Description

Technical Field

[0001] This invention relates to the field of equipment technology for processing silicon carbide ceramic tubes, specifically to equipment for processing silicon carbide ceramic tubes. Background Technology

[0002] The silicon carbide ceramic tube grinding and polishing equipment is a processing device mainly designed for silicon carbide ceramic tubes. It relies on a polishing head and feed adjustment structure to perform uniform grinding and polishing of the inner wall of the silicon carbide ceramic tube. This equipment can specifically remove various processing defects such as burrs, flash, sintered particles, unevenness, tool marks, and micro-cracks remaining on the inner wall of the tube from the sintering, cutting, and forming processes. It can also precisely repair uneven areas on the inner wall of the pipe, correct minor dimensional deviations and roundness errors in the inner hole, thereby ensuring the overall structural integrity of the tube and the yield rate of finished products.

[0003] However, existing silicon carbide ceramic tube grinding and polishing equipment has insufficient automation and efficiency in processing multiple sets of silicon carbide ceramic tubes in one go, which reduces the processing speed of batches of silicon carbide ceramic tubes. At the same time, after removing burrs and impurities from the tubes, the existing silicon carbide ceramic tube grinding and polishing equipment cannot easily remove various debris and waste inside the tubes in a single processing step. This means that debris may still remain inside the tube, which can easily cause interference between the cutting tool and the debris, affecting the stability of subsequent processing of the tubes. Therefore, a silicon carbide ceramic tube processing equipment is needed to solve the problems mentioned above. Summary of the Invention

[0004] The purpose of this invention is to provide a silicon carbide ceramic tube processing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a silicon carbide ceramic tube processing equipment, comprising a feeding assembly for feeding and unloading, guide rollers rotatably engaged on both sides of the feeding assembly via a support bracket, cam grooves formed outside the guide rollers, a notched turntable fixedly disposed at the power input ends of the two sets of cam grooves, a lever fixedly disposed on the side of the notched turntable, and a synchronous pulley fixedly disposed inside the notched turntable for transmission.

[0006] The transmission component is fixedly installed at the middle of the lower end face of the feeding component, and the transmission component drives the two sets of guide rollers to rotate synchronously through the meshing of the synchronous belt and the synchronous pulley.

[0007] The rotary guide assembly is rotatably engaged inside the feeding assembly, and four sets of silicon carbide tubes are fixedly engaged at equal intervals on the inner end face of the rotary guide assembly. The notched turntable intermittently drives the rotary guide assembly to rotate inside the feeding assembly through the lever.

[0008] The processing components consist of two sets, both of which are slidably mounted on the outside of the guide roller via cam grooves.

[0009] The transmission component drives two sets of notched turntables to rotate in a circular motion via a synchronous pulley and a synchronous belt. The notched turntables drive the rotating material guide assembly to intermittently rotate and guide the silicon carbide tubes via a lever. At the same time, the notched turntables drive the guide rollers to polish, grind and remove chips from the silicon carbide tubes inside the rotating material guide assembly via a cam groove.

[0010] Specifically, the processing assembly includes a support guide seat, an inner polishing assembly that is slidably engaged inside the support guide seat via a linear slide rail, two sets of compressed air bellows fixedly installed via a protective sleeve, and a rack fixedly installed on the support guide seat away from the protective sleeve. The inner polishing assembly is meshed with the rack. One-way valves are fixedly installed at the air intake ends of both sets of compressed air bellows, and the inner polishing assembly is connected to the air intake ends of the two sets of compressed air bellows. The bottom of the inner polishing assembly is connected to a guide slide seat via a sliding shaft with a cam groove.

