Problems solved by technology

After the spout is deflected by a certain azimuth vector, its axis forms a spatial angle. During manual measurement, the determination of the azimuth angle and the measurement plane are all based on visual inspection. The deflection angle of the spout is measured indirectly, and the angle value is obtained through calculation. The measurement accuracy is greatly affected by human factors, and the work efficiency is low

Abstract

The invention provides a nozzle deflection angle detection device. The nozzle deflection angle detection device is composed of a frame (1), a measuring structure, a telescopic mechanism (3) and a pneumatic control system. The measuring structure is located on the frame (1), the horizontal installing face of the frame (1) is attached to the end face of a nozzle (23), the positioning circle of the frame (1) is matched with the outer circle of the installing side of the nozzle (23), the nozzle (23) is installed on the frame (1), and a circumferential positioner (4) is designed on the frame (1). The nozzle deflection angle detection device can automatically measure vector nozzle deflection actual space angles, measuring accuracy reaches 0.1 degree, working efficiency is improved by 5 times, and high economic and social value is achieved.

Description

technical field [0001] The invention relates to the technical field of structural design and application of a detection device, and in particular provides a detection device for a nozzle deflection angle. Background technique [0002] After the vector nozzle is assembled, its action should be checked to verify the degree of conformity between the actual deflection angle and the given deflection angle during operation. After the spout is deflected by a certain azimuth vector, its axis forms a spatial angle. During manual measurement, the determination of the azimuth angle and the measurement plane are all based on visual inspection. The deflection angle of the spout is measured indirectly, and the angle value is obtained through calculation. The measurement accuracy is greatly affected by human factors, and the work efficiency is low. [0003] People are eager to obtain a nozzle deflection angle detection device with excellent technical effect. Contents of the invention ...
