Multi-cone-section deep hole measuring device and using method thereof

Abstract

The invention discloses a multi-cone-section deep hole measuring device and a using method thereof. According to the multi-cone-section deep hole measuring device and the using method thereof, a three-jaw expansion mechanism is adopted, a front clamping jaw and a rear clamping jaw can move in the radial direction of a deep hole part through cooperation of a front center adjusting shaft, a rear center adjusting shaft, a large conical block and a small conical block, so that the front clamping jaw and the rear clamping jaw can make contact with the inner wall of a deep and long hole, and therefore accurate positioning of the measuring device in the deep and long hole is achieved; an explosive chamber aperture measuring mechanism with a horizontally-arranged detection gauge is adopted; the bottom of a swing type measuring head is contacted with the contact of the gauge, and the radial displacement change in the measuring process can be transmitted to the contact of the horizontally placedprobe gauge in a certain proportional relation, so that a precise measuring element with a larger structural size can be used in a narrow deep hole space, and the structural interference is avoided;the design that a measuring unit is independent of the whole measuring device is adopted, and the precision guarantee of axial movement of the measuring unit is achieved.

Description

technical field [0001] The invention belongs to the technical field of measuring devices, and in particular relates to a multi-cone section deep hole measuring device and a using method thereof. Background technique [0002] The artillery powder chamber is composed of multiple cone segments and cylindrical segments. The parameters of the powder chamber are important indicators that affect the performance of the artillery. The shooting accuracy and shooting accuracy of the artillery system are inevitably affected by the geometric parameters of the powder chamber. direct or indirect effects. Accurate measurement of the geometric quantity of gun powder chamber is an important part of gun barrel measurement. [0003] Since the gun powder chamber is a variable taper deep hole, there is an inflection point between the cones, the aperture has a large range of variation, the hole body is long, and the measuring instrument is affected by factors such as the gun structure and sensor ...

Problems solved by technology

[0003] Since the gun powder chamber is a variable taper deep hole, there is an inflection point between the cones, the aperture has a large range of variation, the hole body is long, and the measuring instrument is affected by factors such as the gun structure and sensor technology limitations, the geometric quantity measurement of the gun powder chamber and the object Compared with the measurement of the outline size, the measurement difficulty is relatively large, the measurement efficiency is low, and the measurement accuracy is insufficient. For a long time, there has been no good solution for the measurement of the geometric parameters of the drug chamber in my country.
