[0034] Reference below Figure 1-Figure 7 The apparatus 100 for detecting the hole groove depth according to the embodiment of the present invention is described.

[0035] The hole depth detection device 100 of the embodiment of the present invention comprises a base 1 , a measuring reset member 2 , a measuring gauge 3 and a clamping member 4 .

[0036] The measurement reset member 2 is disposed on the base 1, and the measurement reset member 2 is relative to the base 1 along a first preset direction (for example, Figure 1 The measuring table 3 is arranged on the measuring reset member 2, and the measuring table 3 is movable along the second preset direction (for example, Figure 1 The front-to-rear direction shown in FIG) is movably arranged on the measurement reset member 2, and the second preset direction is arranged perpendicular to the first preset direction.

[0037] The hole and slot depth detection device 100 of the embodiment of the present invention, by setting the measuring gauge 3 on the measuring reset member 2, can drive the measuring gauge 3 to move along the first preset direction through the measuring reset member 2. Therefore, it can be applicable to measuring holes with different hole depths. At the same time, by driving the measuring gauge 3 to move along the first preset direction through the measuring reset member 2, automatic reset can be achieved. Therefore, the hole and slot depth detection device 100 has the advantages of convenient operation and good applicability.

[0038] In addition, the hole depth detection device 100 of the embodiment of the present invention is movably arranged on the measurement reset member 2 along the second preset direction through the measuring table 3, and can measure the measurement holes at different positions.

[0042] The hole depth detection device 100 of the embodiment of the present invention is configured by dividing the measuring reset member 2 into a reset frame 21 and a guide rail 22 , and the guide rail 22 is movably mounted on the reset frame 21 .

[0043] For example, when there is a deviation between the detection hole and the measuring table 3 in the front-to-back direction, the measuring table 3 can be moved to make the measuring table 3 correspond to the measuring hole in the front-to-back direction.
