Description

Technical Field

[0001] This utility model relates to the technical field of projectile detection equipment, specifically a projectile launching device detection device. Background Technology

[0002] The ejection bomb is a core component powered by propellant gas and is widely used in the aviation field for the ejection and separation of suspended missiles and bombs. Its working principle involves using high-pressure gas generated by propellant combustion to drive the ejection piston, achieving precise energy conversion control through an internal ballistic-gas dynamics coupling model.

[0003] However, as a crucial component, the projectile launcher tube must undergo rigorous testing before being put into use. Currently, existing launcher tube testing devices typically only support unidirectional testing and cannot integrate multiple testing functions, resulting in low testing efficiency. Therefore, we propose a projectile launcher testing device designed to improve testing efficiency and overall performance. Utility Model Content

[0004] The purpose of this invention is to provide a detection device for a projectile launching device. By using a combination of pressure measuring components, vibration components, and moving components, the device can perform multiple tests on the launching tube, thus solving the problem of the single detection function of existing detection devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A projectile launching device testing device includes a base plate, side plates symmetrically mounted on the base plate, and a back plate mounted on the base plate in the middle of the side plates. It further includes: a fixed seat slidably mounted on the base plate, the fixed seat having an arc-shaped groove inside, and compression springs symmetrically mounted inside the arc-shaped groove. Clamping plates are fixedly connected to the ends of two compression springs that are close to each other, the clamping plates being used to clamp the launching tube; a pressure measuring component mounted on the back plate, the pressure measuring component being used to perform pressure testing on the launching tube; a vibration component mounted on the base plate, the vibration component being used to perform vibration testing on the launching tube; and a moving component mounted on the side plates, the moving component being used to perform tensile testing on the launching tube.

[0006] Preferably, the pressure measuring component includes a hydraulic cylinder mounted on a back plate, and the output end of the hydraulic cylinder is fixedly connected to a pressure head, wherein there are multiple pressure heads.

[0007] Preferably, the vibration component includes a slider slidably mounted on a base plate, the top of the slider being fixedly connected to a fixed seat, and a connecting plate being symmetrically fixedly connected to the bottom of the slider, the connecting plate being L-shaped.

[0008] Preferably, the fixed base is symmetrically equipped with return springs on its exterior, and the ends of the two return springs away from the fixed base are fixedly connected to the back plate.

[0009] Preferably, a motor is mounted on the bottom of the base plate via a mounting bracket, and a bevel gear is fixedly connected to the output end of the motor via a coupling. A helical gear is externally meshed with the bevel gear, and a rotating shaft is coaxially fixedly connected to the helical gear. The rotating shaft is rotatably connected to the base plate via a mounting plate.

[0010] Preferably, the rotating shaft is symmetrically fixedly connected to a cam, and the position of the cam corresponds to that of the connecting plate.

[0011] Preferably, the moving component includes electrically operated telescopic rods symmetrically mounted on the side plate, and the output ends of both electrically operated telescopic rods are fitted with three-jaw chucks through the side plate.

[0012] Preferably, a cylinder is installed on the outside of one of the side plates, a push plate is fixedly connected to the output end of the cylinder, and the upper part of the push plate is fixedly connected to one of the electric telescopic rods, and a laser detector is installed on the other side plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model is equipped with a pressure measuring component. Through the cooperation of a hydraulic cylinder and multiple pressure heads, it is convenient to perform simultaneous multi-point pressure measurement on the transmitting tube, thereby improving the accuracy and efficiency of pressure measurement. At the same time, the fixed base is equipped with a compression spring and a clamping plate, which can accommodate transmitting tubes of different sizes, thus improving the adaptability of the detection device.

[0014] 2. This utility model includes a vibration component. A motor drives a bevel gear to rotate, which in turn rotates a helical gear shaft, causing a cam to strike the connecting plate and vibrate the fixed seat above the slider. Under the action of a return spring, the fixed seat reciprocates, facilitating vibration testing of the launching tube.