[0011] Specifically, the internal propulsion assembly includes a linear slide, an air guide pipe rotatably engaged inside the linear slide via two sets of bearing seats, a transmission guide pipe integrally formed and fixedly installed at the power output end of the air guide pipe, and an air guide box fixedly engaged on the side of the linear slide. A cylindrical gear is rotatably engaged on the power input side of the linear slide, and a bevel gear one and a bevel gear two mesh at the output end of the cylindrical gear to drive the air guide pipe to rotate. A limit guide shaft is fixedly installed at the end of the transmission guide pipe, and high-pressure air guide plates are installed at the front and rear of the limit guide shaft. An inner wall cutter is installed outside the limit guide shaft. A one-way valve two is installed at the front and rear of the air guide box, and a sealing sleeve is fixedly installed at the air guide end of the air guide box.

[0012] Specifically, the rotating material guide assembly includes a material guide drum, four sets of positioning grooves equidistantly opened in the center of the inside of the material guide drum, and four sets of supporting guide grooves equidistantly opened in the outer side of the inside of the material guide drum. Inside the material guide drum, four sets of locking pressure plates are equidistantly and elastically slidably engaged by guide components arranged at the front and rear. At the middle of the inner end face of the material guide drum, two sets of pen-shaped cylinders are arranged in front and behind the positioning seat. The output ends of the two sets of pen-shaped cylinders are fixedly equipped with cross pressure plates through docking seats. The two sets of pen-shaped cylinders drive the cross pressure plates to elastically squeeze the locking pressure plates through the docking seats. Buffer guide grooves are opened at both ends of the inner end face of each locking pressure plate.

[0013] Specifically, the guide assembly includes a sealing seat, an alignment support fixedly disposed at the front of the sealing seat, and a grooved wheel fixedly disposed at the rear of the sealing seat. The side of the grooved wheel is provided with four sets of limiting rotating grooves at equal intervals. A guide slide groove is provided between each pair of adjacent sets of limiting rotating grooves. A linear slide shaft is fixedly disposed in the middle of each side of the alignment support, and a return spring is fixedly disposed at the coaxial center of each set of linear slide shafts.

[0014] Specifically, the transmission assembly includes a limiting bracket and a servo motor fixedly mounted at the rear of the limiting bracket via a motor mount. The power output end of the servo motor meshes with bevel gear three and bevel gear four, thereby driving the transmission guide shaft to rotate inside the limiting bracket. Both power output ends of the transmission guide shaft are fixedly connected to synchronous pulley two. The two sets of synchronous pulley two mesh with synchronous belt and synchronous pulley one, thereby driving the two sets of notched turntables to rotate synchronously.

[0015] Specifically, the feeding assembly includes a limiting rotary seat and two sets of guide grooves opened at the front of the limiting rotary seat. A guide slide is fixedly installed at the opening of one of the guide grooves. A pen-shaped cylinder is fixedly installed at the rear of the limiting rotary seat and the guide groove through a cylinder seat. A guide fixture is fixedly installed at the power output end of the pen-shaped cylinder.

[0016] Specifically, the guide roller slides and the cam groove shaft through a cam groove, thereby driving the guide slide and the linear slide to slide back and forth inside the support guide seat. One side of the linear slide is driven by a cylindrical gear meshing with a rack and a bevel gear one meshing with a bevel gear two, thereby driving the transmission guide tube and the inner wall cutter to rotate at high speed. The other side of the linear slide is driven by an air box to compress air into the compressed air bellows in the displacement direction. The compressed air bellows introduces the high-pressure gas into the high-pressure air guide plate through the air box, sealing sleeve, air guide tube and transmission guide tube.

[0017] Both the front and rear of the air guide box are sealed and fixedly connected to the compressed air end of the compressed air bellows via one-way valves. The air delivery end of the air guide box is sealed and rotatedly engaged with the air guide pipe. The sealing sleeve can be sealed and rotatedly engaged with the air guide pipe, allowing the sealing sleeve to guide high-pressure gas into the transmission guide pipe through the air guide pipe. This facilitates the subsequent removal of grinding debris from the grinding area by the high-pressure air guide plate, improving the efficiency of the equipment in grinding the inner wall of the silicon carbide tube and also improving the efficiency of removing debris after grinding the inside of the silicon carbide tube.

