[0029] The present application embodiment discloses a carbon-carbon support ring acupuncture auxiliary tooling. Figure 1 and Figure 2 A carbon-carbon support ring needle-punching auxiliary tooling includes a material receiving ring 1 and a positioning component 2. The positioning component 2 is arranged on the material receiving ring 1. A fixing hole 11 is arranged through the middle position of the material receiving ring 1. The material selected for the material receiving ring 1 in the embodiment of the present application is plastic foam, so that the material receiving ring 1 has durability and is not easy to be damaged, and has the ability to maintain its shape during long-term use, thereby increasing the service life of the material receiving ring 1 when it is needle-punctured, and when the material receiving ring 1 is needle-punctured, it is not easy to deform which affects the processing, thereby making the service life of the material receiving ring 1 better.

[0030] Reference Figure 1 and Figure 2 The positioning assembly 2 includes a fixed disk 21, which is circular and penetrates and is snap-fitted into the fixed hole 11. In the embodiment of the present application, the fixed disk 21 and the receiving ring 1 are cut and produced at one time from the same material, so that the fit between the fixed disk 21 and the fixed hole 11 is better, and there is no need to reduce the dimensional error range of the fixed disk 21 during processing, so that the production of the fixed disk 21 is simpler and more convenient.

[0031] Reference Figure 1 and Figure 2 The positioning assembly 2 also includes a positioning disk 22, which is circular. The diameter of the positioning disk 22 is equal to the inner diameter of the support ring to be processed. The positioning disk 22 is coaxially fixed on one side of the fixed disk 21. In the embodiment of the present application, when the positioning disk 22 is fixedly connected to the fixed disk 21, the selected adhesive material is adhesive glue, and the diameter of the positioning disk 22 is larger than the diameter of the fixed disk 21. When the fixed disk 21 is inserted into the fixing hole 11, the positioning disk 22 abuts against the receiving ring 1 and covers a part of the area of ​​the receiving ring 1. In the embodiment of the present application, the position of the receiving ring 1 not covered by the positioning disk 22 is used for receiving the material for processing the support ring. In the embodiment of the present application, the material selected for the positioning disk 22 is plastic foam, so that the positioning disk 22 is durable and not easy to break, and also has the ability to maintain its shape during long-term use, thereby improving the service life of the positioning disk 22.

[0032] At the same time, the fixed connection between the positioning disk 22 and the fixed disk 21 allows the positioning disk 22 to be quickly positioned when the positioning disk 22 needs to be set on the receiving ring 1 through the cooperation of the card machine between the fixed disk 21 and the fixed hole 11, thereby making the positioning of the positioning disk 22 simpler and more convenient, thereby making it faster to use. At the same time, the setting of the fixed disk 21 makes the position between the positioning disk 22 and the receiving ring 1 more stable.

[0033] Reference Figure 1 and Figure 2 A center hole 23 is provided in the middle of the positioning disk 22, so that when the positioning disk 22 needs to be separated from the receiving ring 1, the user can insert a finger or a tool into the center hole 23, and then separate the positioning disk 22 from the receiving ring 1 through the center hole 23, thereby making the separation between the positioning disk 22 and the receiving ring 1 simpler and more convenient.

[0034] Reference Figure 1 and Figure 2 The positioning disk 22 includes a main body 221 and a plurality of positioning portions 222. The main body 221 is circular, and the positioning portions 222 are circular rings with different diameters. The positioning portions 222 are sequentially sleeved on the main body 221, and the diameters of the sides where two adjacent positioning portions 222 abut against each other are the same. The arrangement of the plurality of positioning portions 222 allows the positioning rings away from the main body 221 to be separated from the main body 221 when supporting rings of different diameters need to be processed. The diameter of the positioning disk 22 meets the size processing requirements of the supporting ring, thereby making the positioning disk 22 suitable for positioning and molding of supporting rings of various sizes.

[0035] Reference Figure 1 and Figure 2 The thickness of the positioning plate 22 is not less than 15 mm. In the embodiment of the present application, the thickness of the positioning plate 22 is 15 mm, so that the positioning plate 22 has a larger positioning thickness range for the support ring, so that the positioning plate 22 can position support rings of different thicknesses, thereby making the positioning effect of the positioning plate 22 better.

[0036] Reference Figure 1 and Figure 2The positioning assembly 2 also includes a pressure plate 24, which is circular and has a through-hole in the middle of the pressure plate 24. The diameter of the pressure hole is the same as the diameter of the positioning plate 22. When the positioning plate 22 is inserted into the pressure hole, the pressure plate 24 presses the material, so that when the positioning plate 22 positions the material, the positioning plate 22 is inserted into the pressure hole, and the pressure plate 24 presses the material. When the material is pressed and the positioning plate 22 needs to be taken out for processing, the positioning plate 22 is taken out through the pressure hole by a tool or a finger, and when the positioning plate 22 is taken out, the pressure plate 24 is always kept pressing the material, so that when the positioning plate 22 is taken out, the shape of the pressed material is always stable, and then the pressure plate 24 is removed to perform acupuncture on the material.

[0037] The implementation principle of a carbon-carbon support ring needling auxiliary tooling in an embodiment of the present application is as follows: when the support ring needs to be processed and manufactured, a material receiving ring 1 is set on the positioning plate 22, and then the material is evenly laid along the edge of the positioning plate 22 and fixed by hand. When the laying is completed, the positioning plate 22 is separated from the material receiving plate, and the material is needled at this time. Then, each layer is repeatedly positioned and laid by the positioning plate 22, and the support ring forming process is repeated, so as to keep the material position accurate, and then the thickness of the support ring preform product is continuously increased, so that the contour shape of the support ring preform is formed in one time, which improves the problem that for large-sized support rings, the waste material cut out is too large, the material waste is serious, and the economy is poor.