[0015] 3. This utility model includes a moving component. After the pressure and vibration tests are completed, a cylinder drives a push plate to move, causing one of the three-jaw chucks to clamp the transmitter tube under the drive of an electric telescopic rod. When it moves to the same height as the other three-jaw chuck, both chucks perform a tensile test on the transmitter tube. After the tensile test is completed, a laser detector can be used to inspect the surface and inner wall of the transmitter tube. This design features flexibility, high efficiency, and multifunctionality. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] The following description is intended to disclose the present invention and to enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0020] Example 1: Please refer to Figure 1 - Figure 6The diagram shows a testing device for a projectile launching mechanism, comprising a base plate 1, which is integrally formed from high-strength alloy steel plate with a thickness of 20mm. The surface is sandblasted and rust-removed before being coated with an anti-rust coating to ensure resistance to vibration, impact, and environmental corrosion during long-term use. Support legs are located at the bottom of the base plate 1, with anti-slip elastic pads underneath. Side plates 2 are symmetrically mounted on the base plate 1, made of the same material. A control panel is located on the exterior of the side plates 2 for controlling the circuitry and recording test values. A back plate 3 is mounted on the base plate 1, located between the side plates 2. The device also includes a fixed base 7 slidably mounted on the base plate 1. The fixed base 7 is made of cast iron and precision-cast, with an overall rectangular structure. The interior of the fixed base 7 contains a common type of launching tube. The outer contour is fitted with an arc-shaped groove, and the inner wall of the arc-shaped groove is inlaid with a 10mm thick wear-resistant nylon bushing to prevent scratching the surface of the launch tube during clamping. The arc-shaped groove is symmetrically installed with compression springs 8. The compression springs 8 are high-strength compression springs made of 60Si2Mn spring steel, and the elastic coefficient has been precisely calibrated. The ends of the two compression springs 8 that are close to each other are fixedly connected to clamping plates 9. The clamping plates 9 are used to clamp the launch tube. The clamping plates 9 are arc-shaped steel plates with the same curvature as the arc-shaped groove. The clamping surface of the clamping plates 9 is bonded with a 3mm thick anti-slip rubber pad. The surface of the rubber pad has anti-slip texture, which can not only improve the clamping friction, but also provide flexible protection for the launch tube, adapting to launch tubes of different sizes. Through the elastic force of the compression springs 8, the launch tube can be self-adaptively clamped. In addition, a pressure measuring component 4 is installed on the back plate 3, which is used to perform pressure testing on the launch tube; a vibration component 5 is installed on the base plate 1, which is used to perform vibration testing on the launch tube; and a moving component 6 is installed on the side plate 2, which is used to perform tensile testing on the launch tube.

[0021] Further reference Figure 2 and Figure 5 As shown, the pressure measuring component 4 includes a hydraulic cylinder 10 mounted on the back plate 3. The hydraulic cylinder 10 is a high-pressure single-acting hydraulic cylinder. The output end of the hydraulic cylinder 10 is fixedly connected to a pressure head 11. There are multiple pressure heads 11, which are made of hard alloy and are polished to avoid scratching the surface of the transmitter tube.

[0022] During operation, high-pressure hydraulic oil is supplied to the hydraulic cylinder 10 through the hydraulic control system, which pushes the piston to drive the pressure head 11 to move synchronously towards the launching tube. The four pressure heads 11 act on key stress areas such as the middle and near both ends of the launching tube, respectively, to achieve multi-point synchronous pressure measurement. The pressure value is fed back in real time by the pressure sensor installed in the oil circuit of the hydraulic cylinder 10. The pressure resistance of the launching tube is judged by comparing it with the preset threshold. Compared with single-point pressure measurement, this design greatly improves the accuracy and efficiency of detection.

[0023] Specifically, please refer to Figure 4 and Figure 6The vibrating component 5 includes a slider 17 slidably mounted on the base plate 1. The slider 17 is made of wear-resistant cast iron and its bottom is slidably engaged with a linear guide rail on the base plate 1. A guide sleeve is installed at the bottom of the slider 17 through the through hole in the base plate 1 to prevent displacement during movement (not shown in the figure). The top of the slider 17 is fixedly connected to the fixed seat 7. The bottom of the slider 17 is symmetrically fixedly connected to a connecting plate 19 through the base plate 1. The two connecting plates 19 are symmetrically welded to the bottom sides of the slider 17. The connecting plates 19 are L-shaped.

