Problems solved by technology
[0003] However, the traditional cam mechanism has the following three disadvantages: 1. Once the profile of the cam is processed, it cannot be adjusted, so that the trajectory of the follower is fixed, and the trajectory of the follower cannot be modified.
2. It is difficult to ensure good lubrication at the contact between the follower and the cam profile surface, and it is easy to wear because of its high specific pressure. In order to maintain the necessary life, the transmission power should not be too large
3. The length of the cam mechanism cannot be adjusted

The present invention disclosed a variable outline digital flexible mobile cam, including restricted components, which include a symmetrical limit board, which is installed with a fixed component on the outside of the limit plate, which is symmetrical.The cam is installed between the tablet, which includes several cams arranged in parallel arranged, and the adjacent cam unit is installed with a second screw between the cam.The rolling needle unit includes a rectangular block, which is installed with a connecting seat at the center of the rectangular block, which is equipped with a digital electromagnetic driver lifting mechanism at the bottom of the connected seat.EssenceBy rotating the length of the camstame of the second screw, the rolling needle digital electromagnetic drive elevation mechanism is used to adjust the relative position of the upper and lower directions between the roller unit to change the outline of the moving cam, so that the outline of the cam can be adjusted, and then modify the fromMovement trajectory of the moving part.
Description
technical field [0001] The invention relates to the technical field of cam mechanisms, in particular to a digital flexible moving cam mechanism with variable contours. Background technique [0002] The cam mechanism is a high auxiliary mechanism that makes the follower move to the expected regularity. The cam mechanism is generally used to move the follower to the place where the regularity is strictly required or where the follower moves intermittently. As long as the corresponding cam profile is designed, the follower can be moved according to the proposed law. [0003] However, the traditional cam mechanism has the following three deficiencies: 1. Once the cam profile is processed, it cannot be adjusted, so that the trajectory of the follower is fixed, and the trajectory of the follower cannot be modified. 2. It is difficult to ensure good lubrication at the contact between the follower and the cam profile surface, and because of its large specific pressure, it is easy t...
