In addition, the size of the rear floor is large, and many pin holes that need to be detected are located in the center of the part. It is cumbersome for workers to detect the pin hole positions in the central area of ​​the rear floor. Utility Model Content

[0004] In order to solve the above problems, the utility model provides an assembly inspection tool which can quickly detect the position of the pin hole of the rear floor of an automobile.

[0005] The utility model solves the technical problem by adopting the following technical scheme: a rear floor inspection tool with interchangeable inspection pins, comprising a workbench and a positioning assembly, a fixing assembly and a plurality of inspection assemblies installed on the workbench, wherein the positioning assembly is used to place the rear floor of the automobile to be inspected, the fixing assembly is arranged around the positioning assembly, and the fixing assembly is used to press and fix the rear floor of the automobile to be inspected on the positioning assembly; the inspection assembly is used to inspect the pin hole position of the rear floor of the automobile to be inspected, each of the inspection assemblies comprises an inspection left column, an inspection right column, an inspection beam and a plurality of rear floor inspection blocks, the inspection left column and the inspection right column are respectively arranged on the left and right sides of the positioning assembly, the two ends of the inspection beam are respectively detachably connected to the inspection left column and the inspection right column, the front side surface and / or the rear side surface of the inspection beam are provided with a groove body arranged in the left and right directions, each of the rear floor inspection blocks comprises a connecting plate and an inspection plate connected to each other, the connecting plate is installed on the groove body through a slider, and a bolt inspection pin and a bolt marking pin are provided on the inspection plate. When in use, install the corresponding rear floor inspection block on the corresponding position of the inspection beam according to the design standard, and then fix the inspection beam above the rear floor of the vehicle to be inspected through the left inspection seat and the right inspection seat. By comparing the matching degree of the bolt inspection pins and the bolt marking pins on the inspection plate with the rear floor of the vehicle to be inspected, it can be determined whether the rear floor of the vehicle to be inspected is qualified.

[0006] Furthermore, the inspection beam is made of aluminum alloy profile, which is light and easy to produce. The cross section of the trough body is in an inverted "T" shape, which is convenient for the installation of the slider. The connecting plate can also be provided with a fastening screw to facilitate fixing the position of the rear floor detection block on the inspection beam.

[0007] Furthermore, two handles are installed on the upper end surface of the inspection beam to facilitate holding, installation and replacement.

[0008] The beneficial effect of the utility model is that the inspection component adopts a crossbeam as a carrier for bolt detection pins and bolt marking pins, which facilitates the inspection of various elements in the central area of ​​large-size parts, and unifies the introduction section specifications of bolt detection pins and bolt marking pins, reduces the types of pins, and increases versatility.