[0024] Meanwhile, symmetrical return springs 18 are installed on the outside of the fixed base 7. The return springs 18 are tension springs, and the material is also 60Si2Mn spring steel. The ends of the two return springs 18 away from the fixed base 7 are fixedly connected to the back plate 3. The return springs 18 maintain a slightly stretched state in their natural state to ensure that the initial position of the fixed base 7 is stable.

[0025] Specifically, a motor 20 is mounted on the bottom of the base plate 1 via a mounting bracket. The motor 20 is a servo motor. The output end of the motor 20 is fixedly connected to a bevel gear 21 via a coupling. A helical gear 22 is externally meshed with the bevel gear 21. A rotating shaft 23 is coaxially fixedly connected to the helical gear 22. The rotating shaft 23 is rotatably connected to the base plate 1 via a mounting plate. Cams 24 are symmetrically fixedly connected to the outside of the rotating shaft 23. The cams 24 are eccentric cams, and their positions correspond to those of the connecting plate 19.

[0026] During operation, the motor 20 starts and drives the bevel gear 21 to rotate, which in turn drives the helical gear 22 to rotate synchronously with the shaft 23. The cam 24 rotates with the shaft 23, and its rim hits the connecting plate 19, pushing the slider 17 to move the fixed seat 7 away from the back plate 3. At this time, the return spring 18 is further stretched, generating a rebound force. When the non-eccentric section of the cam 24 is opposite to the connecting plate 19, the return spring 18 pulls the fixed seat 7 to reset. This cycle is repeated to achieve the reciprocating vibration of the fixed seat 7. By adjusting the speed of the motor 20, different intensity vibration environments can be simulated to test the structural stability and component connection reliability of the transmitter tube under vibration conditions, which is convenient for vibration testing of the transmitter tube.

[0027] Example 2: This embodiment is a further explanation of Example 1, based on... Figure 1 - Figure 6 As shown, it is worth noting that the moving part 6 includes electric telescopic rods 12 symmetrically mounted on the side plate 2. The output ends of both electric telescopic rods 12 are connected to a three-jaw chuck 13 through the side plate 2. The three-jaw chuck 13 is a pneumatic three-jaw chuck, and the jaws are made of alloy tool steel. Soft rubber pads are bonded to the inside of the jaws to prevent damage to the launch tube during clamping. The clamping range of the three-jaw chuck 13 can be adjusted between 30 and 160 mm to accommodate launch tubes of different diameters.

[0028] Specifically, a cylinder 14 is installed on the outside of one of the side plates 2, and a push plate 15 is fixedly connected to the output end of the cylinder 14. The upper part of the push plate 15 is fixedly connected to one of the electric telescopic rods 12. A laser detector 16 is installed on the other side plate 2. The lens of the laser detector 16 faces the axis of the emitting tube, which can realize full coverage scanning of the outer surface and inner wall of the emitting tube.

[0029] During operation, based on the length of the transmitting tube, cylinder 14 activates to push push plate 15, causing one side of the electric telescopic rod 12 to move laterally. After adjusting to a suitable position, both sides of the electric telescopic rod 12 extend synchronously, driving the three-jaw chuck 13 to approach both ends of the transmitting tube. The three-jaw chuck 13 is then ventilated to clamp the transmitting tube. Subsequently, the two sides of the electric telescopic rod 12 move in opposite directions, applying a preset tension to the transmitting tube. The tension value is fed back in real time by a tension sensor installed inside the electric telescopic rod 12, detecting the tensile strength and fracture limit of the transmitting tube. After the tension test is completed, the electric telescopic rod 12 finely adjusts the position of the transmitting tube, and the laser detector 16 is activated, emitting a laser beam to scan the outer surface and inner wall of the transmitting tube. Through the image acquisition and analysis system, defects such as cracks, dents, and wear on the surface of the transmitting tube, as well as dimensional deviations and roughness of the inner wall, are identified. This achieves the integration of tension testing and appearance defect detection, featuring flexible operation, high detection efficiency, and diverse functions, meeting the multi-dimensional detection needs of the transmitting tube.
