Description

Technical Field

[0001] This application relates to the field of mechanical testing, and in particular to a planetary carrier torque testing device. Background Technology

[0002] In the field of mechanical testing, planetary carriers, as key components of mechanical transmission systems, significantly impact the operational stability and reliability of the entire mechanical system. The torque performance of the planetary carrier is one of the key indicators for measuring its quality. Accurate torque testing of planetary carriers is of paramount importance for ensuring product quality, improving production efficiency, and reducing costs. Precise torque testing can promptly identify problems in planetary carrier production, preventing substandard products from entering the market and improving the reliability and safety of the mechanical system. Simultaneously, efficient testing methods can meet the needs of large-scale production. In high-end manufacturing industries such as aerospace, automotive manufacturing, and precision instruments, the torque accuracy requirements for planetary carriers are extremely high; even minute torque deviations can lead to equipment failure. Therefore, accurate and efficient planetary carrier torque testing technology is a key requirement for industry development. In existing related technologies, planetary carrier torque testing devices typically employ manual testing. The testing principle involves the inspector manually placing the planetary carrier in the positioning slot of the testing tool and clamping it. Then, a certain torque is applied to the planetary carrier using a torque wrench or other tools that can automatically display the torque. During operation, the inspector relies on their experience and intuition to control the magnitude and direction of the applied torque. Then, inspectors determine whether the planetary carrier's torque meets the requirements based on whether the displayed torque reaches the threshold. Finally, good and defective planetary carriers are sorted manually. In some small factories or situations where the precision requirements for planetary carriers are not high, this manual inspection method is still widely used. However, with the continuous expansion of production scale and the increasing demands for product quality, the limitations of this inspection method have gradually become apparent.

[0003] However, existing planetary carrier torque testing devices still have significant shortcomings in practical applications. These shortcomings primarily manifest in their inability to meet the demands of large-scale, efficient, and precise testing. The entire process requires manual intervention in the loading, testing, and screening of the planetary carriers, leading to low testing efficiency. Furthermore, inconsistencies in the force and angle applied during manual operation can easily cause deviations in the test results. Therefore, existing planetary carrier torque testing devices cannot meet the modern industrial requirements for efficient and accurate planetary carrier torque testing. Summary of the Invention

[0004] To meet the demands of large-scale, efficient, and high-precision processing, and to achieve automated feeding, inspection, and screening of planetary carriers while improving inspection smoothness and processing efficiency, this application provides a planetary carrier torque detection device.

