Description

Technical Field

[0001] The utility model relates to the technical field of electrophoretic coating hangers, in particular to a fast-assembly hanger for electrophoretic coating. Background Art

[0002] Electrophoretic coating is a coating method that uses an external electric field to make particles such as pigments and resins suspended in the electrophoretic liquid migrate in a directional manner and deposit on the surface of a substrate of one of the electrodes. It has the characteristics of being water-soluble, non-toxic, and easy to automatically control. It has been rapidly widely used in the automotive, building materials, hardware, home appliance and other industries. During the electrophoretic coating process, it is often necessary to hang the workpiece to be coated on a hanger, and then lift the hanger through a lifting device and put it into the electrophoretic tank for processing.

[0003] The electrophoresis hanger is mainly fixed to the base by bolts and nuts, or even directly welded to the base, which makes the disassembly of the entire electrophoresis hanger cumbersome and complicated, and is not convenient for paint removal and cleaning of the hook. Utility Model Content

[0004] In view of the shortcomings of existing hangers, the utility model provides a quickly assembled hanger for electrophoretic coating, which has the advantages of being able to quickly assemble the workpiece hanger and ensuring that the hanger can be quickly detached from the hook, thus solving technical problems such as complicated hanger assembly and hanger detachment.

[0005] The utility model provides the following technical solution: a quick-assembly hanger for electrophoretic coating, comprising a base, and also comprising:

[0006] The hanger hook is fixedly installed on the middle part of the top surface of the base, a baffle bar is movably hinged on the hanger hook, and a workpiece hook is movably connected to the side of the base at equal intervals.

[0007] Preferably, the interior of the base includes:

[0008] A movable groove is provided inside the base and corresponds to the workpiece hook;

[0009] A tension spring, fixedly connected to the middle of the top surface of the inner cavity of the movable groove;

[0010] The slide plate is fixedly connected to the bottom surface of the tension spring.

[0011] Preferably, the skateboard includes:

[0012] A clamping block, wherein the number of the clamping blocks is two, and the two clamping blocks are symmetrically fixed on the bottom surface of the slide plate with the workpiece hook as the symmetry axis, and the clamping blocks are made of magnetic material;

[0013] A clamping groove is provided on the outer surface of the workpiece hook and is located at the movable groove;

[0014] When the clamping block is at the lowest stroke, the clamping block is clamped in the clamping slot.

[0015] Preferably, the interior of the base further includes:

[0016] An upper cavity is opened inside the upper side of the base;

[0017] A lower cavity is opened inside the base and is located at the lower side of the upper cavity;

[0018] A through hole is opened inside the base and is located between the upper cavity and the lower cavity, and the through hole connects the upper cavity with the lower cavity.

[0019] Preferably, the interior of the lower cavity includes:

[0020] A piston plate is slidably connected to the interior of the lower cavity, and the interior of the lower cavity is located on the upper side of the piston plate and is filled with a magnetic fluid;

[0021] A spring is fixedly connected to the middle of the top surface of the piston plate, and the top end of the spring is fixedly connected to the top surface of the lower cavity.

[0022] Preferably, the piston plate further comprises:

[0023] A push rod is fixedly connected to the middle part of the bottom surface of the piston plate, the lower part of the push rod passes through the bottom surface of the base, and a groove for the push rod to slide is provided inside the base.

[0024] Preferably, the interior of the hanger hook includes:

[0025] A slide groove is provided inside the hook of the hanger;

[0026] A magnetic slider, slidably connected to the interior of the slide groove;

[0027] A connecting rope is fixedly connected to the middle of the top surface of the magnetic slider, and one end of the connecting rope away from the magnetic slider extends out of the hanger hook and is fixedly connected to the blocking bar.

[0028] Compared with the prior art, the utility model has the following beneficial effects:

[0029] 1. By designing movable grooves, tension springs, slide plates, clamping blocks, upper cavities, lower cavities and clamping grooves, when the workpiece has been electrophoretically processed and the hanger needs to be cleaned, the operator only needs to press the push rod and apply an upward thrust to the push rod, so that the push rod drives the piston plate to move up, and the piston plate pushes the magnetic fluid in the lower cavity into the upper cavity. At this time, the magnetic attraction of the magnetic fluid on the clamping block is withdrawn, so that the slide plate moves upward under the potential energy of the tension spring and drives the clamping block to move upward, so that the clamping block leaves the clamping groove on the workpiece hook. At this time, the workpiece hook only needs to be pulled out from the base to complete the disassembly, which greatly shortens the disassembly time of the hanger and also improves the convenience of disassembly of the hanger.

[0030] 2. By designing the slide groove, magnetic slider and connecting rope, after the electrophoresis processing of the workpiece is completed, the push rod can be pushed upward to allow the magnetic fluid in the lower cavity to flow into the upper cavity. Since the magnetic slider will adsorb the magnetic fluid, the magnetic fluid in the upper cavity will exert a reverse adsorption force on the magnetic slider, causing the magnetic slider to move downward inside the slide groove, and the downward movement of the magnetic slider will exert a downward pulling force on the connecting rope, causing the connecting rope to pull the baffle to deflect, thereby opening the gap at the bottom of the hanger hook, making it easier to take the hanger from the hook, greatly improving work efficiency.

