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...

Abstract

The invention provides a tool setting device for multi-station numerical control engraving, which is composed of a control system and an electrical contact signal detecting system, wherein the control system comprises four circuits of a single chip computer control group circuit, a signal input and transformation circuit and a signal output and transformation circuit, the single chip computer control group circuit is composed of a plurality of independent single chip computers U4 and peripheral circuits thereof, the electrical contact signal detecting system is a good conductor composed of a body (7), a worktable, a clamp and a workpiece (4), and connected with the power supply via 'earth' connection, the positive electrode of the power supply is connected with an engraving head (3) which is connected with a main shaft motor (2). The invention can realize automatic tool setting, and enable all the tools to be positioned on the surface of the workpiece before engraving feed, particularly consistency of engraving depth is guaranteed in high precision engraving, further the performance is reliable and the breaking edge rate is smaller than 0.0001%. The device of the invention can be widely applied to precise engraving of numerical control engraving machines and multi-station processing systems of numerical control milling machines, machining centers and the like.

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...
