Description

Technical Field

[0001] The present invention relates to the technical field of measuring tooling, and particularly to an aircraft part detection device. Background Art

[0002] The detection of aircraft parts is of crucial importance as these parts directly affect flight safety and the overall performance of the aircraft. In order to ensure that aircraft parts meet the highest quality standards during design, manufacturing, and use.

[0003] The patent with the patent publication number CN218823727U relates to a precision part detection device, belonging to the technical field of precision parts. The key points of its technical solution include a Rockwell hardness tester. A fixing plate is fixedly connected to the top of the Rockwell hardness tester. A protection mechanism is arranged on the front side of the Rockwell hardness tester. There are two pieces of tempered glass on the front side of the Rockwell hardness tester, which solves the problem that the existing Rockwell hardness tester applies pressure to precision parts and observes the hardness of precision parts through data, and the Rockwell hardness tester does not have a protection structure. When testing the hardness of precision parts by applying pressure, if the hardness of the precision part being tested is unqualified, this precision part will break, and the broken precision part will splash forward and to both sides, which is extremely likely to cause harm to the tester and there are certain safety hazards, thus affecting the use effect.

[0004] In the above patent, it has the effect of improving measurement safety. By arranging a protection mechanism on the front side of the Rockwell hardness tester, it can effectively prevent the broken precision parts from causing harm to the tester during the splashing process. However, during the actual detection of aircraft parts, it is still necessary to strictly inspect their surfaces to avoid defects such as depressions, scratches, or microcracks on the part surface caused by excessive detection pressure or improper operation. These surface damages will affect the structural integrity of the part, thereby reducing its fatigue strength and service life, and even posing potential flight safety hazards. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides an aircraft part detection device, which solves the problems raised in the above background art.

[0006] To achieve the above object, the present invention is realized by the following technical solutions: An aircraft part detection device includes a base, a fixing frame is fixedly installed on the top of the base, a scale is fixedly installed on the surface of the fixing frame, and a detection device is further included; wherein, the detection device includes a carrying frame, a lifting plate, a first spring and an arrow. The lifting plate squeezes the first spring during movement, and the first spring deforms under the extrusion. The carrying frame is fixedly installed on the top of the fixing frame. The lifting plate is slidably installed on the circumferential surface of the carrying frame, and the lifting plate is slidably installed on the surface of the fixing frame. The first spring is arranged between the lifting plate and the carrying frame. The arrow is fixedly installed on the side of the lifting plate close to the scale, and the arrow contacts the surface of the scale. The operator observes the position of the arrow and the scale and records the height of the part.

[0007] According to the above technical solution, a rotating rod is threadedly connected to the surface of the lifting plate. A C-shaped plate is slidably installed on the inner wall of the lifting plate. A elastic sheet is arranged between the C-shaped plate and the lifting plate. The rotating rod contacts the side of the C-shaped plate away from the lifting plate. A limiting groove is opened on the side of the fixing frame close to the C-shaped plate. A toothed groove is opened on the side of the C-shaped plate close to the limiting groove. The toothed groove of the C-shaped plate contacts the limiting groove during movement, so that the C-shaped plate is limited and cannot move up and down.

[0008] According to the above technical solution, a support rod is fixedly installed on the side of the lifting plate away from the rotating rod. Infrared light detectors are fixedly installed on both sides of the fixing frame. The two infrared light detectors are symmetrically arranged. The infrared light detector is used to monitor and feedback data on the surface integrity of aircraft parts in real time. A sliding groove is opened on the side of the fixing frame close to the support rod. The support rod contacts the inner wall of the sliding groove. When the support rod moves, the fixing frame provides necessary support for the support rod through the sliding groove.

[0009] According to the above technical solution, a protection device for improving the stability of the lifting plate and a buffer device for ensuring the safety of the lifting plate during reset are arranged on the fixing frame. The protection device includes a carrying rod, a support frame, two T-shaped rods and a protection rod. The movement of the T-shaped rod drives the protection rod to move upward, ensuring that the protection rod is always above the center line of the inspected part. The carrying rod is fixedly installed on the surface of the fixing frame. The support frame is slidably installed on the circumferential surface of the carrying rod. The two T-shaped rods are rotatably installed on both sides of the support frame away from the lifting plate. The protection rod is fixedly installed on the side of the T-shaped rod close to the lifting plate. The inner wall of the support frame contacts the fixing frame. A round hole is opened on the side of the support frame close to the support rod. The support rod contacts the inner wall of the round hole. The movement of the support rod drives the support frame to move upward, and the support frame provides additional support for the support rod during movement.

