[0001] The present invention relates to the technical field of carbon fiber tubes, and particularly to a grinding device for variable-diameter carbon fiber tubes. Background Art

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

[0003] In the existing carbon fiber tube grinding device, when grinding variable-diameter carbon fiber tubes, during the water spraying operation, water is usually directly sprayed on the carbon fiber tube wall for auxiliary grinding.

DETAILED DESCRIPTION OF THE INVENTION

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0020] The present invention provides a variable-diameter carbon fiber tube grinding device, including a workbench 1, and an auxiliary mechanism 2 is arranged at one end of the workbench 1; The auxiliary mechanism 2 includes a moving table 22 that slides inside the workbench 1. A second reciprocating lead screw 24 penetrates through one side of the moving table 22. A moving plate 25 slides on the moving table 22. A grinding piece 28 is arranged on one side of the moving plate 25. A moving rod 210 is arranged at the upper end of the grinding piece 28. A moving tube 214 is arranged inside the moving rod 210. One end of the moving tube 214 is connected to a communication box 216. A second water outlet 218 is arranged at the lower end of the moving tube 214. A transfer box 220 is arranged at the lower end of the communication box 216. A telescopic tube 211 is arranged at the lower end of the transfer box 220. A cleaning mechanism 3 is also arranged at the upper end of the moving table 22; The cleaning mechanism 3 includes an auxiliary plate 31 that slides on the moving table 22. A rack 32 is arranged at the upper end of the auxiliary plate 31. Fixing plates 33 are arranged on both sides of the auxiliary plate 31. A one-way gear 34 rotates inside the fixing plates 33. Feeding rollers 35 penetrate through both ends of the one-way gear 34 and are arranged on the fixing plates 33. Two groups of cleaning hands 36 are arranged on one side of the grinding piece 28. A detection mechanism 4 is also arranged at the upper end of the moving rod 210; The detection mechanism 4 includes a pushing plate 42 fixed at the upper end of the moving rod 210. Two groups of scale plates 41 are arranged inside the workbench 1. Multiple groups of limiting columns 43 are arranged inside the scale plates 41. Multiple groups of measuring plates 44 penetrate through the limiting columns 43.

[0021] Before using this device, the variable-diameter carbon fiber tube to be polished is clamped by the clamping components on both sides of the workbench 1. After clamping, the moving table 22 is driven to move to one end of the carbon fiber tube by the rotation of the first reciprocating screw rod 21. After moving to one end of the carbon fiber tube, the second reciprocating screw rod 24 is driven to rotate by the motor 23. The rotation of the second reciprocating screw rod 24 drives the moving plate 25 to move on the limiting rod 29. The movement of the moving plate 25 drives the movement of the protective shell 26. The movement of the protective shell 26 drives the movement of the protective sleeve 27. The movement of the protective sleeve 27 drives the movement of the grinding disc 28. The movement of the grinding disc 28 squeezes the inner carbon fiber tube. After the second reciprocating screw rod 24 rotates a certain distance and stops, a certain extrusion is generated between the grinding disc 28 and the outer wall of the carbon fiber tube. At the same time, the grinding disc 28 squeezes the spring 224, thereby driving the movement of the moving rod 210. The movement of the moving rod 210 drives the movement of the moving tube 214 inside the limiting sleeve 215. The movement of the moving tube 214 drives the movement of the second water outlet 218. After starting the grinding, the water in the water storage tank enters the hose 217 through the communication box 216 and then sprays out from the second water outlet 218. When the diameter of the carbon fiber tube in contact with the grinding disc 28 is larger, the distance that the grinding disc 28 drives the moving rod 210 to move is smaller, so that the moving distance of the moving tube 214 is shorter. The water sprays out from the second water outlet 218 onto the carbon fiber tube for auxiliary grinding, reducing the splashing of dust during grinding and improving the grinding quality. When the diameter of the carbon fiber tube in contact with the grinding disc 28 is larger, the distance that the moving rod 210 drives the moving tube 214 to move is longer, so that the water in the second water outlet 218 sprays into the transfer box 220. The water enters the conveying pipe 221 from the moving rod 210 and sprays out from the first water outlets 212 at both ends through the telescopic pipe 211 and into the coating disc 223. By wetting the coating disc 223, the coating disc 223 wets and smears part of the water onto the carbon fiber tube, avoiding the formation of a water film on the carbon fiber tube when the water sprays out when the diameter of the carbon fiber tube is shorter, which affects the grinding quality of the carbon fiber tube. Thus, according to the diameter of the carbon fiber tube, the position of the sprayed water is adjusted to improve the grinding quality of the carbon fiber tube.

