Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
In electroplating process, giving the size of electric current is a very important technic index in electroplating process, and the success or failure of some plating are even decided by whether can provide enough large electric current.But due to current characteristics determine super-large current give electric process, be all to there is very high difficulty, and if in electroplating process need rotation electroplate, its give electric difficulty further strengthen.In the utility model, provide be exactly a kind of super-large current electroplate to electric installation, its main technological improvement comprises: described comprising puopulsion unit 1, rotation to electricity seat 2 and stretch to electric installation forms to electric installation 3, described puopulsion unit 1 is given electricity seat 2 and is stretched with rotation and is connected to electric installation 3, and above-mentioned parts are installed on same axis, and puopulsion unit 1 is relatively simple for structure, the structure that can adopt cylinder or hydro-cylinder, realizes promotion.Described stretching mainly comprises main shaft 4 to electric installation, end cover 5 forms to electric piece 10 with stretching, on described end cover 4, be provided with spindle hole 7, main shaft 4 is arranged in this axis hole 7, in spindle hole 7, be provided with sealing-ring, so that the gap between sealing main shaft 4 and spindle hole 7, on above-mentioned end cover 5, be also connected be sleeved on main shaft give electric block 8, end cover 5 generally can be changed, its size is mainly to match with the workpiece of needs sealing, generally electrolytic solution is sealed in workpiece, stretching in the utility model mainly used in being coated with of tubing to electric installation.Described giving on electric block 8 sidewalls is provided with more than one through hole 9, in this through hole 9, be provided with and stretch to electric piece 10, stretching to the below of electric piece 10 is inclined-plane 11, on main shaft 4 with stretch to electric piece 10 correspondence positions be provided with one with to the inclined-plane 11 that matches, electric piece inclined-plane, can realize under the promotion of puopulsion unit, utilization is stretched to electric piece 10 with to the inclined-plane 11 below electric piece, can realize makes to stretch carries out expanding-contracting action to electric piece 10, generally above-mentioned main shaft 4 and the metal that has excellent conductive performance to electric piece 10 employings that stretches are made, for example: copper, aluminium etc.Described stretching is arranged on the both sides of main shaft 4 to electric piece 10 correspondences, hold this stretch to the through hole 9 of electric piece 10 to same corresponding setting on electricity seat 8.Like this in starting under puopulsion unit effect when main shaft 4 to promote forward, stretch to can't the moving of electric piece 10 itself, but stretch out laterally under the effect on inclined-plane 11, until hold out against on the workpiece inwall of tubulose.Described rotation is contained in to electric cover for seat on the main shaft 4 in end cover outside, and be connected to electric installation with puopulsion unit and rotation, rotation is provided with cavity to electricity seat 2 middle parts, wherein be filled with low melting point metal, generally can adopt mercury as packing material, rotation is revealed to prevent water silver to being provided with sealing-ring between electricity seat 2 and main shaft 4.
Puopulsion unit in the utility model has two kinds of fixed forms, and one is that described puopulsion unit 1 is fixed on end cover 5 by support.It two is fixed on the permanent seat of insulation for described puopulsion unit.As can be seen from the above description, as long as puopulsion unit and rotation are fixed as one to electric installation and main shaft, so that and realize and relatively moving between sealing cover and workpiece, under the effect that so just can guarantee to stretch to electric piece 10 puopulsion units 1, stretch to electric process.Therefore rotation described in the utility model just can realize to electric process be electrically connected to electricity seat 2 with power supply after.
First working process of the present utility model for utilizing end cover 5 that workpiece one end is sealed and fixed, the workpiece of tubulose is just combined into as a whole with workpiece like this, at this moment start puopulsion unit, drive connects into as a whole rotation and advances to electric installation and main shaft, the inclined-plane being arranged on like this on main shaft travels forward with main shaft, at this moment inclined-plane will push stretching also protruding to electric piece 10, know on the workpiece inwall that is tightly fitted in tubulose, at this moment making current and start rotation electroplate, due to workpiece at this moment, end cover 5, main shaft 4 rotates together with electric installation with a part of rotation, electric current has the rotation of other half to conduct electrical currents on workpiece by mercury to electric installation.Because rotation is to the metal that is full of mercury or other low melting points in electric installation, in above-mentioned rotary course, still can keep rotation to thering is extraordinary electrical connection between electric installation.Thereby realize reliable and stable super-large current power supply.
Described above is only preferred embodiment of the present invention, and above-mentioned specific embodiment is not limitation of the present invention.In technological thought category of the present invention, can there is various distortion and modification, retouching that all those of ordinary skill in the art make according to above description, revise or be equal to replacement, all belong to the scope that the present invention protects.
