[0018] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a device for automatically unloading and rust-proofing a drive shaft comprises a frame 1, a feeding conveyor 2 is detachably mounted on one side of the frame 1, and a discharging conveyor 3 is connected to the frame 1, an anti-rust liquid tank 7 is arranged between the feeding conveyor 2 and the discharging conveyor 3, the anti-rust liquid tank 7 is mounted on the frame 1, and a liquid level sensor 10 is arranged inside the anti-rust liquid tank 7; an elevated frame 4 is fixedly mounted on one side of the frame 1, an electric guide rail 8 is fixedly mounted on the top of the elevated frame 4, a moving plate 6 is slidably mounted on the electric guide rail 8, a driving member 5 is arranged on one side of the moving plate 6, an electric clamp 81 is arranged inside the driving member 5, and the driving member 5 is used to drive the driving shaft from the feeding conveyor 2 through the anti-rust liquid tank 7 to the discharging conveyor 3; a cross bar 12 is fixedly mounted on the top of the electric guide rail 8, the moving plate 6 is sleeved on the outside of the cross bar 12, and a damping member 11 is arranged inside the moving plate 6, and the damping member 11 is electrically connected to the liquid level sensor 10.

[0020] After the rust prevention is finished, the moving plate 6 is moved to the top of the discharging conveyor 3 by the electric guide rail 8, and the moving plate 6 is moved to the top of the discharging conveyor 3 by the electric clamp 81 in the driving member 5. After the rust prevention is finished, the moving plate 6 is moved to the top of the discharging conveyor 3 by the electric clamp 81 in the driving member 5. After the rust prevention is finished, the moving plate 6 is moved to the top of the discharging conveyor 3 by the electric guide rail 8, and the discharging conveyor 3 is used for transportation. It is suitable for large-scale rust prevention of driving shaft unloading, timely immersion of rust inhibitor, and improvement of qualified products. At the same time, during the rust prevention treatment process, due to the different sizes of the driving shaft workpieces, when the workpiece volume is large, the moving speed of the moving plate 6 from the rust prevention liquid tank 7 to the discharging conveyor 3 is slowed down, and the time of the driving shaft immersed in the rust prevention liquid above the rust prevention liquid tank 7 is increased, so as to avoid the dripping of the rust prevention liquid during the movement, and to prevent the excessive loss of the rust prevention liquid, and the recycling rate is high.

[0021] 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 a mounting seat 52, a guide rail frame 53 is fixedly mounted on the mounting seat 52, 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.

[0022] In this embodiment, on the feed conveyor 2, the electric guide rail 8 is used to drive the moving plate 6 to move horizontally, and the hydraulic cylinder 51 inside the driving member 5 on the moving 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 driving shaft station, and then the driving shaft on the feed conveyor 2 is clamped. After clamping, the hydraulic cylinder 51 drives the mounting seat 52 upward and moves to the top of the anti-rust liquid tank 7. At this time, 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 driving shaft station. After being immersed in the interior of the anti-rust 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 to the top of 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 to the top of the anti-rust liquid tank 7, the turning cylinder 54 is started to push 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 can be better immersed in the anti-rust liquid tank 7 and ensure the immersion effect.

[0023] 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 moving plate 6 .

[0024] 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.

[0025] 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 fixing seat 57.

[0026] As an implementation method, Figure 3 , Figure 4 , Figure 5 As shown, the damping member 11 includes a metal section 13 arranged inside the cross bar 12, and the metal section 13 is arranged near the top of the anti-rust liquid tank 7; a sleeve 14 is fixedly installed inside the movable plate 6, and the sleeve 14 is sleeved on the outside of the cross bar 12, and an electromagnet 15 is arranged inside the sleeve 14, and the electromagnet 15 corresponds to the cross bar 12, and the electromagnet 15 is electrically connected to the liquid level sensor 10.

[0027] The length of the metal segment 13 is one third of the length of the crossbar 12 , and the electromagnet 15 is a U-shaped structure.

[0028] In this embodiment, when the workpiece is large in size, the liquid level height of the internal rust-proof liquid is different, the resistance value of the liquid level sensor 10 usually becomes 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 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. 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 rust-proof liquid tank 7 to the discharge conveyor 3, thereby preventing the rust-proof liquid from dripping quickly during the movement after the large workpiece is soaked.

[0029] 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 arranged below the anti-rust liquid tank 7 .

[0030] Among them, support chains are arranged between the movable plate 6 and the electric guide rail 8 , and between the mounting seat 52 and the movable plate 6 .

[0031] In this embodiment, the drive shaft workpiece on the feed conveyor 2 is immersed in the anti-rust liquid tank 7 and then moved to the discharge conveyor 3 through the drive member 5. The same height setting is convenient for transportation. At the same time, the setting of the collection box 16 is convenient for collecting dripping anti-rust liquid during the transportation process.

[0032] 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 moving plate 6 is driven to move horizontally by the electric guide rail 8. After the moving 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 moving 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, and then the driving shaft on the feeding conveyor 2 is clamped. After clamping, the hydraulic cylinder 51 drives the mounting seat 52 upward, and the electric guide rail 8 drives the moving plate 6 to start resetting; In the process of the moving plate 6 moving toward the discharge conveyor 3, when it is above the anti-rust liquid tank 7, the turning cylinder 54 is started to push 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 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 drives the moving plate 6 to move above the discharge conveyor 3 through the electric guide rail 8; Finally, the flip cylinder 54 drives the electric clamp 81 to flip and reset. After resetting, the hydraulic cylinder 51 drives the mounting seat 52 downward, and the electric clamp 81 releases the drive shaft workpiece, which is transported through the unloading conveyor 3. It is suitable for large-scale drive shaft unloading and rust prevention operations, and timely immersion of rust inhibitors can improve qualified products. During the rust prevention process, when the electric clamp 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 workpiece, 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 usually becomes smaller, and the electromagnet is passed through The current of 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. 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 driving shaft immersed in the anti-rust liquid is above the anti-rust liquid tank 7, avoiding the dripping of the anti-rust liquid during the movement, preventing the loss of excessive anti-rust liquid, and achieving a high recycling rate.
