Description

Technical Field

[0001] This utility model relates to the field of phosphating tank technology, and in particular to a swing-type phosphating tank for low-temperature phosphating liquid processing. Background Technology

[0002] Phosphating is an important process for metal surface treatment, which significantly improves the corrosion resistance and coating adhesion of metal workpieces. Low-temperature phosphating solutions are widely used in modern industry due to their energy-saving and environmentally friendly characteristics. The phosphating tank is the core device for implementing phosphating treatment, and its technical performance directly affects the phosphating quality and efficiency. Traditional fixed phosphating tanks are prone to creating processing dead zones when processing workpieces with complex structures, resulting in uneven phosphating films. There is an urgent need to develop a new type of phosphating tank device that can improve the fluidity of the solution.

[0003] In existing technologies, phosphating is usually performed by static immersion or by suspending the workpiece on a fixed support. To improve the treatment effect, some improved solutions are implemented by adding a circulating pump to the outside of the tank to force the solution to flow, or by using a mechanical stirrer to agitate the phosphating solution. Most of these devices use a motor to drive the impeller to rotate and generate eddies, or use an air pump to generate bubbles to agitate the solution, which improves the fluidity of the phosphating solution to a certain extent.

[0004] However, traditional phosphating treatment usually uses a static immersion method, which makes it difficult to achieve uniform flow of the phosphating solution in all directions. This results in some parts of the workpiece still being in a relatively static liquid flow area, thus affecting the uniformity and efficiency of the phosphating treatment. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a swing-type phosphating tank for low-temperature phosphating solution processing, which aims to improve the problem that traditional phosphating treatment uses static immersion method, which makes it difficult to achieve all-round uniform flow of phosphating solution.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a swing-type phosphating tank for low-temperature phosphating liquid processing, comprising a square tank, wherein a support block is fixedly connected to the outer wall of the square tank, and a swing component is provided on the upper surface of the support block;

[0007] The swing assembly includes a motor, which is mounted on the upper surface of the support block. The output end of the motor is fixedly connected to a rotating shaft. A curved groove is formed inside the rotating shaft. A retaining shaft is slidably connected to the inner wall of the rotating shaft. A slider is fixedly connected to the upper surface of the retaining shaft. A swing shaft is slidably connected to the outer wall of the rotating shaft. A curved groove is formed inside the swing shaft. A retaining block is fixedly connected to one end of the swing shaft. A second insertion hole is formed through the retaining block.

[0008] Furthermore, a fixing block 1 is fixedly connected to the upper surface of the square groove, a screw 1 is threadedly connected to the inner wall of the fixing block 1, a fixing block 2 is threadedly connected to the outer wall of the screw 1, a straight groove is opened inside the fixing block 2, and a connecting component is provided on the lower surface of the fixing block 2.

[0009] Furthermore, the connecting assembly includes a driven shaft, a limit ring is fixedly connected to the outer wall of the driven shaft, a locking block is fixedly connected to one end of the driven shaft, an insert block is engaged with the outer wall of the locking block, an insertion hole is provided through the insert block, a support rod is fixedly connected to the outer wall of the insert block, a screw is provided on the inner wall of the insert block, and a nut is threaded to the outer wall of the screw.

[0010] Furthermore, the slider is slidably connected to the inner wall of the straight groove, and the outer wall of the retaining shaft is slidably connected to the inner wall of the curved groove.

[0011] Furthermore, the outer wall of the card shaft is slidably connected to the inner wall of the curved groove, and the swing shaft is rotatably connected to the upper surface of the fixed block.

[0012] Furthermore, the second screw passes through the first insertion hole and the second insertion hole in sequence, and is locked in place by the nut.

[0013] Furthermore, the support rod is positioned above the square groove, and the outer wall of the driven shaft is rotatably connected to the upper surface of the fixed block.