A baffle 3 is movably hinged on the hanger hook 2 to ensure the stability of the hanger hook 2 on the hook. Workpiece hooks 4 are equidistantly movably connected to the side of the base 1 for placing workpieces to be processed.

[0039] See also Figure 1-Figure 5 A movable groove 11 is provided inside the base 1 at a position corresponding to the workpiece hook 4 , and a tension spring 12 is fixedly welded to the middle of the top surface of the inner cavity of the movable groove 11 .

[0041] See also Figure 1-Figure 5 Two clamping blocks 14 are fixedly welded on the bottom surface of the slide plate 13. The two clamping blocks 14 are symmetrically distributed with the workpiece hook 4 as the symmetry axis, and the clamping blocks 14 are made of magnetic material.

[0042] A clamping groove 41 is formed on the outer surface of the workpiece hook 4 at the movable groove 11 .

[0043] When the clamping block 14 is at the lowest stroke, the clamping block 14 is clamped in the clamping slot 41 , and the workpiece hook 4 is fixed by the cooperation between the clamping block 14 and the clamping slot 41 , thereby reducing the complexity of fixing the workpiece hook 4 .

[0044] See also Figure 1-Figure 5 An upper cavity 15 is formed inside the upper side of the base 1 .

[0045] A lower cavity 16 is formed inside the base 1 below the upper cavity 15 .

[0046] A through hole 17 is provided inside the base 1 between the upper cavity 15 and the lower cavity 16 , and the through hole 17 connects the upper cavity 15 with the lower cavity 16 .

[0047] See also Figure 1-Figure 5The interior of the lower cavity 16 is slidably connected to a piston plate 18, and a magnetic fluid is installed inside the lower cavity 16 on the upper side of the piston plate 18 to ensure that the magnetic fluid in the lower cavity 16 can enter the upper cavity 15 through the through hole 17 when the piston plate 18 moves upward, thereby causing the magnetic fluid to leave the magnetic field range of the block 14.

[0048] A spring 181 is fixedly welded to the middle of the top surface of the piston plate 18 , and the top end of the spring 181 is fixedly welded to the top surface of the lower cavity 16 , so that the piston plate 18 is reset by the elastic potential energy of the spring 181 .

[0049] See also Figure 1-Figure 5 A push rod 19 is fixedly welded to the middle of the bottom surface of the piston plate 18, the lower part of the push rod 19 passes through the bottom surface of the base 1, and a groove for the push rod 19 to slide is opened inside the base 1, and the movement of the push rod 19 drives the piston plate 18 to move.

[0050] See also Figure 1-Figure 5 A slide groove 21 is provided inside the hanger hook 2, and a magnetic slider 22 is slidably connected inside the slide groove 21.

[0051] A connecting rope 23 is fixedly connected to the middle of the top surface of the magnetic slider 22. One end of the connecting rope 23 away from the magnetic slider 22 extends out of the hanger hook 2 and is fixedly connected to the baffle bar 3, ensuring that when the magnetic slider 22 moves downward, the connecting rope 23 applies a downward pulling force to the baffle bar 3, causing the baffle bar 3 to deflect, thereby opening the bottom gap of the hanger hook 2.

[0052] Working principle: when the workpiece needs to be electrophoretically coated, the workpiece is hung on the workpiece hook 4, and then the hanger is hung on the hook through the hanger hook 2. At this time, since the magnetic fluid is in the lower cavity 16, the magnetic fluid is just in the magnetic field range of the clamping block 14. Since the clamping block 14 will adsorb the magnetic fluid, the magnetic fluid will apply a reverse adsorption force to the clamping block 14, thereby ensuring that the clamping block 14 is always clamped in the clamping groove 41 on the workpiece hook 4, greatly improving the stability of the workpiece hook 4. When the electrophoretic coating is completed and the hanger needs to be cleaned, the operator only needs to press the push rod 19 and apply an upward thrust to the push rod 19, so that the push rod 19 will drive the piston plate 18 to move upward. When the piston plate 18 moves upward, it will squeeze the magnetic fluid in the lower cavity 16, so that the magnetic fluid enters the upper cavity 15 through the through hole 17, and the magnetic fluid in the upper cavity 15 is no longer in the clamping groove 41. The magnetic field of block 14 is within the range of the magnetic field of block 14, so that the reverse adsorption force of the magnetic fluid on the card block 14 is withdrawn. At this time, the potential energy of the tension spring 12 pulls the slide plate 13 up, and the slide plate 13 drives the card block 14 to move up, so that the card block 14 leaves the card slot 41 on the workpiece hook 4. Then the operator only needs to pull out the workpiece hook 4 to complete the disassembly of the hanger, which greatly improves the convenience of disassembly of the hanger. Secondly, when the hanger needs to be taken from the hook, it is only necessary to apply an upward thrust to the push rod 19 to make the magnetic fluid enter the upper cavity 15. The magnetic fluid in the upper cavity 15 will adsorb the magnetic slider 22, so that the magnetic slider 22 slides down in the slide groove 21. The sliding magnetic slider 22 applies a downward pulling force to the connecting rope 23, so that the connecting rope 23 pulls the baffle bar 3 to deflect downward, causing the gap at the bottom of the hanger hook 2 to open, thereby facilitating the hanger hook 2 to be taken from the hook, thereby improving work efficiency.
