Description

Gunner's Cap {GUNNER'S QUADRANT}

The present invention relates to a shooter upper limit for correcting the angle of the scope so that the barrel, such as tank, mortar or howitzer can be aimed at the correct angle.

In general, tanks, 60MM, 81MM, and 106MM mortars or howitzers are equipped with barrels, which are the body of a parabola, i. It is very important to adjust the barrel's angle precisely, as the shell's angle of impact depends on the barrel's angle.

For artillery, it is natural that the barrel's angle should be accurately measured and fixed as it is not an exaggeration to say that the bullet is hit with life by adjusting the angle of the gun and adjusting the angle of the barrel. will be.

The sight, which is a scale (site) for adjusting the angle of the barrel, is naturally provided in the gun, and the sight is indicated by the military (MIL) scale. These sights are mechanically or electrically distorted little by little depending on the use of the gun or the passage of time, and errors are bound to occur when aiming.

As described above, the device for correcting the angle of the finely twisted scope so that the gun barrel can be aimed at the correct angle is the limit of the shooter. The gun is provided with a fixed plate to which the shooter upper limit is fixed in parallel with the barrel, and the shooter upper limit is fixed to the fixed plate to correct the error while comparing the origin of the gun and the difference between the sight of the shooter and the limit of the shooter.

1 is a perspective view showing a shooter upper limit according to the prior art, Figure 2 is a plan view showing a blister sensor in the embodiment of FIG.

As shown in FIG. 1, the quadrant limiter according to the related art has a fan-shaped frame 10 having two sides 11 and one arc 12, and a side length direction of the arc 12. Coarse ruler 20 installed along the teeth, teeth 30 formed along the longitudinal direction of the inner surface of the arc 12, and one end of the body 10 to be rotatable about the center of the arc (12) A measurement rod 40 installed inside and provided with an indicator 41 indicating the coarse ruler 20 at the other end so as to slidably engage along the teeth 30, and one end of the measurement rod 40. A fine screw 50 provided with a fine ruler 51 coupled to an upper part to finely adjust the rotation of the measuring rod 40, and installed on an upper portion of the measuring rod 40, It includes a blister sensor 60 for detecting a horizontal state.

The blister sensor 60 fills the solution so that the blister 62 is formed in the cylindrical cylinder 61 installed in the longitudinal direction parallel to the measuring rod 40 so that the blister 62 is centered in the cylindrical cylinder 61. It is a sensor that detects that the horizontal of the measuring rod 40 is made to be placed.

Conventional shooter upper limit of the configuration as described above is fixed to the fixed plate of the gun on the basis of the origin of the first barrel, then leveling the measurement rod 40 through the blister sensor 60, at this time the measurement rod (40) for the origin of the barrel After reading the scale with respect to the origin indicated by the indicator 41 of), it is described. Next, the angle of the barrel is changed through the scope of sight based on the origin of the barrel, and the aim of the barrel is set to 600 millimeters (MIL). At this time, the upper limit of the shooter is also inclined with the fixed plate by the changed angle of the barrel, and the blisters of the blister sensor 60 will be moved at an inclined angle. Since the angle of the barrel is adjusted by the aiming sight, for example, 600 mils (MIL), the angle of the barrel is moved by the measuring rod 40 of the shooter's upper limit. Move about MIL). Thereafter, the microscopic screw 50 is operated to adjust the horizontal state of the measurement rod 40 through the blister sensor 60, and then the value is adjusted when the barrel is aimed at the barrel through the coarse ruler 20 and the fine ruler 51. Read and write. In other words, the actual scale of the barrel is measured by the upper limit of the shooter through the difference between the scale on the origin of the barrel and the sight on the aiming point, and the difference by the difference can be known by comparing the difference between the actual scale and the sight of the gun. Will be. The angle as much as the error can be corrected through reinstallation or replacement or correction of the scope.

However, the shooter upper limit according to the prior art is that the artillery ruler (20) and fine movement ruler (51) need to read and write artillery shooters or adversaries directly, so if you read or write incorrectly, the angle of the barrel will be completely misaligned with the wrong measurement. Can be.

Moreover, even if the reading ruler 20 and fine movement ruler 51 are correctly read and described, the horizontal state of the measurement rod 40 is visually checked and checked according to the movement of the blister 62 of the blister sensor 60. The horizontal state of the measuring rod 40 is not completely reliable, which leads to another error in calibration.

