Description

Technical Field

[0001] This invention relates to the field of metal parts inspection and assembly technology, specifically to an automated inspection and assembly machine for balance tubes. Background Technology

[0002] In the automotive and hydraulic industries, balance tubes are core precision components used to balance pressure or fluid transmission in different chambers, and they typically have a strictly stepped shaft structure at both ends. To ensure the sealing and smooth flow of the balance tubes during subsequent assembly, they must undergo rigorous multi-process inspections before leaving the factory. These inspections include dimensional checks, coaxiality checks, and checks for microscopic defects on the tube surface (such as scratches, dents, and machining marks). After passing these inspections, the qualified parts are then assembled with sealing rings. However, traditional production models often employ a step-by-step operation, where dimensional, coaxiality, and surface defect checks are performed independently on different single machines. This reliance on manual labor for frequent transfers of the balance tubes between different workstations is highly significant.

[0003] In step-by-step balancing tube inspection, when the balancing tube is being inspected for coaxiality and surface defects, it must be driven to rotate at high speed around its own axis. To achieve this, existing equipment typically has a separate servo motor installed under each corresponding rotary inspection unit. Meanwhile, when inspecting for microscopic surface defects, because the balancing tube surface is cylindrical and in a state of high-speed dynamic rotation, existing technologies generally use a static, constantly lit light source in conjunction with an industrial camera to directly photograph the rotating balancing tube in order for the industrial camera to clearly capture the defects and extract depth information.

[0004] Currently, when performing coaxiality and surface defect detection on balanced tubes, it is essential to ensure that the tube rotates stably at a certain speed. This allows for continuous acquisition of radial runout via a coaxiality detection probe, and the entire surface of the tube can be clearly photographed using an industrial camera. However, to achieve rotational photography and dial indicator printing for balanced tubes, existing step-by-step single-machine equipment typically has servo motors independently installed under each corresponding rotational detection fixture. This step-by-step operation relies excessively on manual material transfer. Simply integrating these dispersed processes into a single multi-station machine would require an independent drive assembly at each rotational station. While this saves on manual transfer of the inspection parts, it results in a large space occupied by the drive assembly and a higher risk of internal transmission interference.

[0005] Therefore, the purpose of this invention is to provide an automated testing and assembly machine for balance tubes to address the shortcomings of existing technologies. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides an automated testing and assembly machine for balance tubes, which solves the problems of large equipment size, complex transmission structure, and internal interference caused by independently configuring motors at each rotary station.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an automated testing and assembly machine for a balance tube, comprising an operating table, wherein a multi-station adjustment component is provided on the operating table, the multi-station adjustment component being used to drive the rotating disk, connecting rod and support table to rotate, thereby enabling the balance tube to flow between different testing stations;

[0008] The rotating disk has a cavity inside, and a multi-station drive assembly is installed inside the cavity. The multi-station drive assembly is used to provide a common rotational power. The multi-station drive assembly includes a second gear, and a linkage assembly is installed on the second gear. The linkage assembly is used to drive the drive roller to rotate, thereby driving the balance tube that is in contact with the drive roller to rotate at high speed around its own axis to perform dynamic detection. The linkage component includes a third rotating shaft, which is fixedly connected to the outside of the second gear. The upper end of the third rotating shaft is fixedly connected to a multi-faceted mirror via a worm gear. The support platform is equipped with a moving component, a length detection component, and a defect detection component. The upper surface of the support platform is fixedly connected to a support plate via a second electric telescopic rod. The second electric telescopic rod is used to drive the support plate to rise and fall, so that the balance tube is lifted and physically separated from the drive roller to remain stationary during feeding and length detection, and lowered and in contact with the drive roller to maintain rotation during coaxiality and defect detection.

[0009] Preferably, a first drive motor is fixedly connected to the upper surface of the operating table, the output end of the first drive motor is fixedly connected to the rotating disk through a first rotating shaft, and the upper surface of the rotating disk is fixedly connected to the support platform through a connecting rod.

