Abstract

A cam lifting control system is used for lifting objects. The system comprises a cam lifting mechanism, a controller, an electromagnetic attraction device driving circuit, a motor driving circuit and a driving rotary shaft motor. The cam lifting mechanism is used for controlling an object to ascend and descend and comprises a rack (1), an eccentric wheel (2), a locking pin (3), an elastic push pin (4) and a limiting post (5). The eccentric wheel (2) is round as a whole and eccentrically provided with a driving rotary shaft (21). When the circle center of the round shape is located above the driving rotary shaft (21) and the circle center of the round shape and the driving rotary shaft (21) are in the vertical direction, the object (9) is lifted to a high position by the eccentric wheel (2). A locking hole (23) sunken inward in the radial direction is further formed in the circumferential face of the eccentric wheel (2), the locking hole (23) is used for being matched with the upper end of the locking pin (3), and when the object (9) is lifted to a high position by the eccentric wheel (2), the locking hole (23) is located below the driving rotary shaft (21) and the locking hole (23) and the driving rotary shaft (21) are in the vertical direction.

Description

[0001] technical field [0002] The present application relates to a lifting mechanism, in particular to a cam lifting control system. [0003] Background technique [0004] The cam mechanism is a high-level mechanism composed of three basic components: the cam, the follower and the frame. The cam is a component with a curved profile or a groove, generally a driving part, which performs constant-speed rotary motion or reciprocating linear motion. [0005] The component that is in contact with the cam profile, transmits power and realizes a predetermined law of motion, generally performs reciprocating linear motion or swings, and is called a follower, or an object that is lifted. [0006] The basic feature of the cam mechanism in application is that it can make the follower obtain more complex motion laws. Because the motion law of the follower depends on the cam profile curve, so in application, it is enough to design the cam profile curve according to the motion law o...