[0014] Furthermore, the limiting ring is disposed on one side of the outer wall of the second fixed block.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the swing assembly is driven by a motor to rotate the shaft. The clamping shaft can slide simultaneously in the first curved groove in the rotating shaft and the second curved groove in the swing shaft, and drive the slider to move within the straight groove of the fixed block. This converts the continuous rotation of the rotating shaft into the reciprocating swing of the swing shaft at a specific angle, effectively driving the support rod to swing and improving the uniformity and efficiency of the phosphating treatment.

[0017] 2. In this utility model, the connecting component utilizes the inserts at both ends of the support rod to quickly engage with the blocks on the swing shaft and the driven shaft, and is locked in place by screws and nuts, thereby enabling convenient installation and disassembly of the support rod, facilitating maintenance and replacement of workpieces. At the same time, it can reliably transmit the swing of the swing shaft to the support rod and the workpiece to be processed, causing it to swing in the phosphating solution, thus enhancing the phosphating effect.

[0025] 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.

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 An embodiment of this utility model is provided: a swing-type phosphating tank for low-temperature phosphating liquid processing, including a square tank 1. The square tank 1 is used to hold the phosphating liquid and accommodate the workpiece to be processed. It is the main container for phosphating treatment. A support block 2 is fixedly connected to the outer wall of the square tank 1. A swing component is provided on the upper surface of the support block 2.

[0027] The swing assembly includes a motor 3 and a support block 2 for providing a mounting support base for the motor 3. The motor 3 serves as a power source and outputs rotational motion. The motor 3 is mounted on the upper surface of the support block 2. A rotating shaft 13 is fixedly connected to the output end of the motor 3. The rotating shaft 13 is used to transmit the rotational motion of the motor 3 to the swing mechanism. A curved groove 11 is provided inside the rotating shaft 13. A retaining shaft 21 is slidably connected to the inner wall of the rotating shaft 13. The curved groove 11 is used to guide the retaining shaft 21 to slide along a specific trajectory inside the rotating shaft 13, converting the rotational motion into a specific swing. A slider 20 is fixedly connected to the upper surface of the retaining shaft 21. A swing shaft 12 is slidably connected to the outer wall of the rotating shaft 13. A curved groove 22 is provided inside the swing shaft 12. The retaining shaft 21 slides in both the curved groove 11 and the curved groove 22 to transmit the motion of the rotating shaft 13 to the swing shaft 12. A retaining block 9 is fixedly connected to one end of the swing shaft 12. A second insertion hole 10 is provided through the retaining block 9.

[0028] Specifically, the motor 3 is started, and the output end of the motor 3 is fixedly connected to the rotating shaft 13. When the rotating shaft 13 rotates, the retaining shaft 21 slides in the curved groove 11 opened inside the rotating shaft 13. The retaining shaft 21 also slides in the curved groove 22 opened inside the swing shaft 12. Since the slider 20 fixed above the retaining shaft 21 slides in the straight groove 14 opened inside the fixed block 25, the rotating shaft 13 drives the swing shaft 12 to swing when it rotates, thereby converting the continuous rotation of the rotating shaft 13 into the reciprocating swing of the swing shaft 12 at a specific angle.

[0029] Reference Figure 1 - Figure 6 A fixing block 4 is fixedly connected to the upper surface of the square groove 1. The fixing block 4 is fixed to the upper surface of the square groove 1 to provide rotational support for the swing shaft 12. A screw 7 is threadedly connected to the inner wall of the fixing block 4. A fixing block 5 is threadedly connected to the outer wall of the screw 7. The screw 7 is used to fix the fixing block 4 and the fixing block 5 together. A straight groove 14 is opened inside the fixing block 5. The straight groove 14 is used to limit the movement direction of the slider 20. The slider 20 slides in the straight groove 14 to limit the movement trajectory of the locking shaft 21. A connecting component is provided on the lower surface of the fixing block 5.

