Description
Technical field
The utility model relates to a kind of electroplating device, and particularly a kind of marine diesel piston head is electroplated tooling device.
Background technology
Piston head is one of important component part of oil motor, in order to strengthen the wear resistance of its upper piston annular groove, need carry out chromium plating to the upper and lower surfaces of annular groove and handle.Annular groove is many narrow grooves that are distributed in the piston head cylindrical surface, and its groove width generally is 8～20 millimeters, and groove depth is generally 12～18 millimeters, can reach 26 millimeters the most deeply.Owing to receive the influence of groove structure, adopt the common anode plate to utilize the method for quiet plating to electroplate piston ring groove, because the distance difference between negative electrode (piston) and the positive plate do not wait, cause on the negative electrode distribution of current inhomogeneous.The final thickness of coating that obtains is inhomogeneous, even can not plate chromium at the annular groove inner surface; And the coating adhesion that plates chromium is relatively poor, coating peels off easily, and hardness is low, has defectives such as pore.Therefore needs are a kind of now can solution to the problems described above or electroplanting device.
Summary of the invention
The utility model is in order to solve the above-mentioned deficiency of existing in prior technology; Propose a kind of simple in structurely, design ingeniously, can guarantee that thickness of coating is even; Strong adhesion, hardness height, the marine diesel piston head of defectives such as chromium coating no longer includes and peels off, pore is electroplated tooling device.
The technical solution of the utility model is: a kind of marine diesel piston head is electroplated tooling device, comprises plating tank 1, it is characterized in that: through rotating shaft 2 lateral brace piston head 3 is arranged in the described plating tank 1; The part that rotating shaft 2 is connected with plating tank 1 is provided with hydrops groove 4 and axle envelope 5; Also be provided with conducting ring 6 in the rotating shaft 2, rotating shaft 2 links to each other with the working end of drive-motor 8 through transmission pair 7, is provided with positive plate bracing frame 9 in the upper end of plating tank 1; The lower end of positive plate bracing frame 9 is provided with a plurality of pictograph positive plates 10; Pictograph positive plate 10 semicirculars in shape, and be suspended from the annular groove 11 of piston head 3, also be provided with para tape balancing weight 12 in the bottom of plating tank 1; It is provided with a plurality of PVC para tapes 13 that match with pictograph positive plate 10 quantity, and PVC para tape 13 is socketed in the annular groove 11.
Described pictograph positive plate 10 is provided with plated support part 14, and the both ends of the surface of plated support part 14 equate apart from the distance of pictograph positive plate 10.
The utility model is compared with prior art, has following advantage:
The plating tooling device of this kind of structure formation; To existing plating equipment existing problem in the electroplating process that carries out the piston head annular groove; Promptly owing to do not waited by the range difference of electroplating parts and positive plate distance; So often cause thickness of coating inhomogeneous even do not electroplate, and the mechanical property of coating is also relatively poor.In order to address this problem; Design (promptly semicircular) the pictograph positive plate that matches with the piston head shape now; And in galvanized process, let piston head uniform rotation under the effect of drive unit, guarantee that pictograph positive plate and institute plate various piece partly apart from equalization, it is even that this plating tooling device can obtain thickness; Strong adhesion, the chromium coating that hardness is high, and chromium coating no longer includes defectives such as being prone to peel off, having pore.Therefore we can say that it has possessed multiple advantage, be particularly suitable for applying in the art that its market outlook are comparatively wide.

Embodiment
Below with the embodiment of accompanying drawings the utility model.Like Fig. 1, Fig. 2, shown in Figure 3: a kind of marine diesel piston head is electroplated tooling device; Comprise plating tank 1, be perfused with electroplate liquid in the plating tank 1, in plating tank 1, be provided with piston head 3 through rotating shaft 2 lateral brace; The part that rotating shaft 2 is connected with plating tank 1 is provided with hydrops groove 4 and axle envelope 5; Prevent that electroplate liquid from flowing out from the two seam crossing, rotating shaft 2 is provided with conducting ring 6, and the end of rotating shaft 2 links to each other with the working end of drive-motor 8 through transmission pair 7; Upper end at plating tank 1 also is provided with positive plate bracing frame 9, then is provided with a plurality of pictograph positive plates 10 in the lower end of positive plate bracing frame 9, pictograph positive plate 10 semicirculars in shape, and the annular groove 11 of its shape and piston head 3 matches; And pictograph positive plate 10 is suspended in the annular groove 11, and pictograph positive plate 10 is provided with insulating plated support part 14, and the distance of two end face distance pictograph positive plates 10 equates about plated support part 14; Be provided with para tape balancing weight 12 in the bottom of plating tank 1, para tape balancing weight 12 is provided with a plurality of and pictograph positive plate 10 (promptly with annular groove 11) the PVC para tape 13 that quantity matches, and these PVC para tapes 13 are socketed in the annular groove 11.
The working process that the marine diesel piston head of this kind of utility model embodiment is electroplated tooling device is following: the upper end that at first pictograph positive plate bracing frame 9 is buckled in plating tank 1; Let pictograph positive plate 10 be suspended in each annular groove 11; Under the effect of plated support part 14, pictograph positive plate 10 is consistent with the distance of annular groove 11 both ends of the surface basically; Start drive-motor 8 then, drive-motor 8 drives rotating shafts 2 through transmission pair 7 and rotates, and the piston head 3 that is arranged on rotating shaft 2 one ends rotates thereupon; Pictograph positive plate 10 energisings simultaneously; Piston head 3 as negative electrode is also switched on, and under the effect of electrolysis principle, the chromium ion in the electroplate liquid just can be on two end faces about annular groove 11 (under state as shown in Figure 1; Two end faces about being; Be two end faces up and down under piston head 3 working ordeies) form chromium coating, do not need the face of coating then to be wrapped, the high Current Zone that it can shielded cathode by PVC para tape 13; Because pictograph positive plate 10 is identical apart from the left and right sides end face distance of annular groove 11 in galvanized process; And piston head 3 is under the state of uniform rotation; Therefore big or small the having equal opportunities of distribution of current on the annular groove 11; Can obtain the uniform coating of thickness, and the coating adhesion that utilizes this device to obtain is strong, hardness is high, has eliminated defectives such as being prone to peel off, having pore.
