[0052] See also Figure 1 , Figure 1 1 is a schematic flow chart of a workpiece positioning method provided in the first embodiment of the present application. In this embodiment, the execution subject of a workpiece positioning method is a device with a workpiece positioning function, such as a server, a PC, etc. Figure 1 The workpiece positioning method shown may include:

[0053] S101: Acquire theoretical position data of a virtual workpiece relative to a virtual fixture, and acquire detection point data; wherein the detection point data is used to determine detection points created on the surface of the virtual workpiece.

[0054] A virtual artifact refers to a 3D modeled artifact stored in a 3D model document.

[0055] A virtual fixture refers to a 3D modeled fixture stored in a 3D model document.

[0056] In an optional implementation, the 3D model file may be opened by corresponding software, and then the theoretical position data of the virtual workpiece relative to the virtual fixture may be measured using tools in the software.

[0057] The theoretical position data of the virtual workpiece relative to the virtual fixture includes a theoretical position value from a reference surface of the virtual workpiece to a center of the virtual fixture.

[0058] See also Figure 2 and Figure 3 , Figure 2 is a display schematic diagram of a virtual workpiece and a virtual fixture provided in an embodiment of the present application, Figure 3 It is a schematic diagram showing the display of theoretical position data provided in an embodiment of the present application.

[0059] Depend on Figure 2 It can be seen that four virtual workpieces 22 are displayed on the virtual fixture 21 , and the reference surfaces of the four virtual workpieces 22 are 221 , 222 , 223 and 224 , respectively.

[0060] Depend on Figure 3 It can be seen that the theoretical position data includes the distance between the center of the reference surface of each virtual workpiece and the center of the fixture, which may include the X distance from the virtual workpiece to the virtual fixture, the Y distance from the virtual workpiece to the virtual fixture, and the Z distance from the virtual workpiece to the virtual fixture. Figure 3 The numerical values ​​are only examples and are not limiting.

[0061] The detection point data is used to determine the detection points created on the surface of the virtual workpiece. Specifically, the detection point data can be obtained in the following ways:

[0062] See also Figure 4 , Figure 4 is a schematic flow chart of S101 in a workpiece positioning method provided in the first embodiment of the present application, where S101 includes:

[0063] S1011: Obtaining a reference positioning method; wherein the reference positioning method includes a reference for positioning a Z distance, a reference for positioning an X distance, a reference for positioning a Y distance, and a parallelism reference.

[0064] The device obtains the reference positioning method, which can also be understood as the detection trajectory of the probe.

[0065] The reference positioning methods include the reference for positioning the Z distance, the reference for positioning the X distance, the reference for positioning the Y distance and the parallelism reference.

[0066] (1) Positioning Z distance reference: construct a plane from three or four points, and this plane serves as the Z reference and flatness reference.

[0067] (2) The X distance positioning reference is the midline of two straight lines parallel to the X axis of the coordinate system as the X reference; or a straight line parallel to the X axis of the coordinate system as the X reference; or the center of a cylinder (hole) as the X reference;

[0068] (3) The datum for positioning the Y distance: the midline of two straight lines parallel to the Y axis of the coordinate system is used as the Y datum; or a straight line parallel to the Y axis of the coordinate system is used as the Y datum; or the center of a cylinder (hole) is used as the Y datum;

[0069] (4) Parallelism datum: Use the straight line of the X datum or Y datum as the parallelism datum.

[0070] S1012: According to the reference positioning method, detection points for constructing planes, straight lines and circles are created on the surface of the virtual workpiece to obtain detection point data.

[0071] The data of each probe point includes at least: (1) the X, Y, and Z coordinate values ​​of the probe point relative to the zero point of the coordinate system; (2) the vector direction of the probe point on the surface, which can be represented by I, J, and K. The data of each probe point can also include: (3) the name and angle of the probe needle used for the probe point; (4) the approach and retraction distances used for the probe point; and (5) the upper and lower tolerances used for the probe point.

[0072] For example: The data of a certain detection point is X=47.793, Y=7.793, Z=-7.000, I=0.000, J=-0.000, K=1.000, probe name=P10E12BY40, angle=T1A0B0, approach=0.500, backoff=0.500, upper tolerance=0.002, lower tolerance=0.002.

[0073] S102: Displaying a workpiece clamping diagram including a virtual workpiece, a virtual fixture, and theoretical position data.

[0074] The device displays a workpiece clamping diagram including a virtual workpiece, a virtual fixture, and theoretical position data, and the workpiece clamping diagram is used to instruct an operator to mount the workpiece on the fixture.

