Description

Technical Field

[0001] This application relates to the field of motor testing technology, and in particular to a motor gear runout testing device. Background Technology

[0002] Motor gears are key components in electric motor transmission systems, used to transmit power and regulate speed and torque. They are widely used in machinery, automation, automobiles, robotics, and other fields. The quality of motor gears directly affects the transmission efficiency, noise, lifespan, and reliability of the motor system; therefore, testing is crucial.

[0003] Motor gear runout testing refers to the process of measuring the axial or radial offset (i.e., runout) of motor gears during rotation. Runout reflects the smoothness and accuracy of gear rotation and is an important indicator for evaluating gear manufacturing and assembly quality. Excessive runout can lead to unstable gear transmission, increased noise, accelerated wear, and even affect the performance and lifespan of the entire motor. Existing technologies typically only allow for individual testing, resulting in low efficiency. Therefore, this application proposes a motor gear runout testing device. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this application is to provide a motor gear runout detection device to solve the technical problems in the background art.

[0005] The above-mentioned objective of this application is achieved through the following technical solution: a motor gear runout detection device, including a frame and a pair of transport components at the upper end, each pair of transport components is provided with a detection station for placing the motor to be tested at the upper end, the two ends of the transport components are provided with line scanning lasers fixedly connected to the frame, and the end of the transport components is provided with a gripping component for clamping and unloading.

[0006] By adopting the above technical solution, the motor is transferred to the inspection station. The fixture is equipped with contact pins. After the product is placed, it is powered on and rotates. The rotation of the gear can be controlled by the contact pins contacting the motor gear, preparing for subsequent inspection. In this application, motor gears at two inspection stations can be inspected simultaneously or sequentially, significantly improving inspection efficiency. The design of the transport component allows the motor to be inspected to be delivered to the inspection station quickly and accurately, reducing waiting time and further improving the overall inspection speed. To ensure inspection accuracy, the line-scanning lasers at both ends of the transport component can accurately measure the runout of the motor gear during rotation, ensuring inspection accuracy. The use of line-scanning lasers avoids human error that may exist in traditional inspection methods, improving the reliability of inspection results. To achieve automated operation, the design of the transport component and gripping component realizes automatic loading, inspection, and unloading of motor gears, reducing manual intervention and improving the level of production automation. Automated operation not only reduces labor intensity but also reduces inspection errors caused by human factors, improving production efficiency and product quality.

[0007] Furthermore, the transport component is provided with a pair of inspection stations, and a transport plate is provided at the bottom of the inspection station.

[0008] By adopting the above technical solution, the detection tasks of two motor gears can be processed simultaneously, effectively improving the detection efficiency.

[0010] By adopting the above technical solution, in this application, the movable plate is slidably connected to the transport track, and the specific driving method can be motor-driven belt-driven or electric cylinder-driven.

[0011] Furthermore, the gripping assembly includes a pair of support frames fixedly connected to the frame. The upper ends of the pair of support frames are fixedly connected to the drive rail. Drive shafts are rotatably mounted at both ends of the drive rail. A drive motor for driving the drive shafts is mounted on the drive rail. A drive belt is sleeved between the drive shafts.

[0013] By adopting the above technical solution, the drive motor drives the drive shaft, which in turn drives the drive belt to rotate, allowing the translation frame to move left and right. At the same time, by setting up the electric cylinder, the pneumatic gripper can move up and down, thus better completing the clamping task.

[0014] Furthermore, the bottom of the drive rail is provided with a qualified product transport frame and a defective product transport frame. A qualified product transport belt is fitted on the outside of the qualified product transport frame, and a defective product transport belt is fitted on the outside of the defective product transport frame. One side of the qualified product transport frame is fixedly connected to a qualified product transport drive frame, and a qualified product motor for driving the qualified product transport belt is fixedly installed on the qualified product drive frame. One side of the defective product transport frame is fixedly connected to a defective product transport drive frame, and a defective product motor for driving the defective product transport belt is fixedly installed on the defective product drive frame.

[0023] The present application will be further described in detail below with reference to the accompanying drawings.

[0024] Example, refer to Figure 1 as well as Figure 2 A motor gear runout detection device includes a frame 1 and a pair of transport components at the upper end. Each pair of transport components is provided with a detection station 3 for placing the motor to be tested at the upper end. Line scan lasers 2 are fixedly connected to the frame 1 at both ends of the transport components. A gripping component for clamping and unloading is provided at the end of the transport components.

[0025] The motor is transferred to inspection station 3. The fixture contains contact pins. After the product is placed, it is powered on and rotates. The rotation of the gear is controlled by the contact pins contacting the motor gear, preparing for subsequent inspection. In this application, motor gears on two inspection stations 3 can be inspected simultaneously or sequentially, significantly improving inspection efficiency. The design of the transport component allows the motor to be inspected to be quickly and accurately delivered to inspection station 3, reducing waiting time and further improving overall inspection speed. To ensure inspection accuracy, the line-scanning lasers 2 at both ends of the transport component can accurately measure the runout of the motor gear during rotation, ensuring inspection accuracy. The use of the line-scanning laser 2 avoids potential human error in traditional inspection methods, improving the reliability of inspection results. The laser sensor, by emitting a laser beam and receiving reflected light, accurately measures the minute displacement (i.e., runout) of the gear during rotation, achieving automated operation. The design of the transport component and gripping component enables automatic loading, inspection, and unloading of motor gears, reducing manual intervention and improving the level of production automation. Automated operation not only reduces labor intensity but also reduces inspection errors caused by human factors, improving production efficiency and product quality.

