Problems solved by technology

[0003] At present, a press-fitting device is generally used to directly press-fit the bushing of the drawbar seat to the side plate of the drawbar seat. During the press-fitting process, the phase between the bushing and the side plate is easy to change, resulting in the overall press-fitting accuracy of the drawbar seat. not tall

Abstract

The invention provides a positioning and guiding press-fitting device and a positioning and guiding press-fitting method for a draw bar seat. The device comprises a supporting and guiding part, a positioning and guiding part, a bracket and a positioning guide column. The supporting and guiding part comprises a supporting seat, and the supporting seat is arranged on the top of the supporting and guiding part in a liftable manner; the positioning guide column is fixedly arranged on the top of the supporting and guiding part, and the relative position between the positioning guide column and thesupporting seat and the relative position between an edge hole of the draw bar seat and a shaft sleeve are consistent; the bracket is fixedly arranged on the side face of the top of the supporting andguiding part, and the positioning and guiding part is arranged on the bracket; and the positioning and guiding part can move along the bracket in a height direction and corresponds to a position of apin hole of the shaft sleeve. According to the positioning and guiding press-fitting device and the positioning and guiding press-fitting method for the draw bar seat provided by the embodiment of the invention, the phase relation between the pin hole of the shaft sleeve and the edge hole of a side plate can be guaranteed when the shaft sleeve is press-fit into the shaft hole of the side plate, and meanwhile, the coaxiality of the edge holes of the two side plates can be guaranteed consistent.

Description

technical field [0001] The invention relates to the technical field of drawbar mounts, in particular to a positioning, guiding and press-fitting device and method for drawbar mounts. Background technique [0002] At present, high-speed maglev trains use a traction rod device to transmit traction force, and the traction rod device has a Z-shaped structure, including two traction rods and a draw rod seat between the two traction rods. Among them, when the traction rods on both sides are combined with the drawbar seat, the pin structure is adopted, so it is necessary to strictly ensure that the side plates on both sides of the drawbar seat are concentric with the two holes. When assembling, it is necessary to ensure that the threaded hole (pin hole) in the middle of the bushing of the drawbar seat and the two holes on the side plate of the drawbar seat maintain a strict phase relationship, so as to meet the assembly of the entire drawbar device. [0003] At present, a press-fi...
