Description

Technical Field

[0001] This utility model belongs to the field of locomotive maintenance, specifically relating to a tooling fixture for repairing the side wall louvers of HXD1 locomotives. Background Technology

[0002] The HXD1 series locomotive sidewall louvers consist of a filter body comprised of an air guide grille, dust collection grille one, and dust collection grille two, along with a frame and sealing strip. They are bolted to the locomotive sidewall through four mounting holes. The filter body and frame of the louvers are both made of aluminum profiles and welded together as a single unit; they cannot be disassembled.

[0003] During use, if cracks, deformations, or dents occur in the side wall louvers, mechanical straightening can be used to restore their flatness when the side strips of the side wall louvers are deformed. However, there is no effective repair process for cracks in the louver welds or dents and protrusions in the rainproof grilles of the transition area. Usually, the entire set of side wall louvers is replaced. However, the side wall louvers of Harmony locomotives are expensive, resulting in high replacement costs.

[0004] To reduce production costs, theoretical research suggests that sidewall louvers can be repaired by replacing the air guide grille or dust collection grille. However, in practice, replacing the air guide grille or dust collection grille requires drilling holes in the upper surface of the sidewall louvers. This necessitates fixing the sidewall louvers in place. Since the sidewall louvers are made of aluminum profiles, excessive force when clamping them can easily cause cracking, deformation, or dents. Insufficient force makes drilling impossible during the repair process. Utility Model Content

A clamping plate is provided on the vertical rod. One end of the clamping plate is slidably connected to the vertical rod, and a drilling device is installed on the other end of the clamping plate.

[0007] The left side plate has a mounting hole A at the upper end, and the left end of the guide rail is inserted into the mounting hole A; the mounting hole B is located below the mounting hole A. The mounting hole B is a horizontal threaded through hole, and a left positioning rod passes through the mounting hole B; the mounting hole C is located below the mounting hole B.

Below the mounting hole D, there is a mounting hole E, which is a horizontal threaded through hole, and a right positioning rod passes through the mounting hole E. Below the mounting hole E, there is a mounting hole F, which is located on the left end of the right side plate.
