Embodiment Construction

[0029] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings, but the claimed protection scope is not limited to the description.

[0030] In the present invention, the inner surface and the outer surface of the ball seat are electroplated separately, so two sets of devices are designed and manufactured, the inner surface chrome-plated component and the outer surface chrome-plated component.

[0031] The chrome-plated component on the inner surface of the part is composed of the first hook 1, the screw 3, the conductive plate 2, the positioning piece 4, the auxiliary anode electrode 8, the nut 7, and the bolt 6 (see figure 2 ).

[0032] The conductive plate 2 should be coaxially installed with the positioning part 4, and the center of the conductive plate 2 has The through hole is conducive to the circulation of the bath, but the diameter is smaller than the outer diameter of the part 5, which is used t...

Abstract

The invention discloses a ball cup inner-outer surface chroming device which comprises an inner surface chroming component and an outer surface chroming component. The inner surface chroming componentcomprises a first hook (1), a conductive plate (2), a positioning member (4) and an auxiliary anode electrode (8), and the outer surface chroming component comprises a first mandrel (11), a gasket (12), a washer (13), a second mandrel (14) and a connection block (15). The inner surface and the outer surface are chromed separately, so that inner-outer surface coating quality can be improved more easily, the problem of product quality stability is solved, production efficiency is improved, and the ball cup inner-outer surface chroming device plays an active role in scientific and research production.

Description

technical field [0001] The invention relates to a device for chrome-plating the inner surface and the outer surface of a ball head seat part, and belongs to the technical field of metal material surface treatment. Background technique [0002] Due to the poor dispersion ability of the chromium plating bath, the efficiency of the cathode and anode current is low, it is difficult to obtain a qualified coating for small hole parts, and there are problems such as difficult plating, uneven coating, frequent rework, and low processing efficiency. Generally, it is necessary to design special fixtures for chrome plating according to the structure of the parts, and optimize the process parameters to solve the difficulties in chrome plating of small hole parts. The ball seat described in this invention (the schematic diagram sees figure 1 ) requires hard chrome plating on the inner and outer surfaces, the inner diameter is only Φ24, the aperture is small, the processing is difficult,...
