Abstract

A cam system for lifting an object 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 rotating shaft (42) and a locking pin (5), the driving rotating shaft (42) is in linkage with the motor and is used for driving the cam (4) to rotate, the overall shape of the cam (4) is an oval, and the oval has a short axis (x) and a long axis (y). A lifting position bearing area (8) is arranged on one top point of the long axis (y) of the oval, and is used for bearing the object (2) at the lifting position of the object (2), a lifting position locking concave opening (41) is arranged on the other top point of the long axis (y) of the oval, and the lifting position locking concave opening (41) is matched with a head (51) of a locking pin (5) at the lifting position.

Description

technical field [0001] The invention relates to a cam, in particular to a cam system for lifting objects. 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 automatic machinery...