[0018] Specifically, two sets of pen-shaped cylinders, arranged in a staggered manner, synchronously drive four sets of locking pressure plates to move outward along the straight direction of the positioning slide groove through the docking seat. The four sets of support guide grooves lock and limit the silicon carbide tube through the locking pressure plates that move outward inside the positioning slide groove. The two sets of pen-shaped cylinders can synchronously push the cross pressure plate to move synchronously through the docking seat, thereby improving the stability and synchronicity of the synchronous pressing and moving of the locking pressure plate by the cross pressure plate, thus improving the stability of the subsequent pressing and locking of the silicon carbide tube.

[0019] Specifically, the power output end of the synchronous pulley one is adapted to rotate and engage with the limiting groove through the notched turntable, and the lever is adapted to slide with the guide groove, thereby driving the grooved wheel and the guide drum to rotate intermittently by 90 degrees. The return spring is fixedly connected to the inner wall of the buffer guide groove, and the alignment support is adapted to the buffer guide groove through the linear sliding shaft, and then elastically engages with the locking plate. When locking and limiting the silicon carbide tube, the combination of the linear sliding shaft and the return spring can provide sufficient linear limiting foundation for the axial guidance of the locking plate, and at the same time provide sufficient elastic force for the subsequent reset of the locking plate, improving the stability of the locking plate reset.

[0020] Specifically, the silicon carbide tube is slidably inserted into the support guide groove via the guide slide and guide groove, and the pen-shaped cylinder 2 drives the silicon carbide tube to move outward along the guide slide via the guide fixture. The guide fixture is made of rubber and includes a push plate and a limiting plate. The limiting plate can be inserted into the silicon carbide tube to improve the stability of the subsequent extraction of the silicon carbide tube.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. This invention is a rotary reciprocating silicon carbide ceramic tube inner wall polishing equipment. When processing silicon carbide tubes in an integrated manner, the servo motor can drive the synchronous pulley and the notched turntable to rotate synchronously through two sets of synchronous pulleys and synchronous belts. This allows the notched turntable to intermittently guide the silicon carbide tube through the rotating material guide assembly via a lever. The notched turntable can also synchronously drive the processing assembly to perform synchronous polishing, deburring, and pneumatic chip removal operations on the guided silicon carbide tube through the guide roller and cam groove. This effectively improves the efficiency and stability of the equipment in processing the inner wall of silicon carbide tubes.

[0023] 2. This invention is a synchronous reciprocating silicon carbide tube processing equipment. During transmission processing, the servo motor can synchronously drive two sets of notched turntables to rotate through two sets of synchronous pulleys, synchronous belts, and synchronous pulleys. This allows the two sets of notched turntables to drive the rotating material guide assembly and the processing assembly through levers and guide rollers, respectively. This enables the processing assembly and the rotating material guide assembly to work synchronously to perform all-round processing operations on the silicon carbide tubes, effectively improving the equipment's power utilization efficiency and also improving the stability and speed of batch processing of silicon carbide tubes.

[0024] 3. This invention is a synchronous polishing and chip removal device. While the air guide box moves back and forth, the inner wall cutter polishes and deburrs the inside of the silicon carbide tube. At the same time, the two sets of compressed air bellows can compress the air guide box and introduce high-pressure gas into the transmission guide tube through the sealing sleeve and air guide tube. This allows the two sets of high-pressure air guide discs to simultaneously remove debris and impurities from the inside out with high-pressure gas while the inner wall cutter polishes and deburrs the inner wall of the silicon carbide tube, thereby improving the efficiency of cleaning the inside of the silicon carbide tube.

[0044] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0045] The invention will be further described below with reference to the accompanying drawings.

