[0017] Example 1

[0018] This embodiment provides Figure 1 and Figure 2 A tooling fixture for expanding ring processing shown in the figure includes a base 1, which is composed of a horizontal conical handle 11 and a vertical positioning plate 12. The handle end on the left side of the conical handle 11 is fixedly connected to the middle of the left side surface of the positioning plate 12. A groove 2 for placing the expanding ring is provided in the middle of the right side of the positioning plate 12. A fixing component 3 for fixing the expanding ring is provided on the right side of the positioning plate 12, wherein through holes are provided at the center of the positioning plate 12 and the conical handle 11 to fix both on the lathe equipment.

[0019] When in use, first install the parts on the fixture, and then place the expansion ring to be processed in the groove 2 on the positioning plate 12, and fix the expansion ring tightly on the positioning plate 12 of the base 1 through the fixing component 3. After placing, place the base 1 horizontally as a whole and fix it on a lathe or other equipment, and then grind and polish the inside of the expansion ring through the lathe, thereby solving the problem that the expansion ring cannot be well fixed during each processing, causing the expansion ring to shake during the grinding and polishing process, thereby improving the qualified rate of the final product processed and improving work efficiency.

[0020] Furthermore, the fixing assembly 3 includes a plurality of pressure plates 31, which are arranged on the right side of the positioning plate 12 around the center circumference of the positioning plate 12. Screw holes 32 corresponding to the plurality of pressure plates 31 are horizontally opened on the right side of the positioning plate 12. A bolt 33 is threadedly connected to each screw hole 32, and the bolt 33 passes through the pressure plate 31 for sliding connection.

[0021] Through the provided screw holes 32, the bolts 33 can tightly fix the pressure plate 31 on the positioning plate 12 to form a whole, so that the pressure plate 31 can tightly fix the expansion ring on the positioning plate 12, increase stability, avoid shaking of the expansion ring during processing, and thus improve the qualified rate of the finished product.

[0022] Furthermore, a protection ring 4 is provided between the positioning plate 12 and the plurality of pressure plates 31 .

[0023] The protective ring 4 is provided to prevent the pressing plate 31 from directly contacting the expansion ring, thereby preventing the pressing plate 31 from being pressed too tightly and causing damage to the expansion ring.

[0024] Furthermore, four pressing plates 31 are provided, and one end of the four pressing plates 31 close to the groove 2 is pressed on the edge of the protection ring 4 .

[0025] By providing four pressing plates 31 , the pressing plates 31 can evenly fix the expansion ring from four directions, so that the pressing plates 31 are evenly stressed, and in combination with the protective ring 4 , the protection of the expansion ring is improved to prevent the expansion ring from being damaged.

[0026] Furthermore, a washer 5 is provided between the nut of each bolt 33 and the pressing plate 31 , and the washer 5 is sleeved on the bolt 33 and slidably connected.

[0027] The washer 5 provided can be used to protect the pressure plate 31 so that the bolts 33 will not cause damage to the surface of the pressure plate 31 when fixing the pressure plate 31, disperse the pressure of the bolts 33 on the pressure plate 31, increase the fixing area of ​​the bolts 33 on the pressure plate 31, and improve the stability of the expansion ring of the pressure plate 31.
