Problems solved by technology

At present, the workpiece accuracy measurement of CNC machine tools can only be stopped for on-site inspection after a certain process is completed, or it can be moved to a special inspection platform for accuracy measurement, which seriously affects the processing efficiency
Since the existing measurement methods all adopt the contact measurement method, it is impossible to realize real-time online measurement when the CNC machine tool is working, which restricts the development of real-time precision compensation technology of the CNC machine tool and limits the further improvement of the machining accuracy of the CNC machine tool

Abstract

The invention discloses a real-time online monitoring device for a workpiece of a numerical control machine tool, and belongs to the technical field of machine tool equipment. A sensor installing base is fixedly connected to a transition plate through screws, a laser sensor is installed on the sensor installing base, a movable connector is arranged at the end part of a data transmission cable of the laser sensor, the transition plate is fixedly connected to a transverse and longitudinal displacement adjusting device through a taper shank blind rivet on the upper portion of the transition plate, a fixed connector is installed on the lower end face of the transverse and longitudinal displacement adjusting device, the movable connector is connected to the fixed connector, a data transmission cable connected to the tail end of the fixed connector is connected to an upper computer, the transverse and longitudinal displacement adjusting device is located on the left side of a workpiece on a machine tool workbench, a tool is located on the right side of the workpiece on the machine tool workbench, the transverse and longitudinal displacement adjusting device controls the laser sensor to keep making non-contact with the workpiece, the laser sensor measures the displacement value between the laser sensor and the surface of the workpiece on line in real time under the cutting state of the machine tool, and precision data such as various errors of the workpiece can be obtained by resolving measurement data through the upper computer.

Description

technical field [0001] The invention relates to a real-time on-line monitoring device for CNC machine tool workpieces, belonging to the technical field of machine tool equipment. Background technique [0002] Due to the characteristics of large size and large load, large CNC machine tools often produce a large amount of removal when processing large workpieces, and the error of workpieces increases in a large scale range. At present, the workpiece accuracy measurement of CNC machine tools can only be stopped for on-site inspection after a certain process is completed, or it can be moved to a special inspection platform for accuracy measurement, which seriously affects the processing efficiency. Since the existing measurement methods all adopt the contact measurement method, it is impossible to realize real-time online measurement when the CNC machine tool is working, which restricts the development of real-time precision compensation technology of the CNC machine tool and li...
