Abstract

The invention provides a hole making device which comprises a cutting tool main motion mechanism, a cutting tool feeding mechanism, a pressing mechanism, a positioning mechanism and a machine halt sensing mechanism. Through the hole making device, the hole making depth can be precisely controlled through precise calibration in the axial distance, the positioning mechanism and the machine halt sensing mechanism, and therefore highly precise control over the hole making depth is achieved, and complexity of a control and detection system is lowered. Integrated design of the whole hole making device is achieved, so that the number of the component parts of the whole hole making device is easily decreased, factors influencing the hole making precision are reduced, and therefore precise control over the hole making depth is improved; moreover, structural compactness, strength and rigidity of the whole hole making device are improved.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a hole-making device. Background technique [0002] With the continuous development of robot technology and machine tool industry, the hole-making equipment composed of special hole-making electric spindle unit and robot or machine tool body has been more and more widely used in the field of machinery, especially in the field of aerospace. Among them, process parameters such as motorized spindle speed, feed rate, tool parameters and cooling methods have a direct impact on the hole making accuracy. In the manufacturing process of aircraft, there are a large number of drilling tasks, and the precise control of the drilling depth is extremely demanding. At present, although high-precision servo systems, ball screws and linear guides can be used to achieve high-precision feeding, it is still difficult to determine and detect the starting point of hole making. problem. Cont...
