Description
Technical field
The utility model relates to reamer field, is specially a kind of anti-chip removal multi knife shaped reamer with interior cooling tube.
Background technology
Reamer is conventional cutting tool, for machining hole.During reaming, from hole wall, cut chip constantly, between reamer and workpiece, severe friction occur simultaneously and produce heat, and the iron filings that reamer cuts cannot be discharged.For avoiding heat accumulation to cause adverse effect and iron filings row not out to the destruction of workpiece and cutter self to cutter and workpiece, now adopt the method heat conduction cooling of spraying cooling fluid to cutter during cutting operation more, and chip removal.This method cooling fluid is the mode adopting direct projection mostly, and cooling effect is undesirable, and chip removal can not arranged and caused downward Integrated Chip, causes cutter breaking, and cooling fluid waste is many.
Utility model content
In order to overcome the defect of prior art, providing a kind of good cooling results, chip removal more thorough, saving the cutter of cooling fluid, the utility model discloses a kind of anti-chip removal multi knife shaped reamer with interior cooling tube.
The utility model reaches goal of the invention by following technical solution:
With an anti-chip removal multi knife shaped reamer for interior cooling tube, comprise cutter hub, it is characterized in that:
The front end face of cutter hub is provided with cutter head lid, and cutter head lid is connected and composed by the connector at middle part by water outlet block and lower cover, and a fabrication hole is respectively established in the both sides of water outlet block, and described fabrication hole is blind hole;
The front portion of cutter hub is provided with knife rest, and the both sides of cutter hub front portion are located at symmetrically by knife rest, and the outer of knife rest and the lateral surface of cutter hub flush, and the rear end of knife rest is provided with flute;
Blade is fixed on knife rest, and the outer of blade is cutting edge, and the cutting edge of blade and the outer of knife rest flush;
Have interior cooling tube in cutter hub, the rear port of interior cooling tube is located on the rear end face of cutter hub, and the front port of interior cooling tube is located on the rear end face of cutter head lid, and the connector of the through cutter head lid of arm is passed through in the front end of interior cooling tube.
The described anti-chip removal multi knife shaped reamer with interior cooling tube, is characterized in that:
The outer of knife rest is spiral yarn shaped or minor arc shape;
Interior cooling tube has two at least, and in every root, cooling tube connects an arm respectively, and the opening of an arm on connector has one at least, and the opening of another root arm on connector has two at least.
When the utility model uses, the utility model is fixed on lathe as on lathe, make the utility model, with workpiece, relative rotation occur, blade of the present utility model cuts from workpiece and forms hole, while cutting, cooling fluid is injected from the rear port of interior cooling tube, is discharged subsequently by arm and connector.The utility model adopts the type of cooling injecting cooling fluid in cutter hub inside, stronger to the cooling effect of cutter hub and blade, adopt the apopore form of at least three direct injections, cooling fluid is directly punched in chip discharge position, and the hole inner chamber avoiding chip inflow workpiece causes workpiece be difficult to cleaning and affect machined surface quality.
The beneficial effects of the utility model are: structure is simple, easy to use, good cooling results, save cooling fluid.