[0022] When the device is in use, the first reciprocating screw rod 21 rotates to drive the moving table 22 to move, and then the second reciprocating screw rod 24 rotates to drive the grinding disc 28 to move to grind the carbon fiber tube. After grinding a section of the carbon fiber tube, the motor 23 drives the second reciprocating screw rod 24 to reverse to reset the grinding disc 28, and then the motor 23 rotates to drive the moving table 22 to move to grind the next section of the carbon fiber tube, so as to carry out the work of grinding the entire carbon fiber tube. At the same time, when the second reciprocating screw rod 24 rotates to drive the moving plate 25 to move, the moving plate 25 moves to drive the rack 32 to slide on the auxiliary plate 31. The movement of the rack 32 drives the one-way gear 34 to rotate, and the rotation of the one-way gear 34 drives the feeding rollers 35 on both sides to rotate, rotating the non-woven fabric roll placed on the feeding rollers 35, so that a certain amount of non-woven fabric drops from the non-woven fabric roll. When grinding by the grinding disc 28, two groups of cleaning hands 36 on one side of the grinding disc 28 squeeze the dropped clean non-woven fabric, and cooperate with the rotation of the carbon fiber tube to clean the moisture and impurities attached to the carbon fiber tube, avoiding the influence of the residual moisture and impurities on the grinding quality of the carbon fiber tube. At the same time, each time when grinding, the one-way gear 34 drives the feeding roller 35 to move a certain distance, so that each time the non-woven fabric in contact with the carbon fiber tube is clean, avoiding scratches on the outer wall of the carbon fiber tube caused by impurities remaining on the used non-woven fabric and affecting the quality of the carbon fiber tube.

[0023] At the same time, when the grinding disc 28 grinds the carbon fiber tube, it drives the moving rod 210 to move. The movement of the moving rod 210 drives the pushing plate 42 to move. The movement of the pushing plate 42 pushes the measuring plate 44, so that the measuring plate 44 slides on the limiting column 43. Each time when grinding, the measuring plate 44 will be pushed. Through the scales on the scale plate 41, it can be observed whether the grinding of the carbon fiber tubes on both sides is uniform. At the same time, through the scales on the scale plate 41, it can be judged whether the grinding of the carbon fiber tube meets the expected quality. When the scales of 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 expected scale, it can be manually adjusted to end the grinding in advance to avoid over-grinding.

[0024] In an optional embodiment, two groups of first reciprocating screw rods 21 are arranged on the workbench 1, and the moving table 22 slides on the first reciprocating screw rods 21. A first groove is arranged inside the workbench 1, and its size is adapted to the moving table 22.

[0025] It should be noted that the first reciprocating screw rod 21 rotates to drive the moving table 22 to move, and at the same time, the moving table 22 moves in the groove inside the workbench 1, avoiding the moving table 22 moving out of the predetermined track and affecting the grinding quality of the device.

[0026] In an alternative embodiment, a motor 23 is fixedly arranged on one side of the mobile station 22. The output end of the motor 23 is connected to a second reciprocating lead screw 24. The second reciprocating lead screw 24 passes through the moving plate 25, and a limiting plate 213 is arranged at one end of the moving plate 25.

