Description

Technical Field

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

[0002] The wheel hub is a core component of a vehicle's wheel, located at its center. It connects the axle and tire, supports the wheel's weight, and ensures smooth rotation. Wheel hubs play a crucial role in a vehicle's driving performance, handling stability, and aesthetic design. During wheel hub processing or maintenance, centering and clamping of the wheel hub is necessary, typically performed manually using adjustable clamps.

[0003] In the existing technology, the process of manually adjusting the clamp to hold the wheel hub requires constant and repeated adjustments to the position of the wheel hub and the clamp. This is not only complicated to operate, but also easily leads to the center of the wheel hub not being aligned with the center of the processing equipment after being clamped, which will affect the maintenance and processing of the wheel hub. Utility Model Content

[0004] In view of this, the present invention provides a clamping device for automatic centering of wheel hubs. The main technical problem to be solved is: to automatically perform centering clamping work on wheel hubs, to ensure that the center of the wheel hub is aligned with the center of the processing equipment, and to stably clamp the wheel hub.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a clamping device for automatic hub centering, comprising a clamping platform, wherein an installation hole is provided inside the clamping platform, a centering assembly is installed inside the clamping platform, the centering assembly includes a central shaft, the central shaft is movably connected inside the clamping platform, a sliding groove is provided inside the central shaft, four sliding grooves are provided, a spring is provided inside the sliding groove, one end of the spring is fixedly connected inside the sliding groove, and the other end of the spring is fixedly connected to a clamping plate, a limit shaft is fixedly connected to the outer wall of the clamping plate, and the limit shaft is slidably connected inside the sliding groove.

[0006] By adopting the above technical solution, the four slides are set into two symmetrical groups, and four springs support the four clamping plates respectively. The elasticity of the springs causes the clamping plates to move outward, thereby supporting the wheel hub body and achieving the effect of centering the wheel hub body.

[0007] As a further description of the above technical solution: an electric telescopic rod is fixedly connected to the lower surface of the clamping platform, the output end of the electric telescopic rod is fixedly connected to the lower end of the central shaft, a hub body is provided inside the clamping platform, a central hole is opened inside the hub body, and the clamping plate is movably connected inside the central hole.

[0008] By adopting the above technical solution, the hub body is driven to align the center hole with the center shaft and snap it in for centering work. The electric telescopic rod can then drive the center shaft to extend and retract. After the centering and clamping work is completed, the center shaft can be adjusted to be placed inside the center hole according to actual usage requirements.

[0009] As a further description of the above technical solution: the clamping platform has a limiting groove inside, and there are four sets of limiting grooves. A clamping block one is slidably connected inside the limiting groove, and a clamping block two is slidably connected inside the limiting groove. A fixing frame one is fixedly connected to the lower surface of the clamping block one.

[0010] By adopting the above technical solution, the positions of clamping block one and clamping block two are symmetrical, and both clamping block one and clamping block two are limited to sliding inside the slide groove.

[0011] As a further description of the above technical solution: a cylinder is fixedly connected to the outer wall of the first fixing frame, and two cylinders are provided. The two cylinders are located on both sides of the outer wall of the first fixing frame, and the output ends of the two cylinders are fixedly connected to a second fixing frame. The second fixing frame is fixedly connected to the lower surface of the second clamping block.

[0012] By adopting the above technical solution, two cylinders are used to connect the first fixed frame and the second fixed frame, thereby enabling the cylinders to drive the first clamping block and the second clamping block to slide synchronously.

[0013] As a further description of the above technical solution: the outer wall of the clamping block one is rotatably connected to the connecting rod one, the outer wall of the clamping block two is rotatably connected to the connecting rod two, the outer wall of the connecting rod one is rotatably connected to the rotating plate, the connecting rod two is rotatably connected to the outer wall of the rotating plate, and the rotating plate is rotatably connected to the outer wall of the electric telescopic rod.

[0014] By adopting the above technical solution, while clamping block one and clamping block two slide, they drive connecting rod one and connecting rod two to rotate and drive the rotating plate to rotate. The rotating plate is limited to rotating on the outer wall of the electric telescopic rod.

[0015] As a further description of the above technical solution: the outer wall of the rotating plate is rotatably connected to a connecting rod three, and there are two connecting rod three. The outer wall of the connecting rod three is rotatably connected to a clamping block three, and the clamping block three is slidably connected inside the limiting groove.

[0016] By adopting the above technical solution, the rotating plate drives the two connecting rods to rotate by three angles, thereby causing the two clamping blocks to slide in the limiting grooves in three limiting positions.

[0017] By employing the above technical solution, the clamping device for automatic hub centering of this utility model has at least the following beneficial effects:

[0018] Compared with the prior art, this automatic wheel hub centering clamping device, by pressing four clamping plates, causes the clamping plates to slide inside the limiting axial slide groove and compress the spring, aligning the center hole inside the wheel hub body with the center axis and placing it through the clamping plates. When the clamping plates are released, the spring causes the clamping plates to reset and expand outward, so that the clamping plates are supported on the inner wall of the center hole, thereby positioning the center of the wheel hub body and assisting in centering clamping.

