[0020] The four pre-positioning guide rails 16 are symmetrically mounted on the frame 1, and the sliding plate I 17 and the sliding plate II 18 are respectively mounted on the pre-positioning guide rails 16 and driven by the pre-positioning cylinders 15. Two pre-positioning posts 19 are mounted on the sliding plate I 17, another two pre-positioning posts 19 are also symmetrically mounted on the sliding plate II 18, and the corner cylinder pressure claws 20 are mounted on the pre-positioning posts 19. When the left and right pre-positioning cylinders 15 drive the sliding plate 117 and the sliding plate II 18 to move synchronously, the four pre-positioning posts 19 can pre-position a wheel; and after pre-positioning of the wheel is completed, the pre-positioning cylinders 15 drive the sliding plate I 17 and the sliding plate II 18 to synchronously retract a distance, the four pre-positioning posts 19 do not contact the wheel any more, the clearance is preferably 2-3 mm, and the clearance is reserved for precision positioning.

[0021] The two jacking cylinders 2 and the four guide posts 3 are mounted at the bottom of the frame 1, the output ends of the jacking cylinders 2 are connected with the lifting table 5, the servo motor 4 is mounted on the lifting table 5, the output end of the servo motor 4 is connected with the rotating table 9 via the shaft 7, the bearing 8 and the bearing seat 6, the rotating table 9 can be driven to move up and down by extension and retraction of the jacking cylinders 2, and the servo motor 4 can drive the rotating table 9 to rotate.

[0022] The two adjusting guide rails 10 are mounted on the rotating table 9, the left sliding table 12 and the right sliding table 14 are symmetrically mounted on the adjusting guide rails 10 and connected by the gear rack 13, the adjusting cylinder 11 is fixed on the side of the rotating table 9, and the output end of the adjusting cylinder 11 is connected with the left sliding table 12. The left burr cutter 21 and the right burr cutter 22 are symmetrically mounted on the left sliding table 12 and the right sliding table 14, the top of the left burr cutter 21 is composed of a left precision positioning surface 210 and a left cutting edge 211, and the top of the right burr cutter 22 is composed of a right precision positioning surface 220 and a right cutting edge 221. The left precision positioning surface 210 and the right precision positioning surface 220 constitute a precision positioning system, and the left cutting edge 211 and the right cutting edge 221 constitute a cutter system. When the adjusting cylinder 11 drives the left sliding table 12 and the right sliding table 14 to move synchronously, the distance between the left precision positioning surface 210 and the right precision positioning surface 220 can be adjusted to match the diameter side of a cap seam allowance, thereby realizing precision positioning; and the distance between the left cutting edge 211 and the right cutting edge 221 can also be adjusted to contact cap section burrs. The precision positioning system and the burr removing cutter system are integrated to reduce the combined error, and the rotating centers of the burr cutters are superposed with the central axes of the cap section burrs to realize high-precision burr removal, thereby effectively solving the problems of deviation and non-uniformity of burr removal at the cap section.

[0023] The working process of the device is as follows: firstly, the left and right pre-positioning cylinders 15 are synchronously started to drive the sliding plate I 17 and the sliding plate II 18 to move synchronously, the four pre-positioning posts 19 can pre-position a wheel; and after pre-positioning of the wheel is completed, the pre-positioning cylinders 15 drive the sliding plate I 17 and the sliding plate II 18 to synchronously retract a distance, the four pre-positioning posts 19 do not contact the wheel any more, the clearance is preferably 2-3 mm, and the clearance is reserved for precision positioning. Then, the jacking cylinders 2 are started to drive the rotating table 9 to ascend; when the positioning surfaces of the left burr cutter 21 and the right burr cutter 22 reach the cap seam allowance of the wheel, the rotating table 9 stops ascending, at the moment, the adjusting cylinder 11 is started to adjust the distance between the left burr cutter 21 and the right burr cutter 22, the left precision positioning surface 210 and the right precision positioning surface 220 contact the diameter side of the cap seam allowance to hold the cap seam allowance of the wheel tightly, and precision positioning of the wheel is thus completed; and after precision positioning of the wheel, the corner cylinder pressure claws 20 are started to press the wheel. Next, the adjusting cylinder 11 is continuously started to shorten the distance between the left burr cutter 21 and the right burr cutter 22, the positioning surfaces leave the sides of the cap seam allowance, and then the jacking cylinders 2 are started to drive the burr cutters to ascend; when the cutting edges of the burr cutters reach the height of the cap section burrs, the burr cutters stop ascending, at the moment, the adjusting cylinder 11 is restarted to adjust the distance between the left cutting edge 211 and the right cutting edge 221, and the cutting edges contact the cap section burrs; and finally, the servo motor 4 drives the rotating table 9 to rotate one circle, and the cutting edges of the burr cutters remove the ring of burrs. After the burrs are removed, the positioning system and the cutter system are reset, this is a cyclic working process of the device, and so on.
