With the gradual and wide popularization and use of automatic processing, the problem that batch parts cannot be automatically processed occurs. At present, automatic machining operation is performed in a mode of one part and one tray, that is, one part is machined by using one zero point positioning fixture (or may be called as a zero point positioning jig), and only one part can be machined at a time. When a scene that batch parts need to be processed is faced, the zero positioning fixture is large in input amount, large in workload of repeatedly clamping the parts, large in labor input, high in cost, incapable of increasing the part processing amount, high in part operating frequency and capable of seriously reducing the efficiency that the batch parts cannot be automatically processed. The robot needs to send each part to a designated device frequently for processing, so that the robot is frequently used, and the service life of the robot is shortened.
In view of the above, the present application provides a method and an apparatus for automatic batch part machining, in which a plurality of identical parts are clamped on a zero-point positioning jig, deviation data of each part on the zero-point positioning jig is determined by a three-coordinate measuring machine calibration, the deviation data is stored in a system, and a numerically controlled milling (CNC) machining program and an Electrical Discharge Machining (EDM) machining program are integrated and stored in the system.

The method for automatically processing the batch parts provided by the application is described below by combining specific examples.
Fig. 1 is a schematic flow chart illustrating an example of the method for automatically processing a batch of parts provided by the present application.
It should be understood that the method provided by the present application is executed by a control device for automated processing. The automatic processing control device is used for controlling various machine tools and robots in the automatic processing system to cooperatively work to complete a preset automatic processing task. The control device for the automated processing may be an independent control device, such as a server, a computer, or a terminal device having both computing and communication capabilities. Alternatively, the automatic processing control device may be an arithmetic processing module integrated in the machine tool or the robot, and the purpose of controlling the automatic processing of the part may be achieved by communication between the machine tool and the robot.
As shown in fig. 1, the method includes:
and S110, determining information of a plurality of parts clamped on the same zero positioning clamp.
In S110, it can be determined how many parts need to be clamped on the same zero point positioning jig, that is, how many parts need to be machined at a time. For example, the pitch between the respective parts can be determined according to the part size data, and the number of the parts mounted on the zero point positioning jig can be determined.
It should be understood that the parts clamped by the same zero point positioning jig are the same parts, and for example, the names, sizes, types, and the like of the parts are the same.
For example, the number of the parts clamped by the same zero point positioning fixture may be 2 to 8. It should be understood that, in the embodiment of the present application, the number of the parts clamped by the same zero point positioning fixture may also exceed 8, and the number of the parts may be determined according to actual needs of machining.
After the number of the parts clamped by the same zero positioning fixture is determined, the parts needing to be clamped together are found and numbered, and the parts are placed in a tray of the zero positioning fixture on a correction table for clamping and positioning. The tray is transferred among different processing devices along with the parts, and the zero point positioning clamp on the correction table is not moved.
Exemplarily, in the process of clamping and positioning, a dial indicator can be used for aligning the rotation degree, the flatness and the verticality of each part, so that the clamping and positioning work can be carried out in the system.
For example, after the information of the parts clamped by the same zero-point positioning fixture is determined, the "multi-workpiece clamping" function key can be clicked by hooking and selecting the clamped parts on the system clamping material preparation page, the system can automatically combine the selected parts together, and the information of the parts clamped by the same zero-point positioning fixture is transmitted to a chip or a system for storage through a reader-writer or other modes.
For example, the information for the part may include: name, number, size, type of part, etc. The embodiments of the present application are not limited thereto.
S120, combining a plurality of different processing programs into one main program and storing the main program, wherein the processing programs comprise: CNC machining programs, EDM machining programs.
In the embodiment of the present application, a machining program for a part to be machined may be integrated, for example, the machining program for the part may include: CNC machining programs, EDM machining programs (or may also be referred to as electrical discharge placement programs), and the like. The embodiments of the present application are not limited thereto.
For example, in the embodiments of the present application, the EDM machining program may be according to: deviation data [ X, Y, Z ] of each part from a basic coordinate system on a discharge machine tool, spark gap, electrode discharge run-out data [ X, Y, Z ], and the like. The electrode discharge run-out data can be understood as the position coordinates of the discharge electrode discharging on the part, namely the position data of the discharge electrode discharging on the part.
After a plurality of machining programs for machining parts are acquired, the plurality of machining programs can be converted through a program conversion file (namely a POST file), and a main program generated by arranging is stored in the system. When the machining is carried out, the corresponding part machining program is called from the system according to different programs needing machining.
In the process of storing a plurality of machining programs for a part, the machining programs may be stored in association with IDs of the machining programs, and the corresponding machining programs may be acquired by the IDs of the machining programs. Optionally, the ID or name of each part and the ID of the machining program corresponding to the part may be stored, so that the ID of the corresponding machining program may be acquired according to the ID or name of the part, and the corresponding machining program may be further acquired. Since the parts clamped by the same zero point positioning fixture are the same, the names of the parts are the same, but the IDs of the different parts are different, the parts clamped by the same zero point positioning fixture correspond to the same CNC machining program or the same EDM machining program.
And S130, determining deviation data of each part in the basic coordinates of the zero positioning clamp and storing the deviation data.
After the plurality of parts are clamped and positioned by one zero point positioning clamp, the clamped part tray is sent into a three-coordinate measuring machine to be corrected, and deviation data of the parts are obtained.