[0010] According to the above technical solution, a rectangular block is fixedly installed on the inner wall of the support frame, a push block is slidably installed on the surface of the support frame, a second spring is arranged between the push block and the rectangular block, and the push block squeezes the second spring during movement, and the second spring deforms under the extrusion. A round rod is fixedly installed on the top of the push block, a contact plate is fixedly installed on the side of the support frame away from the lifting plate, and a circular groove is formed on the side of the T-shaped rod away from the protection rod, and the size of the circular groove is adapted to that of the round rod.

[0011] According to the above technical solution, a first scroll spring is arranged between the T-shaped rod and the support frame, and the T-shaped rod stretches the first scroll spring during rotation, and the first scroll spring deforms under the tension. An arc surface is formed on the side of the contact plate away from the support frame.

[0012] According to the above technical solution, the buffer device includes an adapter frame, a hollow tube, a cross rod, a sliding rod, a third spring, a portal frame and a rotating plate. The arc surface of the contact plate contacts the bottom of the rotating plate during movement, and the movement of the contact plate drives the rotating plate to rotate upward. The adapter frame is fixedly installed on the side of the fixed frame close to the carrying rod, the hollow tube is fixedly installed on the inner wall of the adapter frame, the cross rod is slidably installed on the inner wall of the hollow tube, the sliding rod is fixedly installed at the bottom of the cross rod, and the sliding rod is slidably installed on the inner wall of the hollow tube. The third spring is arranged between the cross rod and the hollow tube. The portal frame is fixedly installed at the bottom of the sliding rod, and the rotating plate is rotatably installed on the inner wall of the portal frame. The bottom of the rotating plate contacts the bottom of the inner wall of the portal frame. The movement of the contact plate contacts the top of the rotating plate, so that the movement of the contact plate drives the rotating plate to move downward.

[0013] According to the above technical solution, the rotating plate itself has elasticity, and a second scroll spring is arranged between the rotating plate and the portal frame. The rotating plate stretches the second scroll spring during rotation. When the contact plate is separated from the rotating plate, the deformed second scroll spring restores to drive the rotating plate to reset.

[0014] The present invention provides an aircraft part detection device. It has the following beneficial effects:

[0015] (1) For this aircraft part detection device, the first spring exerts a reaction force on the lifting plate, causing the lifting plate to exert a downward pressure on the part. The pressure exerted by the lifting plate is adjusted according to the height of the part, ensuring that the lifting plate can provide stable pressure for parts of different heights and ensuring the accuracy of height inspection. At the same time, the thrust exerted by the rotating rod on the C-shaped plate gradually increases, causing the toothed groove to be in close contact with the limiting groove. By rotating the rotating rod, the operator can quickly limit the lifting plate, thus facilitating the inspection of aircraft parts of the same specification and ensuring that the aircraft parts do not accidentally shake during the operation of the infrared light detector, which may affect the scanning accuracy. The infrared light detector can detect the integrity of the appearance of the aircraft part, avoiding defects in the appearance of the aircraft part and providing guarantee for subsequent production.

[0016] (2) For this aircraft part detection device, the support frame provides additional support for the support rod during movement. By providing additional support for the support rod through the support frame, it ensures that the part remains stable during inspection. At the same time, the protection rod moves synchronously with the support rod, which can guarantee the safety of the part during inspection. Also, the round rod contacts the inner wall of the circular groove during movement. Through standardized operation, the operator can quickly store the protection rod and flexibly choose whether to enable the protection rod according to actual usage requirements.