[0030] The connecting assembly includes a driven shaft 16, with a limiting ring 17 fixedly connected to the outer wall of the driven shaft 16. The limiting ring 17 is used to restrict the axial movement of the driven shaft 16. A locking block 9 is fixedly connected to one end of the driven shaft 16. An insert block 15 is engaged with the outer wall of the locking block 9. The locking block 9 is used to connect and fix the insert block 15. The insert block 15 is used to engage with the outer wall of the locking block 9. An insertion hole 8 is provided through the insert block 15. A support rod 6 is fixedly connected to the outer wall of the insert block 15. The driven shaft 16 is used to support the other end of the support rod 6 by moving synchronously with the swing shaft 12. The swing shaft 12 is used to receive the motion from the locking shaft 21 to generate a swing output to drive the support rod 6 to move. The support rod 6 is used to suspend and support the workpiece to be processed.

[0031] The inner wall of the insert block 15 is provided with a screw 18. The first insertion hole 8 and the second insertion hole 10 correspond to allow the screw 18 to pass through. The outer wall of the screw 18 is threaded with a nut 19. The screw 18 and the nut 19 cooperate to fix the connection between the insert block 15 and the locking block 9. The slider 20 is slidably connected to the inner wall of the straight groove 14. The outer wall of the locking shaft 21 is slidably connected to the inner wall of the first curved groove 11. The outer wall of the locking shaft 21 is slidably connected to the inner wall of the second curved groove 22. The swing shaft 12 is rotatably connected to the upper surface of the first fixed block 4. The screw 18 passes through the first insertion hole 8 and the second insertion hole 10 in sequence and is locked by the nut 19. The support rod 6 is set above the square groove 1. The outer wall of the driven shaft 16 is rotatably connected to the upper surface of the first fixed block 4. The limiting ring 17 is set on one side of the outer wall of the second fixed block 5.

[0032] Specifically, the inserts 15 at both ends of the support rod 6 are engaged with the outer wall of the insert 9 at one end of the driven shaft 16 and the swing shaft 12. The outer wall of the driven shaft 16 is fixedly connected with a limit ring 17. Then, screws 18 are passed through the first insertion hole 8 and the second insertion hole 10 and tightened with nuts 19 to fix the support rod 6. This achieves the effect of fixing the support rod 6, making it easy to install and remove the support rod 6, facilitating maintenance and replacement of the workpiece. At the same time, it can reliably transmit the swing of the swing shaft 12 to the support rod 6 and the workpiece to be processed.

[0033] Working principle: When the device is needed, first place the square groove 1 on a flat ground, and hang the workpiece to be processed on the support rod 6 above the square groove 1. Place the workpiece in the phosphating solution inside the square groove 1 for phosphating. When the swing component is needed, start the motor 3 above the support block 2. The output end of the motor 3 is fixedly connected to the rotating shaft 13. When the rotating shaft 13 rotates, the clamping shaft 21 slides in the curved groove 11 opened inside the rotating shaft 13. The clamping shaft 21 also slides in the curved groove 22 opened inside the swing shaft 12.

[0034] Since the slider 20 fixed above the locking shaft 21 slides inside the straight groove 14 opened inside the second fixing block 5, the rotating shaft 13 rotates and drives the swing shaft 12 to swing. The swing shaft 12 rotates between the first fixing block 4 and the second fixing block 5. The first fixing block 4 and the second fixing block 5 are fixed by screw 7. When the connecting component is needed, firstly, the inserts 15 at both ends of the support rod 6 are engaged with the outer wall of the locking block 9 at one end of the driven shaft 16 and the swing shaft 12. The outer wall of the driven shaft 16 is fixedly connected with the limit ring 17. Then, screw 18 is used to pass through the first insertion hole 8 and the second insertion hole 10 and tightened by nut 19 to achieve the effect of fixing the support rod 6, so that the swing shaft 12 swings and drives the support rod 6 to swing.
