As shown in fig. 2, an aluminum alloy hub grinding device 20 includes a hub rotation mechanism 30 and a hub grinding mechanism 40 engaged with the hub rotation mechanism 30.

The hub rotating mechanism 30 is used for fixing and rotating the aluminum alloy hub 10, and the hub polishing mechanism 40 is used for polishing the rotating aluminum alloy hub 10.

Specifically, as shown in fig. 3, the hub rotation mechanism 30 includes: a rotary support 100, a rotary disc 200, and a rotary drive part 300. The rotary tray 200 is rotatably disposed on the rotary support base 100, the rotary driving portion 300 is drivingly connected to the rotary tray 200, the rotary driving portion 300 drives the rotary tray 200 to rotate, and a rotation axis of the rotary tray 200 is perpendicular to a horizontal plane. In the present embodiment, the rotation driving part 300 has a motor driving structure.

Further, the hub rotating mechanism 30 further includes a hub tightening/loosening jig 400 (shown in fig. 3) disposed on the rotating disc 200. Place aluminum alloy wheel hub 10 on rotatory disk body 200, wheel hub elasticity tool 400 is used for fixing aluminum alloy wheel hub 10 on the rotatory disk body 200, prevents that aluminum alloy wheel hub 10 from taking place to shift at rotatory in-process, guarantees aluminum alloy wheel hub 10 at the stability of the in-process of polishing.

In particular, in the design and development process of the hub tightening and loosening jig 400, the following problems need to be considered: on one hand, how to fix the wheel hub quickly and stably so as to improve the production efficiency and the production stability; on the other hand, when using the tool to fix wheel hub, how shelter from wheel hub as few as possible makes things convenient for grinding machanism to polish wheel hub.

For this reason, the structure of the hub tightening jig 400 is particularly optimized, for example, as shown in fig. 4 and 5, the hub tightening jig 400 includes: an upper elastic ring 410, a lower elastic ring 420, a fixed block 430 and an elastic screw 440.

The central axis of the upper elastic ring 410 and the central axis of the lower elastic ring 420 are aligned, and the upper elastic ring 410 and the lower elastic ring 420 are spaced apart from each other to form a locking gap 401.

As shown in fig. 5, the upper elastic ring 410 has an upper fixed end 411 and an upper movable end 412, and the lower elastic ring 420 has a lower fixed end 421 and a lower movable end 422.

The fixing block 430 is fixed to the rotating disk 200, and the upper fixing end 411 of the upper elastic ring 410 and the lower fixing end 421 of the lower elastic ring 420 are fixed to the fixing block 430.

The fixing block 430 is provided with an elastic screw hole (not shown), and the elastic screw 440 is screwed in the elastic screw hole.

One end of the elastic screw is provided with a pressing plate 432, and the upper movable end 412 of the upper elastic ring 410 is connected with the lower movable end 422 of the lower elastic ring 420 and elastically pressed on the plate surface of the pressing plate 432.

The hub tightening jig 400 further includes a screw driving unit (not shown) drivingly connected to the tightening screw 440, and the screw driving unit drives the tightening screw 440 to rotate forward or backward. In this embodiment, the screw driving portion is a motor driving structure.

The following describes the operation principle of the hub tightening/loosening jig 400:

placing an aluminum alloy hub 10 to be ground on the rotary disc body 200, wherein one end face of the rim 11 is surrounded by the upper elastic ring 410 and the lower elastic ring 420, and the raised flange 12 on the edge of one end face of the rim 11 is just positioned at the locking gap 401 formed by the upper elastic ring 410 and the lower elastic ring 420;

the tightening screw 440 is driven to rotate forward by the screw driving part, because the tightening screw 440 is screwed into the tightening screw hole, and the upper movable end 412 of the upper tightening ring 410 is connected with the lower movable end 422 of the lower tightening ring 420 and elastically pressed on the plate surface of the pressing plate 432, the tightening screw 440 pushes the upper movable end 412 and the lower movable end 422 to move through the pressing plate 432, and because the upper fixed end 411 and the lower fixed end 421 are fixed on the fixed block 430, the rings of the upper tightening ring 410 and the lower tightening ring 420 are more tightened, so that the raised rim 12 on one end surface edge of the rim 11 is clamped under the combined action of the upper tightening ring 410 and the lower tightening ring 420, and the aluminum alloy hub 10 is fixed;

the tightening screw 440 is driven to rotate reversely by the screw driving part, so that the tightening screw 440 drives the pressing plate 432 to move reversely, and because the upper elastic ring 410 and the lower elastic ring 420 have elastic restoring force, in the process of the reverse movement of the pressing plate 432, the pressing plate 432 is not pressed against the upper movable end 412 and the lower movable end 422 any more, so that the ring bodies of the upper elastic ring 410 and the lower elastic ring 420 can be expanded and enlarged, the raised flange 12 on one end face edge of the rim 11 is not clamped any more, and thus, the aluminum alloy hub 10 can be taken out.

