Abstract

A positioning platform and its subway bogie automatic positioning and pressing device, the subway bogie automatic positioning and pressing device includes: a positioning platform for installing and positioning the bogie; a side positioning mechanism for positioning and clamping the bogie Both ends; the lower pressing mechanism is used to press down and position the two ends of the bogie through the lower pressure plate; the medium pressure module is used to press down and position the middle part of the bogie through the middle pressure plate. The present invention can realize positioning and compaction of the sides of both ends of the bogie, pressing down at both ends, and pressing down in the middle through linkage, and at the same time, the hoisting and positioning of the whole bogie is greatly facilitated by the movable design of the gantry. Moreover, the positioning platform of the present invention can realize the two-axis fine adjustment of the side end positioning mechanism, so that the initial positioning accuracy of the bogie can be increased through the two-axis fine adjustment when hoisting the bogie. In addition, installing the pressing mechanism on the side end positioning mechanism can ensure the accuracy of the side positioning at both ends and the pressing positioning at both ends.

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...
