[0022] Figure 1 The three-dimensional diagram of the base EDM tooling of the utility model is shown in the figure. The base 1, the front pressing plate 2 and the rear pressing plate 3 are shown.

[0023] like Figure 1-4 As shown, the base EDM tooling is used to clamp the base 4 of the CNC cutting machine vibration knife seat, the front end of the CNC cutting machine vibration knife seat base 4 is cylindrical, and the rear end of the CNC cutting machine vibration knife seat base 4 is semi-cylindrical. The front pressing plate 2 and the rear pressing plate 3 cooperate to fix the CNC cutting machine vibration knife seat base 4 on the base 1.

[0024] The base 1 is L-shaped and is an integrated structure consisting of a bottom block 101 and a side block 102, wherein a plurality of mounting grooves are provided on the base 1 for placing a vibration tool holder base 4 of a CNC cutting machine, and the mounting grooves are composed of an arc groove 5 provided on the upper end surface of the bottom block 101 and a through hole 6 provided on the side block 102, and the arc groove 5 is connected to the through hole 6.

[0025] When in use, the front end of the CNC cutting machine vibration knife base base 4 extends from the arc groove 5 into the through hole 6 of the side block 102, and the rear end of the CNC cutting machine vibration knife base base 4 is located at the arc groove 5 on the upper end surface of the base 1.

[0026] The front pressing plate 2 is arranged on the front surface of the side block 102 and is used to limit the vibration knife seat base 4 of the CNC cutting machine from sliding out of the through hole 6 .

[0027] The two sides of the arc groove 5 are fixedly connected to the rear pressing plate 3, and the two side edges of the rear pressing plate 3 are respectively used to press on the top of the vibration knife seat base 4 of the CNC cutting machine.

[0028] Specifically, a threaded hole is provided between two adjacent through holes 6 on the front end surface of the side block 102 for fixing the front pressure plate 2 to the base 1 via bolts to prevent the vibration tool holder base 4 of the CNC cutting machine from sliding out of the through hole 6 of the side block 102 .

[0029] In this embodiment, the two through holes 6 share a front pressure plate 2, and the front pressure plate 2 is provided with double side wings, and a groove is opened in the middle of the double side wings for the bolts to pass through, and the double side wings respectively cover a through hole 6.

Except for the rear pressure plates 3 at both ends, the others are in a cross shape, and the cross-shaped rear pressure plates 3 can press the CNC cutting machine vibration knife seat base 4 on both sides.

[0031] Furthermore, in order to avoid mutual influence between the threaded holes 7 of the bottom block 101 and the side block 102, the threaded holes 7 provided on the bottom block 101 are inclined holes, the heads of the bolts are close to the side block 102, and the tails of the bolts are far away from the side block 102. In this embodiment, the angle of the inclined hole is 10°.
