Abstract
The invention discloses a method for automatically detecting sand core assembly precision. The method comprises the following steps that a, a robot clamps a detection tool to measure the reference of sand core assembly; b, the robot clamps the detection tool to measure the characteristic points of sand core assembly; c, based on data measured by the step a and the step b and displacement data of the robot from the step a to the step b, position data of the characteristic points is calculated; and d, the position data is compared with theoretical data so as to determine whether the sand core assembly precision meets the requirement or not. The method for automatically detecting sand core assembly precision firstly measures the reference of sand core assembly and then measures the characteristic points of sand core assembly, so that influences of position deviation on measurement results when the sand core characteristic points reach detection stations are prevented, and the accuracy of detection results is improved.
Description
Technical field
The present invention relates to a kind of detection method of core assembly precision, particularly a kind of method of automatic detection core assembly precision.
Background technology
Core assembly precision is the key of Foundry Production, assembles not good general and directly causes casting dimension accuracy decline even to be scrapped.Therefore, the detection of core assembly precision is very important operation.
Due to core material and the singularity of formation method, casting dimension accuracy standards system, it is that artificial model goes contrast that traditional core assembly precision detects, and this control methods exists the problems such as not energetic, artificial judgement, inefficiency; Comparatively accurate detecting method is that operating personnel take height gauge, pit gauge goes to detect, but efficiency is lower like this.Along with the raising of automatization level, high-end casting sand core production line has realized full-automatic assembly line operation, needs corresponding fully-automated synthesis method to monitor the assembly precision of core.
The repeatable position precision of existing robot manipulation and the precision of digital gauge, can meet the measurement requirement of core assembly precision.But on streamline, when the core unique point detected arrives and detects station, its positional precision is also by the Accuracy of vehicle equipment, and the precision improving vehicle equipment will improve the cost of vehicle equipment greatly simultaneously.Therefore, need a kind of method of automatic detection core assembly precision, its can get rid of core unique point arrive detect station time position deviation on the impact of testing result, the cost of vehicle equipment need not be improved again.
The information being disclosed in this background technology part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Summary of the invention
The object of the present invention is to provide a kind of method of automatic detection core assembly precision, thus position deviation when overcoming core unique point arrival detection station in prior art is on the impact of testing result.
For achieving the above object, the invention provides a kind of method of automatic detection core assembly precision, the method comprises the steps:
A. robotic gripper's testing tool measures the benchmark of core assembling;
B. robotic gripper's testing tool measures the unique point of core assembling;
C. the displacement data from step a to step b based on the data measured by step a and step b and robot, calculates the position data of unique point; And
D. by position data compared with gross data, to judge whether core assembly precision meets the requirements.
Preferably, in technique scheme, judge in steps d whether core assembly precision meets the requirements and comprise: when the result of position data compared with gross data is in the margin tolerance allowed, clearance core assembles; And when the result of position data compared with gross data exceedes the margin tolerance of permission, give the alarm.
Preferably, in technique scheme, testing tool is digital gauge.
Compared with prior art, the present invention has following beneficial effect:
1. pass through the benchmark first measuring core assembling, then measure the unique point of core assembling, thus position deviation when avoiding core unique point arrival detection station is on the impact of testing result, improves the accuracy of testing result;
2. due to the precision without the need to improving vehicle equipment for this reason, so reduce overall cost;
3., by robot and digital gauge, realizing the automatic on-line monitoring of core assembly precision, when detecting that underproof core assembles, giving the alarm, to treat artificial treatment.
