at the same time, it greatly improves the appearance quality of the wheel hub, making its surface smoother and flatter, showcasing a high-quality aesthetic.

[0003] For example, the utility model patent CN221560743U discloses a deburring fixture for magnesium alloy wheels. The fixture describes a process where "a motor drives a grinding disc to rotate, and through the downward extension of a cylinder, a frame moves downward, causing the motor and grinding disc to follow the frame downward, bringing the grinding disc into contact with the surface of the magnesium alloy wheel and performing grinding." However, this wheel grinding process has limitations when the grinding disc deburrs the wheel surface. Given that the grinding disc has a fixed diameter and its grinding position is located in the concave area of ​​the wheel hub, this specific structure and size result in significant operational inconvenience when deburring wheels of different diameters. Even if different sized grinding discs are used to accommodate different wheel hubs, frequent disc changes in practice involve cumbersome disassembly and installation, as well as the need for adjustment and calibration of the replaced grinding disc, making the entire process complex, time-consuming, and labor-intensive.

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: a deburring device for a motorcycle front wheel hub, comprising a base frame, the surface of which is provided with multiple limiting grooves, a clamping mechanism installed at the bottom of the base frame, multiple clamping ends of the clamping mechanism passing through the limiting grooves and slidably engaging with the limiting grooves, a frame body fixedly connected to the upper end of the base frame, a lifting mechanism installed at the upper end of the frame body, a rotating mechanism fixedly connected to the lower end of the lifting mechanism, a deburring mechanism fixedly connected to the lower end of the rotating mechanism, and two polishing ends of the deburring mechanism being staggered and capable of relative movement.

[0005] As an improvement to the above technical solution, the deburring mechanism includes a slide rail, a bidirectional lead screw, a knob, a slider, a brush bar, and a locking assembly.

The lower ends of both sliders are fixedly connected to brush bars, and the two brush bars are staggered.

[0006] As an improvement to the above technical solution, the locking component includes a threaded block, a stop block, and a fixing block. The threaded block is fixedly connected to the shaft end of the bidirectional lead screw, and a fixing block is fixedly connected to one end of the threaded block. A stop block is threadedly connected to the surface of the threaded block.

[0007] As an improvement to the above technical solution, the clamping mechanism includes a motor, a lead screw, a lifting block, a hinge plate, a locking block, and a clamping plate. The motor is installed at the bottom of the base frame. The output end of the motor is fixedly connected to the lead screw. The lifting block is threadedly connected to the surface of the lead screw. The locking block is slidably engaged inside the limiting groove. The clamping plate is fixedly connected to the upper end of the locking block.

[0009] As an improvement to the above technical solution, the rotating mechanism includes a mounting plate, a second motor, a rotating plate, an annular slide, a rotating ring, and a rotating rod.

[0010] The beneficial effects of this utility model are:

[0011] When the polishing diameter of the deburring mechanism needs to be adjusted, the user only needs to turn the knob to drive the two sliders to slide smoothly along the slide rail. As the sliders slide, they will drive the two brushes to move in a staggered manner. This staggered movement design can flexibly change the polishing diameter of the deburring mechanism according to the diameter of the wheel hub to be processed. Whether it is increased or decreased, it can be achieved.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0020] Please see Figure 1-6This utility model provides a technical solution: a deburring device for a motorcycle front wheel hub, including a base frame 1, a plurality of limiting grooves 2 are formed on the surface of the base frame 1, a clamping mechanism 3 is installed at the bottom of the base frame 1, a plurality of clamping ends of the clamping mechanism 3 respectively pass through the limiting grooves 2 and are slidably engaged with the limiting grooves 2, a frame body 4 is fixedly connected to the upper end of the base frame 1, a lifting mechanism 5 is installed at the upper end of the frame body 4, a rotating mechanism 6 is fixedly connected to the lower end of the lifting mechanism 5, a deburring mechanism 7 is fixedly connected to the lower end of the rotating mechanism 6, and the two polishing ends of the deburring mechanism 7 are staggered and can move relative to each other.

[0021] In this implementation scheme, when the user starts the deburring process of the wheel hub, the wheel hub must first be placed stably on the upper surface of the base frame 1 to ensure that the wheel hub and the base frame 1 are in close contact. Then, the clamping mechanism 3 is activated. At this time, the multiple clamping ends equipped with the clamping mechanism 3 will move in an orderly manner along the limiting groove 2. These clamping ends clamp the wheel hub from different directions at multiple points, firmly and securely fixing the wheel hub on the upper surface of the base frame 1, providing a stable foundation for subsequent processing.

