Belleville spring assembly detection device

Abstract

The invention discloses a belleville spring assembling and detecting device. The device comprises a laser contourgraph, a fixing support, a suspension arm, a hanging seats and a guide sliding rod; twosides of the lower portion of the fixing support are respectively provided with the hanging seats; two ends of the guide sliding rod are respectively connected with the hanging seats; the hanging armis connected with the guide sliding rod and can move left and right on the guide sliding rod; the laser contourgraph is fixed to the hanging arm; and the laser emitting direction and a belleville spring on a turbine shell are located on a same horizontal plane. During detection, the belleville spring to be detected is installed above a lining; the laser contourgraph judges whether assembly of thebelleville spring is qualified or not by detecting the position deviation of two points at the maximum outer diameter position on the section of the belleville spring piece, and rocker arm assemblingof the subsequent procedure is conducted after assembly of the belleville spring is confirmed to be qualified. Whether the belleville spring is correctly installed or not can be automatically recognized, and assembling correctness of the belleville spring can be accurately recognized when workpieces are assembled on a large scale, so that the percent of pass of products is increased, detection parameters can be freely set, and the method can be suitable for different product lines.

Description

technical field [0001] The invention relates to the technical field of disc spring assembly detection of a turbine shell bypass valve mechanism, in particular to a disc spring assembly detection device. Background technique [0002] When assembling the turbine casing bypass valve mechanism, the disk spring needs to be inserted into the mandrel, and the bottom and top of the disk spring need to be attached to the surfaces of the two parts of the rocker arm and the bush respectively; The following problems are prone to occur during the process, which increases the defective rate of the product: [0003] 1. Too many disc springs or missing ones; [0004] 2. The disc spring is installed reversely and skewed; [0005] 3. The disc spring is not inserted into the mandrel. Contents of the invention [0006] The object of the present invention is to propose a disc spring assembly detection device, which can determine whether the disc spring is assembled qualified by detecting th...
