The detecting tool and the detecting method have the following defects:

1. the existing detection mode has low detection efficiency, and the position degree of the part can be obtained only by 2 steps of detection.

2. In the detection process, the excircle of the detection tool base, the V-shaped block, the core rod and the positioning rod need to be tightly attached, if the excircle is not tightly attached, the position detection value is inaccurate.

3. The position degree is needed to be obtained through reading the numerical value and calculating, and then is checked with the required value, so that errors are easy to generate.

The aim of the utility model is achieved by the following technical scheme. The utility model provides a pinhole position degree examines utensil, includes examines a main part, is equipped with the positioning cylinder at examining a main part central point put, and the positioning cylinder is used for with the central hole matching connection of fork, and the both sides are equipped with position degree groove A and position degree groove B respectively about the positioning cylinder, and position degree groove A and position degree groove B are used for with pass the plug matching connection of pinhole.

Furthermore, the gauge main body comprises a bottom plate, a left baffle plate and a right baffle plate, and a positioning cylinder is arranged in the center of the bottom plate; the left baffle and the right baffle are respectively arranged at the left side and the right side of the positioning cylinder, the left baffle is provided with a position degree groove A, and the right baffle is provided with a position degree groove B.

Further, the bottom plate, the left baffle plate and the right baffle plate are of an integrated structure.

Furthermore, the position degree groove A and the position degree groove B are upwards-opened linear grooves, and the position degree groove A and the position degree groove B are coaxial and are matched with the central line of the positioning cylinder in position.

The beneficial effects of the utility model are as follows:

1. the special gauge for the pin hole position degree with the new structure is designed, the coincidence of the pin hole position degree can be directly clamped once through the special gauge, and the detection efficiency is improved.

2. Auxiliary fixtures such as gauge base, V type, locating lever are cancelled, cancel the deviation influence to the testing result.

3. The position degree is directly detected to obtain the pass or fail without reading and calculating.
