Description

Technical Field

[0001] This utility model relates to a centrifugal tooling for quick clamping, belonging to the field of rapid clamping and local protection for centrifugal testing of sensitive pyrotechnic components in missile manufacturing. Background Technology

[0002] For sensitive pyrotechnic components undergoing centrifugal testing, the threaded connection between the protective cover and the connecting base is time-consuming and labor-intensive, and carries the risk of accidental explosions. Currently, protection is achieved by adding larger protective plates or covers to the equipment; however, safety measures for component testing fixtures are limited, and their condition cannot be promptly assessed, potentially leading to accidental explosions. Therefore, this invention proposes a quick-clamping, easily observable centrifugal fixture that guides the release of explosive energy. After loading the sensitive pyrotechnic component to be tested into the quick-clamping centrifugal fixture, a protective cover with explosion-proof glass is fitted onto the connecting base. A positioning pin, compressed by a cylindrical spring, engages the protective cover. The protective cover features an observation design with explosion-proof glass, allowing for confirmation of the component's condition after centrifugation. Even in the event of an accident, the connecting base is designed with explosion-proof holes to guide and release explosive energy in a timely manner, ensuring safe operation and rapid clamping. Utility Model Content

[0003] The purpose of this invention is to solve the problems of rapid clamping of sensitive pyrotechnic components before centrifugal testing, easy observation and confirmation during centrifugal testing, and the need to detonate pyrotechnic components in special circumstances, so as to achieve safety protection and reuse. It proposes a centrifugal fixture that can be quickly clamped, easy to observe, reliably detonated, and reusable, thus achieving the goal of reusing the centrifugal fixture.

[0004] The objective of this utility model is achieved through the following technical solution.

[0005] This utility model proposes a centrifugal tooling for quick clamping, comprising: a protective cover, explosion-proof glass, a positioning pin, a screw ring, a cylindrical spring, and a connecting base.

[0006] The protective cover, explosion-proof glass, positioning pin, screw ring, and cylindrical spring enable quick clamping, while the protective cover, explosion-proof glass, and connecting base enable explosion relief and protection.

[0007] The top inner cavity of the protective cover has a circular groove, and the explosion-proof glass is embedded in the circular groove on the protective cover and fixed by adhesive.

[0008] The protruding fixing pins on the connecting base position the component with the sensitive pyrotechnic material on the connecting base through the bottom groove on the component with the sensitive pyrotechnic material. The connecting base has a detonation hole.

[0009] The locating pin and spring are fixed to the connecting base by screws.

[0010] The protective cover with explosion-proof glass is fitted onto the connecting base. The positioning pin compresses the spring to install the protective cover in place. By rotating the protective cover appropriately, the positioning pin pops out of the through hole of the protective cover and is fixed, achieving quick positioning and clamping. After the centrifugal test is completed, the positioning pin is compressed, and the protective cover with explosion-proof glass is quickly lifted to remove the product and complete the unloading.

[0011] Working principle

[0012] Place the component containing the sensitive pyrotechnic material into the inner cavity of the connecting base. The bottom groove of the component engages with the protruding fixing pin at the bottom of the connecting base's inner cavity. Then, place the protective cover and explosion-proof glass onto the outer cylinder of the connecting base. By compressing the positioning pin, the positioning pin compresses the spring. After the protective cover is in place, the positioning pin pops out from the through hole of the protective cover, securing it and achieving rapid positioning and clamping. After the centrifugal test is completed, manually compress the two positioning pins to release the positioning pins from the protective cover with the explosion-proof glass. Then, lift the protective cover with the explosion-proof glass upwards and remove the component containing the sensitive pyrotechnic material, completing the operation.

[0013] When sensitive pyrotechnic components need to be tested for ignition, after the above operation, the component ignites, and the detonation energy is conducted downward through the detonation hole of the connecting base and discharged through the detonation holes on both sides, thereby achieving energy detonation; the top of the connecting base is protected by a protective cover with explosion-proof glass to provide upper protection for the energy, thereby achieving the safety protection function during operation.

[0014] Beneficial effects

[0015] This utility model proposes a quick-clamping centrifugal fixture. When centrifugation testing is required, the protective cover, positioning pin, and spring work together to achieve quick clamping and fixation. The protective cover features an observation design and is equipped with explosion-proof glass to confirm the state of the components after centrifugation. When ignition testing is required, the energy direction can be changed through the pre-machined explosion-proof hole on the connecting base, achieving local protection and enabling the centrifugal fixture to be reused. It has practical value in operation.

[0016] This utility model has the advantages of simple structure, quick clamping, reliable protection, and reusability. Attached Figure Description

[0025] This invention relates to localized safety protection and rapid clamping of sensitive pyrotechnic components during centrifugal testing. A rapid-clamping centrifugal fixture, under centrifugal force, moves two locating pins outward to further secure the protective cover. Explosion-proof glass is installed on the end face of the protective cover, facilitating observation of the movement of the sensitive pyrotechnic components. A detonation guide hole is provided on the connecting base, allowing for the orderly guidance and detonation of detonation energy when ignition verification is required. This achieves the functions of observation, protection, and detonation, realizing rapid clamping, isolation, safety, protection, and reusability. It is suitable for environments where sensitive pyrotechnic components are centrifuged after assembly, ensuring safe operation, localized isolation and guided detonation of detonation energy, and preventing hazards and sympathetic detonation.

[0029] The top inner cavity of the protective cover 1 has a circular groove, and the explosion-proof glass 2 is embedded in the circular groove on the protective cover 1 and fixed by adhesive.

[0030] The two protruding fixing pins on the connecting base 6 position the component with the sensitive pyrotechnic material on the connecting base 6 through the bottom groove on the component. The connecting base 6 has a detonation hole, positioning holes on both sides of the connecting base 6, and through holes on both sides of the protective cover 1.

[0032] Protective cover 1 and explosion-proof glass 2 are fitted onto connecting base 6. Positioning pin 3 compresses spring 5 to install protective cover 1 in place. By rotating protective cover 1 appropriately, positioning pin 3 pops out from the through hole of protective cover 1 and is fixed, achieving quick positioning and clamping. After centrifugal test is completed, positioning pin 3 is compressed, and protective cover 1 with explosion-proof glass 2 is quickly lifted to remove the product and complete unloading.

[0033] Working principle

[0034] Place the component containing the sensitive pyrotechnic material into the inner cavity of the connecting base 6.
