Abstract

The invention discloses a device for measuring the diameter of an internal slot, and the device comprises a measuring substrate. The measuring substrate is provided with a horizontally arranged measuring table, and the measuring substrate is provided with a horizontally telescopic ejector rod, wherein the ejector rod and a measuring rod on the measuring substrate are set coaxially and extend in opposite directions. The upper end of the measuring substrate is sleeved by a rotating sleeve, and the outer side of the rotating sleeve is provided with a cam structure which is adapted to the inner end of the ejector rod. The outer side of the measuring substrate is provided with elastic supports which are symmetrically arranged at both sides of the measuring rod. The device provided by the invention is convenient to operate and read when the device in use, and solves a difficulty that the diameter cannot be measured under the condition that a measuring head cannot be placed in the internal slot. The device is precise in measurement, and is small in measurement error. During measurement, the device is not liable to jitter, and is not liable to be affected by external factors.

Description

technical field [0001] The invention relates to the technical field of engines, more specifically, it relates to an inner groove diameter measuring device. Background technique [0002] At present, the measurement of the diameter ФA of the inner groove in the inner hole is usually measured by a three-coordinate machine or an inner diameter gauge, and some are measured by an internal micrometer. For the occasions where the inner groove can be put into the probe, it is reasonable to use the above-mentioned measuring instrument and the three-coordinate machine for measurement, but for the occasion where the inner groove cannot be put into the probe, to measure the diameter ФA of the inner groove in the inner hole, it is necessary to use Dedicated device, troublesome detection, long time consuming. Contents of the invention [0003] The technical problem to be solved by the present invention is aimed at the above-mentioned shortcomings of the prior art, and the purpose of the...