[0010] Preferably, the multi-station drive assembly includes a fixed plate fixedly connected to the inner surface of the cavity, a second drive motor fixedly connected to the lower surface of the fixed plate, a second rotating shaft fixedly connected to the output end of the second drive motor, a first gear fixedly connected to the side surface of the second rotating shaft, a second gear meshing with the side surface of the first gear, the second gear being fixedly connected to the third rotating shaft, and an internal gear ring meshing with the side surface of the second gear, the lower surface of the internal gear ring being rotatably connected to the rotating disk via a turntable, and the side surface of the third rotating shaft being fixedly connected to the support platform via a third bearing.

[0011] Preferably, a worm wheel is meshed with the side surface of the worm, and the inner surface of the worm wheel is fixedly connected to the drive roller via a fourth rotating shaft.

[0012] Preferably, a first support block and a second support block are fixedly connected to the upper surface of the support platform. The inner surface of the first support block is fixedly connected to a fourth rotating shaft through a first bearing. The inner surface of the second support block is fixedly connected to a rotating roller through a second bearing and a fifth rotating shaft.

[0013] Preferably, a first support block and a second support block are fixedly connected to the upper surface of the support platform. The inner surface of the first support block is fixedly connected to a fourth rotating shaft through a first bearing. The inner surface of the second support block is fixedly connected to a fifth rotating shaft through a second bearing. Rotating rollers are fixedly connected to the outer sides of both ends of the fifth rotating shaft.

[0014] Preferably, the moving component includes a first fixed rod, the first fixed rod having a first electric sliding groove inside, a first slider being slidably connected inside the first electric sliding groove, and a second fixed rod being fixedly connected to the upper surface of the first slider.

[0015] Preferably, the length detection component includes a first fixing frame, which is fixedly connected to the upper surface of the operating table, and a length detection sensor is disposed on the first fixing frame.

[0016] Preferably, the defect detection component includes a second mounting bracket, which is fixedly connected to the upper surface of the worktable, and a camera and an LED light are mounted on the second mounting bracket.

[0017] Preferably, a material unloading robot and a controller are fixedly connected to the upper surface of the operating table, a first material unloading frame is fixedly connected to the left surface of the operating table, and a second material unloading frame is fixedly connected to the rear surface of the operating table.

[0018] This invention provides an automated testing and assembly machine for balance tubes. It has the following advantages: 1. This invention integrates dimensional detection, coaxiality detection, and surface defect detection into a single machine by setting up an operating table, a multi-station adjustment component, a chamber, a multi-station drive component, a second electric telescopic rod, and a support plate. This solves the problem of production cycle delays caused by the high dependence on manual material transfer in step-by-step operations. At the same time, it overcomes the design limitation of multi-station equipment requiring independent motor configuration at each rotating station. Only one second drive motor is needed to simultaneously meet the power requirements of the coaxiality detection station and the surface defect detection station for the rotation of the balance tube. This simplifies the transmission structure at the bottom of the equipment, saves space, and avoids the internal transmission interference problems that are easily caused when multiple drive components coexist.

[0019] 2. While ensuring the smooth operation of the rotation detection process, this invention does not affect the static dimension detection of the balance tube. When the balance tube rotates to the loading station and the dimension detection station, the second electric telescopic rod drives the support plate to lift the balance tube to a certain height, so that the balance tube is physically separated from the multi-station drive component at the bottom. This allows the balance tube to remain stationary during length detection, providing a stable and reliable static measurement benchmark for the balance tube. This avoids wear on the tube surface caused by unexpected rotation and improves the accuracy of dimension detection.

[0020] 3. In this invention, while the multi-station drive assembly drives the balance tube to rotate at high speed for defect detection, the linkage assembly synchronously drives the multifaceted mirror to rotate rapidly. This causes the static, constantly lit light source to illuminate the rotating multifaceted mirror, and the light beam is instantly mechanically modulated into high-frequency flashing structural stripe light and dynamic scanning light. This overcomes the defects of local high-gloss reflection and motion blur that are easily generated when a static light beam directly illuminates a high-speed rotating cylindrical surface. At the same time, it can form a high-contrast light and dark scanning field on the tube surface, enabling the industrial camera to clearly capture the three-dimensional depth features of micro-morphology such as fine scratches and processing tool marks, thereby improving the accuracy and imaging effect of surface defect detection.

