[0016] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. Example

[0017] The utility model provides a gauge for the end face and guard plate surface of the starter housing assembly. The gauge is an integrally processed tooling, circular in shape, and hollow inside. The circular structure is divided into four sections. The first section is a cylindrical surface serving as the bottom surface of the gauge, with an inner diameter adapted to the outer diameter of the housing assembly; the second section is an inclined surface consistent with the inclined surface of the housing assembly; the third section is a cylindrical surface, with an inner diameter adapted to the outer diameter of the upper end of the housing assembly guard plate; the fourth section is a cylindrical top surface serving as the gauge press-fitting surface, with an inner diameter dimension processed according to actual needs (e.g., ∅138mm) to meet the requirements of assembly, weight reduction, and observation.

[0018] The utility model has a hollow structure as a whole, which is convenient for assembly and reduces the weight of the checking tool.

[0019] The inner diameter of the first cylindrical surface is consistent with the outer diameter ∅190mm of the shell assembly, which facilitates dimensional inspection of the outer diameter ∅190mm of the shell assembly.

[0020] The second section of the inclined surface facilitates the inspection of the outer dimensions of the shell component guard plate.

[0021] The inner diameter of the third cylindrical surface is consistent with the outer diameter ∅159mm of the upper end of the shell component guard plate, which facilitates the dimensional inspection of the outer diameter of the upper end of the shell component guard plate.

[0022] The third and fourth sections of the inspection fixture are provided with two symmetrical grooves, which facilitate direct observation and marking of high points on the surface of the shell component guard plate, and lock the fault position on the surface of the shell component guard plate for subsequent fault handling.

[0023] During assembly and inspection of the starter housing assembly, the first cylindrical surface 1 is used to position the fixture, ensuring that the bottom surface 2 is effectively aligned with the starter housing assembly without causing damage. Pressure is then applied via the press-fit surface 3 to secure the assembly in place, ensuring safe and reliable assembly. After the starter housing assembly is assembled, the high points on the housing assembly's shielding plate can be directly observed and marked using the groove 4.
