Description
Technical Field
[0001] The utility model relates to the technical field of cam adjusting devices, and more specifically, to a high-efficiency cam adjusting device. Background Art
[0002] A cam is a component with a specific shape, usually circular or cylindrical. Its main function is to drive the follower in contact with it to produce the expected movement through its own rotation or movement. It can realize complex movements, and the cam structure is composed of fewer components, which is easy to install, maintain and manufacture. In many mechanical systems, the cam device plays a vital role. Most of the cams in the existing cam devices are sleeved on the outer surface of the bearing, and the cam is fixed by the left and right screw covers on the outer surfaces of both sides of the cam. Generally, one screw cover is fixed on the outer surface of the bearing, and the other screw cover slides on the outer surface of the bearing, so as to facilitate the replacement of the bearing. When the motion amplitude of the follower needs to be changed, it is necessary to rotate the screw cover to make the cam move, and then replace the cam. Most cams are an integral part and cannot be adjusted to change the motion amplitude of the follower, thereby greatly increasing the adjustment time of the cam device and reducing the working efficiency of the cam device to a certain extent. In order to solve the shortcomings of the prior art, we propose an efficient cam adjustment device. Utility Model Content
