Description

Technical Field

[0001] The invention belongs to the technical field of sensor bounce testing, and in particular relates to a small-caliber artillery sensor bounce testing device and a testing method. Background Art

[0002] During the firing process of artillery, the counting waveform collected by the oscilloscope is a rectangular wave, which is an important indicator to measure the normal movement of the artillery mechanism, and is also the only basis for calculating the remaining bullet count.

[0003] The cannon uses the contact counting principle, that is, the counting pulses are generated by the contact movement of mechanical parts and the conduction and disconnection of the corresponding circuits, and are collected by an oscilloscope. The main related parts include the sensor rod component, the sensor seat component, the left and right busbars, the automatic safety, and the left and right front controllers. During the cannon shooting process, the left and right front controllers move up and down alternately, driving the automatic safety to swing back and forth around the electric ignition machine installation axis, and then driving the sensor rod to swing back and forth around the electric ignition machine installation axis, so that the busbar and the sensor rod are alternately connected to form a pulse signal, which is counted once. This reciprocating process generates continuous counting pulses. The counting pulses are rectangular, the cannon mechanism is normal, and the counting waveform shows an abnormal disconnection (no longer a rectangular wave), which is commonly known as a sensor jump failure.

[0004] Sensor beating failure is a fault in the artillery shooting process. At present, sensor beating failure can only be discovered when a fighter jet loses a shell during live-fire shooting or by checking the collected count waveform abnormality during live-fire shooting at the shooting range. If a sensor beating failure occurs at the shooting range, it is necessary to return to the factory to replace the relevant parts and re-inspect the test items; if a sensor beating failure occurs during live-fire shooting of a fighter jet, it may show that the remaining bullets are counted inaccurately, and it may be mistaken that the bullets have been fired when they have not been fired, which may cause unnecessary conflicts. Summary of the invention

[0005] The purpose of the present invention is to solve the technical problem that the sensor bounce failure in the prior art can only be found during the live-fire shooting of the fighter, and to provide a small-caliber artillery sensor bounce test device and test method. After the product is assembled, the counting waveform data is collected to predict the sensor bounce failure, thereby avoiding unnecessary waste during the live-fire shooting process.

[0006] To achieve the above purpose, the technical solution provided by the present invention is:

[0007] A small-caliber artillery sensor jump test device is provided, which includes a power component, a transmission component, a clamping component, a fixing component and a signal acquisition and processing component.

[0009] The power assembly has an output shaft which is mounted on the power assembly bracket and is used to provide power to the transmission assembly.

[0010] The transmission assembly comprises a connecting shaft, a rotating wheel, a transmission rod and a push rod.

[0011] One end surface of the runner is fixedly connected to the output end of the power component through a connecting shaft, and an eccentric column is arranged at the other end surface away from the center of the circle.

[0012] One end of the transmission rod close to the guide rail frame is rotatably connected to the fixed seat and is provided with a fan-shaped gear. The end close to the rotating wheel is provided with a long slot hole that cooperates with the eccentric column, and the eccentric column is in the long slot hole, so that the transmission rod can swing around the rotating connection driven by the eccentric column.

[0013] The push rod is installed on the slide groove along the vertical direction. The lower part of the push rod is provided with a rack meshing with the sector gear, so that the push rod can reciprocate up and down along the slide groove under the drive of the sector gear.

[0014] The clamping assembly is used to fix the electric igniter so that the automatic safety of the electric igniter is located above the push rod; the push rod reciprocates up and down and intermittently contacts the automatic safety, so that the electric igniter generates a pulse signal.

[0015] The signal acquisition and processing components include an oscilloscope, a resistor and a voltage-stabilized power supply, which are used to acquire pulse signals and display them through the oscilloscope.

[0016] Further, the clamping assembly includes a rear support, a latch, a latch pin and a front support;

[0017] The rear support is installed on the top surface of the power component bracket, the lock is installed on the rear support through the lock pin, and cooperates with the rear support to fix the electric igniter. The front support is installed on the top surface of the fixing seat to fix the electric igniter.

