The staff places the three-phase motor housing 104 on the workbench 101. When the placement is completed, the staff starts the driving component to drive the friction ball 2028 to move, so as to align the placed three-phase motor housing 104. At the same time, the friction ball 2028 can enter the inner cavity of the three-phase motor housing 104 to position the three-phase motor housing 104. At the same time, the driving component can also drive the first limit block 2034 and the second limit block 2035 to position the outer wall of the aligned three-phase motor housing 104, thereby ensuring that the three-phase motor housing 104 will not move when drilling.

[0037] like Figures 1 to 4 and Figure 6 as well as Figure 7 As shown, in a specific embodiment, the workbench 101 is also provided with conveying components 102 around it, and the four conveying components 102 are symmetrical to each other. A plurality of rectangular slots 1012 are also provided above the workbench 101, and each rectangular slot 1012 is respectively provided on both sides of the circular slot 1011, and the two rectangular slots 1012 are symmetrical to each other. In this setting, the opening position of the rectangular slot 1012 and the setting position of the conveying component 102 are determined, so that when the drilling of the three-phase motor housing 104 is completed, the three-phase motor housing 104 can be pushed to unload the three-phase motor housing 104, which avoids the need for manual handling to a certain extent.

[0038] like Figure 3 and Figure 4 as well as Figures 6 to 8As shown in the figure, further, the driving assembly includes a servo motor 201. The servo motor 201 is arranged inside the workbench 101. A rotating rod 2011 is fixedly connected to the output end of the servo motor 201. A turntable 2012 is fixedly connected above the rotating rod 2011.

Each pair of the rotating rods 2027 is symmetric with each other. Friction balls 2028 are arranged on the opposite side walls of each pair of the rotating rods 2027. In this setting, the specific installation position of the friction balls 2028 is determined, ensuring that the friction balls 2028 can move vertically.

[0040] As Figure 3 and Figure 4 and Figures 6 to 8 As shown in the figure, further, positioning plates 203 are fixedly connected to the opposite side walls of the four connecting pieces 2022 in pairs. The four positioning plates 203 are symmetric with each other in pairs. Telescopic rods 2031 are arranged at the bottoms of the four positioning plates 203. The bottoms of the four telescopic rods 2031 are arranged at the bottom inside the workbench 101. L-shaped connecting rods 2032 are fixedly connected to the two side walls of the four positioning plates 203. Each pair of the L-shaped connecting rods 2032 is symmetric with each other. In this setting, the installation positions of the telescopic rods 2031, the positioning plates 203 and the L-shaped connecting rods 2032 are determined, ensuring that the positioning plates 203 can move vertically.

[0041] As Figure 3 and Figure 4 and Figures 6 to 8As shown in the figure, further, a placing rod 2033 is arranged above each L-shaped connecting rod 2032. Each pair of placing rods 2033 is symmetric with each other. A first limiting block 2034 and a second limiting block 2035 are respectively arranged between each pair of placing rods 2033.

[0042] Embodiment 2:

[0043] Based on Embodiment 1, the difference from this embodiment is: As Figures 1 to 8 shown, for an integrated drilling and tapping device for processing marine three-phase motors, a rotating rod 301 is further fixedly installed above the rotating rod 2011. The rotating rod 301 passes through the workbench 101 movably, and a rotating disk 3011 is fixedly installed on the rotating rod 301. In this setting, it is ensured that the rotating disk 3011 can rotate.

[0044] As Figures 1 to 5 shown, in the specific implementation, a special-shaped track 3012 is arranged on the rotating disk 3011. Four moving sliders 3013 distributed in a circular pattern are slidably arranged above the special-shaped track 3012. Activity rods 3014 are movably arranged above the four moving sliders 3013. In this setting, the installation positions and components of the activity rods 3014 are determined.

[0045] Embodiment 3:

[0046] Based on Embodiment 2, the difference from this embodiment is: As Figures 1 to 4 shown, for an integrated drilling and tapping device for processing marine three-phase motors, four guiding rods 3023 distributed in a circular pattern are fixedly installed at the bottom of the top plate 1031. The four guiding rods 3023 are respectively aligned with the circular notch 1011. Limiting rings 3024 are arranged at the ends of the four guiding rods 3023 away from the top plate 1031 respectively. In this setting, the installation positions of the guiding rods 3023 are determined.

