DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0024] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] When replacing the blade of the above device, the blade needs to be pressed onto the blade body with the fingertips, and then the blade is fixed to the blade body with bolts. If the hand accidentally touches the sharp edge of the blade, or the hand is squeezed due to excessive force during the installation process, it may cause hand injury.

[0027] like Figures 1 to 4 The utility model provides a high-precision alloy soundboard gasket discarding milling cutter.

[0028] Specifically, by Figure 1-Figure 4 A high-precision alloy soundboard gasket discarded milling cutter is provided, comprising a cutter body 1, two blades 2 are arranged on the cutter body 1, two plug blocks 3 are fixedly installed on one side of the blade 2, the outer wall of the plug block 3 is integrally formed with two rubber sheets 4, the two rubber sheets 4 are symmetrically installed on the outer wall of the plug block 3, the cutter body 1 is provided with a socket 5 matched with the plug block 3, the blade 2 is provided with a first through hole 10, the blade 2 is provided with a hexagon socket head screw 8, the cutter body 1 is provided with a threaded hole 7 matched with the hexagon socket head screw 8, and two magnets 6 are installed on the cutter body 1.

[0029] In the utility model, the staff holds the connecting rod 12 with one hand, and aligns the insert block 3 with the socket 5 on the blade body 1 with the other hand, and pushes the blade 2 to the direction of the blade body 1. The material of the blade 2 is high-quality steel, because steel is mainly composed of iron, and iron has good magnetism, so it is attracted by the magnet 6. The suction force of the magnet 6 on the blade 2 helps to push the insert block 3 to the inside of the socket 5. The rubber sheet 4 contacts the inner wall of the socket 5, which increases the friction, so that the insert block 3 is not easy to fall off from the inside of the socket 5. With mutual cooperation, the blade 2 can be better fixed on one side of the knife body 1. At this time, the staff only needs to hold the connecting rod 12 with one hand. There is no need for the staff to use the thumb to support the blade 2 and cover the knife body 1 with the other four fingers. The other hand can use a screwdriver to turn the hexagon socket head screw 8 into the threaded hole 7. At this time, both hands of the staff are away from the knife body 1 and the blade 2, which can better prevent the staff from getting injured due to accidentally touching the blade 2 or using improper force when installing the blade 2, thereby improving safety during use.

[0030] When the blade 2 needs to be discarded, the staff holds the connecting rod 12 with one hand and covers the screwdriver with the other hand to remove the hexagon socket head screw 8. After the staff loosens the hexagon socket head screw 8, the blade 2 is still attached to the outer wall of the blade body 1 under the action of the plug block 3, rubber sheet 4, socket 5, and magnet 6, and will not fall suddenly due to loss of support, thereby reducing the possibility of the blade 2 falling suddenly and injuring the staff.

[0031] The height of the socket 5 is greater than the height of the insert block 3 , so that the insert block 3 can be conveniently moved inside the socket 5 when the height of the blade 2 needs to be adjusted up and down.

[0032] Furthermore, as a specific implementation of the utility model, the utility model provides a high-precision alloy soundboard gasket discarding milling cutter.

[0033] Specifically, Figure 1 and Figure 2 It is noted that the shape of the first through hole 10 is set to be an ellipse.

[0034] In the utility model, the shape of the first through hole 10 is set to be an ellipse. When cutting the alloy soundboard gasket, the installation height of the blade 2 is adjusted according to the diameter of the alloy soundboard gasket to be cut. The installed blade 2 is inclined. If the diameter of the alloy soundboard gasket to be cut is larger, the hexagon socket cylindrical head screw 8 is loosened a little, and the blade 2 is slid upward through the first through hole 10 for a certain distance. If the diameter of the alloy soundboard gasket to be cut is smaller, the blade 2 is slid downward through the first through hole 10 for a certain distance.

[0035] Furthermore, as another specific implementation of the utility model, the utility model provides a high-precision alloy soundboard gasket discarding milling cutter.

[0036] Specifically, Figure 1 and Figure 2 It is shown that an elastic washer 9 is provided on the outer wall of the hexagon socket head screw 8 , and the elastic washer 9 is provided on one side of the first through hole 10 .

[0037] In the utility model, the diameter of the elastic washer 9 is greater than the width of the first through hole 10, and the elastic washer 9 can be better stuck on one side of the first through hole 10. When the hexagon socket cylindrical head screw 8 is tightened, the elastic washer 9 will be compressed to form an elastic force, which will apply an outward force to the hexagon socket cylindrical head screw 8, thereby preventing the hexagon socket cylindrical head screw 8 from loosening under vibration or impact. At the same time, the elastic washer 9 can also expand the contact area between the hexagon socket cylindrical head screw 8 and the connected part, which helps to disperse the pressure and prevent the surface of the connected part from being damaged.

