Carving head with feed motion

Abstract

The engraving head with feed movement provided by the present invention is composed of an engraving head control system and an executive mechanical system; the engraving head control system is composed of a single-chip microcomputer system that relies on electrical contact for knife setting, and the executive mechanical system includes feed movement and high-speed rotation The cutting motion mechanism is realized by the integration of the two. The input interface of the single-chip microcomputer system accepts the standard numerical control command signal of the numerical control system, which is converted into a special control signal for the stepping motor after the internal processing of the single-chip microcomputer, and then output to the stepping motor through the command conversion interface, realizing the independent feed motion control of the engraving head ;At the same time, the process of tool setting is realized by the single-chip microcomputer system for cyclic detection of the electrical contact signal, and the numerical control system can monitor the whole process and release it at any time. The invention nests and combines the feed moving mechanism and the high-speed rotating spindle, reduces the volume of the engraving head, overcomes the problem of limited space of the conventional spindle after adding the feed device, improves the overall performance and production efficiency, and ensures product quality.

Description

technical field [0001] The invention relates to the field of engraving, in particular to an engraving head with feeding movement. Background technique [0002] At present, the engraving heads produced by professional electric spindle manufacturers are generally used vertically and fixedly, and the price is relatively high. It is essentially a high-speed, high-rigidity and precise motor controlled by frequency conversion, mainly supported by precision rolling bearings, lubricated with grease, and cooled by external circulating water. [0003] The multi-spindle CNC engraving machine tools put on the market mostly adopt the gantry structure in the feed depth control, and some of them use the independent feed control of the engraving head. Due to the characteristics of the gantry structure itself, when the processing depth is controlled, it is easy to cause the skew of the gantry beam body, the control accuracy is not high, and the volume is large; at the same time, due to the ...

AI Technical Summary

Problems solved by technology

However, when the professional electric spindle realizes the engraving movement, since it has no moving feed device, when engraving various characters, curves and patterns on cylindrical surfaces, conical surfaces, and planes, it is necessary to add a feed movement mechanism. It will make the engraving head larger, and also increase the center height of the engraving head

The use in some multi-station occasions with limited space is limited

The increase of the center height will put forward higher requirements on the rigidity of the supporting column of the machine tool, which will increase the manufacturing cost of the machine tool, and also violate the principle of striving for lightness in the design of the CNC engraving machine
