Its core function is to remove surface defects such as burrs and uneven areas from the silicon carbide radiant tube through mechanical grinding, thereby significantly improving its surface finish and precision. However, in the use of existing silicon carbide radiant tube grinding devices, due to the high brittleness and hollow structure of silicon carbide radiant tubes, cracks are easily generated on the surface or inside during the grinding process. These cracks may propagate during subsequent use, leading to the breakage of the silicon carbide radiant tube, which seriously affects the quality and service life of the silicon carbide radiant tube. Therefore, a silicon carbide radiant tube grinding device is proposed to address the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses a polishing apparatus for silicon carbide radiant tubes. (Refer to...) Figure 2 , Figure 3 and Figure 5 A grinding device for silicon carbide radiant tubes includes a grinding equipment body 1. A fixed frame 2 is fixedly installed inside the grinding equipment body 1. A positioning component 3 is fixedly connected to the surface of the fixed frame 2. A top plate 4 is fixedly connected to one end of the positioning component 3. A lifting component 5 is provided on the surface of the fixed frame 2. Several support components 6 are provided on both sides of the fixed frame 2. Several support components 6 are fixedly connected to a support plate 7. The grinding equipment body 1 also includes a frame, a conveying structure, a transmission structure, and a grinding structure, etc., which are existing technologies and will not be described in detail here.

[0026] The lifting assembly 5 includes a groove 51 formed on the surface of the fixed frame 2. A ramp block 52 is fixedly installed on the bottom of the top plate 4. The surface of the ramp block 52 is slidably connected to the inner cavity of the groove 51. A top block 53 is slidably connected inside the groove 51. The top block 53 and the ramp block 52 are used in conjunction. A bidirectional screw 54 is rotatably connected to one end of the fixed frame 2. One end of the bidirectional screw 54 extends into the inside of the groove 51 and is rotatably connected to the inner cavity of the groove 51. The surface of the bidirectional screw 54 is slidably connected to the inner cavity of the top block 53. The threads on both sides of the surface of the bidirectional screw 54 are opposite.

[0027] By fitting the silicon carbide radiant tube onto the surfaces of the top plate 4 and the support plate 7, and then rotating the bidirectional screw 54, the opposing threads on both sides of the surface of the bidirectional screw 54 cause the two top blocks 53 to move simultaneously. This pushes the inclined plate against the inclined plate, causing the inclined plate to move the top plate 4 upward. The positioning component 3 stabilizes the position of the top plate 4, allowing the top plate 4 to lift the silicon carbide radiant tube upward and support its inner wall. Subsequently, the silicon carbide radiant tube can be ground by the grinding equipment body 1. During the grinding process, the top plate 4 supports the grinding position of the silicon carbide radiant tube, while the support component 6 and the support plate 7 support both sides of the silicon carbide radiant tube, effectively stabilizing its position and preventing it from shaking or shifting.

[0028] Reference Figure 3 and Figure 5 The positioning component 3 includes a positioning sleeve 31 fixedly connected to the surface of the fixing frame 2, a positioning rod 32 fixedly connected to the bottom of the top plate 4, the surface of the positioning rod 32 being slidably connected to the inner cavity of the positioning sleeve 31, and a positioning block 33 fixedly installed at one end of the positioning rod 32, the surface of the positioning block 33 being slidably connected to the inner cavity of the positioning sleeve 31; the slidable connection between the surface of the positioning rod 32 and the inner cavity of the positioning sleeve 31, and the positioning block 33 preventing the positioning rod 32 from separating from the positioning sleeve 31, so that the positioning rod 32 and the positioning sleeve 31 can stabilize the position of the top plate 4 and prevent the top plate 4 from lateral displacement.

