Description

Technical Field

[0001] The invention relates to the technical field of gear manufacturing, and in particular to a special deburring device for oil pump gears. Background Art

[0002] Gears are mechanical components with teeth on the rim that can continuously mesh to transmit motion and power. When manufacturing gears, it is necessary to remove the burrs on their surfaces, that is, to remove the thorns or flash formed at the intersection of the parts' surfaces.

[0003] At present, there are two ways to deburr the oil pump gear. One is to use a disc brush to rub the end face and tooth groove of the gear manually. The entire operation process is completely dependent on manual operation, which has high labor costs and is difficult to unify quality.

[0004] Another method is to use a machine to control a high-speed rotating disc brush to remove burrs. However, the high-speed rotating disc brush is too close to the gear and may cause certain damage to the gear. Therefore, when replacing the deburred gear groove, the disc brush needs to be stopped and restarted after the replacement is completed. The work efficiency is low and the disc brush needs to be started and stopped multiple times, which is very inconvenient. Summary of the invention

[0036] The deburring bristles 24 are ceramic fiber bristles.

[0037] In order to enhance the rotation stability of the rotating frame 2 , a bearing seat 25 is disposed on the frame 1 , and the rotating frame 2 is connected to the inner ring of the bearing seat 25 .

[0038] Working principle: When in use, place the gear on the placement plate 17 and engage it with the spiral strip 5 on the rotating disk 3, then start the two-way cylinder 18 to fix the gear, then start the first servo motor 20 and the second servo motor 22, and the gear will start to rotate under the drive of the rotating disk 3. At the same time, the rotating disk 3 drives the roller 11 to rotate, and then, with the cooperation of the guide rod 26 and the oblique annular groove 12, the sliding square rod 4 is driven to slide along the changes on the outer side of the gear, so that the disc brush 23 can constantly brush the gear teeth, greatly improving the deburring efficiency.
