Description

Technical Field

[0002] Automobile friction plates and clutch plates are common automobile parts. In order to improve the braking effect of automobile friction plates and the separation or engagement effect of clutch plates, it is necessary to process oil grooves on the surface of friction plates or clutch plates. Existing oil groove processing is generally modified by bench drilling machines, manual mechanical indexing plates and electromagnetic chucks. Although the slot milling cutter is driven by a motor to rotate automatically, the up and down movement of the milling cutter and the propulsion of the electromagnetic chuck still need to rely on manual operation, which has high labor intensity, too frequent manual operation by workers, low labor efficiency, low oil groove processing accuracy, and high scrap rate, which greatly affects the slotting of friction plates or clutch plates.

[0003] In order to solve the problems existing in the prior art, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a friction plate mesh oil groove processing device [application number: 201020296767.0]: it includes a body, a torque input gear, an additional gear set, a torque transfer gear, a gear changing mechanism, a reduction gear, a workpiece fixing disk, a rotating disk, and a processing tool. A torque input gear is installed on the right side of the body, one end of the additional gear set is meshed with the torque input gear, and the other end is meshed with the torque transfer gear.
