Abstract
Description
Technical Field
[0001] This invention relates to the field of mechanical parts processing technology, and more specifically, to a high-precision intelligent detection device for mechanical parts processing. Background Technology
[0002] In the field of mechanical parts processing, especially in the production of precision mechanical parts, the key dimensional parameters such as concentricity and thickness, as well as the surface quality of the parts, directly determine the assembly accuracy, performance and service life of the product. Therefore, high-precision testing of mechanical parts is a core link in ensuring product quality.
[0003] Existing methods for inspecting concentric shafts involve using dial indicators or micrometers. This method only allows for the inspection of the outer diameter or a localized area of the inner cavity of the part, and cannot achieve comprehensive inspection of the inner cavity. It is prone to blind spots and cannot capture minute defects such as burrs in the inner cavity. It can only roughly determine the shaft center misalignment and cannot simultaneously ensure the accuracy of the shaft center and the surface quality of the inner cavity. As a result, defective parts flow into the next process, increasing rework and scrap costs. Summary of the Invention
[0004] The purpose of this invention is to provide a high-precision intelligent inspection device for machining mechanical parts, so as to solve the problems mentioned in the background art.
[0005] A high-precision intelligent inspection device for machining mechanical parts includes an operating table, an annular conveyor connected to the upper end of the operating table, detection components connected to both sides of one end of the annular conveyor, a marking component connected to the outer side of the detection components, a scanning device connected to the end of the annular conveyor away from the detection components, a pushing component installed at the end of the scanning device facing the marking component, and a control box connected to the front surface of the operating table, the control box carrying the inspection system. The detection component includes a moving component, both ends of which are connected to a detection mechanism, and a thickness detection component is connected to the upper surface of the concentric shaft detection component.
[0006] Preferably, a first chute is provided at the intersection of the operating table and the detection component, and a second chute is provided at the intersection of the operating table and the pushing component. A conveying trough is provided at the end of the operating table away from the detection component, and a receiving cavity is connected to the end of the conveying trough away from the annular conveying device. Several part placement blocks are connected to the upper surface of the annular conveying device, and placement grooves are provided on the upper surface of the part placement blocks. The spacing between each part placement block is equal. Each time, the annular conveying device rotates one station to perform a cyclic detection operation, pushing unqualified products into the receiving cavity, while qualified products are transported to the next processing stage by a robotic arm. Then, the robotic arm places the parts to be inspected into empty placement grooves.
[0007] Preferably, the moving component includes a first drive motor, the output end of which is connected to a rotating rod. Both ends of the rotating rod are connected to drive wheels. A rotating belt is sleeved on the outer side of each drive wheel. A secondary drive wheel is sleeved on the inner cavity of the end of each rotating belt away from the drive wheel. A first threaded rod is connected to the end of each secondary drive wheel facing the middle of the rotating rod. A first slider is connected to the outer side of each first threaded rod. The first threaded rods connected to the two ends of the rotating rod are opposite. A first infrared sensor is installed inside the detection component. When the first infrared sensor detects that the axis of the part in the placement groove is on the same straight line as the center of the detection component, the placement groove at the other end of the annular conveyor corresponds to the pushing component. Then, the rotation of the annular conveyor stops, and the first drive motor is started, thereby driving the rotating rod to rotate, which in turn drives the drive wheel to rotate. As the drive wheel rotates, it drives the rotating belt to rotate, which in turn drives the secondary drive wheel to rotate, which in turn drives the first threaded rod to rotate. As the first threaded rod rotates, it drives the first sliders installed at both ends of the rotating rod to move along the first groove toward the part.
[0008] Preferably, the concentric shaft detection assembly includes a first connecting block, the upper end of the first connecting block is connected to a second drive motor, the output end of the second drive motor is connected to a first gear, one end of the first gear meshes with an external gear ring, a rotating shaft is connected in the inner cavity of the external gear ring, a detection mechanism is connected to the end of the rotating shaft away from the external gear ring, and a third sliding groove is formed on the upper surface of the end of the first connecting block facing the middle part of the rotating rod, and scales are connected to the two ends of the third sliding groove.
