[0053] In this scheme: a ball bearing outer ring press-fitting device comprises the following steps:

[0054] During the press-fitting operation of the bearing outer ring, the bearing outer ring is pushed toward the lower end of the positioning plate 201 and abutted against it. During the pushing process, the inner side of the bearing outer ring is in a sleeved state and abuts against the outer side of each group of fan-shaped plates 202. The outer ring of the bearing to be pressed is aligned and positioned by the abutment between the upper end of the bearing outer ring and the lower end of the positioning plate 201. In the process of positioning and pushing the bearing outer ring toward the positioning plate 201, the inner ring of the bearing outer ring first abuts against the glass bead body 303 at the front end of the positioning rod 205 on each group of mounting plates 203. During the abutment process, the glass bead body 303 is pushed to shrink toward the inside of the mounting cavity 301 through the abutment between the inner side of the bearing outer ring and the glass bead body 303. After the bearing outer ring is pushed for alignment and positioning, the glass bead body 303 is reset and abutted against the lower end of the aligned and positioned bearing outer ring through the abutment of the squeezing spring 304 (see FIG. 2 ). Fig.11 The outer ring of the bearing is limited after alignment and positioning, and after alignment, positioning and limiting the outer ring of the bearing, the lifting cylinder 105 pushes the pressure head 104 to move toward the workpiece placed on the carrier 102. During the movement, the outer ring of the bearing is pushed by the positioning plate 201 to press the outer ring of the bearing into the inside of the workpiece to complete the press-fitting operation of the outer ring of the bearing. The entire press-fitting process can not only quickly align and position the outer ring of the bearing and limit the position, but also automatically push and press the outer ring of the bearing, thereby ensuring the press-fitting quality of the outer ring of the bearing and improving the press-fitting efficiency of the outer ring of the bearing. After the press-fitting of the outer ring of the bearing is completed, the pressure head 104 and the positioning plate 201 are driven by the lifting cylinder 105 to reset. During the resetting process, the glass bead body 303 and the inner side of the outer ring of the bearing are pushed against each other to separate the fan-shaped plates 202 from the press-fitted outer ring of the bearing;

[0055] During the press-fitting of the bearing outer ring, the driving ring 802 drives the threaded cylinder 801 to rotate. During the rotation of the threaded cylinder 801, the threaded cylinder 801 and the driving ring 803 are lifted and lowered on the outer side of the pressing head 104 through the threaded meshing transmission between the threaded cylinder 801 and the outer side of the pressing head 104 and the connection of the rotating assembly. During the lifting and lowering of the driving ring 803, the connecting transmission of each group of connecting rods 804 and the sliding connection between the sliding groove 701 and the sliding block 702 force each group of sliding blocks 702 and the fan-shaped plate 202 to move closer to or away from each other, and adjust the spacing between each group of fan-shaped plates 202. By adjusting the spacing, it is convenient for each group of fan-shaped plates 202 to perform alignment and positioning operations on the bearing outer rings with different apertures.

[0056] In the process of press-fitting the outer ring of the bearing, the threaded rod 503 is driven to rotate through the driving pin 504. During the rotation of the threaded rod 503, the mutual meshing transmission between the threaded rod 503 and the threaded sleeve 502 causes the lifting plate 501 to be subjected to force and perform lifting and lowering movements. During the lifting and lowering movement of the lifting plate 501, the connection of the telescopic assembly drives each group of mounting plates 203 and the positioning rods 205 on the mounting plates 203 to be lifted and lowered. Through the lifting and lowering adjustment of each group of positioning rods 205, the use position of the glass bead body 303 on the positioning rod 205 is adjusted. Through the position adjustment, it is convenient to perform the limit operation after aligning and positioning the outer rings of bearings of different thicknesses.
