Good blade fixing ensures that the blade always stays in the correct position during machine operation, effectively avoiding danger. The structure also ensures convenient and quick blade replacement, improving the safety and reliability of the equipment during use, thus solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A blade fixing device for a cutting machine includes a cutting blade protective cover left fixedly installed on the left side of the base of the cutting machine. Two symmetrical grinding disc clamps are fixedly connected to one side of the cutting blade protective cover left. A blade is rotatably connected to the opposite side of the two grinding disc clamps. Four mounting posts are provided through the surfaces of the grinding disc clamps and the blade. One end of the four mounting posts is tightly fitted to the cutting blade protective cover left. The four mounting posts are rotatably connected to the blade. A connecting plate is fixedly connected to the right side of the four mounting posts. A side baffle is fixedly connected to the central axis on the right side of the connecting plate. A mounting block is fixedly connected to the right side of the side baffle. A cutting blade protective cover right is provided on the right side of the cutting blade protective cover left. An L-shaped plate is fixedly connected to the left side of the inner cavity of the cutting blade protective cover right. Two symmetrical fixing shells are fixedly connected to the front side of the inner side of the L-shaped plate. Clamping members are provided on the opposite side of the two fixing shells. The mounting block is adapted to the two clamping members.

[0006] Preferably, the top and bottom of the two inner cavities of the fixed shell are fixedly connected to connecting sleeves, and the inner cavity of the connecting sleeve is slidably connected to a sliding rod, which is fixedly connected to the clamping member.

[0007] Preferably, a spring is fitted onto the surface of the connecting sleeve and the sliding rod, and the two ends of the spring are welded to the fixed shell and the clamping member, respectively.

[0010] Preferably, the surfaces of the grinding disc clamp and the blade are provided with circular holes for the mounting posts to pass through, the blade is rotatably connected to the surfaces of the four mounting posts, and the left and right cutting disc protective covers are tightly fitted together.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model uses the cooperation of mounting column, connecting plate and side baffle to limit the grinding disc clamping plate and blade. Then, through the cooperation of connecting sleeve, sliding rod and clamping part, the clamping part is tightly locked with the cutting disc protective cover, thereby fixing the blade at the top of the cutting machine base. This achieves the purpose of using blade clamping and fixing structure. The fixed blade can be used for fine grooving, drilling and other operations on these fine materials, avoiding damage to the material due to blade shaking, achieving high-quality fine cutting. Good blade fixing can ensure that the blade is always kept in the correct position during machine operation, effectively avoiding danger. The structure ensures convenient and quick blade replacement, improving the safety and reliability of the equipment during use.

[0013] 2. By using the connecting sleeve and the sliding rod together, the connecting sleeve acts as a fiber to the sliding rod when it slides in the inner cavity of the connecting sleeve, ensuring that the clamping part will not deviate when the sliding rod drives the clamping part to move, thus improving the stability of the clamping part during use.

[0014] 3. The present invention uses a spring to provide a continuous and stable clamping force. Even after long-term use or after being subjected to a certain degree of external force interference, the elasticity of the spring can still ensure the clamping state of the clamping component on the mounting block, which helps to prevent the clamping component from falling off due to loosening and improves the reliability and stability of the product.

[0015] 4. This utility model uses the combination of bolts and nuts. Tightening the nuts can generate axial tension in the bolts, thereby tightly fitting the left and right surfaces of the cutting blade protective cover together. This fastening force can effectively prevent relative displacement between the left and right cutting blade protective covers during vibration, impact, or normal use. The tightening of the bolts and nuts ensures that the outer shell remains tightly connected even when the cutting machine vibrates at high speed, preventing loosening and ensuring the normal operation of the blade.

Detailed Implementation

[0024] In the following description, embodiments of the blade fixing device for a cutting machine according to the present invention will be described with reference to the accompanying drawings.

