Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tooling fixtures for electroplating surface treatment, specifically, it relates to a tooling fixture for batch partial electroplating of rocker arm-type parts. Background Technology
[0002] A rocker arm-like component is used in an aircraft locking system; the component's shape is as follows: Figure 1 As shown, the structure is complex. To ensure the normal opening of the handle inside the aircraft cabin, the right-angle transition area of this rocker arm-like part needs to be smooth during assembly, forming a limiting and locking mechanism with the steel ball. To prevent this rocker arm-like part from jamming and to allow for a proper fit, the plating dimensions of the limiting area parts must be precise, and the surface must be wear-resistant and corrosion-resistant. Therefore, the requirements for its surface treatment are more stringent.
[0003] The large demand for parts, coupled with the cumbersome insulation process for each individual piece and inconsistent surface finish, impacts production efficiency and part surface quality. Some parts even require rework due to dimensional deviations, and even multiple stripping processes leading to scrap increases production costs. Localized electroplating has always been a challenging issue in electroplating production. By varying the shape and size of the plating area on the part, localized electroplating of the rocker arm can be controlled to a certain extent, saving production costs, improving the surface electroplating quality, and significantly shortening the production cycle. Utility Model Content
[0004] In view of the above-mentioned prior art, the purpose of this utility model is to overcome the shortcomings of the prior art, adapt to the actual needs, and thus provide a tooling fixture for batch partial electroplating of rocker arm parts that can solve the technical difficulties of batch partial electroplating of rocker arm parts, ensure that the surface treatment of the parts meets the plating requirements, avoid multiple deplating and replating failures caused by unclear plating size and plating area boundaries after plating, reduce the risk of scrap, reduce production costs, and improve the batch partial electroplating production efficiency.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a tooling fixture for batch partial electroplating of rocker arm parts, including a conductive copper hook, a cover plate, a shielding sleeve, a wing nut, a flat-head bolt, and a hexagonal nut. The rocker arm parts are stacked sequentially inside the shielding sleeve, with the area to be plated of the rocker arm parts exposed at the left end of the shielding sleeve. The cover plate is located at the upper end of the shielding sleeve to seal the top. One end of the conductive copper hook is suspended from the conductive copper rod in the plating tank, and the other end passes through the hexagonal nut, the right end of the cover plate, the waist-shaped hole of the rocker arm part, the right end of the shielding sleeve, and the wing nut from top to bottom to limit the rocker arm parts. The flat-head bolt passes through the left end of the cover plate, the square groove of the rocker arm part, the left end of the shielding sleeve, and the wing nut from top to bottom to tightly fit the rocker arm parts together.
[0006] Furthermore, the shielding sleeve includes a shielding base plate and a shielding frame. The appearance, size, and material of the shielding base plate are consistent with the appearance, size, and material of the rocker arm parts. The shielding frame is a hollow cover with openings at the left end, top, and bottom. The shape and size of the shielding frame match the shape and size of the non-plating area after multiple rocker arm parts are stacked. The bottom opening of the shielding frame wraps around the top of the shielding base plate and forms a cavity with the same length as the shielding frame and openings at the left end and top. The rocker arm parts are stacked in sequence in the cavity, and the plating area of the rocker arm parts is exposed at the left end of the cavity.
[0007] Furthermore, the bottom of the shielding frame is welded to the upper part of the shielding base plate.
[0008] Furthermore, the cover plate's appearance, size, and material are consistent with the rocker arm parts' appearance, size, and material, and the cover plate is placed on the opening at the top of the shielding frame to seal it off.
[0009] Furthermore, one end of the conductive copper hook is hook-shaped, and the other end is a long rod. The long rod has threads that match the hexagonal nut and the wing nut. One end of the conductive copper hook is suspended from the conductive copper rod in the plating tank by the hook shape, and the other end passes through the hexagonal nut, the right end of the cover plate, the waist-shaped hole of the rocker arm part, the right end of the shielding sleeve, and the wing nut from top to bottom to limit the rocker arm part. By adjusting the hexagonal nut and the wing nut through the threads on the long rod of the conductive copper hook, the rocker arm part and the conductive copper hook are tightly combined together to achieve conductivity and shielding of non-electroplated areas.
[0010] Furthermore, the outer diameter of the long rod of the conductive copper hook is the same as the inner diameter of the waist-shaped hole of the rocker arm part.
[0011] Furthermore, the lower end of the flat-head bolt is provided with threads that match the wing nut.
[0012] In this invention, a conductive copper hook of the same diameter is manufactured based on the inner diameter of the center hole (i.e., the waist-shaped hole at the right end) of the rocker arm component. This conductive copper hook can directly contact the rocker arm component and provide conductivity. The upper end of the conductive copper hook is curved, resembling a hook, allowing the plated component to be directly suspended from the overall fixture onto the conductive copper rod in the plating tank, facilitating operation. The lower end of the conductive copper hook has a threaded section, which works in conjunction with a wing nut and a hexagonal nut to limit the component's position. The cover plate and the shielding base plate are made to match the appearance and material of the rocker arm component. The shielding frame is designed based on the non-plating area side of multiple stacked rocker arm components, wrapping around the shielding base plate and assembled together by welding. Multiple rocker arm components are stacked sequentially within the shielding sleeve, sealed with the cover plate, and the conductive copper hook is passed sequentially through the center hole of the hexagonal nut, the cover plate, the rocker arm component, the shielding base plate, and the wing nut. By utilizing the threads on the long rod area of the conductive copper hook, and adjusting the hexagonal nut and wing nut, the parts are tightly assembled with the conductive copper hook, serving to conduct electricity and shield non-electroplating areas. The flat-head bolts pass through the cover plate, the square groove of the rocker arm parts, and the shielding base plate. The lower end of the flat-head bolt 5 is threaded and can be used with the wing nut 4 to tighten and tightly fit the rocker arm parts together. This ensures the stability of the assembly of batch parts and the overall tooling fixture. After assembly, during the plating process, the anode must be directly facing the plating area, allowing for large-scale, precise, localized electroplating of parts in the same tank. This ensures part quality, avoids part scrap, and increases production efficiency.
[0013] The beneficial effects of this utility model are as follows: This utility model successfully solves the technical difficulties of batch partial electroplating of rocker arm parts, ensuring that the surface treatment of the parts meets the plating requirements. It avoids the failure of repeated deplating and replating due to problems such as unclear plating size and unclear plating area boundaries after plating, reduces the risk of scrap, reduces production costs, and improves the efficiency of batch electroplating production.
