Description

Technical Field

[0001] The utility model relates to the technical field of passivation devices, in particular to a metal part passivation device. Background Art

[0002] Passivation refers to the process of oxidizing a metal with a strong oxidant or electrochemical method to make the surface inactive, that is, passivation. It is a method of converting the metal surface into a state that is not easily oxidized, thereby slowing down the corrosion rate of the metal. Nowadays, when metal parts are passivated, in order to ensure that all metal parts can fully contact the passivation liquid in the passivation tank, a horizontally placed loading cylinder is used. The loading cylinder is then rotated to repeatedly move the metal parts in the loading cylinder to make the metal parts fully contact with the passivation liquid, thereby improving the passivation effect on the metal parts. However, when placing the metal parts into the loading cylinder, the staff needs to manually open the sealing cover on the loading cylinder and then place the metal parts into the loading cylinder. After the passivation of the metal parts is completed, the staff still needs to manually open the sealing cover on the loading cylinder to discharge the metal parts. The operation process is cumbersome and can easily cause the staff's arms or clothes to be contaminated with passivation liquid, causing irritation to the staff's skin. Utility Model Content

[0004] In order to solve the above technical problems, the present invention specifically adopts the following technical solutions:

[0005] A metal part passivation device comprises a base plate, a passivation tank is fixed on the top of the base plate, a U-shaped fixed frame is provided in the passivation tank, two front-to-back symmetrical movable plates are provided in the passivation tank, a loading cylinder with a perforation on the surface and located inside the fixed frame is rotatably connected between the two movable plates, an opening is provided at the bottom of the loading cylinder, and a No. 1 motor for driving the loading cylinder is provided on one movable plate; a connecting cylinder with a top located in the opening is provided below the loading cylinder, the bottom of the connecting cylinder contacts the inner side of the fixed frame, an L-shaped rod passing through the bottom of the loading cylinder is fixed at both ends of the connecting cylinder, a spring is fixed to the top of the L-shaped rod through the connecting plate, and a fixed plate connected to the inner wall of the loading cylinder is fixed to the other end of the spring; a top plate is provided above the passivation tank, and an electric telescopic rod for driving the movable plate to rise and fall is provided on the top plate.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] First, make the opening on the loading cylinder be located at the top of the loading cylinder. At this time, the spring is in an uncompressed state, and the connecting cylinder is located above the opening, so that the staff can put the metal parts into the loading cylinder easily. When all the metal parts are placed in the loading cylinder, the electric telescopic rod can be started to drive the movable plate to move downward into the passivation tank, so that the metal parts in the loading cylinder are located in the passivation liquid. Then start the No. 1 motor to rotate the loading cylinder. When the opening is at an angle above the loading cylinder, the connecting cylinder enters the fixed frame. When the connecting cylinder contacts the inner wall of the fixed frame, the connecting cylinder can squeeze the spring through the L-shaped rod, and the connecting cylinder enters the opening to seal the opening.

A screw rod 84 is threaded through the slider 83. A second motor 85 is fixed to the top plate 8 for driving the screw rod 84. A connecting block 86 is fixed to the slider 83 and slidably connected to the top of the top plate 8. The second motor 85 is a servo motor. The main body of the second motor 85 is fixed to the top plate 8. The rotating shaft of the second motor 85 is fixed to one end of the screw rod 84. When the second motor 85 is started to rotate the screw rod 84, the slider 83 can move horizontally within the opening in the top plate 8. The movable block 82 can drive the electric telescopic rod 9 to move horizontally, and the electric telescopic rod 9 can drive the movable plate 3 to move. The connecting block 86 can increase the stability of the connection between the slider 83 and the top plate 8.

[0018] like Figure 1 、 Figure 4 and Figure 6 As shown, the number of the electric telescopic rods 9 is two, and the two electric telescopic rods 9 are symmetrically distributed front to back. The telescopic end of the electric telescopic rod 9 is fixed with an L-shaped hanging plate 91 through a fixed block. Two groups of left-right symmetrical limiting plates 92 are fixed to the bottom of the inner side of the hanging plate 91. The number of each group of limiting plates 92 is two, and the two limiting plates 92 are symmetrically distributed left and right; the two movable plates 3 are fixed with mounting plates 7 on the opposite sides, and the two mounting plates 7 are located between the two hanging plates 91. Two left-right symmetrical fixing rods 71 ​​are fixed on the mounting plate 7, and the two fixing rods 71 ​​correspond to the two groups of limiting plates 92 respectively. The second motor 85 is turned off, and the second motor 85 is turned off. Figure 6When the fixing rod 71 contacts the bottom of the inner side of the hanging plate 91, the fixing rod 71 can drive the mounting plate 7 to move upward, and the mounting plate 7 is fixed to the movable plate 3 by screws and nuts. The mounting plate 7 can drive the movable plate 3 to move upward, so that the loading cylinder 4 is moved outside the passivation tank 2.

[0019] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a rotating rod 31 is rotatably connected between the two movable plates 3. An upper pulley 32 is fixed to the rotating rod 31. A lower pulley 55 is fixed to one end of the loading drum 4. A transmission belt 6 is provided between the two movable plates 3. The upper pulley 32 and the lower pulley 55 are connected by the transmission belt 6. The rotating shaft of the No. 1 motor 34 is fixed to one end of the rotating rod 31. A battery 35 is fixed to the movable plate 3. The main body of the No. 1 motor 34 is fixed to one of the movable plates 3 via a bearing block. The battery 35 can supply power to the No. 1 motor 34. When the No. 1 motor 34 is started, it drives the rotating rod 31 to rotate. The upper pulley 32 on the rotating rod 31 drives the transmission belt 6 to operate. After the transmission belt 6 drives the lower pulley 55 to rotate, the loading drum 4 can be rotated, thereby facilitating the repeated movement of the metal parts in the loading drum 4.