Therefore, in the process of fixing the aluminum alloy hub 10, the hub tightening and loosening jig 400 of the invention clamps the raised flange 12 on one end face edge of the rim 11 only by the upper tightening ring 410 and the lower tightening ring 420, and the raised flange 12 occupies only a small part of the whole aluminum alloy hub 10, so that the hub is shielded as little as possible, and a grinding mechanism can grind the hub conveniently. Further, the structure of the upper and lower elastic rings 410 and 420 is very simple, and it is possible to fix the aluminum alloy hub 10 only by performing simple contraction or expansion movement without designing a complicated clamping device, thus realizing quick and stable fixation of the hub, and improving production efficiency and production stability.

As shown in FIG. 5, it is also specifically noted that the upper elastic ring 410 has an upper fixed end 411 and an upper movable end 412, and the upper fixed end 411 and the upper movable end 412 are not located on the same horizontal plane (the upper movable end 412 is closer to the raised rim 12 and is movable), so that the upper elastic ring 410 applies a pressing force to the raised rim 12 toward the lower elastic ring 420 during the clamping of the raised rim 12 by the upper elastic ring 410; similarly, the lower elastic ring 420 has a lower fixed end 421 and a lower movable end 422, and the lower fixed end 421 and the lower movable end 422 are not located on the same horizontal plane (the lower movable end 422 is also closer to the raised rim 12 and is movable), so that the lower elastic ring 420 applies a pressing force to the raised rim 12 toward the upper elastic ring 410 during the process of clamping the raised rim 12 by the lower elastic ring 420; it can be seen that the raised rim 12 is not only clamped by the upper and lower tension rings 410 and 420, but also pressed by the upper and lower tension rings 410 and 420, so that the entire hub can be more stably fixed.

After the aluminum alloy hub 10 is fixed by the hub tightening jig 400, the rotary driving part 300 drives the rotary disc 200 to rotate, so that the aluminum alloy hub 10 on the rotary disc 200 and the hub tightening jig 400 also rotate, and the hub polishing mechanism 40 can polish the aluminum alloy hub 10.

In the present invention, the hub rotation mechanism 30 further includes a horizontal transfer device 500 (shown in fig. 6) for driving the rotation support base 100 to reciprocate in the horizontal direction. Specifically, as shown in fig. 6, the horizontal transfer device 500 includes a horizontal transfer holder 510 and a horizontal transfer driving unit 520, the rotary holder 100 is slidably disposed on the horizontal transfer holder 510 along the horizontal direction, and the horizontal transfer driving unit 520 is drivingly connected to the rotary holder 100. In the present embodiment, the horizontal transfer driving unit 520 is a motor screw driving structure. By arranging the horizontal transfer device 500, the aluminum alloy hub 10 on the rotary table body 200 can be horizontally moved, so that the aluminum alloy hub 10 can be transferred from one station to another station.

The following describes a specific structure of the hub grinding mechanism 40 and a connection relationship between the respective components:

as shown in fig. 7, the hub grinding mechanism 40 includes: a horizontal position adjusting device 600, an angle adjusting device 700, and a polishing device 800. The horizontal position adjusting device 600 is used for driving the grinding device 800 to reciprocate along the horizontal direction, the angle adjusting device 700 is used for driving the grinding device 800 to rotate, and the rotating shaft of the grinding device 800 is parallel to the horizontal plane.

As shown in fig. 7, in detail, the horizontal position adjusting apparatus 600 includes: a horizontal position adjusting base 610 and a horizontal position adjusting driving part 620. Specifically, the angle adjusting apparatus 700 includes: the polishing device 800 is rotatably arranged on the horizontal position adjusting sliding seat 710, and the angle adjusting driving part 720 drives the polishing device 800 to rotate. The horizontal position adjustment sliding base 710 is slidably disposed on the horizontal position adjustment base 610, and the horizontal position adjustment driving part 620 drives the horizontal position adjustment sliding base 710 to reciprocate. In this embodiment, the horizontal position adjustment driving portion 620 is a motor screw driving structure, and the angle adjustment driving portion 720 is a motor belt driving structure.

Horizontal position adjusting device 600 drive grinding device 800 is along horizontal direction reciprocating motion, and simultaneously, angle adjusting device 700 drive grinding device 800 carries out the adjustment of angle, like this, alright with adjusting grinding device 800 to the most suitable position for grinding device 800 can polish processing to aluminum alloy wheel hub 10.

According to the aluminum alloy hub polishing equipment, on one hand, the hub can be fixed quickly and stably, so that the production efficiency and the production stability are improved; on the other hand, when using the tool to fix wheel hub, can shelter from wheel hub as few as possible, make things convenient for grinding machanism to polish wheel hub.
