Abstract

The invention provides a method for lifting an object through a cam system. The cam system comprises a cam mechanism, a DSP controller, a motor driving circuit and a motor. The DSP controller controls the motor to rotate through the motor driving circuit. The cam mechanism comprises a cam (4), a driving rotary shaft (42) and a stop pin (5), wherein the driving rotary shaft (42) is used for driving the cam (4) to rotate, the whole shape of the cam (4) is an oval, the oval is provided with a short axis (x) and a long axis (y), one peak of the long axis (y) of the oval is a lifting position bearing zone (8) used for bearing the object when the object (2) is in the lifting position, and the other peak of the long axis (y) of the oval is provided with a lifting position locking notch (41).

Description

technical field [0001] The invention relates to a cam, in particular to a method for lifting an object by a cam system. Background technique [0002] 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. The component that is in contact with the cam profile and transmits power and realizes a predetermined law of motion generally performs reciprocating linear motion or swings, and is called a follower. [0003] 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 of the follower. Cam mechanisms are widely used in various autom...
