Description

Technical Field

[0001] The utility model belongs to the technical field of parts inspection, and in particular relates to a synchronous inspection tool for inner and outer mounting holes. Background Art

[0002] In existing motor accessory mesh inspection systems, each mesh specification corresponds to a specific inspection tool. This lacks versatility and requires frequent tool changes. The wide variety of tools also requires significant storage space, making maintenance time-consuming and labor-intensive. Furthermore, as specifications and models expand, the existing inspection tool no longer meets the dimensional requirements of some models.

[0003] For example, Chinese patent publication number CN209991900U addresses the existing problems of using conventional measuring tools to directly inspect workpiece dimensions, which are cumbersome, time-consuming, and have high rates of false positives and missed detections. Furthermore, the cost and inconvenience of using inspection devices for non-standard and custom parts are high. The patent provides a mounting hole inspection device, comprising an inspection module and a retrieval module. The inspection module includes a mainboard, which is provided with an outer circular inspection groove, a hole inspection cylinder, a tray groove, a positioning hole, and a weight-reducing hole. The hole inspection cylinder is centrally symmetrical, with a cylindrical lower portion and a conical upper portion. The retrieval module includes a retrieval tray and a retrieval rod, which are connected to the retrieval rod. The inspection module and the retrieval module are matingly connected. The inspection process is convenient, accurate, and quick, and the manufacturing cost is low and easy to implement, making it particularly suitable for inspecting non-standard or custom parts. However, Chinese patent publication number CN209991900U requires a separate inspection device for each accessory specification, which requires a large amount of storage space and is time-consuming and labor-intensive to maintain and repair.
