Batch measurement method and measurement control system

Abstract

The invention provides a batch measurement method and a measurement control system, and belongs to the technical field of measurement. The batch measurement method comprises the following steps: receiving a product measurement order, wherein the product measurement order comprises product model data of a target product, model data of a measurement positioning bracket and each to-be-measured feature of the target product; setting the measurement parameter of each to-be-measured feature by using a preset method; grouping all the to-be-detected features according to a plane direction so that all the to-be-detected features in the same plane are divided into the same group; planning a measurement path according to the group information of the to-be-measured features, the measurement parameters, the target product and the shape features of the measurement positioning support; and driving the measurement equipment to execute measurement work according to the planned measurement path. According to the batch measurement method and the measurement control system, the accuracy and efficiency of automatic measurement can be improved.

Description

technical field [0001] The invention belongs to the field of measurement technology, in particular to a batch measurement method and a measurement control system. Background technique [0002] The measurement program needs to be compiled before the measurement of the parts, and the measurement equipment drives the measurement equipment to perform the measurement work according to the path compiled by the measurement program, so as to achieve the goal of knowing whether the size of the parts is qualified. [0003] At present, there are the following two measurement programming schemes: the first one, the automatic path planning function programming of the software, has the following weaknesses: 1) There are too many and irregular probe angles, and a large number of calibration probes are required to affect the measurement efficiency. 2) There will be a lot of collision points, and it takes about 10 hours to debug the collision, which affects the programming efficiency. 3) It...

Problems solved by technology

[0003] At present, there are the following two measurement programming schemes: the first one, the automatic path planning function programming of the software, has the following weaknesses: 1) There are too many and irregular probe angles, and a large number of calibration probes are required to affect the measurement efficiency

2) There will be a lot of collision points, and it takes about 10 hours to debug the collision, which affects the programming efficiency

3) It is necessary to manually adjust the measurement parameters of various characteristics, and the efficiency is relatively low

The second method is to manually add the program sequence point by point to plan the path and debug it to program. It has the following weaknesses: 1) Manually add the program sequence point by point and plan the path is inefficient. Usually, it takes about 16 hours to program a body-in-white, and the efficiency is relatively low.

2) Manual point selection is easy to make mistakes, which affects programming efficiency. Traditional car manufacturing methods have complex and changeable sizing processes, few standards to follow for sizing work, sizing knowledge depends on experience, and problem solving is done after the fact.

The above reasons make it difficult for traditional size solutions to meet the requirements of modern car manufacturing, so it is urgent to design an efficient solution to size problems

3) It is necessary to manually adjust the measurement parameters of various characteristics, and the efficiency is relatively low
