Description

Technical Field

[0001] This invention relates to the field of carbon fiber tube technology, specifically to a grinding device for variable diameter carbon fiber tubes. Background Technology

[0002] Carbon fiber tubes, also known as carbon fiber tubes or carbon tubes, are made by pre-impregnating carbon fiber composite materials with styrene-based polyester resin and then heating and curing them through pultrusion (winding). During the manufacturing process, various profiles can be produced using different molds, such as carbon fiber round tubes of different specifications, square tubes of different specifications, sheets of different specifications, and other profiles. When processing carbon fiber tubes, they need to be polished to facilitate subsequent processing operations.

[0003] Existing carbon fiber tube polishing equipment typically sprays water directly onto the tube wall during the water spraying operation to assist in polishing when polishing variable diameter carbon fiber tubes. However, when polishing smaller diameter carbon fiber tubes, direct water spraying causes water to accumulate on the outer wall of the tube, forming a water film that affects the polishing process and results in insufficient polishing quality. Summary of the Invention

[0004] The purpose of this invention is to provide a variable diameter carbon fiber tube polishing device. The device moves a movable tube to drive the second water outlet to move. The position of the second water outlet is adjusted according to the diameter of the carbon fiber tube, and water is sprayed at different positions. This avoids the formation of a water film on the carbon fiber tube when the diameter is short, which would affect the polishing quality of the carbon fiber tube. Thus, the position of the sprayed water is adjusted according to the diameter of the carbon fiber tube, thereby improving the polishing quality of the carbon fiber tube.

Compared with the prior art, the beneficial effects of the present invention are: This invention moves the second water outlet by moving the moving tube. The position of the second water outlet is adjusted by the diameter of the carbon fiber tube, and water is sprayed at different positions. This avoids the formation of a water film on the carbon fiber tube when the diameter is short, which would affect the polishing quality of the carbon fiber tube. Thus, the position of the sprayed water is adjusted according to the diameter of the carbon fiber tube, thereby improving the polishing quality of the carbon fiber tube.

[0015] This invention uses two sets of cleaning hands on one side of the grinding disc to squeeze the falling clean non-woven fabric. Combined with the rotation of the carbon fiber tube, this removes moisture and impurities adhering to the carbon fiber tube, preventing residual moisture and impurities from affecting the grinding quality of the carbon fiber tube. At the same time, during each grinding, the one-way gear drives the feeding roller to move a certain distance, ensuring that the non-woven fabric that comes into contact with the carbon fiber tube is always clean. This avoids the use of non-woven fabric with residual impurities that could scratch the outer wall of the carbon fiber tube and affect its quality.

[0016] This invention uses the scale on the scale plate to determine whether the grinding of the carbon fiber tube meets the estimated quality. When the scales on the two sides of the measuring plate are inconsistent, the carbon fiber tube can be ground again. When the scale of the measuring plate reaches the estimated scale, it can be manually adjusted to end the grinding in advance to avoid over-grinding. Attached Figure Description

Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] This invention provides a grinding device for variable diameter carbon fiber tubes, including a worktable 1, with an auxiliary mechanism 2 provided at one end of the worktable 1; The auxiliary mechanism 2 includes a movable table 22 that slides inside the workbench 1. A second reciprocating screw 24 passes through one side of the movable table 22. A movable plate 25 slides on the movable table 22. A grinding disc 28 is provided on one side of the movable plate 25. A movable rod 210 is provided at the upper end of the grinding disc 28. A movable tube 214 is provided inside the movable rod 210. One end of the movable tube 214 is connected to a connecting box 216. A second water outlet 218 is provided at the lower end of the movable tube 214. A transfer box 220 is provided at the lower end of the connecting box 216. A telescopic tube 211 is provided at the lower end of the transfer box 220. A cleaning mechanism 3 is also provided at the upper end of the movable table 22. The cleaning mechanism 3 includes an auxiliary plate 31 that slides on the moving table 22. A rack 32 is provided at the upper end of the auxiliary plate 31. Fixed plates 33 are provided on both sides of the auxiliary plate 31. A one-way gear 34 rotates inside the fixed plate 33. Feeding rollers 35 are provided through the fixed plate 33 at both ends of the one-way gear 34. Two sets of cleaning hands 36 are provided on one side of the grinding disc 28. A detection mechanism 4 is also provided at the upper end of the moving rod 210. The testing mechanism 4 includes a push plate 42 fixed to the upper end of the moving rod 210. The workbench 1 has two sets of scale plates 41 inside, and multiple sets of limiting columns 43 are set inside the scale plates 41. Multiple sets of measuring plates 44 pass through the limiting columns 43.

