Description

Technical Field

[0002] Planetary gears are a special type of gear system. In addition to being able to rotate around their own axes of rotation like fixed-axis gears, their axes of rotation also rotate around the axes of other gears along with the planetary carrier.

[0003] During the production of planetary gears, their surface quality will be improved so that they can be cut. Before processing, they will be clamped and fixed to facilitate subsequent processing operations.

[0004] Some machine tools use threaded rods to clamp planetary gears. The planetary gears are first placed on the fixture, and then the threaded rods on both sides are rotated to clamp and fix the planetary gears. Then the corresponding cutting tools are started to process the planetary gears. However, it is troublesome to repeatedly rotate the threaded rods during clamping, and rotating the threaded rods for a long time will cause the threaded rods to wear, which makes the subsequent rotation more laborious. Therefore, a multi-station cutting machine tool for planetary gears is proposed to solve the above problems. Utility Model Content
