Part surface hole position size detection tool

Abstract

The invention belongs to the machining inspection and precision measurement field and relates to a part surface hole position size detection tool. The part surface hole position size detection tool includes a diameter ruler, a measuring assembly and a positioning assembly; a fixing base is fixed onto one end of the diameter ruler; the other end of the diameter ruler is slidingly sleeved with a movable base; the diameter ruler is slidingly provided with a main vernier; the measuring assembly is fixed onto the bottom of the main vernier; the measuring assembly comprises an angle scale, an anglemeasuring dial and an auxiliary measuring ruler; the angle scale is fixed on the main vernier; the angle measuring dial is rotationally arranged on the angle scale; the auxiliary measuring ruler is fixed onto the angle measuring dial; the auxiliary measuring ruler is perpendicular to the axis of the angle scale; the auxiliary measuring ruler is slidingly provided with an auxiliary vernier; the positioning assembly is fixed onto the bottom of the auxiliary vernier; the positioning assembly includes a positioning rod of which one end is arranged 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 which can be folded towards a measuring plane; and the positioning rod is parallel to theaxis of the angle scale.

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...