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see the appendix Figure 1 Appendix Figure 2 With appendix Figure 3 This invention provides an automated testing and assembly machine for balancing tubes, including an operating table 1. The operating table 1 is equipped with a multi-station adjustment component 2, which drives a rotating disk 203, a connecting rod 7, and a support platform 8 to rotate, thereby enabling the balancing tube to move between different testing stations. A first drive motor 201 is fixedly connected to the upper surface of the operating table 1. The output end of the first drive motor 201 is fixedly connected to the rotating disk 203 through a first rotating shaft 202. The upper surface of the rotating disk 203 is fixedly connected to the support platform 8 through the connecting rod 7.

[0025] Specifically, the first drive motor 201 is started, which drives the first rotating shaft 202 and the rotating disk 203 to rotate at a certain angle. The rotation of the rotating disk 203 drives the support platform 8 to rotate synchronously through the connecting rod 7, thereby automating the transfer of the balance tube test piece placed on the support platform 8 between different workstations. The placement, size detection, coaxiality detection and surface defect detection of the test piece are integrated into the same operating table 1, which solves the problem of production cycle delay caused by the high dependence on manual transfer of balance tubes to different workstations in the step-by-step operation of traditional single-machine equipment. It also effectively avoids secondary bumps and defects on the surface of the balance tube that are easily caused during the manual transfer of materials.

[0026] Using a motor to drive the rotating disk 203 to rotate at a fixed angle is a conventional technique in this field. There are four workstations evenly distributed along the circumference on the operating table 1. The first drive motor 201 drives the rotating disk 203 to rotate precisely by 90 degrees each time. Through the periodic stepping action of each 90-degree step, the balance tube detection component placed on the support table 8 can be accurately and synchronously switched between the loading workstation, the coaxiality detection workstation, the length detection workstation, and the surface defect detection workstation.

[0027] Please see the appendix Figure 4 With appendix Figure 5 The rotating disk 203 has a chamber 3 inside, and a multi-station drive assembly 5 is installed inside the chamber 3. The multi-station drive assembly 5 is used to provide common rotational power. The multi-station drive assembly 5 includes a fixed plate 4 fixedly connected to the inner surface of the chamber 3. A second drive motor 501 is fixedly connected to the lower surface of the fixed plate 4. A second rotating shaft 502 is fixedly connected to the output end of the second drive motor 501. A first gear 503 is fixedly connected to the side surface of the second rotating shaft 502. A second gear 504 is meshed with the side surface of the first gear 503. The second gear 504 is fixedly connected to a third rotating shaft 601, and an internal gear ring 505 is meshed with the side surface of the second gear 504. The lower surface of the internal gear ring 505 is rotatably connected to the rotating disk 203 through the turntable. The side surface of the third rotating shaft 601 is fixedly connected to the support platform 8 through a third bearing.

[0028] Specifically, the second drive motor 501 inside the start chamber 3 drives the second rotating shaft 502 and the first gear 503 to rotate. The rotation of the first gear 503 drives the second gear 504 and the internal gear ring 505 meshing with the second gear 504 to rotate. Because the internal gear ring 505 is rotatably connected to the rotating disk 203, the single rotational power generated by the second drive motor 501 can be smoothly distributed to each inspection station. Only one second drive motor 501 is needed to simultaneously meet the power requirements of the coaxiality inspection station and the surface defect inspection station for the high-speed rotation of the balance tube, simplifying the transmission structure at the bottom of the operating table 1, saving the space occupied by multiple sets of drive components, and avoiding the internal transmission interference problems that are easily caused when multiple sets of drive components coexist.

[0029] A lithium battery is installed inside the chamber 3 on one side of the second drive motor 501. The second drive motor 501 is electrically connected to the lithium battery. The second drive motor 501 rotates synchronously with the rotating disk 203. The use of built-in lithium battery power supply avoids the problem of external power supply cables getting tangled when the rotating disk 203 continues to rotate step by step.

