Mechanism for converting linear reciprocating motion of air cylinder into periodic motion and work method thereof

Abstract

The invention discloses a mechanism for converting linear reciprocating motion of an air cylinder into periodic motion. The mechanism for converting the linear reciprocating motion of the air cylinderinto the periodic motion comprises the steps that a power source, a double-rack mechanism and a cam mechanism, wherein the power source, the double-rack mechanism and the cam mechanism can achieve reciprocating motion. The power source is connected with the double-rack mechanism. The cam mechanism is provided with a transmission mechanism. The end, far away from the cam mechanism, of the transmission mechanism is provided with an incomplete gear. The incomplete gear is arranged inside the double-rack mechanism and matched with the double-rack mechanism. An execution mechanism is arranged on one side of the cam. The two actions of triggering and return of the power source are converted into unidirectional continuous rotation of the incomplete gear in the manner that the double-rack mechanism and the incomplete gear are in meshed transmission, and the linear reciprocating motion of the power source is converted into rotational motion of the incomplete gear; and then, motion transmissionis conducted through the transmission mechanism, output motion of the air cylinder is transmitted to the cam mechanism, so that period adjustment is achieved in the manner that the cam mechanism intermittently moves, in this way, the reaction period of the execution mechanism is greatly shortened, and the response speed of the execution mechanism is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a mechanism for converting linear reciprocating motion of a cylinder into periodic motion. Background technique [0002] Pneumatic transmission and control is one of the most effective means of automation and mechanization of the production process. Pneumatic devices are widely used in automated production lines due to their simple structure, safe use, environmental protection, and easy pressure adjustment. Cylinder is one of the most commonly used pneumatic devices, and it is often used as actuators such as clamping and positioning of automation equipment. Periodic motion control in an automated production line is an important means to realize each process operation and process conversion. There are two main types of periodic motion control methods commonly used: one is to realize periodic motion control through mechanical structure design; the other is to realiz...

Problems solved by technology

However, the motion of the cylinder belongs to the linear reciprocating fixed-period motion. When the response period of the actuator is different from the action period of the cylinder, it is difficult to realize the output period.
