[0024] After the loading of the loading plate 6 is completed, the loading plate 6 is rotated to the left of the loading plate 6 and the loading plate 6 is rotated to the right of the loading plate 6.

[0025] As an implementation method, Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the driving member 5 includes a hydraulic cylinder 51 fixedly mounted on the movable plate 6, the output end of the hydraulic cylinder 51 is fixedly connected to the mounting seat 52, the mounting seat 52 is fixedly mounted with a guide rail frame 53, the guide rail frame 53 is slidably mounted on one side of the movable plate 6, and the electric clamp 81 is rotatably connected to the bottom of the mounting seat 52; a flip cylinder 54 is horizontally mounted on one side of the mounting seat 52, the output end of the flip cylinder 54 is movably connected to a connecting plate 55, and the other end of the connecting plate 55 is fixedly connected to one end of the electric clamp 81.

[0026] In this embodiment, on the feed conveyor 2, the electric guide rail 8 is used to drive the movable plate 6 to move horizontally. The hydraulic cylinder 51 inside the driving member 5 on the movable plate 6 drives the mounting seat 52 to move downward until the electric clamping claw 81 at the bottom of the mounting seat 52 contacts the drive shaft station, and then the drive shaft on the feed conveyor 2 is clamped. After clamping, the hydraulic cylinder 51 drives the mounting seat 52 upward. When it moves to the top of the anti-rust liquid tank 7, the hydraulic cylinder 51 drives the mounting seat 52 to move downward until the electric clamping claw 81 at the bottom of the mounting seat 52 contacts the drive shaft station. After being immersed in the interior of the rust-proof liquid tank 7, the hydraulic cylinder 51 drives the electric clamping jaw 81 at the bottom of the mounting seat 52 to move upward, and drives the movable plate 6 to move above the discharge conveyor 3 through the electric guide rail 8, completing the transfer of the entire drive shaft; when the electric clamping jaw 81 moves above the rust-proof liquid tank 7, the turning cylinder 54 is started, pushing one end of the connecting plate 55, and the other end of the connecting plate 55 drives the electric clamping jaw 81 to rotate 90°, so that the electric clamping jaw 81 is perpendicular to the mounting seat 52, so that it is better immersed in the rust-proof liquid tank 7, ensuring the immersion effect.

[0027] As an implementation method, Figure 2 and Figure 4 As shown, a vertical rod 56 is fixedly mounted on the top of the mounting seat 52 , a fixing seat 57 is sleeved on the outside of the vertical rod 56 , and the fixing seat 57 is fixedly mounted on the movable plate 6 .

[0028] The guide rail frame 53 is arranged in a mirror-symmetrical manner with respect to the center of the mounting seat 52 , and the guide rail frame 53 is an I-shaped structure.

[0029] In this embodiment, the mounting seat 52 moves vertically downward under the action of the guide rail frame 53 and the vertical rod 56 to ensure the up and down movement path of the mounting seat 52. When the mounting seat 52 moves, the vertical rod 56 moves in the fixed seat 57.

[0032] In this embodiment, when the workpiece is large in size, the liquid level height of the internal rust-proof liquid is different, the resistance of the liquid level sensor 10 will usually become smaller, and the current passed into the electromagnet 15 will be large. In the process of the electric guide rail 8 driving the movable plate 6 to reset, the movable plate 6 moves from the rust-proof liquid tank 7 to the path of the discharge conveyor 3, and the sleeve 14 passes through the metal segment 13 in the cross bar 12. Using the principle of electromagnetic damping, the metal segment 13 inside the cross bar 12 and the magnetic field generated by the electromagnet 15 have relative resistance, thereby slowing down the moving speed of the movable plate 6 from the rust-proof liquid tank 7 to the discharge conveyor 3, and avoiding the rust-proof liquid from dripping quickly during the movement after the large workpiece is soaked.

[0033] As an implementation method, Figure 1 、 Figure 2 As shown, the anti-rust liquid tank 7 , the discharging conveyor 3 and the feeding conveyor 2 are arranged at the same height, and a collecting box 16 is provided below the anti-rust liquid tank 7 .

[0036] Working principle: When in use, the driving shaft is moved to one end of the feeding conveyor 2 through the feeding conveyor 2, and the movable plate 6 is driven to move horizontally by the electric guide rail 8. After the movable plate 6 is moved horizontally to one end close to the feeding conveyor 2, the hydraulic cylinder 51 inside the driving member 5 on the movable plate 6 drives the mounting seat 52 to move downward, and the mounting seat 52 moves vertically downward along the guide rail frame 53 and the vertical rod 56 until the electric clamping claw 81 at the bottom of the mounting seat 52 contacts the driving shaft station, clamping the driving shaft on the feeding conveyor 2. After clamping, the hydraulic cylinder 51 drives the mounting seat 52 upward, and the electric guide rail 8 drives the movable plate 6 to move horizontally. The movable plate 6 starts to reset; in the process of the movable plate 6 moving toward the discharge conveyor 3, until it is above the anti-rust liquid tank 7, the flip cylinder 54 is started, pushing one end of the connecting plate 55, and the other end of the connecting plate 55 drives the electric clamp 81 to rotate 90 degrees, so that the electric clamp 81 is perpendicular to the mounting seat 52. At this time, the hydraulic cylinder 51 drives the mounting seat 52 to move downward until the electric clamp 81 at the bottom of the mounting seat 52 is immersed in the interior of the anti-rust liquid tank 7, ensuring that the drive shaft workpiece is completely immersed in the anti-rust liquid tank 7. The hydraulic cylinder 51 drives the electric clamp 81 at the bottom of the mounting seat 52 to move upward, and then passes through the electric guide rail 8 with The movable plate 6 moves to the top of the discharge conveyor 3; finally, the reversing cylinder 54 drives the electric clamping claw 81 to reverse and reset. After resetting, the hydraulic cylinder 51 drives the mounting seat 52 downward, and the electric clamping claw 81 releases the drive shaft workpiece and transports it through the discharge conveyor 3. It is suitable for large-scale drive shaft unloading and rust prevention operations, and timely immersion of rust inhibitors to improve qualified products; during the rust prevention process, when the electric clamping claw 81 at the bottom of the mounting seat 52 is immersed in the interior of the rust prevention liquid tank 7, due to the different sizes of the drive shaft workpieces, when the workpiece volume is large, the liquid level height of the internal rust prevention liquid is different, and the resistance value of the liquid level sensor 10 is usually It will become smaller, and the current passed into the electromagnet 15 is large. In the process of the electric guide rail 8 driving the movable plate 6 to reset, the movable plate 6 moves from the anti-rust liquid tank 7 to the path of the discharge conveyor 3, and the sleeve 14 passes through the metal segment 13 in the cross bar 12. By utilizing the principle of electromagnetic damping, the metal segment 13 inside the cross bar 12 and the magnetic field generated by the electromagnet 15 have relative resistance, thereby slowing down the moving speed of the movable plate 6 from the anti-rust liquid tank 7 to the discharge conveyor 3, increasing the time that the drive shaft immersed in the anti-rust liquid is above the anti-rust liquid tank 7, avoiding the dripping of the anti-rust liquid during movement, preventing excessive loss of anti-rust liquid, and having a high recycling rate.
