[0002] Threaded holes need to be opened in the bearing cover during production. After the threaded holes are opened, they need to be inspected. The no-go gauge and the through gauge are important parameters for threaded hole inspection. If the through gauge head can be smoothly screwed into the threaded hole, it means that the through gauge of the threaded hole is qualified, otherwise it is unqualified; if the no-go gauge head can be screwed into the threaded hole for more than 2 turns, it means that the no-go gauge of the threaded hole is unqualified, otherwise it is qualified.

[0028] In this embodiment, the connector 19 is a connecting sleeve, the upper end of which is sleeved on the output shaft of the driving motor 17 and locked by bolts, and the lower end of which is used to install the stop gauge detection head 20 or the through gauge detection head. Further, the upper end of the stop gauge detection head 20 is inserted into the connecting sleeve and locked by bolts, and the upper end of the through gauge detection head is inserted into the connecting sleeve and locked by bolts.

[0029] In this embodiment, in order to facilitate the identification of whether the no-gauge detection and the through-gauge detection meet the standards, a contact switch 22 corresponding to each connecting sleeve is installed on the vertical plate 7. If the connecting sleeve with the no-gauge detection head 20 installed does not touch the contact switch 22, it reflects that the no-gauge detection meets the standards; if the connecting sleeve with the through-gauge detection head installed touches the contact switch 22, it reflects that the through-gauge detection meets the standards.

[0030] In this embodiment, the clamping and positioning mechanism includes a clamping assembly and an intercepting assembly.