[0022] Next, the user needs to precisely adjust the polishing diameter of the deburring mechanism 7 according to the actual size of the surface to be processed on the wheel hub. The specific operation is to rotate the rotating end of the deburring mechanism 7. This rotation will cause the two misaligned polishing ends to move relative to each other, and extend or retract according to the user's adjustment needs until it perfectly matches the diameter of the surface to be processed on the wheel hub.

[0023] After completing the above adjustments, the user activates the lifting mechanism 5. Driven by the lifting mechanism 5, the rotating mechanism 6 begins to move smoothly downward, thereby driving the deburring mechanism 7 to descend synchronously. When the polishing end of the deburring mechanism 7 just contacts the surface to be processed on the wheel hub, the rotating mechanism 6 is immediately activated, thereby driving the deburring mechanism 7 to rotate at high speed. Since the diameter of the polishing end of the deburring mechanism 7 is strictly consistent with the diameter of the surface to be processed on the wheel hub, during the rotation process, the polishing end can fully and evenly cover the surface to be processed on the wheel hub, achieving a complete and efficient polishing and deburring effect, restoring the surface of the wheel hub to a smooth and flat state.

[0024] like Figure 3 As shown, the deburring mechanism 7 includes a slide rail 71, a bidirectional lead screw 72, a knob 73, a slider 74, a brush bar 75, and a locking assembly 76. The lower end of the rotating mechanism 6 is fixedly connected to the slide rail 71. The bidirectional lead screw 72 is rotatably connected inside the slide rail 71. One end of the bidirectional lead screw 72 is fixedly connected to the knob 73, and the other end of the bidirectional lead screw 72 is fixedly connected to the locking assembly 76. Two sliders 74 are slidably connected inside the slide rail 71. The bidirectional lead screw 72 passes through the sliders 74 and is threadedly connected to the sliders 74. The lower ends of the two sliders 74 are fixedly connected to the brush bars 75, and the two brush bars 75 are staggered.

[0025] In this embodiment, when it is necessary to adjust the polishing diameter of the deburring mechanism 7, the user only needs to turn the knob 73. After the knob 73 is turned, it will drive the bidirectional lead screw 72 connected to it to start rotating. Under the drive of the bidirectional lead screw 72, the two sliders 74 will slide smoothly along the slide rail 71.

[0026] As the sliders 74 slide, they will cause the two brush strips 75 to move in a staggered manner. This staggered movement design allows the polishing diameter of the deburring mechanism 7 to be flexibly changed according to the diameter of the surface to be processed on the hub, whether it is increased or decreased.

[0027] Once the user adjusts the polishing diameter to a suitable size, the locking component 76 can be used to lock the adjusted deburring mechanism 7. The locking component 76 can firmly fix the positions of the two brush strips 75, ensuring that the brush strips 75 will not shift during the subsequent deburring process, thereby ensuring the quality and stability of the process.

[0028] like Figure 5 As shown, the locking assembly 76 includes a threaded block 761, a stop block 762, and a fixing block 763. The threaded block 761 is fixedly connected to the shaft end of the bidirectional lead screw 72, and the fixing block 763 is fixedly connected to one end of the threaded block 761. The stop block 762 is threadedly connected to the surface of the threaded block 761.

[0029] In this embodiment, the user holds the fixing block 763 with one hand and rotates the abutment block 762 with the other hand, so that the abutment block 762 rotates on the surface of the threaded block 761. When one end of the abutment block 762 abuts against one end of the slide rail 71, the bidirectional lead screw 72 can be locked, thereby firmly fixing the positions of the two brush strips 75.

[0030] like Figure 6 As shown, the clamping mechanism 3 includes a motor 31, a lead screw 32, a lifting block 33, a hinge plate 34, a locking block 35, and a clamping plate 36. The motor 31 is installed at the bottom of the base frame 1. The output end of the motor 31 is fixedly connected to the lead screw 32. The lifting block 33 is threadedly connected to the surface of the lead screw 32. The locking block 35 is slidably engaged inside the limiting groove 2. The clamping plate 36 is fixedly connected to the upper end of the locking block 35. Multiple hinge plates 34 are hinged to the surface of the lifting block 33. The upper end of the hinge plate 34 is hinged to the locking block 35.

