The present invention relates to a fuse signal detecting apparatus using a light source and a reflector for checking and checking the function of the proximity fuse used in the shell, that is, whether the loading time and the loading speed are normally operated.

The present invention can be tested under the conditions of testing 52.6-l58m Sec, 5700 RPM, which is the standard of the proximity fuse, that is, 111-600m Sec, 15000-2700 RPM, but especially under conditions similar to the rotational speed generated when the shell is flying. It adopts the device that transmits the optical energy by the optical cable which is the contactless energy transmission method, and it can be transmitted regardless of the rotation.

The present invention uses a contactless energy transmission method, so that the sensing point of the proximity fuse also uses a portion of the side of the gunpowder assembly hole to block the transmission and transmission of light transmitted when the rotor rotates. Noise generated by the rotation of the rotating body at high speed can be removed by embedding electronic circuit in the aluminum case.When detecting the fuse signal, the light emitted from the light source is scattered by the circular reflector and the optical cable on the rotating body When passing through the sensing point (Sensing Point) of the access fuse is passed to the optical cable side of the fixture is a device that can measure the loading time and the loading speed by a specific device.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is an overall cross-sectional view of a fuse signal detecting apparatus according to the present invention.

In the lower part of the test column 1, an speed increasing apparatus 2 capable of rotating the speed of rotation at a speed of 25000 RPM or higher is mounted, and the rotating shaft 3 of the speed increasing apparatus 2 is formed by upper and lower beams to have a corresponding shape. The lower end of the rotating body 4 is inserted and fixed, but the rotating body 4 is integrated by screwing the upper rotating body 5 and the lower rotating body 6 together. The upper rotary body 5 formed a built-in chamber 7 of an adjacent fuse inside and spoke the optical cable 11 starting at the same horizontal line as the required reflector to one lower end of the built-in chamber 7.

형으로 구비하여 상부회전동체(5) 의 광케이블(11)을 통하여 전송되는 광을 전송할 수 있도록 하였다.The upper portion of the interior chamber 7 is screwed into a fixture cover 9 having a pad 8 at the bottom and a cap nut 10 supporting the fixture cover 9. Fixing and fixing the fixture cover 9 as a nut 22 in the upper side, the optical cable 11-1 from the side of the interior chamber 7 extending with the optical cable 11 to the center of the fixture cover 9 of

It was provided in the form to be able to transmit the light transmitted through the optical cable 11 of the upper rotary body (5).

In the upper portion of the rotating body 4, the cable holder 13 once condensed on the upper side of the support rod 12 placed on one side of the rotating body 4 can be varied, but the fixture in the cable holder 13 An optical transmission cable 14 positioned on the same vertical line as the optical cable 11-1 of the cover 9 was provided, and a handle 15 was mounted on the front thereof.

In addition, a fixture 18 having a support 17 provided with a demand-shaped reflector 16 fixed to the support section 12 on a horizontal outer side corresponding to the front end of the optical cable 11 in which the upper rotary body 5 is built. ) Is fixed by a fixing means such as a bolt.

As shown in FIG. 2, the support 17 has a light emitting diode 20 having a vane type at different diverging angles to emit light to the reflector 10. Each light emitting diode 20 Is supplied with a voltage from the power source E as shown in FIG.

In addition, the light transmitted through the optical transmission cable 14 is detected by the circuit system as shown in FIG. 5, and the light received by the photodetector 21 is amplified by the transistor thereof and thus the variable resistor ( VR ₁ ) is detected by comparing with the variable set value of comparator (OP ₁ ) and detected by comparing the resistance value set by resistors R ₁ and R ₂ with comparator (OP ₂ ). Will be

Reference numeral 23 has a fixing pin of the fuse.

Referring to the operation and effects of the present invention as described above are as follows.

Grab the handle 15 of the cable holder 13 located on the upper part of the rotating body 4 and turn it upward. Then, loosen the nut 22 and the cap nut 10 to open the peel cover 9, and test Insert the proximal fuse into the interior chamber 7 and fix it to the positioning pin 23 protruding from the bottom of the interior chamber 7 in the hole drilled in the front of the proximity fuse. 11) It will close between (11-1).

After mounting the access fuse, the fixture cover 9, the cap nut 10, and the nut 22, which are opened, are sequentially assembled and fixed. Then, lower the cable holder 13 to its original position and then apply power. One end of the power source E emits the light emitting diodes 20 via a resistor 19, and the light emission is scattered throughout the required reflector 16. When other power is applied in this state, the rotating body 4 is rotated by the speed increasing device 2, and the rotation speed thereof rapidly increases and rotates at a high speed up to about 2500 RPM or more. ) The detention state is released and the vibrator oscillates left and right.

When the vibrator normally vibrates left and right, the light emitted from the light-emitting diode 20, which is turned on, is transmitted to the optical cable 11 through the optical cable 11 installed in the upper rotating body 5 and in the open / closed state of the vibrator. Accordingly, the process of supplying and blocking light to the optical cable 11-1 is repeated.

Light transmitted to the optical cable 11-1 is applied to the electronic system as shown in FIG. 5 through the optical transmission cable 14. At this time, since the rotating body 4 continues to rotate at a high speed, the light emitted from the light emitting diodes 20 is scattered at all positions of the reflector 16 to maintain the same state that the light is completely emitted. 5) When the optical cable 11 rotates, the optical cable 11 receives light at any part of 360 °, and the vibrator of the access fuse vibrates several times per second, so that the light received by the optical cable 11 is intermittently intermittently. To 1).

The light transmitted to the optical cable 11-1 is transferred back to the optical transmission cable 14 and applied to the photodetector 21 as shown in FIG.

The light receiving portion of the photodetector 21 conducts and widens by the light transmitted from the optical transmission cable 14. The amplified value is compared with the reference value set by the variable resistor VR ₁ in the comparator OP ₁ and applied to the comparator OP ₂ when the value is greater than or equal to the set value. The value below the set value may be generated in the photodetector 21. At the time, the comparison in the comparator OP ₁ is not made.

This phenomenon means that the vibrator of the access fuse is abnormally operated. In the end, the access fuse is judged to be defective and should be repaired by replacing the vibrator.

On the other hand, in the normal case, the voltage from the amplifier OP ₁ is compared with the reference set value consisting of the resistors R ₁ and R ₂ again in the comparator OP ₂ and applied to a predetermined measuring device. It can be recognized that it vibrates smoothly but not normally, and this also requires repair of the access fuse. When a voltage is applied to a predetermined measuring device in the comparator (OP ₂ ), it is possible to measure the operating time of the access fuse, that is, the loading time and the loading speed of the vibrator vibrated. Such measurement can be easily displayed by the display unit. Make sure to check.

As described above, according to the present invention, since the optical cable transmission method, which is a non-contact energy transmission method, is adopted, the loading time and the loading rotation due to the rotor rotation using the vibration of the vibrator of the proximity fuse in a state irrelevant to the high speed rotation of the access fuse. It is possible to measure the head, its configuration is easy to operate and there is no fear of breakdown during use, and in particular, the above-mentioned process of loading time and loading speed Accurate measurement can provide a better access fuse.
