[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] Please see Figure 1 - Figure 4 A pickling and phosphating device for oil tank production in this embodiment includes a rectangular base plate 1, a support frame 2 fixedly connected to the top of the rectangular base plate 1, a sliding groove 3 opened on the top of the support frame 2, a sliding plate 4 slidably connected to the inner wall of the sliding groove 3, a threaded rod 5 passing through the side of the support frame 2, the threaded rod 5 passing through the sliding plate 4 and threadedly connected to the sliding plate 4, and a motor 6 provided on the side of the support frame 2, one end of the threaded rod 5 being fixedly connected to the output end of the motor 6;

[0026] The support frame 2 is equipped with a moving mechanism via a sliding plate 4. The moving mechanism includes a motor 14 for driving, a rotating shaft 11, a gear 12, a square cylinder 10, and a toothed plate 13.

[0027] A fixing component is provided at the bottom of the toothed plate 13;

[0028] When the oil tank is surface treated, motor 14 is started first. Under the action of the moving mechanism, the moving plate 15 will drive the oil tank on the two sliders 17 to move down until it extends into the acidic liquid placement chamber 8 in the placement box 7. After pickling is completed, the moving mechanism is started to retract the oil tank. Motor 6 is started and the threaded rod 5 will rotate. Under the limiting action of the sliding plate 4 by the sliding groove 3, the sliding plate 4 will drive the square cylinder 10 to move. When it moves to the top of the phosphating liquid placement chamber 9, the moving mechanism is started again to put the oil tank into the phosphating liquid placement chamber 9 for phosphating.

[0029] At this point, the automatic pickling and phosphating of the oil tank is completed, reducing manual intervention. Workers do not need to come into direct contact with acidic liquids, reducing the harm caused by acidic liquids to workers. At the same time, there is no need for excessive protective measures, reducing the burden on workers, improving work efficiency, and reducing work intensity.

[0030] A square cylinder 10 passes through the top of the sliding plate 4 and is fixedly connected to the sliding plate 4. A placement box 7 is provided on the top of the rectangular base plate 1. An acidic liquid placement chamber 8 is provided inside the placement box 7. A phosphating liquid placement chamber 9 is provided inside the placement box 7.

[0031] The rotating shaft 11 passes through one side of the square cylinder 10 and is rotatably connected to the square cylinder 10. One side of the gear 12 is fixedly connected to one end of the rotating shaft 11 that passes through the square cylinder 10. The toothed plate 13 is slidably connected to the inner wall of the square cylinder 10.

[0032] The toothed plate 13 meshes with the gear 12, and the other end of the rotating shaft 11 is fixedly connected to the output end of the motor 14.

[0033] When the oil tank is placed into the acidic liquid placement chamber 8 or the phosphating liquid placement chamber 9, the second motor 14 is started first. The second motor 14 will drive the rotating shaft 11 to rotate, and the rotating shaft 11 will drive the gear 12 to rotate. Because the gear 12 and the toothed plate 13 are meshed, the toothed plate 13 will move inside the square cylinder 10 when the gear 12 rotates, until it drives the moving plate 15 to place the oil tank into the acidic liquid placement chamber 8 or the phosphating liquid placement chamber 9.

[0034] At this point, the automatic placement of the oil tank into the acidic liquid placement chamber 8 or the phosphating liquid placement chamber 9 is completed, reducing manual intervention, decreasing the workload of staff, and improving work efficiency.

[0035] The fixing component includes a movable plate 15 fixedly connected to the bottom of the toothed plate 13. The top of the movable plate 15 is provided with a second slide groove 16. At least two sliders 17 are slidably connected to the inner wall of the second slide groove 16. The two sliders 17 are symmetrically distributed.

[0036] The top of the slider 17 is hinged to a connecting rod 18, the top of the connecting rod 18 is hinged to a connecting rod 19, and a connecting plate 20 is provided above the movable plate 15.

[0037] The two ends of the connecting plate 20 are respectively hinged to the top of the two connecting rods 19. The side of the toothed plate 13 is fixedly connected to the baffle 21, the bottom of the baffle 21 is fixedly connected to the electric telescopic rod 22, and the top of the connecting plate 20 is fixedly connected to the output end of the electric telescopic rod 22.

[0038] When the oil tank is fixed, the electric telescopic rod 22 is activated to retract upwards. At this time, the electric telescopic rod 22 will drive the connecting plate 20 to move upwards. The angle between the connecting plate 20 and the connecting rod 19 will change and become smaller. The angle between the connecting rod 19 and the slider 17 will also change and become smaller. Under the limiting effect of the sliding groove 16 on the slider 17, the two sliders 17 will move closer to each other, driving the fixing device on the slider 17 to fix the oil tank. At this time, the oil tank can be placed into the acid liquid placement chamber 8 in conjunction with the moving mechanism.

[0039] At this point, the oil tank is secured, preventing it from shaking or falling off during movement, thus making the device more stable. This also prevents the oil tank from falling into the acidic liquid storage chamber 8 or the phosphating liquid storage chamber 9 during downward movement, thus avoiding the possibility of splashing acidic liquid that could injure workers.

[0040] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
