Description

technical field

[0001] The invention relates to the field of high-precision numerical control engraving, in particular to a multi-station numerical control engraving tool setting device. Background technique

[0002] At present, CNC mechanical engraving machines are widely used in various industries. Ordinary CNC engraving machines only have one engraving head, which can engrave various characters, curves and patterns on cylindrical surfaces, conical surfaces, and planes. The cost of a single CNC engraving machine is high, and the processing efficiency is not high. Using multi-station engraving heads and multi-station fixtures can achieve the efficiency of 5-8 sets of CNC engraving at the cost of one engraving machine. Existing such multi-station CNC engraving machine at present, but this engraving machine can only solve the multi-head engraving problem on the same plane. If the workpieces are not on the same plane, the engraving will appear in different shades, and the qu...

Embodiment Construction

[0023] The multi-station CNC engraving tool setting device provided by the present invention is composed of a control system and an electric contact signal detection system. As shown in Figures 1 to 5: the control system includes four circuits: a single-chip microcomputer control group, signal input conversion, and signal output conversion. The single-chip microcomputer control group circuit is composed of multiple independent single-chip microcomputer U4 and its peripheral circuits. It transmits the signal input conversion circuit from the numerical control system command and then sends the Z-axis pulse through the signal output conversion circuit to realize the multi-axis distribution of the numerical control command. , control multiple engraving heads 3 to feed the tool uniformly according to the command program, and perform automatic feed and tool setting of each axis and return to complete the tool setting signal according to the requirements of the CNC system command. The...
