Problems solved by technology

In addition, the fuzes of RPG-7 and other rocket launchers are inertial fuzes. Although the tolerance to acceleration inertia is strong, it is still difficult to meet the electronic control requirements of missiles for fuzes.

Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0035] like Figure 1-3 As shown, a miniature missile fuze of the present invention includes a fuze body, a firing pin seat 3 arranged in the fuze body, a firing pin body 9, a firing pin spring 7, a firing pin 8, a firing pin cover 10 and a lock 19 , and the fuze cover 26 and the safety bolt 30; the expansion chamber casing 1, the safety chamber casing 13, the fuze cover 26, the firing pin body 9, the firing pin seat 3 and the locker 19 are all formed by photocuring 3D printing of resin material.

[0036] The fuze body includes an explosion chamber housing 1 and an insurance chamber housing 13, the explosion chamber housing 1 and the insurance chamber housing 13 are cylindrical, the top end is closed, the bottom end is open, and the bottom of the explosion chamber housing...

Abstract

The invention provides a mini-type guide missile fuse. The mini-type guide missile fuse comprises a fuse body, a firing pin seat, a firing pin body, a firing pin, a firing pin sleeve and a locking device which are arranged in the fuse body, and a safety bolt. The mini-type guide missile fuse provided by the invention has a complete safety structure; a safety manner combining manual and electric operation is adopted, and manual safety is realized through the safety bolt; automatic safety is realized through a guide missile central computer, a stepping motor, the locking device and the firing pin body; an elastic force is generated through a firing pin spring to resist axial movement of the firing pin and the firing pin body to realize speed-reduction safety. According to the mini-type guidemissile fuse, almost parts are molded through carrying out photo-curing and 3D (Three Dimensional) printing on a resin material; the mini-type guide missile fuse is slow in cost, reliable in structure strength and convenient to assemble; the working stability of the fuse can be ensured and the requirements of rapid dismounting and maintenance are met.

Description

technical field [0001] The invention relates to the technical field of fuzes, in particular to a miniature missile fuze. Background technique [0002] Existing mortar, cannon, and howitzer projectile fuzes mostly use bulky solid metal parts in design, with a dead weight of up to several hundred grams or even kilograms, and the processing is complicated and expensive. If it is directly transplanted and used, it will cause waste on the mass load of the missile, occupy the mass space of other components, and reduce the performance of the missile. For example, the classic "Force 1-A" type fuze uses a solid copper structure in the design of the fuze body, and the overall appearance is heavy. [0003] The grenade fuze is mostly a delay fuze or a touch fuze. Among them, the time-delay fuze is only suitable for use as an overtime self-destruct device. The grenade touch fuze is sensitive to disturbance and cannot withstand the acceleration inertia of the missile. In addition, the...