[0005] This application provides a planetary carrier torque testing device, including a frame, a feeding mechanism, a clamping mechanism, a torque testing mechanism, a screening and unloading mechanism, and a control system for regulating the operation of each mechanism, all mounted on the frame. The feeding mechanism is used to transport the planetary carrier to the picking station. The clamping mechanism includes a first mechanical claw and a second mechanical claw that can move synchronously. The first mechanical claw grabs the planetary carrier at the picking station and transfers it to the testing station of the torque testing device for torque testing. Simultaneously, the second mechanical claw clamps the planetary carrier that has been tested at the testing station and transfers it to the unloading station of the screening and unloading mechanism. The screening and unloading mechanism includes a qualified product guide structure and a non-qualified product guide structure. The control system controls the qualified product guide structure or the non-qualified product guide structure to move to the unloading station to receive the planetary carrier based on the test result of the torque testing device. By adopting the above technical solution, the feeding mechanism can transport the planetary carrier to the unloading station, realizing automatic feeding of the planetary carrier. The first and second mechanical claws of the clamping mechanism can move synchronously. The first mechanical claw grabs the planetary carrier at the unloading station and transfers it to the testing station for torque testing. The second mechanical claw simultaneously clamps the tested planetary carrier and transfers it to the unloading station. This synchronous operation allows the feeding and unloading processes to run in parallel, greatly saving time and improving testing efficiency. Furthermore, it avoids deviations in testing results caused by inconsistent operating force and angle during manual operation, ensuring the accuracy of the testing. The screening and unloading mechanism is equipped with a qualified product guide structure and a non-qualified product guide structure. The control system controls the corresponding guide structure to move to the unloading station to receive the planetary carrier based on the torque test results, realizing automatic screening and unloading of the planetary carrier without manual screening, further improving testing efficiency. It also reduces the interference of human factors on the screening results, ensuring the accuracy of the screening results, thus meeting the needs of large-scale, high-efficiency precision testing. Preferably, the torque detection device includes a test bench, a drive assembly, a transmission assembly, a measurement and analysis assembly, and a clamping assembly. The drive assembly applies torque, the transmission assembly transmits torque, the measurement and analysis assembly collects and processes torque and angle data in real time, and the clamping assembly is used to fix the planetary carrier to the testing position on the test bench. By adopting the above technical solution, the drive assembly can apply torque, and the transmission assembly can transmit the torque applied by the drive assembly to the planetary carrier, causing the planetary carrier to be subjected to torque. The measurement and analysis assembly can collect and process the torque and angle data of the planetary carrier under torque in real time, thereby obtaining information related to the torque performance of the planetary carrier. The clamping assembly can fix the planetary carrier to the testing position on the test bench, preventing the planetary carrier from moving or shaking during the testing process, ensuring the stability and accuracy of the testing process. Combining the functions of these components, automatic and accurate detection of the planetary carrier torque is achieved, solving the problems of low efficiency and easy deviation in results of manual testing in the prior art, meeting the needs of large-scale, high-efficiency precision testing, and improving testing efficiency and the accuracy of test results.Preferably, the transmission assembly includes a rotating shaft, and the clamping assembly includes a mounting plate, a mounting cylinder, a sleeve fitted onto the rotating shaft, and a clamping cylinder disposed at the end of the sleeve. The mounting cylinder passes through the mounting plate and its bottom is located directly above the test bench. The sleeve passes through the mounting cylinder, and its bottom is provided with the clamping cylinder for clamping the edge of the planetary carrier. The rotating shaft can rotate within the sleeve and transmit torque to the planetary carrier. By adopting the above technical solution, the mounting cylinder passes through the mounting plate and its bottom is located directly above the test bench, allowing the sleeve to be positioned appropriately within the mounting cylinder to operate the planetary carrier on the test bench. The clamping cylinder at the bottom of the sleeve can clamp the edge of the planetary carrier, ensuring the stability of the planetary carrier during the testing process and preventing displacement or shaking when subjected to torque. The rotating shaft can rotate within the sleeve; this structural design allows the rotating shaft to accurately transmit the torque applied by the drive assembly to the planetary carrier, thereby achieving torque detection of the planetary carrier. This structure, through its rational layout and component coordination, can more accurately apply torque to the planetary carrier, reducing deviations in test results and improving the accuracy and reliability of testing. This better meets the needs of large-scale, high-efficiency precision testing, improving the quality and efficiency of planetary carrier torque testing. Preferably, the first and second mechanical claws are connected by a connecting plate, and the bottom of the connecting plate is provided with a linear drive structure. This linear drive structure drives the connecting plate to move between the material handling station and the unloading station. By adopting the above technical solution, the first and second mechanical claws are connected by a connecting plate, and the bottom of the connecting plate is provided