Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Referring to Fig. 1, as can be seen, the utility model comprises shielding teabowl with a cover 1, chock 2 and packing ring 3 from the figure.From Fig. 5, Fig. 6 as can be seen, teabowl with a cover 1 is cylindric, and it has a chamber 4 that holds workpiece electroless plating position, and teabowl with a cover 1 upper end is uncovered, and the upper end is provided with internal thread, and at the bottom of the band of bottom, the bottom is provided with the through hole 5 that passes for workpiece.Chock 2 is used for end shield on the teabowl with a cover, and its underpart is provided with outside screw, and the outside screw by chock is connected both with the internal thread of teabowl with a cover.Chock 2 top shape of cross sections are by two symmetric semicircles and are positioned at the shape that the rectangle between two semicircles is formed, and are similar to the court runway, see Fig. 2, Fig. 3, are beneficial to tool operation like this, are convenient to upper and lower of workpiece.Packing ring 3 is a ring structure, sees Fig. 4, and the external diameter of packing ring 3 is greater than the diameter of through hole 5, and packing ring 3 just is unlikely to come off in through hole 5 like this.Simultaneously the electroplating region of workpiece and electroless plating district are isolated effectively in order to make packing ring 3 can block workpiece 6 tightly, packing ring 3 internal diameters are slightly less than workpiece 6 diameters, simultaneously on packing ring 3, opened a breach that is communicated with endoporus 9, so that workpiece can pass than self little hole of diameter.Packing ring 3 is positioned at teabowl with a cover 1 inner close fitting bottom, and the zone of transition that packing ring 3 is used to be enclosed within workpiece 6 electroless plating positions and electroplate the position is to isolate electroless plating position and electroplate liquid.Like this, by the acting in conjunction of chock 2, packing ring 3 and workpiece 6 self, the chamber 4 that teabowl with a cover holds workpiece electroless plating position is sealed.
During use, earlier packing ring 3 is stuck on the zone of transition at workpiece 6 electroless plating positions and plating position, the chock 2 of outwarding winding allows workpiece electroplate the position and passes by the through hole 5 of teabowl with a cover chamber 4 from the bottom, and packing ring 3 is attached to the teabowl with a cover bottom.At this moment, workpiece is electroplated the position and is positioned at outside the chamber, and workpiece electroless plating position is positioned at chamber.Then, with chock 2 with end shield on the teabowl with a cover 1, when chock 2 lower surfaces withstand on workpiece 6 upper surfaces, shielding puts in place, and workpiece 6 is also located, and unlikely waving inserted workpiece 6 extending parts (promptly electroplating the position) in the support 7 that is welded on the trunk 8 at last and (seen Fig. 1, reflected installation, the arrangement mode of one group of four such shielding unit when reality is electroplated on the figure), can put into coating bath after installing and begin to electroplate.
