[0018] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.
[0019] like Figure 1-6As shown, a screw chrome plating device includes a chrome plating treatment pool 2, and at least one group of supporting components is provided in the chrome plating treatment pool 2, the supporting component includes a bottom plate 26, and vertical rods 3 are symmetrically provided on the upper surface of the bottom plate 26. A center tube 4 is provided on the bottom plate 26 and located in the middle of the two vertical rods 3. The vertical rods 3 and the center tube 4 are connected by a cross bar 5. A number of side plates 6 are evenly provided on the same side of the two vertical rods 3, and a fixed seat 7 is provided at one end of the side plate 6. A fixed shaft 8 is provided between the side plate 6 and the vertical rod 3, and a movable seat 9 is rotatably connected to the fixed shaft 8. One end of the movable seat 9 is rotatably connected to the support plate 10, and a vertical plate 11 is slidably connected to one side of the center tube 4, and also includes a horizontal shaft 12 rotatably connected to the vertical plate 11, and the two ends of the horizontal shaft 12 are rotatably connected to the support plates 10 on both sides of the center tube 4. A first cylinder 13 is provided inside the center tube 4, and a top plate 14 is provided at the upper end of the vertical plate 11. The output end of the first cylinder 13 is fixedly connected to the top plate 14.
[0020] Before the screw 1 is chrome-plated in the chrome-plating tank 2, the screw 1 is first placed on two fixed seats 7 at the same horizontal height. During the chrome-plating process, the first cylinder 13 is started, and the output end of the first cylinder 13 retracts. At the same time, the vertical plate 11 is driven downward by the top plate 14 fixedly connected thereto. When the vertical plate 11 moves downward, the horizontal axis 12 is driven downward. When the horizontal axis 12 moves downward, the movable seat 9 is driven to swing around the fixed axis 8 through the support plate 10. The end of the movable seat 9 close to the support plate 10 moves downward, and the end of the movable seat 9 away from the support plate 10 moves upward. At this time, the movable seat 9 can lift the screw 1 between the two fixed seats 7 upward. When the screw 1 is lifted up a certain distance, the output end of the first cylinder 13 extends, which will drive the end of the movable seat 9 close to the support plate 10 to move upward, and the other end of the movable seat 9 moves downward, thereby replacing the screw 1 on the movable seat 9 on the two fixed seats 7. By repeatedly controlling the swing of the movable seat 9, the screw 1 is constantly switched between the fixed seat 7 and the movable seat 9, thereby avoiding the movable seat 9 and the fixed seat 7 from maintaining long-term contact with the same position of the screw 1, which can improve the chrome plating effect of the screw 1.
[0021] When the screw 1 moves up and down, the screw 1 is always located in the treatment liquid in the chrome plating treatment tank 2, so that the screw 1 can be effectively chrome-plated.
[0022] Furthermore, the upper surfaces of the fixed seat 7 and the movable seat 9 are both concave arcs, which can provide placement stability for the screw 1. The upper surfaces of the fixed seat 7 and the movable seat 9 are both provided with protrusions 15 for reducing the contact area with the screw 1.
[0023] Furthermore, a mounting frame 16 is provided on the chrome plating treatment pool 2, a fixing plate 17 is provided on the mounting frame 16, two guide rods 18 are symmetrically provided on the fixing plate 17, a through groove is symmetrically opened on the fixing plate 17, and a base 19 is located in the through groove and slidably connected to the two guide rods 18, a lead screw 20 threadedly connected to the base 19 is provided on the fixing plate 17, a motor 21 for driving the lead screw 20 to rotate is provided on the fixing plate 17, a second cylinder 22 is symmetrically provided on the lower surface of the base 19, and a picking rack 23 is provided at the output end of the second cylinder 22, and a storage rack 24 is provided at one end of the chrome plating treatment pool 2, the storage rack 24 is used to place the screw 1, and the picking rack 23 is used to remove the screw 1 on the storage rack 24 and transfer the removed screw 1 to the fixed seat 7 in the support assembly.
[0024] The storage rack 24 and the retrieval rack 23 both have two vertical plates and an extension plate arranged on one side of the vertical plate. The extension plate is arranged obliquely upward so that the screw 1 can slide down to the bifurcation position of the extension plate and the vertical plate under the action of gravity. When the screw 1 on the storage rack 24 is moved to the fixed seat 7 through the retrieval rack 23, the output end of the second cylinder 22 is first controlled to extend to push the retrieval rack 23 to move downward. When the upper end of the uppermost extension plate on the retrieval rack 23 is lower than the lower end of the uppermost extension plate on the storage rack 24, the second cylinder 22 stops extending, and then the motor 21 is started. The motor 21 drives the lead screw 20 to rotate and drives the base 19 to move along the guide rod 18. When the base 19 moves, it drives the second cylinder 22 and the retrieval rack 23 to move toward the storage rack 24. When the extension plate on the retrieval rack 23 moves to just below the screw 1 on the storage rack 24, the motor 21 stops rotating. After the screw 1 is completely removed from the rack 24, the height of the rack 23 is raised by the second cylinder 22, and the rotation of the motor 21 is controlled to move the rack 23 above the chrome plating tank 2, and then the second cylinder 22 is controlled to make the rack 23 enter the chrome plating tank 2, and then the motor 21 cooperates with the second cylinder 22 to transfer the screw 1 on the rack 23 to the fixed seat 7 in the manner of taking out the screw 1 from the rack 24, so that the screw 1 on the rack 24 can be transferred to the fixed seat 7 in the chrome plating tank 2.
[0025] In both cases where the take-out rack 23 is not loaded with the screw rod 1 and is loaded with the screw rod 1 , the take-out rack 23 is perpendicular to the ground.
[0026] Furthermore, two groups of second cylinders 22 are provided to improve the stability of the taking rack 23 when moving.
[0027] Furthermore, a reinforcement tube 25 for reinforcing the second cylinder 22 is provided on the lower surface of the base 19 .
[0028] When the device is in use, the fixed seat 7 and the movable seat 9 can alternately support the screw 1, thereby preventing a certain part of the screw 1 from being covered for a long time, thereby improving the chrome plating quality of the screw 1 and achieving good use effect.
[0029] In the description of this utility model, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.