[0046] Example 1

[0047] Please see Figures 1-4 One embodiment of the present invention provides a silicon carbide ceramic tube processing device, comprising a feeding assembly 5 for feeding and unloading, guide rollers 12 rotatably engaged on both sides of the feeding assembly 5 via a support bracket 1, cam grooves 11 formed outside the guide rollers 12, a notched turntable 8 fixedly disposed at the power input ends of the two sets of cam grooves 11, a lever 7 fixedly disposed on the side of the notched turntable 8, and a synchronous pulley 9 fixedly disposed inside the notched turntable 8 for transmission.

[0048] The transmission component 4 is fixedly installed at the middle of the lower end face of the feeding component 5, and the transmission component 4 drives the two sets of guide rollers 12 to rotate synchronously through the meshing of the synchronous belt 10 and the synchronous pulley 9.

[0049] The rotating guide assembly 3 is rotatably clamped inside the unloading assembly 5, and four sets of silicon carbide tubes 6 are fixedly clamped at equal intervals on the inner end face of the rotating guide assembly 3. The notched turntable 8 drives the rotating guide assembly 3 to rotate inside the unloading assembly 5 intermittently through the lever 7.

[0050] Processing component 2, there are two sets of processing components 2, and both sets of processing components 2 are slidably sleeved on the outside of guide roller 12 through cam groove 11;

[0051] The transmission component 4 drives two sets of notched turntables 8 to rotate in a circular motion via the synchronous pulley 9 and the synchronous belt 10. The notched turntables 8 drive the rotating material guide component 3 to intermittently rotate and guide the silicon carbide tube 6 via the lever 7. At the same time, the notched turntables 8 drive the guide roller 12 to polish, grind and remove chips from the silicon carbide tube 6 inside the rotating material guide component 3 via the cam groove 11.

[0052] like Figure 5 and Figure 6 The processing component 2 includes a support guide 24, an inner throwing component 22 that is slidably engaged inside the support guide 24 via a linear slide rail 26, two sets of compressed air bellows 21 fixedly installed via a protective sleeve 23, and a rack 25 fixedly installed on the support guide 24 away from the protective sleeve 23. The inner throwing component 22 is meshed with the rack 25. The suction end of each of the two sets of compressed air bellows 21 is fixedly equipped with a one-way valve 29. The one-way valve 29 is model AKH10A-00, which has extremely low opening pressure and can conduct negative pressure and seal positive pressure.

[0053] Furthermore, the inner throwing component 22 is fixedly connected to the compressed air ends of the two sets of compressed air bellows 21, and the bottom of the inner throwing component 22 is connected to the sliding shaft 28 with a cam groove via the guide slide 27.

[0054] like Figure 7 , Figure 8 and Figure 9 The internal propulsion assembly 22 includes a linear slide 228, an air guide pipe 2212 rotatably engaged inside the linear slide 228 via two sets of bearing seats, a transmission conduit 224 integrally formed and fixedly disposed at the power output end of the air guide pipe 2212, and an air guide box 229 fixedly engaged on the side of the linear slide 228. A cylindrical gear 226 is rotatably engaged on the power input side of the linear slide 228, and the output end of the cylindrical gear 226 is connected to a bevel gear 225 via a bevel gear 226. The 27 phases mesh, thereby driving the air guide pipe 2212 to rotate. A limit guide shaft 222 is fixedly installed at the end of the transmission guide pipe 224. High pressure air guide plates 223 are installed at the front and rear of the limit guide shaft 222. An inner wall cutter 221 is installed on the outside of the limit guide shaft 222. A one-way valve 2210 is installed at the front and rear of the air guide box 229. The one-way valve 2210 is of model NRV10, which is open under positive high pressure and sealed under reverse negative pressure.

[0055] A sealing sleeve 2211 is fixedly installed at the air guide end of the air guide box 229.

