Deburring apparatus

Abstract

A deburring apparatus is provided for automatically deburring gears having a plurality of external or internal extending teeth formed therealong at predetermined intervals from each other. The apparatus comprises a frame having a spindle on which the gear to be deburred is mounted. A main shaft is rotatably supported within the frame which, upon rotation, incrementally indexes the gear mounted on the spindle for a distance corresponding to the distance between adjacent gear teeth and, after doing so, interrupts the rotation of the spindle for a predetermined period of time. Both an eccentric member and a cam are secured to the shaft. In addition a cutting tool arm is rotatably secured at one end to the eccentric member and, at its other end, a cutting tool is mounted. A bell crank is also pivotally secured to the frame and has a cam follower mounted to one end which engages the cam. A roller is secured to the other end of the bell crank which abuts against the cutting tool arm so that pivotal action of the bell crank due to the cam imparts a corresponding pivotal action to the cutting tool arm. The eccentric member and cam work in conjunction with each other to pivot and position the cutting tool arm during the predetermined time period when the gear is stationary so that the cutting member engages the space or trough between the gear teeth and, by a cutting action, removes any burrs from the gear. Prior to the next incremental rotation of the gear via the spindle, the eccentric member and cam retract and pivot the cutting tool arm and its attached cutting tool outwardly and away from the gear on the spindle.
