Description

Technical Field

[0001] The invention relates to the technical field of inner hole detection of aluminum alloy components, in particular to a device for detecting the smoothness depth of inner holes on the surface of aluminum alloy precision components. Background Art

[0002] Aluminum alloy precision components refer to parts or structures with high precision, high quality and high performance made of aluminum alloy materials through fine processing. Aluminum alloy itself has the characteristics of low density, high strength and good corrosion resistance. On this basis, aluminum alloy precision components use advanced manufacturing processes such as precision casting and CNC machining to control dimensional tolerances and form and position tolerances within a very small range, and can achieve micron or even higher precision levels. Its shapes are complex and diverse, and its mechanical properties are excellent. It can achieve lightweight while ensuring strength and hardness. It is widely used in aircraft structural parts in the aerospace field, engine parts in the automotive industry, housings and internal components of electronic equipment, key components of medical devices, etc., and plays a vital role in many high-end industries; The Chinese patent with the announcement number "CN212674080U" discloses an inner hole diameter detection device for processing aluminum alloy bearing parts, which includes a base, a lighting mechanism and a detection placement plate. Universal wheels are arranged at the four corners of the lower end of the base, and a detection frame is fixed at the upper end of the base. Protective door bodies are arranged on both sides of the front end of the detection frame, and the protective door bodies are connected to the detection frame through hinges. The invention can ensure the firmness of the connection and the accuracy of the position between the detection placement plate and the rotating shaft that are vertically fixedly connected, and will not appear in the actual use. The position will not be offset, causing the detection placement plate to tilt and shake during the rotation process. The limiting slide groove provided on the lower part of the outer side of the detection placement plate cooperates with the limiting support blocks fixed on both sides of the lower inner side of the detection frame to ensure the stability of the detection placement plate during the rotation process, and will not tilt and shake. At the same time, the sliding structure ensures the smoothness of the rotation process; Although the above device can detect the reading inside the bearing hole, it obviously has certain defects and shortcomings during its specific application. First, it only uses a camera for detection. During the detection, it is necessary to rely on the naked eye to observe the situation captured by the camera to judge the situation inside the bearing hole. The camera obviously cannot specifically measure the smoothness of the inside of the hole or the depth of the hole. During its use, it is obviously unable to detect the diameter of the hole, the smoothness of the inner wall of the hole, and the diameter of the hole. In addition, during its application, it can only detect holes in the vertical direction. During its use, if the hole of the aluminum alloy precision component to be detected is located on the inclined surface, it is obviously unable to flexibly adjust. It can be seen that its adaptability to the detection of aluminum alloy precision components during the overall detection process is poor, and its overall detection performance of holes during the detection period is poor, so it needs to be improved; Although the above-mentioned device can detect the depth inside the bearing hole, there are obviously certain defects and shortcomings in specific applications. First of all, its detection method only relies on the camera. During the detection process, it is necessary to rely on the human eye to observe the situation captured by the camera to judge the condition inside the bearing hole. However, this camera is obviously unable to accurately measure the smoothness of the inside of the hole or the depth of the hole. Moreover, during use, it is obviously impossible to effectively detect the diameter of the hole, the smoothness of the inner wall of the hole, and the overall diameter of the hole. Moreover, during its application, it can only detect holes in the vertical direction. If the hole of the aluminum alloy precision component to be detected is located on the inclined surface, the device obviously cannot be flexibly adjusted. It can be seen that its adaptability to the detection of aluminum alloy precision components in the overall detection process is relatively weak, and during the detection period, the overall detection performance of holes is also relatively poor. For this reason, it is necessary to improve it. Summary of the invention

[0014] Compared with the prior art, the present invention has the following beneficial effects: First, in the present invention, the product to be tested is placed on the top of the electric cabinet, and the fifth motor is started to drive the second screw to rotate. Since the threads at both ends of the second screw have opposite rotation directions, the two displacement blocks can be driven to slide back and forth, and the auxiliary clamping plate displacement can realize flexible and rapid clamping of aluminum alloy precision metal components of different sizes, thereby improving adaptability. During the clamping and positioning, the telescopic cylinder can also be started to push the base plate to move up and down, and the height of the clamped component can be flexibly adjusted to adapt to the hole detection of components of different sizes; Secondly, in the present invention, by setting up a detection mechanism, after the aluminum alloy precision metal component is clamped and fixed, the telescopic cylinder is started to push the base plate up and down to adjust the height position of the component.