[0056] The guide roller 12 slides and adapts to the cam groove 28 through the cam groove 11, thereby driving the guide slide 27 and the linear slide 228 to slide back and forth inside the support guide 24. One side of the linear slide 228 meshes with the rack 25 through the cylindrical gear 226 and the bevel gear 225 meshes with the bevel gear 227, thereby driving the transmission guide tube 224 and the inner wall cutter 221 to rotate at high speed. When grinding and deburring the silicon carbide tube 6, the guide roller 12 can drive the linear slide 228 to move back along the inside of the support guide 24 through the sliding limit of the cam groove 11 and the cam groove 28. At the same time, the rack 25 can drive the inner wall cutter 221 to rotate at high speed through the meshing with the cylindrical gear 226 and the transmission of the bevel gear 225 and the bevel gear 227, thereby improving the efficiency and stability of the inner wall cutter 221 in removing burrs inside the silicon carbide tube 6.

[0057] On the other side of the linear slide block 228, the compressed air bellows 21 in the displacement direction is compressed through the air box 229, and the compressed air bellows 21 introduces the high-pressure gas into the high-pressure air guide plate 223 through the air box 229, the sealing sleeve 2211, the air guide pipe 2212 and the transmission guide pipe 224.

[0058] During burr removal, the air box 229 can compress the high-pressure gas generated by the compressed air bellows 21, so that the high-pressure gas can be synchronously introduced into the silicon carbide tube 6 along with the back-and-forth displacement of the transmission duct 224 inside the silicon carbide tube 6, thereby synchronously exporting the grinding debris.

[0059] The front and rear of the air guide box 229 are sealed and fixedly connected to the compressed air end of the compressed air bellows 21 through one-way valve 2210. The air delivery end of the air guide box 229 is sealed and rotatedly engaged with the air guide pipe 2212 through the air guide box 229. The sealing sleeve 2211 can be sealed and rotatedly engaged with the air guide pipe 2212, so that the sealing sleeve 2211 can introduce high pressure gas into the transmission guide pipe 224 through the air guide pipe 2212, which facilitates the subsequent high pressure air guide plate 223 to remove the debris from the grinding area.

[0060] like Figure 10 , Figure 11 and Figure 12 The rotating material guide assembly 3 includes a material guide drum 31, four sets of positioning grooves 37 equidistantly opened in the center of the inside of the material guide drum 31, and four sets of supporting guide grooves 38 equidistantly opened in the outer side of the inside of the material guide drum 31. The inside of the material guide drum 31 is elastically and equidistantly connected to four sets of locking pressure plates 34 by guide components 32 arranged in front and behind. The locking pressure plates 34 are provided with inclined plates on both sides for outward guidance. The cross pressure plate 36 can drive the locking pressure plate 34 to move outward through the inclined plates to squeeze and lock the silicon carbide tube 6.

[0061] Located at the middle of the inner end face of the guide drum 31, two sets of pen-shaped cylinders 310 are set in front and behind the positioning bracket 35. The specific model of the pen-shaped cylinder 310 is: MSBL aluminum alloy mini cylinder.

[0062] The output ends of both sets of pen-shaped cylinders 310 are fixedly equipped with cross pressure plates 36 via docking seats 39. The two sets of pen-shaped cylinders 310 drive the cross pressure plates 36 to elastically compress the locking pressure plates 34 via the docking seats 39. Each locking pressure plate 34 has buffer guide grooves 33 at both ends of its inner end face. The locking pressure plate 34 also has a straight sliding groove inside. The straight sliding groove can slide and limit the pressing end of the cross pressure plate 36, thereby improving the stability of the synchronous pressing and guiding of the locking pressure plate 34 by the cross pressure plate 36, and improving the synchronicity and stability of the outward movement of the four sets of locking pressure plates 34.

