Description

Circular Warhead Fasteners {FASTENER FOR ASSEMBLING BOMB OR DETACHING WARHEAD FROM IT}

The present invention relates to, for example, a warhead fastener for disassembling or assembling a round warhead and a finished coal, and more specifically, a round warhead fastening suitable for disassembling and assembling a warhead of a sample bomb during an ammunition test. It's about a phrase.

As conventional working tools that have been used for assembling and disassembling warheads, and as prior art in the art, the hook-type warhead fasteners shown in FIGS. .

As shown in these figures, the conventional hook-type warhead fastener has a square rod-shaped handle 1, a hook extending in a curved shape from one end of the handle, and a fastener 3 protruding from the tip of the hook. ) Is composed of one body.

However, in the case of disassembling and assembling a warhead with a hook-type warhead fastener of this configuration, there was a problem that the hook-head warhead fastener frequently detached from the warhead and had to repeat the same operation several times. As this lengthened, safety problems existed. For example, when using a hooked warhead fastener, the fastener 3 must be inserted into the lateral groove of the warhead and a force applied to the handle 1 to return the handle in either direction. Since the warhead fastener and the warhead are engaged only at one point, the engagement state of the hooked warhead fastener and the warhead is very unstable. As a result, hook-type warhead fasteners frequently escaped from the warhead. Therefore, when disassembling and assembling the warhead, there was a problem that the work time is long because the same work is repeatedly performed several times, and this repetitive work deforms both the side grooves of the warhead and the fastening faucet (3). Even when the work could not be performed smoothly.

The present invention has been invented to improve the problems of the prior art, and during the disassembly and assembly between the warhead and the finished coal, there is no detachment of the warhead fastener from the warhead, so that the workability of the circular warhead fastener is significantly increased than in the prior art. The purpose is to provide.

In addition, an object of the present invention is to provide a circular warhead fastener with a significantly shorter working time than the prior art and consequently shortening the handling time of the ammunition, thereby improving the safety of the work.

In addition, the present invention, once the warhead and the warhead fasteners are coupled once the stable state is maintained until the end of the operation is suppressed the occurrence of deformation due to frequent coupling and detachment between the warhead and warhead fasteners, warhead fastening than conventional It is an object to provide a circular warhead fastener that improves the durability of the sphere.

The present invention for solving the above-described problems, in the fastener used for disassembling and assembling the warhead and the finished coal, the entry into the circular warhead insertion hole and the warp side groove of the warhead is inserted. Torque transfer socket including a fixing pin that can be separated from (離 脫); And a handle for disassembling and assembling the torque transfer socket and transmitting the torque necessary for disassembling and assembling the warhead and the finished coal to the torque transfer socket in a state in which the torque transfer socket is assembled. Characterized in that comprises a. (See claim 1)

In one embodiment of the present invention, the torque transfer socket, the handle is composed of an annular fixed rim coupled to one side so as to be assembled and disassembled, and a rotation assembly rotatably coupled to the fixed rim. The rotating assembly may include a first annular cover plate in sliding contact with one side of the fixed rim, a second annular cover plate in sliding contact with the other side of the fixed rim, and an annular shape disposed inside the fixed rim. It consists of a latch, the annular latches being coupled to the first annular cover plate and the second annular cover plate, respectively, on both sides so that the fixed rim is located between the first annular cover plate and the second annular cover plate. One side to which the plate is coupled is formed with a fixing block for installing a fixing pin. (See claim 2)

Preferably, a torque wrench connecting hole is formed in this handle. (See claim 3)

In addition, a grip portion may be further formed on the handle. (See claim 4)

In addition, preferably by combining the handle and the fixed rim with a screwing stopper, the torque applied to the handle is transmitted to the annular latch through the screwing stopper while simultaneously tightening and loosening the screwing stopper. This makes it possible to disassemble and assemble the handle and the fixed rim. (See claim 5)

On the other hand, the terms or words used in the present specification and claims are based on the principle that the inventor can appropriately define the concept of terms in order to explain the invention in his best way, and the technical spirit of the present invention It should be interpreted as meanings and concepts corresponding to Therefore, this invention is not limited to the Example mentioned later.

