[ detailed description ] embodiments
In order to make the technical problems, technical solutions and advantageous effects solved by the present application more clear and obvious, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The adaptive milling composite tool shown in fig. 1-5 comprises a tool apron 1, a plurality of flexible electrodes 2 arranged on the peripheral side of the tool apron 1 at intervals, and a plurality of tools 3 alternately arranged on the peripheral side of the tool apron 1 at intervals with the flexible electrodes 2, wherein a discharge surface 21 is formed on one side of the flexible electrodes 2 opposite to a workpiece surface to be processed, and the discharge surface 21 can deform under the action of external force to adapt to the radian of the surface to be processed, specifically, the flexible electrodes 2 are made of foam copper. According to the self-adaptive milling compound tool, the foam copper with good conductivity, ductility and flexibility is adopted as the flexible electrode 2, so that the shape of the discharge surface of the flexible electrode can be timely corrected in the machining process of different technological parameters while the good discharge efficiency is achieved, the discharge surface can be self-adaptive to the radian of the surface to be machined, and the workpiece is prevented from being scratched.
Specifically, the pore size of the copper foam is as follows: 0.1mm-1.5mm, and the porosity is not less than 95%. Preferably, the pore size of the copper foam may be 0.1mm, 0.5mm, 1mm or 1.5 mm. Accordingly, the copper foam has a porosity of 95%, 96%, 97% or 98%. The value is reasonable, the foam copper adopting the parameters is high in softness and strong in self-adaptive capacity, the surface of a workpiece is prevented from being scratched when the foam copper is in contact with the workpiece, and the processing quality of a processed surface of the workpiece is improved.
Further, as a preferred embodiment of the present invention but not limited thereto, the flexible electrode 2 is fan-shaped, and the central angle of the flexible electrode 2 is: 100 ° -110 °, preferably, the central angle of the flexible electrode 2 is: 105 deg.. The flexible electrode 2 is in a fan shape, so that the discharge area is increased, and the discharge power and the discharge efficiency are improved.
Further, as a preferred embodiment of the present invention, but not limited thereto, the tool 3 is formed with a first cutting edge 31 and a second cutting edge 32, the first cutting edge 31 extends in the axial direction of the holder 1 and protrudes from the upper side surface of the holder 1, and the second cutting edge 32 extends in the radial direction of the holder 1 and protrudes from the outer peripheral side of the holder 1. This setting is convenient for the installation and the dismantlement of cutter 3, and the setting of a plurality of cutting edges can improve the flexibility ratio that cutter 3 used.
Further, as a preferred embodiment of the present invention, but not limited thereto, the holder 1 is formed with a mounting hole 10 into which the flexible electrode 2 is inserted. This arrangement can improve the stability of the assembly of the flexible electrode 2 and prevent the flexible electrode 2 from loosening and scattering.
Since the flexible electrode 2 is fitted in the mounting hole 10, the first cutting edge 31 protrudes from the upper side surface of the holder 1 in the axial direction of the holder 1, and the second cutting edge 32 protrudes from the peripheral side of the holder 1 in the radial direction of the holder 1. This will cause that the softened surface formed on the surface to be machined of the workpiece by the discharge surface 21 and the cutting surface formed on the surface to be machined of the workpiece by the tool 3 cannot be completely overlapped, so that the un-softened part of the surface to be machined fails to be cut, and the machining effect of the workpiece is affected.

Specifically, the two ends of the tool 3 in the axial direction of the tool holder 1 are an a end and a B end, respectively, the two ends of the discharge surface 21 in the axial direction of the tool holder 1 are an a 'end and a B' end, respectively, and the adjustment assembly 4 makes the a end level with the a 'end and the B end level with the B' end.

The structure is simple and compact, and the fine adjustment effect is good.
Accordingly, the mounting hole 10 is opened on the outer peripheral side of the holder 1, and the side of the flexible electrode 2 where the discharge surface 21 is formed protrudes from the notch of the mounting hole 10 and extends upward in the axial direction of the holder 1. As can be seen, the upper end surface of the flexible electrode 2 is flush with the upper side surface of the holder 1. This arrangement can shorten the displacement amount that adjusting part 4 adjusted, reduces the degree of difficulty of adjusting.
Of course, in the above embodiment, the specific structure of the adjusting assembly 4 is shown when the mounting hole 10 is opened on the outer peripheral side of the holder 1 and the discharge surface 21 is protruded on the outer peripheral side of the holder 1.

