Description

Technical Field

[0001] The present invention relates to the technical field of overall flatness control of rail vehicles, and in particular to a pairing device for controlling the overall flatness of a subway vehicle doorway. Background Art

[0002] The Los Angeles Metro project represents our company's flagship product for the high-end export market, requiring high standards for the overall vehicle appearance. This project demands exceptionally high vehicle strength, with numerous welds densely packed between the underside of the door columns and the underframe, and numerous long fillet welds on the reinforcement plates between the door columns and the upper crossbeam. The door mechanism for this project differs significantly from that of typical domestic vehicles, placing significantly higher demands on the overall flatness of the door area. Since previous projects did not require individual control of the overall flatness of the door area, using traditional welding methods resulted in the metro project failing to achieve the 3mm flatness tolerance required for door mechanism installation.

[0003] Therefore, it is urgent to provide a device that can control the overall flatness of the doorway area separately. Summary of the Invention

[0004] The purpose of the present invention is to provide a device for controlling the overall flatness of a subway vehicle door, so as to meet the requirement that the overall flatness of the vehicle door area does not exceed 3mm.

[0008] Two upper horizontal tie rods are arranged in parallel and are both detachably connected to the upper parts of the two frames. The two upper horizontal tie rods are used to adjust the relative distance between the two frames in the width direction.

[0009] Multiple flip clamps are divided into two groups, one end of each group of flip clamps is fixedly connected to the lower part of the same frame, each flip clamp is provided with a mutually perpendicular vehicle body width direction positioning surface B and a vehicle body height direction positioning surface C, the vehicle body height direction positioning surface C is located on the bottom surface of the frame, the vehicle body width direction positioning surfaces B of multiple flip clamps in the same group are coplanar, and the vehicle body height direction positioning surfaces C of multiple flip clamps in the same group are coplanar. The flip clamps are used to tightly fit the lower planes of the two frames with the upper plane of the vehicle underframe side beam when tightening;

[0010] Two lower horizontal pull rods are arranged in parallel, and both are detachably connected to the lower parts of the two frames, and the two lower horizontal pull rods are used for tightly attaching the body width direction positioning surfaces B of the plurality of turnover compactors below the two frames to the vehicle side wall outer wall plates;

[0011] Two diagonal pull rods are arranged in cross, and both are detachably connected to the side parts of the two frames, and the two diagonal pull rods are used for adjusting the diagonal line difference of the two frames so that the two frames are in a vertical state.

The four hanging seats 7 are symmetrically fixed on the upper part of the two frames 1, and the four hanging seats 7 are used to hoist the group pair device. The two upper horizontal pull rods 2, the two lower horizontal pull rods 3 and the two inclined pull rods 4 are all length-adjustable pull rods.

[0022] The two frames 1 are arranged in parallel, and each frame 1 is provided with three door flatness positioning surfaces A on both sides. The six door flatness positioning surfaces A on the same frame 1 are machined as a whole, and the overall flatness is less than 0.5mm.

[0023] The two upper horizontal pull rods 2 are arranged in parallel and are detachably connected to the upper part of the two frames 1. The two upper horizontal pull rods 2 are used to adjust the relative distance of the two frames 1 in the width direction.

[0024] The four turnover compressors 6 are divided into two groups. One end of each group of turnover compressors 6 is fixed to the lower part of the same frame 1. Each turnover compressor 6 is provided with a vehicle width direction positioning surface B and a vehicle height direction positioning surface C which are perpendicular to each other. The vehicle height direction positioning surface C is located on the lower bottom surface of the frame 1. The vehicle width direction positioning surfaces B of the two turnover compressors 6 in the same group are coplanar. The vehicle height direction positioning surfaces C of the two turnover compressors 6 in the same group are coplanar. The turnover compressor 6 is used to tightly fasten the lower plane of the two frames 1 to the upper plane of the vehicle chassis side beam when it is rotated.

[0025] The two lower horizontal pull rods 3 are arranged in parallel and are detachably connected to the lower part of the two frames 1. The two lower horizontal pull rods 3 are used to tightly fasten the vehicle width direction positioning surfaces B of the four turnover compressors 6 below the two frames 1 to the vehicle side wall outer wall plate.

[0026] The two inclined pull rods 4 are arranged in cross and are detachably connected to the side part of the two frames 1. The two inclined pull rods 4 are used to adjust the diagonal line difference of the two frames 1, so that the two frames 1 are in a vertical state.

[0027] The twelve positioning surface compressors 5 are detachably connected to the frame 1 and are arranged opposite to the twelve door flatness positioning surfaces A one by one. The twelve positioning surface compressors 5 are used to tightly fasten the twelve door flatness positioning surfaces A to the two sides of the vehicle door, so as to ensure that the change amount of the overall flatness of the vehicle door area before and after welding meets the overall flatness requirement of the vehicle door.

[0028] The application is used for controlling the whole flatness of the subway vehicle door, first, all the positioning surface compressors 5 are detached from the two frames 1, the length of all the horizontal pull rods and the inclined pull rods is adjusted according to the distance between the two doors, then the whole door flatness positioning surface A of the two frames 1 is respectively pasted on the two sides of the vehicle door wall, the vehicle height direction positioning surface C is placed on the upper plane of the vehicle chassis side beam, and the vehicle width direction positioning surface B is pasted on the outer wall plate of the vehicle side wall; then all the positioning surface compressors 5 are installed on the two frames 1 one by one, all the positioning surface compressors 5 are locked, all the turnover compressors 6 are locked, so that the whole door flatness positioning surface A is tightly pasted on the two sides of the vehicle door, the lower plane of the two frames 1 is tightly pasted on the upper plane of the vehicle chassis side beam, and the vehicle width direction positioning surface B is tightly pasted on the outer wall plate of the vehicle side wall, and then the subsequent assembly and welding process can be carried out. In the welding process, the assembly device for controlling the whole flatness of the subway vehicle door can effectively control the whole flatness of the vehicle door area within 3mm.
