Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of carbon fiber product processing, in particular to an edge grinding device for carbon fiber product processing. Background Art
[0002] Carbon fiber is an advanced composite material with high strength, high modulus and low density. It is usually made of cellulose material with a carbon content of more than 90% after high-temperature carbonization. It not only has excellent mechanical properties, but also has excellent properties such as corrosion resistance, high temperature resistance, electrical conductivity and thermal conductivity. Therefore, it has been widely used in aerospace, automobile manufacturing, sports goods, construction engineering and other fields.
[0003] With the continuous development of UAV technology, the requirements for UAV performance are getting higher and higher. Carbon fiber has become an ideal material for UAV manufacturing due to its light weight and high strength. The application of carbon fiber in UAVs is mainly concentrated in the fuselage structure, propellers, brackets and landing gear. These parts vary in size, ranging from propellers as small as a few centimeters to fuselage parts as large as tens of centimeters. As the fuselage structure material of UAVs, carbon fiber materials can effectively improve the flight performance and endurance of UAVs. Carbon fiber propellers have the advantages of light weight, high strength and good rigidity, and can provide higher power efficiency and more stable flight performance.
[0004] During the manufacturing process, the carbon sheet needs to be laid in the mold, and then the two molds clamp the carbon sheet and send it into the autoclave. Under high temperature and high pressure, the carbon sheet first melts a part and then hardens to get the same shape as the mold. When the mold is opened, there are usually extra carbon sheets on the edge of the product. This is for the integrity of the product. The product is then cut to preliminarily remove the extra carbon sheets on the outer circle, and then the product is polished according to the precision requirements to ensure surface smoothness and dimensional accuracy. The processing of small carbon fiber workpieces mainly relies on handheld small edge grinding machines. However, due to the different depths of the inner concave parts of the workpiece, in order to ensure the polishing effect, the operator needs to frequently replace the polishing rods of different lengths, which is not only time-consuming, but also increases the complexity of the operation; when polishing the flat workpiece, the operator needs to pay attention to the polishing height at all times to prevent damage to the workpiece due to excessive polishing. Utility Model Content
[0005] In order to overcome the disadvantage that the grinding rod needs to be replaced continuously due to the different sizes of different parts and to ensure the grinding effect, the utility model provides an edge grinding and adjusting device for processing carbon fiber products.
[0006] An edge grinding device for processing carbon fiber products includes a mounting sleeve, a motor, a connecting shaft and a grinding rod. The motor is mounted at the bottom of the mounting sleeve. The output shaft of the motor is connected to the connecting shaft, which is fixed at the opening of the mounting sleeve.

A torsion spring is arranged at the connection between the clamping plate and the connecting block. One end of the torsion spring is connected to the connecting block, and the other end is connected to the clamping plate.
[0008] In one of the embodiments, the support assembly includes a guide sleeve, a limit plate and an insertion rod. The guide sleeve is connected to the side of the limit ring at the front end of the mounting sleeve. The limit plate is slidably connected to the guide sleeve. A positioning hole is opened in the middle of the guide sleeve. A plurality of adjustment holes are opened on the limit plate. The insertion rod passes through the positioning hole and is inserted into the adjustment hole.
[0009] In one of the embodiments, it also includes a protective shell. The mounting sleeve is in the shape of a hexagonal prism as a whole, and a circular groove is arranged at the front end.

Whether it is for small carbon fiber workpieces or parts with concave parts of different depths, it can ensure that the grinding rod is ground at the best angle and distance, thereby improving the grinding accuracy and consistency.
[0014] 2. By adjusting the support components, the operator can control the grinding height more accurately, effectively preventing damage to the workpiece due to excessive grinding, and improving the yield and safety of the product.

