[0025] The outer ring is placed above the bottom strip 13. The two groups of blocks 14 realize the preliminary positioning of the outer ring under the action of the corresponding springs 19, while the outer ring is in the middle of the bottom strip 13. Then the pressure plate 9 is moved. The pressure plate 9 and the top sleeve 11 slide along the outer wall of the fixing rod 12 until the pressure plate 9 is pressed on the top of the outer ring. The positioning rod 11 on the top sleeve 10 is combined with the screw hole 17 at the corresponding position to fix the pressure plate 9. Then the base frame 6 is pushed by the push cylinder 2. The base frame 6 drives the drill bit to gradually contact the outer ring, thereby realizing the drilling of the outer ring. While realizing the normal drilling of the outer ring, the stability of the outer ring is guaranteed by the pressure plate 9 in cooperation with the two groups of blocks 14, thereby improving the stability of the bearing outer ring drilling device.

[0026] Specifically, Figure 2 and Figure 4 As shown, the inner wall of the support plate 5 is slidably connected to the outer wall of the vertical end of the base frame 6, and the inner wall of the support plate 5 is screwed with a positioning rod 7, which is screwed with the inner wall of the vertical end of the base frame 6 through a screw hole 8. There are multiple groups of screw holes 8 and screw holes 17, and the spacing between two adjacent groups of multiple groups of screw holes 8 and screw holes 17 is the same. The vertical position of the support plate 5 can be adjusted by combining the positioning rod 7 with screw holes 8 at different positions.

The two sets of blocks 14 realize the preliminary positioning of the outer ring under the action of the corresponding springs 19. At the same time, the outer ring is in the middle of the bottom strip 13. Then move the pressure plate 9. The pressure plate 9 and the top sleeve 11 slide along the outer wall of the fixing rod 12 until the pressure plate 9 is pressed on the top of the outer ring. Then combine the positioning rod 11 on the top sleeve 10 with the screw hole 17 at the corresponding position to fix the pressure plate 9. Then push the bottom frame 6 through the push cylinder 2. The bottom frame 6 drives the drill bit to gradually contact the outer ring, thereby realizing the drilling of the outer ring, so as to realize the normal drilling of the outer ring. At the same time, the stability of the outer ring is ensured by the pressure plate 9 in cooperation with the two groups of blocks 14, thereby improving the stability of the bearing outer ring punching device. The vertical position of the support plate 5 can be adjusted by combining the positioning rod 7 with the screw holes 8 at different positions. At the same time, the spacing between the multiple groups of screw holes 8 and the screw holes 17 is the same, so that the pressure plate 9 can position the outer rings at different heights, and the position of the drill bit can be adjusted quickly accordingly, so that the drill bit is always in the middle position of the outer ring, so that the drilling processing of the outer rings at different heights can be realized, thereby improving the application range of the bearing outer ring punching device.
