The present invention relates to a device for removal of wheel rim burr which removes burrs on an edge of a spoke hole of a wheel rim automatically.
A conventional method for manufacturing a wheel rim made of aluminum alloy comprises the steps of pull-extruding an aluminum alloy material into an aluminum alloy long bar, rounding the aluminum alloy long bar into an aluminum alloy ring by a rolling machine, is connecting two ends of the aluminum alloy ring to obtain a wheel rim, drilling plural spoke holes at an internal side of the wheel rim for passing through and assembling with plural spoke wires.
Burrs are generated at edges of the spoke holes after drilling. In order to reduce difficulties of assembling the spoke wires, the burrs at the edges of the spoke holes must be removed. In the conventional method, burrs on the edges of the spoke holes are removed by a worker holds a sandpaper or other tools to grind the burrs. However, the conventional method requires a lot of manpower and is time-consuming to remove burrs on the spoke holes by manpower, so it has increased production cost. In addition, workers removing burrs on the spoke holes may be accidently injured by the sandpaper, the tools or the burrs on the spoke holes. If the workers are careless in operation, it may also cause incomplete removal of burrs and increases the defective rate of a product.
The present invention discloses a device for removal of wheel rim burr which removes burrs on an edge of a spoke hole of a wheel rim automatically.
The device for removal of wheel rim burr of the present invention comprises a main body, plural positioning wheels, an eccentric wheel is disposed on the main body, and at least two brush wheels disposed between two corresponding positioning wheels. Accordingly, a wheel rim is placed on the plural positioning wheels and contacts the positioning wheels and the eccentric wheel by an outer side. The brush wheels contacts an inner side of the wheel rim. When the wheel rim is driven by the eccentric wheel to spin, and the wheel rim sways back and forth so as to increase friction between the inner side thereof and the brush wheels. Therefore, burrs on the edge of the spoke holes are removed automatically and thoroughly by the present invention.
Referring to
The plural positioning wheels (2) are disposed on the first end surface (11). Every two of the plural positioning wheels (2) are arranged opposite to each other, and the plural positioning wheels (2) are arranged in a semicircular path about a wheel rim (6).
The eccentric wheel (3) is disposed in a middle position below the two lowermost positioning wheels (2) of the plural positioning wheels (2) on the first end surface (11). The main body (1) is provided with a first rotary power source (31) disposed on the second end surface (12) thereof for connecting the eccentric wheel (3) by a first rotating shaft, and the first rotary power source (31) can be a reduction motor.
The at least two brush wheels (4) are disposed between the two corresponding positioning wheels (2) on the first end surface (11). The at is least two brush wheels (4) passes through the plural through holes (13) on the main body (1). Each of the at least two brush wheels (4) is provided with a second rotary power source (41) and the second rotary power source (41) is a motor. The second rotary power source (41) is disposed on the second end surface (12) of the main body (1) for connecting each of the at least two brush wheels (4) by a second rotating shaft. A telescopic power source (42) is further provided and is disposed on the second end surface (12) of the main body (1) next to the second rotary power source (41). The telescopic power source (42) connects the second rotary power source (41) by an output shaft thereof, and the telescopic power source (42) can be a pneumatic cylinder.
The present invention further comprises a collecting member (5) on the first end surface (11) below the plural positioning wheels (2) and the eccentric wheel (3). The collecting member (5) is a collecting tank (51) having an opening.

Referring to
After removing the burrs on the edges of the spoke holes (61) of the wheel rim (6), the first rotary power source (31) and the second rotary power source (41) are turned off, and the two brush wheels (4) are driven to move toward the second end surface (12) of the main body (1) by the two telescopic power sources (42) and placed in the through holes (13). After the two brush wheels (4) are moved into the through holes (13), the wheel rim (6) can be removed conveniently from the present invention for further processing.
Accordingly, the device for removal of wheel rim burr of the present invention removes burrs on edges of the spoke holes (61) of the wheel rim (6) automatically and thoroughly which saves mainpower for removing burrs on edges of the spoke holes (61) so as to reduce production cost. The present invention also prevents injuries of the workers removing burrs on the spoke holes (61) by using the sandpapers, the tools or the burrs on the spoke holes (61). Furthermore, the yield rate of the product is also increased since the present invention prevents incomplete removal of burrs by workers careless in operation.
