Description

Technical Field

[0001] This utility model relates to the field of carbon fiber skateboard processing technology, and more specifically, to a grinding device for processing carbon fiber skateboards. Background Technology

[0002] Carbon fiber skateboards are skateboards made using carbon fiber composite materials. Compared to traditional wooden or metal skateboards, carbon fiber skateboards have significant advantages in weight, strength, and rigidity. The low density of carbon fiber allows for the manufacture of lighter skateboards while maintaining sufficient strength and rigidity, which is crucial for improving the skateboard's responsiveness and durability. In addition, the high elastic modulus of carbon fiber allows for better shock absorption, providing a more comfortable riding experience. Therefore, carbon fiber skateboards are favored by skateboard enthusiasts due to their superior performance and unique design.

[0003] In the processing of carbon fiber skateboards, in order to improve the surface quality, the outer surface of the carbon fiber skateboard usually needs to be polished. However, because there are many tiny pores on the surface of carbon fiber skateboards, a lot of dust can easily enter the pores of the material surface during polishing, causing blockages that are extremely difficult to clean. Moreover, since the two ends of carbon fiber skateboards are curved, the equipment that can perform curved surface polishing is not only large in size but also complex in function, resulting in higher operating costs compared to the processing of carbon fiber skateboards. Therefore, polishing is still mostly done manually, which affects the processing efficiency and effect of carbon fiber skateboards. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a grinding device for processing carbon fiber skateboards, which solves the problem that the surface of existing carbon fiber skateboards has many small holes, and during the grinding process, a lot of dust can easily enter the pores of the material surface and form blockages, which are extremely difficult to clean. In addition, since the two ends of the carbon fiber skateboard are curved, the equipment that can achieve curved surface grinding is not only large in size but also complex in function, resulting in higher operating costs compared to the processing of carbon fiber skateboards.

The clamping blocks at both ends are movably connected to both sides of the skateboard base plate, and the length of the clamping blocks is the same as the length of the plane of the skateboard base plate.

[0009] The second movable frame has a groove on its top, and a limiting plate is installed inside the groove. The top of the second movable frame is threaded with a first fixing bolt. The second movable frame and the limiting plate are fixedly connected by the first fixing bolt. The limiting plate has a limiting groove inside, and the shape of the limiting groove corresponds to the shape of the skateboard base plate.

[0010] The base frame is fixedly mounted on one side near the second movable frame. A positioning plate is fixedly mounted on the middle of the horizontal direction of the fixed frame. A fixed rod is fixedly mounted on the middle of the vertical direction of the fixed frame. A top rod is movably sleeved on the outer surface of the upper end of the fixed rod.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. By setting up a water spray rack and water pump, water is used to cool down the carbon fiber skateboard during the polishing process, so as to avoid the carbon fiber skateboard being too strong and rigid, which could easily cause overheating during polishing and affect the polishing effect.

[0015] 2. By setting the height of the support bar higher than the height of the first moving frame, the limiting rod is fixedly installed between the support bar and the first moving frame in an inclined position, thereby making the clamping blocks at both ends in an inclined state and the skateboard bottom plate in an inclined state. Water flows over the high part of the skateboard bottom plate and automatically flows to the low part of the skateboard bottom plate, thereby cooling the skateboard bottom plate while flowing quickly and carrying away the dust on the surface of the skateboard bottom plate, reducing the amount of dust entering the pores on the surface of the skateboard bottom plate, and thus reducing the difficulty of cleaning the skateboard bottom plate.

[0016] 3. By setting up a guide chute, the water flows through the guide chute and slides into the water storage chamber. The water is filtered by the filter screen, and dust is intercepted inside the filter screen, thus enabling water recycling. By pulling the handle groove, the sludge collection box can be pulled out from inside the base frame for easy cleaning of the filter screen.

[0017] 4. During the movement of the second moving frame, the limiting plate moves and limits the limiting roller through the limiting groove. When the limiting roller moves to the arc surface of the limiting groove, the limiting roller pushes the bottom rod to rise and fall inside the fixed frame, thereby controlling the rise and fall of the support frame, so that the grinding roller automatically adjusts the grinding height of the grinding roller according to the arc surface of the slide plate.