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

[0028] In an alternative embodiment, a protective shell 26 is arranged at the bottom of the moving plate 25. A protective sleeve 27 is arranged inside the protective shell 26. One end of the protective sleeve 27 is connected to the grinding disc 28. A spring 224 is arranged 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 moving plate 25 drives the movement of the protective shell 26. The movement of the protective shell 26 drives the movement of the protective sleeve 27. The movement of the protective sleeve 27 drives the spring 224 to press the grinding disc 28, thereby driving the movement of the grinding disc 28.

[0030] In an alternative embodiment, a limiting rod 29 is arranged on one side of the mobile station 22. One end of the limiting rod 29 passes through the moving plate 25.

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

[0032] In an alternative embodiment, a limiting sleeve 215 is arranged at one end of the moving tube 214. One end of the limiting sleeve 215 is fixedly connected to the communication box 216. Hoses 217 are arranged at both ends of the communication box 216. One end of each hose 217 is communicated with the moving tube 214.

[0033] It should be noted that the movement of the moving rod 210 drives the movement of the moving tube 214. The moving tube 214 moves inside the limiting sleeve 215. At the same time, water enters the moving tube 214 from the communication box 216 through the hoses 217.

[0034] In an alternative embodiment, a connecting rod 219 is arranged at the lower end of the communication 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 communicated with a delivery pipe 221. Both sides of the delivery pipe 221 are communicated with telescopic pipes 211. First water outlets 212 are arranged at both ends of each telescopic pipe 211. One end of each telescopic pipe 211 is connected to the moving rod 210.

[0035] It should be noted that the movement of the movable pipe 214 drives the movement of the second water outlet 218, and water is ejected from the second water outlet 218 into the transfer tank 220, enters the telescopic pipe 211 through the delivery pipe 221, enters the first water outlet 212 through the telescopic pipe 211, and is ejected onto the coating disc 223 for coating.

[0036] In an alternative embodiment, telescopic plates 222 are arranged on both sides of the movable rod 210, and a coating disc 223 is arranged inside the telescopic plates 222.

[0037] It should be noted that when the diameter of the carbon fiber pipe is relatively small, the movable rod 210 drives the movement of the movable pipe 214, and the movable pipe 214 drives the movement of the second water outlet 218. Water is ejected onto the surface of the coating disc 223 through the first water outlet 212, and the outer wall of the carbon fiber pipe is coated through the coating disc 223, avoiding the formation of a water film directly on the pipe wall, which affects the grinding of the carbon fiber pipe. At the same time, the telescopic plates 222 can be telescoped to facilitate the coating of the carbon fiber pipe.

[0038] In an alternative embodiment, a limiting strip 37 is arranged on the auxiliary plate 31, and a second groove is arranged inside the rack 32, and the 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 moving out of the track and affecting the normal operation of the device.

[0040] In an alternative embodiment, a water storage tank is arranged on one side of the workbench 1, one end of the water storage tank is communicated with the protective shell 26, and clamping components are arranged at both ends of the workbench 1.

[0041] It should be noted that water is conveyed to the communication box 216 through the water storage tank for spraying. At the same time, the clamping components drive the carbon fiber pipe to rotate to facilitate grinding.

