Description

Thin-wall part processes milling cutter

Technical field

Milling cutter technical field is the utility model is related to, especially a kind of thin-wall part processing milling cutter.

Background technology

Milling cutter, be for Milling Process, there is the rotary cutters of one or more cutters tooth, during work each cutter tooth successively between Cut the surplus of workpiece with having a rest, when to thin-wall part milling, it is necessary to using small chip power, therefore frequently with multiple on such milling cutter Cutter tooth, existing milling cutter are generally formed in one, and after cutter tooth damages, whole milling cutter is also scrapped therewith, and one into The milling cutter manufacture difficulty of type is big, and the requirement to related personnel and equipment is higher.

Utility model content

The technical problems to be solved in the utility model is：In order to solve thin-wall part multitoothed cutter manufacture difficulty in the prior art The problem of big, a kind of thin-wall part processing milling cutter now being provided, the milling cutter for each revolution can be multiple to thin-wall part chip, because This chip power to thin-wall part is smaller.

Technical scheme is used by the utility model solves its technical problem：A kind of thin-wall part processes milling cutter, including Connecting seat and cutterhead, thick axle is provided with the connecting seat, and the thick axle is outward extended with thin axle, the company of the thick axle and thin axle The place of connecing forms step surface, and the inner of the cutterhead is faced out through there is jack, and the thin axle is plugged in the jack, described thin One end end thread of the axle away from thick axle is connected with attachment screw, the cutterhead be located at step surface and attachment screw nut it Between；

The end face outside of the cutterhead circumferentially uniformly offers multiple mounting holes, is offered on the side face of the cutterhead more Individual plane, the plane and mounting hole correspond, and offer the through hole connected with mounting hole in the plane, in the through hole Trip bolt is provided with, the tool rest to match with it is inserted with the mounting hole, the trip bolt is threadedly coupled with tool rest, Knife rest is fixed with by lock-screw on the tool rest, blade is fixed with the knife rest.

Difficulty of processing is greatly reduced by the way that connecting seat, cutterhead, tool rest and knife rest are detachably connected in this programme, when it Conveniently replaced when middle one is damaged, mounting hole opens up the bonding strength that can be improved between tool rest and cutterhead, and assembles It is convenient；Because the difficulty to be drilled on periphery is larger, drill bit is easily damaged or by hole drill piece, on cutterhead its side face in this programme Multiple planes are offered, plane corresponds with mounting hole, drills out the through hole of installation trip bolt in the plane, greatly reduces The difficulty of drilling.

Preferably, the mounting hole has five.

Preferably, it is provided with pad between the end face outside of the cutterhead and the nut of attachment screw.

In order to prevent that cutterhead loosens on connecting seat in milling, machining accuracy is influenceed, further, the connection spiral shell Nail on and be arranged with spring, the spring is located between the nut and pad of attachment screw, by spring attachment screw and carefully Frictional force between the screw thread of axle becomes big, is effectively prevented the loosening that attachment screw occurs in the course of work, ensures that cutterhead exists Steady type on connecting seat.

For the ease of processing and preventing tool rest from being rotated relative to cutterhead, further, the cross section of the mounting hole is in D types.

Further, the outer peripheral face of the thin axle opens up fluted along its axial direction, and the inwall of the jack inwardly prolongs The projection having with the groove match is stretched, the projection is plugged in the groove, is realized by the raised cooperation with groove The transmission of thin power between axle and cutterhead.

In order to improve the bonding strength of tool rest and knife rest, further, the lateral surface of the tool rest is outstanding card article, The neck to match with card article is offered on the knife rest, the card article is fastened in the neck, the tool rest and knife rest it Between be fixedly connected by lock-screw.

The beneficial effects of the utility model are：The utility model thin-wall part processes milling cutter by by connecting seat, cutterhead, knife Seat and knife rest are detachably connected and greatly reduce difficulty of processing, conveniently replaced when one of which is damaged, mounting hole Bonding strength between tool rest and cutterhead can be improved by opening up, and easy to assembly；Multiple planes, plane are offered on its side face of cutterhead Corresponded with mounting hole, drill out the through hole of installation trip bolt in the plane, greatly reduce the difficulty of drilling.
