Since the window frame of the carriage is not composed of a whole frame, it is usually composed of three parts: the side wall, the column and the roof of the carriage, the integrated assembly of the carriage and the deformation of the carriage during the long-term operation of the train are easy to cause The hole positions of the mounting holes are deviated, so that the mounting holes cannot be aligned with the mounting holes on the frame of the side window glass, and the only way to fix the frame of the side window glass and the window frame of the compartment is to use reaming; however, the method of reaming on site seriously affects Installation efficiency and installation quality of side window glass
[0004] In addition, when replacing the side window glass, due to the smooth surface and heavy weight of the side window glass embedded in the side window glass frame, it is often necessary to use suction cup tools and the assistance of multiple people to complete the handling of the side window glass; and when replacing the side window glass Also need the staff to carry out climbing operations to complete the installation of side window glass
If the method of on-site reaming is adopted, in order to ensure the alignment of the mounting hole and the assembly hole, repeated disassembly and assembly calibration must be carried out, which is very prone to safety accidents such as side window glass falling and staff being injured

Abstract
The invention discloses a side window glass frame installation hole positioning device and a using method. The side window glass frame installation hole positioning device comprises a positioning frame and multiple drilling bush assemblies. The positioning frame is aligned with a carriage window frame provided with a plurality of assembly holes and a side window glass frame which is not drilled. Each drill bushing assembly is connected with the positioning frame and is used for marking the hole position of the corresponding assembly hole so as to conduct installation hole positioning on the side window glass frame. The positioning frame can be aligned with the carriage window frame, the hole positions of the assembly holes in the carriage window frame are marked through the drill bushing assemblies, then the positioning frame is aligned with the side glass frame which is not drilled, and the side glass frame can be subjected to installation hole positioning according to the hole positions of the assembly holes marked by the drill bushing assemblies. The positioning precision and the positioning efficiency of installation holes of the side window glass frame are effectively improved, and then the replacement efficiency and the installation quality of side-mounted glass are improved.
Description
technical field [0001] The invention relates to the technical field of side window glass frame processing, in particular to a side window glass frame mounting hole positioning device for a maglev train and a use method thereof. Background technique [0002] There are generally 12 to 14 pieces of side window glass on both sides of each car of the maglev train; the side window glass is a hollow sandwich structure, which has good sound insulation, heat insulation and light transmission effects. However, after the maglev train has been running for a period of time, some side window glass will leak air, causing moisture to enter the hollow interlayer of the side window glass, causing the inner surface of the side window glass to gradually condense and turn white, and the transparency is greatly reduced, affecting the appearance of the train experience with passengers; in addition, during the operation of the maglev train, the external impact of birds or stones will also cause the...
