Traction motor node press-mounting and withdrawing machine

Abstract

The invention relates to a traction motor node press-mounting and withdrawing machine which comprises an electronic control and hydraulic system and is provided with a working table. A box-shaped support is arranged on the working table; a lifting device and telescopic devices are arranged on the box-shaped support; the telescopic devices are characterized in that concave forks are arranged in front of flat plates; the two telescopic devices are symmetrically arranged on the left side and the right side of the box-shaped support; transition plates are connected to the inner sides of the left and right flat plates; a connecting plate is arranged in the rears of the left and right transition plates and is connected with a nut connecting block; the nut connecting block is matched with a screwrod of the lifting device; guide rails and guide slots A for cooperation are arranged between the flat plates and the transition plates; guide rails and guide slots B for cooperation are arranged ontwo sides of the transition plates and the box-shaped support; guide rails and guide slots C for cooperation are arranged between the working table and the box-shaped support; oil cylinders and standstill locking blocks are arranged in the concave forks; a traction motor placement table is arranged right ahead of the working table; and a positioning bolt point and a positioning block are arrangedin the rear of the placement plate. The machine can mechanically accomplish press-mounting or withdrawing of a motor node, so that time and effort are saved, a workpiece cannot be damaged, and technology and market vacancies are filled.

Description

technical field [0001] The invention relates to a rail transit equipment machine, in particular to a press-fitting and unloading machine for traction motor nodes of CRH series EMUs. Background technique [0002] It is understood that currently there is no professional machinery for the press-fitting or unloading of the traction motor nodes of the CRH series EMUs. The press-fitting or unloading is done by manual operation, which is not only time-consuming and laborious, but also damages the traction motor during the press-fitting process. Aperture, lifting lugs, workbench strength is not enough and so on. Contents of the invention [0003] In order to solve the problem of insufficient existing technology, the present invention provides a traction motor node press-fitting and unloading machine, which has a simple structure, can mechanize press-fitting or unloading, saves time and effort, and does not damage the workpiece. [0004] In order to achieve the above object, the t...