[0021] Before using this device, the variable-diameter carbon fiber tube to be ground is clamped by the clamping components on both sides of the worktable 1. After clamping, the first reciprocating screw 21 drives the moving table 22 to move to one end of the carbon fiber tube. After moving to one end of the carbon fiber tube, the motor 23 drives the second reciprocating screw 24 to rotate. The rotation of the second reciprocating screw 24 drives the moving plate 25 to move on the limiting rod 29. The movement of the moving plate 25 drives the protective shell 26 to move. The movement of the protective shell 26 drives the protective sleeve 27 to move. The movement of the protective sleeve 27 drives... The grinding disc 28 moves, squeezing the inner carbon fiber tube. The second reciprocating screw 24 rotates a certain distance and then stops, causing the grinding disc 28 to compress the outer wall of the carbon fiber tube. At the same time, the grinding disc 28 compresses the spring 224, thereby driving the moving rod 210 to move. The moving rod 210 drives the moving tube 214 to move inside the limiting sleeve 215. The moving tube 214 drives the second water outlet 218 to move. After grinding begins, water in the storage tank enters the hose 217 through the connecting box 216. The water is then sprayed out from the second outlet 218. When the diameter of the carbon fiber tube contacted by the grinding disc 28 is large, the distance that the grinding disc 28 drives the moving rod 210 to move is small, resulting in a shorter distance that the moving tube 214 moves. Water is then sprayed from the second outlet 218 onto the carbon fiber tube for auxiliary grinding, reducing dust splashing during grinding and improving grinding quality. When the diameter of the carbon fiber tube contacted by the grinding disc 28 is large, the distance that the moving rod 210 drives the moving tube 214 to move is longer, resulting in a longer distance that the water in the second outlet 218... The water is sprayed into the transfer box 220, allowing it to enter the delivery pipe 221 through the moving rod 210, and then through the telescopic pipe 211 into the first water outlet 212 at both ends before being sprayed into the coating disc 223. By wetting the coating disc 223, some of the water is applied to the carbon fiber tube, preventing the water from forming a water film on the carbon fiber tube when the diameter of the carbon fiber tube is short, which would affect the polishing quality of the carbon fiber tube. Thus, the position of the sprayed water can be adjusted according to the diameter of the carbon fiber tube to improve the polishing quality of the carbon fiber tube.

[0022] Simultaneously, during operation, the device rotates via the first reciprocating screw 21 to move the moving table 22, and then rotates via the second reciprocating screw 24 to move the grinding disc 28 to grind the carbon fiber tube. After grinding a section of the carbon fiber tube, the motor 23 drives the second reciprocating screw 24 to reverse, causing the grinding disc 28 to reset. The motor 23 then rotates to move the moving table 22 to grind the next section of the carbon fiber tube, thus grinding the entire carbon fiber tube. Simultaneously, when the second reciprocating screw 24 rotates to move the moving plate 25, the moving plate 25 causes the rack 32 to slide on the auxiliary plate 31. The rack 32's movement causes the one-way gear 34 to rotate, and the one-way gear 34's rotation... The feed rollers 35 on both sides rotate, causing the non-woven fabric roll placed on the feed rollers 35 to rotate, resulting in a certain amount of non-woven fabric falling down. When the non-woven fabric is polished by the polishing disc 28, the two sets of cleaning hands 36 on one side of the polishing disc 28 squeeze the falling clean non-woven fabric. In conjunction with the rotation of the carbon fiber tube, the moisture and impurities attached to the carbon fiber tube are cleaned, preventing moisture and impurities from affecting the polishing quality of the carbon fiber tube. At the same time, each time the polishing is performed, the one-way gear 34 drives the feed roller 35 to move a certain distance, so that the non-woven fabric that comes into contact with the carbon fiber tube is clean each time. This avoids the use of non-woven fabric with impurities that could scratch the outer wall of the carbon fiber tube and affect its quality.

