AI Technical Summary
The frame structure of traditional CNC drilling machines leads to unstable drilling, loose bolts, and equipment instability. In addition, the power head is large and difficult to install in a narrow space, making it impossible to shift gears of the mechanical spindle and meet diverse processing needs.
The drive motor is embedded in the slide box. The drive assembly drives the shift assembly and drive shaft sleeve to rotate, thereby realizing the rotation of the tool holder and the gear adjustment. Combined with the grating ruler and photoelectric sensor to monitor the position of the tool holder, the device structure is optimized to adapt to the installation and processing needs of different scenarios.
The device size has been reduced, the installation flexibility of the equipment has been improved, the tool holder shifting function has been realized, the processing stability and equipment safety have been enhanced, and diverse processing needs have been met.