[0030] The multi-station drive assembly 5 includes a second gear 504, on which a linkage assembly 6 is provided. The linkage assembly 6 is used to drive the drive roller 605 to rotate, thereby driving the balance tube that is in contact with the drive roller 605 to rotate at high speed around its own axis for dynamic detection. The side surface of the worm 602 is meshed with a worm wheel 603. The inner surface of the worm wheel 603 is fixedly connected to the drive roller 605 through a fourth rotating shaft 604. The upper surface of the support platform 8 is fixedly connected with a first support block 9 and a second support block 10. The inner surface of the first support block 9 is fixedly connected to the fourth rotating shaft 604 through a first bearing 11. The inner surface of the second support block 10 is fixedly connected to a fifth rotating shaft 13 through a second bearing 12. Rotating rollers 14 are fixedly connected to the outer sides of both ends of the fifth rotating shaft 13.

[0031] Specifically, when the second gear 504 rotates, it drives the third shaft 601 and the worm gear 602 on the third shaft 601 to rotate. The rotation of the worm gear 602 drives the meshing worm wheel 603 and the fourth shaft 604 passing through the inner surface of the worm wheel 603 to rotate. The rotation of the fourth shaft 604 drives the fixedly connected drive roller 605 to rotate within the first support block 9 and the first bearing 11. The rotation of the drive roller 605 causes friction to drive the balance tube detection component placed on the drive roller 605 and the rotating roller 14 to rotate at high speed around its own axis. A single second drive motor 501 can ensure that the balance tube detection component maintains a stable rotation speed, and can continuously acquire radial runout at the coaxiality detection station. At the defect detection station, in conjunction with the camera 1802, clear dynamic images of the entire surface of the balance tube detection component can be captured.

[0032] The worm 602 and worm wheel 603 are provided with a protective cover. The protective cover is used to prevent external impurities from falling into the transmission meshing area and causing jamming. The protective cover is not shown in this application. In order to highlight the structure of the worm 602 and worm wheel 603, the inner wall of the top of the protective cover is fixedly connected to the upper end of the worm 602 through a fourth bearing to make the rotation of the worm 602 stable.

[0033] Please see the appendix Figure 5 Appendix Figure 7 The linkage component 6 includes a third rotating shaft 601, which is fixedly connected to the outside of the second gear 504. The upper end of the third rotating shaft 601 is fixedly connected to a multifaceted mirror 15 via a worm gear 602.

[0034] Specifically, while the multi-station drive assembly 5 drives the balance tube to rotate at high speed for defect detection, the third rotating shaft 601 and the worm gear 602 synchronously drive the faceted mirror 15 to rotate rapidly. During each surface defect detection process, the static, constantly lit LED lamp 1803 emits a static beam of light, which illuminates the rotating faceted mirror 15. The faceted mirror 15 instantly modulates the static beam of light into high-frequency flashing structural stripe light and dynamic scanning light through pure mechanical modulation. The rotating faceted mirror 15 overcomes the defects of existing technologies where the static beam directly irradiates a high-speed rotating cylindrical surface, which easily produces localized high-gloss reflections and motion blur. Furthermore, it eliminates the need for a complex electrically controlled strobe assembly and can form a high-contrast light and dark scanning field on the surface of the balance tube detection component, thereby improving the accuracy and imaging effect of surface micro-defect detection.

[0035] Please see the appendix Figure 3 The upper surface of the support platform 8 is fixedly connected to the support plate 24 by the second electric telescopic rod 23. The second electric telescopic rod 23 is used to drive the support plate 24 to rise and fall, so that the balance tube is lifted and physically separated from the drive roller 605 to remain stationary when feeding and length detection is performed, and lowered and in contact with the drive roller 605 to maintain rotation when coaxiality and defect detection is performed.

[0036] Specifically, the second electric telescopic rod 23 and the support plate 24 are configured to ensure smooth operation of the rotation detection process without affecting the static dimensional detection of the balance tube. The second electric telescopic rod 23 and the support plate 24 are positioned between the fourth rotating shaft 604 and the fifth rotating shaft 13 to facilitate lifting the balance tube. When the first drive motor 201 drives the rotating disk 203 to rotate the balance tube to the loading and dimensional detection station, the second electric telescopic rod 23 is activated. The second electric telescopic rod 23 extends and drives the support plate 24 upward, lifting the balance tube to a specific height, thus physically separating the balance tube from the bottom drive roller 605 and rotating roller 14. After separating from the drive roller 605, the balance tube stops rotating, allowing it to remain stationary during length detection. This provides a stable and reliable static measurement benchmark for the balance tube, avoiding surface wear caused by rotation. Simultaneously, the fixed extension distance of the second electric telescopic rod 23 ensures a consistent dimensional detection height each time, thereby improving the accuracy of the dimensional detection. Each of the multiple second electric telescopic rods 23 is equipped with a lithium battery on one side. The lithium battery is electrically connected to the second electric telescopic rod 23, ensuring that the support platform 8 will not experience wire entanglement when rotating with the rotating disk 203.