[0023] Simultaneously, when the grinding disc 28 grinds the carbon fiber tube, it drives the moving rod 210 to move. The moving rod 210 drives the pushing plate 42 to move. The moving pushing plate 42 pushes the measuring plate 44, causing the measuring plate 44 to slide on the limiting post 43. Each time grinding is performed, the measuring plate 44 is pushed. The scale on the scale plate 41 can be used to observe whether the grinding of the carbon fiber tube on both sides is uniform. At the same time, the scale on the scale plate 41 can be used to determine whether the grinding of the carbon fiber tube meets the estimated quality. When the scales on the measuring plates 44 on both sides are inconsistent, the carbon fiber tube can be ground again. When the scale of the measuring plate 44 reaches the estimated scale, it can be manually adjusted to end the grinding in advance to avoid over-grinding.

[0024] In an optional embodiment, the worktable 1 is provided with two sets of first reciprocating lead screws 21, the moving stage 22 slides on the first reciprocating lead screws 21, and the worktable 1 is provided with a first groove whose size is adapted to the moving stage 22.

[0025] It should be noted that the first reciprocating screw 21 rotates to drive the moving table 22 to move. At the same time, the moving table 22 moves in the groove inside the worktable 1 to prevent the moving table 22 from deviating from the predetermined track and affecting the grinding quality of the device.

[0026] In an optional embodiment, a motor 23 is fixedly installed on one side of the moving stage 22. The output end of the motor 23 is connected to the second reciprocating lead screw 24, which passes through the moving plate 25. A limiting plate 213 is provided at one end of the moving plate 25.

[0027] It should be noted that the second reciprocating screw 24 is rotated by the motor 23, and the rotation of the second reciprocating screw 24 drives the moving plate 25 to move. After the moving plate 25 moves to a certain distance, the grinding disc 28 contacts and squeezes the carbon fiber tube, thereby grinding the carbon fiber tube.

[0028] In an optional embodiment, a protective shell 26 is provided at the bottom of the movable plate 25, and a protective sleeve 27 is provided inside the protective shell 26. One end of the protective sleeve 27 is connected to the grinding disc 28, and a spring 224 is provided inside the protective sleeve 27. One end of the grinding disc 28 is connected to the spring 224.

[0029] It should be noted that the movement of the movable plate 25 causes the protective shell 26 to move, the movement of the protective shell 26 causes the protective sleeve 27 to move, and the movement of the protective sleeve 27 causes the spring 224 to press against the grinding disc 28, thereby causing the grinding disc 28 to move.

[0030] In an optional embodiment, a limiting rod 29 is provided on one side of the moving platform 22, with one end of the limiting rod 29 penetrating through the moving plate 25.

[0031] It should be noted that the rotation of the second reciprocating screw 24 drives the moving plate 25 to move on the limiting rod 29, thereby restricting the moving plate 25 and preventing it from deviating from the predetermined track during movement, which would affect the grinding of the device.

[0032] In an optional embodiment, a limiting sleeve 215 is provided at one end of the moving tube 214, and one end of the limiting sleeve 215 is fixedly connected to the connecting box 216. Flexible tubes 217 are provided at both ends of the connecting box 216, and one end of the flexible tube 217 is connected to the moving tube 214.