Because each part has its own corresponding coordinate system, the coordinate systems of different parts are different, and a plurality of parts are clamped on the same zero point positioning fixture, the zero point positioning fixture also has its own coordinate system, and the coordinate system on the zero point positioning fixture can be called as a basic coordinate system. Therefore, it is necessary to determine deviation data [ X, Y, Z ] between the coordinate system of each part itself and the base coordinate system on the zero point positioning jig. The deviation data [ X, Y, Z ] is used to determine the position of each part in the base coordinate system on the zero point positioning fixture. In other words, the deviation data [ X, Y, Z ] indicates: the offset or relative difference between the coordinate system of each part itself and the base coordinate system on the zero-point positioning fixture.
Since each machining device (e.g., three-coordinate measuring machine, CNC device, electric discharge machine, etc.) has a zero-point positioning fixture, the zero-point positioning fixtures on different devices are identical, and each zero-point positioning fixture has its own basic coordinate system. The center points of the zero point positioning fixtures on different devices are all located at the same position of the zero point positioning fixture, that is, the center points of the zero point positioning fixtures on different devices are located at the same position, the center points (that is, the coordinate origin) of the basic coordinate systems of the zero point positioning fixtures on different devices are all located at the center point of the zero point positioning fixture, and the origin of the basic coordinate systems of the zero point positioning fixtures on different devices is located at the same position. Therefore, the deviation data between the coordinate system of each part itself and the base coordinate system on the zero point positioning jig is the same for the base coordinate systems of the zero point positioning jigs on different apparatuses. In other words, the amount of offset or the relative difference between the coordinate system of the part itself and the base coordinate system of the zero point positioning jig is the same for the base coordinate systems of the zero point positioning jigs on different machining apparatuses, i.e., the deviation data [ X, Y, Z ] corresponding to the base coordinate systems of the zero point positioning jigs on different machining apparatuses is the same.
Deviation data of each part with respect to a coordinate system on the zero point positioning jig can be acquired in the three-coordinate measuring machine. For example: a plurality of parts to be corrected (a plurality of parts are placed on a pallet) may be arranged on a coordinate measuring machine, and the number of each part may be determined on the coordinate measuring machine to perform the correction work. Using a three-coordinate measuring machine, a zero point positioning jig (for the sake of distinction, the zero point positioning jig on the three-coordinate measuring machine is referred to as a first zero point positioning jig, and a basic coordinate system on the first zero point positioning jig is denoted as [ X ]1、Y1、Z1]Determining the deviation of each part's own coordinate system from the basic coordinate system on the first zero-point positioning fixture [ X, Y, Z ]]The deviation data [ X, Y, Z]For determining the position of each part in a coordinate system on the first zero point positioning fixture.
In the manner described above, deviation data corresponding to all parts can be determined [ X, Y, Z ], submitted to a system database, or transmitted to a chip for storage by a reader/writer or other means. This completes the part calibration process.
Optionally, when storing the deviation data of each part, the ID information of each part and the deviation data of each part may be stored in correspondence, so that the deviation data of the part may be acquired by the ID of the part.
And S140, calling the respective corresponding processing programs of different processing procedures and the deviation data of each part, and processing the workpiece respectively.
Optionally, in this embodiment of the application, as shown in fig. 2, S140 may include S141 to S144.
And S141, CNC machining is carried out on the plurality of parts by the CNC according to the CNC machining program, the base coordinate system of the zero point positioning clamp on the CNC and deviation data of the parts in the base coordinate system of the first zero point positioning clamp.
After the correction is finishedThereafter, the pallet with the parts mounted thereon is transferred to a CNC (numerical control machining center) by a robot to be machined. The pallet with the parts mounted thereon is assembled to a zero point positioning jig on the CNC (for distinction, the zero point positioning jig on the CNC is referred to as a second zero point positioning jig. the CNC acquires the part name and the ID in the system database, downloads the corresponding CNC machining program in the system according to the part name, and acquires deviation data of each part from the system according to the ID information of each part [ X, Y, Z ]]Introducing the deviation data of each part into the basic coordinate system [ X ] of the second zero point positioning fixture2、Y2、Z2]And (4) the following steps. It should be understood that the deviation data for each part [ X, Y, Z]Is determined in S130, and represents the offset or relative difference of the own coordinate system of each part and the basic coordinate system on the first zero point positioning jig, that is: each part's own coordinate system and the basic coordinate system [ X ] on the second zero point positioning fixture2、Y2、Z2]And the coordinate system of each part and the basic coordinate system [ X ] on the first zero point positioning jig1、Y1、Z1]The deviation data of (a) are the same.

In S143, the tray with the non-defective parts is transferred to the electric discharge machine tool by the robot, and the tray with the non-defective parts is mounted on a zero point positioning jig on the electric discharge machine tool (for the purpose of distinction, the zero point positioning jig on the electric discharge machine tool is referred to as a third zero point positioning jig, and a basic coordinate system of the third zero point positioning jig is referred to as [ X ] X3、Y3、Z3]. The electric discharge machine obtains part names and ID information in a system database, downloads a corresponding EDM program in the system according to the name of each part, and obtains deviation data of each part from the system according to the ID information of each part [ X, Y, Z ]]Introducing the deviation data of each part into the basic coordinate system [ X ] of the third zero positioning fixture3、Y3、Z3]In (1).
