Background technology
The manufacture of engine key components and parts is the process of a complexity and precision, except formulating reasonable, accurate processing technology, it is theoretical and actually deal with problems outside the necessary factors such as technical ability that technologist need possess higher mechanical processing technique, and the making of some aids needed in process is also very important.The blackspot problem of current solution engine cam shaft neck has following two kinds of ways: one controls operation occurs, as improved supporting condition, change efficient cleaner and lubricant medium (as oil cooling), improve and cool flushing pressure and cooling cleannes (as 2um filters), the surface of final guarantee grinding axle journal is without blackspot; Another solves by increasing some links after blackspot produces, and as flash trimmer, polishing machine, automatic or manual clear wiping etc., but said method all exists inefficient problem.
Summary of the invention
The object of the invention is the device proposing a kind of automatic removal camshaft blackspot, to solve the blackspot problem of camshaft journal expeditiously.
The device of automatic removal camshaft blackspot of the present invention comprises at least two and is driven to realize jig arm that is closed and that open by drive unit, and the opposite face of described jig arm is provided with elastic telescopic mechanism, and described elastic telescopic mechanism is provided with poliss.
In the production process of camshaft, under the driving of drive unit, jig arm is utilized to drive the poliss of elastic telescopic mechanism and end thereof by the axle journal of camshaft or the clamping of other position, then in the process of lathe rotating cam axle, the automated cleaning to camshaft can be realized, to dispose the blackspot of camshaft.Owing to being provided with elastic telescopic mechanism especially, radial motion when therefore can eliminate cam axle, on the impact of poliss, makes poliss fit with camshaft all the time, ensures cleaning effect.
Specifically, described elastic telescopic mechanism comprises body and lead, described body is installed in jig arm, described body is provided with guide through hole, one end of described lead is fixedly connected with poliss, the other end is through described guide through hole, and the position that described lead is exposed to guide through hole is provided with the anti-delinking part that diameter is greater than guide through hole diameter; Described lead has spring at the position cover between poliss and body.Moving direction and the distance of poliss can be guaranteed in the anti-delinking part of lead and end thereof, and spring can fit in camshaft surface by utilizing its elastic force to be compressed all the time by poliss.
Further, described body and jig arm are provided with the slide rail of working in coordination, and described body is movably installed in jig arm by slide rail, and body can move relative to jig arm, just can synchronously drive body to move along slide rail during such cam axle, guarantee that poliss is fitted with camshaft all the time.
Further, the both sides of described body are provided with back-moving spring, and one end and the body of described back-moving spring are connected and fixed, and the other end and jig arm are connected and fixed.Back-moving spring can apply reset force to body, impelling body to move to leveling off to the position in camshaft axle center, fitting to impel poliss and camshaft better.
Further, the surface of described poliss is provided with arc-shaped depression portion, to ensure can not depart between poliss and camshaft.
Further, described drive unit is the polishing hoof of cam polishing machine, elastic telescopic mechanism can filter out the radial motion of polishing hoof, only retain the gyration of the opposing cam axle of polishing hoof, therefore need not transform existing cam polishing machine, make full use of existing equipment, can reduce costs, and without the need to extra equipment investment, therefore shared space can not be increased, be very suitable for space and arrange compact production line.
Further, described poliss is made up of installing plate and cellulosic block, like this after use after a while, after wearing and tearing appear in cellulosic block, can change easily, and can not relate to the dismounting of other structure.
The device of automatic removal camshaft blackspot of the present invention, based on existing resource, when cost drops into lower, achieves full-automatic removing camshaft blackspot, has good practicality.