An object of the present invention devised to solve the problems described above, it is possible to easily read and describe by displaying the scale value on the display when measuring the angle of the barrel, it is possible to derive a more accurate measurement value, It is to provide a shooter upper limit that can be reliably leveled so that the calibration of the barrel sight can be more precisely performed.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the quadrant limit according to the present invention.

Shooter upper limit according to the present invention is a device for correcting the angle of the finely twisted scope so that the gun barrel can be aimed at the correct angle, as shown in Figures 3 to 10, the body 100, the teeth 200 , Including the measuring rod 300, fine screw 400, rotary encoder 500, the tilting sensor 600 and the display 700, the on-off switch 800, the display fixing button 910 and release It may further include a button 920.

Body 100 is a fan-shaped frame consisting of two sides 110 and one arc 120, as shown in Figure 3 is made of a copper alloy material that is strong and corrosion-resistant because the various components to be described later attached, combined do. One of the two sides 110 of the body 100 functions as a support plate, and the other side 110 to be unfolded by the length of the arc (120). As the measurement rod 300 to be described later rotates along the arc 120 connecting the two sides 110, the angle of the barrel is measured by the rotation angle of the measurement rod 300.

Dental teeth 200 are formed along the longitudinal direction of the inner surface of the arc 120, as shown in Figure 3, which is the indicator 310 of the measuring rod 300 to be described later is fixed to the teeth (200). While holding the measuring rod 300 while rotating to give a force is configured to be able to overcome the sliding state of the dentition 200 and slide.

As shown in FIG. 3, the measuring rod 300 is installed inside the body 100 so that one end of the measuring rod 300 is rotatable based on the center of the arc 120, and an indicator 310 is provided at the other end thereof. It is slidably engaged along the 200.

The fine screw 400 is coupled to an upper end of the measuring rod 300 as shown in FIG. 3 to finely adjust the rotation of the measuring rod 300. In other words, when holding the measuring rod 300 to give a force to rotate by the angle of the barrel can be rotated to the approximate angle, but it is difficult to precisely operate. Therefore, when the rotation of the measurement rod 300 is finely moved up and down based on the indicator 310 according to the left and right rotation of the fine screw 400, fine angle adjustment can be achieved.

Since the configuration and operation of the above-described body 100, the teeth 200, the measuring rod 300 and the fine thread 400 is the same as in the prior art, a detailed description thereof will be omitted. Hereinafter, the rotary encoder 500, the tilting sensor 600, and the display 700 will be described in detail to measure the more accurate and precise rotation angle of the measurement rod 300 in the above configuration.

The rotary encoder 500 is coupled to one end of the measurement rod 300 as shown in FIGS. 3 to 6 to detect a rotation angle of the measurement rod 300. Since one end of the measurement rod 300 is rotatably installed in the body, the rotary encoder 500 detects the rotation angle of the rotation shaft of one end of the measurement rod 300. The rotary encoder 500 is a device that converts a mechanical rotational displacement (analog) into an electrical pulse (digital), and is useful for measuring and controlling the position, angle, and speed of a mechanical device.

In general, the rotary encoder 500 can be divided into two types, an incremental type and an absolute type. The incremental type is a type that converts a rotation angle of a rotating shaft into an electrical signal proportional thereto and outputs the absolute type. Absolute rotation angle detection type that divides 360 degrees into a certain ratio based on 0 degrees of the rotation axis, designates an electric digital code that can be recognized for each divided angle, and outputs the designated digital code according to the rotation angle of the rotation axis. As the output value is not changed by any electric factor, it does not need to compensate for the origin, and it is also strong against noise. Therefore, in the quadrant limit according to the present invention, since only the absolute rotation angle of the measuring rod 300 is desired, the rotary encoder 500 preferably uses an absolute type.

The tilting sensor 600 is installed on the measuring rod 300 as shown in FIGS. 3 to 6 to detect whether the measuring rod 300 is horizontal. That is, the tilting sensor 600 is a sensor for detecting a tilting degree, that is, a tilting degree as the name, and is also called an inclination angle sensor that detects an inclination angle and converts it into an electrical signal. The tilting sensor 600 includes a differential transformer, a potentiometer, a torque balance sensor, and the like, regardless of which one is used. However, it is more preferable to use a torque balance type tilting sensor that can obtain a small size, light weight, excellent responsiveness, high precision and high resolution.