with a linear drive structure, which drives the connecting plate to move between the material handling station and the unloading station. This connection and drive method allows the first and second mechanical claws to move synchronously and stably. During the planetary carrier testing process, the first mechanical claw can accurately grasp the planetary carrier at the material handling station and transfer it to the testing station, while the second mechanical claw can promptly clamp the tested planetary carrier and transfer it to the unloading station, achieving efficient connection between planetary carrier loading and unloading. This improves the efficiency of planetary carrier torque detection and ensures the positional accuracy of the planetary carrier during the detection process, thereby improving the accuracy of the detection results and meeting the needs of large-scale, high-efficiency precision testing. Preferably, both the first and second mechanical grippers are equipped with two gripping rods and a gripping rod drive unit that drives the two gripping rods to open and close. The gripping rods are provided with arc-shaped grooves that match the contour of the planetary carrier. By adopting the above technical solution, the first and second mechanical grippers are equipped with two gripping rods and a gripping rod drive unit that drives their opening and closing, and the gripping rods are provided with arc-shaped grooves that match the contour of the planetary carrier. During the gripping and transfer operation of the planetary carrier, the gripping rod drive unit drives the two gripping rods to open and close. When the two gripping rods are closed, the arc-shaped grooves that match the contour of the planetary carrier can tightly fit the planetary carrier, increasing the contact area with the planetary carrier and thus providing a more stable gripping force.This prevents the planetary carrier from shaking or falling during transport, reducing detection errors caused by carrier movement. Preferably, the first and second robotic claws are spaced apart and horizontally positioned along the direction from the material handling station to the detection station, and the distance between them matches the distance between the material handling station and the detection station. By adopting the above technical solution, the first and second robotic claws are spaced apart and horizontally positioned along the direction from the material handling station to the detection station, and the distance between them matches the distance between the material handling station and the detection station. This arrangement ensures that when the first robotic claw picks up the planetary carrier from the material handling station and transports it to the detection station, the second robotic claw is precisely at the detection station and can directly clamp the inspected planetary carrier, achieving synchronous and efficient operation of the two robotic claws. This avoids unnecessary movement and waiting time for the robotic claws during material handling and unloading, reduces the overall operating time of the equipment, improves the loading and unloading efficiency of the planetary carrier, and thus improves the detection efficiency of the entire planetary carrier torque detection device. Preferably, the feeding mechanism includes a vibrating plate and a linear vibrating track. The feeding end of the linear vibrating track is connected to the discharging end of the vibrating plate, and the discharging end of the linear vibrating track is provided with the picking station. By adopting the above technical solution, the feeding mechanism is equipped with a vibrating plate and a linear vibrating track. The vibrating plate causes the planetary carrier to vibrate continuously, promoting the orderly arrangement of the planetary carriers and their movement towards the linear vibrating track. The feeding end of the linear vibrating track is connected to the discharging end of the vibrating plate, receiving the planetary carriers output from the vibrating plate and continuously conveying them to the picking station at the discharging end using vibration. This improves the efficiency and accuracy of feeding, meeting the needs of large-scale, high-efficiency precision testing. Preferably, the picking station is provided with a limiting block to prevent the planetary carrier from moving. By adopting the above technical solution, the limiting block at the picking station can block the planetary carrier when it is conveyed to the picking station by the feeding mechanism, preventing it from continuing to move and ensuring that the planetary carrier remains stably at the picking station. Preferably, the screening and feeding mechanism further includes a movable base and a sliding drive structure. The qualified product guide structure and the unqualified product guide structure are respectively disposed on both sides of the sorting base, and the sliding drive structure drives the base to move. By adopting the above technical solution, the screening and feeding mechanism is provided with a movable base and a sliding drive structure, with the qualified product guide structure and the unqualified product guide structure located on both sides of the base. When the control system controls the sliding drive structure to drive the base to move according to the detection result of the torque detection device, the corresponding qualified product guide structure or unqualified product guide structure can be moved to the feeding station to receive the planetary carrier. This design improves detection efficiency and avoids screening errors caused by inconsistent operating force and angle during manual operation, improving the accuracy and reliability of screening, and better meeting the needs of large-scale, high-efficiency precision testing. Preferably, the measurement and analysis component further includes a torque sensor, which is used to monitor the torque value applied by the rotating shaft in real time.By adopting the above technical solution, a torque sensor is set in the measurement and analysis component. The torque sensor can cooperate with the rotating shaft. Since the rotating shaft is responsible for transmitting torque to the planetary carrier, the torque sensor can monitor the torque value applied by the rotating shaft in real time.

