Technical Field

[0001] The utility model relates to the technical field of drilling and tapping machines, in particular to a precision drilling and tapping machine. Background Art

[0002] A precision drilling and tapping machine is a high-precision metal cutting machine tool and a numerical control machine tool processing equipment. Due to the rapid changes in the 3C field, the drilling and tapping machine has gradually evolved into a composite processing machine tool that can process various complex curved surface models, complex concave molds, and profiling surfaces with high efficiency, high precision, and high reliability.

[0029] The frame 10 is the basic structure of the entire device and is used to support and fix other components. The fixed seat 20 is movably arranged on the frame 10 and is mainly used to place the workpiece to be processed. Its design adopts a six-point support structure for the large-span base, which is solid and stable, and can ensure no vibration and deformation during high-speed displacement.

It consists of precision ball screws for the X, Y, and Z axes, and precision linear guides for the three axes. The main shaft adopts a precision-class main shaft. The hydraulic cylinder makes the piston move up and down in the cylinder through the pressure provided by the hydraulic pump, thereby driving the lifting device to move up and down, and further controlling the lifting of the drill bit 40. The drill bit 40 is arranged on the three-axis linear platform 30 and corresponds to the fixed seat 20. It is mainly responsible for operations such as drilling and tapping the workpiece to be processed. When the drill bit 40 needs to be replaced, it can be removed by using a standard wedge iron or loosened with a drill chuck wrench. Through such a setting, the precision drilling and tapping machine 100 realizes high-precision and high-efficiency drilling through the precise motion control of the three-axis linear platform 30, in cooperation with a high-efficiency spindle motor and a precision drill bit 40. At the same time, since a hydraulic system is used to drive the movement of the three-axis linear platform 30, the machine has good rigidity and stability, greatly improving the precision and efficiency of the processing process.

[0030] In some embodiments, a moving component 50 is arranged at the bottom of the fixed seat 20. The moving component 50 includes a first slide rail 52 and a first slider 51.