[0063] Two sets of pen-shaped cylinders 310, arranged in an alternating pattern, synchronously drive four sets of locking pressure plates 34 to move outward along the straight direction of the positioning slide groove 37 via the docking seat 39. The four sets of supporting guide grooves 38 lock and limit the silicon carbide tube 6 through the outward-moving locking pressure plates 34 within the positioning slide groove 37. Figure 12 Two sets of pen-shaped cylinders 310 are staggered and fixed inside the positioning bracket 35, so that the two sets of pen-shaped cylinders 310 can synchronously push the cross pressure plate 36 to move synchronously through the docking seat 39, thereby improving the stability and synchronicity of the cross pressure plate 36 to the locking pressure plate 34 to move outward synchronously, thereby improving the stability of the subsequent locking pressure plate 34 to squeeze and lock the silicon carbide tube 6.

[0064] like Figure 13 The guide assembly 32 includes a sealing seat 321, an alignment support 327 fixedly disposed at the front of the sealing seat 321, and a grooved wheel 324 fixedly disposed at the rear of the sealing seat 321. The grooved wheel 324 has four sets of limiting grooves 322 equidistantly opened on its side. A guide groove 323 is opened between each pair of adjacent limiting grooves 322. A linear slide shaft 325 is fixedly disposed in the middle of each side of the alignment support 327. A return spring 326 is fixedly disposed at the coaxial center of each set of linear slide shafts 325, which can provide sufficient elastic force for the subsequent reset of the locking pressure plate 34.

[0065] like Figure 2 and Figure 13The power output end of the synchronous pulley 9 is connected to the notched turntable 8 and the limiting groove 322 through rotational engagement, and the lever 7 is connected to the guide groove 323 through sliding engagement, thereby driving the grooved wheel 324 and the guide drum 31 to rotate intermittently by 90 degrees. During intermittent material feeding, the sliding limit of the lever 7 and the guide groove 323 can facilitate the guide drum 31 to drive the silicon carbide tube 6 to rotate. At the same time, the rotational engagement limit of the notched turntable 8 and the limiting groove 322 can provide sufficient guiding components and time for the subsequent inner wall tool 221 to grind and deburr the inside of the silicon carbide tube 6, thereby improving the processing efficiency.

[0066] The return spring 326 is fixedly connected to the inner wall of the buffer guide groove 33, and the alignment support 327 is adapted to the buffer guide groove 33 through the linear slide shaft 325 and then elastically slides and engages with the locking plate 34. When locking and limiting the silicon carbide tube 6, the combination of the linear slide shaft 325 and the return spring 326 can provide sufficient linear limiting basis for the axial guidance of the locking plate 34, and at the same time provide sufficient elastic force for the subsequent reset of the locking plate 34, thereby improving the stability of the reset of the locking plate 34.

[0067] like Figure 14 The transmission component 4 includes a limit card seat 45 and a servo motor 46 fixedly mounted on the rear of the limit card seat 45 via a motor seat. The model of the servo motor 46 is: MHMF082L1U2M.

[0068] The power output end of the servo motor 46 meshes with the bevel gear 42 through the bevel gear 3 41, thereby driving the transmission guide shaft 43 to rotate inside the limit holder 45. Both sides of the transmission guide shaft 43 are rotated and locked inside the limit holder 45 through bearing seats, which can improve the stability of the transmission operation of the transmission guide shaft 43.

[0069] Furthermore, both power output ends of the transmission guide shaft 43 are fixedly connected to synchronous pulleys 44. The two sets of synchronous pulleys 44 mesh with synchronous belt 10 and synchronous pulley 9, thereby driving the two sets of notched turntables 8 to rotate synchronously. The meshing transmission of synchronous pulleys 44 and synchronous pulley 9 with synchronous belt 10 can improve both the stability and the synchronicity of the transmission.

