Coolant is added to the grinding area for cooling. When grinding the dynamic ring and the static ring, the dynamic ring and the static ring are respectively placed in two positioning seats 13 in a set of flipping and positioning components, and enter the grinding chamber 2 for grinding along with the sliding plate 4. At this time, another set of flipping and positioning components is clamped and fed by the clamping jaw assembly 6, and the loading work is carried out while grinding. Before the flipping plate 5 flips, the positioning seat 13 is inserted into the dynamic ring and the static ring. At this time, the positioning plug 21 extends outward and fixes the sides of the dynamic ring and the static ring to ensure the stability of the flipping of the dynamic ring and the static ring.

When grinding the moving ring, the connecting plate 9 rotates half a circle. At this time, the end face of the moving ring is parallel to the grinding disc. As the adjusting frame slides close to the grinding disc, the grinding of the moving ring is realized. When processing the end face of the stationary ring, the steps are consistent with those of the moving ring, but the difference is that when processing the right end face of the stationary ring, refer to Figure 7As shown, at this time, the second clamping jaw 28 is in an open state, and the grinding ring disc 11 is directly ground. When the left end face of the stationary ring is processed, the positions of the grinding ring disc 11 and the grinding ring disc 2 12 are changed by rotating the support plate 10.

[0040] See also Figure 2 As shown, the adjustment frame includes a support rod 7 sliding on the top track of the inner cavity of the grinding chamber 2, and a rotating element 8 is installed on the bottom surface of the support rod 7. The driving end of the rotating element 8 is fixed to the connecting plate 9. The use angle of the connecting plate 9 is changed by driving the rotating element 8, thereby facilitating the alignment of the grinding assembly to adjust the grinding end face of the static ring or the dynamic ring.

[0041] See also Figure 2 As shown, after the positioning seat 13 is turned over, the center of the moving ring or the stationary ring is consistent with the center of the corresponding jaw 1 27 and the center of the jaw 2 28 in the corresponding positioning grinding assembly, which facilitates grinding.

[0042] See also Figure 2 , Figure 5 and Figure 6 As shown, the flip alignment component also includes a vacant cavity arranged on the upper surface of the sliding plate 4, the top of the vacant cavity is provided with a slide groove 31, and the interior of the vacant cavity is provided with a transmission screw rod 22 driven by a dual-axis motor, the outer sleeve of the transmission screw rod 22 is provided with a sleeve 23 that slides along the vacant cavity, the top surface of the sleeve 23 is hinged with a transmission rod 24, one end of the transmission rod 24 is hinged with the flip plate 5, the dynamic ring and the static ring are respectively placed in the corresponding flip plate 5, as the sliding plate 4 slides into the grinding cavity 2, the transmission screw rod 22 drives the sleeve 23 to slide in the vacant cavity, at this time, the sleeve 23 slides toward the rotation base point of the flip plate 5, and the transmission rod 24 pushes the flip plate 5 and the sliding plate 4 to rotate, as shown in FIG. Figure 5 As shown, at this time, the flip plate 5 and the sliding plate 4 are in a vertical state, that is, the dynamic ring and the static ring are placed horizontally instead of vertically.

[0043] See also Figure 5As shown, an electric push rod 26 is installed on the upper surface of the flip plate 5, the pushing end of the electric push rod 26 is fixed to the positioning seat 13, and telescopic rods connected to the positioning seat 13 are arranged on both sides of the electric push rod 26.

[0044] See also Figure 3 As shown, the inner cavity of the positioning seat 13 is provided with a transmission screw 17 driven by a dual-axis motor, and the interior of the transmission screw 17 is sleeved with a sleeve plate 18 sliding along its inner cavity, and a push plate 19 is installed inside the sleeve plate 18, one end of the push plate 19 is an inclined portion, and the other end of the push plate 19 is fixed to the positioning plug 21, and the push plate 19 extends into the interior of the sleeve plate 18 and is provided with a fixing ring, and the push plate 19 extends into the interior of the sleeve plate 18 and is sleeved with a spring 20, and the two ends of the spring 20 are respectively fixed to the sleeve plate 18 and the fixing ring; the inner cavity end surface of the positioning seat 13 is provided with a smooth portion 14, and the adjacent end of the smooth portion 14 is provided with a slope 15 and a smooth portion 2 16 in sequence, the smooth portion 2 16 is parallel to the smooth portion 14, the slope 15 is in sliding contact with the inclined portion, and the straight edge at the inclined portion of the push plate 19 is in contact with the smooth portion 1 14 and the smooth part 16 are in sliding contact, the dynamic ring or the static ring is sleeved on the outside of the positioning seat 13, and then the transmission screw 17 drives the sleeve plate 18 to slide within the inner cavity of the positioning seat 13. In this process, the straight edge of the inclined portion of the push plate 19 slides at the smooth part 14. When it reaches the position of the slope 15, the push plate 19 is subjected to pressure due to the push effect of the inclined surface. The fixed ring of the push plate 19 located in the sleeve plate 18 compresses the spring 20, causing the spring 20 to produce elastic deformation. At this time, the positioning block 21 is pushed outward and moves to the edge until the straight edge of the inclined portion of the push plate 19 is in pushing contact with the smooth part 16. The positioning block 21 only slides toward the edge, thereby fixing the side of the dynamic ring or the static ring to prevent the dynamic ring or the static ring from falling off from the positioning seat 13 when the flip plate 5 rotates.

The bidirectional screw 273 and the mounting plate 275 are rotatably arranged, and the upper clamping block 271 and the lower clamping block 272 are in an open state. When grinding the stationary ring, since double-sided grinding is required, the first clamping jaw 27 and the clamping jaw 27 are in an open state. The two jaws 28 work alternately, that is, when grinding one end face of the stationary ring, the two jaws 28 are in the open state, and the rotating grinding ring disc 11 is used to grind the one end face of the stationary ring; through the rotation of the support plate 10, the grinding ring disc 12 reaches the position of the grinding ring disc 11, and the connecting plate 9 rotates half a circle under the rotation of the rotating element 8, and the other end face of the stationary ring is aligned with the grinding ring disc 12, and is fixed by the two jaws 28, while the one jaw 27 is in the open state, that is, the upper clamping block 271 and the lower clamping block 272 move upward and downward respectively, so as to realize the grinding of different surfaces of the stationary ring.