[0075] Specifically, the device can display the workpiece clamping diagram including the virtual workpiece, the virtual fixture and the theoretical position data in response to the workpiece clamping diagram display instruction. The workpiece clamping diagram display instruction can be triggered by the device when the operator queries the workpiece clamping diagram.

[0076] In an optional implementation, in order to make the installation error within a reasonable range, please refer to Figure 5 , Figure 5 is another schematic flow chart of a workpiece positioning method provided in the first embodiment of the present application, and after S102, includes:

[0077] S105: Acquire the actual position data of the workpiece relative to the fixture.

[0078] S106: If the error between the actual position data and the theoretical position data exceeds a preset allowable range, the theoretical position data is modified using the actual position data.

[0079] Measure the actual position data of the workpiece relative to the fixture, input the actual position data of the workpiece relative to the fixture into the device, and the device compares the actual position data with the theoretical position data. If the error between the actual position data and the theoretical position data exceeds the preset allowable range, the actual position data is used to modify the theoretical position data.

[0080] Specifically, when the error between the actual position data and the theoretical position data exceeds the preset allowable range, the current theoretical position data is modified to the actual position data. This is because the theoretical position data is only a reference data and is used to guide the operator in installation. Certain errors may occur during actual installation. Therefore, it is necessary to control the error within the allowable error range. The theoretical position data is modified here because the fixture has locked and leveled the workpiece. Modifying the theoretical position data can improve positioning efficiency.

[0081] S103: Obtain a program template file of the machine tool, and generate a workpiece positioning program according to the program template file and the detection point data; wherein the workpiece and the fixture installed according to the workpiece clamping diagram are placed together on the machine tool.

[0082] Program template files refer to the basic program files of machine tools, which can be recognized by the machine tool controller.

[0083] In an optional implementation, the program template file includes at least a plane template file, a straight line template file, and a circular template file.

[0084] The device obtains the program template file of the machine tool, and generates a workpiece positioning program according to the program template file and the detection point data.

[0085] Specifically, the device writes the detection point data for constructing a plane, the detection point data for constructing a straight line, and the detection point data for constructing a circle into a plane template file, a straight line template file, and a circle template file, respectively, to obtain a workpiece positioning program.

[0086] In addition to writing the detection point data into the program template file, it is understandable that statements for guiding the operation of the machine tool need to be added to the program template file to ensure that the machine tool can run the generated workpiece positioning program.

[0087] S104: driving the machine tool to measure target position data of the workpiece relative to the fixture according to the workpiece positioning program.

[0088] The device drives the machine tool to measure the target position data of the workpiece relative to the fixture according to the workpiece positioning program. That is, the device controls the machine tool to execute the workpiece positioning program, thereby measuring the target position data of the workpiece relative to the fixture.

[0089] In an optional embodiment, the device stores the workpiece positioning program in the machine tool, calls the interface protocol of the machine tool, sends a program execution instruction to the machine tool, and causes the machine tool to respond to the program execution instruction and execute the stored workpiece positioning program.

[0090] For example, for 4 workpieces, the target position data includes:

[0091] Workpiece 1: X=57.506, Y=38.325, Z=57.135, angle=1.105, flatness=0.003;

[0092] Workpiece 2: X=54.506, Y=-32.105, Z=57.132, angle=-0.105, flatness=0.003;

[0093] Workpiece 3: X = -62.116, Y = 42.305, Z = 57.131, angle = -2.003, flatness = 0.004;

[0094] Workpiece 4: X=-63.437, Y=-32.752, Z=57.135, angle=0.605, flatness=0.001.

[0096] S107: Receive target position data of the workpiece relative to the fixture.

[0097] S108: In response to the position data display instruction, a position data display page is loaded, and the target position data of the workpiece relative to the fixture is presented in the position data display page.

[0098] The device receives the target position data of the workpiece relative to the fixture, the operator queries the position data, triggers the device to generate a position data display instruction, the device responds to the position data display instruction, loads the position data display page, and presents the target position data of the workpiece relative to the fixture on the position data display page, so that the operator can intuitively and conveniently understand the target position data of the workpiece relative to the fixture.

[0099] In this embodiment, the device obtains theoretical position data of the virtual workpiece relative to the virtual fixture, and obtains detection point data; wherein the detection point data is used to determine the detection points created on the surface of the virtual workpiece; displays a workpiece clamping diagram containing the virtual workpiece, the virtual fixture and the theoretical position data; obtains the program template file of the machine tool, and generates a workpiece positioning program according to the program template file and the detection point data; wherein the workpiece and the fixture installed according to the workpiece clamping diagram are placed together on the machine tool; and the machine tool is driven according to the workpiece positioning program to measure the target position data of the workpiece relative to the fixture.