[0009] Preferably, the detection mechanism includes a circular connecting block, the inner cavity of which has a plurality of holes. A first circular guide rod is connected to the inner cavity of each hole. A first return spring is sleeved on the outer side of each first circular guide rod, and a detection rod is connected to the end of each first circular guide rod away from the center of the circular connecting block. A detection block is connected to the outer side of the end of the detection rod facing the first return spring. A detection hole is formed at the intersection of the detection block and the detection rod. The end of the detection rod facing the inner cavity of the part is arc-shaped. The length of the circular connecting blocks connected to both ends of the rotating rod when they contact each other is... The sum of the degrees equals the length of the inner cavity of the part. When the tips of several detection rods contact the surface of the inner cavity of the part, if the detection rods coincide with the detection holes, it indicates that the concentricity of the part is qualified. If the first infrared sensor detects that a very small portion of the detection rods moves along the first circular guide rod toward the inner cavity of the hole, it indicates that there are burrs on the surface of the inner cavity of the part. If the first infrared sensor detects that a portion of the detection rods are not completely aligned with the detection holes, or if the detection rods move along the first circular guide rod toward the inner cavity of the hole, it indicates that the concentricity of the part is unqualified. In this case, the marking component will mark it.
[0010] Preferably, the thickness detection component includes a second slider, a semi-circular moving block connected to one end of the second slider facing the middle of the rotating rod, a second circular guide rod penetrating the upper surface of the second slider, a second return spring connected to the upper surface of the second circular guide rod, a pointer connected to the upper end of the second slider, and a semi-circular groove formed at one end of the semi-circular moving block facing the middle of the rotating rod. When the semi-circular grooves in the thickness detection components connected to both ends of the rotating rod come into contact, they form a circular hole that fits with the marking block. The edge of the semi-circular moving block facing the middle of the rotating rod is arc-shaped.
[0011] Preferably, the marking assembly includes a lifting rod, a marking device connected to the middle outer surface of the lifting rod, and second threaded rods sleeved on both ends of the lifting rod. A third drive motor is connected to the lower end of each second threaded rod, and a rectangular guide frame is connected to the outer side of each second threaded rod. When the first infrared sensor detects that the concentric shaft or thickness of the part is unqualified, the detection system will start the third drive motor and drive the second threaded rod to rotate, thereby causing the lifting rod to move downward along the second threaded rod until the lower end of the marking device coincides with the circular hole formed by the contact of the two semi-circular grooves. At this time, the marking device marks the part and then returns to its original position.
[0012] Preferably, the pushing assembly includes a fourth drive motor, the output end of the fourth drive motor is connected to a third threaded rod, a third slider is sleeved on the outside of the third threaded rod, and a circular pushing rod is connected to the end of the third slider facing the conveying groove, the circular pushing rod fitting into the placement groove.
[0013] Preferably, the first slider is engaged with the first groove, the second slider is engaged with the third groove, and the third slider is engaged with the second groove.
[0014] Compared with the prior art, the advantages of this invention are: 1. In this invention, by employing a multi-rod surround detection mechanism in conjunction with a rotating detection structure driven by a second drive motor, the detection mechanism can rotate at a constant speed around the inner cavity of the part, enabling a blind-angle detection operation of the part's inner cavity. Furthermore, the combined design of the detection rod, the first circular guide rod, and the first reset spring in the detection mechanism allows the detection rod to adaptively conform to the surface of the part's inner cavity. Combined with the precise fit between the detection block and the detection hole, it can not only accurately determine the degree of concentric axis offset but also keenly detect minute defects such as extremely small-sized burrs in the inner cavity. At the same time, the sum of the lengths of the circular connecting blocks at both ends of the rotating rod when they contact each other is precisely matched with the length of the part's inner cavity, ensuring full contact between the detection rod and the inner cavity surface, further improving the accuracy and reliability of the concentric axis detection.
[0015] 2. In this invention, the concentric shaft detection component and the thickness detection component are integrated into the detection component. The two key parameters of concentric shaft accuracy and part thickness are detected simultaneously in a single detection process. This eliminates the need for multiple part transfers or step-by-step detection, avoiding secondary damage to parts and significantly shortening the detection cycle. It is suitable for the continuous detection needs of large batches of parts. Furthermore, the thickness detection, through the precise coordination of the pointer and scale, combined with the buffering effect of the second return spring, can accurately read the part thickness value. This works in synergy with the concentric shaft detection to control the part processing quality and avoid data distortion caused by clamping misalignment or inconsistent detection benchmarks, thereby further improving detection accuracy.
