The slide rail plates 5 are fixed to the left and right ends of the lower part of the movable auxiliary plate 6. The lower ends of the tapered grinding wheel 16 and the outer cylindrical grinding wheel assembly 10 are both fixed to the movable auxiliary plate 6, which has the effect of limiting the movable auxiliary plate 6 when it moves, thereby improving the stability of the movable auxiliary plate 6.

[0030] As a further implementation scheme of this scheme, one end of the threaded rod 19 is rotatably connected to the inner side of the left end of the grinding machine worktable 1, a threaded hole is opened on the inner side of the lower end of the lower screw hole slide plate 20, the lower end of the lower screw hole slide plate 20 is slidably connected to the upper end of the grinding machine worktable 1, the chuck 22, the tapered grinding wheel 16 and the inner grinding head assembly 9 are in the same horizontal plane, so that the lower screw hole slide plate 20 drives the second servo motor 21 and the chuck 22 to move, the position of the part can be adjusted, and the angle of the part can be adjusted at the same time.

[0031] Working process: During the use of the device, the external power supply is energized. When the part needs to be processed, the part is fixed on the existing chuck 22, and the first servo motor 18 is started. The first servo motor 18 drives the spirally connected lower screw hole slide plate 20 to move through the threaded rod 19. The lower screw hole slide plate 20 is slidably connected to the upper end of the grinding machine worktable 1, which has the effect of limiting when the upper mounting table 3 moves. The movement of the lower screw hole slide plate 20 drives the second servo motor 21 and the chuck 22 to move, so as to adjust the position of the part. The chuck 22 is driven to rotate by the second servo motor 21, so that the angle of the part can be adjusted. After the two parts move to one end of the outer cylindrical grinding wheel assembly 10, the feed linear motor 2 is started, and the feed linear motor 2 drives the movable auxiliary plate 6 to move. The movable auxiliary plate 6 slides on the slide groove 4 through the slide plate 5. The slide plate 5 and the slide groove 4 have the effect of limiting the moving direction of the movable auxiliary plate 6. The movement of the movable auxiliary plate 6 drives the upper end outer cylindrical grinding wheel assembly 10 and the inner grinding head assembly 9 to move. When the outer cylindrical grinding wheel assembly 10 contacts the part , the parts are ground by the outer grinding wheel assembly 10. When the inside of the parts needs to be ground, the parts are aligned with the grinding heads of the inner grinding head assembly 9 according to the above principle, and the cylinder 11 is started. One end of the cylinder 11 slides inside the cylindrical movable hole 13, and the threaded rod 19 pushes the fixed block at the lower end of the inner grinding head assembly 9 to move, and the inner grinding head assembly 9 moves. The inner grinding head assembly 9 pulls the reset spring 15 to deform. At this time, the inner grinding head assembly 9 moves, and the inner grinding head assembly 9 is slidably connected with the embedded slide rail 7 through the track mounting plate 8. When the inner grinding head assembly 9 moves, the inner grinding head assembly 9 is connected to the embedded slide rail 7 through the track mounting plate 8. When the rear end of the head assembly 9 protrudes out of the rear end of the outer cylindrical grinding wheel assembly 10, the parts can be ground. After the grinding is completed, the cylinder 11 contracts and the inner grinding head assembly 9 is reset under the pulling force of the reset spring 15. After the inner grinding head assembly 9 contacts with the rubber buffer column 14, the rubber buffer column 14 is deformed, and the rubber buffer column 14 has the effect of buffering the inner grinding head assembly 9. Based on the above principle, the parts are aligned with the tapered grinding wheel 16 or the turning tool assembly 17, and the parts are ground by the tapered grinding wheel 16 and cut by the turning tool assembly 17.