DETAILED DESCRIPTION
[0022] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.
[0023] Embodiment: An edge grinding device for processing carbon fiber products, such as Figure 1-Figure 6 As shown, it includes a mounting sleeve 1, a motor 2, a connecting shaft 3 and a polishing rod 4. The motor 2 is installed at the bottom of the mounting sleeve 1. The output shaft of the motor 2 is connected to the connecting shaft 3, and the connecting shaft 3 is fixed at the opening of the mounting sleeve 1. The other end of the connecting shaft 3 is connected to the polishing rod 4. The surface of the polishing rod 4 is rough. A cylinder is provided in the middle part of the connecting shaft 3, one part of which is sleeved on the front end of the mounting sleeve 1, and the other part is sleeved with a protective shell 13, which is used for polishing carbon fiber products. It also includes an adjustment component and a support component. The mounting sleeve 1 is provided with an adjustment component for adjusting the effective polishing distance of the polishing rod 4, and the adjustment component is connected to a support component for adjusting the horizontal height of the polishing rod 4 during horizontal polishing.
[0024] like Figure 3 and Figure 4 As shown, the adjustment component includes a limit ring 5, a sliding sleeve 6, a connecting block 7, a clamping plate 8 and a torsion spring 9. The front and rear ends of the mounting sleeve 1 are connected to the limit ring 5, the sliding sleeve 6 is slidably connected to the limit ring 5, a plurality of limit holes 51 are opened on the sliding sleeve 6 along the vertical direction, and limit holes 51 are opened on both sides of the limit ring 5. The connecting block 7 is fixedly connected to the limit ring 5, one end of the clamping plate 8 is hinged to the connecting block 7, the middle of the clamping plate 8 is attached to the outer surface of the sliding sleeve 6, and the other end of the clamping plate 8 is inserted into the limit hole 51 of the limit ring 5 and the sliding sleeve 6. A torsion spring 9 is arranged at the connection between the clamping plate 8 and the connecting block 7, one end of the torsion spring 9 is connected to the connecting block 7, and the other end is connected to the clamping plate 8.
[0025] like Figure 5 and Figure 6 As shown, the support assembly includes a guide sleeve 10, a limit plate 11 and an insertion rod 12. The limit ring 5 at the front end of the mounting sleeve 1 is connected to the guide sleeve 10 on the side, and the limit plate 11 is slidably connected to the guide sleeve 10. A positioning hole 101 is opened in the middle of the guide sleeve 10, and a plurality of adjustment holes 111 are opened on the limit plate 11. The insertion rod 12 passes through the positioning hole 101 and is inserted into the adjustment hole 111. The insertion rod 12 and the positioning hole 101 have an interference fit, and the insertion rod 12 and the adjustment hole 111 have a transition fit.
[0026] The staff opens the cover at the bottom of the installation sleeve 1, puts the motor 2 into the installation sleeve 1, covers the cover, and installs the connecting shaft 3 and the polishing rod 4 in turn. The staff holds the installation sleeve 1, then turns on the motor 2, transmits the power through the connecting shaft 3, and the polishing rod 4 rotates to polish the carbon fiber product. When it is necessary to polish "bottle cap" type parts, the depth of different parts is different. Here, "bottle cap" refers to parts with grooves and obvious edges. If the hand-held position is too far from the polishing position, the polishing accuracy cannot be guaranteed. Therefore, for "bottle caps" with a smaller depth, turn up the card on both sides. Plate 8, the card plate 8 leaves the limiting hole 51 of the limiting ring 5 and the sliding sleeve 6, twists the torsion spring 9, pushes the sliding sleeve 6 forward, and the distance between the front end of the sliding sleeve 6 and the front end of the grinding rod 4 is reduced, so that the distance between the hand-held position and the grinding position is reduced, and then the card plate 8 is released. Under the action of the return torque of the torsion spring 9, the card plate 8 is attached to the sliding sleeve 6, and then the staff pushes the card plate 8, and the other end of the plate is inserted into the limiting hole 51 of the limiting ring 5 and the limiting hole 51 of the sliding sleeve 6, so as to fix the sliding sleeve 6. At this time, when grinding the carbon fiber product, it is easier to control the grinding distance;
[0027] When grinding the edge of the "bottle cap", according to the height of the "bottle cap", the rod 12 is pulled out. After the rod 12 leaves the guide sleeve 10, the limit plate 11 is adjusted up and down. The limit plate 11 supports the sliding sleeve 6 through the guide sleeve 10, and the sliding sleeve 6 is rotated or moved horizontally, so that the edge of the "bottle cap" can be ground and the grinding can be guaranteed to be smooth. After adjusting the height, the rod 12 passes through the positioning hole 101 of the guide sleeve 10 and is inserted into the adjusting hole 111 of the limit plate 11. Since the rod 12 and the positioning hole 101 have an interference fit and the rod 12 and the adjusting hole 111 have a transition fit, the rod 12 needs to overcome the squeezing force of the guide sleeve 10 when passing through the positioning hole 101, and the end of the rod 12 can remain on the guide sleeve 10 and is not completely pulled out, so that it will not fall off. After sliding the limit plate 11, the rod 12 is pushed in again to complete the adjustment of the grinding height.
[0028] like Figure 1 and Figure 2 As shown, it also includes a protective shell 13. The mounting sleeve 1 is a hexagonal prism as a whole, and a circular groove is arranged at the front end. The middle cylindrical part of the connecting shaft 3 is clamped in the front end groove of the mounting sleeve 1, and the protective shell 13 is clamped on the middle circular part of the connecting shaft 3 and wraps the grinding rod 4.
[0029] like Figure 5 and Figure 6 As shown, a pulley 14 is also included. The bottom of the limiting plate 11 is connected to the pulley 14, and the rotation direction of the pulley 14 is consistent with the horizontal grinding direction of the grinding rod 4.
[0030] like Figure 5 and Figure 6 As shown, it also includes a magnetic sheet 15 , which is connected to the guide sleeve 10 and is used to magnetically attract the insertion rod 12 . The diameter of the circular hole in the middle of the magnetic sheet 15 is larger than the diameter of the adjustment hole 111 .
[0031] After the grinding work is completed, or after the use of this type of grinding rod 4 is completed, the protective shell 13 is put on to protect the grinding rod 4. When it is similar to a row of "bottle caps", that is, the single body is longer and the top part needs to be polished, when the sliding sleeve 6 is pushed to move, the pulley 14 rolls at the bottom of the limit plate 11, and the sliding friction with the supporting surface is converted into rolling friction. Long-term work can effectively relieve the labor intensity of the staff. The magnetic suction sheet 15 can absorb the insertion rod 12, and the insertion rod 12 can also be adsorbed on the magnetic suction sheet 15 when it is completely pulled out to prevent the insertion rod 12 from falling.
[0032] The above description is only an example of the implementation of the present invention and is not intended to limit the present invention. Any equivalent replacement made within the principle of the present invention shall be included in the protection scope of the present invention. The contents not elaborated in the present invention belong to the existing technology known to the technicians in this professional field.