[0026] In this embodiment, refer to Figure 3 as well as Figure 4 The transport component has a pair of inspection stations 3, and a transport plate 31 is installed at the bottom of the inspection station 3. It can handle the inspection tasks of two motor gears at the same time, effectively improving the inspection efficiency.

[0027] In this embodiment, the transport component includes a transport track 11 fixedly connected to the frame 1, a movable plate 12 slidably connected to the transport track 11, and a transport plate 31 mounted on the movable plate 12. In this application, the movable plate 12 is slidably connected to the transport track 11, and the specific driving method can be motor-driven belt-driven or electric cylinder-driven.

[0028] In this embodiment, the gripping component includes a pair of support frames 21 fixedly connected to the frame 1. The upper ends of the pair of support frames 21 are fixedly connected to the drive rail 22. Drive shafts 24 are rotatably mounted at both ends of the drive rail 22. A drive motor 25 for driving the drive shafts 24 is mounted on the drive rail 22. A drive belt 23 is sleeved between the drive shafts 24. A translation frame 26 is fixedly mounted on the drive belt 23. A connecting plate 33 is mounted on the translation frame 26. A pair of pneumatic grippers 32 are fixedly mounted at the bottom of the connecting plate 33. A telescopic device for driving the pneumatic grippers 32 up and down is mounted on the translation frame 26. The telescopic device includes a push cylinder 34 fixedly connected to the translation frame 26. A docking plate 35 is fixedly mounted at the output end of the push cylinder 34. The docking plate 35 and the connecting plate 33 are fixedly connected.

[0029] The drive motor 25 drives the drive shaft 24, which in turn drives the drive belt 23 to rotate, allowing the translation frame 26 to move left and right. At the same time, by pushing the electric cylinder 34, the pneumatic gripper 32 can move up and down, thus better completing the clamping task.

[0030] In this embodiment, a qualified product transport frame 4 and a defective product transport frame 5 are provided at the bottom of the drive rail 22. A qualified product transport belt 41 is fitted on the outside of the qualified product transport frame 4, and a defective product transport belt 51 is fitted on the outside of the defective product transport frame 5. One side of the qualified product transport frame 4 is fixedly connected to a qualified product transport drive frame 43, and a qualified product motor 42 for driving the qualified product transport belt 41 is fixedly installed on the qualified product drive frame 43. One side of the defective product transport frame 5 is fixedly connected to a defective product transport drive frame 53, and a defective product motor 52 for driving the defective product transport belt 51 is fixedly installed on the defective product drive frame 53. In this application, after the motor completes the inspection, it is clamped onto the transport belt of the transport rail by a pneumatic gripper 32. Qualified products are placed on the qualified product transport belt 41, and defective products are placed and clamped on the defective product transport belt 51, and transported separately.

[0031] Specific implementation process: Connect the equipment to a 220V, 50Hz AC power supply, ensuring stable power and power consumption less than 2KVA. Simultaneously, confirm that the equipment installation environment meets requirements, including an ambient temperature between 15 and 35 degrees Celsius, dry and well-ventilated conditions, a flat and firm ground free from significant vibration, and minimal electronic interference. The motor to be tested is placed at the starting end of the transport assembly. The transport track 11 on the transport assembly begins operation, using a motor-driven belt or electric cylinder to move the moving plate 12, which in turn moves the transport plate 31, transferring the motor to the testing station 3. The testing station 3 has a transport plate 31 at its bottom, with contact pins inside the fixture. When the motor is placed on the testing station 3, the contact pins contact the motor gear, energizing it and causing the gear to rotate, preparing for subsequent testing. The line-scan lasers 2 at both ends of the transport assembly begin operation, emitting laser beams and receiving reflected light to accurately measure the minute displacement (i.e., runout) of the motor gear during rotation, ensuring testing accuracy. The use of the line-scan laser 2 avoids potential human error in traditional testing methods, improving the reliability of the test results. Based on the detection results of the line-scan laser 2, the system determines whether the motor gear is qualified. If qualified, it is marked as OK; if unqualified, it is marked as NG. After the inspection is completed, the gripping assembly starts working. The drive motor 25 drives the drive shaft 24, causing the drive belt 23 to rotate, and the translation frame 26 moves left and right accordingly. At the same time, it pushes the electric cylinder 34 to drive the pneumatic gripper 32 to move up and down, accurately clamping the motor. Subsequently, the pneumatic gripper 32 clamps the motor onto the corresponding conveyor belt. Qualified products are placed on the qualified product conveyor belt 41, and defective products are placed on the defective product conveyor belt 51, and then transported separately.

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.
