Auxiliary device for assembling star wheel roller and spring of isolator

Abstract

The invention discloses an auxiliary device for assembling an isolator star wheel roller and a spring. The spring assembling precision is guaranteed while the spring feeding speed is increased, and therefore the production efficiency is improved. Comprising a material distributing assembly and a pre-assembling assembly which are both arranged on a working table where a mounting frame is located, and the material distributing assembly and the pre-assembling assembly are connected through a spring conveying rail used for conveying springs in a mutual abutting state. The distributing assembly comprises at least two limiting pieces which are driven by a driving mechanism so as to separate the springs in the spring conveying rail one by one in sequence. The pre-assembling component comprises a compression part for compressing the single spring treated by the limiting part and a pre-assembling groove which is communicated with the spring conveying rail and is used for accommodating the spring in a compressed state; the whole device is high in production efficiency, and precision meets process requirements. The invention is mainly used in the technical field of isolator production and processing.

Description

technical field [0001] The invention relates to the technical field of production and processing of unidirectional devices, in particular to an auxiliary device for assembling a unidirectional device star wheel roller and a spring. Background technique [0002] The one-way device, also known as the overrunning clutch, is an important part used for power transmission and separation between the prime mover and the working machine or between the driving shaft and the driven shaft inside the machine, including the star wheel and the assembly groove assembled in the star wheel. When assembling, the star wheel is first limited under the action of the limiting mechanism, and then a single spring is processed into a compressed state and abutted with a roller, and then the compressed spring and roller Fit into the mounting groove of the star wheel. [0003] Specifically, the roller is a component that is not easily deformed due to its heavy self-weight, and does not need to be pretr...

Problems solved by technology

[0004] But the spring is in light weight and easy-to-deform components, and it needs to be compressed. The existing publication number is "CN206702576U". The method is to limit the spring to fall into the track in the way of free fall through the channel and then perform compression treatment. Since the spring is a member that is easy to deform and has elasticity, the way of free fall can easily cause the spring to rebound after falling into the track. It is difficult to enter the track perpendicular to the track. When the spring and the track are in a non-perpendicular state, it may cause it to fail to enter the assembly groove of the star wheel and affect the subsequent assembly accuracy.

[0005] In order to improve the problem of assembly accuracy, the spring roller assembly of the Chinese patent one-way device assembly system with the publication number "CN211708615U" is equipped with a feeding mechanism, and the springs are individually loaded sequentially by manual feeding, but this type of feeding The efficiency of the method is relatively slow, the assembly process is relatively cumbersome, the production efficiency is reduced, and the spring needs to be driven by power many times. During the continuous driving process, a single spring is also prone to angle deviation, which in turn affects the progress of assembly.
