DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0012] Referring to FIG. 1 and FIG. 2, a device for removal of wheel rim burr of the present invention comprises a main body (1), plural positioning wheels (2), an eccentric wheel (3) and at least two brush wheels (4). The main body (1) has a first end surface (11), a second end surface (12) opposite to the first end surface (11), and plural through holes (13) penetrating the first end surface (11) and the second end surface (12).

[0013] 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).

[0014] 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.

[0015] 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.

[0016] 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.

[0017] Referring to FIG. 3 to FIG. 5, a working state of the present invention is disclosed. The wheel rim (6) having plural spoke holes (61) on an internal side is placed on the plural positioning wheels (2) for positioning, and the wheel rim (6) contacts the positioning wheels (2) by an outer side. In addition, the wheel rim (6) placed on the plural positioning wheels (2) contacts the eccentric wheel (3) by a bottom of the outer side. The two telescopic power sources (42) are driven to extend the two brush wheels (4) from the first end surface (11) of the is main body (1), and the two brush wheels (4) contact an internal side of the wheel rim (6).

[0018] Referring to FIG. 6, the first rotary power source (31) is turned on to drive the eccentric wheel (3) to spin, and then the eccentric wheel (3) drives the wheel rim (6) to spin. The second rotary power source (41) is also turned on to drive the two brush wheels (4) to spin and grind burrs on the edges of the spoke holes (61) of the wheel rim (6). At the meantime, the spinning wheel rim (6) also sways back and forth so as to increase friction between the edges of the spoke holes (61) of the wheel rim (6) and the brush wheels (4). Therefore, the brush wheels (4) remove the burrs on the edges of the spoke holes (61) completely. The burrs removed from the spoke holes (61) of the wheel rim (6) is collected by the collecting tank (51) of the collecting member (5) below the plural positioning wheels (2) and the eccentric wheel (3).

[0019] 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.

[0020] 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.
