background technology
Man-hour is added at common production line (production line of cycle 38s) piston annular groove, feed velocity F550, the annular groove axiality of now processing is best, reach below 0.10mm (below technical requirement 0.2mm), but add man-hour at cable release (production line of cycle 33s) annular groove, feed velocity must double and could meet cycle 33s, but the annular groove axiality obtained is limit on the upper side even ultra-specification sometimes, this is because processing feed velocity is too fast, knife bar rolling dynamic deviation reaches 0.10mm, knife bar is larger by shearing stress simultaneously, and in the same side, the resistance causing knife bar to be subject to is larger, cutter is easily made to collapse scarce.In addition, in machining piston pin-and-hole, chamfering needs extra increase by cutter, and tool magazine tool changing adds that separately, chamfer machining at least affects 10s, becomes bottleneck operation, affects the overall processing cycle.
Utility model content
The utility model provides a kind of piston precision to process high-efficiency multi-function cutter, eliminates the shearing stress that annular groove adds man-hour, reduces to add rocking of knife bar in man-hour, improves annular groove axiality and increase chamfering in pin-and-hole simultaneously, realize high-efficiency multi-function.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
Piston precision processing high-efficiency multi-function cutter, comprise the handle of a knife and knife bar that connect successively, be provided with along described cutter spindle to cylindrical side a pair for piston annular groove processing annular groove cutter and a pair for rose reamer in chamfer machining in piston pin hole, wherein interior rose reamer is arranged on the knife bar between described annular groove cutter, and in described in annular groove cutter described in a pair and a pair, rose reamer is all arranged relative to knife bar heteropleural.
The utility model, by arranging annular groove cutter and interior rose reamer on a cutter, realizes carrying out accurately machined object to chamfering in piston annular groove and pin-and-hole simultaneously, shortens the process-cycle, enhances productivity.Annular groove cutter and the equal heteropleural of interior rose reamer are arranged, and eliminate shearing stress when annular groove and interior chamfer machining, reduce to add rocking of knife bar in man-hour, and then improve the precision of annular groove axiality and interior chamfering.
Further, described annular groove cutter and interior rose reamer are along cutter spindle to comprising in the first annular groove cutter, first rose reamer and the second annular groove cutter in rose reamer, second successively, in described first annular groove cutter and first, rose reamer is positioned at homonymy, and in described second, rose reamer and the second annular groove cutter spacing are in homonymy.Make upper and lower interior rose reamer with upper and lower annular groove cutter spacing in homonymy, guarantee adds the shearing stress that man-hour, blade was subject to and can cancel out each other.
Further, described annular groove cutter and interior rose reamer are all connected with described knife bar by the installing hole be opened on knife bar, are provided with alignment pin in this installing hole.Offer the tightening screw for installing holding screw relative to the knife bar side at described position of mounting hole place, this tightening screw is communicated with described installing hole.Said structure design makes blade installation firmly, not loosen, and ensures the precision of processing.
Further, described knife bar offers guiding gutter relative to annular groove cutter and interior rose reamer in position, counter-rotating direction.This guiding gutter can conveniently be discharged adding the iron filings produced man-hour smoothly, avoids iron filings to pile up impact processing operation.
From above technical scheme, the utility model has following beneficial effect:
The shearing stress that when eliminating chamfering in machining piston annular groove and pin-and-hole, blade is subject to, thus reduce to add rocking of knife bar in man-hour, improve processing stability, improve annular groove axiality, ensure that the stability of product quality, realize processing chamfering in annular groove and pin-and-hole simultaneously, shorten the process-cycle, realize high-efficiency multi-function.
