AI Technical Summary

Technical Problem

Existing technologies cannot achieve high precision in detecting the depth of inclined grooves by calculating the included angle between the sealing groove and the edge plate surface, resulting in insufficient detection accuracy.

Method used

A groove depth detection device is adopted, including a base, a rotating seat, a measuring pin, and a connecting pin. The displacement of the measuring pin and the connecting pin is made symmetrical through a synchronization mechanism. The displacement of the connecting pin can be directly measured as the groove depth. Automatic reset is achieved by combining a cam and a torsion spring, which facilitates high-precision detection.

Benefits of technology

It improves the accuracy of sloping groove depth detection, simplifies the detection process, reduces conversion steps, and enhances the convenience and accuracy of detection.

Abstract

The application discloses a chute depth detection device, which comprises a base, a positioning reference surface and a detection reference surface arranged on the base and parallel to each other, a rotating seat arranged in the base and rotationally matched with the base, a rotating center line of the rotating seat being perpendicular to the positioning reference surface, a measuring pin slidably matched with the rotating seat in a direction perpendicular to the rotating center line of the rotating seat and extending from the positioning reference surface to be inserted into the chute, a switching pin parallel to the measuring pin and slidably matched with the rotating seat in the direction perpendicular to the rotating center line of the rotating seat and extending from the detection reference surface, and a synchronous mechanism arranged on the rotating seat and used for synchronously moving the measuring pin and the switching pin so that the displacement of the measuring pin and the switching pin is symmetrical about the rotating center line of the rotating seat. The application only needs to use a detection instrument to detect the distance of the switching pin relative to the detection reference surface, which is equivalent to the depth of the chute, the displacement of the switching pin is directly measured, conversion is not needed, and the detection precision is high.
