Description

Technical Field

[0001] The invention relates to the technical field of wire detection, in particular to an aviation wire arc testing device and a testing method thereof. Background Art

[0002] The aviation wire arc test device simulates the arc environment that the wire may encounter in actual operation to detect the anti-destruction ability of the wire insulation layer under the action of the arc. This test is crucial to ensure the safety and reliability of aviation wires.

[0003] Patent publication number CN113960430A discloses an aviation wire arc test device, which drives the blade to reciprocate by setting a wire arc cutting assembly to simulate the damage of the wire caused by the arc caused by mechanical damage during operation, thereby realizing the detection of the arc resistance performance of the aviation wire;

[0004] The above-mentioned test device only simulates the arc resistance performance test of aviation wires through the reciprocating motion of the blade under normal pressure environment. Since aviation wires are usually used in aircraft, when the aircraft encounters extreme weather conditions such as typhoons and tornadoes during flight, the pressure of the aircraft's external environment will increase. When the aircraft is in a high-voltage environment, the high-voltage environment will cause the insulation performance of the aviation wires to deteriorate, which will directly lead to an increased risk of current leakage. Therefore, the above-mentioned test device has low test accuracy for the electrical resistance performance test of aviation wires, resulting in current leakage in the aviation wires in a high-voltage environment, causing a short circuit, resulting in failure of the aircraft's electrical system, affecting the normal operation of the aircraft. Summary of the invention

[0010] The vibration component includes a mounting plate, a moving rod symmetrically arranged on the mounting plate, a guide block arranged on the moving rod, a lifting plate arranged at one end of the moving rod, a lifting groove arranged on the lifting plate, a sliding rod arranged in the lifting groove, and a lifting block arranged in the box body.

[0011] As a preferred solution of the aviation wire arc testing device described in the present invention, the driving assembly includes an eccentric rod, a clamping block arranged at the eccentric position of the eccentric rod, a connecting rod arranged at the end of the moving block away from the plug barrel, and a guide rod arranged on the connecting rod.

[0012] As a preferred solution of the aviation wire arc testing device described in the present invention, it comprises: a bottom block symmetrically arranged on the frame, a buckle 1 arranged in the bottom block, a pressing rod arranged on the buckle 1, a top block arranged on the bottom block, and a buckle 2 arranged on the top block.

[0013] As a preferred solution of the aviation wire arc testing device of the present invention, the mounting tube assembly includes a fixed tube and a plug-in tube plugged into one end of the fixed tube, and two spring pieces are arranged in an array on the fixed tube.

[0014] As a preferred solution of the aviation wire arc testing device of the present invention, there is a horn frame arranged at one end of the rack away from the oblique rod, and a second roller symmetrically arranged on the horn frame.

[0015] To achieve the above object, the present invention provides the following technical solution: a test method for an aviation wire arc test device, comprising the following test method:

[0016] First, pass the aviation wire to be tested through the plug-in tube and the fixed tube in the two clamping parts, and then insert the plug-in tube into the fixed tube. The spring piece 2 gathers toward the aviation wire under the push of the plug-in tube. At this time, the aviation wire will be clamped by the installation tube assembly;

[0017] Then place the mounting tube assembly in the limiting groove in the bottom block, then rotate the top block, insert buckle 2 into the elastic groove, buckle 2 forces buckle 1 to avoid, and when the end faces of the limiting grooves of the top block and the bottom block coincide, the spring sheet 3 will push buckle 1 to limit buckle 2. At this time, the mounting tube assembly will be limited by the top block and the bottom block, and then push the transverse block to make gear 3 rotate to mesh with gear 2. When it is necessary to remove the aviation wire, pull the transverse block to separate gear 2 from gear 3, press the pressing rod to make buckle 1 avoid buckle 2, and manually flip the top block at the same time. At this time, the top block will rotate around the hinge between it and the bottom block as the axis. At this time, the mounting tube assembly can be removed from the bottom block, and the aviation wire can be electrically connected to the power supply.

[0018] Start the motor, the motor output shaft drives the central shaft to rotate, the central shaft drives the eccentric rod to rotate, the eccentric rod drives the clamping block to slide in the key slot 4, and at the same time the eccentric rod pulls the guide rod and the connecting rod, so that the moving block moves linearly back and forth along the moving slot, causing the tool to move synchronously with the moving block and scrape the surface of the aviation wire on the clamping component;

[0019] At the same time, the movement of the moving block will push the opening and closing component through the push rod. When the push rod pushes the opening and closing component to move in the direction of the air intake cylinder, the key slot two and the key slot three coincide with each other, and the two interactive rods of the opening and closing component close to one end of the push rod shrink into the slide slot, and at the same time, the two interactive rods of the opening and closing component away from one end of the push rod extend out of the slide slot. As the opening and closing component assembly moves in the direction of the air intake cylinder, the gas in the plug cylinder enters the interior of the box body, and the two interactive rods of the opening and closing component away from one end of the push rod contact the end of the air intake cylinder inserted into the plug cylinder, and then the interactive rod away from one end of the push rod is pushed by the air intake cylinder to shrink into the slide slot, and at the same time, the roller one will slide along the key slot one, causing the rotating block to rotate in the two fixed blocks. At this time, the positions of the key slot two and the key slot three are gradually misaligned, and at the same time, the two interactive rods close to one end of the push rod extend out of the slide slot.