[0042] Working principle: Before using this device, the variable-diameter carbon fiber tube to be polished is clamped by the clamping components on both sides of the workbench 1. After clamping, the moving table 22 is driven to move to one end of the carbon fiber tube by the rotation of the first reciprocating screw rod 21. After moving to one end of the carbon fiber tube, the second reciprocating screw rod 24 is driven to rotate by the motor 23. The rotation of the second reciprocating screw rod 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 to move. The movement of the grinding disc 28 squeezes the inner carbon fiber tube. After the second reciprocating screw rod 24 rotates a certain distance and stops, a certain extrusion is generated between the grinding disc 28 and 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. The movement of the moving rod 210 drives the moving tube 214 to move inside the limiting sleeve 215. The movement of the moving tube 214 drives the second water outlet 218 to move. After starting the grinding, the water in the water storage tank enters the hose 217 through the connecting box 216 and then sprays out from the second water outlet 218. When the diameter of the carbon fiber tube contacted by the grinding disc 28 is larger, the distance that the grinding disc 28 drives the moving rod 210 to move is smaller, so that the moving distance of the moving tube 214 is shorter, and the water sprays out from the second water outlet 218 onto the carbon fiber tube for auxiliary grinding, reducing the splashing of dust during grinding and improving the grinding quality. When the diameter of the carbon fiber tube contacted by the grinding disc 28 is larger, the moving rod 210 drives the moving tube 214 to move a longer distance, so that the water in the second water outlet 218 sprays into the transfer box 220. Then the water enters the conveying pipe 221 from the moving rod 210 and sprays out from the first water outlets 212 at both ends through the telescopic pipe 211 and into the coating disc 223. By wetting the coating disc 223, the coating disc 223 wets and smears part of the water onto the carbon fiber tube, avoiding the formation of a water film on the carbon fiber tube when the water sprays out when the diameter of the carbon fiber tube is shorter, which affects the grinding quality of the carbon fiber tube. Thus, according to the diameter of the carbon fiber tube, the position of the sprayed water is adjusted to improve the grinding quality of the carbon fiber tube.

[0043] Meanwhile, when the device is in use, the first reciprocating lead screw 21 rotates to drive the moving table 22 to move, and then the second reciprocating lead screw 24 rotates to drive the grinding disc 28 to move to grind the carbon fiber tube. After grinding a section of the carbon fiber tube, the motor 23 drives the second reciprocating lead screw 24 to reverse to reset the grinding disc 28, and then the motor 23 rotates to drive the moving table 22 to move to grind the next section of the carbon fiber tube, so as to carry out the work of grinding the entire carbon fiber tube. At the same time, when the second reciprocating lead screw 24 rotates to drive the moving plate 25 to move, the moving plate 25 moves to drive the rack 32 to slide on the auxiliary plate 31. The movement of the rack 32 drives the one-way gear 34 to rotate, and the rotation of the one-way gear 34 drives the feeding rollers 35 on both sides to rotate, rotating the non-woven fabric roll placed on the feeding rollers 35, so that a certain amount of non-woven fabric falls from the non-woven fabric roll. When grinding with the grinding disc 28, two groups of cleaning hands 36 on one side of the grinding disc 28 squeeze the falling clean non-woven fabric, and cooperate with the rotation of the carbon fiber tube to clean the moisture and impurities attached to the carbon fiber tube, avoiding the influence of moisture and impurity residues on the grinding quality of the carbon fiber tube. At the same time, each time of grinding, the one-way gear 34 drives the feeding roller 35 to move a certain distance, so that each time the non-woven fabric in contact with the carbon fiber tube is clean, avoiding scratches on the outer wall of the carbon fiber tube caused by impurities remaining on the used non-woven fabric and affecting the quality of the carbon fiber tube.

[0044] Meanwhile, when the grinding disc 28 grinds the carbon fiber tube, it drives the moving rod 210 to move. The movement of the moving rod 210 drives the push plate 42 to move. The movement of the push plate 42 pushes the measuring plate 44, so that the measuring plate 44 slides on the limiting column 43. Each time of grinding, the measuring plate 44 will be pushed. Whether the grinding of the carbon fiber tubes on both sides is uniform can be observed through the scales on the scale plate 41. At the same time, through the scales on the scale plate 41, it can be judged whether the grinding of the carbon fiber tube meets the expected quality. When the scales of 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 expected scale, manual control can be carried out to end the grinding in advance to avoid over-grinding.

[0045] The rotation of the second reciprocating lead screw 24 drives the moving plate 25 to move on the limiting rod 29 to limit the moving plate 25 to prevent the moving plate 25 from moving out of the predetermined track and affecting the grinding of the device. The rack 32 slides on the limiting strip 37 to prevent the rack 32 from moving out of the track and affecting the normal operation of the device. Water is transported to the communication box 216 through the water storage tank for spraying. At the same time, the clamping component drives the carbon fiber tube to rotate to facilitate grinding.
