[0031] Referring to Figures 1 to 4 The electrode lead-in structure of the first aspect embodiment of the utility model, comprising: sealing piece 210, for connecting with cavity 400;Main shaft 100, a plurality of wire 300 holes through which wire 300 passes are opened, the main shaft 100 passes through the sealing piece 210, the main shaft 100 is slidably connected with the sealing piece 210, a sealing ring is arranged between the main shaft 100 and the sealing piece 210, one end of the main shaft 100 is provided with the first adapter plate 110 through which the wire 300 passes, and the first adapter plate 110 is sealed between the end of the main shaft 100, the other end of the main shaft 100 is provided with the adapter component 120 through which the wire 300 passes, and the adapter component 120 is sealed between the end of the main shaft 100.

[0032] The wire 300 passes through the wire 300 hole of the main shaft 100, and the wire 300 is fixed on the main shaft 100 by the first adapter plate 110 and the adapter component 120 at both ends of the main shaft 100, so that the wire 300 moves synchronously with the main shaft 100, avoids being pulled off, protects the wire 300, and the gap between the first adapter plate 110 and the adapter component 120 and the wire 300 is sealed, and the wire 300 hole at both ends of the main shaft 100 is sealed, in addition, the sealing ring keeps the sealing between the main shaft 100 and the sealing piece 210, when the main shaft 100 moves, the sealing performance between the main shaft 100 and the sealing piece 210 is guaranteed, the electrode wire 300 is protected while the sealing performance is guaranteed, and the electrode wire 300 is prevented from being pulled off.

[0033] It can be understood that, referring to Figure 2 And Figure 3The sealing ring comprises a plurality of first rubber rings 211 and a plurality of second rubber rings 212. The plurality of first rubber rings 211 are arranged on both sides of the plurality of second rubber rings 212. The first rubber ring 211 protrudes outwardly of the sealing member 210 and forms a sealing portion 213. The sealing portion 213 abuts against the main shaft 100. When the main shaft 100 moves, the sealing portion 213 is always in close contact with the main shaft 100, thereby reducing the influence of the movement of the main shaft 100 on the first rubber ring 211, ensuring the sealing between the sealing member 210 and the main shaft 100. The second rubber ring 212 abuts against the main shaft 100, further ensuring the sealing between the main shaft 100 and the sealing member 210. The plurality of second rubber rings 212 cooperate to improve the sealing performance of the sealing member 210.

[0034] It can be understood that, with reference to Figure 3 The sealing member 210 is provided with a plurality of positioning grooves 214. The first rubber ring 211 and the second rubber ring 212 are arranged in the positioning grooves 214. By arranging the first rubber ring 211 and the second rubber ring 212 in the positioning grooves 214, the first rubber ring 211 and the second rubber ring 212 are prevented from moving with the main shaft 100 when the main shaft 100 moves, thereby preventing the first rubber ring 211 and the second rubber ring 212 from failing.

[0035] It can be understood that, with reference to Figure 1 The first adapter plate 110 is provided with a connecting screw 111. The connecting screw 111 is screwed with the main shaft 100 through the first adapter plate 110, and the connecting screw 111 drives the first adapter plate 110 to be in close contact with the end of the main shaft 100. By tightening the connecting screw 111, the first adapter plate 110 is in close contact with the end of the main shaft 100, thereby sealing the space between the first adapter plate 110 and the end of the main shaft 100.

[0036] It can be understood that, with reference to Figure 2 and Figure 4 The adapter component 120 comprises a flange 121 and a second adapter plate 122 through which the wire 300 passes. The end of the main shaft 100 is provided with a connecting portion 130. The flange 121 is tightly connected with the connecting portion 130, and the flange 121 and the connecting portion 130 cooperate to clamp the second adapter plate 122. The second adapter plate 122 is used to fix the wire 300, and the space between the second adapter plate 122 and the wire 300 is kept sealed. The second adapter plate 122 is installed on the end of the main shaft 100 through the flange 121. By locking the second adapter plate 122 on the connecting portion 130 of the main shaft 100 through the flange 121, the sealing is ensured, and the disassembly is facilitated.

[0037] Specifically, with reference to Figure 4The flange 121 has a first snap-fit ​​portion 124 protruding inward, and the second adapter plate 122 has a second snap-fit ​​portion 125 protruding outward. The second snap-fit ​​portion 125 snaps between the first snap-fit ​​portion 124 and the connecting portion 130. When the flange 121 is tightened, the first snap-fit ​​portion 124 drives the second snap-fit ​​portion 125, causing the second snap-fit ​​portion 125 to fit tightly against the connecting portion 130, ensuring a seal between the second adapter plate 122 and the connecting portion 130.

[0038] Understandably, referring to Figure 4 A third rubber ring 123 is provided between the second adapter plate 122 and the connecting part 130. The second snap-fit ​​part 125 and the connecting part 130 cooperate to compress the third rubber ring 123. When the first snap-fit ​​part 124 drives the second snap-fit ​​part 125 to move toward the connecting part 130, the second snap-fit ​​part 125 presses the third rubber ring 123, further enhancing the sealing between the second adapter plate 122 and the connecting part 130.

[0039] Understandably, referring to Figure 4 A positioning ring 126 is provided between the second adapter plate 122 and the main shaft 100. The positioning ring 126 is engaged between the second adapter plate 122 and the connecting part 130. The positioning ring 126 protrudes radially to form a positioning part 127, which matches the third rubber ring 123 and abuts against it. Both the second adapter plate 122 and the connecting part 130 are provided with locking positions. The positioning ring 126 is positioned between the second adapter plate 122 and the main shaft 100 by locking positions. Then, the positioning part 127 cooperates with the flange 121 to limit the position of the third rubber ring 123, preventing the third rubber ring 123 from being squeezed and deviating, further improving the sealing performance.

[0040] The discharge device of the second aspect of this utility model includes the electrode introduction structure of the first aspect of this utility model. A wire 300 passes through a wire 300 hole in the main shaft 100. The wire 300 is fixed to the main shaft 100 by a first adapter plate 110 and an adapter component 120 at both ends of the main shaft 100, allowing the wire 300 to move synchronously with the main shaft 100. This prevents the wire 300 from being broken and protects it. Furthermore, the gaps between the first adapter plate 110 and the adapter component 120 and the wire 300 are sealed, simultaneously sealing the wire 300 holes at both ends of the main shaft 100. In addition, a sealing ring maintains a seal between the main shaft 100 and the sealing member 210. When the main shaft 100 moves, the sealing performance between the main shaft 100 and the sealing member 210 is ensured, achieving both sealing performance and protection of the electrode wire 300, preventing it from being torn.

[0041] Understandably, referring to Figure 1The discharge device includes a cavity 400. The seal 210 is provided with fasteners 221 and bolts 222. The fasteners 221 are snapped into the seal 210, and the bolts 222 pass through the fasteners 221 and are threaded into the cavity 400 to install the seal 210 onto the cavity 400 and position the spindle 100. The cavity 400 has a clearance hole that matches the spindle 100 to reduce the gap between the spindle 100 and the clearance hole. A fourth rubber ring 223 is provided between the seal 210 and the outer wall of the cavity 400. The fourth rubber ring 223 surrounds the clearance hole, and the seal 210 presses the fourth rubber ring 223 tightly to improve the sealing performance between the seal 210 and the cavity 400 and prevent the vacuum degree inside the cavity 400 from decreasing.
