Description

Technical Field

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

[0002] In the production and processing of motorcycle wheel hubs, grinding is a key step in improving the surface quality of the wheel hub. It can effectively reduce the surface roughness of the wheel hub, remove defects such as burrs, and lay a good foundation for subsequent fine polishing operations.

[0003] However, current motorcycle wheel polishing operations face numerous challenges. Due to the diverse and often complex shapes of motorcycle wheels, traditional manual polishing methods are extremely cumbersome, requiring highly skilled operators and exhibiting low efficiency, making it difficult to meet the demands of mass production. Furthermore, wheel positioning is a significant issue during polishing. While some existing polishing devices use fixed fixtures for wheel positioning, these fixtures often struggle to accommodate the positioning requirements of wheels with different shapes, and are inconvenient to install and remove, further impacting production efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a grinding device for motorcycle wheel hub production and processing, which solves some of the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a grinding device for manufacturing and processing motorcycle wheel hubs, comprising a processing table, a rotating shaft, and a support plate. A sand tank is provided in the middle of the processing table. Insert blocks are symmetrically installed at the lower end of the support plate, and insert rods penetrate through the interior of the insert blocks. An insertion hole is provided on the rotating shaft near its lower end, and the insert rods penetrate through the insertion holes. Evenly distributed fixing rods are fixedly installed on the upper end of the support plate. Support springs are installed on the outer side of the fixing rods on the upper end of the support plate. Rubber washers are slidably sleeved on the outer side of the fixing rods above the support springs. A fixing plate is fixedly sleeved on the rotating shaft near its lower side. Evenly distributed through holes are provided on the fixing plate, and the fixing rods and through holes correspond one-to-one and are compatible.

[0006] Furthermore, each of the insert blocks has a fastener threaded through and connected to one end, and the inner end of the fastener is pressed against the insert rod to prevent the insert rod from falling off under external force.

[0007] Furthermore, guide rails are fixedly installed on the upper end of the processing table near the left and right sides. Slide blocks are slidably installed inside the guide rails. Electric push rods are fixedly installed at the middle of the upper end of the slide blocks. Through the design of the guide rails and slide blocks, it is convenient to move the device to a suitable position when disassembling and assembling wheel hubs, so as to avoid obstructing the operation.

[0008] Furthermore, a frame plate is fixedly installed between the upper ends of the electric push rod, and a geared motor is fixedly installed at the middle of the upper end of the frame plate. The output end of the geared motor is fixedly connected to the rotating shaft through a coupling. The structure is simple and reduces the cost of use.

[0009] Furthermore, each guide rail has a detachable insert plate that runs through the sliding block. Each upper end of the sliding block has a reinforcing rod fixedly installed on both the front and rear sides of the electric push rod. The reinforcing rods run through and slide within the frame plate. The insert plate design ensures that the hub can be positioned in the middle of the sand pit during grinding. The reinforcing rods can reduce the load on the electric push rod and improve the structural strength and stability of the frame plate.

[0010] The advantages of this utility model are as follows:

[0011] 1. In terms of wheel hub positioning, this grinding device uses a fixing rod that passes through the wheel hub adapter bolt hole. The rotating shaft descends and, together with the insert rod and insert block, achieves a stable connection with the support plate. At the same time, the fixing plate is fitted onto the fixing rod through the through hole, forming multiple positioning guarantees. This eliminates the need for traditional and complex fixed tooling, making disassembly, assembly, and positioning operations convenient and quick. Through the cooperation of the support spring and rubber washer, the wheel hub surface can be better prevented from being obstructed, thus avoiding affecting the overall grinding effect and ensuring the integrity of this solution.

[0012] 2. This device slowly places the wheel hub into the sand tank. During rotation, the ceramic particles continuously generate relative sliding friction with the wheel hub surface, enabling all-round grinding of the outer surface of the wheel hub. Compared with traditional manual grinding methods, this device can achieve continuous and stable grinding operations, reduce the uncertainty caused by manual operation, and improve grinding efficiency. At the same time, during the rotation of the wheel hub, the ceramic particles can fully contact all parts of the wheel hub, including some complex curved surfaces that are difficult to reach manually, making the grinding effect more uniform and comprehensive, achieving a preliminary polishing effect, which is beneficial to reducing the need for subsequent fine polishing operations.

