Abstract

A wheel grinding device consists of a lower lifting rotary system, spoke grinding units, a center hole grinding system and an upper lifting and clamping rotary system. The wheel grinding device not only can be used for grinding the center hole of a wheel of any size via brush units of the center hole grinding system, but also can be used for grinding the back of wheel spokes of different sizes and shapes via the actions of brush belts of the spoke grinding units.

First claim

The invention claimed is:

1. A wheel grinding device comprising a lower lifting rotary system, four spoke grinding units, a center hole grinding system and an upper lifting and clamping rotary system, wherein:
the lower lifting rotary system includes: two third cylinders and four lower guide sleeves all fixed on a lower fixed plate, and four lower guide posts fixed below a lower lifting plate, wherein each of the four lower guide posts is matched with a respective one of the four lower guide sleeves; output ends of the two third cylinders are hinged with a lower part of the lower lifting plate; a first bearing seat is fixed above the lower lifting plate, and a first shaft is installed inside the first bearing seat via a first bearing; a first belt pulley is fixed below the first shaft; a first servo motor is fixed below the lower lifting plate, and a second belt pulley is fixed at an output end of the first servo motor; and the first belt pulley is connected with the second belt pulley via a first synchronous belt;
each of the four spoke grinding units includes: a vertical plate installed on an upper side of the first shaft via a first guide rail; a first rack is also fixed on the upper side of the first shaft; a third servo motor is fixed on a left side of the vertical plate, a first gear is fixed at an output end of the third servo motor, and the first gear is engaged with the first rack; a transverse plate is fixed below the vertical plate; a transverse sliding plate is installed above the transverse plate via a second guide rail; a second bearing seat is fixed above the transverse sliding plate; a second shaft is installed in a middle of the second bearing seat via a second bearing; a fourth servo motor is fixed below the transverse sliding plate, and an output end of the fourth servo motor is connected with a lower part of the second shaft; a rotary rack is fixed above the second shaft; a third belt pulley and a fourth belt pulley are installed above the rotary rack and connected with each other via a brush belt; a fifth servo motor is installed on a side of the rotary rack, and an output end of the fifth servo motor is connected with the third belt pulley; a third rack is installed above the transverse plate; an eighth servo motor is fixed on an upper side of the transverse sliding plate, and a third gear is fixed at an output end of the eighth servo motor; and the third gear is engaged with the third rack; wherein the four spoke grinding units are fully symmetric;
the center hole grinding system includes: a partition plate fixed above a middle hole of the first shaft; a lifting sleeve is matched with an inner wall of a hole at an upper part of the first shaft; a first servo electric cylinder is fixed below the partition plate, and an output end of the first servo electric cylinder is connected with a bottom of the lifting sleeve; a third bearing seat is fixed above a top plate of the lifting sleeve; a third shaft is installed inside the third bearing seat via a third bearing; a second servo motor is fixed below the top plate of the lifting sleeve, and an output end of the second servo motor is connected with a lower part of the third shaft; a fixed block is fixed above the third shaft; a nut is provided with threads at an upper part of the nut and installed inside the fixed block via a fourth bearing; a sixth servo motor is fixed below the fixed block, and an output end of the sixth servo motor is connected with a lower part of the nut; a chute is fixed above the fixed block; four sliding blocks are matched with T-shaped slots in the chute; the four sliding blocks are uniformly distributed in a circumferential direction; bottoms of the four sliding blocks are provided with threads, which are matched with the threads at the upper part of the nut; brush units are matched with holes at upper parts of the four sliding blocks; a plurality of springs are installed in the holes at the upper parts of the four sliding blocks and each of the plurality of springs is placed on one side of a corresponding brush unit of the brush units;
the upper lifting and clamping rotary system includes: a second gear fixed in a middle below an upper fixed plate; a left sliding plate and a right sliding plate are installed below the upper fixed plate via two third guide rails; two clamping jaws are respectively fixed below the left sliding plate and the right sliding plate, and two second racks area respectively fixed above the left sliding plate and the right sliding plate; the two second racks are simultaneously engaged with the second gear; a first cylinder is fixed below the upper fixed plate, and an output end of the first cylinder is connected with an upper part of the left sliding plate; a fourth bearing seat is fixed below an upper lifting plate; a fourth shaft is installed inside the fourth bearing seat via a fifth bearing; a lower part of the fourth shaft is connected with a top of the upper fixed plate; a seventh servo motor is fixed above the upper lifting plate, and an output shaft of the seventh servo motor is connected with an upper part of the fourth shaft; four upper guide posts are fixed above the upper lifting plate; four upper guide sleeves are fixed at a top of a frame, wherein each of the four upper guide sleeves is matched with a respective one of the four upper guide posts; two second cylinders are also fixed at the top of the frame, and output ends of the two second cylinders are hinged with an upper end of the upper lifting plate.
