Description

Technical Field

[0001] This invention relates to the field of anti-lock braking assembly technology, and in particular to an eccentric wheel feeding device and pressing equipment for eccentric shaft assemblies. Background Technology

[0002] like Figure 18 As shown, the existing eccentric shaft assembly for anti-lock braking systems includes an eccentric wheel 7, a drive shaft 8, and a bearing 9. The drive shaft 8 is press-fitted into the eccentric hole of the eccentric wheel 7; the bearing 9 is press-fitted onto the eccentric wheel 7. Currently, the press-fitting process of the eccentric shaft assembly requires two steps. The first step is the press-fitting between the eccentric wheel 7 and the drive shaft 8. The two parts are manually placed into the press-fitting station, then pressed using a press-fitting machine, and finally removed manually. The second step is the press-fitting between the drive shaft 8 and the bearing 9. Again, the two parts are manually placed into the press-fitting station, then pressed using another press-fitting machine, and finally removed manually. This manual loading and positioning is very labor-intensive and time-consuming. Furthermore, the two processes are located in two different work areas. The assembled eccentric wheel 7 and drive shaft 8 need to be manually transported to the bearing 9 between the two areas before the bearing 9 is assembled. The transportation in between consumes manpower and resources, which greatly reduces production efficiency and ultimately results in low production efficiency of the eccentric shaft assembly, affecting the overall economic benefits of production.
