Embodiment Construction

[0016] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0017] CNC machine tools have various inspection tasks in the process of processing, including determining the programming origin of parts, inspecting the first part, inspecting between processes, and inspecting after processing. On-site automatic measurement can measure the accuracy of the workpiece without losing the origin and original accuracy of the machine tool. Therefore, research on in-situ measurement technology for CNC machine tools will be an important link to realize the seamless link between measurement and manufacturing. The invention provides an on-site automatic measurement laser a...

Abstract

The invention relates to an in-place automatic measurement laser and machine vision measurement machine supporting numerical control machining. The in-place automatic measurement laser and machine vision measurement machine comprises a small arm assembly, a large arm assembly, a sucking disc base assembly and anti-cutting-chipping cover assemblies; the small arm assembly is connected with the large arm assembly through a small arm base and is provided with a reducer B and a small arm swing motor which control a small arm to swing, and a measurement probe set is installed at the front end of a center shaft of a wrist; and the large arm assembly is connected with the sucking disc base assembly through a drive arm base, the sucking disc base assembly is fixedly connected with the drive arm base through a bolt, and the anti-cutting-chipping cover assemblies are welded to the two sides of the sucking disc base assembly. By means of the in-place automatic measurement laser and machine vision measurement machine, laser distance measurement and workpiece dimension machine vision measurement serve as basic measurement tools, the measurement machine and a numerically-controlled machine tool are compatible, cutting cover protection is achieved, automatic focusing is achieved, automatic binding with a main shaft and independent control are achieved, and numerical control cooperative work is achieved through mechanical innovation.

Description

technical field [0001] The invention relates to a measuring machine device, in particular to a laser and machine vision measuring machine mechanism supporting in-situ automatic measurement of numerical control processing. Background technique [0002] Commonly used measurement methods can be divided into three types: off-line measurement, on-site measurement and on-line measurement. Off-line measurement refers to the measurement in the inspection room after the processing is completed. The measurement and processing process are separated. If the measurement is unqualified, it needs to be re-clamped for repair, which is prone to clamping errors. There is no need to unload the workpiece and measure directly on the machine tool table; on-line measurement refers to real-time measurement during the processing process, to grasp the processing error and change trend at any time, and to control it in time, which is a dynamic measurement process. Theoretically speaking, online measu...
