[0024] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of an intelligent ammunition comprehensive geometric performance detection system of the present invention in conjunction with the accompanying drawings.

[0025] like Figure 1 As shown, the intelligent ammunition comprehensive geometric performance detection system of this embodiment tests the comprehensive geometric parameters of the rocket by designing the equipment structure and updating the measurement method, and includes a ground fixing block 1, an aluminum alloy support frame 2, a weighing sensor 3, a strip-type ranging sensor 4, a point-fire ranging sensor group 5, a rotating drive support wheel 6, a high and low lifting support wheel 7, a measuring platform 8, a movable sensor module 9 and a product limit block.

[0026] The bottom of the aluminum alloy support frame 2 is provided with a ground fixing block 1, and the entire detection system is stabilized on the ground through the ground fixing block 1; the measuring platform 8 is arranged on the top of the aluminum alloy support frame 2; a number of weighing sensors 3 are arranged between the aluminum alloy support frame 2 and the measuring platform 8, for reading the pressure values ​​at different points; the rotating drive support wheel 6 and the high and low lifting support wheel 7 are arranged above the measuring platform 8, for supporting the front and rear ends of the rocket respectively. At the same time, a product limit block is also arranged on the measuring platform 8, for limiting the space for placing the rocket. The strip-type ranging sensor 4, the point-shooting ranging sensor group 5 and the movable sensor module 9 are all arranged above the measuring platform 8.

[0027] like Figure 2 As shown, the movable sensor module 9 includes a strip photoelectric sensor 16, a lead screw guide 17, a coupling 18 and a second servo motor 19. The lead screw guide 17 is connected to the measuring platform 8, and the second servo motor 19 is connected to the lead screw guide 17 through the coupling 18, and the strip photoelectric sensor 16 can move on the lead screw guide 17.

[0028] like Figure 3 As shown, the rotation driving support wheel 6 is connected to the first servo motor 10. During the test, the rotation of the rotation driving support wheel 6 driven by the rotation of the first servo motor 10 drives the rocket to rotate.

[0029] like Figure 4 As shown, the height lifting support wheel 7 includes a support body 11, an oblique lifting mechanism 12, a cylinder position sensor 13, a cylinder coupling 14 and a bar cylinder 15. The bar cylinder 15 is connected to the oblique lifting mechanism 12 through the cylinder coupling 14, the support body 11 is connected to the oblique lifting mechanism 12, the oblique lifting mechanism 12 is arranged above the measuring platform 8, and a cylinder position sensor 13 is arranged on the side of the bar cylinder 15. By adjusting the position of the bar cylinder 15 to produce forward and backward displacement, the oblique lifting mechanism 12 can convert the horizontal displacement into the vertical displacement, thereby realizing the lifting and lowering adjustment of the rocket.

[0030] The cylinder position sensor 13 can provide real-time feedback on the position of the strip cylinder 15. According to the length of the rocket, the movable sensor module 9 rotates the second servo motor 19 to move the lead screw guide rail successively, and adjusts the position of the strip photoelectric sensor 16. The L-type coupling can reduce space occupation.

[0031] According to the size of different types of ammunition, the height lifting support wheel 7 is adjusted to make it level, thereby increasing the accuracy of ammunition measurement. In addition, the rotation driving support wheel 6 is driven by the rotation driving support wheel of the first servomotor 10, and the friction driving ammunition rotates.

[0032] The point-shooting distance measuring sensor group 5 is arranged above the measuring platform 8, and is composed of 5 point-shooting photoelectric sensors, of which four point-shooting photoelectric sensors are projected in pairs on the same horizontal plane, and the fifth point-shooting photoelectric sensor is in the same vertical plane as the two horizontally projected sensors at the tail end and is directed upward.

[0033] like Figure 5-Figure 7 As shown, the intelligent ammunition comprehensive geometric performance detection system of the present invention has a measurement parameter algorithm that mainly includes the maximum thickness, length, center of mass, mass deviation, weight, bullet tip groove width and maximum outer diameter of the ammunition cartridge.