[0031] In this embodiment, during the specific operation of the wheel hub clamping, the user first starts the motor 31. After the motor 31 starts, it immediately enters a stable working state, and its output power is transmitted to the lead screw 32, causing the lead screw 32 to start rotating. The rotation of the lead screw 32 is based on its specific thread design, and an axial force is generated during the rotation process.

[0032] This axial force acts on the lifting block 33, causing it to move downwards in the vertical direction. The downward movement of the lifting block 33 is a key transmission link, which is connected to multiple hinge plates 34. As the lifting block 33 moves downwards, the multiple hinge plates 34 will undergo corresponding angle changes, which will be converted into the power to drive the locking block 35 to move.

[0033] Multiple locking blocks 35 slide within the limiting groove 2 under the action of the hinge plate 34. The existence of the limiting groove 2 ensures that the sliding direction and range of the locking blocks 35 are accurate, preventing the locking blocks 35 from deviating or jamming during movement.

[0034] The sliding of the clamping block 35 is further transmitted to multiple clamping plates 36, causing the multiple clamping plates 36 to retract. This retraction motion is a multi-point external clamping action. Multiple clamping plates 36 simultaneously approach the wheel hub from different positions and apply clamping force. Since this multi-point external clamping method can be flexibly adjusted according to the actual size and shape of the wheel hub, it can effectively and firmly clamp wheel hubs of different sizes, greatly improving the clamping effect of the wheel hub and providing a solid foundation for subsequent processing procedures.

[0035] like Figure 2 As shown, the lifting mechanism 5 includes a cylinder 51, a lifting plate 52, and a limit rod 53. The cylinder 51 is installed at the upper end of the frame 4, and the lifting plate 52 is installed at the driving end of the cylinder 51. Two limit rods 53 are fixedly connected to the upper end of the lifting plate 52. The limit rods 53 pass through the holes opened on the surface of the frame 4 and are slidably connected to the frame 4.

[0036] In this embodiment, the user activates cylinder 51, which causes the lifting plate 52 to move downward, thereby causing the limiting rod 53 to slide on the surface of the frame 4. Since the limiting rod 53 plays a limiting and guiding role for the lifting plate 52, it plays a crucial limiting and guiding role throughout the entire movement. By physically constraining the movement trajectory of the lifting plate 52, the lifting plate 52 can only move in a straight line along the vertical direction during its downward movement, and will not deflect due to the influence of other external forces or uneven distribution of its own weight, thus ensuring the accuracy and stability of the mechanical system operation.

[0037] like Figure 4 As shown, the rotating mechanism 6 includes a mounting plate 61, a second motor 62, a rotating plate 63, an annular slide 64, a rotating ring 65, and a rotating rod 66. The lower end of the lifting plate 52 is fixedly connected to the mounting plate 61. The second motor 62 is mounted on the surface of the mounting plate 61. The output end of the second motor 62 is mounted to the rotating plate 63 via a connecting shaft. The lower end of the mounting plate 61 is fixedly connected to the annular slide 64. The rotating ring 65 is rotatably engaged inside the annular slide 64. The rotating ring 65 is fixedly connected to the rotating plate 63 via the rotating rod 66.

[0038] In this embodiment, when the brush strip 75 contacts the surface of the wheel hub to be processed, the user starts the motor 62, which drives the rotating plate 63 to rotate, thereby causing the brush strip 75 to rotate. The brush strip 75 polishes and deburrs the surface of the wheel hub to be processed. At the same time, due to the rotation of the rotating plate 63, the rotating rod 66 drives the rotating ring 65 to rotate inside the annular slide 64. The annular slide 64 provides precise guidance and effective limiting for the rotation of the rotating ring 65. Due to the limiting effect of the annular slide 64, the rotating ring 65 can maintain a stable motion trajectory during rotation without shaking or deviation. This stability is fed back to the rotating plate 63 through the rotating rod 66, making the rotating plate 63 more stable during rotation and reducing vibration and deviation caused by unstable rotation. This ensures that the polishing and deburring operation of the brush strip 75 on the surface of the wheel hub to be processed can be carried out evenly and continuously, improving the stability and processing accuracy of the entire device's deburring operation.

[0039] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