[0037] Please see the appendix Figure 8 The support platform 8 is equipped with a moving component 16, a length detection component 17, and a defect detection component 18. The moving component 16 includes a first fixed rod 1601, a first electric slide groove 1602 is formed inside the first fixed rod 1601, a first slider 1603 is slidably connected inside the first electric slide groove 1602, a second fixed rod 1604 is fixedly connected to the upper surface of the first slider 1603, a second electric slide groove 1605 is formed inside the second fixed rod 1604, a second slider 1606 is slidably connected inside the second electric slide groove 1605, and a coaxiality detection probe 1608 is fixedly connected to the rear surface of the second slider 1606 through a first electric telescopic rod 1607.

[0038] Specifically, at the coaxiality detection station, the second electric telescopic rod 23 on one side of the moving component 16 is activated. The second electric telescopic rod 23 extends and moves back, causing the support plate 24 to descend, causing the balance tube detection component to be placed on the drive roller 605 and the rotating roller 14 and rotate synchronously at high speed with the drive roller 605. At this time, the first electric slide groove 1602 inside the first fixed rod 1601 is activated to drive the first slider 1603 to adjust its position back and forth, and the second electric slide groove 1605 inside the second fixed rod 1604 is activated to drive the second slider 1606 to adjust its position left and right, thereby precisely adjusting the three-dimensional spatial coordinates of the coaxiality detection probe 1608. After adjustment, the first electric telescopic rod 1607 is activated to push the coaxiality detection probe 1608 to move, causing the coaxiality detection probe 1608 to contact the surface of the rotating balance tube detection component. The coaxiality detection probe 1608 continuously acquires the radial runout of the balance tube detection component, thereby completing high-precision dynamic coaxiality detection. The second electric slide 1605 is activated to drive the coaxiality detection probe 1608 to move, which can complete the dynamic coaxiality detection of different positions of the balance tube.

[0039] Please see the appendix Figure 2 Appendix Figure 9 The length detection component 17 includes a first fixing frame 1701, which is fixedly connected to the upper surface of the operating table 1. A length detection sensor 1702 is provided on the first fixing frame 1701. The defect detection component 18 includes a second fixing frame 1801, which is fixedly connected to the upper surface of the operating table 1. A camera 1802 and an LED light 1803 are provided on the second fixing frame 1801.

[0040] Specifically, when the balance tube inspection component moves to the side of the length inspection assembly 17, it remains stationary due to the lifting and disengagement of the second electric telescopic rod 23 from the support plate 24. The length inspection sensor 1702 on the first fixed frame 1701 performs precise static dimension inspection on both ends of the stationary balance tube inspection component. The length inspection sensor 1702's length inspection of the stationary inspection component is existing technology. When the balance tube inspection component moves to the side of the defect inspection assembly 18, it rotates at high speed under the drive roller 605. Simultaneously, the statically arranged LED lights 1803 on the second fixed frame 1801 illuminate the static beam onto the synchronously high-speed rotating multifaceted mirror 15. The multifaceted mirror 15 mechanically modulates the static beam into a dynamic structured grating and projects it onto the surface of the balance tube inspection component. The camera 1802, in conjunction with the dynamic scanning light, clearly captures images of the entire surface of the balance tube inspection component. The camera 1802 clearly captures the micro-scratches, machining marks, and three-dimensional depth features on the surface of the balance tube inspection component.

[0041] Please see the appendix Figure 2 Appendix Figure 6The upper surface of the operating table 1 is fixedly connected to the unloading robot 19 and the controller 22, the left surface of the operating table 1 is fixedly connected to the first unloading frame 20, and the rear surface of the operating table 1 is fixedly connected to the second unloading frame 21.

