Sleeve, the upper center lead to liquid plate level and are arranged on endoporus sleeve, and the lower center leads to liquid plate level and is arranged on outer sleeve, described
Anode for chrome-plating is vertically arranged in inside cylinder barrel, and the upper end of anode for chrome-plating and upper center lead to liquid plate centre bore fit closely, under
End leads to the tight fit of liquid plate centre bore with lower center；
Two threaded holes are provided in the endoporus sleeve, two screws pass through the threaded hole of cylinder barrel wall and endoporus sleeve by cylinder
Cylinder is fixed with endoporus sleeve connection；
The upper center leads to liquid plate and to lead to liquid plate uniformly distributed multiple convenient for bath flow in respective centre bore surrounding at lower center
Through-hole.
The 1/10-1/ that the annode area of the anode for chrome-plating is the 1/2-1/3 of cathode area, anode diameter is internal diameter of cylinder
5。
The upper center leads to liquid plate and lower center leads to liquid plate making material for polytetrafluoroethylene (PTFE).
The endoporus sleeve, outer sleeve making material are 45# steel.
Compared to the prior art the utility model has the advantages that.
First, the utility model leads to liquid plate by upper center and lower center leads to liquid centre bore and anode for chrome-plating is fitted close, real
The positioning of anode for chrome-plating now heavier to itself is fixed, and chrome-plating process anode for chrome-plating is avoided not wave, loosen, influences chromium plating.
2nd, upper center described in the utility model leads to liquid plate and lower center leads to liquid plate making material selection polytetrafluoroethylene (PTFE), energy
It is enough to be dielectrically separated from anode for chrome-plating and cylinder barrel, it avoids the occurrence of and blows hanger or product is electrically shocked the accident of damage.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model.
In figure, 1 is endoporus sleeve, and 2 lead to liquid plate for upper center, and 3 be cylinder barrel, and 4 be anode for chrome-plating, and 5 lead to liquid plate for lower center,
6 be outer sleeve.
Specific embodiment
As shown in Figure 1, a kind of inner hole of cylinder hard chromium plating device, leads to liquid plate 2, anode for chrome-plating including endoporus sleeve 1, upper center
4th, lower center leads to liquid plate 5 and outer sleeve 6；
The endoporus sleeve 1 is sleeved on vertical 3 one end of cylinder barrel, is set in the other end of cylinder barrel 3 and is fitted close with cylinder barrel 3
Outer sleeve 6, the upper center leads to liquid plate 2 and is horizontally set on endoporus sleeve 1, and it is horizontally disposed outside that the lower center leads to liquid plate 5
Sleeve 6, the anode for chrome-plating 4 are vertically arranged in inside cylinder barrel 3, and the upper end of anode for chrome-plating 4 leads to 2 center of liquid plate with upper center
Hole fits closely, lower end leads to the tight fit of 5 centre bore of liquid plate with lower center；
It is opened in the endoporus sleeve 1 there are two threaded hole, two screws pass through the threaded hole of 3 wall of cylinder barrel and endoporus sleeve 1
Cylinder barrel 3 is connect fixation with endoporus sleeve 1；