[0017] (3) For this aircraft part detection device, the third spring exerts a reaction force on the cross rod, causing the rotating plate to exert additional resistance on the contact plate. By the rotating plate exerting additional resistance on the downward moving contact plate, it effectively prevents the lifting plate from colliding during rapid reset, thus ensuring that the lifting plate can safely and smoothly reset to the initial position. At the same time, the surface where the contact plate contacts the deformed rotating plate quickly separates. By setting the elastic rotating plate, the rotating plate can quickly separate from the contact plate during deformation, thus ensuring that the rotating plate can quickly reset to prepare for the next inspection.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1 - 7 , an embodiment of the present invention is: an aircraft part detection device, including a base 1, a fixed frame 2 is fixedly installed on the top of the base 1, a scale 3 is fixedly installed on the surface of the fixed frame 2, and a detection device is further included; wherein, the detection device includes a carrier frame 4, a lifting plate 5, a first spring 6 and an arrow 7, the carrier frame 4 is fixedly installed on the top of the fixed frame 2, the lifting plate 5 is slidably installed on the circumferential surface of the carrier frame 4, the lifting plate 5 is slidably installed on the surface of the fixed frame 2, the first spring 6 is arranged between the lifting plate 5 and the carrier frame 4, the arrow 7 is fixedly installed on the side of the lifting plate 5 close to the scale 3, and the arrow 7 is in contact with the surface of the scale 3. The pressure applied by the lifting plate 5 is adjusted according to the change of the part height, ensuring that the lifting plate 5 can provide stable pressure for parts of different heights.

[0028] A rotating rod 8 is threadedly connected to the surface of the lifting plate 5, a C-shaped plate 9 is slidably installed on the inner wall of the lifting plate 5, an elastic sheet 10 is arranged between the C-shaped plate 9 and the lifting plate 5, the rotating rod 8 is in contact with the side of the C-shaped plate 9 away from the lifting plate 5, a limiting groove is opened on the side of the fixed frame 2 close to the C-shaped plate 9, and a toothed groove is opened on the side of the C-shaped plate 9 close to the limiting groove. By rotating the rotating rod 8, the operator can quickly apply a limit to the lifting plate 5, thereby facilitating the inspection of aircraft parts of the same specification.

[0029] One side of the lifting plate 5 away from the rotating rod 8 is fixedly installed with a support rod 11. Infrared light detectors 12 are fixedly installed on both sides of the fixed frame 2. The two infrared light detectors 12 are symmetrically arranged. A sliding groove is formed on the side of the fixed frame 2 close to the support rod 11. The support rod 11 contacts the inner wall of the sliding groove. By providing the sliding groove, necessary support force is provided for the support rod 11, which helps to improve the stability of the movement of the lifting plate 5.

[0030] During the operation of this embodiment, manually control the lifting plate 5 to move upward. The movement of the lifting plate 5 drives the arrow 7 and the support rod 11 to move upward together. At the same time, the lifting plate 5 squeezes the first spring 6 during the movement, and the first spring 6 deforms under the extrusion. After the lifting plate 5 moves to the predetermined position, place the part on the top of the base 1, and then release the lifting plate 5, so that the deformed first spring 6 restores and drives the lifting plate 5 to move downward. The movement of the lifting plate 5 drives the arrow 7 to move downward. When the lifting plate 5 contacts the top of the part during the movement, the lifting plate 5 is blocked and stops moving. At this time, the first spring 6 that has not been fully restored exerts a reaction force on the lifting plate 5, so that the lifting plate 5 exerts a downward pressure on the part to ensure that the part is in close contact with the lifting plate 5. Then the operator observes the positions of the arrow 7 and the scale 3 and records the height of the part. Then start the infrared light detector 12. The infrared light detector 12 detects through infrared light. The infrared light detector 12 performs real-time scanning on the stationary part and feeds back the data obtained after scanning to the operator. The infrared light detector 12 is used to monitor and feedback the data of the surface integrity of the aircraft part in real time to avoid defects in the appearance of the aircraft part. The pressure exerted by the lifting plate 5 is adjusted according to the change of the part height to ensure that the lifting plate 5 can provide stable pressure for parts of different heights, ensuring the accuracy of height inspection. After the recording is completed, the operator rotates the rotating rod 8 clockwise, so that the rotating rod 8 moves towards the lifting plate 5. The movement of the rotating rod 8 drives the C-shaped plate 9 to move towards the lifting plate 5. The C-shaped plate 9 squeezes the elastic piece 10 during the movement, and the elastic piece 10 deforms under the extrusion. At the same time, the toothed groove of the C-shaped plate 9 contacts the limiting groove during the movement, so that the C-shaped plate 9 is limited and cannot move up and down. The thrust exerted on the C-shaped plate 9 by the continuous movement of the rotating rod 8 gradually increases, so that the toothed groove is in close contact with the limiting groove. At this time, the operator can take out the inspected part and place the parts of the same specification on the top of the base 1 for height inspection. By rotating the rotating rod 8, the operator can quickly limit the lifting plate 5, which provides convenience for the inspection of aircraft parts of the same specification, effectively improving the overall inspection efficiency and providing guarantee for subsequent production.

