Description

Technical Field

[0001] The present invention relates to the field of carbon fiber composite materials, and more specifically, to a production device for carbon fiber composite materials. Background Art

[0002] Carbon fiber is mainly composed of carbon elements and has the characteristics of high temperature resistance, friction resistance, thermal conductivity and corrosion resistance. It has a fibrous appearance, is soft, and can be processed into various fabrics. The carbon fiber tube made of carbon fiber composite material is also called carbon fiber tube, which is made of carbon fiber composite material pre-impregnated with polymer resin and then heated and cured and wound. Carbon fiber composite material has the characteristic of light weight, so high-end bicycles mostly use carbon fiber composite material to make seat tubes. In order to improve the surface smoothness of the carbon fiber seat tube, it is usually necessary to grind and polish the surface of the carbon fiber seat rod.

[0003] The patent with publication number CN114800074A discloses an automatic carbon fiber polishing device, including a base plate, a clamping device is fixedly connected to the upper end surface of the base plate, a polishing mechanism is clamped in the middle of the clamping device, one end of the clamping device is fixedly connected to a guide mechanism with adjustable telescopic length, a cleaning mechanism is fixedly connected to the bottom of the guide mechanism, a polishing mechanism is provided at one end of the cleaning mechanism close to the clamping device, the cleaning mechanism is sleeved on the outer end surface of the polishing mechanism, and a liquid storage device is fixedly connected to the upper end surface of the clamping device, the liquid storage device is connected to a connecting hose, the end of the connecting hose facing away from the liquid storage device is connected to the guide mechanism, and the guide mechanism is connected to the cleaning mechanism.

[0004] The grinding device in the above scheme uses a clamping device to fix and position the workpiece, and a cleaning mechanism is provided on the outer end face of the workpiece. The cleaning mechanism is controlled by the sliding of the guiding mechanism, and a grinding mechanism is provided on the end face of the cleaning mechanism. The sliding of the cleaning mechanism drives the grinding mechanism to grind and polish the surface of the workpiece, and the moving direction of the grinding mechanism is the same as the axial direction of the workpiece, which effectively avoids the breakage of the internal fibers of the workpiece and causes the strength to be reduced. At the same time, the cleaning mechanism can clean the surface of the workpiece during movement, and the cleaning mechanism is connected to the liquid storage device through a connecting hose, which effectively reduces the damage to the health of the operator caused by the fibers generated after the workpiece is polished.

[0005] Although this grinding device can effectively reduce the health damage to workers during grinding, the clamping device used during grinding cannot adjust the clamping force according to the carbon fiber composite materials of different strengths. If the clamping force is too large, it is easy to cause damage to the carbon fiber seat tube. If the clamping force is too small, the carbon fiber seat tube is easy to fall off during grinding.

When the transmission roller 13 rotates, the polishing belt 16 will be driven by the transmission roller 2 14 and the transmission roller 3 15 to start polishing and grinding the carbon fiber seat tube 10. When the motor 1 3 rotates, the transmission ring 22 will be driven to rotate and the transmission roller 4 21 will be driven to rotate through the transmission belt 23. When the transmission roller 4 21 starts to rotate, the threaded rod 1 20 will be driven to rotate, and the positioning plate 12 will start to move toward the side of the fixed plate 2, so that the carbon fiber seat tube 10 can be evenly polished and polished. After the polishing is completed, the carbon fiber seat tube 10 is removed, and the motor 1 3 is reversed to reset the positioning plate 12.

[0030] like Figure 1 , Figure 6 , Figure 7As shown, the placing table 1 is fixedly connected with a fixing frame 24, and a limiting rod 25 is fixedly connected with the fixing frame 24. A sliding plate 26 is slidably connected between the limiting rod 25 and the fixing frame 24, and a sliding block 27 is slidably connected to the sliding plate 26. A threaded rod 28 for pressing against the sliding block 27 is threadedly connected to the sliding plate 26, and a sliding rod 29 is slidably connected inside the sliding block 27. One end of the sliding rod 29 is fixedly connected to a limiting block 30 inside the sliding block 27, and the other end of the sliding rod 29 is detachably connected with a grinding block 31. After the grinding block 31 is excessively worn, it can be replaced. The sliding rod 29 is sleeved with a pressure spring 32 between the grinding block 31 and the sliding block 27.

When the grinding block 31 and the carbon fiber seat tube 10 are in contact with each other, the tension spring 33 is in a deformed state, the sliding plate 26 and the sliding plate 2 34 are in contact with each other, a clamping block 36 is slidably connected to the sliding plate 2 34, and a groove 37 for the clamping block 7 to be placed is provided on the fixing frame 24. When the clamping block 36 is in the groove 37, the pressure spring 2 35 is in a deformed state.

