Problems solved by technology

[0004] The movement process of the cam needs to be locked at different positions; and locking and unlocking require an actuator, which increases the cost of equipment and power; moreover, it cannot be locked immediately when needed and at the same time allows easy unlocking

Abstract

The invention provides a cam mechanism used for lifting an object (2). The cam mechanism comprises a cam (4), a driving rotation shaft (42) and a locking pin (5). The driving rotation shaft (42) is used for driving the cam (4) to rotate, the cam (4) is in the shape of an ellipse on the whole, the ellipse is provided with a short axis (x) and a long axis (y), and a vertex of the long axis (y) of the ellipse is a lifting position bearing area (8) which is used for bearing the object at the lifting position of the object. A lifting position locking notch (41) is formed in the position of the other vertex of the long axis (y) of the ellipse, the lifting position locking notch is matched with a head (51) of the locking pin at the lifting position, and therefore position locking is conducted. The locking pin is arranged in a vertical hole in the vertical direction, the tail end of the locking pin is connected with an elastic element (52), and therefore the locking pin is allowed to conduct expansion and retraction movement in the vertical hole in the vertical direction.

Description

technical field [0001] The invention relates to a cam, in particular to a cam mechanism 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 machin...
