Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of missile warhead mass, centroid and mass eccentricity testing, and particularly relates to a missile warhead marking quantity testing tooling. Background Art
[0002] The mass, centroid and mass eccentricity of a missile warhead are important performance parameters of the warhead, which are related to the ballistic stability, range and target accuracy of the warhead during flight. Each missile warhead must be tested to determine whether its mass, centroid and mass eccentricity are within the designed range. If the mass, centroid and mass eccentricity exceed the designed values, this warhead is a non-conforming product. Therefore, the mass, centroid and mass eccentricity of a missile warhead are important indicators for measuring whether a missile warhead is qualified. When testing a missile warhead, a special tooling is required to clamp and rotate the warhead. Since the diameter and shape of each warhead are different, different toolings are needed for product testing. Special testing toolings need to be designed and manufactured for different types of warheads, which not only increases the production cost but also increases the difficulty of storage (large toolings and many varieties). In order to ensure the testing accuracy of each product and reduce the storage space, it is necessary to develop a testing tooling with strong versatility. Content of the Utility Model
[0003] Based on the above problems, the purpose of the utility model is to provide a missile warhead marking quantity testing tooling. When testing the mass, centroid and mass eccentricity of a missile warhead, a special support and cartridge clamping tooling is designed for a testing device, and the measurement of different products can be achieved by replacing the inner lining clamping ring.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: a missile warhead marking quantity testing tooling, including an outer clamping ring and an inner lining clamping ring. The outer clamping ring is formed by butting two half rings into a ring body. The inner lining clamping ring is adapted to the outer clamping ring and is detachably connected to the outer clamping ring. There are multiple inner lining clamping rings, which are evenly arranged along the inner wall of the outer clamping ring.
[0005] Further, there are 3 - 6 inner lining clamping rings, and the inner lining clamping rings are arranged on the inner wall of the outer clamping ring.
[0006] A positioning surface control device is provided on the inner wall of the outer clamping ring.
[0007] Silicone rubber sheets are provided on the contact surfaces between the inner lining clamping rings and the warhead body.
[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: (1) The utility model provides a test tooling for measuring the mass, centroid and mass offset of missile warheads of different models on test equipment of the same specification. The external clamping ring of this tooling is a universal clamping ring, and the internal connecting lining clamping ring is connected to the external clamping ring by bolts. After assembly, it can realize the support of the front and rear support positions of the missile warhead, and realize the measurement of the mass, centroid and mass offset of the missile warhead. This tooling can save production costs and storage space, and reduce the number of tooling stored. (2) This design method is universal and can be used for test equipment of different specifications. It is applicable to the measurement of warheads of any model and weight. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Referring to Figures 1-5 shown, a test tooling for missile warhead marking quantity includes an external clamping ring 1 and a lining clamping ring 2. The external clamping ring is composed of two half rings butt-jointed to form a ring body, and is fixed by a first bolt 4 during use. The lining clamping ring 2 is adapted to the external clamping ring 1 and is detachably connected to the external clamping ring; there are multiple lining clamping rings, which are evenly arranged along the inner wall of the external clamping ring. This solution aims to provide a test tooling for measuring the mass, centroid and mass offset of missile warheads of different models on test equipment of the same specification. First, determine the inner diameter size of the lining clamping ring of the test tooling according to the outer shape structure size and support position of the missile warhead. For example, Figure 5 , the test tooling is arranged at the front and rear ends of the missile body; select the outer diameter size of the external clamping ring of the test tooling at the support position of the equipment according to the model of the test instrument; secondly, determine the inner diameter size of the external clamping ring according to the mass and outer shape size of the warhead. When designing this external clamping ring, the mass measurement range of the test equipment should be considered, and it should be universal on the premise of meeting the strength requirements at the maximum mass; finally, design the outer diameter size of the lining clamping ring according to the inner diameter size of the external clamping ring to ensure that the lining clamping ring can be adapted to the external clamping ring and can be clamped and positioned.
[0015] There are 3 to 6 inner lining snap rings, which are fixed to the inner wall of the outer snap ring through the second bolts 5. When testing products of different models, just replace the inner lining snap rings of the corresponding products.
[0016] A positioning surface control device is provided on the inner wall of the outer snap ring. Specifically, a positioning groove is provided on the inner wall of the outer snap ring, and the positioning groove on the outer snap ring restricts the rotation of the inner lining snap ring.
[0017] Such as Figure 1 As shown, a silicone rubber sheet 3 is provided on the contact surface between the inner lining snap ring and the projectile body 6 to protect the projectile body from being scratched.
[0018] Such as Figure 5 As shown, when testing the mass, center of mass and mass offset of the missile warhead, replace the inner lining snap ring of the corresponding warhead with the outer snap ring supporting this equipment. Place the front and rear outer snap rings at the two supporting positions of the testing equipment, place the warhead at the center of the inner lining snap ring, and use the outer snap ring to hold the missile warhead firmly. When testing, the warhead drives the front and rear supporting outer snap rings to rotate 360° on the testing equipment, and thus the measurement of the mass, center of mass and mass offset of the missile warhead can be satisfied.