[0070] like Figure 15 and Figure 16 The feeding assembly 5 includes a limiting rotary seat 54 and two sets of guide grooves 55 opened at the front of the limiting rotary seat 54. A guide slide plate 56 is fixedly installed at the opening of one of the guide grooves 55. A pen-shaped cylinder 52 is fixedly installed at the rear of the limiting rotary seat 54 and the guide groove 55 through a cylinder seat 51. The specific model of the pen-shaped cylinder 52 is: MSBL-SUFA aluminum alloy mini cylinder.

[0071] Furthermore, a guide fixture 53 is fixedly installed at the power output end of the pen-shaped cylinder 52. The guide fixture 53 can not only protect the outside of the silicon carbide tube 6, but also improve the stability and efficiency of feeding the silicon carbide tube 6.

[0072] like Figure 3 and Figure 15 When feeding silicon carbide tube 6, the external feeding robot arm can guide silicon carbide tube 6 into the inside of the guide slide plate 56, and then slide and insert silicon carbide tube 6 into the support guide groove 38 through the guide slide plate 56 and the guide groove 55, which can improve the stability and accuracy of feeding guidance.

[0073] Furthermore, the pen-shaped cylinder 52 drives the silicon carbide tube 6 to move outward along the guide slide plate 56 via the guide fixture 53. The guide fixture 53 is made of rubber and includes a push plate and a limiting plate. The limiting plate can be inserted into the inside of the silicon carbide tube 6, thereby improving the stability of the subsequent extraction of the silicon carbide tube 6.

[0074] Working principle: such as Figure 1 and Figure 16 Before processing the silicon carbide tube 6, the operator can position the loading / unloading robotic arm at the rear of the guide slide plate 56 to facilitate continuous loading or unloading of the silicon carbide tube 6. During loading, the external robotic arm can push the silicon carbide tube 6 into the support guide groove 38 through the guide slide plate 56. Figure 16 The guide fixture 53 on the opposite side of the support guide groove 38 can limit the silicon carbide tube 6, so that the silicon carbide tube 6 can be completely positioned inside the support guide groove 38. After the four sets of silicon carbide tubes 6 are fed, as Figure 11 and Figure 12 When the silicon carbide tube 6 is locked, the external touch screen module can activate the solenoid valves corresponding to the two sets of pen-shaped cylinders 310 via an electrical signal. This allows the two sets of pen-shaped cylinders 310 to synchronously drive the cross pressure plate 36 to move outward through the docking seat 39. Consequently, the two sets of cross pressure plates 36 can synchronously drive the four sets of locking pressure plates 34 along the path shown in the image. Figure 13 The linear slide shaft 325 moves outward in the axial direction, so that the locking pressure plate 34, along the elastic guide of the linear slide shaft 325, eventually locks and limits the four sets of silicon carbide tubes 6 inside the support guide groove 38 through the positioning slide groove 37. The silicon carbide tubes 6 will be deflected during the subsequent polishing and deburring of the inside of the textile.

[0075] like Figure 4 and Figure 14When grinding and deburring the inner wall of the silicon carbide tube 6, the operator can start the servo motor 46 via the PLC in the external touchscreen module. The servo motor 46 then drives the front bevel gear 3 41 to rotate. Simultaneously, the bevel gear 3 41, through the bevel gear 42 and the transmission guide shaft 43, drives the synchronous pulleys 2 44 at both ends to rotate. The synchronous pulleys 2 44, through the synchronous belt 10, simultaneously drive the synchronous pulley 9 to rotate, causing the synchronous pulley 9 to synchronously drive the notched turntable 8 to rotate. The notched turntable 8 can then be moved separately via the lever 7 and the guide roller 12.

[0076] like Figure 2 and Figure 4 During intermittent material feeding, the notched turntable 8 can drive the lever 7 to rotate circumferentially. At this time, the lever 7 can slide and limit the guide groove 323, thereby driving the grooved wheel 324, the guide drum 31, the support guide groove 38 and the silicon carbide tube 6 to rotate 90 degrees to feed the material. When the lever 7 separates from the guide groove 323, the notched turntable 8 can engage with the limiting groove 322 to limit the grooved wheel 324, the guide drum 31, the support guide groove 38 and the silicon carbide tube 6, thus providing sufficient limiting basis for the subsequent grinding of the silicon carbide tube 6.

