The integrated workbench is mainly composed of four guide pillars respectively placed on the chassis, and the guide cylinder bearings are respectively inserted into the four guide pillars. Four anti-collision bars, connecting plates, two cylinders and EROWA clamps are respectively fixed to the chassis, and the tray is set in the four guide cylinder bearings and two piston rods. The four top columns are respectively fixed to the tray; the fixture is mainly fixed on the upper end surface of the fixture base by several studs, three positioning baffles, two handles and a rectangular positioning baffle are respectively fixed on the side end surfaces around the fixture base, and the positioning plates and rivets are respectively fixed on the lower end surface of the fixture base; the fixture is connected and fixed to the EROWA clamp on the integrated workbench through rivets.

[0003] However, the defects of the prior art are also obvious, that is, ordinary electrodes cannot be quickly clamped using the EROWA clamp, which makes it difficult to improve the processing cost and benefit of the spark machine. Summary of the invention

[0004] The purpose of the present invention is to provide a processing method of a spark machine to solve the problems existing in the prior art.

[0005] The object of the present invention is achieved in this way: a processing method of a spark machine, comprising:

[0006] Quick clamp change, using the conversion operation of EROWA fixture and universal chuck. After the electrode is calibrated by the universal chuck, the detection device is used to measure the offset data between the electrode center and the EROWA fixture center.

[0007] The system records the detection data of the electrode and uses the data center to store the offset data of the corresponding electrode so that the offset data can be used in the subsequent generation of the corresponding processing formula.

[0008] Furthermore, the universal chuck is adjustably connected to the EROWA fixture, and the universal chuck has at least two horizontal adjustment directions, namely, XY.

[0009] Furthermore, the detection device used in the method is provided with a detection platform, on which detection component one and detection component two are slidably connected, and detection component one and detection component two are respectively adjusted horizontally in the X direction and in the Y direction on the detection platform along their respective tracks.

[0010] Furthermore, when using detection component 1 and detection component 2 to detect the offset data between the electrode center and the EROWA fixture center, X-direction and Y-direction detection are performed on a horizontal reference plane to respectively detect the horizontal X distance and horizontal Y distance between the electrode center and the EROWA fixture center.

[0011] Furthermore, the electrode positions required for processing on the mold are exported as NC programs through UG or CAM software, and recognizable names are defined. The CNC system of the spark machine reads the NC program of each electrode corresponding to the mold processing position through local connection, WAN connection or USB flash drive, and calls the discharge parameters through Q instructions to execute processing.

[0012] Furthermore, an RFID chip is installed on each electrode as an identification tag.

[0013] Furthermore, the processing position and discharge parameters of the electrode are automatically programmed through UG software or CAM software, the identity of the electrode is identified through RFID recognition or QR code recognition, the processing information is read, and the corresponding processing NC program is called.

[0014] Furthermore, the factory's MES system is coupled with the CNC system of the EDM machine tool to record the processing information.

[0015] Furthermore, the processing information includes the utilization rate of the EDM machine, electrode processing time and parameters, and overall mold production time.

[0016] The beneficial effects of the present invention are:

[0017] 1. Ordinary electrodes (electrodes that do not use standard fixtures) can also be quickly clamped using EROWA fixtures;

[0018] 2. The relevant information of the electrode (including the measured offset) can be used to automatically generate and call the machining NC program to improve the machining efficiency;

[0019] 3. Provides an intelligent electrode management solution based on RFID identification, combining electrodes with RFID. Each electrode has a special ID so that it can be accurately identified during the processing, so that the processing can be accurately controlled, and intelligent communication between products and equipment can be achieved, effectively avoiding many problems such as chaotic process management due to untimely data collection.

[0023] The following will be combined with the attached embodiment of the present invention Figure 1-3 , the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The processing method of the spark machine may include the following three embodiments.

[0025] like Figure 1 As shown, the electrode 3 is adjusted by a special electrode debugging machine, and the electrode 3 is clamped by a traditional universal chuck 2, and the universal chuck 2 is adjustably connected to the EROWA fixture 1, and the universal chuck 2 has at least two horizontal adjustment directions of XY; the electrode debugging machine also has a special detection platform 6, and a detection component 1 4 and a detection component 2 5 are slidably connected to the detection platform 6. The detection component 1 4 and the detection component 2 5 are respectively adjusted horizontally in the X direction and the Y direction on the detection platform along their respective tracks.

[0026] The first embodiment corresponds to the quick clamping step, specifically: using the conversion operation of the EROWA clamp 1 and the universal chuck 2, after the electrode 3 is calibrated by the universal chuck 2, a detection device is used to measure the offset data between the center of the electrode 3 and the center of the EROWA clamp 1, thereby achieving the purpose of quick clamping of ordinary electrodes (electrodes that do not use standard clamps) using the EROWA clamp.

[0027] When measuring the offset data between the center of the electrode 3 and the center of the EROWA fixture 1, a special detection device is required for detection, using detection component 1 4 and detection component 2 5 for detection, and performing X-direction and Y-direction detection on a horizontal reference plane respectively to detect the horizontal X distance and horizontal Y distance between the center of the electrode 3 and the center of the EROWA fixture 1 respectively.

[0028] The system records the detection data of the electrode and uses the data center to store the offset data of the corresponding electrode so that the offset data can be used in the subsequent generation of the corresponding processing formula.

[0029] The second embodiment is an automated mode (such as Figure 2 ), specifically:

[0030] 1. By using the conversion operation of the EROWA fixture 1 and the universal chuck 2, after the electrode 3 is calibrated by the universal chuck 2, the offset data between the center of the electrode 3 and the center of the EROWA fixture 1 is measured, so that the purpose of quickly changing the clamp of the ordinary electrode using the EROWA fixture can be achieved (the same as the first embodiment).

[0031] 2. Use UG or CAM software to export the NC program for the electrode position that needs to be processed on the mold and define a recognizable name. The CNC system of the spark machine reads the NC program for each electrode corresponding to the mold processing position through local connection (spark machine LAN connection), WAN connection or U disk, and calls the discharge parameters through Q instructions to execute processing.

[0032] The third embodiment is a semi-automatic mode (such as Figure 3 ), specifically:

[0033] 1. The conversion operation of the EROWA fixture 1 and the universal chuck 2 is adopted. After the electrode 3 is calibrated by the universal chuck 2, the offset data between the center of the electrode 3 and the center of the EROWA fixture 1 is measured, so that the purpose of quickly changing the clamps of the EROWA fixture can be achieved even for ordinary electrodes; The third embodiment is different from the first embodiment / the second embodiment in that, in the third embodiment, an RFID chip is installed on each electrode as an identification tag (the RFID chip of the electrode can be sensed subsequently using special equipment).

[0034] 2. Automatically program the processing position and discharge parameters of the electrode through UG software or CAM software, identify the identity of the electrode through RFID recognition or QR code recognition, read the processing position, processing requirements, offset data and other processing information, and call the corresponding processing NC program, and then perform EDM.

[0035] The factory's MES system is coupled to the CNC system of the EDM machine, which can record processing information such as the EDM machine's utilization rate, electrode processing time and parameters, and overall mold production time. The data center stores the processing information, and the processing information is not limited to the types listed in this embodiment.

[0036] The advantages of the above solution are as follows:

[0037] Reduce labor;

[0038] Reduce costs;

[0039] With lower input cost and maximum benefit return;

[0040] Can improve efficiency by more than 30%;

[0041] By timely collecting the status of work-in-process and production process, data support is provided for MES, ensuring that MES can timely schedule production for each workstation, so that each workstation can complete the maximum amount of operations, reduce idle time and improve production efficiency.