[0016] 3. In this invention, the concentric shaft detection mechanism achieves precise linkage with the first infrared sensor, the detection system, and the marking component. The first infrared sensor collects the position status of the detection rod in real time and automatically determines whether the concentric shaft is qualified or not. When the concentric shaft is detected as unqualified, the detection system immediately triggers the marking component to complete precise marking. The subsequent linkage scanning device and the pushing component realize the automatic sorting of unqualified parts, forming an automated closed loop of concentric shaft detection, judgment, marking, and sorting. This greatly reduces manual input, reduces the labor intensity of operators, and at the same time reduces the flow of unqualified parts into the next process, reducing rework costs and scrap rate.

[0021] Please see Figure 3 The moving component 301 includes a first drive motor 304, the output end of which is connected to a rotating rod 305. Both ends of the rotating rod 305 are connected to a drive wheel 306. A rotating belt 307 is sleeved on the outer side of each drive wheel 306. A secondary drive wheel 308 is sleeved on the inner cavity of the end of each rotating belt 307 away from the drive wheel 306. A first threaded rod 309 is connected to the end of each secondary drive wheel 308 facing the middle of the rotating rod 305. A first slider 310 is connected to the outer side of each first threaded rod 309. The first threaded rods 309 connected to the two ends of the rotating rod 305 are opposite. A first infrared sensor is installed inside the detection component 3. Several connecting grooves are opened on the inner surface of the rotating belt 307. Several third connecting blocks are connected to the outer surfaces of the drive wheel 306 and the secondary drive wheel 308. The third connecting blocks mesh with the connecting grooves.
[0022] Please see Figure 4 The concentric shaft detection assembly 302 includes a first connecting block 311. The upper end of the first connecting block 311 is connected to a second drive motor 312. The output end of the second drive motor 312 is connected to a first gear 313. One end of the first gear 313 meshes with an external gear ring 314. A rotating shaft 315 is connected in the inner cavity of the external gear ring 314. The end of the rotating shaft 315 away from the external gear ring 314 is connected to a detection mechanism 316. A third sliding groove 323 is opened on the upper surface of the end of the first connecting block 311 facing the middle part of the rotating rod 305. A scale 324 is connected to both ends of the third sliding groove 323.
[0023] Please see Figure 5 and Figure 6The detection mechanism 316 includes a circular connecting block 317. The inner cavity of the circular connecting block 317 has several holes 318. A first circular guide rod 319 is connected to the inner cavity of each hole 318. A first return spring 331 is sleeved on the outer side of each first circular guide rod 319. A detection rod 320 is connected to the end of each first circular guide rod 319 away from the center of the circular connecting block 317. A detection block 321 is connected to the outer side of the end of the detection rod 320 facing the first return spring 331. A detection hole 322 is provided at the intersection of the detection block 321 and the detection rod 320. The end of the detection rod 320 facing the inner cavity of the part is arc-shaped. The total length of the circular connecting blocks 317 connected to both ends of the rotating rod 305 when they are in contact is equal to the length of the inner cavity of the part. The first connecting block 311 is fixedly connected to the first slider 310, and the circular connecting block 317 is rotatably connected to the first connecting block 311.
[0024] Specifically, by integrating the concentric shaft detection component 302 and the thickness detection component 303 into the detection component 3, the two key parameters of concentric shaft accuracy and part thickness are detected simultaneously in a single detection process. This eliminates the need for multiple part transfers or step-by-step detection, avoiding secondary damage to parts and significantly shortening the detection cycle. It is suitable for the continuous detection needs of large batches of parts. Furthermore, the thickness detection, through the precise cooperation of the pointer 329 and the scale 324, combined with the buffering effect of the second return spring 328, can accurately read the part thickness value. This works in synergy with the concentric shaft detection to control the part processing quality, thereby avoiding data distortion caused by clamping offset and inconsistent detection benchmarks, and further improving detection accuracy.
[0025] Please see Figure 7 The thickness detection component 303 includes a second slider 325. A semi-circular moving block 326 is connected to one end of the second slider 325 facing the middle part of the rotating rod 305. A second circular guide rod 327 passes through the upper surface of the second slider 325. A second return spring 328 is connected to the upper surface of the second circular guide rod 327. A pointer 329 is connected to the upper end of the second slider 325. A semi-circular groove 330 is opened at one end of the semi-circular moving block 326 facing the middle part of the rotating rod 305. When the semi-circular grooves 330 in the thickness detection component 303 connected to both ends of the rotating rod 305 come into contact, a circular hole is formed and fits with the marking block. The edge of the semi-circular moving block 326 facing the middle part of the rotating rod 305 is arc-shaped.