That is, in the torque balance tilting sensor 600, as shown in FIG. 9, the light receiving elements PTR1 and PTR2 and the resistors R1 and R2 form a DC bridge circuit, and the movable coils L1, L2) and the load resistor R0 are connected, and the light shielding piece S is attached to the front end of the movable element MC connected to the movable coils L1 and L2. When the tilting sensor 600 is fixed in the direction of the center of gravity of the earth GS, the light shielding piece S is positioned at the center of each of the light emitting elements LED1 and LED2 and the light receiving elements PTR1 and PTR2. Since the light receiving elements PTR1 and PTR2 receive the same amount of light from the LED2, respectively, the bridge circuit is balanced. However, if the tilting sensor 600 is inclined by the predetermined angle θ1 with respect to the center of gravity GS of the earth, the movable element MC is also inclined in the same direction, but the predetermined angle θ is due to the moment due to the unbalance of weight. Move in the original direction by '). Therefore, the resistance of the light receiving elements PTR1 and PTR2 changes due to the movement of the light shielding piece S, and the balance of the bridge circuit is broken so that the current I1 flows through the movable coils L1 and L2. At this time, the current I1 becomes the output current of the tilting sensor 400, and the display 700 to be described later receives the output current of the tilting sensor 400 as a signal.

By the tilting sensor 600 as described above, the degree of inclination of the measurement rod 300 can be known as well as the measurement rod 300 can be easily known how inclined.

The display 700 is installed to be exposed to one side of the measurement rod 300 as shown in FIGS. 3 to 7 and receives a signal detected from the rotary encoder 500 to rotate the angle of the measurement rod 300. Denotes a mill (MIL) value, and indicates whether the measurement rod 300 is horizontal by receiving a signal detected from the tilting sensor 600. The millimeter (MIL) value is a finer representation of the 0 to 360 degree angle from the military unit of 0 milliliter (MIL) to 6400 millimeters (MIL). Although not described or indicated in a separate configuration, the display 700 receives a signal from the rotary encoder 500 and the tilting sensor 600, and is equipped with a microcomputer (micom) to convert and display units. It is connected through wiring and has a built-in battery for driving by power.

Since the display 700 cannot always be turned on, the on-off switch 800 is provided to be exposed to one side of the measurement rod 300 to turn on and off the display 700. In addition, as shown in FIG. 7, the rotation angle that changes according to the rotation of the measurement rod 300 may be fixed at a specific angle so that the rotation angle of the measurement rod 300 displayed on the display 700 may be fixed and read. The display fixing button 910 may be further included. The display fixing button 910 is installed to be exposed to one side of the measurement rod 300 is fixed in the pressing operation of the mill (MIL) value of the rotation angle of the measurement rod 300 is displayed on the display 700. That is, when the display fixing button 910 is pressed, the rotation angle of the measurement rod 300 at that time is fixed and displayed on the display 700, and even if the measurement rod 300 rotates, the mill ( The MIL value does not change. Of course, if you want to measure the rotation angle of the measurement rod 300 again, it is necessary to release the display (MIL) value fixed by the display fixing button 910, for this purpose may further include a release button (920) have. The release button 920 is installed to be exposed to one side of the measurement rod 300 to release the fixed mill (MIL) value of the measurement rod 300 by the display fixing button 910. Accordingly, when the release button 920 is pressed, the mill (MIL) value displayed according to the rotation of the measurement rod 300 on the display 700 is changed.

In addition, the display 700 receives the signal sensed from the tilting sensor 600 and also displays whether the measurement rod 300 is horizontal, which is a function of the tilting sensor 600 rather than simply indicating whether it is horizontal or not. It may be more convenient if it can represent the degree of inclination of the measurement rod 300 in order to utilize more. That is, as shown in FIG. 7, the display 700 receives a signal from the tilting sensor 600 to indicate whether the measurement rod 300 is horizontal, but not the graphic image in the shape of the measurement rod 300. The notification information in the case of the dynamic movement, the degree of tilt and the horizontal state can be displayed together. The user may check while more easily adjusting the horizontal of the measurement rod 300 while looking at the screen of the display 700.

As described above, the operation of the shooter's upper limit according to the present invention through the display 700 shown in FIG. 7 will be described with reference to FIGS. 4 to 6.

