Three-coordinate measuring system and method

Abstract

The invention provides a three-coordinate measuring system and a three-coordinate measuring method. The three-coordinate measuring system comprises three-coordinate measuring equipment and a to-be-measured product type acquisition device, wherein the three-coordinate measuring equipment is provided with a measuring head and a control component, the control component controls the motion of the measuring head by means of a measuring program preset according to product types, and the control component is electrically connected with the measuring head; the to-be-measured product type acquisition device comprises an optical acquisition head capable of scanning a graphic identifier; the optical acquisition head is electrically connected with the control component; and the control component obtains a product type of a to-be-measured product according to the graphic identifier scanned by means of the optical acquisition head, calls a corresponding measuring program to control the motion of themeasuring head, and measures and obtains measuring data of the to-be-measured product. The three-coordinate measuring system and the three-coordinate measuring method are convenient, precise and rapid through calling the measuring program by reading and identifying the graphic identifier, effectively prevents manmade errors and improve the detection efficiency.

Description

technical field [0001] The invention relates to product size measurement technology, in particular to a three-coordinate measurement system and method. Background technique [0002] The three-coordinate measuring machine is a dimension measuring device widely used in machinery, electronics, instrumentation, plastics and other industries. The measurement process is to obtain the measurement points of the measured object by placing the measured object in the measurement space of the three-coordinate measuring machine. Three-dimensional space coordinate position, according to the space coordinate value of these points, calculate the geometric size, shape and position of the measured object. Three-coordinate measuring machine is one of the most effective ways to measure and obtain dimensional data, because it can replace multiple surface measurement tools and expensive combination gauges, and reduce the time required for complex measurement tasks from hours to minutes, which is ...

Problems solved by technology

Due to the large output of the wheel hub and the heavy measurement workload, generally by presetting a variety of measurement programs in the three-coordinate measuring machine, each measurement program corresponds to a unique type of wheel hub made by a unique mold, and the corresponding program is directly called during measurement. The alignment of the workpiece improves the measurement speed; however, in the prior art, when the three-coordinate measuring machine calls the program, the operator needs to find and call it from the three-coordinate measuring machine according to the type of the hub and the mold.

Due to the many types of hubs and molds, the search is slow and the measurement efficiency is reduced. Moreover, due to the small difference in the appearance of the hubs of different types or molds, and the lack of experience of new employees, etc., the type of hubs or molds are often misidentified, resulting in calling The measurement program is wrong, causing the collision and damage of the moving parts such as the measuring head of the three-coordinate measuring machine, which has a great impact on measurement and production, resulting in large economic losses