[0026] Specifically, by employing a multi-rod surround detection mechanism 320, in conjunction with a rotating detection mechanism 316 driven by a second drive motor 312, the detection mechanism 316 can rotate uniformly around the inner cavity of the part, enabling a seamless detection operation of the part's inner cavity. Furthermore, the combined design of the detection rods 320, the first circular guide rod 319, and the first return spring 331 within the detection mechanism 316 allows the detection rods 320 to adaptively conform to the surface of the part's inner cavity. Combined with the precise fit between the detection block 321 and the detection hole 322, it can not only accurately determine the degree of concentric shaft offset but also keenly detect minute defects such as extremely small burrs in the inner cavity. Simultaneously, the total length of the circular connecting blocks 317 at both ends of the rotating rod 305 when they contact each other precisely matches the length of the part's inner cavity, ensuring full contact between the detection rods 320 and the inner cavity surface, further improving the accuracy and reliability of the concentric shaft detection.
[0027] Please see Figure 8 The marking component 4 includes a lifting rod 401, a marking device 402 connected to the middle outer surface of the lifting rod 401, and second threaded rods 403 sleeved on both ends of the lifting rod 401. The lower end of each second threaded rod 403 is connected to a third drive motor 404, and a rectangular guide frame is connected to the outer side of each second threaded rod 403. When the first infrared sensor detects that the concentric shaft or thickness of the part is unqualified, the detection system will start the third drive motor 404 and drive the second threaded rods 403 to rotate, thereby causing the lifting rod 401 to move downward along the second threaded rods 403 until the lower end of the marking device 402 coincides with the circular hole formed by the contact of the two semi-circular grooves 330. At this time, the marking device 402 marks the part and then returns to its original position.
[0028] Please see Figure 9 The feeding assembly 6 includes a fourth drive motor 601, the output end of the fourth drive motor 601 is connected to a third threaded rod 602, a third slider 603 is sleeved on the outside of the third threaded rod 602, and a circular push rod 604 is connected to one end of the third slider 603 facing the conveying groove 9. The circular push rod 604 fits into the placement groove.
[0029] Specifically, the concentric shaft detection mechanism achieves precise linkage with the first infrared sensor, the detection system, and the marking component 4. The first infrared sensor collects the position status of the detection rod in real time and automatically determines whether the concentric shaft is qualified or not. When a concentric shaft is detected as unqualified, the detection system immediately triggers the marking component 4 to complete precise marking. Subsequently, the linkage scanning device 5 and the pushing component 6 realize the automatic sorting of unqualified parts, forming an automated closed loop of concentric shaft detection, judgment, marking, and sorting. This greatly reduces manual input, reduces the labor intensity of operators, and at the same time reduces the flow of unqualified parts into the next process, reducing rework costs and scrap rate.
[0030] The first slider 310 is engaged with the first groove 7, the second slider 325 is engaged with the third groove 323, and the third slider 603 is engaged with the second groove 8.
[0031] Working principle: The robotic arm accurately places the mechanical parts to be inspected into the placement groove of the part placement block 11 at the upper end of the circular conveyor 2. Several part placement blocks 11 are evenly distributed at intervals. The circular conveyor 2 rotates one station at a time according to the preset program to continuously convey and inspect the parts. At this time, the circular conveyor 2 drives the part placement block 11 carrying the parts to move towards the inspection component 3. The first infrared sensor installed inside the inspection component 3 detects the position of the parts in real time. When it is detected that the axis of the part in the placement groove is in the same straight line as the center of the inspection component 3, the inspection system immediately controls the circular conveyor 2 to stop rotating. At this time, the empty placement groove at the other end of the circular conveyor 2 corresponds exactly to the pusher component 6, which not only ensures the accuracy of the part inspection benchmark, but also prepares for the subsequent sorting of unqualified parts and the loading of new parts. After the part is positioned, the detection system starts the first drive motor 304 in the detection component 3, drives the rotating rod 305 to rotate, and then drives the drive wheels 306 at both ends of the rotating rod 305 to rotate synchronously. The drive wheels 306 drive the secondary drive wheels 308 to rotate through the rotating belt 307, thereby driving the two first threaded rods 309 to rotate synchronously, and then driving the first slider 310 sleeved on the outside of the first threaded rod 309 to move synchronously along the first slide groove 7 toward the part, and driving the concentric shaft detection component 302 and the thickness detection component 303 to move toward the part until the first slider 310 