[0038] Furthermore, as another specific implementation of the utility model, the utility model provides a high-precision alloy soundboard gasket discarding milling cutter.

[0039] Specifically, Figure 1-Figure 3 It is shown that a drill bit 11 is inserted into the cutter body 1, a hexagon socket set screw 13 is threadedly connected to the cutter body 1, and a threaded through hole 14 matching the hexagon socket set screw 13 is formed on the drill bit 11 and the cutter body 1.

[0040] In the utility model, as the use time increases, the accuracy of the drill bit 11 may decrease, which may affect the quality of the processed workpiece. The drill bit 11 can be removed for grinding or replacement by rotating and unscrewing the hexagon socket set screw 13 with a screwdriver. Regular replacement of the drill bit 11 can ensure processing accuracy and efficiency.

[0041] Furthermore, as another specific implementation of the utility model, the utility model provides a high-precision alloy soundboard gasket discarding milling cutter.

[0042] Specifically, Figure 1-Figure 3It is shown that a connecting rod 12 is installed on the top of the blade body 1.

[0043] In the utility model, the connecting rod 12 can be installed on other parts. At the same time, when the staff uses a screwdriver to install the hexagon socket head screw 8, the connecting rod 12 provides a gripping point that allows the staff to more easily position the hexagon socket head screw 8, thereby simplifying the installation process and improving work efficiency. The staff's hands are away from the blade 2, which can reduce the safety risks caused by the staff's improper manual disassembly of the blade 2.

[0044] Furthermore, as another specific implementation of the utility model, the utility model provides a high-precision alloy soundboard gasket discarding milling cutter.

[0045] Specifically, Figure 1-Figure 4 It is shown that the material of the blade 2 is high-quality steel, and the material of the drill bit 11 is cemented carbide.

[0046] In the utility model, the high-quality steel has good toughness and wear resistance, and is suitable for cutting various types of materials. The high-quality steel has good cutting performance, and can provide high cutting accuracy and good surface quality for the alloy soundboard gasket. The alloy plate gasket cut by the high-quality steel blade 2 has a smooth edge without obvious flaws and defects. Cemented carbide is a very hard material with excellent wear resistance and impact resistance. The cemented carbide drill bit 11 is suitable for high-speed cutting and high-load applications.

[0047] Working principle: the staff holds the connecting rod 12 with one hand, and aligns the plug block 3 with the socket 5 on the blade body 1 with the other hand, and pushes the blade 2 to the direction of the blade body 1. The material of the blade 2 is high-quality steel, because steel is mainly composed of iron, and iron has good magnetic properties, so it is attracted by the magnet 6. The suction force of the magnet 6 on the blade 2 helps to push the plug block 3 to the inside of the socket 5. The rubber sheet 4 contacts the inner wall of the socket 5, which increases the friction, making it difficult for the plug block 3 to fall off from the inside of the socket 5. When the plug block 3, rubber sheet 4, socket 5, and magnet 6 are in contact, the plug block 3 is pushed to the inside of the socket 5. With mutual cooperation, the blade 2 can be better fixed on one side of the knife body 1. At this time, the staff only needs to hold the connecting rod 12 with one hand. There is no need for the staff to use the thumb to support the blade 2 and cover the knife body 1 with the other four fingers. The other hand can use a screwdriver to turn the hexagon socket head screw 8 into the threaded hole 7. At this time, both hands of the staff are away from the knife body 1 and the blade 2, which can better prevent the staff from getting injured due to accidentally touching the blade 2 or using improper force when installing the blade 2, thereby improving safety during use.

[0048] When the blade 2 needs to be discarded, the staff holds the connecting rod 12 with one hand and covers the screwdriver with the other hand to remove the hexagon socket head screw 8. After the staff loosens the hexagon socket head screw 8, the blade 2 is still attached to the outer wall of the blade body 1 under the action of the plug block 3, rubber sheet 4, socket 5, and magnet 6, and will not fall suddenly due to loss of support, thereby reducing the possibility of the blade 2 falling suddenly and injuring the staff.

[0049] The height of the socket 5 is greater than the height of the insert block 3 , so that the insert block 3 can be conveniently moved inside the socket 5 when the height of the blade 2 needs to be adjusted up and down.

[0050] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
