[0002] Electroplating racks come in different types depending on the shape of the part, the technical requirements of the plating layer, the electroplating process, and the equipment used. For example, there are differences between automated lines and manual lines. Electroplating workshops typically prepare general-purpose racks suitable for various common parts, as well as specialized racks designed and manufactured specifically for certain parts. General-purpose racks come in many forms and are suitable for a variety of processes and parts.
[0003] In current technology, during the electroplating process, the electroplating solution needs to cover the outer surface of the part and there cannot be any obvious defects. When there are deep blind holes after the part is machined, the electroplating solution is difficult to flow, and there is no potential difference between the hole opening and the bottom of the hole. Under normal circumstances, the fixture cannot extend into the blind hole, making it difficult to plate inside the hole, especially at the bottom, which affects the electroplating quality of the part.
[0004] Therefore, an electroplating rack is proposed to address the above problems. Utility Model Content

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] Specific implementation examples are given below.
[0026] Please see Figure 1 - Figure 5 This utility model provides an electroplating hanger, including a hanger body 1, an electroplating part 2 passing through the interior of the hanger body 1, a blind hole 21 at the center of one end of the electroplating part 2, clamping holes 22 symmetrically opened on both sides of the electroplating part, clamping screws 11 symmetrically installed on both sides of the hanger body 1, and multiple clamping screws 11 respectively threadedly engaging with multiple clamping holes 22, hanger extension rods 3 symmetrically arranged at both ends of the hanger body 1, one end of the hanger extension rod 3 being fixed to the center of both sides of the hanger body 1 by screws, and an electrode fixing plate 4 being fixed between one end of two hanger extension rods 3, the electrode fixing plate 4 being close to the hanger body 1. An electrode rod 5 is installed at the center of the side. One end of the electrode rod 5 extends into the blind hole 21 of the part. The electroplated part 2 is installed by the hanging body 1 through the clamping screw 11 and the screw connection between it and the clamping hole 22 on its side wall. This allows the electroplated part 2 to be immersed in the electroplating solution along with the hanging body 1. The electrode fixing plate 4, which is installed at one end of the hanging extension rod 3, extends into the blind hole 21 of the part through the electrode rod 5 fixed on its side wall. This allows the electroplating solution to cover the inner wall of the blind hole 21 of the part under the action of the electrode rod 5 after the electroplated part 2 is immersed in the electroplating solution along with the hanging body 1. This increases the relative surface contact of the outer electroplated surface of the electroplated part 2.
[0027] like Figure 4 and Figure 5 As shown, the hanger extension rod 3 is configured in two sections. One end of the hanger extension rod 3 near the electrode fixing plate 4 is fixedly connected to an extension inner core 31, and the other end of the hanger extension rod 3 is fixedly connected to an extension outer tube 32. The extension outer tube 32 and the extension inner core 31 are fitted together. The relative length of the hanger extension rod 3 can be changed within a certain range due to the fitted cooperation between the extension inner core 31 and the extension outer tube 32, thereby adapting to the size of the electroplated part 2 within a certain range. This ensures that the electrode rod 5 extends to a suitable position in the blind hole 21 of the part, and the electrode rod 5 installed on the side wall of the electrode fixing plate 4 can be replaced with the corresponding size according to the requirements of the blind hole 21 of the part, increasing the adaptability of the device to the size of the electroplated part 2.
[0028] like Figure 4 and Figure 5 As shown, multiple limiting through holes 33 are provided on the outer walls of both the extended outer tube 32 and the extended inner core 31. The multiple limiting through holes 33 are equally spaced along the extension direction of the hanger extension rod 3. An adjustment mechanism 6 is provided between the outer walls of the two extended outer tubes 32. The adjustment mechanism 6 includes a first arc-shaped rod 61. Both ends of the first arc-shaped rod 61 are fixedly connected to fixing sleeves 62. The two fixing sleeves 62 are respectively fixed to the outer walls of the two extended outer tubes 32. After the relative lengths of the extended inner core 31 and the extended outer tube 32 of the two hanger extension rods 3 are adjusted by mutual pulling, the relative lengths are limited by the adjustment mechanism 6 passing through the limiting through holes 33. The adjustment mechanism 6 is limited by the mutual fixation between the fixing sleeves 62 at both ends of the first arc-shaped rod 61 and the outer walls of the extended outer tubes 32.