[0047] As Figures 1 to 5As shown in the figure, in the specific implementation, two mutually symmetrical support rods 3021 are fixedly connected to each of the four storage boxes 3022. Each pair of support rods 3021 is symmetrical to each other. Above each pair of support rods 3021, a mounting plate 302 is fixedly connected. The four mounting plates 302 are respectively slidably connected to the guide rods 3023. On one side wall of each pair of opposite mounting plates 302, a movable rod 3014 is provided. In this setting, it is ensured that when the rotating rod 2011 rotates, it can also drive the rotating rod 301 to rotate. When the rotating rod 301 rotates, it can drive the rotating disk 3011 to rotate. Since the rotating disk 3011 is provided with a special-shaped track 3012, and four moving sliders 3013 are slidably arranged on the special-shaped track 3012, and the four moving sliders 3013 are movably provided with a movable rod 3014, and the other end of the movable rod 3014 is movably arranged on the mounting plate 302, and the mounting plate 302 is limited by the guide rod 3023, it is ensured that the moving slider 3013 will not rotate and will only move back and forth under the assistance of the special-shaped track 3012, so as to ensure that the mounting plate 302 can move vertically under the assistance of the guide rod 3023.

[0048] The implementation principle of an integrated drilling and tapping device for processing marine three-phase motors of the present invention is as follows:

[0049] First, the staff places the three-phase motor housing 104 above the circular notch 1011. When the placement is completed, the staff starts the servo motor 201, so the servo motor 201 can drive the rotating rod 2011 to rotate. Since the rotating disk 2012 is fixedly installed on the rotating rod 2011, the rotating disk 2012 can be rotated.

[0050] When the rotating disk 2012 rotates, it can drive the special-shaped track mounting ring 202 to rotate. Since the special-shaped track mounting ring 202 is slidably provided with balls 2021, and a connecting member 2022 is provided on the ball 2021, and a positioning plate 203 is provided on one side wall of the connecting member 2022. At the same time, a telescopic rod 2031 is provided at the bottom of the positioning plate 203, and the bottom of the telescopic rod 2031 is fixedly provided at the bottom of the inner cavity of the workbench 101, so it is ensured that the ball 2021 will not rotate (because the ball 2021 is arranged on the special-shaped track mounting ring 202, so when the special-shaped track mounting ring 202 rotates, at this time the ball 2021 can move vertically).

[0051] When the ball 2021 moves vertically, it can drive the connecting piece 2022 to move vertically, thereby driving the fixing piece 2023 to move vertically. When the fixing piece 2023 moves vertically, it can drive the connecting rod 2024 to move vertically. When the connecting rod 2024 moves vertically, it will be able to drive the connecting rod 2025 to move vertically, thereby being able to drive the fixing block 2026 to move vertically. Therefore, it is ensured that the friction ball 2028 can move vertically. When the friction ball 2028 exits from the circular notch 1011, at this time, the three-phase motor housing 104 can be slowly adjusted to a position concentric with the circular notch 1011 through the side wall. At the same time, when the friction ball 2028 continues to move, it can enter the inner cavity of the three-phase motor housing 104, thereby positioning the friction ball 2028;

[0052] When the connecting piece 2022 moves vertically, it can also drive the positioning plate 203 to move vertically. When the positioning plate 203 moves vertically, it will be able to drive the L-shaped connecting rod 2032 to move vertically. When the L-shaped connecting rod 2032 moves vertically, it will be able to drive the placing rod 2033 to move vertically. When the placing rod 2033 moves vertically, it will be able to drive the first limiting block 2034 and the second limiting block 2035 to move vertically. Therefore, the first limiting block 2034 and the second limiting block 2035 can pass through the rectangular notch 1012 and be located on both sides of the outer wall of the three-phase motor housing 104, thereby further positioning the three-phase motor housing 104;

[0053] When the rotating rod 2011 rotates, it can also drive the rotating rod 301 to rotate. When the rotating rod 301 rotates, it can drive the rotating disk 3011 to rotate (because a special-shaped track 3012 is provided on the rotating disk 3011, and four moving sliders 3013 are slidably arranged on the special-shaped track 3012, and a movable rod 3014 is movably arranged on the four moving sliders 3013, and the other end of the movable rod 3014 is movably arranged on the mounting plate 302, and the mounting plate 302 is limited by the guide rod 3023. Therefore, it is ensured that the moving slider 3013 will not rotate and will only move back and forth with the assistance of the special-shaped track 3012, thereby ensuring that the mounting plate 302 can move vertically with the assistance of the guide rod 3023)

[0054] When the mounting plate 302 moves vertically, it can drive the storage box 3022 to move vertically through the support rod 3021 at this time. Therefore, the storage box 3022 can enter the three-phase motor housing 104. At the same time, the staff operates the power moving assembly 1032 again, so that the drilling cutter head 1033 and the tapping cutter head 1034 can respectively carry out hole opening on the placed three-phase motor housing 104 successively (because the storage box 3022 is located in the inner cavity of the three-phase motor housing 104, it is ensured that during hole opening, the inward debris generated can be collected by the storage box 3022, thus to a certain extent avoiding the situation that the debris falls from the three-phase motor housing 104 into the inner cavity of the workbench 101). For the debris generated outside, at this time, the rectangular notch 1012 is blocked by the first limit block 2034 and the second limit block 2035, so it is ensured that the debris will not fall into the inner cavity of the workbench 101.
