High-precision wheel cap section burr removing device

A high-precision wheel cap section burr removing device, comprising a frame, jacking cylinders, guide posts, a servo motor, a lifting table, a bearing seat, a shaft, a bearing, a rotating table, adjusting guide rails, an adjusting cylinder, a left sliding table, a gear rack, a right sliding table, pre-positioning cylinders, pre-positioning guide rails, a sliding plate I, a sliding plate II, pre-positioning posts, corner cylinder pressure claws, a left burr cutter and a right burr cutter, wherein the left burr cutter and the right burr cutter are symmetrically mounted on the left sliding table and the right sliding table, the top of the left burr cutter comprises a left precision positioning surface and a left cutting edge, the top of the right burr cutter comprises a right precision positioning surface and a right cutting edge, the left precision positioning surface and the right precision positioning surface constitute a precision positioning system, and the left cutting edge and the right cutting edge constitute a cutter system;

• the left sliding table and the right sliding table are connected by the gear rack, the adjusting cylinder is fixed on the side of the rotating table, and the output end of the adjusting cylinder is connected with the left sliding table;
• the working process of the device is as follows:
• firstly, the left and right pre-positioning cylinders are synchronously started to drive the sliding plate I and the sliding plate II to move synchronously, the four pre-positioning posts can pre-position a wheel;
• and after pre-positioning of the wheel is completed, the pre-positioning cylinders drive the sliding plate I and the sliding plate II to synchronously retract a distance, the four pre-positioning posts 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 are started to drive the rotating table to ascend;
• when the positioning surfaces of the left burr cutter and the right burr cutter reach the cap seam allowance of the wheel, the rotating table stops ascending, at the moment, the adjusting cylinder is started to adjust the distance between the left burr cutter and the right burr cutter, the left precision positioning surface and the right precision positioning surface 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 are started to press the wheel;
• next, the adjusting cylinder is continuously started to shorten the distance between the left burr cutter and the right burr cutter, the positioning surfaces leave the sides of the cap seam allowance, and then the jacking cylinders 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 is restarted to adjust the distance between the left cutting edge and the right cutting edge, and the cutting edges contact the cap section burrs;
• and finally, the servo motor drives the rotating table to rotate one circle, and the cutting edges of the burr cutters remove the ring of burrs.
