[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-3 As shown, a tool processing clamping device includes a main board 1. A clamping component is installed on the top side of the main board 1. The clamping component includes an installation cavity 2. A servo motor 3 is installed inside the bottom side of the installation cavity 2. The output end of the servo motor 3 is installed with a turntable 4. Three arc grooves 5 are equidistantly opened inside the turntable 4. A slide bar 6 is slidably installed inside the arc groove 5. Three chutes 7 are equidistantly opened inside the top side of the installation cavity 2. A slider 8 is slidably installed inside the chute 7. One end of the slide bar 6 is fixedly installed on the bottom side of the slider 8. A clamping block 9 is installed on the top side of the slider 8. A groove 10 is opened inside the clamping block 9. An electrode plate 11 is installed on one side inside the groove 10. A movable rod 12 is slidably installed through the clamping block 9. One end of the movable rod 12 extends into the groove 10 and is equipped with an electrode piece 13. A tension spring 14 is fixedly connected between the electrode piece 13 and the groove 10. The tension spring 14 is sleeved on the outer wall of the movable rod 12;

[0023] A support plate 15 is fixed at the top side edge of the main board 1. A driving motor 16 is installed on one side of the support plate 15, and the output end of the driving motor 16 is fixedly connected to one side of the installation cavity 2. A warning lamp 26 is installed at the top side edge of the main board 1, and a control panel 27 is installed on one side of the main board 1. During operation, in practical applications, since the radii of cutters with different sizes are different, but in the prior art, only cutters with specific sizes can be clamped, which may cause the cutter to be clamped too tightly or too loosely, damaging the cutter or affecting the processing quality. When a cutter needs to be clamped, the servo motor 3 is started through the control panel 27. The servo motor 3 drives the turntable 4 to rotate, causing the slide bar 6 to slide in the arc-shaped groove 5. At the same time, the slider 8 slides in the chute 7, thereby driving the clamping block 9 to move closer to the center or disperse outward. When the clamping block 9 moves closer, the movable rod 12 is subjected to the extrusion force of the cutter and slides into the interior of the groove 10, stretching the tension spring 14, causing the electrode plate 11 and the electrode piece 13 to come into contact with each other and generate an electrical signal. The control panel 27 will control the warning lamp 26 to go out, indicating that the cutter is successfully clamped. If the warning lamp 26 lights up during the grinding process, it means that the electrode plate 11 and the electrode piece 13 are separated and the cutter clamping is unstable, reminding the operator to handle it. It realizes the fixation of cutters with different sizes and can avoid the phenomenon of excessive or loose clamping, reducing the possibility of damage to the cutter and improving the processing quality of the cutter. At the same time, when performing the grinding operation, the driving motor 16 is started, and its output end drives the installation cavity 2 to rotate, thereby being able to drive the cutter to rotate, realizing the comprehensiveness of cutter grinding.

[0024] Please refer to Figure 1 、 4 As shown in the figure, an L-shaped plate 17 is fixed at one end edge of the main board 1. A cylinder 18 is installed on the top side of the L-shaped plate 17, and the acting end of the cylinder 18 penetrates through the L-shaped plate 17 and is equipped with a buffer assembly.

[0025] The buffer assembly includes a sleeve 19. The sleeve 19 is fixed to the bottom side of the acting end of the cylinder 18. A buffer spring 20 is fixedly connected inside the sleeve 19. One end of the buffer spring 20 is fixedly connected to a connecting rod 21. One end of the connecting rod 21 slides through the outside of the sleeve 19 and is equipped with a grinding assembly.

[0026] The grinding assembly includes a mounting frame 22 which is fixed to the bottom side of the connecting rod 21. A rotating shaft 23 is rotatably mounted between the two sides inside the mounting frame 22. A grinding brush 24 is mounted on the outer wall of the rotating shaft 23. A grinding motor 25 is mounted on one side of the mounting frame 22. One end of the rotating shaft 23 is cooperatively connected to the output end of the grinding motor 25. During operation, in the production process of the tool, after turning operation, in order to make the surface of the tool smoother, grinding operation is required. When the tool needs to be ground, the cylinder 18 is started through the control panel 27. The cylinder 18 drives the buffer assembly and the grinding assembly to move downward above the tool. The buffer spring 20 in the buffer assembly plays a buffering role in cooperation with the damper, reducing the impact when the cylinder 18 operates, thereby avoiding over-grinding of the tool. When the cylinder 18 drives the grinding assembly to a proper position, the grinding motor 25 is started through the control panel 27. The grinding motor 25 drives the rotating shaft 23 to rotate, and then drives the grinding brush 24 to rotate at a high speed to grind the tool.

[0027] Working principle: When the tool needs to be clamped, the servo motor 3 is started through the control panel 27. The servo motor 3 drives the turntable 4 to rotate, causing the slide rod 6 to slide in the arc-shaped groove 5. At the same time, the slider 8 slides in the chute 7, thereby driving the clamping block 9 to move closer to the center or disperse outward. When the clamping block 9 moves closer, the movable rod 12 is subjected to the extrusion force of the tool and slides into the inside of the groove 10, stretching the tension spring 14, so that the electrode plate 11 and the electrode piece 13 come into contact with each other and generate an electrical signal. The control panel 27 will control the warning light 26 to go out, indicating that the tool is clamped successfully. If the warning light 26 lights up during the grinding process, it means that the electrode plate 11 and the electrode piece 13 are separated and the tool clamping is unstable, reminding the operator to deal with it. It realizes the fixation of tools of different sizes and can avoid the phenomena of over-clamping or under-clamping, reducing the possibility of damage to the tool and improving the processing quality of the tool. At the same time, when performing the grinding operation, by starting the driving motor 16, its output end drives the mounting cavity 2 to rotate, and then can drive the tool to rotate, realizing the comprehensiveness of tool grinding;

[0028] When the tool needs to be ground, the cylinder 18 is started through the control panel 27. The cylinder 18 drives the buffer assembly and the grinding assembly to move downward above the tool. The buffer spring 20 in the buffer assembly plays a buffering role in cooperation with the damper, reducing the impact when the cylinder 18 operates, thereby avoiding over-grinding of the tool. When the cylinder 18 drives the grinding assembly to a proper position, the grinding motor 25 is started through the control panel 27. The grinding motor 25 drives the rotating shaft 23 to rotate, and then drives the grinding brush 24 to rotate at a high speed to grind the tool.
