Abstract

The invention belongs to the field of machining detection and precision measurement, and in particular relates to a tool for detecting the position and size of holes on the surface of parts, including a diameter scale, a measuring component and a positioning component. One end of the diameter scale is fixed with a fixed base, and the other end of the sliding sleeve is provided with a movable The base, the main vernier slides on the diameter scale, and the measurement component is fixed at the bottom of the main vernier; the measurement component includes an angle plate, an angle measurement plate and a secondary measuring ruler. The angle plate is fixed on the main vernier, and the angle measurement plate is rotated on the angle plate On the top, the auxiliary measuring ruler is fixed on the angle measuring disk, the auxiliary measuring ruler is perpendicular to the axis of the angle disk, the auxiliary measuring ruler is slid to set the auxiliary vernier, and the bottom of the auxiliary vernier is fixed with a positioning assembly; the positioning assembly includes one end set on the auxiliary vernier The positioning rod is provided with a plurality of measuring rods, the plurality of measuring rods form an umbrella-shaped structure that is folded toward the measuring plane, and the positioning rod is parallel to the axis of the angle plate.

Description

technical field [0001] The invention belongs to the field of machining detection and precision measurement, in particular to a tool for detecting the position and size of holes on the surface of parts. Background technique [0002] Opening holes on the surface of parts is a common processing method in the field of mechanical processing, and due to actual functional requirements, the hole position and size of surface parts must be designed accurately and reasonably. If you use a vernier caliper and other tools for measurement, first, you cannot accurately measure the center of the hole. In this measurement process, it is always a local size measurement rather than an overall positioning measurement. The error of the result is relatively large, and the results are often due to It is difficult to reach a consensus with the follow-up staff on the habits of the surveyors, which is not easy to record and understand. The invention provides a hole position and size detection tool o...