At this time, one side of the flexible electrode 2, where the discharge surface 21 is formed, protrudes from the upper side surface of the tool apron 1, and the adjusting assembly 4 drives the discharge surface 21 to move along the radial direction of the tool apron 1, so that two ends of the discharge surface 21 in the radial direction of the tool apron 1 and two ends of the second blade 32 in the radial direction of the tool apron 1 are located in a concentric circle, thereby realizing the superposition of a softened surface and a cutting surface and avoiding cutting failure. Specifically, two ends of the tool 3 in the radial direction of the tool holder 1 are a C end and a D end, two ends of the discharge surface 21 in the radial direction of the tool holder 1 are a C 'end and a D' end, respectively, and the adjusting component 4 makes the C end and the C 'end located on a first circle and makes the D end and the D' end located on a second circle, where the first circle and the second circle are concentric circles.
Correspondingly, the adjusting assembly 4 includes an elastic member 41 for elastically pushing the flexible electrode 2 along the radial direction of the tool holder 1, and an adjusting rod 42 for adjusting the pushing force of the elastic member 41, wherein the elastic member 41 is made of rubber, and the adjusting rod 42 is made of a bolt. The structure is simple and compact, and the fine adjustment effect is good.
Further, as a preferred embodiment of the present invention, but not limited thereto, the flexible electrode 2 and the elastic member 41 are stacked in the mounting hole 10 and are tightly fitted to the mounting hole 10, and the adjusting rod 42 is sequentially inserted through the tool holder 1, the flexible electrode 2 and the elastic member 41. As can be seen, the adjustment bar 42 is located on the side away from the discharge surface 21. The structure is simple and compact, and the fine adjustment effect is good.
Further, as a preferred embodiment of the present invention, but not limited thereto, the tool apron 1 includes a tool pan 11 and a support frame 12 forming the mounting hole 10 with the tool pan 11, and the flexible electrode 2 and the elastic member 41 are connected to the support frame 12 and located in the mounting hole 10. The support frame 12 is detachably connected with the tool apron 1 and can move relative to the tool pan 11 to adjust the distance between the flexible electrode 2 and the surface of the workpiece to be processed. Through the arrangement, the distance between the flexible electrode 2 and the surface to be processed of the workpiece is larger than or equal to zero, and the surface to be processed of the workpiece can be cleaned while gap discharge is realized.
Specifically, an elliptical hole 13 is formed in the cutter head 11, and a fastening piece 14 capable of moving along the elliptical hole 13 is connected to the cutter head 11 and the support frame 12. The structure is simple and compact, and the fine adjustment effect is good.

Specifically, the machine tool 100 is electrically connected with an oscilloscope 101 and a control terminal 102. Specifically, the electrolyte circulation device 300 includes a liquid storage tank 301 with an upward opening for storing electrolyte, a spraying head 303 for spraying electrolyte, and a circulation pump 302 for pumping the electrolyte in the liquid storage tank 301 to the spraying head 303, a support table (not shown) for supporting a workpiece is disposed in the liquid storage tank 301, and the spraying head 303 extends between the workpiece and the adaptive milling composite tool.

Based on the electric spark milling system applying the self-adaptive milling composite cutter, the following milling method is applied in the workpiece machining process, and the specific steps are as follows:
s1: adjusting the gap between the discharge surface and the surface to be processed of the workpiece to enable the discharge surface to interfere with the surface to be processed of the workpiece, turning off a power supply, rotating the tool apron, and enabling the discharge surface to be deformed and matched with the surface to be processed of the workpiece after contacting with the surface to be processed of the workpiece;
s2: driving the discharge surface to move, so that a softened surface formed on the surface to be processed of the workpiece by the discharge surface is superposed with a cutting surface formed on the surface to be processed of the workpiece by the cutter;
s3: adjusting the distance between the discharge surface and the surface to be processed of the workpiece to ensure that the discharge surface is not contacted with the surface to be processed of the workpiece completely or is contacted with the surface to be processed of the workpiece completely or partially, starting a power supply, rotating a tool apron, softening the surface to be processed of the workpiece through discharge of a flexible electrode, and cutting the softened surface to be processed by a milling cutter.
In step S1, the discharge surface can be matched with the surface to be processed of the workpiece, so as to avoid collision between the flexible electrode and the workpiece during processing of the workpiece.
In step S3, when the discharge surface is not in contact with the surface to be processed of the workpiece, a gap is formed between the discharge surface and the surface to be processed of the workpiece, and the flexible electrode does not discharge in contact, so that the discharge of the flexible electrode is more uniform and the discharge effect is better because the discharge surface and the surface to be processed of the workpiece are in contact matching in step S1; when the discharge surface is completely contacted with the surface to be processed of the workpiece, the flexible electrode is in contact discharge, and the discharge surface can be adjusted and deformed in time in the processing process, so that the surface to be processed of the workpiece can be uniformly softened by the electric arc, and meanwhile, the scraps can be swept away from the surface to be processed, so that the quality of the surface to be processed of the workpiece is improved; when the discharge surface is contacted with the part of the surface to be processed of the workpiece, the effect of gap discharge and the effect of contact discharge are achieved, and a cleaning effect is achieved.
When the flexible electrode 2 discharges to soften the surface of the workpiece to be processed, the spraying head 303 sprays electrolyte toward the gap formed between the workpiece and the flexible electrode 2.
