[0042] The inner end section assembly mechanism 201 on the external spline sleeve assembly unit 2 is an automated assembly line for assembling the inner end section with corresponding accessories such as dust covers, differential springs, etc. Before the half-shaft is assembled on the sleeve, an automatic barcode scanner is used to scan the QR code on the sleeve, and eddy current detection is performed to check the internal quality of the sleeve. The sleeve reaches the second station of the barcode scanner / eddy current detection unit through a conveyor belt or a conveying mechanism. The barcode scanner automatically recognizes the QR code. At the same time, the eddy current detection equipment checks whether the internal structure of the sleeve has defects. The inspected sleeve is placed on the turntable for subsequent assembly. The inspected sleeve is sent to the turntable feeding mechanism 2 by the conveying mechanism, and is placed in an appropriate position on the turntable by a robot or an automated device. Then, the MMC size of the sleeve is detected by the MMC and retaining ring groove detection mechanism. Whether the inner diameter, outer diameter, etc. and the size of the retaining ring groove meet the design requirements, the corresponding measuring equipment or visual inspection system performs dimensional inspection in this process, and then the dust cover is sent to the assembly position of the sleeve through the dust cover feeding mechanism, the manipulator grabs the dust cover, and presses it onto the sleeve through the dust cover pressing mechanism, and the pressing force and displacement curve are recorded during the pressing process. In this process, the differential spring is placed on the sleeve through the automatic feeding mechanism or manually, and the differential spring in place detection mechanism ensures that the differential spring is correctly placed in the specified position of the sleeve.

After the installation is completed, it is transported to the sliding sleeve pre-installation mechanism 308, and the sliding sleeve pre-installation mechanism 308 is used. It is responsible for pre-installing the sleeve onto the shaft rod, preparing for the subsequent assembly work, ensuring the accurate pre-installation and fixation of the sleeve, and then entering the middle position assembly mechanism 309 process, through which the middle position assembly mechanism 309 is responsible for the middle position assembly work, assembling different parts together, and after the middle position assembly mechanism 309 is completed, it is transported to the outer end large clamp feeding and installation mechanism 310, and the outer end large clamp feeding and installation mechanism 310 is responsible for installing the outer end large clamp onto the shaft rod, ensuring the accurate installation and connection of the large clamp, and after the half-axle large clamp is installed, it is transported to the automatic In the process of labeling mechanism 311, the automatic labeling mechanism 311 is responsible for automatically labeling the assembly, marking and tracking, ensuring accurate labeling and identification.

Each workstation uses precise mechanical devices and control systems, which can operate continuously and stably without frequent human intervention, thus greatly shortening the production cycle, meeting the urgent needs of large-scale production, and reducing the possibility of human errors. Each assembly step is performed by precise machines, ensuring precise control of assembly dimensions and forces. This has greatly improved the consistency of product quality, and each half-axle assembly can meet the design requirements, avoiding performance fluctuations caused by improper human operation.
