Side direction hydraulic pressure calibration adjustable support of vertical type six-component test bed

Abstract

The invention discloses a side direction hydraulic pressure calibration adjustable support of a vertical type six-component test bed. The side direction hydraulic pressure calibration adjustable support of the vertical type six-component test bed comprises a height adjusting plate, adjusting welded rods, threaded sleeves, bolts, an inner thread tapered pin, a first bolt, a first spring washer, a base plate, stand columns, a panel, a second bolt and a second spring washer. Second thread via holes are formed in four corners of the height adjusting plate, and the height adjusting plate is fixed on a test bed fixed frame through the second bolt and the second spring washer. A first thread via through is formed in the base plate, and the base plate is fixed on the center of the height adjusting plate through the first bolt and the first spring washer. The threaded sleeves are respectively arranged on two sides of the base plate, and installed on the height adjusting plate through the bolts, and the adjusting welded rods are matched with the threaded sleeves, and adjust the position of the base plate on the height adjusting plate. The four stand columns are welded on the base plate, and the panel is welded on the stand columns and parallel to the base plate. According to the side direction hydraulic pressure calibration adjustable support of the vertical type six-component test bed, position adjustment of a hydraulic system can be finished well, and centering of flexibility pieces and sensors in the process of calibration and working is guaranteed.

Description

technical field [0001] The invention relates to the field of measuring the thrust eccentricity of a solid rocket motor, in particular to a lateral hydraulic calibration adjustable support of a vertical six-component force test bench. Background technique [0002] The thrust eccentricity of the rocket motor is one of the main reasons for the large dispersion of the rocket, and the thrust eccentricity value test must be carried out for the designed solid rocket motor. At present, most of the common test schemes are six-component force test method, including vertical, horizontal and different deployment of sensors. The six-component force test bench is mainly composed of a moving frame and a fixed frame. The moving frame is fixed on the fixed frame with 6 sensor flexible parts assemblies, and the rocket motor is clamped on the frame. The purpose of using the flexible sensor assembly is to minimize the measurement error caused by the lateral movement of the sensor flexible ass...
