Abstract

The invention relates to a side end positioning mechanism and a subway bogie automatic positioning and pressing device thereof, and the subway bogie automatic positioning and pressing device comprisesa positioning table used for installing and positioning a bogie; a side end positioning mechanism used for positioning and clamping two ends of the bogie; a pressing-down mechanism which is used forpressing down through a pressing-down plate to position the two ends of the bogie; and a medium-pressure module which is used for positioning the middle part of the bogie through downward pressing ofa medium-pressure plate. The positioning and pressing of the side faces of two ends, the two ends and the middle of the bogie can be achieved in a linkage mode, and meanwhile, the hoisting and positioning of the whole bogie are greatly facilitated through the movable design of a gantry. And the positioning table can realize the two-axis fine adjustment of the side end positioning mechanism, so that the initial positioning precision of the bogie is improved through the two-axis fine adjustment when the bogie is hoisted. And in addition, the pressing-down mechanism is mounted on the side end positioning mechanism, so that the precision of two-end side surface positioning and two-end pressing positioning can be ensured.

Description

technical field [0001] The invention relates to subway maintenance technology, in particular to an automatic positioning and pressing device for a subway bogie. Background technique [0002] In subway overhaul, overhauling the bogie is a necessary procedure. The current operation mode is to adopt the tooling to install the bogie, and then utilize the structure on the tooling to locate, compress or clamp the bogie. For bogies, it is generally necessary to perform centering positioning at both ends, pressing down positioning at both ends, and pressing down in the middle. After positioning through these positioning points, the position of the bogie can be relatively accurately determined, so as to provide future automation and intelligent maintenance. And provide the basis for disassembly. [0003] The current centering positioning of the tooling generally uses both ends to move synchronously for clamping, but due to the error factor of the bogie placement, there is a high pr...
