Problems solved by technology

[0003] The present invention mainly solves the problem that the existing overlapping locking structure between the chain links is too complicated, the sliding pin is unstable and reliable and easily deformed due to force, and the force between the sprocket and the transmission pin is single and easily deformed during transmission, resulting in inability to In order to solve the technical problems of low load-carrying performance and poor dimensional load-transfer stability in normal operation, a rigid chain push-pull actuator with simple structure, strong rigidity, large load-carrying capacity and continuous and stable performance is provided.

Abstract

The invention discloses a rigid chain push-pull execution mechanism. The mechanism comprises a rigid chain, a chain wheel and a bottom frame and is characterized in that the chain wheel is mounted inthe bottom frame, the rigid chain is meshed with the chain wheel and composed of multiple chain links, each chain link comprises a left chain plate and a right chain plate, and each left chain plate and the corresponding right chain plate which are identical in structure are connected with each other through a connecting pin and symmetrically arranged in a mirror mode in the left and right direction; the lower end of the rigid chain extends downward, a chain guide rail is embedded to the lower end of the rigid chain, and the upper end of the rigid chain is connected with a push-pull head. According to the rigid chain push-pull execution mechanism, the chain wheel can be used as a power drive to be connected with a driving shaft of a power motor; since the chain wheel is meshed with the rigid chain, the chain wheel rotates to drive the rigid chain to conduct push-pull load transfer.

Description

technical field [0001] The invention relates to the technical field of automatic equipment, in particular to a rigid chain push-pull actuator. Background technique [0002] Rigid chain (also known as drag chain) is a special chain, which has both the flexibility of ordinary chain and certain rigidity, so the actuator composed of rigid chain and driver can replace hydraulic cylinder, air cylinder and electric push rod etc. are widely used in occasions that require a large stroke to push the load, so as to reduce the volume of the equipment and save space. For example, a rigid chain push-pull actuator with a Chinese invention patent authorization announcement number of CN 103410934B, the push-pull actuator is composed of a rigid chain and a driver, wherein the rigid chain is composed of several chain links, and each chain link includes a Outer chain plates, a pair of inner chain plates, a transmission pin on one side of the chain link, a pair of outer chain plates and a pair ...
