First claim

The invention claimed is:

1. A device for milling wheel window burrs on a production line, comprising a frame, a first base plate, a lifting cylinder, a first bracket, a bearing base, a linear bearing, a mounting plate, a guide shaft, a lifting shaft, a first servo motor, a first synchronous pulley, a connecting plate, a synchronous belt, a second synchronous pulley, a base, a first connecting shaft, a second servo motor, a first shaft sleeve, a lower end cover, a second connecting shaft, a second shaft sleeve, a cylinder, a first bearing, an end cover, a first gland, second bearings, a second base plate, a flange plate, pins, eight springs, eight expansion flaps, a third connecting shaft, a guard, an expansion core, a third servo motor, a third shaft sleeve, a third bearing, a rotating shaft, a second gland, a milling cutter and a six-axis manipulator, wherein
the device further comprises:
a lifting portion, in which the first base plate is fixed on the frame, the mounting plate is fixed on the first base plate via the first bracket, the bearing base and the lifting cylinder are fixed on the mounting plate, the lifting shaft is mounted on the bearing base via the linear bearing, two ends of the lifting shaft are respectively connected with the connecting plate and an output shaft of the lifting cylinder, and the lifting cylinder drives the mounting plate to move up and down via the linear bearing;
a rotating portion, in which the first servo motor and the base are fixed on the connecting plate, the first shaft sleeve is mounted on the base via the first bearing and the end cover, the first synchronous pulley and the second synchronous pulley are respectively connected with the first connecting shaft and an output shaft of the first servo motor, and the synchronous belt is connected with the first synchronous pulley and the second synchronous pulley respectively;
a clamping expansion portion, in which the lower end cover, the first gland and the second base plate are fixed on the first shaft sleeve, the second servo motor is mounted on the lower end cover, the second shaft sleeve is mounted on the first shaft sleeve via two columns of the second bearings and the first gland, the cylinder is fixed inside the second shaft sleeve, an output end of the cylinder is connected with the second connecting shaft, the second servo motor is connected with the second shaft sleeve via the second connecting shaft, the expansion core is connected with the second shaft sleeve via the third connecting shaft, the expansion core, the third connecting shaft and the second shaft sleeve are circumferentially locked without relative rotation, the third connecting shaft and the second shaft sleeve are movable axially relative to each other, the flange plate is fixed on the second base plate, eight uniformly distributed T-shaped chutes are formed in an inner cavity of the flange plate and the second base plate, bottom surfaces of the eight expansion flaps are T-shaped structures formed respectively in one-to-one correspondence with the eight uniformly distributed T-shaped chutes, each of the eight expansion flaps is slideable in a respective one of the eight uniformly distributed T-shaped chutes, an inner side wall of each expansion flap of the eight expansion flaps is inclined at 15° relative to an axis of the expansion flap, and two ends of the eight springs are respectively connected with the flange plate and the eight expansion flaps; a lateral surface of the expansion core comprises a first and second groups of inclined surfaces, each of the first and second groups of inclined surfaces is inclined at 15° relative to an axis of the expansion core, the first and second groups of inclined surfaces are uniformly spaced in a circumferential direction of the expansion core, the number of each group of inclined surfaces is 8, the first and second groups of inclined surfaces have a height difference, and the upper side walls of the first and second groups of inclined surfaces are intersected at tapered surfaces; when the expansion core is at a bottom under co-action of a pulling force of the cylinder and the elasticity of the eight springs, side walls of the eight expansion flaps are in contact with the tapered surfaces of the expansion core; the second servo motor drives the expansion core to rotate 22.5° via the second connecting shaft, the second shaft sleeve and the third connecting shaft, inclined surfaces matched with the eight expansion flaps are switched between the first and second groups of inclined surfaces of the expansion core; the cylinder drives the third connecting shaft and the expansion core to move up and down, the eight expansion flaps move synchronously centripetally and centrifugally in the eight uniformly distributed T-shaped chutes formed in the inner cavity of the flange plate and the second base plate through cooperation of the inner side walls of the eight expansion flaps and the first and second groups of inclined surfaces of the expansion core, and the eight expansion flaps realize synchronous expansion and contraction functions; since the first and second groups of inclined surfaces spaced uniformly on the lateral surface of the expansion core have the height difference, when the second servo motor drives the expansion core to rotate 22.5°, the inclined surfaces matched with the eight expansion flaps are switched between the first and second groups of inclined surfaces of the expansion core, thus, expansion and contraction diameters of the eight expansion flaps change in two different ranges; and

a milling portion, in which the third servo motor and the third shaft sleeve are fixed on the six-axis manipulator, the second gland and the third bearing enclose the rotating shaft inside the third shaft sleeve, the third servo motor is connected with the rotating shaft, and the milling cutter is fixed on the rotating shaft.

2. The device for milling wheel window burrs on a production line according to claim 1 , wherein the second base plate and the flange plate are provided with corresponding pin holes, and the pins are respectively connected with the pin holes of the second base plate.
