Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
When cutting equipment in the prior art is used for cutting a workpiece, a positioning tool needs to be assembled on the workpiece for positioning the workpiece. Especially for the special-shaped space thin-wall component without the regular molded surface, the structure of the positioning tool is relatively complex, the design difficulty is high, and the processing cost is increased.
Fig. 1 shows a flowchart of a positioning and cutting method provided by an embodiment of the present invention. As shown in fig. 1, an embodiment of the present invention provides a positioning cutting method, which is applied to a cutting apparatus, where the cutting apparatus includes a cutting actuator, and the method includes:
and 110, measuring the workpiece by using a measuring mechanism to obtain the measurement data of the workpiece.
The cutting devices of the prior art are not provided with a measuring mechanism. In order to implement the positioning cutting method provided by the embodiment of the invention, the cutting equipment is additionally provided with a measuring mechanism for measuring the workpiece and obtaining corresponding measuring data of the workpiece.
In some embodiments, the measuring mechanism has its relatively independent measuring coordinate system with respect to the cutting device, and the directly measured data (which may be the coordinates of the contour points of the workpiece surface) is also data in the measuring coordinate system of the measuring mechanism. However, the theoretical model of the workpiece is usually stored in the data processing mechanism of the cutting apparatus, and the planning operation of the cutting edge line is also performed by the data processing mechanism of the cutting apparatus, so that the measurement data collected by the measurement mechanism needs to be transformed in a manner such that the actual model constructed based on the measurement data is in the same coordinate system as the theoretical model of the workpiece, more specifically, in the cutting coordinate system of the cutting apparatus.
Step 120, building an actual model of the workpiece according to the measurement data of the workpiece.
In some embodiments, constructing an actual model of the workpiece from the measurement data of the workpiece comprises: determining a spatial position of the measuring mechanism relative to the cutting device; determining the coordinates of the measuring mechanism in a cutting coordinate system of the cutting device according to the spatial position of the measuring mechanism relative to the cutting device; and constructing an actual model of the workpiece in the cutting coordinate system of the cutting device according to the coordinates of the measuring mechanism in the cutting coordinate system of the cutting device and the measurement data of the workpiece in the measuring coordinate system of the measuring mechanism.
In this embodiment, the coordinates of the measuring mechanism in the cutting coordinate system of the cutting device may be determined by measuring the spatial position of the measuring mechanism relative to the cutting device in advance. In order to increase the efficiency of the measurement of the spatial position of the measuring means relative to the cutting device, the measuring means is preferably arranged in the vicinity of the cutting head of the cutting device. In some examples, when the cutting device selects the three-dimensional laser cutting device, the measurement mechanism may employ a three-dimensional scanner, which may be disposed in proximity to a laser head of the three-dimensional laser cutting device.
Furthermore, according to the coordinates of the measuring mechanism in the cutting coordinate system of the cutting device and the measurement data of the workpiece in the measurement coordinate system of the measuring mechanism, the measurement data of the workpiece can be transformed into the cutting coordinate system of the cutting device through coordinate transformation, and then an actual model of the workpiece is constructed according to the measurement data transformed into the cutting coordinate system of the cutting device. Here, the cutting coordinate system of the cutting apparatus may be a system coordinate system of the cutting apparatus, or a machine coordinate system of the cutting apparatus. Therefore, the actual model of the workpiece and the theoretical model of the workpiece are in the same coordinate system, and the actual model and the theoretical model of the workpiece can be matched.
In some examples, when the cutting device selects a three-dimensional laser cutting device, the measuring mechanism employs a three-dimensional scanner, the measuring mechanism can acquire three-dimensional measurement data of the workpiece, and the actual model of the workpiece constructed based on the three-dimensional measurement data is a three-dimensional model of the workpiece. For the special-shaped space workpiece, a regular molded surface for positioning does not exist, so that only a three-dimensional model can be constructed for the workpiece, the cutting edge line of the workpiece is determined based on the matching result between the three-dimensional model of the workpiece and the theoretical model, and finally cutting is realized according to the cutting edge line.
And step 130, matching the actual model of the workpiece with the theoretical model of the workpiece, and determining the cutting edge line of the workpiece.
In some embodiments, said matching the actual model of the workpiece with the theoretical model of the workpiece to determine the cut edge line of the workpiece comprises: when the actual model of the workpiece is matched with the theoretical model of the workpiece, the molded surfaces of the actual model of the workpiece and the theoretical model of the workpiece are attached to each other; and determining a cutting edge line of the workpiece according to the part of the mismatch between the actual model of the workpiece and the theoretical model of the workpiece.
Specifically, when the molded surfaces of the actual model and the theoretical model of the workpiece are attached to each other, the machining allowance of the workpiece can be compared, the part of the machining allowance is the part of the workpiece which is not matched between the actual model and the theoretical model, and the cutting edge line of the workpiece can be planned according to the machining allowance.
And 140, controlling the cutting executing mechanism to cut the workpiece according to the cutting edge line of the workpiece.
Specifically, the cutting operation of the workpiece is performed by a cutting actuator of the cutting apparatus.
In summary, an embodiment of the present invention provides a positioning cutting method, which is applied to a cutting apparatus, where the cutting apparatus includes a cutting execution mechanism, and the method includes measuring a workpiece by using the measurement mechanism to obtain measurement data of the workpiece, then constructing an actual model of the workpiece according to the measurement data of the workpiece, matching the actual model of the workpiece with a theoretical model of the workpiece, determining a cutting edge line of the workpiece, and finally controlling the cutting execution mechanism to cut the workpiece according to the cutting edge line of the workpiece. Based on the method, the workpiece can be quickly positioned and cut under the condition of no special tool, the cutting efficiency of the workpiece is improved, and the cutting cost is reduced.

The coordinate accuracy of data points obtained by a three-dimensional scanner can be calibrated by a workpiece having a regular shape.
And step three, matching the three-dimensional model generated by the three-dimensional scanner 2 with the theoretical model of the workpiece, wherein the main molded surfaces are in consistent fit, extracting the cutting edge line by the main control computer 3, and calculating the position of the cutting edge line under the machine tool coordinate system according to the relative position of the three-dimensional scanner and the laser cutting machine.
