Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub positioning, in particular to a positioning tool for wheel hub drilling. Background Art

[0002] In the wheel hub manufacturing industry, drilling is one of the important processing steps, which directly affects the quality and performance of the wheel hub. However, due to the different shapes and sizes of the wheel hub, the traditional drilling method often has problems such as inaccurate positioning and unstable clamping, which not only affects the drilling accuracy, but also may cause damage to the wheel hub and even lead to the failure of the entire processing process.

[0003] In order to solve these problems, some positioning tools for wheel hub drilling have appeared on the market in recent years, but they still have shortcomings in adapting to different sizes of wheels, ensuring clamping stability and providing buffer protection. For example, some tools can only adapt to wheels of specific sizes and cannot adapt to diversified production needs; although other tools can achieve clamping, the clamping force is uneven and it is easy to cause damage to the wheel hub; and some tools lack buffer protection mechanisms and cannot effectively avoid the impact on the wheel hub during the clamping process.

[0004] In view of this, the existing structure and defects are studied and improved, and a positioning tool for wheel hub drilling is provided, in order to achieve a more practical purpose. Utility Model Content

[0010] Preferably, the fixing block is configured as a T-shaped body, and sliding grooves are respectively provided on both sides of the upper end of the fixing block.

[0011] Preferably, a movable plate is provided in the center of the upper end of the fixed block, and vertical poles are fixedly connected to both ends of the movable plate, wherein a driving rod is fixedly connected to the center of the movable plate, and the lower end of the driving rod extends to the lower end of the base and is fixedly installed on the front end of the rotating motor.

[0013] Preferably, the movable component is arranged into two groups, and each group comprises a slider, a support block, a clamping block and a rubber gasket. The two sliders are movably arranged on the upper end surface of the fixed block, and the support block is fixedly installed on the upper end of the slider, and the clamping block is fixedly connected to the upper end of the support block, and rubber gaskets are arranged on the inner side of the clamping block.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a positioning tool for wheel hub drilling, which has the following beneficial effects:

[0018] 1. By rotating the screw to adjust the height of the limit ring, it can adapt to wheels of different sizes and achieve wide applicability. The rotating motor drives the slider to move along the slide groove, which in turn drives the clamping block and the rubber gasket to move closer to the center of the mounting seat to achieve stable clamping of the wheel hub, which not only ensures the clamping accuracy, but also improves the clamping efficiency. The elastic deformation of the rubber gasket can fit closely to the surface of the wheel hub, effectively preventing the wheel hub from shaking during processing, and ensuring processing accuracy and stability.

[0019] 2. During the clamping process, the buffer assembly composed of the cross bar and the limit spring can provide buffering for the clamping process, avoiding sudden impact on the wheel hub, thereby protecting the surface of the wheel hub from damage. The compression of the limit spring not only provides a buffering effect, but also ensures the uniform distribution of the clamping force, avoiding deformation or damage of the wheel hub caused by uneven clamping force. The limit ring limits the compression of the limit spring, effectively preventing the spring from being over-compressed and losing the buffering effect, thereby ensuring the stability and reliability of the entire clamping process.

[0027] The moving component is fixedly sleeved on the outer end of the fixed block 4 and is used for stably clamping inside the mounting seat 5 .

[0028] Furthermore, the fixing block 4 is configured as a T-shaped body, and sliding grooves 6 are respectively provided on both sides of the upper end of the fixing block 4 .

[0029] Furthermore, a movable plate 10 is provided at the center of the upper end of the fixed block 4, and vertical rods 11 are fixedly connected to both ends of the movable plate 10, wherein a driving rod 12 is fixedly connected to the center of the movable plate 10, and the lower end of the driving rod 12 extends to the lower end of the base 1 and is fixedly installed at the front end of the rotating motor 3.

[0030] Furthermore, the mounting seat 5 includes a limiting ring 7, a fixing rod 8 and a screw 9, wherein the fixing rods 8 are fixedly installed on both sides of the lower end of the limiting ring 7, and the bottom ends of the fixing rods 8 are fixedly connected to the surface of the fixing block 4, wherein the upper end surface of the limiting ring 7 is provided with a screw 9, and the screw 9 is used to tightly fix the limiting ring 7 and the fixing rod 8.

[0031] Furthermore, the moving components are configured as two groups, and each group includes a slider 13, a support block 14, a clamping block 15 and a rubber gasket 16. The two sliders 13 are movably arranged on the upper end surface of the fixed block 4, and the support blocks 14 are fixedly installed on the upper ends of the sliders 13, and the clamping blocks 15 are fixedly connected to the upper ends of the support blocks 14, and rubber gaskets 16 are arranged on the inner sides of the clamping blocks 15.

[0032] Furthermore, the two sliders 13 are arranged opposite to each other, and a buffer assembly is provided on the opposite side of the support block 14, wherein a screw rod 17 is fixedly provided on one side of the front end of the two sliders 13, and a transmission plate 18 is fixedly connected to the outer end of the screw rod 17, and the other end of the transmission plate 18 is fixedly connected to the outer end of the vertical rod 11.

[0033] Furthermore, the buffer assembly includes a cross bar 19, a limit spring 20 and a limit ring 21. The two ends of the cross bar 19 are respectively inserted into the interior of the support blocks 14 at both ends, and the limit springs 20 are respectively sleeved on both sides of the outer ends of the cross bar 19, and the end of the limit spring 20 is fixedly connected to the front side of the support block 14, and the limit ring 21 is fixedly connected to the front end of the limit spring 20.

[0034] Working principle: when the wheel hub needs to be placed on the mounting seat 5, first adjust the height of the limit ring 7 by rotating the screw rod 9 to adapt to the wheel hubs of different sizes, then start the rotating motor 3, the motor drives the driving rod 12 to rotate, and drives the screw rod 17 to move through the vertical rod 11 and the transmission plate 18. The movement of the screw rod 17 causes the slider 13 to move toward each other in the horizontal direction in the slide groove 6 of the fixed block 4, thereby driving the support block 14, the clamping block 15 and the rubber gasket 16 to move closer to the center of the mounting seat 5. When the rubber gasket 16 on the inner side of the clamping block 15 contacts the surface of the wheel hub, continuing to move the slider 13 will cause the rubber gasket 16 to produce elastic deformation, thereby tightly It fits the surface of the wheel hub to achieve stable clamping. During the clamping process, when the clamping block 15 contacts the wheel hub and moves, the cross bar 19 between the support blocks 14 will be subjected to pressure, thereby compressing the limit springs 20 on both sides. The compression of the limit springs 20 not only provides a buffer for the clamping process and avoids sudden impact on the wheel hub, but also ensures the uniform distribution of the clamping force. The limit ring 21 is used to limit the compression amount of the limit spring 20 to prevent it from being over-compressed and losing the buffering effect. After the processing is completed, the screw 9 is rotated in the opposite direction to loosen the limit ring 1 7, and then the rotary motor 3 is rotated in the opposite direction to make the clamping block 15 loosen the wheel hub, thereby conveniently removing the wheel hub from the mounting seat 5.
