Detailed Description
The utility model is further described below with reference to the accompanying drawings.
As shown in fig. 1-3, a polishing device for rim processing comprises a workbench 1, a turntable 2 is rotatably arranged in the middle of the workbench 1, a rotating shaft is connected below the turntable 2, after the rotating shaft penetrates through the workbench 1, the lower end of the rotating shaft is connected with an output shaft of a motor 16, the motor 16 is arranged on the lower surface of the workbench 1, arc polishing seats 4 are symmetrically arranged on two sides of the workbench 1, a supporting frame 5 is horizontally connected to the outer side of the polishing seat 4, sliding blocks 8 are symmetrically connected to the two sides of the outer end of the supporting frame 5, the sliding blocks 8 are matched with sliding rails 9, the sliding rails 9 are arranged on the workbench 1, the outer side of the supporting frame 5 is connected with telescopic rods of air cylinders 6, the air cylinders 6 are arranged on cylinder seats 7, and the cylinder seats 7 are arranged at the end parts of the workbench 1.
As a further improvement to the scheme, the two ends of the polishing seat 4 are symmetrically and integrally connected with the end head 11 with the cross section consistent with that of the polishing seat 4, the end head 11 is sleeved with a fixing seat 12, and the fixing seat 12 is provided with a limit bolt 13; the abrasive belt is attached to the intrados of the grinding seat 4 so as to achieve effective smooth grinding treatment of the outer edge of the rim (hub).
As a further improvement to the scheme, a hole 14 matched with the cross section of the end head 11 is arranged in the fixing seat 12 in a penetrating way, and the width of the hole 14 is larger than the thickness of the cross section of the end head 11; the abrasive belt is convenient to insert into the hole 14 of the fixed seat 12, and is limited and fixed by the limiting bolt 13.
