Description

Technical Field

[0001] This utility model belongs to the field of electrophoresis-related technology, specifically relating to a partial electrophoresis masking fixture for automotive shock absorbers. Background Technology

[0002] To mitigate and dampen the impacts and vibrations caused by uneven road surfaces during driving, ensuring a smooth and comfortable ride, and contributing to the vehicle's lifespan and handling stability, shock absorbers are installed on all vehicles. To give the shock absorbers an excellent appearance and protective layer, a uniform and dense film is formed on their outer surface using an electrophoresis process.

[0003] It is known that during electrophoresis, automotive shock absorbers need to be suspended by a hanger and placed into the electrophoresis tank for treatment. However, automotive shock absorbers consist of a cylindrical body and accessories with an opening on one side, and their outer surface lacks suitable clamping points and hanging points. How to clamp and suspend them onto the hanger is a problem we need to consider. Furthermore, automotive shock absorbers are only coated on the outer surface, with the inner surface uncoated, but during electrophoresis, they need to be completely immersed in the tank. How to ensure that the inner surface is free of coating is also a problem we need to consider. Based on these reasons, we have developed a partial electrophoresis masking fixture for automotive shock absorbers. Summary of the Invention

[0004] This utility model provides a partial electrophoresis shielding fixture for automotive shock absorbers, which can both detach and fix the automotive shock absorber for easy hanging on the hanger, and seal one side opening of the automotive shock absorber cylinder to ensure that the electrophoresis solution does not enter the inner wall of the cylinder and adhere to form a coating during the electrophoresis process.

DETAILED DESCRIPTION

[0016] In order to make the purpose, technical scheme and advantages of the utility model more clear and intelligible, the utility model will be further described below in combination with specific implementation manners. Among them, the figure is only used for example description, and the representation is only a schematic view, not a real object figure, and cannot be understood as a limitation on the patent; for those skilled in the art, it is understandable that some known structures and their descriptions in the figure can be omitted.

[0017] The utility model discloses a local electrophoresis shielding tool of automobile shock absorber, including the pole body 1 with external thread, the pole body is the metal material of good conductivity, one end of pole body 1 is provided with support 2, and the support 2 is also the metal material of good conductivity, the support 2 has two open struts 21, and the two struts can approach each other when being stressed, the pole body 1 is provided with shielding piece 3 for plugging the opening of automobile shock absorber cylinder one side, and the other end of pole body 1 is provided with clamping cylinder 4. Among them, the shielding piece is polyurethane cylinder or polyurethane conical column, and the pole body is interference fit, and it is basically not moved after loading, and it is adapted with the cylinder inner diameter of automobile shock absorber, and it can be rotated from the opening side to realize good plugging, so that the electrophoresis solution does not enter the inner wall of cylinder and adhere to form a coating. Preferably, it is a polyurethane conical column, and the maximum diameter of the polyurethane conical column should be slightly larger than the inner diameter of the cylinder of the automobile shock absorber.

[0018] When in use, the two struts of the support are contracted, the pole body at one end of the support enters the shock absorber cylinder and moves inward, when moving to the shielding piece, the clamping cylinder is held by hand, the pole body is rotated, the shielding piece is slowly rotated into the shock absorber cylinder, and the fixing of the shock absorber and the shielding of the opening of the tool can be realized. Then, the automobile shock absorber provided with the tool is moved to the hanger, the clamping cylinder of the tool is clamped by the clamp on the hanger, and the conductive part on the hanger is introduced into the clamping cylinder and contacted with the pole body. Since the other end of the pole body is contacted with the inside of the shock absorber cylinder through the two struts of the support, the shock absorber can be cathode after being put into the electrophoresis solution, and then the electrophoretic paint is adhered to the outer surface of the shock absorber.

