Description

Electrode intelligent detection system

Technical field

The present invention relates to a kind of processing mode of electrosparking, especially the electrode intelligent detection system of electrosparking.

Background technology

Electrosparking is a kind of processing mode of uniqueness, is good at processing line face, the position of bone, superhard material etc., therefore has important position in the mould manufacturing.As everyone knows, electrosparking needs electrode as consumable material, and the quality of electrode directly has influence on the quality of mould, therefore electrode is detected, and can guarantee the operation accurately and reliably of electrosparking, obtains good processing effect.

Common electrode detection method:

1. under the mode of learning of three-dimensional coordinates measurement, earlier manual measurement one time allows three-dimensional remember the manual measurement process, realizes measuring automatically when duplicate measurements.Shortcoming: it is longer to take time during the manual measurement first pass, and requires survey crew to have certain measurement experience and technical ability, is suitable for part in batches.

2. in the software systems of three coordinate measuring machine, show former CAD mathematical model, determine the measured point according to visual means from figure again, obtain X, Y, Z coordinate figure and the normal vector of measured point, the automatic process of measurement of regeneration with graphics mode.Shortcoming: measure and determine at that time to take the three-dimensional time in the measured point in three-dimensional software, three-dimensional can not be fully used, and requires survey crew to have certain technical ability.

Traditional detecting electrode method makes by hand purely and detects, and efficient is extremely low, even used three coordinate measuring machine, also fails to obtain good benefit.

Nowadays, market has proposed efficient fast mould, and this just requires the process-cycle short, and employed electrode has into hundred more than in the mold, therefore is necessary to carry out measuring machine and erowa positioning and clamping system are combined, and creates a cover intelligent checking system.

Summary of the invention

In order to reduce personnel's participation, improve electrode detection quality and speed, guarantee the security and the reliability of electrosparking, lower the labour intensity of electrode detection simultaneously, the invention provides a kind of electrode intelligent detection system

The technical solution adopted for the present invention to solve the technical problems is: a kind of electrode intelligent detection system comprises following content:

The generation of dot file: with UG software electrode is got a little when writing electrode processing program, obtained coordinate figure a little, the normal direction of some place face reaches the angle with respect to coordinate, these data is generated a .dat file automatically leave on the LAN (Local Area Network) automatically;

The generation of program external file: write a sequence number file of giving the measurement point sequence number, a system path file of depositing measurement report, a difference of giving direction of measurement, rotation of coordinate angle, calculation level measured value and the theoretical value of measurement point according to the dot file data obtains the measurement subroutine of spark value, and eccentricity value with the electrode measured compensates to the coordinate biasing file in the coordinate;

Some parameters of electrode measurement program: a. definition gauge head, measurement pattern, approaching distance, rollback distance etc.; B. read in Z coordinate bias, read in dot file; C. get reference field, obtain the electrode height value; D. read in sequential file and give the measurement point sequence number; E. read in coordinate biasing file, read in the measurement subroutine; F. measuring basis limit 4 points calculate the XY eccentricity value, the compensation eccentricity value; G. measure the spark value of all the other points and calculation level; H. finish all point measurements, gauge head is moved to home; I. store and report under the specified path.

The present invention has following advantage:

1) minimizing personnel's participation improves electrode detection quality and speed, guarantees the security and the reliability of electrosparking;

2) lowered the labour intensity of electrode detection greatly;

3) reduced the technical ability requirement, a new hand as long as train slightly, just can independently finish electrode measurement work.
