Abstract
It is a kind of to be applied to low speed, low overload, the Zhe Fa insurance institutions of micro- rotating environment, it is made up of firing pin (1), inertia cylinder (2), inertia spring (3), steel ball (4), guide finger (5), inertia cylinder base (6), it is characterized in that：Firing pin (1) is constrained in inertia cylinder base (6) by inertia cylinder (2), inertia spring (3) and steel ball (4), guide finger (5) is riveted on inertia cylinder base (6), constraint of the inertia cylinder (2) by inertia spring (3), steel ball (4) and guide finger (5).The present invention has the features such as simple in construction, reliability is high, solves SLM105mm fuses reliable arming and problem of hair under low speed, low overload, micro- rotating environment.
Description
Technical field
The invention belongs to mechanical fuze technical field, it is related to a kind of suitable for low speed, low overload, micro- rotating machinery fuse
Zhe Fa insurance institutions, more particularly to bore hair insurance hair mechanism for 105mm certain mechanical nondelay fuse, can apply to simultaneously
In under low speed, low overload, micro- turning effort environment, the mechanical nondelay fuse of heavy caliber.
Background technology
The shooting environment of certain SLM105mm machinery nondelay fuses is low speed, low overload, micro- rotation, and existing hair at present
Insurance institution's environment is high overload, high rotation, therefore existing Zhe Fa insurance institutions can not be satisfied with the demand of the fuse.
The content of the invention
The purpose of the present invention is exactly that there is provided a kind of low speed, low overload, micro- rotation in order to overcome the shortcomings of above-mentioned background technology
The Zhe Fa insurance institutions of environment.
Zhe Fa insurance institutions under low speed involved in the present invention, low overload, micro- turning effort environment, by firing pin 1, inertia
Cylinder 2, inertia spring 3, steel ball 4, guide finger 5, inertia cylinder base 6 are constituted.Firing pin 1 is constrained in used by inertia cylinder 2, inertia spring 3 and steel ball 4
Property cylinder base 6 in, guide finger 5 is riveted on inertia cylinder base 6, inertia cylinder 2 by inertia spring 3, steel ball 4 and guide finger 5 constraint.
The low speed of the present invention, low overload, the Zhe Fa insurance institutions under micro- turning effort environment have that parts are few, structure is simple
It is single, the features such as reliability is high, solve SLM105mm fuses under low speed, low overload, micro- rotating environment reliable arming and
The problem of hair.

Embodiment
Below in conjunction with drawings and examples, the invention will be further described：
Embodiment
The present embodiment be the Zhe Fa insurance institutions that are applied on SLM105mm fuses of the present invention, its structure as shown in figure 1,
The Zhe Fa insurance institutions are made up of firing pin 1, inertia cylinder 2, inertia spring 3, steel ball 4, guide finger 5, inertia cylinder base 6.Firing pin 1 is by inertia
Cylinder 2, inertia spring 3 and steel ball 4 are constrained in inertia cylinder base 6, and guide finger 5 is riveted on inertia cylinder base 6, and inertia cylinder 2 is by inertia
The constraint of spring 3, steel ball 4 and guide finger 5.
Firing pin 1, inertia cylinder 2, inertia cylinder base 6 use aluminum alloy materials, it is ensured that the sensitivity of impact devide, alleviate
The weight of Zhe Fa insurance institutions, inertia 2 structures of cylinder on inertia cylinder 2 as shown in Fig. 2 be provided with snakelike tank, the process of arming is just
It is the process that inertia 2 snakelike tanks of cylinder are moved along guide finger 5, it is ensured that the distance of muzzle safety, guide finger 5 is riveted on inertia cylinder base
On 6.
The course of work of the present embodiment is：Fuse is in duties processing procedure, and firing pin 1 is by inertia cylinder 2, inertia spring 3 and steel
Ball 4 is constrained in inertia cylinder base 6, it is impossible to moved, it is ensured that safety of the fuse in duties processing procedure；After pellet injection, it is used to
Property cylinder 2 in the presence of inertia force, overcome the drag of inertia cylinder spring 3, snakelike tank moves downward along guide finger 5 and discharges upper steel ball
4, after inertia force reduces, inertia cylinder 2 under the effect of elastic resistance of inertia spring 3 on lift, the lower steel ball 4 of release releases the pact to firing pin 1
Beam, firing pin 1 is also with upper lift, fuse arming, in arm-to-arm；When fuse hits target, fuze cap crimp,
Drive firing pin 1 to move downward stamp and hit priming system, complete the Explosive sequence action of fuse.
The firing test that product is sent out by carrying out many rounds more than 100 to the present embodiment is verified, achieves fuse sparking rate
95% good result.
Above-mentioned experiment shows that the present invention solves SLM105mm fuses and reliably solved under low speed, low overload, micro- rotating environment
Except insurance and the problem of hair.
