Carving head with feed motion

Abstract

The invention provides a carving head with feed movement, which consists of a carving head control system and an execution mechanical system, wherein, the carving head control system consists of a single chip system which depends on an electrical contact for tool setting; the execution mechanical system comprises the feed movement and a mechanism of high-speed rotating and cutting movement, which are integrated and realized in the manner of nesting. An input port of the single chip system receives signals of standard numerical control commands from a numerical control system; the signals are transformed into special control signals of a stepping motor after processed inside the single chip and then are outputted to the stepping motor through a command transforming interface, thereby realizing the separate control of feed movement of the carving head. Simultaneously, the tool setting process is realized by cycled detection of the signals of the electrical contact by the single chip system, and the numerical control system can be monitored in the whole process and can be removed at any time. The carving head with feed movement combines a movable feed mechanism and a principal axis with high-speed rotation in the manner of nesting, thereby decreasing the carving head size, overcoming the problem of limited space after the conventional principal axis is provided with a feed device, increasing the complete performance and production efficiency and guaranteeing the 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