[0031] Please refer to Figures 1 - 7, on the basis of the above embodiments, in another embodiment of the present invention, a protection device for improving the stability of the lifting plate 5 and a buffer device for ensuring the safety of the reset of the lifting plate 5 are provided on the fixing frame 2; the protection device includes a carrying rod 121, a support frame 122, two T-shaped rods 123 and a protection rod 124. The carrying rod 121 is fixedly installed on the surface of the fixing frame 2, the support frame 122 is slidably installed on the circumferential surface of the carrying rod 121, the two T-shaped rods 123 are rotatably installed on both sides of the support frame 122 away from the lifting plate 5, the protection rod 124 is fixedly installed on the side of the T-shaped rod 123 close to the lifting plate 5, the inner wall of the support frame 122 contacts the fixing frame 2, a round hole is opened on the side of the support frame 122 close to the support rod 11, and the support rod 11 contacts the inner wall of the round hole. The support frame 122 provides additional support for the support rod 11 to ensure that the parts remain stable during inspection.

[0032] A rectangular block 125 is fixedly installed on the inner wall of the support frame 122, a push block 126 is slidably installed on the surface of the support frame 122, a second spring 127 is arranged between the push block 126 and the rectangular block 125, a round rod 128 is fixedly installed on the top of the push block 126, a contact plate 129 is fixedly installed on the side of the support frame 122 away from the lifting plate 5, a circular groove is opened on the side of the T-shaped rod 123 away from the protection rod 124, and the size of the circular groove is adapted to that of the round rod 128. By synchronously moving the protection rod 124 and the support rod 11, the safety of the parts during inspection can be ensured.

[0033] A first scroll spring is arranged between the T-shaped rod 123 and the support frame 122, and an arc surface is opened on the side of the contact plate 129 away from the support frame 122. Through standardized operations, the operator can quickly store the protection rod 124 and flexibly choose whether to enable the protection rod 124 according to actual usage requirements.

[0034] The buffer device includes a connecting frame 131, a hollow tube 132, a cross rod 133, a sliding rod 134, a third spring 135, a portal frame 136 and a rotating plate 137. The connecting frame 131 is fixedly installed on the side of the fixing frame 2 close to the carrying rod 121, the hollow tube 132 is fixedly installed on the inner wall of the connecting frame 131, the cross rod 133 is slidably installed on the inner wall of the hollow tube 132, the sliding rod 134 is fixedly installed at the bottom of the cross rod 133, the sliding rod 134 and the inner wall of the hollow tube 132 are slidably installed, the third spring 135 is arranged between the cross rod 133 and the hollow tube 132, the portal frame 136 is fixedly installed at the bottom of the sliding rod 134, the rotating plate 137 is rotatably installed on the inner wall of the portal frame 136, and the bottom of the rotating plate 137 contacts the bottom of the inner wall of the portal frame 136. By applying additional resistance to the downward moving contact plate 129 through the rotating plate 137, it effectively prevents the lifting plate 5 from colliding during rapid reset, thereby ensuring that the lifting plate 5 can safely reset to the initial position.

[0035] The rotating plate 137 itself has elasticity. A second scroll spring is provided between the rotating plate 137 and the U-shaped frame 136. By providing the elastic rotating plate 137, the rotating plate 137 can be quickly separated from the contact plate 129 during deformation, so as to ensure that the rotating plate 137 can quickly reset and prepare for the next inspection.