[0020] like Figure 1 and Figure 4 As shown, two supporting rods 36 are fixed to the opposite sides of the two movable plates 3, two supporting blocks 25 are fixed to the top of the passivation tank 2, and a placement frame 26 is fixed to the top of the supporting block 25. The supporting rods 36 are located inside the placement frame 26. The placement frame 26 is U-shaped, so that after the supporting rods 36 enter the placement frame 26, the placement frame 26 can limit the supporting rods 36 so that the loading cylinder 4 is located in the passivation tank 2; and the electric telescopic rod 9 can then be moved to the top of the other passivation tank 2 to facilitate the removal of the loading cylinder 4 in the other passivation tank 2 or the placement of the other loading cylinder 4 into the other passivation tank 2, thereby improving the passivation efficiency of the metal parts.

[0021] like Figure 1As shown, a tilted blanking frame 23 with one side open is fixed to one side of the passivation tank 2, and a reinforcing plate 24 is fixed between the blanking frame 23 and the bottom plate 1; a support rod 22 connected to the inner wall of the passivation tank 2 is fixed to the bottom of the fixing frame 21. When the passivation of the metal parts in the passivation tank 2 is completed, the electric telescopic rod 9 can be coordinated with the hanging plate 91 to lift the mounting plate 7 upward, and the movable plate 3 drives the loading cylinder 4 to move above the passivation tank 2, and then the No. 2 motor 85 is started to rotate the screw rod 84, so that the slider 83 drives the electric telescopic rod 9 to move to the top of the blanking frame 23; when the loading cylinder 4 is directly above the blanking frame 23, the No. 1 motor 34 is started to rotate the loading cylinder 4 so that the opening 41 is located below the loading cylinder 4. At this time, the connecting cylinder 5 is not squeezed, and the connecting cylinder 5 is located below the opening 41. The metal parts in the loading cylinder 4 can fall down through the opening 41 into the blanking frame 23, and then be discharged through the blanking frame 23; the reinforcement plate 24 can increase the firmness of the connection between the blanking frame 23 and the passivation tank 2, and the support rod 22 can fix the fixed frame 21 in the passivation tank 2.

[0022] like Figure 2 、 Figure 3 and Figure 5 As shown, a limiting rod 52 is fixed to the bottom of the fixed plate 54 and passes through the inside of the spring 53. A recessed hole that matches the limiting rod 52 is formed at the top of the L-shaped rod 51. Two symmetrical partitions 42 are fixed to the loading cylinder 4, with an opening 41 located between the two partitions 42, and both partitions 42 are located between the two L-shaped rods 51. A reinforcement rod 33 is fixed between the two movable plates 3 and located above the loading cylinder 4. The limiting rod 52 limits the spring 53, ensuring that it can only be compressed vertically. The partition 42 separates the spring 53 and the L-shaped rod 51 to prevent contact between metal parts, the spring 53 or the L-shaped rod 51, and a leakage hole is formed in the partition 42. The reinforcement rod 33 strengthens the connection between the two movable plates 3.

[0023] When in use, the opening 41 is located at the top of the loading cylinder 4. At this time, the connecting cylinder 5 is not squeezed, the spring 53 is in a relaxed state, and the connecting cylinder 5 is located above the opening 41. The staff can put the metal parts into the loading cylinder 4 through the opening 41; then start the electric telescopic rod 9 to make the movable plate 3 enter the passivation tank 2, and the loading cylinder 4 enters the inner side of the fixed frame 21 (the inner diameter of the fixed frame 21 decreases from top to bottom, such as Figure 2), the metal parts are immersed in the passivation liquid, and then the No. 1 motor 34 is started to drive the loading cylinder 4 to rotate. When the connecting cylinder 5 enters the inner side of the fixed frame 21 as the loading cylinder 4 moves, the connecting cylinder 5 contacts the inner wall of the fixed frame 21. Subsequently, as the loading cylinder 4 continues to rotate, the connecting cylinder 5 can compress the spring 53 through the L-shaped rod 51, so that the connecting cylinder 5 enters the opening 41 and seals the opening 41 to prevent the metal parts in the loading cylinder 4 from falling out through the opening 41; after the loading cylinder 4 rotates, the metal parts in the loading cylinder 4 can be repeatedly moved so that the metal parts can fully contact the passivation liquid. When the passivation of the metal parts is completed, the opening 41 is located at the top of the loading cylinder 4, and then the electric telescopic After the rod 9 moves the movable plate 3 upward and the loading cylinder 4 moves outside the passivation tank 2, the No. 1 motor 34 can be started to drive the loading cylinder 4 to rotate so that the opening 41 is located at the bottom of the loading cylinder 4. At this time, the connecting cylinder 5 is not squeezed, the spring 53 is in a relaxed state, and the connecting cylinder 5 is located below the opening 41. The metal parts in the loading cylinder 4 can fall out of the loading cylinder 4 through the opening 41; the No. 1 motor 34 can also adopt a servo motor, so that when the loading cylinder 4 is above the passivation tank 2, the loading cylinder 4 can be repeatedly driven to rotate clockwise and counterclockwise in a small amplitude (the rotation amplitude is controlled within 40°), so that the passivation liquid on the metal parts can be better dripped into the passivation tank 2, and the metal parts can be prevented from falling out.
