Abstract

The invention provides an electrode reference measurement method. Relocation of the electrode reference in the actual machining process on site is simplified by fully utilizing the relocation accuracy of an EROWA jig, the reference measurement workload is reduced, the on-site operation time is shortened, the working efficiency is improved, and meanwhile the error rate of measurement location is reduced. The electrode reference measurement method is characterized by including the following steps that first, an electrode blank is loaded into the EROWA jig; second, the electrode blank loaded into the EROWA jig is machined, and uniform center reference location is performed through a fixed EROWA base; third, the machined electrode and the EROWA jig are jointly installed in a machining center to be machined through electric pulses, and machining in the center of the fixed EROWA base is reference machining.

Description

A kind of electrode benchmark assay method

Technical field

The present invention relates to the technical field of machine tools, be specially a kind of electrode benchmark assay method.

Background technology

Work in-process adopts electric pulse to carry out part in the heart to add man-hour, electrode is arranged on EROWA tool, enter in machining center and process, EROWA tool will carry out electrode benchmark mensuration in the heart together with electrode work in-process, see Fig. 1, existing electrode benchmark assay method, when each machined electrode, electrode blank is arranged on EROWA fixture, machining center department ball woll base center is benchmark machined electrode, electrode processes after check to electric pulse department, electrode is loaded onto after electric pulse board, on board, again by electrode drawing benchmark, catch electrode reference coordinate, in above all processes, to measure altogether three times, for the first time for grabbing rough benchmark before the processing of machining center department, measuring basis during for the second time for check, for on electric pulse board, grab electrode benchmark for the third time, the each electrode benchmark of the method difference, benchmark difference between all departments, cannot be general, repeatedly duplicate measurements location, waste time and energy, increase the probability of makeing mistakes.

Summary of the invention

For the problems referred to above, the invention provides a kind of electrode benchmark assay method, by making full use of the reorientation precision of EROWA tool, simplify the on-the-spot actual electrode base weight location that adds man-hour, reduce benchmark and measure workload, shorten the execute-in-place time, increase work efficiency, reduced the error rate of measurement and positioning simultaneously.

Its technical scheme is such: a kind of electrode benchmark assay method, is characterized in that: it comprises the following steps:

(1), electrode blank packs in EROWA fixture;

(2), the electrode blank packing in EROWA fixture is carried out to electrode processing, origin reference location centered by fixing EROWA base is unified;

(3), the electrode processing is arranged on and on electric pulse lathe, carries out electric pulse processing together with EROWA fixture, fixing EROWA base center is benchmark processing.

In said method of the present invention, because electrode adds the EROWA base center machined electrode of man-hour to fix at blank, at electrode pair part, carry out pulse and add the also EROWA base center to fix in man-hour, realized the unification of electrode processing and part pulse machining center benchmark, by making full use of the reorientation precision of EROWA tool, simplify the on-the-spot actual electrode base weight location that adds man-hour, reduce benchmark and measure workload, shorten the execute-in-place time, increase work efficiency, reduced the error rate of measurement and positioning simultaneously.

The specific embodiment

See Fig. 1, a kind of electrode benchmark assay method, is characterized in that: it comprises the following steps:

(1), electrode blank packs in EROWA fixture;

(2), the electrode blank packing in EROWA fixture is carried out to electrode processing, origin reference location centered by fixing EROWA base is unified;

(3), the electrode processing is arranged on and on electric pulse lathe, carries out electric pulse processing together with EROWA fixture, fixing EROWA base center is benchmark processing.

Before processing starts, when electrode blank packs EROWA fixture into, roughly pack it into fixture center (do not need very accurate, as long as be as the criterion can process electrode shape).And machining center directly fixes on EROWA base center (must be very accurate, this is later machining benchmark, must repeated measurement have a fling at, but need not grab benchmark after after once completing again) by the benchmark of processing.The electrode benchmark of making like this, all at EROWA center, need not grab benchmark, and machining center also need only be grabbed this time benchmark when check and electric pulse detect and use electrode again, and later all electrode benchmark all need not be grabbed.

Above all processes need only accurately be located once before processing, the each electrode of positioning precision that later makes full use of EROWA fixture can be unified benchmark, once (quite easy) of coarse positioning when electrode blank is installed, electrode need not be grabbed benchmark again, and electrode benchmark need not heavily be grabbed by all departments.Only need periodic review, check and change the EROWA fixture that has damage, without resetting.

When electrode need to be revised, electrode is revised together with EROWA fixture entirety, and because center reference is unified, revised electrode is directly put into and on electric pulse lathe, carried out part pulse processing together with EROWA fixture, do not need to readjust positioning datum, greatly improved production efficiency.

Originally improve one's methods and mainly contain following advantage:

1. one-time positioning, is used for a long time, need not the duplication of labour;

2. save the operation of multiple departments, time saving and energy saving, increase work efficiency;

3. all electrodes are unified benchmark, convenient detection and correction electrode;

4. avoid people for grabbing fiducial error, reduce the probability of makeing mistakes, improve accuracy rate.