[0042] Specifically, the controller 22 is equipped with a display screen and a PL control system. The controller 22 comprehensively receives various detection data from the coaxiality detection probe 1608, the length detection sensor 1702, and the camera 1802. After completing all multi-process inspections, the controller 22 issues action commands to the unloading robot 19 based on the judgment results. The unloading robot 19 picks up the inspected balance tube components. For balance tube components that pass the judgment, the loading robot precisely picks up the sealing ring from the sealing ring placement frame. The unloading robot 19, in cooperation with the loading robot, assembles the sealing ring onto the stepped shaft structures at both ends of the balance tube component. After the sealing ring assembly process is completed, the unloading robot 19 places the assembled qualified component in the first unloading frame 20. For defective components with dimensional deviations, coaxiality issues, or microscopic surface defects, the unloading robot 19 directly places the balance tube component into the second unloading frame 21 for isolation and scrapping. The entire process of automated flow, inspection, assembly, and sorting eliminates the need for manual judgment and transfer, thus improving the overall production and assembly efficiency of the balance tubes. The assembly of the sealing rings using two robotic arms is existing technology in this field.

[0043] Working principle: When using this device, start the second electric telescopic rod 23 on the feeding position side. The second electric telescopic rod 23 extends and moves to drive the support plate 24 to move. The feeding robot feeds the balance tube test piece and places it on the support plate 24 of the feeding position. Start the first drive motor 201 to drive the first rotating shaft 202 and the rotating disk 203 to rotate a certain angle, so that the balance tube test piece moves to the side of the moving component 16. Start the second electric telescopic rod 23 on the side of the moving component 16. The second electric telescopic rod 23 extends and moves back, so that the balance tube test piece is placed on the drive roller 605 and the rotating roller 14. Adjust the position of the coaxiality detection probe 1608 by starting the first electric slide 1602 and the second electric slide 1605. Start the first electric telescopic rod 1607 to make the coaxiality detection probe 1608 contact the balance tube test piece. The second drive motor 501 is started to drive the second rotating shaft 502 and the first gear 503 to rotate, which in turn drives the second gear 504 and the internal gear ring 505 to rotate. The rotation of the second gear 504 drives the third rotating shaft 601, the worm 602, the worm wheel 603, the fourth rotating shaft 604 and the drive roller 605 to rotate, which in turn causes the balance tube detection component to rotate. The coaxiality detection probe 1608 can perform coaxiality detection on the balance tube detection component. Under the action of the second electric slide 1605, the coaxiality detection probe 1608 can perform coaxiality detection on different positions of the balance tube detection component. At the same time, the feeding position feeds the next set of balance tube detection components under the action of the feeding robot. The first drive motor 201 is started to drive the first rotating shaft 202 and the rotating disk 203 to rotate at a certain angle, so that the balance tube test piece after coaxiality detection is moved to one side of the length detection component 17. The second electric telescopic rod 23 on one side of the length detection component 17 is started. The second electric telescopic rod 23 extends and moves to drive the support plate 24 to move, raising the balance tube test piece to the height of size detection. The length detection sensor 1702 detects the size of the balance tube test piece. At the same time, the loading position loads the next set of balance tube test pieces under the action of the loading robot. The coaxiality detection is repeated on one side of the moving component 16. The first drive motor 201 is started, which drives the first rotating shaft 202 and the rotating disk 203 to rotate at a certain angle, so that the dimensionally inspected balance tube inspection piece is moved to one side of the defect inspection component 18. The second electric telescopic rod 23 on one side of the defect inspection component 18 is started, and the second electric telescopic rod 23 extends and moves back, driving the support plate 24 to move, placing the balance tube inspection piece on the drive roller 605 and rotating roller 14 near the defect inspection component 18. The second drive motor 501 is started, and the drive roller 605 rotates, driving the balance tube inspection piece to rotate. At the same time, the worm gear 602 rotates, driving the multifaceted mirror 15 to rotate, changing the static LED light 1803 to form high-frequency flashing structural stripe light and dynamic scanning light. Under the action of the camera 1802, pictures are taken of different positions on the surface of the rotating balance tube inspection piece. The rotating multifaceted mirror 15 improves the accuracy and imaging effect of surface defect detection.