[0018] 5. This polishing device has a simple structure and low operating cost. It can polish both sides of carbon fiber skateboards and has a wider range of applications. Attached Figure Description

Detailed Implementation

[0026] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0027] As attached Figure 1 - Appendix Figure 3 The present invention provides a grinding device for processing carbon fiber skateboards, including a grinding machine body 1, a clamping component 2 slidably mounted on the top of the grinding machine body 1, a working component 3 fixedly mounted on one side of the top of the grinding machine body 1, and a skateboard base plate 4 placed inside the clamping component 2.

[0028] As attached Figure 3 As shown, the grinding machine body 1 includes a base frame 11. Sliding grooves 12 are provided on both sides of the top of the base frame 11. A guide groove 13 is provided on the top of the base frame 11. A water inlet groove 14 is provided on the left side of the top of the base frame 11. A water storage chamber 18 is provided inside the base frame 11. The left side of the guide groove 13 is connected to the water storage chamber 18 through the water inlet groove 14. A slag collection box 15 is movably sleeved on the left side of the upper end of the base frame 11. A filter screen 16 is fixedly installed inside the slag collection box 15. A handle groove 17 is provided on the left side of the slag collection box 15. The filter screen 16 is located in the middle of the water inlet groove 14. A water pump 19 is fixedly installed on the right side of the base frame 11. One end of the water pump 19 is fixedly connected to a water inlet pipe 110. One end of the water inlet pipe 110 is located inside the water storage chamber 18.

[0029] By setting the guide chute 13, the water flows through the guide chute 13 and slides into the water storage chamber 18 through the water inlet chute 14. The water is filtered by the filter screen 16, and the dust is intercepted inside the filter screen 16, so that the water can be recycled. By pulling the handle groove 17, the sludge box 15 can be pulled out from the base frame 11 for easy cleaning of the filter screen 16.

[0030] As attached Figure 4 As shown, the clamping assembly 2 includes two moving motors 21, both of which are fixedly installed on one side of the base frame 11. A rotating screw 22 is fixedly installed on one side of the moving motor 21. The rotating screw 22 is rotatably installed inside the sliding groove 12. A first moving frame 23 is threadedly installed on the outer surface of the left rotating screw 22, and a second moving frame 24 is threadedly installed on the outer surface of the right rotating screw 22. A support bar 28 is fixedly installed on the left side of the second moving frame 24. The first moving frame 23 and the second moving frame 24 are slidably installed inside the sliding grooves 12 on both sides of the top of the base frame 11.

[0031] Limiting rods 29 are fixedly installed at both ends of the support bar 28 and the first movable frame 23. The height of the support bar 28 is higher than the height of the first movable frame 23. The limiting rods 29 are fixedly installed at an incline between the support bar 28 and the first movable frame 23. A bidirectional screw 210 is rotatably installed in the middle of the first movable frame 23 and the support bar 28. A rotating knob 211 is fixedly installed on the left side of the bidirectional screw 210. Clamping blocks 212 are movably sleeved on the outer surfaces of both ends of the limiting rod 29. The middle parts of the clamping blocks 212 are threaded onto the outer surfaces of both ends of the bidirectional screw 210. The clamping blocks 212 are movably connected to both sides of the skateboard base plate 4, and the length of the clamping blocks 212 is the same as the length of the plane of the skateboard base plate 4.

[0032] By setting the height of the support bar 28 to be higher than the height of the first movable frame 23, the limiting rod 29 is fixedly installed at an angle between the support bar 28 and the first movable frame 23, thereby making the clamping blocks 212 at both ends in an inclined state. The skateboard base plate 4 is placed between the clamping blocks 212 on both sides. By rotating the rotating knob 211, the clamping blocks 212 at both ends clamp the skateboard base plate 4. At this time, the skateboard base plate 4 is in an inclined state, which facilitates the water flow to quickly flow away from the surface of the skateboard base plate 4 and carry away the dust on the surface of the skateboard base plate 4.

[0033] By setting the length of the clamping block 212 to be the same as the length of the plane of the skateboard base plate 4, the skateboard base plate 4 is placed directly between the clamping blocks 212, so that the arc surfaces at both ends are suspended in the air, automatically positioning and fixing the skateboard base plate 4, thus facilitating the processing of the skateboard base plate 4.