[0025] Figure 1-5This invention illustrates a blade fixing device for a cutting machine according to an embodiment of the present invention. It includes a cutting blade protective cover left 2 fixedly installed on the left side of the cutting machine base 1. Two symmetrical grinding disc clamps 3 are fixedly connected to one side of the cutting blade protective cover left 2. A blade 4 is rotatably connected to the opposite side of the two grinding disc clamps 3. Four mounting posts 5 are provided through the surfaces of the grinding disc clamps 3 and the blade 4. One end of each mounting post 5 is tightly fitted to the cutting blade protective cover left 2. The four mounting posts 5 are rotatably connected to the blade 4. A connecting plate 6 is fixedly connected to the right side of the four mounting posts 5. A side baffle 7 is fixedly connected to the central axis on the right side of the connecting plate 6. A mounting block 8 is fixedly connected to the right side of the side baffle 7. A cutting blade protective cover right 9 is provided on the right side of the cutting blade protective cover left 2. An L-shaped plate 10 is fixedly connected to the left side of the inner cavity of the right 9. Two symmetrical fixed shells 11 are fixedly connected to the front side of the inner side of the L-shaped plate 10. Connecting sleeves 12 are fixedly connected to the top and bottom of the inner cavities of the two fixed shells 11. A sliding rod 13 is slidably connected to the inner cavity of the connecting sleeve 12. The sliding rod 13 is fixedly connected to the clamping member 15. Through the cooperation of the connecting sleeve 12 and the sliding rod 13, the connecting sleeve 12 acts as a support for the sliding rod 13 when the sliding rod 13 slides in the inner cavity of the connecting sleeve 12, ensuring that the clamping member 15 will not deviate when the sliding rod 13 drives the clamping member 15 to move, thus improving the stability of the clamping member 15 during use. Springs 14 are sleeved on the surfaces of the connecting sleeve 12 and the sliding rod 13. Welded to the fixed housing 11 and the clamping member 15 respectively, the spring 14 provides a continuous and stable clamping force. Even after long-term use or under certain external interference, the elasticity of the spring 14 can still ensure the clamping member 15 clamps the mounting block 8, helping to prevent the clamping member 15 from falling off due to loosening, thus improving the reliability and stability of the product. Clamping members 15 are provided on the opposite side of the two fixed housings 11. The mounting block 8 is adapted to the two clamping members 15. The top and rear of the left side of the cutting disc protective cover 2 are fixedly connected to the arc plate 16. The right side of the two arc plates 16 is provided with the arc plate 2, which is fixedly connected to the right side of the cutting disc protective cover 9. The top of the right side of the cutting disc protective cover 9 is provided with Multiple bolts 18 are used to fix the surface of the arc-shaped plate 17 to the arc-shaped plate 16. Nuts 19 are threaded onto the surface of the bolts 18, with one side of the nut 19 tightly fitted to the arc-shaped plate 16. Through the cooperation of the bolts 18 and nut 19, tightening the nut 19 generates axial tension in the bolts 18, thus tightly sealing the surfaces of the left and right cutting disc guards 2 and 9. This tightening force effectively prevents relative displacement of the left and right cutting disc guards 2 and 9 during vibration, impact, or normal use. The tightening of the bolts 18 and nut 19 ensures that the outer casing remains tightly connected even when the cutting machine vibrates at high speed, preventing loosening and guaranteeing the normal operation of the blade 4.Both the grinding disc clamp 3 and the blade 4 have circular holes on their surfaces for the mounting posts 5 to pass through. The blade 4 is rotatably connected to the surfaces of the four mounting posts 5, and the left and right cutting disc protective covers 2 and 9 are tightly fitted together.

[0026] Working Principle: When using this invention, the user removes the side baffle 7, which causes the mounting post 5 to penetrate into the inner cavity of the grinding disc clamping plate 3 and the blade 4. Since the left side of the mounting post 5 is tightly fitted with the right side of the inner cavity of the left side of the cutting disc protective cover 2, the mounting post 5 fixes the blade 4. Then, the user moves the right side of the cutting disc protective cover 9 to the right side of the left side of the cutting disc protective cover 2. This causes the right side of the cutting disc protective cover 9 to move the L-shaped plate 10 towards the side baffle 7, causing the L-shaped plate 10 to clamp the clamping member 15 on the upper and lower sides of the mounting block 8. Simultaneously, the two clamping members 15 cause the sliding rod 13 to slide within the inner cavity of the connecting sleeve 12. Due to the relative movement of the clamping members 15, the spring 14 elastically shortens on the surfaces of the connecting sleeve 12 and the sliding rod 13, thereby tightening the clamping mechanism. Part 15 will move from the top of the mounting block 8 into the arc-shaped grooves on the upper and lower sides of the mounting block 8. Then, the mounting block 8 will limit the clamping part 15, and the sliding rod 13 will slide to its original position in the inner cavity of the connecting sleeve 12, so that the left 2 and right 9 of the cutting disc protective cover will fit tightly together, and the arc plate 16 and arc plate 2 17 will also fit tightly together. The bolt 18 will pass through the surface of the arc plate 16 and arc plate 2 17, so that the nut 19 will rotate on the surface of the bolt 18. The nut 19 will fix the left 2 and right 9 of the cutting disc protective cover. Then, the two clamping parts 15 will not detach from the mounting block 8, so that the mounting post 5 will limit the blade 4. Finally, the blade 4 at the top of the cutting machine base 1 is fixed and will not shift or fall off during use.

[0027] In summary, this cutting machine uses a blade fixing device. Through the cooperation of the mounting column 5, connecting plate 6, and side baffle 7, the grinding disc clamp 3 and blade 4 are limited. Then, through the cooperation of the connecting sleeve 12, sliding rod 13, and clamping member 15, the clamping member 15 is tightly engaged with the cutting disc protective cover 9, thereby fixing the blade 4 at the top of the cutting machine base 1. This blade clamping and fixing structure allows for precise grooving and drilling operations on delicate materials, preventing damage due to blade movement and achieving high-quality precision cutting. Good blade fixing ensures the blade remains in the correct position during machine operation, effectively preventing accidents. The structure also ensures convenient and quick blade replacement, improving the safety and reliability of the equipment.
