Abstract

The invention belongs to the technical field of machining and provides a boring tool for an axle suspension bush of a traction motor. The boring tool for the axle suspension bush of the traction motor comprises a working table (4), a movable tailstock I (1) and a movable tailstock II (2). The movable tailstock I (1) and the movable tailstock II (2) are matched with corresponding guide rails on the working table (4) respectively through slide blocks arranged on the bottoms of the movable tailstock I (1) and the movable tailstock II (2). A fixed center (5) used for being matched with a central hole in one end of a rotor shaft of the traction motor is installed on the movable tailstock I (1), and a movable center (6) used for being matched with a central hole in the other end of the rotor shaft of the traction motor is installed on the movable tailstock II (2). The boring tool achieves quick boring of the axle suspension bush of the traction motor under the condition of guaranteeing machining accuracy.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and mainly relates to a boring tool for a bearing bush of a traction motor. Background technique [0002] The traction motor is the main motor that drives the operation of electric locomotives, diesel locomotives, electric vehicles, industrial and mining locomotives, underground railway vehicles, urban trams and road vehicles. Its operating performance directly affects the traction performance and economic and technical indicators of rolling stock. on key equipment. [0003] Due to the large volume, large mass and high precision requirements of the traction motor, boring processing on a general-purpose boring machine has problems such as positioning and clamping processing difficulties. The most commonly used processing method is to use a special boring machine for boring processing, and make a Special processing equipment not only has a long manufacturing and debugging cycle, but ...
