Abstract

The invention provides a locomotive hollow shaft rubber joint press-mounting method. A rotary mandrel is arranged on a platform surface of a work platform, and positioning pin bases, pressing plate bases and press-mounting mechanical devices are arranged on the platform surface and the platform side according to distribution angles of rubber joint installation holes in a hollow shaft. The large-end hole of the hollow shaft is formed in the rotary mandrel, the hollow shaft is rotated so that after one installation hole is aligned to one positioning pin base, one positioning pin is inserted into the corresponding installation hole and clamp a pressing plate on the corresponding pressing plate base, and the installation hole at the corresponding angle is located in the station of the corresponding press-mounting mechanical device. Then press-mounting is carried out on a rubber joint by means of the press-mounting mechanical devices. Positioning and aligning are accurate, operations are easy, what is needed is poking and rotating, manual transportation for adjustment is needless, tools are needless to be adjusted, labor intensity is low, one worker can operate, work efficiency is improved by three times, and press-mounting quality is effectively guaranteed.

Description

technical field [0001] The invention relates to a method for press-fitting a rubber joint of a locomotive hollow shaft, belonging to the technical field of railway locomotive manufacturing. Background technique [0002] The hollow shaft is the key part of the driving device of the locomotive bogie. Six rubber joints are press-fitted on each hollow shaft. Flip and flatten. In the prior art, the following methods are used to press-fit rubber joints to the hollow shaft: [0003] press fit. Based on the three-claw disk surface of the hollow shaft, place the hollow shaft on the platform, manually adjust the position of the rubber joint hole for the hollow shaft, so that it is exposed outside the platform, a hydraulic cylinder is installed at the bottom of the support frame, and a tray is installed on the top of the hydraulic cylinder , the rubber joint is placed in the tray, and the clamping disc is installed on the upper part of the supporting frame. ) Alignment to ensure th...