moves to the other end of the first slide groove 7; During the movement, when the semi-circular moving block 326 in the thickness detection component 303 contacts the surface of the part, the part exerts a counterforce on the semi-circular moving block 326, thereby pushing the second slider 325 upward along the second circular guide rod 327, and thus compressing the second return spring 328; when the first slider 310 stops moving at the other end of the first slide groove 7, the pointer 329 at the upper end of the second slider 325 points exactly to the scale 324 at both ends of the third slide groove 323, and the value pointed to by the pointer 329 is the actual thickness of the part. At this time, the first infrared sensor transmits the thickness value to the detection system and compares it with the preset thickness threshold: if the value is within the threshold range If the thickness of the part is deemed acceptable, the next step of concentric shaft inspection is initiated. If the value exceeds the threshold, the thickness is deemed unacceptable. The inspection system immediately triggers the marking component 4 to prepare for marking. At this time, the third drive motor 404 starts, driving the second threaded rod 403 to rotate. The lifting rod 401 moves downward along the second threaded rod 403. When the lower end of the marking device 402 on the lifting rod 401 coincides with the circular hole formed by the splicing of the two semi-circular grooves 330, the marking device 402 accurately marks the part. After marking is completed, the third drive motor 404 rotates in the opposite direction, driving the lifting rod 401 and the marking device 402 back to the initial position, waiting for the next marking instruction. When the first slider 310 moves to the other end of the first slide groove 7, the circular connecting blocks 317 in the concentric shaft detection assembly 302 at both ends of the rotating rod 305 come into contact with each other. At this time, the detection system starts the second drive motor 312, drives the first gear 313 to rotate, thereby driving the outer gear ring 314 and the rotating shaft 315 connected to its inner cavity to rotate, and then driving the detection mechanism 316 to rotate synchronously, realizing the all-round concentric shaft detection of the inner cavity of the part. During the process of the detection mechanism 316 performing concentric shaft rotation detection, the first infrared sensor detects the position status of the detection rod 320 in real time. If all the detection rods 320 are completely aligned with the detection holes 322, it indicates that the inner surface of the part is flat and the axis is accurate, and the concentric shaft test is qualified. If the first infrared sensor detects that a very small part of the detection rods 320 move along the first circular guide rod 319 into the inner cavity of the hole 318, it indicates that there are burrs on the inner surface of the part, and the concentric shaft test is unqualified. If it is detected that a part of the detection rods 320 are not completely aligned with the detection holes 322, or that the detection rods 320 move into the inner cavity of the hole 318, it indicates that the axis of the part is offset and the concentricity does not meet the standard, and the concentric shaft test is unqualified. If it is detected that all the detection rods 320 move into the inner cavity of the hole 318, it indicates that the inner diameter of the part does not meet the standard, and the concentric shaft test is unqualified. All of the above unqualified situations will trigger the detection system and start the marking component 4 to mark. After marking is completed, the detection system controls the first drive motor 304 to rotate in the opposite direction, driving the rotating rod 305, the driving wheel 306, the rotating belt 307, the secondary driving wheel 308 and the first threaded rod 309 to move in the opposite direction, so that the first slider 310, the concentric shaft detection component 302 and the thickness detection component 303 are all restored to their initial positions, completing a single detection process. Subsequently, the ring conveyor 2 rotates one station again to transport the detected part to the scanning device 5, and at the same time transports the next part to be detected to the detection station. The scanning device 5 scans the delivered parts. If a part is marked, when the part moves to the pusher station, the detection system activates the fourth drive motor 601 of the pusher assembly 6, driving the third threaded rod 602 to rotate. This drives the third slider 603 to move along the second chute 8 towards the conveyor chute 9. The third slider 603 drives the circular pusher rod 604 to move synchronously. Since the circular pusher rod 604 fits into the placement groove, when the third slider 603 moves to the other end of the second chute 8, the circular pusher rod 604 pushes the defective parts out of the placement groove. The parts slide down the conveyor chute 9 into the receiving cavity 10, completing the sorting of defective parts. If a part is unmarked, the ring conveyor 2 continues to rotate, and the robotic arm transports the qualified parts to the next processing stage. After the qualified parts are taken away, the robotic arm immediately places the new parts to be inspected into the empty placement groove. The ring conveyor 2 continues to rotate one station, entering the next round of inspection cycle, thus ending all operations.