[0077] like Figure 2 , Figure 5 and Figure 8During the cyclic grinding and deburring operation of the inner wall of the silicon carbide tube 6, the notched turntable 8, while synchronously driving the guide drum 31 to intermittently rotate and guide the material via the lever 7, can also synchronously drive the guide roller 12 to rotate. This allows the guide roller 12 to be limited by the sliding of the cam groove 11 and the cam groove shaft 28, thereby cyclically driving the guide slide 27 and the cam groove shaft 28 to move back and forth inside the support guide seat 24. At the same time, when the linear slide 228 moves back and forth along the linear slide rail 26, the rack 25 can synchronously drive the bevel gear 225 to rotate by meshing with the cylindrical gear 226. This allows the bevel gear 225 to synchronously drive the air guide pipe 2212 to rotate at high speed by meshing with the bevel gear 227. This allows the air guide pipe 2212 to synchronously drive the limiting guide shaft 222 and the inner wall cutter 221 to rotate at high speed through the transmission guide pipe 224. When the notched turntable 221... When the turntable 8 rotates the grooved wheel 324 90 degrees via the lever 7 to guide the material, the guide roller 12 can be limited by the sliding of the cam groove 11 and the cam groove shaft 28, thereby driving the linear slide 228 to move backward. At this time, the inner wall cutter 221 is not disengaged from the silicon carbide tube 6 to avoid interference. At the same time, when the notched turntable 8 is locked with the limiting groove 322, the guide roller 12 drives the high-speed rotating inner wall cutter 221 through the cam groove 11 to be guided into the interior of the silicon carbide tube 6. The two sets of opposing linear slides 228 can be synchronously rotated at high speed inside the silicon carbide tube 6 by the two sets of inner wall cutters 221, thereby performing all-round polishing and deburring operations on various burrs and impurities inside the silicon carbide tube 6. Then the above operation is repeated. When the notched turntable 8 drives the guide drum 31 to guide the material again via the lever 7, the inner wall cutter 221 returns to the position where it is separated from the silicon carbide tube 6 again.

[0078] like Figure 6 , Figure 7 , Figure 8 and Figure 9When the linear slide 228 moves toward the silicon carbide tube 6, the air guide box 229 compresses the compressed air bellows 21 in the direction of displacement. At this time, the high-pressure one-way valve at the tail end of the compressed air bellows 21 is closed, and the one-way valve 2210 is opened. The high-pressure air compressed by the compressed air bellows 21 can be transported to the inside of the air guide pipe 2212 through the air guide box 229 and the sealing sleeve 2211, so that the air guide pipe 2212 can transport the high-pressure air to the transmission guide pipe 224. In the aforementioned transmission conduit 224, when the inner wall tool 221 polishes the burrs and debris on the inner wall of the silicon carbide tube 6, the two sets of high-pressure air guide plates 223 can use high-pressure gas to discharge the debris and debris inside the silicon carbide tube 6 from the inside out, and simultaneously complete the chip removal operation to prevent subsequent burrs and debris from affecting the repeated cutting of the inner wall tool 221. At the same time, the one-way valve 2210 of the compressed air bellows 21 located in the extension part is closed, and the one-way valve 29 is opened to complete the air replenishment operation.

[0079] like Figure 3 and Figure 16 When the silicon carbide tube 6 is polished and deburred after multiple cycles of processing, the external touch screen module can start the pen-shaped cylinder 52 through the solenoid valve. At this time, the pen-shaped cylinder 52 can drive the silicon carbide tube 6 inside the support guide groove 38 to be discharged onto the guide slide plate 56 through the guide fixture 53, thus completing the discharge.
