Box body hole site detection tool

Abstract

The invention discloses a box body hole site detection tool which comprises a vertical plate and a hole plate. The hole plate is arranged on the vertical plate; the vertical plate can be erected on the box body to play a supporting role; the detection surface on the hole plate is placed on the end surface of the mounting base, the gap between the detection surface and the end surface is observed,the flatness of the end surface of the mounting base can be visually seen, and the detection mode is fast and reliable; the first positioning hole formed in the pore plate is matched with the second positioning hole formed in the mounting seat, and the positioning piece penetrates through the first positioning hole and the second positioning hole to fix the hole plate on the mounting seat, so thatthe detection hole can conveniently detect the position and specification of the mounting hole in the mounting seat; a positioning-first and detection-second manner is adopted, therefore, the hole plate is high in detection precision of the positions and specifications of the mounting holes, the detection tool is convenient to operate and suitable for large-scale popularization.

Description

technical field [0001] The invention relates to the technical field of inspection tools, in particular to a box hole location inspection tool. Background technique [0002] The installation of the main transformer of a locomotive needs to be suspended under the car body through the mounting bases at the four corners of the fuel tank. The hole position accuracy of the mounting holes on the mounting base and the surface flatness of the mounting base are directly related to whether the installation quality of the transformer meets the standard, such as If the pitch of the mounting holes is not correct, the locomotive main transformer and locomotive body cannot be installed, and the flatness of the mounting seat does not meet the requirements, which will cause a large assembly gap between the locomotive main transformer and the locomotive body, resulting in major mass ACCIDENT. [0003] At present, after the mounting seat and the mounting hole are processed, the commonly used d...

[0002] The installation of the main transformer of a locomotive needs to be suspended under the car body through the mounting bases at the four corners of the fuel tank. The hole position accuracy of the mounting holes on the mounting base and the surface flatness of the mounting base are directly related to whether the installation quality of the transformer meets the standard, such as If the pitch of the mounting holes is not correct, the locomotive main transformer and locomotive body cannot be installed, and the flatness of the mounting seat does not meet the requirements, which will cause a large assembly gap between the locomotive main transformer and the locomotive body, resulting in major mass ACCIDENT

[0003] At present, after the mounting seat and the mounting hole are processed, the commonly used detection methods are: 1. Use tape measure, caliper and flat ruler to detect, but the tape measure, caliper and flat ruler can only detect the flatness and installation of the two mounting seats on the same side of the fuel tank. The pitch of the holes; the flatness of the two mounts on the opposite side of the fuel tank and the pitch of the mounting holes, as well as the pitch between the mounting holes on the diagonal of the fuel tank and the flatness of the mounts cannot be detected; 2. Self-made fixation The hole distance ruler is used to detect the flatness of the mounting base and the hole distance of the installation hole. The self-made fixed hole distance ruler is inconvenient to operate, low in efficiency and prone to measurement errors, resulting in quality accidents