[0006] In summary, this application includes at least one of the following beneficial technical effects: 1. The vibrating plate and linear vibrating track in the feeding mechanism can transport the planetary carrier to the picking station. The first mechanical claw of the clamping mechanism grabs the planetary carrier at the picking station and transfers it to the inspection station. At the same time, the second mechanical claw synchronously transfers the inspected planetary carrier to the unloading station. With the help of the torque detection mechanism and the screening and unloading mechanism, the automatic feeding, inspection and screening of planetary carriers can be realized without the need for full manual intervention, avoiding the tedious process of manual feeding, inspection and screening, thereby improving the inspection efficiency. 2. The drive component of the torque detection device can apply torque, the transmission component can transmit the torque applied by the drive component to the planetary carrier, the measurement and analysis component can collect and process the torque and angle data of the planetary carrier under torque in real time, and the clamping component can fix the planetary carrier to the testing station of the test bench. By combining the functions of these components, the automatic and accurate detection of the torque of the planetary carrier is realized.

[0007] 3. The control system can control the sliding drive structure of the screening and feeding mechanism to move the base according to the detection results of the torque detection mechanism, so that the qualified product guide structure or the unqualified product guide structure moves to the feeding station to receive the planetary carrier, thus realizing the automatic screening of the planetary carrier.

[0010] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0011] This application provides a planetary carrier torque detection device, referring to... Figure 1 and Figure 2 The system includes a frame 1, a feeding mechanism 2, a clamping mechanism 3, a torque detection mechanism 4, a screening and unloading mechanism 5, and a control system. The feeding mechanism 2, clamping mechanism 3, torque detection mechanism 4, and screening and unloading mechanism 5 are all mounted and fixed on the frame 1. The control system is connected to the power components of each mechanism via wires to regulate the operation of each mechanism, realizing the automated process of the planetary carrier 6 from feeding to detection to screening and unloading, thus improving detection efficiency and accuracy.

[0012] Specifically, in this embodiment, the feeding mechanism 2 consists of a vibratory feeder 21 and a linear vibratory track 22. The vibratory feeder 21 continuously vibrates, causing the planetary carrier 6 to rise and enter the linear vibratory track 22. The linear vibratory track 22 then transports the planetary carrier 6 to the unloading station 23. Together, they achieve the orderly transport of the planetary carrier 6. Specifically, the vibratory feeder 21 adopts a spiral-ascending track structure. Its special spiral shape allows the planetary carrier 6 to rise orderly along the track during vibration. It is made of metal, which has good wear resistance and stability. The feed end of the linear vibratory track 22 is tightly connected to the discharge end of the vibratory feeder 21 by bolts or welding, ensuring that the planetary carrier 6 can smoothly transition from the vibratory feeder 21 to the linear vibratory track 22.

[0013] Reference Figure 1 and Figure 2The linear vibrating track 22 has a material-retrieving station 23 at its discharge end. The linear vibrating track 22 is driven by electromagnetic vibration, causing the planetary carrier 6 to move linearly along the track. Other embodiments may use a motor to drive an eccentric wheel. A limiting block 24 is provided at the material-retrieving station 23 to prevent the planetary carrier 6 from moving. The limiting block 24 is made of rubber to avoid damage to the planetary carrier 6. Other embodiments may use plastic, which provides elasticity and strength. The limiting block 24 is fixed to a specific position at the material-retrieving station 23 by bolts or clips. When the planetary carrier 6 moves to the material-retrieving station 23 along the linear vibrating track 22, the limiting block 24 blocks it, ensuring that the planetary carrier 6 accurately stops at the material-retrieving position.

[0014] Reference Figure 3 and Figure 4 Specifically, in this embodiment, the clamping mechanism 3 consists of a first mechanical claw 31, a second mechanical claw 32, a connecting plate 33, and a linear drive structure 34. The first mechanical claw 31 and the second mechanical claw 32 are horizontally connected by the connecting plate 33, enabling them to move synchronously. The bottom of the connecting plate 33 is provided with a linear drive structure 34, which is a conventional screw and nut transmission mechanism that provides stable linear motion with high precision and speed. The nut of the screw and nut transmission mechanism is fixedly connected to the connecting plate 33 by bolts, and is used to drive the connecting plate 33 to move horizontally and linearly between the picking station 23 and the unloading station.

