Artillery rotating radius and pitch radius detecting device and method based on laser radar

Abstract

The invention provides an artillery rotating radius and pitch radius detecting device and method based on a laser radar, and belongs to the field of laser measurement. On the basis of a laser radar technology, the artillery rotating radius and the pitch radius are indirectly measured by combining the artillery rotating radius and pitch radius detecting device based on the laser radar and using the similar triangle principle. The device comprises a rotating hand wheel, a lead screw, a spring ring, a sleeve, a positioning block, a conical body block, a laser radar and a plug gauge, wherein the rotating hand wheel is connected with the lead screw, the lead screw is arranged inside the sleeve and is coaxial with the sleeve, the positioning block is positioned at the outer side of the sleeve, the positioning block is connected with the sleeve through the spring ring, and the laser radar and the plug gauge are independent devices and are matched with the positioning block for completing the detection. The device and the method provided by the invention have the advantages that the rotating radius and the pitch radius of an artillery can be precisely measured, the measuring precision can reach the micrometer level, the measuring precision is greatly improved, in addition, the structure of the detection device is simple, the measuring process is simple, the implementation is easy, and the detection capability and the shaping test level of the shooting range artillery can be improved.

Description

technical field [0001] The invention belongs to the technical field of laser measurement, and in particular relates to a laser radar combined with a matching auxiliary measurement device to detect the gyration radius and pitch radius of a cannon. Background technique [0002] The radius of gyration and pitch radius of the artillery are important overall assembly technical parameters of the artillery, and are also important parameters involved in the calculation of the firing table programming test, so they are important parameters that must be measured in the artillery type test and firing table programming test. At present, the traditional method of measuring the pitch radius and gyration radius of the artillery is affected by the meter stick and the spatial position of the artillery, and its measurement accuracy is very low. The measurement of the two parameters of the cannon's gyration radius and pitch radius is still at the level of meter ruler measurement, and the measu...