[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] Please see Figures 1-3A grinding device for manufacturing motorcycle wheel hubs includes a processing table 1, a rotating shaft 2, and a support plate 3. A sand pit 20 is provided in the middle of the processing table 1. Insert blocks 4 are symmetrically installed at the lower end of the support plate 3, with insert rods 5 passing through the interior of each insert block 4. Insert holes 6 are provided on the rotating shaft 2 near its lower end, with the insert rods 5 passing through the insertion holes 6. Evenly distributed fixing rods 8 are fixedly installed on the upper end of the support plate 3. Support springs 9 are installed on the outer sides of the fixing rods 8 on the upper end of the support plate 3. Rubber washers 10 are slidably fitted onto the upper end of the support spring 9. A fixed plate 11 is fixedly fitted onto the rotating shaft 2 near the lower side. The fixed plate 11 has evenly distributed through holes 12. The fixed rod 8 corresponds to and fits the through holes 12 one by one. One end of each insert block 4 is threaded with a fastener 7. The inner end of the fastener 7 is pressed against the insert rod 5. First, place the hub on the support plate 3 and make the fixed rod 8 pass through the bolt hole on the matching hub. The electric push rod 15 can be opened to extend or retract the hub. The device drives the shaft 2 and other structures to rise and fall. The shaft 2 descends and passes through the center hole of the hub and the support plate 3. Then, the insertion rod 5 passes through the insertion block 4 and the insertion hole 6 in sequence. The insertion rod 5 is secured by tightening the fastener 7 to prevent it from falling off. Simultaneously, the fixing plate 11 on the shaft 2 descends. Through the design of the through hole 12, it can be aligned and fitted onto the fixing rod 8. This completes the connection and fixation between the support plate 3, the shaft 2, and the hub. When the electric push rod 15 is opened again to raise and lower the shaft 2, the limiting support of the insertion rod 5 drives the support plate 3 and the hub to rise and fall, allowing the fixed hub to be slowly placed into the sand tank 20. Compared to traditional manual methods, this device has higher grinding efficiency and is suitable for mass production. Furthermore, it is convenient and quick to disassemble and position the hub, eliminating the need for fixed fixtures. The cooperation of the support spring 9 and the rubber washer 10 better prevents the hub surface from being obstructed, thus ensuring the integrity of the solution.

[0019] Please see Figure 1The upper end of the processing table 1 is fixedly equipped with guide rails 13 near the left and right sides. Slide seats 14 are slidably installed inside the guide rails 13. Electric push rods 15 are fixedly installed at the middle of the upper end of each slide seat 14. A frame plate 16 is fixedly installed between the upper ends of the electric push rods 15. A geared motor 17 is fixedly installed at the middle of the upper end of the frame plate 16. The output end of the geared motor 17 is fixedly connected to the rotating shaft 2 via a coupling. Removable insert plates 18 penetrate the guide rails 13 where they mate with the slide seats 14. Reinforcing rods 19 are fixedly installed on the upper end of the slide seats 14 at both the front and rear sides of the electric push rods 15. The reinforcing rods 19 penetrate... The wheel hub is slidably connected inside the frame plate 16. By turning on the geared motor 17, its output end can drive the rotating shaft 2 to rotate. When the rotating shaft 2 rotates, the limiting action of the insert rod 5 and the fixed plate 11 can drive the support plate 3 and the fixed rod 8 to rotate, thereby driving the wheel hub to rotate synchronously. Finally, it can sink into the ceramic particles in the sand pool 20. Then, driven by the geared motor 17, it continues to rotate, causing the ceramic particles to generate relative sliding friction with the surface of the wheel hub, realizing the comprehensive grinding of the outer surface, reducing the roughness and burrs of the wheel hub, and achieving a preliminary polishing effect, which is beneficial to reducing the need for subsequent fine polishing.

[0020] Working principle: In use, first place the wheel hub on the support plate 3, and let the fixing rod 8 pass through the bolt hole on the matching wheel hub. By opening the electric push rod 15, its telescopic end can drive the shaft 2 and other structures to rise and fall. By lowering the shaft 2 and passing it through the center hole of the wheel hub and the support plate 3, the insertion rod 5 is used to pass through the insertion block 4 and the insertion hole 6 in sequence. The fastener 7 is tightened to hold the insertion rod 5 in place to prevent it from falling off. At the same time, the fixing plate 11 on the shaft 2 falls synchronously. Through the design of the through hole 12, it can be fitted onto the fixing rod 8 after alignment. At this time, the connection and fixation between the support plate 3, the shaft 2, and the wheel hub are completed. When the electric push rod 15 is opened again to raise and lower the shaft 2, the limiting support of the insertion rod 5 can... The support plate 3 and the wheel hub are raised and lowered, allowing the wheel hub, which is fixed in place, to be slowly placed into the sand tank 20. At the same time, by turning on the reduction motor 17, its output end can drive the rotating shaft 2 to rotate. When the rotating shaft 2 rotates, the limiting action of the insertion rod 5 and the fixed plate 11 can drive the support plate 3 and the fixed rod 8 to rotate, thereby driving the wheel hub to rotate synchronously. Finally, it can sink into the ceramic particles in the sand tank 20. Then, driven by the reduction motor 17, it continues to rotate, causing the ceramic particles to generate relative sliding friction with the surface of the wheel hub, realizing the comprehensive grinding of the outer surface, reducing the roughness and burrs of the wheel hub, and achieving a preliminary polishing effect, which is beneficial to reducing the need for subsequent fine polishing.