[0029] Reference Figure 5 A slider 5301 is fixedly installed at the bottom of the top block 53. A groove 5302 is provided inside the groove 51. The surface of the slider 5301 is slidably connected to the inner cavity of the groove 5302. A first limiting block 5303 is fixedly installed on the surface of the slider 5301. A first limiting groove 5304 is provided on the inner wall of the groove 5302. The inner cavity of the first limiting groove 5304 is slidably connected to the surface of the first limiting block 5303. By sliding the surface of the first limiting block 5303 to the inner cavity of the first limiting groove 5304, the position of the slider 5301 inside the groove 5302 is stabilized, thereby stabilizing the position of the top plate 4 and preventing the top plate 4 from shifting or other issues that could affect the position of the inclined plate.

[0030] Reference Figure 3 and Figure 4The support assembly 6 includes several sleeves 61 fixedly connected to both sides of the fixed frame 2. A support rod 62 is fixedly connected to the side of the support plate 7 opposite to the fixed frame 2. The surface of the support rod 62 is slidably connected to the inner cavity of the sleeve 61. A spring 63 is provided inside the sleeve 61. One end of the spring 63 is fixedly connected to the inner wall of the sleeve 61, and the other end of the spring 63 is fixedly connected to one end of the support rod 62. After the silicon carbide radiant tube is sleeved on the surface of the support plate 7 and the top plate 4, the position of the support rod 62 is stabilized by the sleeves 61, and the spring 63 supports the support rod 62 so that the support rod 62 supports the position of the support plate 7, so that the support plate 7 plays the role of supporting the silicon carbide radiant tube and ensuring the stability of the position of the silicon carbide radiant tube.

[0031] Reference Figure 4 A second limiting block 64 is fixedly installed on the surface of the support rod 62, and a second limiting groove 65 is opened on the surface of the support sleeve 61. The inner cavity of the second limiting groove 65 is slidably connected to the surface of the second limiting block 64. By slidingly connecting the surface of the second limiting block 64 with the inner cavity of the second limiting groove 65, the position of the support rod 62 inside the support sleeve 61 can be effectively stabilized, and the support plate 7 can be prevented from separating from the support sleeve 61.

[0032] Reference Figure 3 The top plate 4 has a first opening 41 on its surface, and a first guide roller 42 is rotatably installed inside the first opening 41. The support plate 7 has a second opening 71 on its surface, and a second guide roller 72 is rotatably installed inside the second opening 71. By setting the first guide roller 42 and the second guide roller 72, the top plate 4 and the support plate 7 can support the position of the silicon carbide radiant tube, while the first guide roller 42 and the second guide roller 72 can avoid affecting the rotation of the silicon carbide radiant tube, so as to ensure that the silicon carbide radiant tube can carry out normal grinding work.

[0033] Working principle: When grinding the silicon carbide radiant tube, the silicon carbide radiant tube is fitted onto the surface of the top plate 4 and the support plate 7. Then, the bidirectional screw 54 is rotated. Through the opposite threads on both sides of the surface of the bidirectional screw 54, the two top blocks 53 move simultaneously. The surface of the first limiting block 5303 slides into the inner cavity of the first limiting groove 5304 to stabilize the position of the slider 5301 inside the groove 5302, thereby stabilizing the position of the top block 53 inside the groove 51. This allows the top block 53 to push the inclined panel, causing the inclined panel to move the top plate 4 upward. The positioning block 33 stabilizes the position of the positioning block 33 inside the positioning sleeve 31, thus stabilizing the positioning assembly 3. The top plate 4 is positioned so that it lifts the silicon carbide radiant tube upwards and supports the inner wall of the tube. The surface of the second limiting block 64 slides into the inner cavity of the second limiting groove 65 to stabilize the position of the support rod 62 inside the support sleeve 61. The spring 63 supports the support rod 62, which in turn supports the support plate 7, thus supporting both sides of the silicon carbide radiant tube and effectively stabilizing its position. Then, the main body 1 of the grinding equipment can be used to grind the silicon carbide radiant tube. During the grinding process, the top plate 4 supports the grinding position of the silicon carbide radiant tube to effectively reduce the risk of cracks.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
