Problems solved by technology

When measuring with a height gauge and a lever gauge, only a few fixed feature points can be measured, and the measurement accuracy is low
Measuring with a three-coordinate measuring machine has expensive equipment, and it is necessary to import the 3D digital model of the part. The measurement process is cumbersome, and only a limited number of points can be printed on the wing, and the measurement data of the entire wing surface cannot be displayed at all times. The inspection cost is expensive. Disadvantages such as high quality requirements

Embodiment

[0021] exist figure 1 Insert the T-slot nut into the T-slot of the base 9, screw the column 2 into the T-slot nut 10, put the gasket 8 on the column 2, tighten the lock nut 7 to fix the column 2 on the base 9 superior. Insert the U-shaped table frame 3 onto the column 2, and tighten the locking screw 1 to fix the U-shaped table frame 3 to the column 2. Insert the upper dial indicator 4 and the lower dial indicator 6 into the two holes of the U-shaped meter frame 3 respectively, and screw four jacking screws 5 at the side threaded holes of the U-shaped meter frame 3, and put the upper dial indicator 4 and lower dial gauge 6 are fixed with U-shaped table frame 3. By tightening and loosening the locking nut, the position of the T-slot nut 10 in the trapezoidal groove of the base 9 can be adjusted. Such as figure 2 Show, this U-shaped table frame 3 is processed into with the higher tool steel of hardness or quenched structural steel. There is a groove on its left end, when t...

Abstract

The invention relates to a device used for testing the guided missile model wing or rudder assembling precision, and belongs to the technical field of the guided missile model detection. The device comprises a locking screw, a stand column, a U-shaped dial indicator bracket, an upper dial indicator, a puller screw, a lower dial indicator, a locking nut, a gasket, a base and a T-shaped slot nut. The double-dial-indicator structure in the device disclosed by the invention has the advantages of simple structure, high measurement precision, low measurement cost and simple measurement process, any position of the whole wing surface can be measured, and measurement data can be displayed constantly.

Description

technical field [0001] The invention relates to a device for testing the assembly accuracy of missile model wings or rudders, and belongs to the technical field of missile model detection. Background technique [0002] The processing accuracy of the wind tunnel experimental model has a great influence on the experimental data. In particular, the assembly accuracy of the missile's wings and rudders has the greatest impact on the accuracy of the experimental data, and ultimately affects the missile's hit accuracy. Therefore, when assembling the wing and rudder of the missile wind tunnel model, the tolerance of the installation angle and roll angle is required to be less than or equal to 3 points, and the vertical deviation of the installation position from the axis of the missile body is required to be less than or equal to 0.1mm, and the installation accuracy is very high. However, since the upper and lower surfaces of the wing and rudder are composed of a plurality of symme...
