An electronic plug gauge for measuring the diameter of hole structures

Abstract

The invention discloses an electronic plug gauge for measuring the diameter of a hole structure. The electronic plug gauge comprises a quartz cylinder (4) provided with a center through hole (5); two end faces of the quartz cylinder (4) are provided with a layer of metal film (3) respectively; wires (6) are respectively connected with the metal films (3); one end of the quartz cylinder (4) is fixed to a wire hole (1) of a mounting seat (2); the two wires (6) penetrate through the center through hole of the quartz cylinder (4) and the wire hole (1) of the mounting seat (2) and are connected with two poles of a direct current power supply. The electronic plug gauge is simple in structure, whether the size of a small hole to be measured meets the requirement of the upper and lower limit offset in the processing and using processes under the condition that the head position is not changed can be directly judged, the problem that a common plug gauge is required to be repeatedly clamped when being used is solved, the size can be accurately adjusted by an electric control method, and the integration in the integral processing system is facilitated.

Description

technical field [0001] The invention relates to an electronic plug gauge for measuring the diameter of a hole structure, belonging to the technical field of product structure. Background technique [0002] With the advancement of science and technology, people have put forward more and more stringent requirements for measuring devices, especially many measuring devices need to be integrated into the system, and it is necessary to gradually adopt automated methods to replace the fields that are usually measured by manual or mechanical methods. This requires a reasonable design of the measurement device to avoid repeated clamping of the test object or probe, which is conducive to the integration and optimization of the measurement system and the further improvement of the measurement accuracy. [0003] Many nozzle structures used in aero-engines, diesel engines and other power devices are difficult to quickly and accurately determine whether the nozzle aperture structure meets...

Problems solved by technology

It can be seen that when judging the processing of the hole, it is necessary to adjust the way the plug gauge penetrates into the hole, which will affect the simplified design of the integrated automatic measuring device

[0005] At present, there is no good technical means for the measurement of tiny holes. If other special measuring devices are used, there are disadvantages of bulky structure and complex system. The plug gauge is low in cost, fast in speed and high in efficiency, which can better meet It is required by industry, but if it is integrated into the overall system, the through end and stop end of the plug gauge need to be clamped and positioned repeatedly. If the two plug rules are used, the action during the test needs to be increased, which brings inconvenience to the test work
