Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-3, the utility model provides an automobile wheel hub polishing equipment, including whole frame 1, buncher 2, can fix work piece work platform 15, be used for driving work platform 15 pivoted pivot 10 and control platform 16, buncher 2 is connected with pivot 10, pivot 10 one end is connected with work platform 15, its characterized in that: the grinding device further comprises a grinding chuck A and a guide slide rail 24 positioned on one side of the grinding chuck A, wherein a lifting slide block 22 capable of sliding up and down along the guide slide rail 24 is arranged on the guide slide rail 24, and the lower end of the lifting slide block 22 is connected with one side of the grinding chuck A; one side of the lifting slide block 22 is also connected with a braking mechanism C capable of adjusting the descending speed of the lifting slide block 22.

Preferably, the lifting slide block 22 comprises a roller triple 23 capable of sliding along the guide slide rail 24 and a fixing part for fixing the roller triple 23; the braking mechanism C comprises an adjusting screw 25, a first roller 26 and a second roller 28, the first roller 26 is connected with the second roller 28 through a belt 29, and the second roller 28 is connected with a third roller 23; the boss on the adjusting screw 25 is adjacent to the first roller 26.

Preferably, the adjusting screw 25 is connected at one end to the grinding chuck a.

In this embodiment, when the device operates, place the work piece at work platform 15 top back, it is fixed with the work piece through on the work platform, grind chuck A and begin to fall to B2 from position B1 until contacting the work piece afterwards, then open buncher 2, drive work platform 15 through the rotation of buncher 2 and rotate, the work piece at this moment is because fixing on work platform 15, just do synchronous motion with work platform 15, the work piece does regular positive and negative rotary motion for grinding chuck A, can reach the grinding effect to the work piece like this, the burr outstanding in work piece surface and periphery is ground off, and sharp-edged rounding and surface finish are handled.

The function of the elevator slide 22 is to effect longitudinal movement of the lapping chuck a. In this embodiment, the lifting slide block 22 is designed as a pulley, and includes a roller triple 23 capable of sliding along the guide slide rail 24 and a fixing member for fixing the roller triple 23, the roller triple 23 is fixed on the fixing member and slidably connected with the guide slide rail 24 through the fixing member, and the lower end of the fixing member is connected with the right side of the grinding chuck a. When the three rollers 23 slide up and down along the guide slide rail 24, the grinding chuck A can be driven to synchronously move.

Because the workpiece is driven by the working platform 15 to rotate, the grinding chuck a contacting with one side of the workpiece needs to well grind, and a certain pressure needs to be applied towards the direction of the workpiece, so that the workpiece and the grinding chuck can be well, fully and uniformly contacted in motion, and the grinding effect is realized. Meanwhile, because one end of the grinding chuck A is connected with the lifting slide block 22, if a downward acting force is lacked, the roller three 23 is easily carried to slide upwards along the guide slide rail 24 reversely during the operation of the workpiece. The brake mechanism C is arranged on one side of the lifting slide block 23, namely, the grinding chuck A can be controlled to slide reversely, and meanwhile, the descending speed of the grinding chuck A can be adjusted to realize the bonding force between the grinding chuck A and a workpiece in the grinding process, so that the polishing quality is improved.
