A penetrating electrode liquid channel 1201 is opened, and the electrode liquid channel 1201 communicates with the punching channel 1101; one of the necessary conditions for realizing arc micro-explosion processing is the inner flushing liquid. The processing device 100 is provided with an inner flushing device 110 and a tool electrode 120, It is ensured that a single processing device 100 can realize a single arc microburst processing.

The power device 200 is configured to drive any number of rotations in each processing device 100, that is, the power device 200 only drives any one of the processing devices 100 to rotate in a single event, and can drive all the processing devices 100 to rotate at the same time. The processing device 100 in the rotating state can realize cutting processing.

Combining the processing device 100 and the power device 200, the arc micro-blast processing and cutting processing of the composite processing equipment are realized.

In the actual use of arc microblasting processing, if there is only one processing device 100, for the processing of multiple workpieces 400, multiple equipment is used to process at the same time in order to improve the efficiency. The equipment cost is difficult to control, and for single large workpiece 400 processing, The method of enlarging the cross section of the electrode is usually adopted, but this method will seriously affect the size range of the workpiece 400 to be processed.

Then, for the processing of multiple workpieces 400, the power device 200 can drive At least two processing devices 100 are operated in parallel, that is, a single device can process at least two workpieces 400. In this way, the number of equipment and the cost of equipment are reduced. For a single large workpiece 400, the power unit 200 can be processed according to The size of the area to be processed of the workpiece 400 drives at least two processing devices 100 to operate in parallel. In this way, there is no need to enlarge the electrode cross section of the tool electrode 120 in the processing device 100 and the processing efficiency is ensured.

It can be seen from the above that, based on the structural design of the present application, the processing cost of multiple workpieces 400 is reduced, and the processing efficiency of large workpieces 400 is improved.

It should be noted here that in the working condition of multi-workpiece 400 processing, if the number of processing devices 100 is more than the number of workpieces 400, since the power device 200 is configured to drive any number of rotations in each processing device 100, the power The device 200 can only drive the corresponding number of processing devices 100 to operate in parallel, so as to avoid unnecessary idle rotation of the processing device 100; and in the working condition of processing a large workpiece 400, similarly, as the processing of each processing device 100 If the area is larger than the required processing area, the power device 200 can only drive the corresponding number of processing devices 100 to operate in parallel, avoiding unnecessary idling of the processing device 100.

It should be noted here that the structure of the power device 200 is based on its structural purpose. A single driving motor can be used as a driving source, and the rotation of each processing device 100 can be driven by the star wheel assembly.

Wherein, since the fixing portion 121 is pressed against the inner wall surface of the punching channel 1101, during the process of assembling the tool electrode 120 to the inner flushing device 110, when the fixing portion is pressed against the inner wall surface of the punching channel 1101, the tool electrode 120 will No further assembly can be performed. At this time, the staff can know whether the tool electrode 120 is assembled in place.

It should be noted here that a threaded structure can be adopted between the tool electrode 120 and the inner flushing device 110, which is simple and easy to implement.

It should be noted here that the clamping structure 130 may be implemented by a clamping jaw structure.

In the embodiment of the present application, the processing device 100 further includes an outer punching nozzle, which is configured to receive flushing liquid from the outside to flush the outer surface of the tool electrode 120 and/or the working surface. In this way, the composite structure device can simultaneously perform the flushing mode of the inner flushing liquid and the outer flushing liquid, the flushing mode of the inner flushing liquid, and the flushing mode of performing the outer flushing liquid and the flushing mode of stopping the flushing liquid at the same time.

In the actual operation of arc machining, there are many working conditions: the material of the workpiece 400 to be processed is different, resulting in different speeds of the eroded particles; due to the different structures on the workpiece 400 that need to be processed, the locations of the eroded particles are different Because of the different purposes of the workpiece 400, the quality requirements for the processed surface of the workpiece 400 are also different, and the flow field of the flushing liquid has an effect on the arc, thereby affecting the processing quality of the surface of the workpiece 400. The traditional arc machining control method has a single flushing mode, which cannot cope with complex working conditions, making it difficult to guarantee the processing quality. Especially in the process of arc micro-explosion processing, the existing processing methods usually only have an internal flushing liquid mode, and the intensity of the flushing liquid cannot meet the requirements of arc micro-explosion processing for long-term stable work. The technical solution of the application has a variety of flushing modes, can cope with more working conditions, has the advantage of a wide range of applications, and is also more conducive to improving the flushing effect of the flushing liquid on the eroded particles, ensuring the efficiency and stability of processing, In addition, the short circuit of the electrode is avoided, and the processing quality of the workpiece 400 can be improved.