[0034] Through two groups of point-shooting photoelectric sensors arranged in opposite directions, it can be determined whether the rocket is placed vertically on the horizontal plane. Through the strip photoelectric sensor 16 and the strip ranging sensor 4, the projected cross-sectional size of the rocket can be obtained, so that the length L of the rocket can be calculated; through four pressure sensors, the weight value G of the rocket can be obtained;

[0035] Center of mass measurement: project the whole device to the side parallel to the rocket, combine the values ​​of the two front weighing sensors to get F2, and combine the values ​​of the two rear sensors to get F1. L1 is the distance between the rocket and the rear weighing sensor, and L2 is the distance between the rocket and the front weighing sensor. L1 and L2 can be obtained by strip photoelectric sensors according to the formula:

[0036] X2=F1*(L1+L+L2) / G-L2 (1)

[0037] X1=F2*(L1+L+L2) / G-L1 (2)

[0038] L=X1+X2 (3)

[0039] L: rocket length;

[0040] L1: The distance between the rocket and the rear weighing sensor;

[0041] L2: distance between the rocket and the front load cell;

[0042] G: rocket weight;

[0043] F1: The sum of the values ​​of the two subsequent load cells;

[0044] F2: The sum of the values ​​of the two weighing sensors at the front end;

[0045] The distance between the center of mass and the front and rear ends of the rocket can be obtained.

[0046] Similarly, the method for measuring mass deviation is to project the entire device to the side perpendicular to the rocket, and the mass deviation can be obtained based on the calculation formula of the center of mass.

[0047] The maximum wall tube thickness is obtained by collecting data based on the rear-end strip-type ranging sensor to obtain the thickness dimension of a cross section. The wall thickness is continuously collected during the rotation of the rocket to form a curve with the rotation angle as the horizontal axis and the wall tube thickness as the vertical axis. The maximum wall tube thickness value is obtained through the curve.

[0048] The maximum outer diameter is measured based on the readings of the point-fire photoelectric ranging sensor. There are three point-fire photoelectric sensors at the tail of the rocket, one vertically facing upward and two horizontally facing each other. The light spots of the facing light coincide with the diameter of the projectile. Figure 7 When the rocket is in a rotating state, the data results of the two sensors are recorded and added together. The minimum value of the result is the state at the maximum outer diameter. The maximum outer diameter is obtained by subtracting the sum of the installation positions of the two sensors.

[0049] D=Y-L3-L4 (4)

[0050] Y: Installation distance of the through-beam photoelectric sensor;

[0051] L3, L4: distance from two sensors to the projectile surface

[0052] During the actual placement process, due to the influence of gravity, there will be a downward displacement △x, causing the laser point to deviate from the diameter position. The result can be corrected through algorithm calculation, such as Figure 7 Hint.

[0053] D=4△x2 / X+X (5)

[0054] D: Actual diameter of the rocket;

[0055] X: Measure the diameter.

[0056] Beneficial effects of this embodiment:

[0057] (1) The present invention has strong structural stability and is mainly used for measuring physical quantities of various types of rockets, with a certain degree of flexibility. In addition, the measurement items are more and more integrated, which improves the efficiency of measurement work. At the same time, for the scientific research measurement items of scientific research products, the sensor position can be adjusted according to the measurement requirements, and the measurement of non-design functions can be realized.

[0058] (2) The present invention adopts non-contact measurement, which can effectively protect the appearance of the product from being damaged.

[0059] (3) This product adopts automatic test mode, which can communicate and interact with the production line system to achieve completely unmanned measurement. At the same time, a manual measurement function is added, which can measure only some of the measurement items as needed to improve flexibility.

[0060] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, it is apparent to those skilled in the art that several modifications and improvements may be made without departing from the principles of the present invention, and these modifications and improvements should also be considered to fall within the scope of protection of the present invention.
