Abstract

The invention belongs to the technical field of machining detection and precision measurement, and specifically relates to a deep hole diameter and depth detection tool. The deep hole diameter and depth detection tool includes a center pole, a plurality of isometric lower measuring poles and a plurality of isometric upper measuring poles, wherein one end of each lower measuring pole is hinged to the lower part of the center pole, and the other end of each lower measuring pole is hinged to one end of the corresponding upper measuring pole, and the other end of the upper measuring pole is arranged on the center pole in a sliding manner; a plane formed by the axle center of the each lower measuring pole and the axle center of the each upper measuring pole passes the axle center of the centerpole; a diameter scale and a locating cone which are parallel to the center pole are arranged on the center pole; the locating cone is arranged between the diameter scale and the upper measuring poles, and the locating cone and the center pole share the axle center; one end, connecting with the center pole, of each upper measuring pole, is hinged to a long handle which is parallel to the center pole; the long handle penetrates through the locating cone in a sliding manner; and scales are arranged on the periphery of the center pole, the diameter scale and the locating cone.

Description

technical field [0001] The invention belongs to the technical field of machining detection and precision measurement, and in particular relates to a deep hole diameter and depth detection tool. Background technique [0002] Deep hole processing is a very common processing step in processed products. For deep hole parts with complex internal structures, the position to be measured is often unknown during measurement, and the measurement tool cannot be sent to, or the internal structure of the measured part is complex and the relevant dimensions interfere with each other. , or the measurement space is narrow, the measurement human error is large, and the measurement results are difficult to read, etc., but the cost of accurate three-coordinate measurement is high, and it is not suitable for on-site measurement. How to accurately measure the diameter of each part inside the deep hole, and the The position of the length section in the whole part is a very common problem. The dee...
