Embodiment Construction

[0020] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0021] The step chain is composed of inner chain links, outer chain links, and step outer chain links, which are composed of multiple chain links connected in series by a hinge pair composed of a sleeve and a pin shaft or a sleeve and a step pin shaft. The manufacturing process of the stepped chain includes the chain plate blanking process, the chain link press-fitting process, and the chain assembly process. And the manufacturing process of required other parts on the step chain is no longer repeated in this description. The invention discloses a step chain same-side assembling method, which specifically includes a chain plate blanking process, a chain link press-fitting process and a chain assembling process. The chain plate blanki...

Abstract

The invention discloses a step chain same-side assembling method, and relates to the technical field of step chain assembling. Signs on a chain plate are used for recognizing an assembling datum so as to improve step chain assembling precision. Manufacturing of a step chain includes a chain plate blanking process, a chain link pressing process and a chain assembling process. The chain plate blanking process includes chain plate dropping, primary punching and secondary punching. The signs on the chain plate are completed in the chain plate blanking process. The chain link pressing process includes chain link pressing, and the signs on the chain plate must be located at the same side in the chain link pressing process. The chain assembling process includes segmented and striped assembling of the step chain, and the signs on the chain plate must be located at the same side in the chain assembling process. The signs on the chain plate are both used as the datum in the manufacturing processes of the step chain and are further placed at the same side, the step chain assembling precision is improved and the passenger comfort level of an escalator with the step chain is also improved.

Description

technical field [0001] The invention relates to the technical field of step chain assembly field, in particular to a step chain same-side assembling method. Background technique [0002] At present, step chains are widely used in escalators for transmission, lifting and conveying. In the escalator system, the step chain is a key component, which not only ensures the safety of passengers during the operation of the escalator, but also ensures the comfort of the passengers during the operation of the escalator. At present, most of the existing technologies are expounding on improving production efficiency and reducing the labor intensity of workers in the assembly process by developing automated equipment. In the prior art, the stepped chain includes a plurality of chain links, which are composed of an inner chain link and an outer chain link. The inner chain link is composed of an inner chain plate, a sleeve, and a roller. Two adjacent inner chain links use a sleeve and a pi...
