Description

Technical Field

[0001] This utility model relates to the technical field of wheel hub processing equipment, specifically to a wheel hub surface wire drawing device. Background Technology

[0002] Wheel hubs are crucial vehicle components, consisting of the rotating part of the wheel core connected to the inner rim of the tire via a pillar, primarily manufactured through casting. Due to market demand, some wheel hubs require a brushed finish. Brushing is a technique that uses mechanical motion to create a uniform, macroscopic texture on the metal surface. This treatment imparts a non-mirror-like metallic luster, providing a strong decorative effect. Currently, brushed finishes on wheel hubs are mainly performed using CNC lathes. However, CNC lathes are expensive and not suitable for producing small batches of individual wheel hubs.

[0003] Therefore, how to design a device suitable for wire drawing processing of small batches of scattered wheel hub products has become an urgent technical problem to be solved in this field. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies and provide a wheel hub surface drawing device suitable for small-batch, scattered wheel hub products.

[0005] The technical solution adopted by this utility model is: a wheel hub surface wire drawing device, comprising a frame, a main shaft mounted on the frame, and a rotary drive assembly for driving the main shaft to rotate; wherein...

[0007] The rotary drive assembly includes a transmission belt and a rotary drive source. The rotary drive source drives the spindle to rotate via the transmission belt, thereby driving the clamping fixture to rotate.

[0008] Preferably, the clamping bar is provided with a plurality of limiting blocks for preventing the wheel hub from shaking, and the limiting blocks on the same clamping bar are distributed in a stepped manner.

[0009] Preferably, the limiting block is detachably mounted on the clamping bar.

[0018] This utility model has the following advantages compared with the prior art:

[0019] 1. This utility model relates to a wheel hub surface wire drawing device. A clamping fixture clamps the wheel hub, and a rotary drive source drives the main shaft to rotate via a transmission belt. The main shaft then drives the clamping fixture to rotate, thus rotating the wheel hub. At this point, manual laborers press special sandpaper onto the wheel spoke surface and drag it at a uniform speed from the center outwards to perform the wire drawing process. This design is ideal for small-batch wire drawing of wheel hubs, offering high production efficiency, strong wire drawing texture, and significantly reducing equipment costs for enterprises.

[0020] 2. The wheel hub surface wire drawing equipment of this utility model has a stepped distribution of limiting blocks on the clamping bar of the clamping fixture. The spacing of the limiting blocks is designed according to several commonly used wheel hub products. In addition, the clamping bar and the base are detachably slidably connected. The clamping fixture can be detachably installed on the main shaft. When the size of the wheel hub exceeds the original clamping bar, a clamping bar of the corresponding size can be replaced, or the entire clamping fixture can be replaced. The operation is flexible and the application range is wide, further reducing the equipment cost of enterprises. Attached Figure Description

[0027] To enhance understanding of this utility model, it will be further described in detail below with reference to embodiments and accompanying drawings. This utility model can be implemented in the following ways:

[0028] Reference Figure 1-4 A wheel hub surface wire drawing device includes a frame 1, a main shaft 2 mounted on the frame 1, and a rotary drive assembly 3 for driving the main shaft 2 to rotate.

[0029] To secure the wheel hub, the top of the main shaft 2 is detachably equipped with a clamping fixture 4 for clamping the wheel hub. The clamping fixture 4 includes a base 41, several clamping bars 42 slidably connected to the base 41 and distributed circumferentially, and a clamping drive source (not shown in the figure) that controls the radial reciprocating motion of the clamping bars 42. The clamping drive source controls all the clamping bars 42 to converge or disperse towards the center of the base 41, thereby clamping or releasing the wheel hub.

[0030] Specifically, the clamping bar 42 is provided with several limiting blocks 421 to prevent the wheel hub from shaking. The limiting blocks 421 on the same clamping bar 42 are distributed in a stepped manner, and each limiting block 421 corresponds to a different type of wheel hub. In this embodiment, the clamping bar 42 is provided with three limiting blocks 421, which is applicable to the wire drawing process of three sizes of wheel hubs. The limiting blocks 421 are detachably installed on the clamping bar 42. The clamping bar 42 and the base 41 are detachably slidably connected. When the size of the wheel hub exceeds the original clamping bar 42, a clamping bar 42 of the corresponding size can be replaced, or the entire clamping fixture 4 can be replaced, which is flexible in operation and has a wide range of applications.

[0031] To allow the clamping bars 42 to converge or disperse, the base 41 has a guide rail 411 at the corresponding position of the clamping bars 42. The clamping bars 42 are slidably connected to the guide rail 411 via a slider 43 at its bottom. The clamping bars 42 and the slider 43 are detachably connected. The clamping bars 42 are detachably connected to the slider 43 via bolts. The clamping bars 42 have fixing holes 422 for bolts to pass through. The guide rail 411 is a U-shaped guide rail, with protrusions 4111 on both inner sides to hold the sides of the slider 43. The slider 43 has grooves 431 on both sides that correspond to the protrusions 4111. The design of the protrusions 4111 and the grooves 431 serves as a guide, preventing the clamping bars 42 from shifting during movement and affecting the processing quality. The clamping drive source is a cylinder, and the slider 43 is connected to the cylinder. The clamping drive source controls the slider 43 to move back and forth along the guide rail 411, thereby causing all the clamping bars 42 to converge or disperse toward the center of the base 41.

[0032] To drive the spindle 2 to rotate, the rotary drive assembly 3 includes a transmission belt 31 and a rotary drive source 32. The top of the spindle 2 is provided with a mounting base 21 for mounting the clamping fixture 4, and the bottom of the spindle 2 is provided with a gear 22 connected to the transmission belt 31. The rotary drive source 32 is a motor. The rotary drive source 32 drives the spindle 2 to rotate via the transmission belt 31, thereby driving the clamping fixture 4 to rotate.

[0033] Operating Method: Select the appropriate clamping bar 42 according to the required wheel hub size. Place the wheel hub on the clamping fixture 4, and use the clamping drive source to drive the slider 43 to move the clamping bar 42 towards the center of the base 41, thereby clamping the wheel hub. Next, use the rotary drive source 32 to drive the spindle 2 to rotate via the transmission belt 31. The spindle 2 drives the clamping fixture 4 to rotate, thus rotating the wheel hub. When the wheel hub reaches the required speed, manually press special sandpaper onto the spoke surface and drag it uniformly from the center outwards to perform the wire drawing process. After the wire drawing is completed, stop the rotary drive source 32 (motor). After the wheel hub comes to rest, the clamping bar 42 of the clamping fixture 4 resets, releasing the wheel hub, which can then be removed. The operation is simple and quick, making it very suitable for small-batch wire drawing of wheel hubs, with high production efficiency and a strong wire drawing texture.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
