Numerical control drilling machine having workpiece reinforcing function and high drilling precision

Abstract

The invention relates to a numerical control drilling machine having the workpiece reinforcing function and high drilling precision. The drilling machine comprises a base, a support, a drill bit and apower device, and further comprises a positioning mechanism and a fixing mechanism. The positioning mechanism comprises a connecting head, a supporting disc, a supporting ring, a limiting plate and at least two connecting assemblies, the fixing mechanism comprises a columnar concave opening, a piston block, a second spring, and at least two fixing assemblies, each connecting assembly comprises afixed casing pipe, a connecting rod and a first spring, and each fixing assembly comprises a seal cylinder, a piston rod and an oil conveying pipe. According to the numerical control drilling machinehaving the workpiece reinforcing function and high drilling precision, through the positioning mechanism, a workpiece can be positioned, the drill bit and the drilling face of the workpiece keep vertical, the punching precision of the numerical control drilling machine can be improved, through the fixing mechanism, the workpiece can be fixed, the slipping possibility of the workpiece can be reduced, and the punching precision of the numerical control drilling machine can be further improved.

Description

technical field [0001] The invention relates to the field of numerical control equipment, in particular to a numerical control drilling machine with a workpiece reinforcement function and high drilling precision. Background technique [0002] CNC machine tools are mainly used for cutting the inner and outer cylindrical surfaces of shaft parts or disk parts, the inner and outer conical surfaces of any cone angle, the complex rotary inner and outer curved surfaces, cylinders, and conical threads, etc., and can perform grooving, drilling, reaming, Reaming and boring etc. The CNC machine tool automatically processes the processed parts according to the pre-programmed processing program. We write the processing route, process parameters, tool trajectory, displacement, cutting parameters and auxiliary functions of the parts into a processing program sheet according to the instruction code and program format specified by the CNC machine tool, and then record the contents of the pr...

AI Technical Summary

Problems solved by technology

[0003] CNC drilling machine is a kind of CNC machine tool. When drilling plate workpieces, if the drilling surface of the workpiece is not perpendicular to the drill bit, it will cause the end of the drill bit close to the workpiece to slide, which reduces the drilling accuracy of the CNC drilling machine. , Not only that, when the CNC drilling machine of the prior art is drilling, if the workpiece is fixed unstable, it will cause the workpiece to slip, which further reduces the drilling accuracy of the CNC drilling machine
