The utility model relates to a chromic acid anodization protection frock, can be effectual to steel bushing aluminum shell's guard action during the anodization of realization subassembly chromic acid, and simple structure, the cost is lower.
Description
Technical field
This utility model relates to a kind of chromic acid anodizing protecting tool set-up, particularly relates to a kind of for the chromic acid anodizing protecting tool set-up after steel lining press-in aluminium casing.
Background technology
In operation process, always there is dead eye eccentric wear phenomenon, cause that dead eye sinters in volute part. Therefore the structure for product improves. Consider that part needs to ensure the requirement of axiality in operation process, therefore must 100% this form and position tolerance of guarantee in the course of processing.
First stage: during initial design, it is contemplated that part is easy to process, and some conventional product design methods, the integral material of part is designed as same material (ZL101), adds and be easily guaranteed that this size man-hour, but in properties of product debugging process, owing to part material is aluminum, the bearing material assembled with it is steel, and in product operation process, dead eye wears no resistance, it is easily caused bearing sintering, product cannot run well, therefore, it is necessary to this structure is improved.
Second stage: for preventing the eccentric wear of dead eye, improve the wearability of dead eye, specially the material of both sides dead eye is changed into 30CrMnSiA, increase the wearability in hole, after having pressed set, other size of housing being had impact, and to process guarantee axiality 0.02, difficulty is big especially, quality is unstable, can not 100% ensure axiality 0.02, therefore the program is difficulty with in the course of processing, and working (machining) efficiency is not high.
Phase III: working (machining) efficiency should be improved, ensure the serviceability of product again, the probability size according to eccentric wear, change �� 47 Porous materials into 30CrMnSiA, for better ensureing axiality, it is necessary to after part complete machining is complete, just can carry out chromic acid anodizing.
The difficult point of the work flow after improvement is in that after having pressed steel bushing to be needed to ensure that steel aluminum bi-material carries out chromic acid anodizing simultaneously; in addition steel bushing is had certain corrosiveness by chromic acid anodizing liquid; in chromic acid anodizing process, difficulty of processing increases, it is therefore necessary to design a set of special protecting tool set-up.
Utility model content
In order to solve in background technology existing technical problem, the utility model proposes a kind of chromic acid anodizing protecting tool set-up, it is possible to protective effect to steel sleeve aluminum enclosure when effectively realizing assembly chromic acid anodizing, and simple in construction, less costly.
Technical solution of the present utility model is: a kind of chromic acid anodizing protecting tool set-up, it is characterized in that described protecting tool set-up includes frock lining, frock ring set, frock nut and sealing ring, described frock lining is step lining, the big end end face of frock lining arranges end face annular groove, the bar portion of frock lining arranges circumferential groove in its end portion, having axially extending bore in the middle of frock lining, the afterbody in bar portion has screw thread; Frock ring set is enclosed within bar portion, and frock nut screws the connection realized on screw thread with frock lining; Described sealing ring is two, and the first sealing ring is located in frock bush end face and is attached to surface of shell; Second sealing ring is located at frock lining sleeved rod portion and is attached to shell inner hole surface.
The cylindrical of above-mentioned frock lining sleeved rod portion right-hand member is provided with multiple rows of circumferential aperture.
Above-mentioned frock ring set cylindrical is provided with multiple rows of radial hole, it is achieved the abundant circulation of electrolyte.
Above-mentioned frock lining realizes the connection with housing by frock ring set and frock nut, it is ensured that housing part hole inner chamber realizes chromic acid anodizing.
Above-mentioned first sealing ring is located in the end face annular groove of the big end of frock lining, and the second sealing ring is located in the circumferential groove in its end portion of frock lining sleeved rod portion, it is achieved steel lining will not by electrolytic corrosion.
The beneficial effects of the utility model: this utility model chromic acid anodizing protecting tool set-up process structure is simple; easy to operate, laborsaving save time, reliability higher; less costly; during chromic acid anodizing, chromic acid solution can circulate fully; not only steel sleeve is achieved and be effectively protected; it is simultaneously achieved the chromic acid anodizing of aluminium casing, there is bigger practical value.