[0033] It should be noted that the movement of the moving rod 210 causes the moving pipe 214 to move. The moving pipe 214 moves inside the limiting sleeve 215, while water enters the moving pipe 214 from the connecting box 216 through the hose 217.

[0034] In an optional embodiment, a connecting rod 219 is provided at the lower end of the connecting box 216. The lower end of the connecting rod 219 is connected to the transfer box 220. The lower end of the transfer box 220 is connected to the conveying pipe 221. Both sides of the conveying pipe 221 are connected to the telescopic pipe 211. Both ends of the telescopic pipe 211 are provided with a first water outlet 212. One end of the telescopic pipe 211 is connected to the moving rod 210.

[0035] It should be noted that the movement of the moving pipe 214 causes the second water outlet 218 to move, spraying water from the second water outlet 218 into the transfer box 220, then through the conveying pipe 221 into the telescopic pipe 211, and then through the telescopic pipe 211 into the first water outlet 212, where it is sprayed onto the coating plate 223 for coating.

[0036] In an optional embodiment, telescopic plates 222 are provided on both sides of the movable rod 210, and an applicator 223 is provided on the inner side of the telescopic plates 222.

[0037] It should be noted that when the diameter of the carbon fiber tube is small, the moving rod 210 drives the moving tube 214 to move, and the moving tube 214 drives the second water outlet 218 to move, spraying water through the first water outlet 212 onto the surface of the coating plate 223. The coating plate 223 is used to coat the outer wall of the carbon fiber tube, avoiding the formation of a water film on the tube wall directly, which would affect the polishing of the carbon fiber tube. At the same time, the telescopic plate 222 is telescopic, which facilitates the coating of the carbon fiber tube.

[0038] In an optional embodiment, the auxiliary plate 31 is provided with a limiting strip 37, and the rack 32 is provided with a second groove whose size is adapted to the limiting strip 37.

[0039] It should be noted that the rack 32 slides on the limiting strip 37 to prevent the rack 32 from derailing from the track when it moves, thus avoiding any impact on the normal operation of the device.

[0040] In an optional embodiment, a water storage tank is provided on one side of the workbench 1, one end of the water storage tank is connected to the protective shell 26, and clamping components are provided at both ends of the workbench 1.

[0041] It should be noted that water is transported to the connecting box 216 through the water storage tank for spraying, while the clamping component drives the carbon fiber tube to rotate, which facilitates grinding.

[0042] Working principle: Before using this device, the variable diameter carbon fiber tube to be ground is clamped by the clamping components on both sides of the worktable 1. After clamping, the first reciprocating screw 21 drives the moving table 22 to move to one end of the carbon fiber tube. After moving to one end of the carbon fiber tube, the motor 23 drives the second reciprocating screw 24 to rotate. The rotation of the second reciprocating screw 24 drives the moving plate 25 to move on the limiting rod 29. The movement of the moving plate 25 drives the protective shell 26 to move. The movement of the protective shell 26 drives the protective sleeve 27 to move. The movement of the protective sleeve 27 drives the grinding process. The grinding disc 28 moves, squeezing the inner carbon fiber tube. The second reciprocating screw 24 rotates a certain distance and then stops, causing the grinding disc 28 to squeeze the outer wall of the carbon fiber tube. At the same time, the grinding disc 28 squeezes the spring 224, thereby driving the moving rod 210 to move. The moving rod 210 moves inside the limiting plate 213, which in turn drives the moving tube 214 to move inside the limiting sleeve 215. The moving tube 214 then drives the second water outlet 218 to move. After grinding begins, water in the storage tank flows through the connection... Water enters the hose 217 from the container 216 and then sprays out from the second outlet 218. When the diameter of the carbon fiber tube contacted by the grinding disc 28 is large, the distance that the grinding disc 28 moves with the moving rod 210 is smaller, resulting in a shorter distance that the moving tube 214 moves. Water is sprayed from the second outlet 218 onto the carbon fiber tube for auxiliary grinding, reducing dust splashing during grinding and improving grinding quality. When the diameter of the carbon fiber tube contacted by the grinding disc 28 is large, the distance that the moving rod 210 moves with the moving tube 214 is longer, resulting in a shorter distance that the second outlet... Water from 218 is sprayed into the transfer box 220, allowing water to enter the conveying pipe 221 through the moving rod 210, and then enter the first water outlet 212 at both ends through the telescopic pipe 211 before being sprayed into the coating disc 223. By wetting the coating disc 223, some water is applied to the carbon fiber tube, preventing the water from forming a water film on the carbon fiber tube when the diameter of the carbon fiber tube is short, which would affect the polishing quality of the carbon fiber tube. Thus, the position of the sprayed water is adjusted according to the diameter of the carbon fiber tube, thereby improving the polishing quality of the carbon fiber tube.