Fifth, in the present invention, a detection component is set. When in use, the third motor is started to drive the first screw rod to drive the sliding block to slide.

The up and down movement of the base plate 92 can adjust the height position of the aluminum alloy precision metal component, and in the overall adjustment process, the fourth motor 54 can be started to run. When the fourth motor 54 runs, it can drive the driving gear 55 to rotate. Since the driving gear 55 and the gear ring 53 are meshed and connected, the gear ring 53 can be driven to rotate by the driving gear 55. The rotation of the gear ring 53 can assist in driving the slip ring 51 to rotate. The rotation of the slip ring 51 can adjust the rotation of the detection component 64, so that the detection component 64 is displaced at the upper end of the aluminum alloy precision metal component to be detected. Such a design can flexibly change the detection direction of the detection component 64, so that the device has a stronger adaptability in the overall detection process, and can significantly improve the adaptability performance of the overall detection of the device. By setting up the detection mechanism 6, during the detection period of the device, as the driving mechanism 5 adjusts the gear ring 53 to rotate, the entire arc-shaped rail 61 can rotate, and the rotation of the arc-shaped rail 61 can flexibly adjust the rotation of the detection component 64. At this time, by starting the first electric push rod 654 to push the connecting frame 655 to move, the displacement of the connecting frame 655 can flexibly adjust the displacement of the driving gear 658 toward one side of the arc-shaped rack 653. When the driving gear 658 is meshed and connected with the driven gear 652 close to the arc-shaped rack 653, and then the first motor 657 is started to run, the first motor 657 drives the driving gear 658 to rotate, and the driving gear 6 58 and the driven gear 652 at the bottom are meshed for transmission. At this time, the driven gear 652 and the arc-shaped rack 653 can conflict with each other in the opposite direction, thereby causing the slide 62 to slide on the inner side of the arc-shaped rail 61. At this time, the slide 62 can slide inside the arc-shaped rail 61, and cooperate with the driving mechanism 5 to drive the arc-shaped rail 61 to rotate, so that the detection component 64 of the device can be flexibly adjusted to any position on the top of the clamped aluminum alloy precision metal component. It can be seen that the overall adaptability and adjustment ability of the device is relatively strong, and the overall device can be flexibly adjusted and adapted, and can adapt to the hole detection of aluminum alloy precision metal components in different directions, different angles and different positions; By setting the driving assembly 65, during the adjustment of the device, as the first electric push rod 654 pushes the driving gear 658 at the lower end close to the driven gear 652 on one side of the arc-shaped rack 653, the first motor 657 is started at this time to cooperate with the arc-shaped rack 653 to drive the slide 62 and the detection assembly 64 to slide and move, and when the first electric push rod 654 pushes the second motor 644 on the circular plate 656 close to the arc-shaped rack 653, the limiting tooth 6510 on the linkage rod 659 on the circular plate 656 can mesh with the driving gear 658 at the upper end. At this time, the driving gear 658 is locked and can fix the rotating shaft 641. After the adjustment is completed, the electric push rod can be started to retract, which can drive the driving gear 658 to move up. The driving gear 658 at the bottom can move up and mesh with the driving gear 658 at the top. At this time, the linkage rod 659 at the bottom drives the limit tooth 6510 to contact the driven gear 652 at the bottom, so as to lock and fix the driven gear 652 at the bottom. At this time, the driven gear 652 and the arc-shaped rack 653 are fixed to each other, so that the slide 62 can be fixed inside the arc-shaped rail 61. After the slide 62 is fixed, the first motor 657 can be started to drive the driving gear 658 to rotate. The driving gear 658 is meshed with the driven gear 652 at the top. At this time, the driving gear 658 and the driven gear 652 can be meshed with each other to drive the