Description

Technical Field

[0001] The present invention relates to the technical field related to auxiliary modeling tools for making process design modeling software, and in particular to a process point automatic calculation modeling tool and method. Background Art

[0002] With the rapid development of the mechanical field, there are more and more types of parts and components that require a large number of points. The number of points on such products is extremely large. Due to the different product models, the distribution of points is also different. In software modeling, due to the extremely large number of points and the uneven distribution of angles and circles, the workload during modeling is extremely large. The traditional modeling method takes a very long time, and it is very easy for human vision to read the wrong line, resulting in an extremely high error rate.

[0003] In view of the above-mentioned defects, there is an urgent need to design a special auxiliary modeling tool to improve modeling efficiency, save time, reduce the manual links in the modeling process, reduce the error rate, and thus ensure the correctness of the model. Summary of the invention

[0004] In order to solve the problems mentioned above, the present invention proposes a tool and method for automatic calculation and modeling of process points.

[0005] The modeling tool includes: an input layer, a configuration layer, a calculation layer, and an output layer; The input layer is used for the user to input corresponding parameter values ​​according to the product drawing content in the interface of the modeling tool, and the parameter values ​​include: starting angle direction, starting angle value, pitch circle diameter value, hole position quantity, and dimension unit; The configuration layer is used by users to adjust the display and order of attribute table headers and quickly switch between metric and imperial units; The calculation layer is used to calculate according to the parameter values ​​input by the user in the input layer to generate N point cloud coordinate values, where N is a natural number; The output layer is used to package the calculation results of the calculation layer and output a JSON format file, which is used for automatic point creation and reading in Siemens NX.

[0006] Furthermore, a method for automatically calculating and modeling process points is provided, the modeling method comprising the following steps: Step 1: Select the starting angle as clockwise or counterclockwise in the modeling tool according to the angle direction requirements of the drawing; Step 2: Enter the value in the "Polar Angle" of the modeling tool according to the starting angle value given in the drawing; Step 3: Enter the value in the "Pitch Circle Radius / Polar Radius" column of the modeling tool according to the pitch circle diameter value of the point given in the drawing; Step 4: Enter the value in the "Number of Holes" field of the modeling tool according to the number of holes given in the drawing.

[0007] Step 5. Select the input dimension unit as mm or inch according to the drawing dimension unit; Step 6: Based on the parameters input in steps 1 to 5 above, the modeling tool automatically calculates the X and Y coordinate values ​​of all points.

[0008] Step 7: Import the coordinate values ​​output in step 6 into Siemens NX software to complete the rapid creation of the point cloud.

[0009] Furthermore, according to the selected starting angle rotation direction in step 1, the point cloud rotation direction is calculated: When rotating clockwise, the calculation formula is X1*COS(X2*PI) / 180, where X1 is the starting angle and X2 is the incremental angle. When rotating counterclockwise, the calculation formula is X1*SIN(X2*PI) / 180, where X1 is the starting angle and X2 is the incremental angle.

[0010] Furthermore, according to the starting angle value entered in step 2, the point cloud angle increment is calculated: The calculation formula is X1+360 / X2, where X1 is the starting angle and X2 is the incremental angle.

[0011] Further, according to step 3, the pitch circle radius value is calculated according to the input pitch circle diameter value.

[0012] Furthermore, in step 4, the input hole position quantity value is the point position quantity value on the pitch circle.

[0013] Furthermore, in step 5, the dimension unit is mm by default.

[0014] Furthermore, in step 6, the X, Y, and Z coordinate values ​​of all points in the point cloud are calculated according to the formulas in steps 1 and 2 and the parameters input in steps 1 to 5, and a json format file is output.

[0015] Furthermore, in step 7, the GC toolbox is opened in the Siemens NX software, and the engineering file into which the points need to be imported is opened: the "Tools" menu is selected above the main interface of the Siemens NX software, and then "Import Points" is selected. In the "Import Points" dialog box that pops up, the point file type to be imported is selected, and the "OK" button is clicked to import the point information into the engineering file, thereby completing the rapid creation of the point cloud. In addition, point tools can be used for modeling, analysis, and optimization operations in the engineering file.

[0016] The beneficial effects of the present invention are: The present invention, by designing modeling tools and methods, can automatically calculate and output all point coordinate values ​​of any number of holes on different pitch circle sizes at any angle on the circumference in the clockwise and counterclockwise directions according to the number of hole positions designed in the drawings and the technical size requirements; it solves the problems of low modeling efficiency, many manual operation links and high error rate when there are a huge number of hole positions; it achieves a stable, efficient and error-free modeling effect, and reaches the technical effect of reducing manual operation, improving efficiency and reducing error rate.
