Technical Field

[0001] The utility model relates to the technical field of tooling, and particularly relates to a milling groove tooling for a cam follower. Background Art

[0002] A cam mechanism is a higher pair mechanism composed of three basic components: a cam, a follower, and a frame. The cam is a component with a curved profile or groove. Generally, the cam, as the driving member, makes a uniform rotational motion or a reciprocating linear motion. The cam mechanism is widely used in fields such as light industry, textile, food, transportation, and mechanical transmission.

[0003] A cam follower is a component in a cam mechanism that directly obtains motion from the cam. During its processing operation, a groove needs to be milled at one end of the follower. When milling the groove of the cam follower, a tooling is required to fix it. The existing tooling has an unstable clamping situation when fixing the cam follower, which affects the machining accuracy. Therefore, we propose a milling groove tooling for a cam follower.