[0019] Although the shielding piece is interference fit with the pole body, the shielding piece also bears a certain force when being rotated in and out. In order to avoid the movement of the shielding piece, the first gasket 5 and the first nut 6 are sleeved on the pole body 1 at the rear side of the shielding piece, the first nut 6 is threadedly connected on the pole body 1 and abuts against the shielding piece 3 through the first gasket 5, the second gasket 7 is sleeved on the pole body 1 at the front side of the shielding piece 3, and the clamping cylinder 4 is threadedly connected on the pole body 1 and abuts against the shielding piece 3 through the second gasket 7. The first nut and the clamping cylinder are used for limiting the shielding piece to ensure that it will not be loose. The first gasket and the second gasket are used for enhancing the connection firmness to prevent the pole body from stretching and contracting, in addition, the first gasket also plays a role of sealing the connection between the shielding piece and the pole body, and further prevents the electrophoresis solution from entering from the gap.

[0020] In the embodiment, the clamping cylinder 4 comprises a hollow sleeve 41 and a second nut 42 welded at one end of the hollow sleeve 41, the inner diameter of the second nut 42 is smaller than the inner diameter of the hollow sleeve 41, and the clamping cylinder 4 is threadedly connected with the rod body 1 through the second nut 42. Since the inner diameter of the second nut is smaller than the inner diameter of the hollow sleeve, the rod body located in the hollow sleeve does not contact the inner wall of the hollow sleeve, thereby reducing the current loss by reducing the contact between the rod body and the hollow sleeve; after the shock absorber is placed in the electrophoretic solution, most of the current is transmitted along the rod body to the cylinder body of the automobile shock absorber, and then to the entire shock absorber, so that the shock absorber becomes a cathode, and then the electrophoretic paint is attached to the outer surface of the shock absorber.

[0021] Further, the inner and outer surfaces of the hollow sleeve 41 and the second nut 42 are sprayed with an insulating layer, so that the clamping cylinder is insulated and non-conductive. This design can further ensure the correct distribution of current and help improve the utilization efficiency of current and prevent unnecessary current loss.

[0022] Further, the outer diameter of the second nut 42 is smaller than the outer diameter of the hollow sleeve 41, so that the connection between the second nut 42 and the hollow sleeve 41 can serve as a clamping part, facilitating the use of a splayed clamp or a U-shaped clamp to clamp this part.

[0023] In the embodiment, the support 2 is a steel wire wound on the rod body, the two ends of the steel wire extend outward to form two struts 21; the steel wire has the required hardness and good electrical conductivity, and the two struts 21 have an arc-shaped bending part 22 at the end away from the rod body, the arc-shaped bending part enables the support rod body to move along the inner wall of the shock absorber cylinder without scratching the inner wall of the shock absorber cylinder.

[0024] The above design mainly uses a shielding member to realize fixation with the cylinder body of the automobile shock absorber and later suspension support, in order to share the stress and further ensure that the automobile shock absorber does not fall off during suspension, the rod body 1 near the support has a reinforcing member 8 sleeved thereon, the reinforcing member can be inserted into the cylinder body of the shock absorber and adapted thereto, the rod body on the front side of the reinforcing member 8 has a third gasket 9 and a third nut 10 sleeved thereon, the third nut 10 is threadedly connected with the rod body 1 and abuts against the reinforcing member 8 through the third gasket 9, and the rod body 1 on the rear side of the support has a fourth nut 11 sleeved thereon, the fourth nut 11 is threadedly connected with the rod body 1 and abuts against the reinforcing member 8 through the support.

[0025] The reinforcing member is a polyurethane conical column, and the maximum diameter thereof is equal to or slightly smaller than the inner diameter of the cylinder body of the automobile shock absorber, facilitating screwing. The reinforcing member is in interference fit with the rod body, and basically does not move after being installed, and at the same time, the third nut and the fourth nut jointly limit the reinforcing member, ensuring that the reinforcing member does not loosen. In addition, the support is clamped between the reinforcing member and the fourth nut, so that it does not move under the force of rotating the rod body.
