Rail vehicle positioning joint press fitting device

Abstract

The invention discloses a rail vehicle positioning joint press fitting device which comprises a press fitting table. The press fitting table is arranged on a mobile trolley, the press fitting table isdriven by a lifting device to ascend and descend, and the press fitting table is provided with a positioning groove used for positioning a gland and a shaft box body, the two sides, corresponding tothe positioning groove, of the press fitting table are correspondingly provided with a vertical positioning column and a pushing press fitting device, and the pushing press fitting device comprises apushing rod and a first driving device for driving the pushing rod to press the positioning column. Compared with the prior art, the rail vehicle positioning joint press fitting device can conduct replacement and press fitting of positioning joints without lifting the shaft box body, direct replacement can be achieved even under the condition that the shaft box body is installed on a rail vehicle,the step of disassembling the shaft box body is omitted, a worker can conveniently operate the device, and the press fitting efficiency of the positioning joints is improved; and secondly, offset ofthe gland and a positioning rotary arm during the press fitting process can be avoided, pre-deflection stress cannot be generated after press fitting of the positioning joints, the press fitting effect is guaranteed, and the running of the rail vehicle is ensured.

Description

technical field [0001] The invention belongs to the field of rail vehicle assembly equipment, and in particular relates to a rail vehicle positioning node press-fitting device. Background technique [0002] At present, various types of rail vehicles usually use a positioning arm device to connect the wheel set and the bogie frame to transmit longitudinal force and certain lateral force, and provide elastic cushioning, so as to ensure the operation of the rail vehicle under various conditions. The installation of the positioning arm needs to press-fit the rubber positioning nodes to the axle box. The general process flow is to lift the axle box first, fix it on the installation platform, and then cover the gland and the rubber positioning nodes for pressing. Install and fix with bolts. However, the general press-fitting method can only carry out node press-fitting to the axle box body assembled on the wheel set, that is, after a period of operation on the rail vehicle, the p...

Problems solved by technology

However, the general press-fitting method can only carry out node press-fitting for the axle box body assembled on the wheel set, that is, when the rail vehicle has been running for a period of time, the positioning node wears out and needs to be replaced, the axle box body must be replaced first. It is unloaded from the rail vehicle, and then hoisted to the press-fitting platform to replace the positioning node. The disassembly process is complicated and the replacement steps are cumbersome, which makes the replacement and installation of the positioning node very inconvenient, and the press-fitting efficiency is low; secondly, in the press-fitting process At this time, the positioning of the gland and the axle box is not good enough, so there is a certain pre-deflection stress in the positioning node after pressing, and the pressing effect is not good, which affects the life of the positioning node and the running of the rail vehicle
