Manipulator cutting processing detection system and manipulator cutting processing detection method

Abstract

The invention discloses a manipulator cutting machining detecting system which comprises a mechanical arm, a cutter component, an installation component, a numerical control system and an on-line detecting unit, wherein the installation component is used for installing the cutter component on the mechanical arm; the numerical control system is used for controlling the machining path of the cutter component through a servo system; the on-line detecting unit is mounted on the mechanical arm and comprises a detection installation plate fixed on the mechanical arm, a detection head mounted on the detection installation plate, and an error evaluation system; the detection head is connected with the error evaluation system, detects a machined workpiece according to a preset procedure, and feeds back the detection result to the error evaluation system; the error evaluation system compares the detection result with a given machined model; and if the detection result exceeds a preset error range, the numerical control system generates a new machining path, and the cutter component remachine the machined workpiece.

Description

technical field [0001] The invention relates to the field of manipulator cutting, in particular to a manipulator cutting detection system and a manipulator cutting detection method. Background technique [0002] In the cutting process, machining accuracy inspection is a very important step; when the parts are processed, a large number of accuracy inspections need to be completed, mainly including workpiece machining dimension error detection, workpiece surface processing quality inspection, etc. [0003] At present, the methods of component precision testing mainly include manual testing, offline three-coordinate instrument testing, and online testing. Manual inspection uses conventional measuring tools such as dial gauges and calipers for manual calibration and inspection. Its efficiency is low, and the accuracy is easily affected by human beings, which affects the utilization rate of the machining center and the automatic processing process of the product. Off-line detect...

Problems solved by technology

Manual inspection uses conventional measuring tools such as dial gauges and calipers to manually calibrate and inspect. Its efficiency is low, and the accuracy is easily affected by human beings, which affects the utilization rate of the machining center and the automatic processing process of the product.

Off-line detection is to remove the workpiece from the machining center between processing procedures or after processing, and use other detection equipment for detection, that is, processing and dimensional accuracy detection are not carried out on the same equipment, and the two are not synchronized, the secondary positioning of the workpiece And clamping will bring original errors, which is not conducive to ensuring the machining accuracy of parts; at the same time, repeated unloading and clamping will reduce production efficiency; in addition, for large-scale processing workpieces, the offline detection process is complicated and time-consuming, and is not suitable for large-scale automated production process
