In another embodiment of the present application, the plunger 120 is integrally formed with the base 110.

The hole detection jig 100 provided by the embodiment, the inserted bar 120 and the base 110 are of an integrated structure, when detecting the piece to be detected 200, the top plate 111 and the bottom plate 113 can be attached to the corresponding surface 210 to be detected respectively, and meanwhile, the inserted bar 120 is tried to be inserted into the corresponding hole 220 to be detected, whether the hole pitch and the hole diameter of the hole 220 to be detected are standard or not is judged by observing whether the inserted bar 120 can be inserted into the corresponding hole 220 to be detected and whether the inserted bar can be attached to the corresponding hole wall of the hole 220 to be detected, and therefore, the detection efficiency of the hole diameter and the hole pitch is further improved.

The hole detection jig 100 provided in this embodiment can detect the to-be-detected piece 200 in two different ways, where the operation steps of the first way are as follows:

firstly, in a state that the inserting rod 120 is not installed on the base 110, the top plate 111 and the bottom plate 113 of the base 110 are respectively attached to the two surfaces 210 to be detected of the piece to be detected 200, if each through hole 114 on the base 110 can be approximately aligned with the corresponding hole 220 to be detected, it is indicated that the pitch and the diameter of the hole 220 to be detected on the piece to be detected 200 are approximately correct, otherwise, it is indicated that the pitch and/or the diameter of the piece to be detected 200 are deviated, by adopting the above operation, the pitch and the diameter of the piece to be detected 200 can be rapidly preliminarily determined, when the pitch or the diameter of the piece to be detected 200 are greatly deviated, problems can be rapidly found, and the detection efficiency is improved.

Then, after the hole pitch and the hole diameter of the to-be-detected piece 200 are preliminarily detected to be approximately correct, the inserted link 120 passes through the through hole 114 of the base 110 and is inserted into the corresponding to-be-detected hole 220, if the inserted link 120 cannot be inserted into the corresponding to-be-detected hole 220, the hole diameter of the to-be-detected hole 220 is relatively small, if the inserted link 120 can be inserted into the corresponding to-be-detected hole 220, but the inserted link 120 can move in the radial direction in the corresponding to-be-detected hole 220, the hole diameter of the to-be-detected hole 220 is relatively large, and if the inserted link 120 can be inserted into the corresponding to-be-detected hole 220 and is attached to the hole wall of the corresponding to-be-detected hole 220, the hole diameter of the to-be-detected plate is qualified; on the basis that the aperture of each hole 220 to be detected is qualified, if the two holes 220 to be detected cannot be inserted into the inserted link 120 at the same time, it indicates that the pitch between the two holes 220 to be detected is deviated, and if the two holes 220 to be detected can be inserted into the inserted link 120 at the same time, it indicates that the pitch between the two holes 220 to be detected is correct, so that further accurate detection of the pitch and the aperture of the piece 200 to be detected can be realized.

The second mode of operation comprises the following steps: after all the insertion rods 120 are installed in the corresponding through holes 114, the detection of the to-be-detected piece 200 is performed by using the insertion rods 120 and the base 110 connected into a whole, and the operation steps of the detection refer to the operation steps when the insertion rods 120 and the base 110 are integrally formed, which are not described herein again.

In another embodiment of the present application, referring to fig. 1 and 3, the outer contours of the bottom plate 113 and the top plate 111 are respectively consistent with the outer contour of the corresponding surface 210 to be detected. In this way, in the detection process, the outer contour of the bottom plate 113 is aligned with the outer contour of the corresponding surface 210 to be detected, and the outer contour of the top plate 111 is aligned with the outer contour of the corresponding surface 210 to be detected, so that the through hole 114 on the base 110 can be quickly aligned with the corresponding hole 220 to be detected, and the detection efficiency is improved.