[0015] Both the first mechanical gripper 31 and the second mechanical gripper 32 are equipped with two gripping rods 35 and a gripping rod drive unit 36 ​​for opening and closing the two gripping rods 35. In this embodiment, the gripping rod drive unit 36 ​​is a conventional small gripper cylinder. The two gripping rods 35 are respectively fixedly installed on the two gripping parts of the small gripper cylinder, so that the opening and closing action of the two gripping rods 35 can be quickly realized. The two gripping rod drive units 36 are installed on the connecting plate 33 by bolts or welding. When the gripping rod drive unit 36 ​​is activated, it drives the two gripping rods 35 to open and close. Furthermore, each gripping rod 35 is provided with an arc-shaped groove 351 that matches the contour of the planetary carrier 6. The design of the arc-shaped groove 351 can better fit the planetary carrier 6 and increase the stability of the gripping. The distance between the first mechanical claw 31 and the second mechanical claw 32 matches the distance between the material picking station 23 and the inspection station 411. When the connecting plate 33 moves to the material picking station 23, the clamping rod drive 36 of the first mechanical claw 31 drives the clamping rod 35 to close, grabbing the planetary carrier 6 of the material picking station 23. Then the linear drive structure 34 drives the connecting plate 33 to move to the inspection station 411 of the torque detection mechanism 4. The first mechanical claw 31 releases the planetary carrier 6 and places it in the inspection station 411 for torque testing. Meanwhile, while the first robotic gripper 31 is gripping the planetary carrier 6 at the material handling station 23, the second robotic gripper 32 waits at the inspection station 411. When the first robotic gripper 31 places the new planetary carrier 6 into the inspection station 411 and completes the inspection, the clamping rod drive 36 of the second robotic gripper 32 drives the clamping rod 35 to close, clamping the planetary carrier 6 that has been inspected at the inspection station 411. Then, as the connecting plate 33 moves to the unloading station of the screening and unloading mechanism 5, the second robotic gripper 32 releases, placing the inspected planetary carrier 6 at the unloading station, thus achieving efficient transfer of the planetary carrier 6.

[0016] Reference Figure 5 and Figure 6 Specifically, in this embodiment, the torque detection mechanism 4 includes a test bench 41, a drive assembly 42, a transmission assembly 43, a measurement and analysis assembly, and a clamping assembly 44. The test bench 41 has a testing station 411 on its top for placing the planetary carrier 6. The drive assembly 42 applies torque; in this embodiment, it is a motor that provides stable torque output, but in other embodiments, it can be a hydraulic motor with a larger torque. The transmission assembly 43 transmits torque. The clamping assembly 44 includes a mounting plate 441, a mounting cylinder 442, a rotating shaft 431, a sleeve 443 fitted onto the rotating shaft 431, and a clamping cylinder 444.

[0017] The drive assembly 42 is connected to the rotating shaft 431 of the transmission assembly 43 via a coupling, transmitting torque to the rotating shaft 431. The mounting plate 441 is fixed to the frame 1 by bolts or welding and is located directly above the test bench 41, serving as support and fixation. It can be made of metal and has high strength. The mounting cylinder 442 passes through the mounting plate 441 and its bottom is located directly above the test bench 41. The mounting cylinder 442 and the mounting plate 441 are connected by bearings or seals to ensure the stability of the mounting cylinder 442. The sleeve shaft 443 passes through the middle of the mounting cylinder 442 in a vertical direction. The sleeve shaft 443 can slide freely in the vertical direction within the mounting cylinder 442. Since the bottom of the sleeve shaft 443 is provided with a clamping cylinder 444 for clamping the edge of the planetary carrier 6, the clamping cylinder 444 is fixedly connected to the sleeve shaft 443 by bolts or welding, which is used to fix the planetary carrier 6 to the testing station 411 of the test bench 41. Both the rotating shaft 431 and the drive assembly 42 are housed within the sleeve shaft 443, allowing the drive assembly 42 to drive the rotating shaft 431 to rotate within the sleeve shaft 443. The rotating shaft 431 then transmits the torque of the drive assembly 42 to the planetary carrier 6. When the planetary carrier 6 is placed at the testing station 411 of the test bench 41, a cylinder at the top of the sleeve shaft 443 drives it to move vertically downward within the mounting cylinder 442, thereby causing the clamping cylinder 444 to descend and clamp the edge of the planetary carrier 6, thus fixing the planetary carrier 6. Then, the drive assembly 42 is activated, transmitting torque to the planetary carrier 6 via the rotating shaft 431. The measurement and analysis assembly collects and analyzes data in real time. The drive assembly 42, transmission assembly 43, measurement and analysis assembly, and clamping assembly work together to complete the torque test of the planetary carrier 6.