rotation shaft 641 to rotate flexibly. The rotation of the rotation shaft 641 can assist in driving the second electric push rod 642 to move for angle adjustment. The displacement of the second electric push rod 642 can flexibly adjust the direction of the detection component 645, so that the device can further adjust its tilt angle during the adjustment process. The overall detection adaptability of the device can be further improved. During this period, the driving gear 658 only needs to be pushed close to the two driven gears 652 by the first electric push rod 654. During this period, the limiting teeth 6510 at the end of the linkage rod 659 are engaged and fixed with the driven gears 652 that are far away. Therefore, the device only needs to use a single set of motors to flexibly drive the displacement of the detection component 64 and adjust its angle. It cooperates with the driving mechanism 5 and the clamping mechanism 9 to flexibly adapt to aluminum alloy precision components of different sizes, which significantly improves the overall use adaptability of the device. By setting up the detection component 64, during the use of the device, the third motor 6457 can be started to run, and the third motor 6457 can drive the first screw rod 6452 to drive the sliding block 6453 to slide back and forth inside the bottom rail 6451. Since the threads at both ends of the first screw rod 6452 are rotated in opposite directions, the sliding block 6453 can be flexibly adjusted to drive the reciprocating sliding. At this time, the sliding displacement of the sliding block 6453 can be adjusted to drive the two detection frames 6455 to move relative to each other. The mutual displacement of the detection frames 6455 can flexibly adjust the spacing between the rollers 6456. At this time, starting the second electric push rod 642 to run can drive the laser distance sensor 6459 and the second pressure sensor The detector 6458 is directed toward the hole of the aluminum alloy precision metal component. At this time, the detection frame 6455 can be inserted into the inside of the hole. At this time, the first screw rod 6452 can be used to drive the sliding block 6453 to slide back and forth, so that the sliding block 6453 drives the roller 6456 to fit inside the hole. At this time, the first pressure sensor 6454 detects the pressure. The detection frame 6455 is an elastic memory metal frame, which has a certain elasticity and can be reset. It can be set to a spring steel material. It can adaptively deform when rotating inside the hole, which can achieve a better detection effect. By calculating the encoder parameters of the third motor 6457, the number of turns of the screw rod can be obtained, and the sliding can be calculated at this time. The distance that the block 6453 is displaced can be used to calculate the diameter of the hole. As the second electric push rod 642 runs, the detection frame 6455 can be pushed to be inserted into the hole. When the second pressure sensor 6458 detects the bottom of the hole, the laser distance sensor 6459 can be started to run, and the depth of the hole can be detected. During this period, the second motor 644 can be started to run, and the second motor 644 can drive the detection frame 6455 to rotate. The roller 6456 on the outside of the detection frame 6455 fits the inside of the hole. As the second motor 644 drives the detection frame 6455 to rotate, the roller 6456 rolls inside the hole. If the inside of the hole is uneven, When there are defects, holes or lumps on the inner wall, it is obvious that the inside of the hole is uneven. At this time, when the roller 6456 rolls to the uneven place, it is resisted by the uneven inner wall of the hole, which can trigger the first pressure sensor 6454 at the roller 6456. Once the first pressure sensor 6454 has pressure information, it indicates that the inside of the hole is uneven and there are defects inside the hole. It can be seen that the device can quickly detect the diameter and depth of different holes and the smoothness of the internal holes during the overall application, which can significantly improve the adaptability of the device during the overall application. The overall detection does not require manual judgment, and the detection is relatively accurate, which can greatly improve the overall detection performance of the device.
