When cutting the workpiece, the spindle box fixing frame 3 is first fixed to the designated fixing plate through the threaded holes on its surface, and then the output interface 404 is energized to start the electric cylinder 401. Then the electric cylinder 401 drives the internal fixed bracket 2 to move through the output rod 403, and then the internal fixed bracket The frame 2 drives the slider 405 to move up and down horizontally along the linear guide rail 402, and at the same time, the internal fixed bracket 2 drives the motor 5 to move up and down horizontally, and then the motor 5 drives the connecting shaft 6, the fixed column 8 and the cutting tool 10 to move horizontally, and then the cutting tool 10 contacts the surface of the workpiece, and the force of the cutting tool 10 contacting the surface of the workpiece is fed back to the sensor on the electric cylinder 401 through a signal, and then fed back to the system by the sensor to compare and confirm that it is consistent with the target cutting force. This cutting force can be set according to the on-site processing materials, width, blank conditions and other conditions, and the floating device 7 adds air with a fixed pressure to play a certain buffering role, which ensures that the tool is not easily damaged, and is used in conjunction with the electric cylinder 401 to ensure that the up and down adjustment torque error is guaranteed to be within a certain range, thereby further ensuring the processing error and the processing results are correct.

[0021] Furthermore, one side of the surface of the slider 405 is connected to the internal fixing bracket 2, and four groups of linear guide rails 402 are provided. Through the arrangement of the linear guide rails 402 and the slider 405, when in use, the linear guide rails 402 are used to guide the slider 405, so that the slider 405 can move along a specific straight line direction when in motion, and the slider 405 can drive the moving internal fixing bracket 2 to move horizontally along a straight line.

[0022] Furthermore, one end of the output rod 403 passes through the external fixed bracket 1 and is connected to the electric cylinder 401, and the electric cylinder 401 is electrically connected to the output interface 404. Through the setting of the electric cylinder 401, when in use, when the electric cylinder 401 is powered on and started, it can push the output rod 403 to move horizontally, thereby facilitating the subsequent output rod 403 to push the internal fixed bracket 2 to move.

[0023] Further, the mounting mechanism 9 includes an embedding groove 901, a pressure block 902, a limiting rod 903, a slot 904, a limiting groove 905, a spring 906 and a block 907. The surface of the fixed column 8 is provided with an embedding groove 901, the surface of the fixed column 8 is embedded with a pressure block 902, the interior of the fixed column 8 is connected with a limiting rod 903, the inner side of the cutting tool 10 is provided with a slot 904, one side of the surface of the pressure block 902 is provided with a limiting groove 905, one side of the surface of the pressure block 902 is connected with a spring 906, and one side of the surface of the pressure block 902 is connected with a block 907. By setting the embedding groove 901, the pressure block 902, the limiting rod 903, the slot 904, the limiting groove 905, the spring 906 and the block 907, when in use, When installing the cutting tool 10, first press the pressure block 902. Since the limiting groove 905 cooperates with the limiting rod 903, the pressure block 902 can move smoothly and squeeze the spring 906. The spring 906 is deformed under the force, and the clamping block 907 moves synchronously with the pressure block 902 until the clamping block 907 moves to a certain position, and one end of the cutting tool 10 is embedded in the inside of the embedding groove 901. Then release the pressure block 902, the spring 906 rebounds and drives the pressure block 902 and the clamping block 907 to reset, and one end of the clamping block 907 is clamped into the inside of the clamping groove 904. At this time, the installation of the cutting tool 10 is completed. When the cutting tool 10 needs to be disassembled, just press the pressure block 902 to take out the cutting tool 10 and replace it.

[0024] Furthermore, one end of the block 907 is consistent with the size of the slot 904, and one end of the spring 906 is connected to the inner wall of the fixed column 8. Through the arrangement of the spring 906 and the block 907, when in use, the block 907 is horizontally aligned with the slot 904, the pressure block 902 is released, and the rebound of the spring 906 can drive the pressure block 902 and the block 907 to reset, thereby facilitating the subsequent insertion of the block 907 into the slot 904.

[0025] Furthermore, one end of the limiting rod 903 is embedded in the limiting groove 905, and the embedding groove 901 matches the size of one end of the cutting tool 10. Through the setting of the limiting rod 903 and the limiting groove 905, when in use, the opened limiting groove 905 cooperates with the limiting rod 903. When the pressure block 902 is pressed, it can limit the moving direction of the pressure block 902, thereby enhancing the stability of the pressure block 902 when it moves.

[0026] Working principle: First, when installing the cutting tool 10, press the pressure block 902. Since the limiting groove 905 cooperates with the limiting rod 903, the pressure block 902 can move smoothly and squeeze the spring 906. The spring 906 is deformed under the force, and the clamping block 907 moves synchronously with the pressure block 902 until the clamping block 907 moves to a certain position, and one end of the cutting tool 10 is embedded in the inside of the embedding groove 901. Then release the pressure block 902, the spring 906 rebounds and drives the pressure block 902 and the clamping block 907 to reset, and one end of the clamping block 907 is clamped into the inside of the clamping groove 904. At this time, the installation of the cutting tool 10 is completed. When the cutting tool 10 needs to be disassembled, it is only necessary to press the pressure block 902 to take out and replace the cutting tool 10. Later, when cutting the workpiece, first fix the spindle box fixing frame 3 to the designated fixing plate through the threaded hole on its surface, and then energize the output interface 404 to start the electric cylinder 401. , then the electric cylinder 401 drives the internal fixed bracket 2 to move through the output rod 403, and then the internal fixed bracket 2 drives the slider 405 to move up and down horizontally along the linear guide rail 402, and at the same time the internal fixed bracket 2 drives the motor 5 to move up and down horizontally, and then the motor 5 drives the connecting shaft 6, the fixed column 8 and the cutting tool 10 to move horizontally, and then the cutting tool 10 contacts the surface of the workpiece, and the force of the cutting tool 10 contacting the surface of the workpiece is fed back to the sensor on the electric cylinder 401 through a signal, and then fed back to the system by the sensor, and compared and confirmed to be consistent with the target cutting force. This cutting force can be continuously changed and set according to the on-site processing materials, width, blank conditions and other conditions, and the floating device 7 is added with air of fixed pressure to play a certain buffering role, so as to ensure that the tool is not easily damaged, and is used in conjunction with the electric cylinder 401 to ensure that the up and down adjustment torque error is guaranteed to be within a certain range, thereby further ensuring the processing error and the processing result are correct.
