The invention provides a top plate framework positioning tool, and relates to the technical field of vehicle top plate installation. The top plate framework positioning tool comprises a base, a supporting column, a bearing frame, first sliding pieces and a second sliding piece, and the supporting column is arranged on the base; the bearing frame is arranged at the upper end of the supporting column; the first sliding piece is connected to the bearing frame in a sliding mode in the horizontal direction and used for bearing and positioning a longitudinal beam of a top plate framework; and the second sliding piece is connected to the bearing frame in a sliding mode and used for bearing and positioning a cross beam of the top plate framework. According to the top plate framework positioning tool, the supporting columns on the base are used for supporting the bearing frame, the first sliding pieces arranged on the bearing frame can bear the longitudinal beam of the top plate framework, the second sliding piece can bear the cross beam of the top plate framework, the top plate framework positioning tool is suitable for the positioning requirements of top plate frameworks of different specifications, the position of the base can be adjusted according to a positioning mark on a floor, then effective positioning of the top plate framework is achieved, the installation efficiency is effectively improved, and the installation precision of the top plate framework is guaranteed.
Description
technical field [0001] The invention belongs to the technical field of vehicle roof installation, and more specifically relates to a roof frame positioning tool. Background technique [0002] The outer contour of the roof frame of the crew room of the EMU (referred to as the roof frame) is semicircular, and the interior of the roof frame is distributed with criss-cross longitudinal beams and beams. The positioning and installation of the roof frame is the most important step in the installation of the cabin, which affects the connection and installation of other components. The tools needed for the positioning and installation of the existing roof frame include a laser marking instrument, a spirit level, a support rod, a box ruler, and the like. When positioning, first mark the reference point on the roof frame, then set the laser marking instrument at the preset point on the car body floor, manually lift the roof frame, and align the roof frame according to the beam positi...
