Abstract

Disclosed is a non-contact type flexible on-line dimension measurement system. A laser displacement sensor, an industrial camera and a power supply are fixed at the tail end of an industrial robot, and the robot saves measuring positions of workpieces to a robot moving track program through a teaching programming in advance. After the workpieces are placed on a measuring bracket and fixedly clamped, the robot drives the displacement sensor, the industrial camera and the power supply to operate to each measurement point on the workpieces for measurement according to pre-programmed programs; when the robot operates to each measurement point, the robot sends a measurement permission instruction to a measurement sensing system, a control system of the measurement sensing system performs measurement and real-timely sends measurement results to a measurement data saving and querying data base, subsequently, the control system of the measurement sensing system informs the robot of operation to the next measurement point, and the whole system repeatedly performs the above circulation to accomplish measurement work of one workpiece at all measurement points. By means of the non-contact type flexible on-line dimension measurement system, efficiency of measurement of automobile parts is improved, measurement samples are multiple, and measurement results are accurate.

Description

Technical field: [0001] The invention relates to the field of physics, in particular to measurement technology, in particular to an automatic measurement technology for size monitoring of parts and components in the production process of auto parts, in particular to a non-contact flexible online size measurement system. Background technique: [0002] In the production process of auto parts, auto parts need to be tested according to the geometric tolerance requirements (GD&T) provided by the customer. The detection method in the prior art is to first make a measuring fixture, place the tested part on and position it, and use the pre-precisely processed and accurately calibrated analog block or chuck on the fixture to focus on the component concerned. Or feature points for measurement. However, this kind of special measuring fixture is only for the special inspection of a specific component and cannot be used for the measurement of other parts, and the analog block or chuck on the...