[0018] Furthermore, a first guide rail groove and a first mounting hole for mounting a card lock are provided on the top of the rear support, and a second mounting hole for mounting a card lock pin is provided on the side of the rear support;

[0019] The lock is a cylinder with a hollow interior and a groove on the outer wall. A lock spring is installed inside the lock. The lock pin is installed in the second mounting hole and the head of the lock pin abuts against the groove so that the lock can be compressed and popped out in the mounting hole; a second guide rail groove is provided on the top surface of the rear support.

[0020] Furthermore, the rear support and the front support are on the same horizontal line, and the latch is located at the center line of the second guide rail groove.

[0021] Furthermore, the height of the automatic safety can be adjusted by changing the meshing point between the sector gear and the rack.

[0022] Furthermore, the connecting shaft is assembled on the power component bracket through a retaining ring and a bearing, and one end of the transmission rod close to the guide rail frame is rotatably connected to the fixed seat through an axle pin.

[0023] Furthermore, the swing angle of the transmission rod is 30° to 40°.

[0024] A small-caliber artillery sensor jump test method is also provided, which is applied to a test device, and the test method comprises the following steps:

[0025] Step 1: Assemble the test device, fix the electric ignition machine on the clamping assembly, and make the automatic safety of the electric ignition machine be located above the ejector rod;

[0026] Step 2: Connect the signal acquisition and processing component to the electric ignition machine to form a test loop;

[0027] Step 3: Start the power assembly to drive the transmission assembly to simulate the mechanical movement of the artillery;

[0028] Step 4: Adjust the speed of the power assembly to 3000-3400 rpm to simulate the firing rate of the artillery;

[0029] Step 5: The power component runs continuously for 5 minutes at the speed in step 4, and the signal acquisition and processing component is used to collect the counting waveform data; if the counting waveform is a rectangular wave, the test is ended; if the counting waveform is not a rectangular wave, the sensor is faulty and needs to be repaired and then repeat steps 1 to 5 for testing.

[0030] Furthermore, in step 2, the oscilloscope is connected in parallel with the electric igniter, and the resistor and the voltage-stabilized power supply are connected in series with the electric igniter.

[0031] The advantages of the present invention are:

[0032] 1. The present invention utilizes the movement of the transmission assembly to simulate the mechanical action of the front controller of the artillery pushing the sensor rod of the electric igniter. After the electric igniter of the artillery is assembled, it can be determined whether the sensor of the electric igniter of the artillery works normally, eliminating the disadvantage that the artillery can only be found in the live ammunition shooting at the shooting range or when the fire failure occurs on the fighter.

[0033] 2. The test device and test method designed by the present invention only need to simply clamp the artillery electric ignition machine, connect the test device circuit, and set the rotation speed for measurement. It is simple and easy to operate, and the measurement results are intuitive and convenient.

[0034] 3. For the artillery that was originally returned to the factory for repair, if the sensor bounced during live-fire shooting failed, it had to be returned to the factory for repair and live-fire shooting tests had to be repeated, which cost a lot of manpower and material resources and had a long maintenance cycle. After adopting this test device, it is only necessary to collect counting waveform data after the product is assembled, which can effectively predict the sensor bounce failure, saving 5,000 yuan for each artillery piece and shortening the cycle to 15 to 30 days. While greatly reducing costs, it also provides a solid technical guarantee for the continuous generation of combat effectiveness at the combat site. BRIEF DESCRIPTION OF THE DRAWINGS

[0067] The signal acquisition and processing component is used to acquire the pulse signal of the test device, and includes an oscilloscope 21 , a 1KΩ resistor 18 and a voltage-stabilized power supply 19 .