According to the present invention configured as described above, by entering the fixing pin into the side groove of the warhead in the state where the warhead is inserted into the warhead insertion hole, the circular warhead fastener does not occur from the warhead. This allows you to complete the required tasks at once. As a result, the workability is remarkably increased, the working time is shorter than when using a conventional hook-type warhead fastener, and in particular, the handling time of ammunition that requires careful handling of the ammunition is absolutely shortened, and the safety is improved.

In addition, since the transmission of torque is surely made through the stable coupling between the round warhead fastener and the warhead, the assembly and disassembly between the warhead and the finished coal can be performed even without applying excessive force as in the prior art. As a result, deformation of the circular warhead fastener due to external force is suppressed, thereby increasing the durability of the device.

3 and 4 are exploded perspective views and real pictures showing the configuration of the circular warhead fastener according to an embodiment of the present invention.

As shown in these figures, the circular warhead fastener of this embodiment is composed of two parts, an annular torque transfer socket 13 and a handle 17, which are shown in FIG. The screwed stopper 19 is coupled to each other or disassembled.

The torque transfer socket 13 is rotatably coupled to an annular fixed rim 12 which is perforated so that the threaded portion of the screwing stopper 19 can penetrate on one side thereof. It consists of a rotating assembly. With the handle attached, the screwing stopper slightly protrudes into the fixed rim.

In addition, the rotary assembly, the annular latch 14 disposed inside the fixed rim, and the annular latch in the form of contacting one side of the fixed rim 12 in a state arranged inside the fixed rim of the annular latch A first annular cover plate 21 fixed to one side, a second annular cover plate 22 fixed to the other side of the annular latch 14 in contact with the other side of the fixed rim 12, The second annular cover plate is fixed surface 16 is formed on the surface is fixed.

And the fixing block, for example, when entering into the lateral groove of the warhead, by fixing the relative position between the warhead and the torque transfer socket 13, the fixing pin 15 which can transfer the torque required to separate or assemble the warhead and the finished coal (15). ) Is installed.

Since the tooth of the annular latch is directional, for example, as shown in Fig. 4, the torque can be transmitted in either direction, but the torque cannot be transmitted in the opposite direction. Here, the direction of torque transfer is completely reversed depending on whether the warhead and the finished coal are assembled or disassembled, but the torque is transmitted in the direction that the wide tooth surface of the tooth of the annular latch pushes the stopper for screwing. The point is the same.

In addition, in some sections of the handle, for example, at the rear end of the handle, a grip 18 is formed so that the operator can grip the handle more reliably, through which the operator can more easily torque to the torque transfer socket. Can be delivered.

In the present embodiment, the gripping portion was formed by knurling (string processing).

The handle is also provided with a torque wrench connection hole 20 for use when greater torque is required.

5A and 5B show clearly how the torque wrench connection hole 20 is utilized, and is a photograph showing a state before and after connecting the torque wrench 100 to the circular warhead fastener of the present embodiment. .

As shown in these figures, for example, the engaging projection 101 formed at one end of the torque wrench 100 is fitted into the torque wrench connection hole 20 so that they are securely engaged.

In this way, when the handle and the torque wrench 100 are combined, the same effect as that of the longer handle length occurs. Therefore, based on the lever principle, the operator can transmit a larger torque to the torque transfer socket 13 even with less force.

6 is a photograph showing a state in which the circular warhead fastener according to the present embodiment is coupled with the warhead 200.

When the warhead is inserted into the warhead insertion hole 11 illustrated in FIGS. 5A and 5B, the torque transfer socket 13 is caught at the end portion of the warhead, that is, the portion where the warhead and the finished coal are connected, thereby preventing further movement. At this point, the side groove of the warhead 200 is formed.

In FIG. 6, such side grooves are not visible because they are hidden by the fixing pin 15.
