[0013] Please see Figure 1-7A cavity-assisted milling tool includes an outer shell, which is composed of a housing 1 and a connecting housing 2. A drive shaft 3 and a shaft body 4 are rotatably mounted on the housing 1 and the connecting housing 2, respectively. One end of the drive shaft 3 is connected to the power drive end of an external machine tool, and one end of the shaft body 4 is provided with a tool holder 5. A first synchronous pulley 6 and a second synchronous pulley 7 are respectively provided on the drive shaft 3 and the shaft body 4, and the first synchronous pulley 6 and the second synchronous pulley 7 are connected by a synchronous belt. A universal connecting plate 8 is provided on the housing 1, and the housing 1 is fixedly installed on the power drive end of the machine tool through the universal connecting plate 8. A clamping end that cooperates with the power drive end of the machine tool is installed on the upper end of the drive shaft 3. The housing 1 is the core load-bearing structure of the device's drive end. Internally, the drive shaft 3 is fixed by bearings, spacers, and pressure caps. A universal connecting plate 8 is also installed, providing an installation reference and protection for the drive shaft 3, synchronous pulley 6, and other components. Connecting housing 2 is spliced ​​with housing 1 to form a complete outer shell. One end of the connecting housing 2 uses a positioning inclined surface 9 in conjunction with upper and lower sliders 10 and 11 to achieve precise docking with housing 1. Internally, the shaft 4 is fixed by bearings, spacers, and pressure caps, providing an installation base for the protective cover 14. One end of the drive shaft 3 connects to the external machine tool's power drive end, and the upper end has a clamping end that rotates in conjunction with the machine tool's power drive end. Synchronous pulley 6 is installed on the shaft to transmit power, serving as the core for power input and transmission. The spindle assembly, with spindle body 4 as the core output spindle, has a tool holder 5 at one end for mounting tools. A second synchronous pulley 7 is mounted on the spindle to receive power transmitted by the synchronous belt, driving the tool to cut metal materials. The tool holder 5, mounted at one end of spindle body 4, is used to hold various cutting tools. Combined with a side-locked ER collet and collets of different diameters, it enables quick tool changes. A first synchronous pulley 6 is fixed to the drive shaft 3 and, in conjunction with the second synchronous pulley 7 via a synchronous belt, stably transmits power from the drive shaft 3 to the output end, ensuring synchronous power transmission. A universal connecting disc 8 is used to fix the housing 1 to the machine tool's power drive end, achieving a stable connection between the device and the machine tool and ensuring installation accuracy.

[0014] Please see Figure 6 and Figure 7 The connecting shell 2 is provided with multiple sets of positioning inclined surfaces 9 at one end connected to the housing 1. The connecting shell 2 is detachably provided with an upper slider 10 and a lower slider 11 that cooperate with the positioning inclined surfaces 9. The housing 1 is detachably provided with an upper pressure block 12 and a lower pressure block 13 that cooperate with the upper slider 10 and the lower slider 11. The connecting shell 2 is detachably provided with a protective cover 14. The upper slider 10 is detachably mounted on the connecting shell 2 and cooperates with the positioning inclined surface 9 and the upper pressure block 12 to achieve precise positioning and fixation of the connecting shell 2 and the shell 1, while also assisting in tightening the synchronous belt. The lower slider 11 is detachably mounted on the connecting shell 2 and cooperates with the positioning inclined surface 9 and the lower pressure block 13 to further enhance the connection stability between the connecting shell 2 and the shell 1, and works with the upper slider 10 to tighten the synchronous belt to ensure stable power transmission. The upper pressure block 12 is detachably mounted on the shell 1 and cooperates with the upper slider 10 to press and fix the upper connection between the connecting shell 2 and the shell 1, preventing displacement during transmission. The lower pressure block 13 is detachably mounted on the shell 1 and cooperates with the lower slider 11 to press and fix the lower connection between the connecting shell 2 and the shell 1, ensuring the stability of the overall structure. The protective cover 14 is detachably mounted on the connecting shell 2 to cover the synchronous belt and synchronous pulley transmission area, preventing foreign objects from entering the transmission process and affecting power transmission, while also protecting the safety of the operator.

[0015] Working principle: The device is fixedly installed on the machine tool's power drive end via the universal connecting plate 8 on the housing 1. The housing 1 and the connecting housing 2 are precisely spliced ​​and locked together via the positioning inclined surface 9, the upper slider 10, the lower slider 11, the upper pressure block 12, and the lower pressure block 13, forming a complete and stable outer shell protective structure. At the same time, the upper slider 10 and the lower slider 11 work together to tighten the synchronous belt, ensuring the foundation of power transmission. The clamping end at the upper end of the drive shaft 3 rotates in conjunction with the external machine tool's power drive end to receive the power output from the machine tool. The synchronous pulley 6 on the drive shaft 3 rotates synchronously with the drive shaft 3. Power is transmitted to the synchronous pulley 7 on the shaft 4 via a synchronous belt. Taking advantage of the synchronicity of the synchronous belt drive, stable power transmission is achieved from the drive end to the output end. The protective cover 14 on the connecting shell 2 covers the transmission area to avoid interference from foreign objects and personnel safety risks. The shaft 4 rotates under the drive of the synchronous pulley 7, which in turn drives the tool on the tool holder 5 to rotate at high speed, performing cutting processing on metal materials with a cavity depth of less than 1 meter. The entire operation process is consistent with the original machine tool operation, and the cutting parameters are displayed in real time on the system operation panel for easy and precise control.
