Benchmark integration processing method and multi-directional locating block thereof

Abstract

The invention discloses a benchmark integration processing method applied to a large numerical control planomilling machine and a multi-directional locating block thereof. In the invention, the multi-directional locating block provided with a plurality of locating elements, which is fixed on the large numerical control planomilling machine serves as a uniform benchmark of cutter calibration dead-center position in each processing step and the central points of the locating elements on the multi-directional locating block serve as the initial pint and the end point of the numerical control subprogram for controlling each processing step, the multi-directional locating block is composed of a datum body and a foundation, wherein the datum body is provided with a plurality of locating elements which comprise at least one locating plane and at least one locating circular orifice. In the invention, as the uniform benchmark is set, program control in the whole processing course is realized, manual operation is avoided, production efficiency and safety are enhanced, labor intensity and economic costs are lowered, safety and quality incidents are avoided, therefore the invention is especially suitable for processing large workpieces by the numerical control planomilling machine.

Description

Technical field: [0001] The invention relates to a mechanical processing method, in particular to a benchmark integrated processing method applied to a large numerically controlled gantry milling machine and a multi-directional positioning block thereof. Background technique: [0002] When processing a workpiece on a CNC machine tool, the trajectory program of the tool is usually programmed in advance, and then input into the control unit of the CNC machine tool, and then the machine tool and the tool are started to cut the workpiece. The same is true for workpieces processed by large CNC gantry milling machines. The existing processing methods are as follows: firstly, the workpiece cutting program is compiled, and the program is compiled into subroutines in units of each cutting step. Control the trajectory of a cutting tool from the beginning of cutting to the end of cutting; then input the programmed workpiece cutting program into the control part of the CNC gantry millin...

Problems solved by technology

[0010] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing large-scale CNC gantry milling machine processing methods, and provide a benchmark integrated processing method. By setting a unified tool calibration zero position reference, a systematic and coherent processing CNC program is compiled to realize processing. The program control of the whole process avoids the manual operation of tool setting, feeding and retracting, so as to ensure the safety of people and equipment, reduce process costs and labor intensity, and improve product quality and processing efficiency.