[0019] Compared with the prior art, this automatic wheel hub centering clamping device activates two cylinders, which extend and retract to drive the first and second fixed frames to slide synchronously and center. While the first and second fixed frames slide, they also drive the first and second connecting rods to rotate and rotate the rotating plate. The sliding of the first and second fixed frames also drives the first and second clamping blocks to slide, and simultaneously drives the two third connecting rods to rotate, causing the two third clamping blocks to slide in the center. This achieves the effect of clamping the first and second clamping blocks and the two third clamping blocks to clamp the outer wall of the wheel hub body, thus achieving the effect of automatic clamping of the wheel hub body.

The clamping platform 1 is provided with the wheel hub body 3. The wheel hub body 3 has a central hole 301. The clamping plate 204 is movably connected to the inside of the central hole 301.

[0029] The clamping platform 1 has four sets of limiting grooves 4, which are symmetrically designed. A first clamping block 5 and a second clamping block 6 are slidably connected inside the limiting grooves 4. The first clamping block 5 and the second clamping block 6 slide within the limiting grooves 4. A fixing frame 7 is fixedly connected to the lower surface of the first clamping block 5. Two cylinders 8 are fixedly connected to the outer wall of the fixing frame 7, located on either side of the outer wall of the fixing frame 7. A second fixing frame 9 is fixedly connected to the output end of the two cylinders 8, and is fixedly connected to the lower surface of the second clamping block 6. The cylinders 8 are used to drive the second clamping block 6. Fixed frame 1 7 and fixed frame 2 9 slide in alignment to achieve synchronous sliding of clamping block 1 5 and clamping block 2 6. The outer wall of clamping block 1 5 is rotatably connected to connecting rod 1 11, the outer wall of clamping block 2 6 is rotatably connected to connecting rod 2 12, the outer wall of connecting rod 1 11 is rotatably connected to rotating plate 10, connecting rod 2 12 is rotatably connected to the outer wall of rotating plate 10, rotating plate 10 is rotatably connected to the outer wall of electric telescopic rod 206, the outer wall of rotating plate 10 is rotatably connected to connecting rod 3 14, there are two connecting rods 3 14, the two connecting rods 3 14 are symmetrically designed, the outer wall of connecting rod 3 14 is rotatably connected to clamping block 3 13, clamping block 3 13 is slidably connected inside the limiting groove 4.

[0030] Working principle: In use, firstly, the clamping table 1 is fixedly installed inside the processing equipment through the mounting hole 15. The electric telescopic rod 206 and cylinder 8 are connected to the remote control device. First, the electric telescopic rod 206 is activated to raise the central shaft 201, causing the central shaft 201 to raise the four clamping plates 204 to a certain height. At this time, pressing the four clamping plates 204 causes them to slide the limiting shaft 205 into the sliding groove 202. Then, the center hole 301 inside the wheel hub body 3 is aligned with the position of the central shaft 201. During placement, the center hole 301 slides against the outer wall of the clamping plate 204. At this time, the clamping plate 204 can be released, and the spring 203 drives the clamping plate 204 to reset, causing it to move outward and lock into the inner wall of the center hole 301, achieving the effect of centering the wheel hub body 3. This assists in the subsequent automatic clamping of the wheel hub body 3. Once the wheel hub body 3 is placed... Figure 1 As shown, two cylinders 8 are activated, which drive the first fixed bracket 7 and the second fixed bracket 9 to slide synchronously in the center. Simultaneously, the sliding of the first fixed bracket 7 and the second fixed bracket 9 causes the first clamping block 5 and the second clamping block 6 to slide and clamp onto the outer wall of the wheel hub body 3. At the same time, it causes the first connecting rod 11 and the second connecting rod 12 to rotate, and also causes the rotating plate 10 to rotate. During the rotation of the rotating plate 10, the two third connecting rods 14 to rotate, which in turn causes the two third clamping blocks 13 to slide within the limiting groove 4 and clamp onto the outer wall of the wheel hub body 3. By using the first clamping block 5, the second clamping block 6, and the two third clamping blocks 13 to simultaneously clamp onto the outer wall of the wheel hub body 3, the wheel hub... The main body 3 is firmly clamped, and with the support of the clamping plate 204 for the center hole 301, the center of the wheel hub body 3 is aligned with the center of the processing equipment while being clamped, achieving the effect of automatic centering clamping. At the same time, the support of the clamping plate 204 for the inner wall of the center hole 301 also prevents the wheel hub body 3 from shaking during processing. After the clamping is stable, when it is not necessary to use the clamping plate 204 to support the inner wall of the center hole 301, the electric telescopic rod 206 can be activated to drive the central shaft 201 to move down, so that the clamping plate 204 can slide out of the interior of the center hole 301. The position of the clamping plate 204 can be adjusted according to the actual processing requirements.