[0029] like Figure 4 and Figure 5As shown, an L-shaped bracket 63 is fixedly connected to the outer wall of the fixing sleeve 62. One end of the L-shaped bracket 63 has a polygonal hole 64. A polygonal prism 65 is slidably fitted inside the polygonal hole 64. A core sleeve limiting plate 66 is fixedly connected to one end of the polygonal prism 65. The core sleeve limiting plate 66 is fitted with the inner wall of the limiting through hole 33 of the extended inner core 31 and the extended outer tube 32 through a protrusion. A spring 67 is fitted on the outer wall of the polygonal prism 65. The spring 67 is located between the adjacent side walls of the L-shaped bracket 63 and the core sleeve limiting plate 66. A second arc-shaped rod 68 is fixedly connected to the other end of the polygonal prism 65. The fixing sleeve 62, fixed to the outer wall of the extended outer tube 32, installs the polygonal prism 65 through the polygonal hole 64 on the L-shaped bracket 63. The column 65 limits the relative length of the hanger extension rod 3 by engaging with the protruding post on the core sleeve limiting plate 66 and the limiting through hole 33. When the relative length of the hanger extension rod 3 needs to be adjusted, the second arc rod 68 and the first arc rod 61 are pulled in opposite directions to overcome the elastic force of the spring 67. At this time, the protruding post on the core sleeve limiting plate 66 disengages from the limiting through hole 33 of the extension inner core 31 and the extension outer tube 32. Then the fitting degree between the extension inner core 31 and the extension outer tube 32 can be adjusted. After the adjustment is completed, the external pulling force is released, so that the core sleeve limiting plate 66 resumes the engagement with the limiting through hole 33 of the extension inner core 31 and the extension outer tube 32, thus limiting the relative length of the hanger extension rod 3.
[0030] Working principle: The electroplated part 2 is installed in the hanger body 1 by the screw connection between the clamping screw 11 and the clamping hole 22 on its side wall, allowing the electroplated part 2 to be immersed in the electroplating solution along with the hanger body 1. The electrode fixing plate 4 installed at one end of the hanger extension rod 3 extends into the blind hole 21 of the part through the electrode rod 5 fixed on its side wall. This allows the electroplating solution to cover the inner wall of the blind hole 21 of the part under the action of the electrode rod 5 after the electroplated part 2 is immersed in the electroplating solution along with the hanger body 1. The relative length of the hanger extension rod 3 can be changed within a certain range by the fitting between the mutually fitted extension inner core 31 and extension outer tube 32. After the relative length of the two hanger extension rods 3 is adjusted by mutual pulling, the relative length is limited by the adjustment mechanism 6 passing through the limiting through hole 33. The adjustment mechanism 6 is fixed by the first arc rod 61 at both ends of the fixed sleeve 62. The mutual fixation between the outer walls of the extended outer tube 32 is limited. The fixing sleeve 62 fixed to the outer wall of the extended outer tube 32 is installed on the polygonal prism 65 through the opening of the polygonal hole 64 on the L-shaped bracket 63. The polygonal prism 65 limits the relative length of the hanger extension rod 3 through the mutual engagement between the protrusion on the core sleeve limiting plate 66 and the limiting through hole 33. When it is necessary to adjust the relative length of the hanger extension rod 3, the opposite pulling force is applied to the second arc rod 68 and the first arc rod 61 to overcome the elastic force of the spring 67. At this time, the protrusion on the core sleeve limiting plate 66 disengages from the limiting through hole 33 of the extended inner core 31 and the extended outer tube 32. Then the fitting degree between the extended inner core 31 and the extended outer tube 32 can be adjusted. After the adjustment is completed, the external pulling force is released, so that the core sleeve limiting plate 66 resumes the engagement with the upper limiting through hole 33 of the extended inner core 31 and the extended outer tube 32, thus limiting the relative length of the hanger extension rod 3.