[0020] When the push rod drives the opening and closing component to move in the direction away from the air inlet cylinder, the movement of the opening and closing component generates negative pressure in the plug cylinder, and the air outside the box enters the plug cylinder through the one-way valve under atmospheric pressure. When the two interactive rods near one end of the push rod come into contact with the baffle, the two interactive rods near one end of the push rod retract into the slide groove, while the two interactive rods far from one end of the push rod extend out of the slide groove, and then the gripping block rotates until the key slot two and key slot three overlap, and the air pressure in the box gradually rises.

[0021] At the same time, during the reciprocating movement of the moving block, the moving block will push the rack to move, and under the action of the oblique rod, the rack will slide in the oblique groove, causing the rack to drive gear one to rotate, and then gear one drives the ejector rod, the plug cylinder, and the opening and closing component to rotate, and then gear two drives gear three to rotate, and gear three drives the installation tube assembly and the aviation wire in the installation tube assembly to rotate, so that the contact area between the tool and the aviation wire increases;

[0022] When the rack moves back and forth along the oblique groove, the two rollers 2 on the horn frame will gradually contact the guide block, thereby forcing the guide block to drive the moving rod and the lifting plate to rise, the spring 1 is deformed and compressed, and the slide bar slides in the key groove 5, causing the lifting block to gradually slide toward the end away from the air intake cylinder, and then the spring 2 is deformed and compressed and pushes the clamping component away from the end of the plug cylinder, causing the distance between the two clamping components to increase. At this time, the aviation wire between the two clamping components will be subjected to a pulling force;

[0023] When roller two moves to separate from the guide block, the moving rod and the lifting plate will drop rapidly under the elastic force of spring one. At this time, under the elastic force of spring one and spring two, the lifting plate and the lifting block will quickly reset and vibrate, thereby causing the clamping parts and aviation wires on the lifting block to vibrate.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. Through the rotation of the eccentric rod, the moving block drives the cutter to reciprocate and scrape the aviation wire, thereby simulating the damage of the arc to the aviation wire and realizing the detection of the arc resistance performance of the aviation wire. At the same time, the interactive rod is used to control the rotation of the rotating block to control the overlap and misalignment of the key slot 2 and the key slot 3, so that the gas pressure in the box gradually increases during the reciprocating movement of the opening and closing components in the plug cylinder, thereby further detecting the arc resistance performance of the aviation wire in a high-pressure environment. Therefore, the detection accuracy of the test device for the electrical resistance performance of the aviation wire is improved, and the risk of leakage of the aviation wire caused by the high-pressure gas environment is reduced, thereby ensuring the stable operation of the electrical system of the aircraft during the flight, and further ensuring the flight safety of the aircraft;

[0026] 2. The moving block drives the rack to move back and forth in the oblique groove, so that gear 1 drives the plug barrel, the plug barrel drives gear 2, gear 2 drives gear 3, and gear 3 drives the aviation wire in the installation tube to rotate, so that the tool can fully contact the insulation layer of the aviation wire, further improving the detection accuracy of the test device for the electrical resistance performance of the aviation wire, reducing the risk of damage to the insulation layer of the aviation wire during the flight of the aircraft, and improving the flight safety of the aircraft;

[0027] 3. By setting a moving rod, the rack drives the horn rack to move, and the contact between the guide block and the second roller is utilized to realize the lifting and lowering of the lifting plate. Under the action of the first spring, the lifting plate will cause the lifting block to vibrate, and at the same time, the lifting plate will drive the lifting block to move. The second spring and the pull rod are utilized to cause the aviation wire to be subjected to vibration and pulling force, which further simulates the external interference to the aviation wire during the flight of the aircraft, thereby improving the detection accuracy of the electrical resistance test of the aviation wire.

[0073] When roller 2 48 moves to separate from guide block 43, under the elastic force of spring 1, moving rod 42 and lifting plate 44 will drop rapidly. Under the elastic force of spring 1 and spring 2, lifting plate 44 and lifting block 46 will reset rapidly and vibrate, thereby causing clamping component 5 and aviation wire on lifting block 46 to vibrate, thereby further simulating the vibration of aircraft during flight, causing displacement of internal structure of aircraft, causing aviation wire to be pulled, and improving the detection accuracy of electrical resistance test of aviation wire.

[0074] The remaining structure is the same as that of Example 2.

