The annular part 4 is placed on the support platform 5 to support it, and then installed on the annular base 3 by the pressure ring plate 2. Thus, the annular part 4 can be clamped and fixed on the support platform 5. The pressure ring plate 2 can expose the upper surface or the two sides of the annular part 4, so that multiple sets of clamps are not needed to hold it, preventing the clamps from interfering with the processing equipment, and the complete processing of the annular part 4 can be completed.

[0032] Specifically, a first limiting groove 11 is provided on the upper surface of the base 1 located inside the annular base 3, and a second limiting groove 12 is provided on the upper surface of the base 1 located outside the annular base 3.

[0033] In this embodiment, a first limiting groove 11 and a second limiting groove 12 are respectively provided on the upper surface of the base 1 on both the inner and outer sides of the annular base 3. The first limiting groove 11 and the second limiting groove 12 are only annular to provide installation limit for the pressure ring plate 2.

[0034] Specifically, the pressure ring plate 2 includes a first pressure plate 6; the lower surface of the first pressure plate 6 is provided with a first limiting block 61 that fits into the first limiting groove 11, and the first pressure plate 6 is placed on the annular base 3 inside the support platform 5 so that the first limiting block 61 is embedded in the first limiting groove 11.

[0035] The outer top of the first pressure plate 6 is provided with a ring-shaped first flange 62, which overlaps the ring-shaped part 4.

[0036] A first threaded hole 31 is provided on the outer side of the annular base 3, and a first through hole 63 is provided on the first pressure plate 6 to fit the first threaded hole 31. The bolt passes through the first through hole 63 and is threadedly connected to the first threaded hole 31.

[0037] In this embodiment, the annular part 4 is placed on the support platform 5 to support the annular part 4. The first pressure plate 6 is placed on the annular base 3 inside the support platform 5. The outer diameter of the first pressure plate 6 is adapted to the inner diameter of the support platform 5.

The bolt passes through the second through hole 73 and is threadedly connected to the second threaded hole 32.

[0042] In this embodiment, the annular part 4 is placed on the support platform 5 to support the annular part 4, and the second pressure ring 7 is placed on the annular base 3 outside the support platform 5. The inner diameter of the second pressure ring 7 is adapted to the outer diameter of the support platform 5. At the same time, the second limiting block 71 is embedded in the second limiting groove 12, and the second limiting groove 12 provides position positioning for the second pressure ring 7. After positioning, the second pressure ring 7 is installed on the annular base 3 by bolts passing through the second through hole 73 and threadedly connecting to the second threaded hole 32.

[0043] The second flange 72 is located at the top of the inner circular side surface of the second pressure ring 7. The second flange 72 is annular, so that when the second pressure ring 7 is installed on the annular base 3, the second flange 72 can clamp the annular part 4 on the support platform 5.

[0044] Optionally, the widths of the first flange 62 and the second flange 72 can be set as needed.

[0045] The first pressure plate 6 can be installed only, which can expose the outer machined surface of the annular part 4. The upper machined surface of the annular part 4 can be exposed or not by setting the width of the first flange 62.

[0046] The second pressure ring 7 can be installed only, which can expose the inner machined surface of the annular part 4. The upper surface machined surface of the annular part 4 can be exposed or not by setting the width of the second flange 72.

[0047] The first pressure plate 6 and the second pressure ring 7 can be installed simultaneously. The upper surface of the annular part 4 can be exposed by setting the width of the second flange 72.
