[0032] Working principle: When the gear deburring and grinding device is in use, the staff turns on the first motor 4, so that the first motor 4 drives the first limit plate 5 and the rotating plate 6 to rotate synchronously. When the first limit plate 5 and the rotating plate 6 rotate synchronously, the rotating plate 6 drives the column 10 to make a circular motion on the rotating plate 6. When the rotating plate 6 rotates to the side close to the intermittent plate 7, the driving column 10 slides into the displacement groove 9. Then, the driving column 10 drives the intermittent plate 7 to rotate ninety degrees through the displacement groove 9.

Otherwise, the processed gear can be disassembled. When the cross block 3 rotates intermittently, the driven gear 15 will be disengaged from the driving gear 17, and the other driven gear 15 will be rotated up through the cross block 3. At this time, the driving gear 17 is in a state of rotation at an appropriate speed. When the teeth of the driven gear 15 contact the teeth of the driving gear 17, the driven gear 15 will press the slider 20 downward through the first limiting column 18, and the slider 20 will slide downward inside the slide groove 22. When the driven gear 15 does not mesh with the driving gear 17 when it comes up, the driving gear 17 is constantly rotating at this time. When it rotates to a suitable angle, the slider 20 will lift the slider 20 through the action of the spring 23, thereby lifting the driven gear 15, so that the driven gear 15 is meshed with the driving gear 17, and the driving gear 17 drives the driven gear 15 to rotate, and the driven gear 15 drives the first limiting column 18 to rotate, and the first limiting column 18 will squeeze and rotate the processed gear through the two second limiting plates 16, thereby realizing the rotation of the gear, and the gear is polished and deburred by the abrasive wire disc brush set on the support frame 1.