[0034] As attached Figure 4As shown, the top of the second movable frame 24 has a groove, and a limiting plate 25 is installed inside the groove. The top of the second movable frame 24 is threaded with a first fixing bolt 27. The second movable frame 24 and the limiting plate 25 are fixedly connected by the first fixing bolt 27. A limiting groove 26 is opened inside the limiting plate 25. The shape of the limiting groove 26 corresponds to the shape of the slide plate base plate 4.

[0035] Utilizing the shape of the limiting groove 26, when the moving motors 21 at both ends synchronously control the rotating screw 22 to rotate, the first moving frame 23 and the second moving frame 24 move synchronously, causing the limiting plate 25 to move. Through the limiting groove 26, the limiting roller 305 is limited, causing the top rod 301 and the bottom rod 303 to rise and fall inside the fixed frame 31, thereby controlling the rise and fall of the support frame 34, so that the grinding roller 38 automatically adjusts the grinding height according to the shape of the slide plate base plate 4.

[0036] By setting a groove on the top of the second movable frame 24, the limiting plate 25 can be detached from the inside of the second movable frame 24 by the first fixing bolt 27. When it is necessary to polish the back of the skateboard bottom plate 4, the limiting plate 25 is removed by the first fixing bolt 27 and installed in reverse so that the arc surfaces at both ends of the limiting plate 25 face down. At this time, the limiting plate 25 moves and limits the limiting roller 305 by the limiting groove 26, so that the top rod 301 and the bottom rod 303 rise and fall inside the fixed frame 31, thereby controlling the rise and fall of the support frame 34, so that the polishing roller 38 automatically adjusts the back of the polishing roller 38 to polish according to the shape of the skateboard bottom plate 4.

[0037] As attached Figure 5 and attached Figure 6 As shown, a fixed frame 31 is fixedly installed on the side of the base frame 11 near the second movable frame 24. A positioning plate 33 is fixedly installed in the middle of the horizontal direction of the fixed frame 31. A fixed rod 32 is fixedly installed in the middle of the vertical direction of the fixed frame 31. A top rod 301 is movably sleeved on the outer surface of the upper end of the fixed rod 32. Movable rods 302 are fixedly installed at both ends of the bottom of the top rod 301. Bottom rods 303 are fixedly installed at the bottom of the two movable rods 302. The movable rods 302 are movably sleeved inside the positioning plate 33. Return springs 306 are movably sleeved on the outer surfaces of both ends of the movable rods 302. The two return springs 306 are located between the top rod 301 and the positioning plate 33 and between the bottom rod 303 and the positioning plate 33, respectively.

[0038] The top of the top rod 301 is fixedly mounted with a support frame 34. Lifting cylinders 35 are fixedly mounted on both sides of the top of the support frame 34. A grinding frame 36 is fixedly mounted at the bottom of the lifting cylinders 35. A grinding motor 37 is fixedly mounted on the left side of the grinding frame 36. A grinding roller 38 is fixedly mounted on one side of the grinding motor 37. The grinding roller 38 is rotatably mounted inside the grinding frame 36 and is inclined in a manner corresponding to the limit rod 29. A water spray frame 310 is fixedly mounted on the right side of the top of the grinding frame 36. A water outlet pipe 111 is fixedly connected to the right side of the water spray frame 310. One end of the water outlet pipe 111 is connected to the water pump 19.

[0039] The water spray rack 310 is set on the polishing rack 36 near the second movable rack 24, and the height of the support bar 28 is higher than the height of the first movable rack 23. At this time, the water spray rack 310 is located at the high point of the inclined skateboard base plate 4. The water flows through the high point of the skateboard base plate 4 and automatically flows to the low point of the skateboard base plate 4, thereby cooling the skateboard base plate 4 and flowing quickly to remove dust from the surface of the skateboard base plate 4, reducing the amount of dust entering the pores on the surface of the skateboard base plate 4, and thus reducing the difficulty of cleaning the skateboard base plate 4.

[0040] The bottom rod 303 has support shafts 304 movably sleeved on both sides inside. Limiting rollers 305 are rotatably installed on the outer surface of the left side of the support shafts 304 at both ends. The limiting rollers 305 are slidably installed inside the limiting grooves 26. A connecting plate 307 is fixedly installed on the right side of the support shafts 304 at both ends. The connecting plate 307 is threaded with a second fixing bolt 308. The connecting plate 307 is fixedly connected to the bottom rod 303 through the second fixing bolt 308.

