Description

Technical Field

[0001] The utility model relates to the technical field of polishing equipment, in particular to a polishing device for processing aluminum alloy wheel hubs. Background Art

[0002] Aluminum alloy wheels generally use low-pressure casting processing technology, but the original surface roughness of the wheels produced by die-casting is large. Before the wheel is electroplated, it needs to be ground and polished to reduce the roughness of the wheel surface.

[0003] Announcement No. CN219704607U discloses a polishing device for processing automobile aluminum alloy wheel hubs. The device installs the wheel hub on the lifting clamp at the end of the transmission shaft and locks it, starts the first motor, and the first motor drives the transmission shaft to rotate, thereby driving the wheel hub to rotate. The polishing cylinder is fixed. Since the wheel hub rotates with the motor and reciprocates up and down through the lifting bracket, a cyclone-type rolling grinding is generated between the abrasive in the polishing cylinder and the wheel hub. The abrasive block in a free state automatically fits the free curved surface of the wheel hub to produce relative movement. When the abrasive particles on the surface of the abrasive block repeatedly slide and scratch the surface metal of the wheel hub, the surface metal undergoes multiple superpositions of plastic deformation. When the degree of plastic deformation exceeds the limit allowed by the material, micro-chips fall off from the metal body, thereby achieving micro-grinding of the wheel hub surface, thereby achieving the purpose of evenly removing burrs, chamfering and polishing on the wheel hub. However, the patent still has the following problems in actual use:

[0004] The device starts the first motor, and as the wheel hub rotates with the motor and reciprocates up and down through the lifting bracket, cyclone-type rolling grinding is generated between the abrasive in the polishing cylinder and the wheel hub, thereby achieving micro-grinding of the wheel hub surface, thereby achieving the purpose of evenly removing burrs, chamfering and polishing on the wheel hub. However, when the device polishes the wheel hub, it is necessary to simultaneously start the first motor and the two sets of electric push rods on the lifting bracket to achieve the effect of rotating and polishing the wheel hub up and down, which greatly increases the use cost of the device, fails to achieve energy-saving effects, and does not meet the use needs of small workshops.

[0005] A polishing device for aluminum alloy wheel hub processing is proposed to solve the above problems. Utility Model Content
