Technical field
The utility model relates to a kind of muzzle attachment when electroplating, the device that can shield its electroless plating position.
Background technology
At present, (mainly refer to chromium plating) when workpiece is electroplated, in order to prevent the electroless plating position coating is arranged, common way is to adopt insulation tape that liquid level is wrapped up and controlled at the electroless plating position just to finish.Local chromium plating to endoporus is more rare.
Muzzle attachment is a kind of mechanical part, and is to the muzzle attachment electroplating processes time, constant to guarantee fire accuracy, so need shield bore portion in the muzzle attachment for guaranteeing its endoporus ballistic-shaped.So how to design a kind of device that can shield muzzle attachment endoporus electroless plating position, becoming the present technique field has technical problem to be solved.
The utility model content
Technical problem to be solved in the utility model is, overcomes above-mentioned defective and provides the muzzle attachment that can shield muzzle attachment electroless plating position easily and effectively to electroplate shielding unit.
In order to solve the problems of the technologies described above, adopted following technical scheme in the utility model:
A kind of muzzle attachment is electroplated shielding unit, comprises parallel top end rail and the bottom end rail that is provided with, top end rail and bottom end rail two ends be connected on the support and on the upper and lower crossbeam an opposite end be provided with the support insulation separately; The bottom end rail upper surface is set side by side with several frustums, frustum shape and muzzle attachment hydraucone cavity shape coupling; Corresponding frustum is provided with several through holes on the top end rail, through hole is interior to the anode that is arranged with column, the anode of top end rail lower surface is arranged with the spring of crimping outward, collets of spring lower end crimping, the collets lower end has a boss that mates with muzzle attachment hydraucone the other end opening, the boss height equals the muzzle attachment muzzle attachment hydraucone the other end endoporus electroless plating position degree of depth, muzzle attachment can be crimped between collets and the frustum under spring action; Collets inside vertically is provided with for anode and inserts the vertical passageway of connection and the interconnection that electrolysis hydrogen overflows.
When the utility model uses, muzzle attachment is crimped between bottom end rail frustum and the top end rail collets, when electroplating, after muzzle attachment is immersed in electroplate liquid, frustum and collets can form shielding to muzzle attachment endoporus electroless plating position, avoid at this position generation coating.Reach shield effectiveness, have the advantage of convenient practicality.Simultaneously, the utility model so can electroplate a plurality of muzzle attachments simultaneously, has improved production efficiency owing to be provided with a plurality of frustums.
As optimization, the cross side of through hole is provided with trip bolt on the described top end rail, is used for carrying out fastening to the anode that inserts through hole; Described anode lower end and collets interconnection corresponding position are provided with the crosswise fixed hole, after anode inserts collets, can pass the crosswise fixed hole by iron wire and make between anode and the collets fixing.The location is more convenient like this, and after each position all tightens up, can make one-piece construction compact, firm more in moving process.
In sum, the utility model can shield muzzle attachment electroless plating position when electroplating, and also possesses easy to operately, quick simultaneously, once can handle a plurality of muzzle attachments, the advantage of increasing work efficiency simultaneously.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
During concrete enforcement, as shown in Figure 1 to Figure 3, a kind of muzzle attachment is electroplated shielding unit, comprise parallel top end rail 1 and the bottom end rail 2 that is provided with, top end rail 1 and bottom end rail 2 two ends be connected on the support 3 and upper and lower crossbeam 1,2 on an opposite end be provided with support 3 insulation separately, specifically top end rail 1 is connected with support 3 by an insulation covering 4 respectively with bottom end rail 2 each opposite end; Bottom end rail 2 upper surfaces are set side by side with several frustums 5, frustum 5 shapes and muzzle attachment 6 hydraucone cavity shapes coupling; Corresponding frustum 5 is provided with several through holes on the top end rail 1, through hole is interior to the anode 16 that is arranged with column, the anode 16 outer springs 7 that are arranged with crimping of top end rail 1 lower surface, collets 8 of spring 7 lower end crimping, collets 8 lower ends have a boss 9 that mates with muzzle attachment 6 hydraucone the other end openings, boss 9 highly equals the muzzle attachment 6 muzzle attachment hydraucone the other end endoporus electroless plating position degree of depth, muzzle attachment 6 can be crimped between collets 8 and the frustum 5 under spring 7 effects; Collets 8 inside vertically are provided with for anode and insert the vertical passageway 10 of connection and the interconnection 11 that electrolysis hydrogen overflows.The cross side of through hole is provided with trip bolt 12 on the described top end rail 1, is used for carrying out fastening to the anode 16 that inserts through hole; Described anode 16 lower ends and collets 8 interconnection corresponding positions are provided with crosswise fixed hole 13, after anode 16 inserts collets 8, can pass crosswise fixed hole 13 by iron wire and make between anode and the collets fixing.
Support described in the utility model 3 and upper and lower horizontal 1,2 beams are electrical conductor, and two stands is the making current positive and negative electrode respectively, and by making top end rail 1 for anodal behind insulation covering 4 partitions, bottom end rail 2 is a negative pole.During plating, muzzle attachment 6 is fixed on by spring 7 crimping between the collets 8 of the frustum 5 of bottom end rail and top end rail, forms by frustum 5 and 8 pairs of electroless plating positions of collets simultaneously to intercept.The support that installs muzzle attachment 6 is put in the plating liquid pool, and the horizontal plane of control plating bath is immersed in the electroplate liquid muzzle attachment; The other end of muzzle attachment 6 is that the boss 9 that the electroless plating position of muzzle attachment 6 is insulated piece 8 blocked, and the electroless plating of electroplate liquid and muzzle attachment 6 is partly isolated after the boss 9 of collets 8 lower ends was injected at the electroless plating position.Collets 8, anode 16 and muzzle attachment 6 are electroplated between the position the slit, electroplating solution is electroplated position generation electrochemical reaction with muzzle attachment after flowing to the hydraucone that connects muzzle attachment, the interconnection 11 that the hydrogen of separating out is overflowed by the hydrogen supply gas on the collets 8 is overflowed, and the metal muzzle attachment is electroplated.After the energising, the positively charged ion of electroplating solution moves to power cathode, and electroplating solution negatively charged ion anode moves, though in muzzle attachment endoporus bottom electroplate liquid is arranged also, but the power line when electroplating is insulated the boss of piece following table isolates, so the muzzle attachment endoporus all can not produce coating.The medullary ray of the through hole of the through hole on the top end rail, anode, collets and bottom end rail boss is straight line, guarantees the muzzle attachment workpiece perpendicular to the electroplate liquid plane, and then guarantees galvanized quality.