[0043] Simultaneously, during operation, the device rotates via the first reciprocating screw 21 to move the moving table 22, and then rotates via the second reciprocating screw 24 to move the grinding disc 28 to grind the carbon fiber tube. After grinding a section of the carbon fiber tube, the motor 23 drives the second reciprocating screw 24 to reverse, causing the grinding disc 28 to reset. The motor 23 then rotates to move the moving table 22 to grind the next section of the carbon fiber tube, thus grinding the entire carbon fiber tube. Simultaneously, when the second reciprocating screw 24 rotates to move the moving plate 25, the moving plate 25 causes the rack 32 to slide on the auxiliary plate 31. The rack 32's movement causes the one-way gear 34 to rotate, and the one-way gear 34's rotation... The feed rollers 35 on both sides rotate, causing the non-woven fabric roll placed on the feed rollers 35 to rotate, resulting in a certain amount of non-woven fabric falling down. When the non-woven fabric is polished by the polishing disc 28, the two sets of cleaning hands 36 on one side of the polishing disc 28 squeeze the falling clean non-woven fabric. In conjunction with the rotation of the carbon fiber tube, the moisture and impurities attached to the carbon fiber tube are cleaned, preventing moisture and impurities from affecting the polishing quality of the carbon fiber tube. At the same time, each time the polishing is performed, the one-way gear 34 drives the feed roller 35 to move a certain distance, so that the non-woven fabric that comes into contact with the carbon fiber tube is clean each time. This avoids the use of non-woven fabric with impurities that could scratch the outer wall of the carbon fiber tube and affect its quality.

[0044] Simultaneously, when the grinding disc 28 grinds the carbon fiber tube, it drives the moving rod 210 to move. The moving rod 210 drives the pushing plate 42 to move. The moving pushing plate 42 pushes the measuring plate 44, causing the measuring plate 44 to slide on the limiting post 43. Each time grinding is performed, the measuring plate 44 is pushed. The scale on the scale plate 41 can be used to observe whether the grinding of the carbon fiber tube on both sides is uniform. At the same time, the scale on the scale plate 41 can be used to determine whether the grinding of the carbon fiber tube meets the estimated quality. When the scales on the measuring plates 44 on both sides are inconsistent, the carbon fiber tube can be ground again. When the scale of the measuring plate 44 reaches the estimated scale, it can be manually adjusted to end the grinding in advance to avoid over-grinding.

[0045] The second reciprocating screw 24 rotates, driving the moving plate 25 to move on the limiting rod 29, thus restricting the moving plate 25 and preventing it from deviating from the predetermined track, which would affect the grinding of the device. The rack 32 slides on the limiting strip 37 to prevent it from deviating from the track and affecting the normal operation of the device. Water is transported to the connecting box 216 through the water storage tank for spraying. At the same time, the clamping component drives the carbon fiber tube to rotate, which facilitates grinding.