First, as shown in Fig. 4, the barrel of the gun is in the original position, and the shooter cap according to the present invention is seated on the fixed plate of the gun. Even if the barrel is in the origin, the origin of the current barrel may not be horizontal due to the tilt of the ground or the skew of the barrel. Therefore, after mounting the shooter upper limit on the fixed plate of the gun, while watching the display 700, the measuring rod 300 is leveled by the rotation of the measuring rod 300 and the fine adjustment of the fine screw 400. At this time, the mill (MIL) value displayed on the display 700 in the horizontal state of the measurement rod 300 is the home state measurement value in the home state of the barrel. Of course, by pressing the display fixing button 910 to read and write the home position measurement value and then press the release button 920.

Next, as shown in FIG. 5, the barrel is aimed through the sight and rotated at a specific rotation angle. Accordingly, the upper limit of the shooter is also rotated by the rotation angle of the barrel.

Next, as shown in FIG. 6, the measurement rod 300 is rotated at a specific aimed angle of rotation of the barrel, and then the measurement rod 300 is adjusted by fine adjustment of the fine motion screw 400 while checking whether or not it is horizontal. Level. In the state where the measuring rod 300 is horizontal, the mill (MIL) value displayed on the display 300 becomes a measurement value of the aiming state in the aiming state of the barrel. Of course, even at this time by pressing the display fixing button 910 to read and write the aiming state measurement value.

Through the above process, the specific angle of rotation aimed through the barrel's sight is determined by the aiming angle value, and the angle of rotation of the barrel measured by the shooter's upper limit is the actual rotation by adding or subtracting the measured value of the aiming state and the origin value. It is determined by the value. That is, the difference between the actual rotation value and the aiming mirror value becomes an error, and the corrected sight can be corrected by reinstalling, replacing, or correcting the sighting mirror. For example, if the sight value is 600 mils, the home position measurement is 10 mils, and the normal aiming state measurement is 605 mils, the actual rotation value is 605-10 = 595 mils. Therefore, since the difference between the actual rotation value of 595 millimeters and the aiming mirror value 600 millimeters is 5 millimeters, the aiming mirror may be corrected by 5 millimeters.

As described above, when only one rotation angle of the measurement rod 300 is displayed on the display 700 of the embodiment of FIG. 7, it is cumbersome to continuously read and describe the origin state measurement value and the aiming state measurement value. As shown in FIG. 8, the display 700 may include a current state display unit 710, an origin state display unit 720, a aiming state display unit 730, and a real rotation value display unit 740 to overcome this inconvenience. Can be.

The current state display unit 710 displays a mill (MIL) value, which is a rotation angle that continuously changes as the measurement rod 300 rotates. On the other hand, the home position display unit 720 displays the mill (MIL) value, which is the rotation angle of the measurement rod 300, as the first fixed value, the home state measurement value by first pressing of the display fixing button 910, and aiming. The state display unit 730 displays the mill (MIL) value, which is the rotation angle of the measurement rod 300, as the second fixed value by the second press of the display fixing button 910 as the measured value of the aiming state. At this time, the actual rotation value display unit 740 is the actual rotation value which is a value obtained by adding or subtracting the home position measurement value, which is the first fixed mill value of the home position display unit 720, and the second collimation state measurement value, which is the second millimeter value of the aiming state display unit 730. Is displayed. Therefore, since the actual rotation value is directly derived through the actual rotation value display unit 740, an error can be easily confirmed only by comparing with the aiming mirror value without requiring a separate description.

On the other hand, gunner's cap is a military tool and cannot be operated purely electronically. In other words, having a function as a conventional manual shooter upper limit will be easier to overcome in the event of an emergency. Accordingly, the quadrant limiter according to the present invention has a coarse ruler 125 installed along the lateral longitudinal direction of the arc 120 to implement the conventional manual function as shown in FIG. It may further include a blister sensor 610 is installed on the top to detect the horizontal state of the measurement rod 300, the indicator 310 of the measurement rod 300 instructs the coarse ruler 125, The fine screw 400 may be provided with a fine ruler 410.

The embodiments of the present invention described above and shown in the drawings should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention is limited only by the matters described in the claims, and those skilled in the art will be able to modify the technical idea of the present invention in various forms. Accordingly, such improvements and modifications will fall within the scope of the present invention as long as they are obvious to those skilled in the art.