[0036] During the operation of this embodiment, when the support rod 11 moves, the fixed frame 2 provides necessary support for the support rod 11 through the chute. At the same time, the movement of the support rod 11 drives the support frame 122 to move upward. The support frame 122 provides additional support for the support rod 11 during the movement to ensure that the lifting plate 5 and the part are more stable when they come into contact. The movement of the support frame 122 drives the T-shaped rod 123 and the contact plate 129 to move upward together. The movement of the T-shaped rod 123 drives the protection rod 124 to move upward to ensure that the protection rod 124 is always above the center line of the inspected part. By providing additional support for the support rod 11 through the support frame 122, it is ensured that the part remains stable during inspection. At the same time, the synchronous movement of the protection rod 124 and the support rod 11 can guarantee the safety of the part during inspection. When it is necessary to open the protection rod 124, first pull the push block 126 downward. The movement of the push block 126 drives the round rod 128 downward. At the same time, the push block 126 squeezes the second spring 127 during the movement, and the second spring 127 deforms under the extrusion. When the push block 126 moves to the designated position, rotate the protection rod 124 in the direction of the carrying rod 121. The rotation of the protection rod 124 drives the T-shaped rod 123 to rotate in the direction of the carrying rod 121. The T-shaped rod 123 stretches the first scroll spring during the rotation. When the T-shaped rod 123 rotates to the designated position, release the push block 126, so that the deformed second spring 127 restores and drives the push block 126 to move upward. The movement of the push block 126 drives the round rod 128 to move upward. The round rod 128 contacts the inner wall of the circular groove during the movement, so that the restoration of the deformed first scroll spring is restricted. Through standardized operations, the operator can quickly store the protection rod 124 and flexibly choose whether to enable the protection rod 124 according to actual usage requirements;

[0037] The arc surface of the contact plate 129 contacts the bottom of the rotating plate 137 during movement. The movement of the contact plate 129 drives the rotating plate 137 to rotate upward. The rotation of the rotating plate 137 stretches the second scroll spring. When the contact plate 129 separates from the rotating plate 137, the deformed second scroll spring restores and drives the rotating plate 137 to reset. After the inspection, the operator rotates the lever 8 counterclockwise to release the limit on the C-shaped plate 9, causing the C-shaped plate 9 to reset and drive the support rod 11 to move downward. The movement of the support rod 11 drives the support frame 122 to move downward. The movement of the support frame 122 drives the contact plate 129 to move downward. The movement of the contact plate 129 contacts the top of the rotating plate 137, causing the contact plate 129 to move and drive the rotating plate 137 to move downward. The movement of the rotating plate 137 drives the portal frame 136 to move downward. The movement of the portal frame 136 drives the sliding rod 134 to move downward. The movement of the sliding rod 134 drives the cross rod 133 to move downward. The cross rod 133 moves and compresses the third spring 135. The deformed third spring 135 exerts a reaction force on the cross rod 133, causing the rotating plate 137 to exert an additional resistance on the contact plate 129. The speed of the downward movement of the contact plate 129 is slowed down by the additional resistance. By applying an additional resistance to the downward-moving contact plate 129 through the rotating plate 137, it effectively prevents the lifting plate 5 from colliding during rapid reset, thus ensuring that the lifting plate 5 can safely and smoothly reset to the initial position. When the bottom of the cross rod 133 contacts the connecting frame 131 during movement, the cross rod 133 is blocked and stops moving downward, while the contact plate 129 continues to move and squeeze the rotating plate 137. The rotating plate 137 is squeezed and bends downward, and the surface of the contact plate 129 in contact with the deformed rotating plate 137 quickly separates, causing the deformed rotating plate 137 to quickly restore. The restoration of the deformed third spring 135 drives the cross rod 133 to reset upward. The movement of the cross rod 133 drives the sliding rod 134 to reset upward. The movement of the sliding rod 134 drives the portal frame 136 to reset upward. The movement of the portal frame 136 drives the rotating plate 137 to reset upward. By setting the elastic rotating plate 137, the rotating plate 137 can quickly separate from the contact plate 129 during deformation, thus ensuring that the rotating plate 137 can quickly reset to prepare for the next inspection.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