[0031] like Figure 1 , Figure 6 , Figure 7 As shown, when one end of the carbon fiber seat tube 10 is attached to the positioning plate 4, the threaded rod 28 is rotated so that the threaded rod 28 does not contact the sliding block 27, and then the sliding plate 1 26 is pulled and the grinding block 31 is slid, and the cone top of the grinding block 31 is placed in the carbon fiber seat tube 10, and then the tension spring 33 makes the grinding block 31 consistent with the center point of the carbon fiber seat tube 10, and makes the grinding block 31 always contact with the carbon fiber seat tube 10. At this time, the tension spring 33 is reset for a distance, and the pressure spring 1 32 is in a normal state. Then the threaded rod 28 is rotated in the opposite direction to make the threaded rod 28 press against the sliding block 27 to fix the sliding block 27. At this time, the carbon fiber The rotation of the seat tube 10 will drive the grinding block 31 to rotate, and then pull the block 36 out of the groove 37, and the pressure spring 2 35 starts to reset and drives the sliding plate 2 34 to fit with the sliding plate 1 26. At this time, the tension spring 33 is reset again for a distance, and the pressure spring 1 32 is in a contracted state. The sliding rod 29 and the limit block 30 move toward the side of the sliding plate 1 26 and contact the inner bottom side of the sliding block 27 to restrict the grinding block 31. At this time, the rotation of the carbon fiber seat tube 10 will grind the cross section of the carbon fiber seat tube 10. After the grinding is completed, slide the sliding plate 2 34, and place the block 36 into the groove 37, and then grind the outer wall normally.

[0032] like Figure 1 , Figure 8, Fig. 9 As shown, a suction fan 38 is fixedly connected to the positioning plate 12, and a suction port 39 is fixedly connected to the suction fan 38. The width of the suction port 39 is consistent with the width of the polishing belt 16. The carbon fiber seat tube 10 is located between the polishing belt 16 and the suction port 39. The suction fan 38 is turned on synchronously during polishing to remove the carbon fiber powder through the suction port 39. A stabilizing rod 40 is fixedly connected to the placement table 1, and the other end of the stabilizing rod 40 is fixedly connected to the fixing plate 2. The positioning plate 12 is slidably connected to the stabilizing rod 40 to ensure that the positioning plate 12 can be used normally and avoid tilting due to excessive weight borne by the positioning plate 12.

[0033] Working principle: when the carbon fiber seat tube 10 needs to be polished, one end of the carbon fiber seat tube 10 can be attached to the positioning plate 4, and then the electric push rods 5 are started to shrink, driving the fixing block 6, the spring telescopic rod 1 9, the positioning block 8 and the clamping block 7, and the clamping blocks 7 are brought close to each other to preliminarily fix the carbon fiber seat tube 10. After the fixation is completed, the electric push rod 5 shrinks again according to the tensile strength of the carbon fiber seat tube 10, and drives the spring telescopic rod 1 9 to shrink and apply corresponding pressure to the carbon fiber seat tube 10, and then the fixing operation of the carbon fiber seat tube 10 is completed, and then the threaded rod 28 is rotated to make the threaded rod 2 28 is not in contact with the sliding block 27, then the sliding plate 1 26 is pulled and the grinding block 31 is slid, the cone top of the grinding block 31 is placed in the carbon fiber seat tube 10, and the grinding block 31 is always in contact with the carbon fiber seat tube 10, then the threaded rod 28 is rotated in the opposite direction, so that the threaded rod 28 is pressed against the sliding block 27 to fix the sliding block 27, and then the clamping block 36 is pulled out of the groove 37, and the pressure spring 2 35 starts to reset and drives the sliding plate 2 34 to fit with the sliding plate 1 26. At this time, the tension spring 33 is reset again for a distance, the pressure spring 1 32 is in a contracted state, and the sliding rod 29 and the limit block 30 move toward the sliding plate 1 26. The first side of the carbon fiber seat tube 10 moves and contacts the inner bottom side of the sliding block 27 so that the grinding block 31 is restricted. At this time, the motor 13 and the suction fan 38 are turned on. The motor 13 drives the carbon fiber seat tube 10 to rotate and grind the cross section of the carbon fiber seat tube 10. After the grinding is completed, the motor 13 is turned off, the sliding plate 2 34 is slid, and the block 36 is placed in the groove 37. Then the motor 13 and the motor 2 17 are synchronously turned on to drive the carbon fiber seat tube 10 and the transmission roller 1 13 to start rotating. When the transmission roller 13 rotates, the transmission roller 2 14 and the transmission roller 3 15 drive the polishing belt 16 to start polishing the carbon fiber seat tube 10. When the motor 3 rotates, the transmission ring 22 is driven to rotate and the transmission roller 21 is driven to start rotating through the transmission belt 23. When the transmission roller 21 starts to rotate, the threaded rod 20 is driven to start rotating, and the positioning plate 12 starts to move toward the side of the fixed plate 2. In this way, when grinding the outer wall of the carbon fiber seat tube 10, the clamping force can be adjusted according to the tensile strength of the carbon fiber seat tube 10 to avoid damage to the carbon fiber seat tube 10 or the seat tube falling off during grinding. The outer walls and cross-sections of carbon fiber seat tubes 10 with different diameters can be ground, and the ground carbon fiber powder can be processed simultaneously.
