Description

Technical Field

[0001] The utility model belongs to the field of mechanical engineering, and in particular relates to a welding tool for a driver's cab door frame mounting seat. Background Art

[0002] Urban rail transit is aimed at transporting passengers quickly and in large quantities. The driver's cab door, which is the driver's access channel, also plays an important role in the operation of the vehicle. The driver's cab door frame has been widely used in subway vehicles, but it also has disadvantages such as complex structure, difficult installation, and poor door opening and closing performance. Therefore, the driver's cab door frame mounting seat, as the driver's cab door slide rail platform, has particularly strict requirements on flatness. In addition, since the production of subway vehicles started late in China, the theoretical analysis and process optimization of non-major components such as the passenger compartment door system of subway vehicles are insufficient, and the driver's cab door frame is not well-designed. The door frame mounting seat, as a part of the driver's cab door frame, is mainly responsible for the subsequent installation of the car door, so the overall flatness of the mounting seat is crucial; since there are four mounting seats, three of which are on the upper cover plate assembly and one is attached to the rear door column assembly, and there is one on the end corner column, due to welding deformation caused by assembly and welding of the driver's cab, it is impossible to ensure that the upper cover plate assembly, the rear door column assembly, and the end corner column reach the theoretical contour. In order to overcome the shortcoming of the overall flatness of the driver's cab door frame mounting seat in the prior art that it is easy to exceed the tolerance, it is necessary to provide a welding tool to control the overall flatness of the mounting seat and improve the installation efficiency of the mounting seat. Utility Model Content

[0003] The technical problem to be solved by the utility model is that the overall flatness of the driver's cab door frame mounting seat in the prior art is prone to exceed the tolerance.

[0004] In order to solve the above technical problems, a technical solution provided by the utility model is:

[0005] A driver's cab door frame mounting seat assembly welding tool comprises a positioning plate assembly, wherein the positioning plate assembly comprises a first-side positioning plate and a second-side positioning plate, and the structure of the first-side positioning plate is symmetrical to the structure of the second-side positioning plate.

[0032] Embodiment: A driver's cab door frame mounting seat assembly welding tool includes a first-side positioning plate and a second-side positioning plate. The structure of the first-side positioning plate is symmetrical to that of the second-side positioning plate. When in use, the first-side positioning plate and the second-side positioning plate are used together. The first-side positioning plate is used for the positioning and assembly welding of the mounting seat on the upper side of the driver's cab door frame on the first side, and the second-side positioning plate is used for the positioning and assembly welding of the mounting seat on the upper side of the driver's cab door frame on the second side.

[0033] The first side locating plate and the second side locating plate are both made of 16mm thick aluminum plate. The overall flatness of the first side locating plate and the second side locating plate is less than 1mm, to ensure that the mounting seats installed on the first positioning groove 3, the second positioning groove 4, the third positioning groove 5 and the fourth positioning groove 6 are on the same plane during assembly, thereby effectively ensuring the overall flatness of the driver's cab door frame mounting seat.

[0034] A side positioning plate includes a first positioning plate 1 and a second positioning plate 2. The first positioning plate 1 is a straight bar type positioning plate. The first positioning plate 1 is provided with a left positioning groove and a right positioning groove with one end open.

[0043] When in use, first adjust the overall flatness of the first side positioning plate and the second side positioning plate to make their flatness less than 1mm, paste three layers of cloth-based tape on the back of the third positioning groove 5, and use M8×45 bolts to fix the corresponding mounting seats on the first positioning groove 3, the second positioning groove 4, the third positioning groove 5 and the fourth positioning groove 6, and then fit the positioning wall 15 on the first side positioning plate or the second side positioning plate with the upper side or lower side of the door frame slide groove, position the first side positioning plate and the second side positioning plate, and then align the mounting seat on the first positioning groove 3 through the first positioning notch 7 and the second positioning notch 8. Perform positioning welding, position welding the mounting seat on the second positioning groove 4 through the second positioning notch 8 and the third positioning notch 9, position welding the mounting seat on the third positioning groove 5 through the third positioning notch 9, the first positioning angle 11 and the second positioning angle 12, and position welding the mounting seat on the fourth positioning groove 6 through the fourth positioning notch 10. After positioning welding of all mounting seats, remove the bolts, remove the first side positioning plate or the second side positioning plate, and then weld the complete mounting seat. After installation welding, the overall flatness requirements are basically met. The overall structure is simple, the operation is convenient and flexible, and the overall flatness of the driver's cab door frame mounting seat can be effectively guaranteed.
