Abstract
The utility model relates to the diamond electroplating field and discloses a tool fixture for an electroplating bowl-shaped grinding wheel. The tool fixture comprises a lampshade-shaped small hole fixture and a lampshade-shaped big hole fixture for clamping the internal taper surface of a bowl-shaped grinding wheel base body respectively. When being used for electroplating the bowl-shaped grinding wheel, the tool fixture has the advantages that non-uniform appearance caused by point discharge is improved, and meanwhile, a plating layer has uniform thickness.
Description
Technical field
The utility model relates to the diamond electroplating field, especially relates to a kind of bowl frock clamp of molding sand wheel of electroplating.
Background technology
In the diamond electroplating process of traditional bowl type (inner conical) emery wheel, because shape of product complexity, will be on the inner conical face diamond (median size 0.055mm) composite plating, the performance of point discharge feature is particularly outstanding, tip or marginal discharge are big characteristics of plating itself, be that workpiece geometrical factor and power line have determined distribution of current inhomogeneous, show as the inhomogeneous of thickness of coating simultaneously.Thereby make whole thickness of coating difference, make that the imbed rate difference of diamond in coating is bigger, have influence on quality product.
Summary of the invention
At problem set forth above, the utility model purpose is to provide a kind of coating to electroplate bowl frock clamp of molding sand wheel uniformly.
The utility model realizes that by following technical measures a kind of bowl frock clamp of molding sand wheel of electroplating comprises clamping lampshade shape aperture anchor clamps and the lampshade shape macropore anchor clamps that the bowl molding sand is taken turns the inner conical face of matrix respectively.
Concrete, the diameter of the aperture of described lampshade shape aperture anchor clamps be the bowl molding sand take turns the matrix external diameter 1/4 to 1/3 between.
Concrete, the diameter of the aperture of described lampshade shape macropore anchor clamps is 1/2 of a bowl molding sand wheel matrix external diameter.
Concrete, the tapering of the inner conical face of described lampshade shape aperture anchor clamps and lampshade shape macropore anchor clamps matches with the tapering of the inner conical face of bowl molding sand wheel matrix.
A kind of optimal way, the tapering of the inner conical face of described lampshade shape aperture anchor clamps, lampshade shape macropore anchor clamps and bowl molding sand wheel matrix all is 108 degree.
Concrete, the back side of described lampshade shape aperture anchor clamps is provided with one can clamp the groove that the bowl molding sand is taken turns the inner conical face of matrix.
Concrete, the back side of described lampshade shape macropore anchor clamps is provided with one can clamp the groove that the bowl molding sand is taken turns the inner conical face of matrix.
During plating, use the plastic tank plating tank to be used for holding electroplate liquid, nickel plate (anode) is gone up punching and is hung over the two symmetrical inwalls (under the plating liquid level) of plating tank with the titanium bar, and guide line connects the positive pole of power supply on the titanium bar.Fluffy being placed on the plating tank of one rod (hanger rod), the main shaft of two rope slings (hanger rope) string after suspention assembling on the hanger rod, frock after the whole assembling and matrix are hung under the plating liquid level, draw lead one end and connect with matrix, the negative pole of the other end and power supply links.During plating, electric current is introduced nickel anode from direct supply through outer conductor, introduces negative electrode (gear matrix) again through plating bath, comes back to direct supply through lead again then, constitutes electric loop.
The utility model electroplated diamond zone is on inner conical surface, and the bore gap is big up and down, and thickness uniformity of electroplated layers will lean on lampshade shape aperture anchor clamps and lampshade shape macropore anchor clamps auxiliary mould to carry out twice shielding thickening stage by stage.
Preplating I=0.35A, t=20min,
Plant sand I=0.2A, t=20min/ time 2 times, (mouth is manually planted sand, same preplating up),
Thickening I=0.45A adds a cover lampshade shape aperture anchor clamps behind the t=30min.
I=0.25A adds a cover lampshade shape aperture anchor clamps behind the t=70min.
After using the utility model, the problem of the high position district nickel plating at first of bowl molding sand wheel matrix inner conical face has obtained shielding, and the coating uniformity of whole high low level is improved, and quality product is guaranteed.
