With the development of the automotive industry, higher requirements are placed on the position detection of double planetary gears to ensure the reliability of the gears during operation. In order to improve the safety and stability of the automotive transmission system, the position of the double planetary gears must be accurately measured so that potential problems can be discovered and corrected in a timely manner to ensure the quality of the vehicle.

The third linear drive member 48 drives the sliding seat 46 and the second detection module 47 to move toward the axis direction of the expansion sleeve positioning assembly 20, so that the detection end of the measuring probe 471 contacts the measuring tooth 52 of the duplex planetary gear 50 to be measured, thereby accurately measuring its position. In this embodiment, a driving elastic member 49 is also provided between the mounting seat 42 and the second detection module 47. The driving elastic member 49 is a coil spring or a coil tension spring. The driving elastic member 49 is used to assist the measuring probe 471 to move toward the reference tooth 51 of the duplex planetary gear, so that the measuring probe 471 is pressed against the measuring tooth 52 of the duplex planetary gear 50 to be measured, thereby ensuring the accuracy of the detection data.

[0054] The implementation principle of this embodiment is as follows: the detection equipment in this application is intended to automatically measure the position of the large and small teeth of the duplex planetary gears. When in use, it is only necessary to place the duplex planetary gear 50 to be tested on the expansion sleeve positioning assembly 20, press the start button, and the expansion sleeve positioning assembly 20 can automatically tighten the duplex planetary gear 50 to be tested and position the center, maintain the center of the duplex planetary gear 50 to be tested, and then move the reference tooth positioning probe 351 to contact the reference tooth 51 of the duplex planetary gear 50 to be tested, and move the measuring probe 471 to contact the measuring tooth 52 of the duplex planetary gear 50 to be tested. The measurement is completed and the results are recorded for automatic identification of its position and product quality judgment.

[0055] The detection equipment in the present application can perform automated measurement of duplex planetary gears. Each measurement uses the expansion sleeve positioning assembly 20's own component reference for center positioning, ensuring the measurement accuracy. The entire detection process has a high degree of automation, and the collected data can be automatically saved and analyzed by a computer, effectively reducing the operator's workload and improving the measurement accuracy and efficiency of the duplex planetary gear position.

[0056] The first detection module 35 and the second detection module 47 in the present application can both use bidirectional sensors to measure the position of the gear 52; as an alternative, the first linear drive component 25, the second linear drive component 36 and the third linear drive component 48 in the present application can also be a combination structure composed of a hydraulic cylinder or a linear motor or a motor screw nut.

[0057] The detection device in the present application can also add a data processing module, and the data processing module is integrated into the system of the detection device, so that the measurement data can be processed in real time to improve the accuracy of the measurement results. The data processing module includes a data acquisition unit, a data processing unit and a data storage unit. The data acquisition unit is used to collect data of the measuring probe 471 in real time, the data processing unit is responsible for processing the collected data to ensure the accuracy and consistency of the data, and the data storage unit is used to save the processed data. The data processing module further improves the reliability and accuracy of the measurement results by processing and saving data in real time.

The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