[0018] The measurement and analysis component collects and processes torque and angle data in real time. This component is a combination of a torque sensor and a data analysis module. The torque sensor accurately collects data, while the data analysis module processes and analyzes it. The torque sensor is embedded in the rotating shaft 431, monitoring its torque and angle data in real time and transmitting the data to the data analysis module. The data analysis module displays the data through a human-machine interface and feeds the results back to the control system, enabling the control system to precisely control the detection process.

[0019] Reference Figure 7Specifically, in this embodiment, the sorting and unloading mechanism 5 includes a qualified product guide structure 51, a defective product guide structure 52, a movable base 53, and a sliding drive structure 54. The qualified product guide structure 51 and the defective product guide structure 52 are respectively disposed on both sides of the sorting base 53 and are both fixedly connected to the base 53 by bolts or welding. The sliding drive structure 54 can be a conventional screw and nut transmission structure with high precision. The base 53 is fixedly connected to the nut of the sliding drive structure 54, and the sliding drive structure 54 drives the base 53 to move. The control system controls the qualified product guide structure 51 or the defective product guide structure 52 to move to the unloading station to receive the planetary carrier 6 based on the detection result of the torque detection mechanism 4. Both the qualified product guide structure 51 and the unqualified product guide structure 52 are pipe structures with their openings facing upwards. When the test result is qualified, the control system sends a signal to the sliding drive structure 54, which drives the base 53 to move, so that the pipe of the qualified product guide structure 51 moves directly below the unloading station with the pipe opening facing the unloading station. When the test result is unqualified, the control system sends a signal to the sliding drive structure 54, which drives the base 53 to move, so that the unqualified product guide structure 52 moves directly below the unloading station with the pipe opening facing the unloading station.

[0020] The implementation principle of this embodiment is as follows: When the planetary carrier torque detection device of this embodiment is working, the vibrating plate 21 of the feeding mechanism 2 causes the planetary carrier 6 to rise along the spiral track and enter the linear vibrating track 22, through which it is transported to the material picking station 23 and blocked and positioned by the limiting block 24; the linear drive structure 34 of the clamping mechanism 3 drives the connecting plate 33, so that the first mechanical claw 31 grabs the planetary carrier 6 at the material picking station 23, moves it to the detection station 411 of the torque detection mechanism 4 and then releases it, while the second mechanical claw 32 waits at the detection station 411. After the detection is completed, the second mechanical claw 32 grabs... In the planetary carrier 6 and torque detection mechanism 4, the drive component 42 transmits torque to the planetary carrier 6, which is fixed by the clamping component on the detection station 411, through the transmission component 43. The measurement and analysis component collects torque and angle data in real time and feeds it back to the control system. The screening and unloading mechanism 5, based on the signal issued by the control system according to the detection results, drives the base 53 to move via the sliding drive structure 54, causing the qualified product guide structure 51 or the unqualified product guide structure 52 to move to the unloading station to receive the planetary carrier 6. This achieves an automated process for the planetary carrier 6 from feeding to detection to screening and unloading. Compared with existing technologies, this reduces manual intervention, improves detection efficiency and accuracy, and meets the requirements of modern industry for efficient and accurate torque detection of the planetary carrier 6.

[0021] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