[0041] By setting two support shafts 304 to connect one end to a connecting plate 307, and the connecting plate 307 is fixedly installed on one side of the bottom rod 303 by the second fixing bolt 308, when it is necessary to change the direction of the limiting plate 25, the connecting plate 307 is pulled by rotating the second fixing bolt 308, so that the limiting roller 305 moves out of the limiting groove 26, thus avoiding interference between the limiting plate 25 and the limiting roller 305 when the limiting plate 25 is taken out, which would affect the removal and installation of the limiting plate 25.

[0042] The working process of this utility model is as follows:

[0043] In use, the skateboard base plate 4 is placed between the clamping blocks 212 at both ends. By rotating the rotating knob 211, the clamping blocks 212 at both ends are brought closer together to clamp and fix the skateboard base plate 4. By controlling the extension of the lifting cylinder 35, the grinding frame 36 is lowered, and the grinding roller 38 is placed against the outer surface of the skateboard base plate 4. The grinding motor 37 is started, so that the grinding roller 38 grinds the outer surface of the skateboard base plate 4. At the same time, the water pump 19 works, so that the water in the water storage chamber 18 is sprayed out from the water spray frame 310 through the water inlet pipe 110 and the water outlet pipe 111. Due to the height of the support bar 28, The height is higher than that of the first movable frame 23, so that the limiting rod 29 is fixedly installed in an inclined position between the support bar 28 and the first movable frame 23, thereby making the clamping blocks 212 at both ends in an inclined state. The skateboard bottom plate 4 is placed between the clamping blocks 212 on both sides. By rotating the rotating knob 211, the clamping blocks 212 at both ends clamp the skateboard bottom plate 4. At this time, the skateboard bottom plate 4 is in an inclined state. The water flows through the high part of the skateboard bottom plate 4 and will automatically flow to the low part of the skateboard bottom plate 4, thereby cooling the skateboard bottom plate 4 while flowing quickly and carrying away the dust on the surface of the skateboard bottom plate 4.

[0044] Water containing dust will flow into the interior of the guide chute 13, and through the action of the guide chute 13, slide down through the water inlet chute 14 into the interior of the water storage chamber 18, and be filtered by the filter screen 16, trapping the dust inside the filter screen 16, thereby enabling the water to be recycled. By pulling the handle groove 17, the sludge collection box 15 can be pulled out from the interior of the base frame 11, making it easy to clean the filter screen 16.

[0045] During the polishing process, the two moving motors 21 start synchronously, controlling the rotating screw 22 to rotate, thereby causing the first moving frame 23 and the second moving frame 24 to move synchronously, driving the skateboard base plate 4 to move. During the movement of the second moving frame 24, the limiting plate 25 moves, limiting the limiting roller 305 through the limiting groove 26. When the limiting roller 305 moves to the arc surface of the limiting groove 26, the limiting roller 305 pushes the bottom rod 303 to rise and fall inside the fixed frame 31, thereby controlling the rise and fall of the support frame 34, so that the polishing roller 38 automatically adjusts the polishing height of the polishing roller 38 according to the arc surface of the skateboard base plate 4.

[0046] By setting a groove on the top of the second movable frame 24, the limiting plate 25 can be detached from the inside of the second movable frame 24 by the first fixing bolt 27. When it is necessary to grind the back of the skateboard bottom plate 4, the first fixing bolt 27 is rotated so that one end of the first fixing bolt 27 is disengaged from the inside of the limiting plate 25. In addition, by rotating the second fixing bolt 308, the connecting plate 307 is pulled so that the limiting roller 305 moves out of the inside of the limiting groove 26. The limiting plate 25 is taken out upward and installed in reverse so that the arc surfaces at both ends of the limiting plate 25 face downward. At this time, the limiting plate 25 moves and the limiting roller 305 is limited by the limiting groove 26, so that the top rod 301 and the bottom rod 303 rise and fall inside the fixed frame 31, thereby controlling the rise and fall of the support frame 34, so that the grinding roller 38 automatically adjusts the back of the grinding roller 38 to grind according to the shape of the skateboard bottom plate 4.

Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