[0068] A small-caliber artillery sensor jump test method is applied to a test device, and the test method comprises the following steps:

[0069] Step 1: Assemble the test device, fix the electric igniter 22 in the first guide groove of the front support 5 and the second guide groove of the rear support 2 in the clamping assembly, and limit it with the lock 3 so that the automatic safety of the electric igniter 22 is located above the top rod 13; the height of the top rod 13 lifting the automatic safety is determined by the meshing point of the sector gear and the rack 12.

[0070] Step 2: Connect the signal acquisition and processing component to the electric igniter 22 to form a test loop; the oscilloscope 21 is connected in parallel with the electric igniter 22, and the resistor 18 and the voltage-stabilized power supply 19 are connected in series with the electric igniter 22.

[0071] Specifically, a 1KΩ resistor 18 is connected in series to the 3# pin 23 and the 4# pin 24 of the electric igniter 22, an oscilloscope 21 is connected in parallel to the 3# pin 23 and the 4# pin 24, and the other end of the 1KΩ resistor 18 is connected to the voltage-stabilized power supply 19, that is, the voltage-stabilized power supply 19, the 1KΩ resistor 18, the electric igniter 22, and the oscilloscope 21 form a test circuit loop, such as Figure 6 As shown. Among them, the 3# pin 23 and the 4# pin 24 are directly connected to the test end of the sensor rod of the electric igniter 22 through wires and rivets, and are used to test the signal of the counting waveform of the oscilloscope 21; the 1KΩ resistor 18 is used to limit the circuit current to prevent the positive and negative poles of the circuit from being short-circuited without load. Plug the power plug of the voltage-stabilized power supply 19 into the 220V socket, and plug the power plug of the oscilloscope 21 into the 220V socket. Connect the power line and feedback line plugs of the servo motor 1 to the sockets of the AC servo driver 20 respectively, press the start button of the AC servo driver 20, adjust the speed to 500 rpm, and plug the power cord of the AC servo driver 20 into the 220V socket. Press the start switch of the oscilloscope 21 to debug the oscilloscope 21 in the voltage test interface. Preparation is complete.

[0072] Step 3: Start the 220V socket button, the servo motor 1 rotates, driving the transmission assembly to run, simulating the mechanical movement of the artillery.

[0073] Specifically, the servo motor 1 rotates, driving the rotating wheel 8 to rotate. The eccentric column of the rotating wheel 8 slides in the long groove of the transmission rod 11, so that the transmission rod 11 rotates around the axle pin, driving the fan gear at one end of the transmission rod 11 to swing within a range of 30°, and the meshing rack 12 moves up and down on the guide frame 16. The top rod 13 fastened with the rack 12 acts on the automatic safety of the electric ignition machine 22, simulating the mechanical movement of the artillery.

[0074] Step 4: The mechanical movement of the artillery is normal, turn off the power socket button, adjust the AC servo driver 20 start button, adjust the speed to 3000 rpm, simulate the firing rate of the artillery. Start the power button.

[0075] Step 5: The servo motor 1 runs continuously for 5 minutes at the speed in step 4, and the signal acquisition and processing component is used to collect the counting waveform data; if the counting waveform is a rectangular wave, the test is terminated, the sensor components in the electric igniter 22 are good, and the live-fire shooting test can be carried out normally; if the counting waveform is not a rectangular wave, the sensor is faulty and needs to be repaired and then repeat steps 1 to 5 for testing.

[0076] Step 6: After the test is completed, turn off the power socket button, unplug the power plug of the voltage stabilizer 19 and the power cord plug of the AC servo driver 20 from the 220V socket in turn. Remove the 1KΩ resistor 18 and the oscilloscope 21 from the 3# pin 23 and 4# pin 24 of the electric igniter 22 in turn. Press the locking pin 4 with a punch, push the electric igniter 22 in the direction of the locking pin 4, and remove the electric igniter 22.

[0077] Unplug the power line and feedback line of the servo motor 1 from the socket of the AC servo driver 20. Remove the other end of the 1KΩ resistor 18 from the voltage-stabilized power supply 19, and unplug the power plug of the oscilloscope 21 from the 220V socket. Arrange the power components.