[0075] Example 4

[0076] Reference Figure 1-12 , which is a fourth embodiment of the present invention, provides: a test method for an aviation wire arc test device, comprising the following steps:

[0077] S1, first, the aviation wire to be tested is passed through the plug-in tube 58 and the fixed tube 57 in the two clamping components 5, and then the plug-in tube 58 is inserted into the fixed tube 57, and the spring piece 2 is pushed up by the plug-in tube 58 toward the aviation wire, and the aviation wire will be clamped by the installation tube assembly;

[0078] S2, then place the mounting tube assembly in the limiting groove in the bottom block 52, then rotate the top block 55, and insert the second buckle 56 into the elastic groove, and the second buckle 56 forces the first buckle 53 to avoid. When the top block 55 and the end face of the limiting groove of the bottom block 52 coincide with each other, the spring sheet three will push the first buckle 53 to limit the second buckle 56. At this time, the mounting tube assembly will be limited by the top block 55 and the bottom block 52, and then push the transverse block to make the gear three 35 rotate to mesh with the gear two 34. When the aviation wire needs to be removed, pull the transverse block to separate the gear two 34 from the gear three 35, press the pressing rod 54, so that the first buckle 53 avoids the second buckle 56, and manually flip the top block 55 at the same time. At this time, the top block 55 will rotate around the hinge between it and the bottom block 52 as the axis. At this time, the mounting tube assembly can be removed from the bottom block 52, and the aviation wire is electrically connected to the power supply.

[0079] S3, start the motor, the motor output shaft drives the central shaft to rotate, the central shaft drives the eccentric rod 27 to rotate, the eccentric rod 27 drives the clamping block 271 to slide in the key slot 4, and at the same time the eccentric rod 27 pulls the guide rod 29 and the connecting rod 28, so that the moving block 22 moves linearly back and forth along the moving slot, causing the tool 23 to move synchronously with the moving block 22 and scratch the surface of the aviation wire on the clamping component 5;

[0080] S4, at the same time, the movement of the moving block 22 will push the opening and closing component 25 through the push rod 24. When the push rod 24 pushes the opening and closing component 25 to move toward the direction of the air inlet cylinder 11, the key slot 2 and the key slot 3 coincide with each other, and the two interactive rods 255 of the opening and closing component close to the push rod 24 are retracted into the slide slot. At the same time, the two interactive rods 255 of the opening and closing component away from the push rod 24 extend out of the slide slot. As the opening and closing component 25 moves toward the direction of the air inlet cylinder 11, the gas in the plug cylinder 26 is released. The body enters the box body 1, and the two interactive rods 255 at one end away from the push rod 24 in the opening and closing assembly contact with the end of the air inlet cylinder 11 inserted into the plug cylinder 26, and then the interactive rod 255 at one end away from the push rod 24 is pushed by the air inlet cylinder 11 to shrink into the slide groove, and at the same time, the roller 1 slides along the key groove 1, causing the rotating block 252 to rotate in the two fixed blocks 251. At this time, the positions of the key groove 2 and the key groove 3 are gradually misaligned, and at the same time, the two interactive rods 255 near one end of the push rod 24 extend out of the slide groove;

[0081] S5, when the push rod 24 drives the opening and closing component 25 to move in the direction away from the air inlet cylinder 11, the movement of the opening and closing component 25 generates negative pressure in the plug cylinder 26, and the air outside the box 1 enters the plug cylinder 26 through the one-way valve under atmospheric pressure. When the two interactive rods 255 near one end of the push rod 24 contact the baffle, the two interactive rods 255 near one end of the push rod 24 retract into the slide groove, and the two interactive rods 255 away from one end of the push rod 24 extend out of the slide groove, and then the rotating block 252 rotates until the key groove 2 and the key groove 3 overlap, and the air pressure in the box 1 gradually rises;

[0082] S6, at the same time, during the reciprocating movement of the moving block 22, the moving block 22 will push the rack 32 to move, and under the action of the oblique rod 31, the rack 32 will slide in the oblique groove, causing the rack 32 to drive the gear 1 33 to rotate, and then the gear 1 33 drives the push rod 24, the plug cylinder 26, and the opening and closing component 25 to rotate, and then the gear 2 34 drives the gear 3 35 to rotate, and the gear 3 35 drives the installation tube assembly and the aviation wire in the installation tube assembly to rotate, so that the contact area between the tool 23 and the aviation wire is increased;

[0083] S7, when the rack 32 moves back and forth along the oblique groove, the two rollers 2 48 on the horn frame 47 will gradually contact the guide block 43, thereby forcing the guide block 43 to drive the moving rod 42 and the lifting plate 44 to rise, the spring 1 is deformed and compressed, and the slide bar 45 slides in the key groove 5, causing the lifting block 46 to gradually slide toward the end away from the air intake cylinder 11, and then the spring 2 is deformed and compressed and pushes the clamping component 5 away from the end of the plug cylinder 26, causing the distance between the two clamping components 5 to increase. At this time, the aviation wire between the two clamping components 5 will be subjected to a pulling force;

[0084] S8, when roller 2 48 moves to separate from guide block 43, under the elastic force of spring 1, moving rod 42 and lifting plate 44 will drop rapidly, and under the elastic force of spring 1 and spring 2, lifting plate 44 and lifting block 46 will reset rapidly and vibrate, thereby causing clamping part 5 and aviation wire on lifting block 46 to vibrate.
