Description
Technical Field
The utility model belongs to the technical field of electroplating, and particularly relates to an electroplating conductive and protective tool for an aircraft hydraulic pump rotor assembly.
Background
The surface of the N end face of the hydraulic pump rotor assembly needs to be plated with nickel 1-3 mu m and silver 3-6 mu m, and the flatness is ensured to be 5 mu m after the final surface treatment. In order to ensure that other products are matched with the inner hole, protection is required to be in place, plating layers are not allowed to be arranged on the inner hole and the inner surface of each groove, and meanwhile corrosion caused by various groove liquids entering the inside of the product is required to be avoided.
The N end face of the rotor assembly and the base materials below are welded by bronze and high-strength steel, and if the rotor assembly is not protected in place, acid liquor and alkali liquor enter the inside of a product, and corrosion can possibly lead to scrapping of the product. According to the traditional process, the inner hole is protected by a rubber plug with taper, and the copper wire is used for binding and conducting clamping, but the risk is high. Based on this, it is necessary to design an electroplating tool for effective protection.
Disclosure of Invention
In order to solve the problems in the prior art, the utility model provides an electroplating tool for an aircraft hydraulic pump rotor assembly; in the electroplating process, the depth of the electroplating solution penetrating into the bath solution is controlled within 20 mm; meanwhile, the tool can ensure stable performance of nickel plating, silver plating and other multiple processes, and the binding force is met after electroplating.
The technical scheme of the utility model is as follows:
the utility model provides an electroplating frock of aircraft hydraulic pump rotor subassembly, includes copper couple 1, threaded rod I2, copper rand 3, upper end cover 4, rubber circle 5, lower end cover 6 and threaded rod II 7.
The copper collar 3 is a ring structure formed by two semicircular rings, is fixed on the outer peripheral surface of the hydraulic pump rotor assembly in a fastening lock pin clamping mode, and plays a role in electric conduction.
Two threaded rods I2 are symmetrically arranged on the two semicircular rings of the copper collar 3, the top of each threaded rod I2 is connected with the copper hook 1 through threads, and the copper hook 1 is hung on a conducting rod during electroplating. The threaded rod I2 is matched with the copper hook 1 through threads, and is used for adjusting the hanging direction and the height so as to meet different liquid level heights of each plating tank, and finally, the product is ensured to be stably placed in a position of 20-30 mm below the liquid level.
The upper end cover 4 and the lower end cover 6 are round covers; the upper end cover 4 is arranged at the top end of the hydraulic pump rotor assembly, and the lower end cover 6 is arranged in an inner hole at the bottom end of the hydraulic pump rotor assembly; the threaded rod II 7 is matched with nuts at two ends of the threaded rod II, the upper end cover 4 and the lower end cover 6 are fixed and clamped at the upper end and the lower end of the hydraulic pump rotor assembly, and solution is prevented from entering from a bottom gap.
The rubber ring 5 is arranged between the lower end cover 6 and the hydraulic pump rotor assembly to play a role in sealing.
The utility model has the beneficial effects that: the utility model adopts the clamping and protection modes of up-down sealing and circumferential clamping, can ensure that the rotor assembly is clamped stably and firmly, has good conductive contact, can prevent an inner hole from entering a bath solution, ensures that plating and corrosion cannot occur at an electroless plating part, is beneficial to operators to enter the bath, go out of the bath, clean and check manually, and ensures that the liquid level of the entering bath is easy to control and the binding force of the silver plating.
