Description

Technical Field

[0001] This utility model relates to the field of fuse recoil safety testing technology, and in particular to a recoil safety testing fixture. Background Technology

[0002] The recoil safety mechanism is part of the fuze safety system. From a safety perspective, the recoil safety prevents premature detonation due to accidental disengagement during handling operations such as transport and pre-loading, ensuring the safety of operators and preventing accidental internal explosions within the weapon system, thus protecting the weapon from damage. From a reliability perspective, testing ensures that the recoil safety disengages correctly during ammunition firing, allowing the ammunition to detonate as intended, guaranteeing the weapon system's operational effectiveness. Recoil safety testing typically employs hammer impact, live-fire testing, or centrifugal testing. Hammer impact overload is difficult to adjust and can easily damage fuze components; furthermore, hammer impact testing is a sampling inspection, making 100% accuracy impossible. Live-fire testing consumes a significant amount of fuze energy and incurs high transportation and testing costs. However, existing centrifugal testing methods lack reliable fixtures to secure the fuze to the centrifuge. Utility Model Content

[0003] The purpose of this invention is to provide a recoil safety testing fixture to solve the problems mentioned in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a recoil safety test fixture, including a cover plate, a support, a support sleeve and a hand-tightening screw. The cover plate is located above the support and has a through hole. The support has a central hole, and the position of the central hole corresponds to the position of the through hole. The support sleeve passes through the through hole and the central hole. The hand-tightening screw passes through the cover plate and the support sleeve in sequence and is connected to the support.

[0005] Preferably, the number of through holes is one, and the number of center holes is equal to the number of through holes.

[0006] Preferably, the number of openings in the support sleeve is equal to the number of openings in the through hole.

[0007] Preferably, the wall of the central hole is provided with internal threads, the outer surface of the hand screw is provided with external threads, and the hand screw passes through the cover plate and the support sleeve in sequence and is threadedly connected to the support.

[0008] The beneficial effects of this utility model are:

[0009] This utility model discloses a recoil safety testing fixture. The support can simultaneously mount two fuse mechanisms for centrifugal recoil safety testing. The cover plate can lock the clockwork mechanism on the upper surface of the fuse mechanism, fixing it in place and preventing movement. This utility model's recoil safety testing fixture can meet the testing requirements of electromechanical and piezoelectric fuses with vertical clockwork mechanisms. The thread direction connecting the support and the centrifuge should be consistent with the centrifuge's rotation direction; that is, the connection between the support and the centrifuge becomes increasingly secure as they rotate. The support is reliably connected to the centrifuge via threads, and the testing process effectively eliminates human interference, saving time and manpower and improving efficiency.
