Abstract
The utility model discloses a cutting tool, which comprises a cutter head with a wider head and a narrower body, a lug is arranged on the top end surface of the head, and the lug is used for arranging the tip of the cutting head. The embedded effect is enhanced through the concavo convex coordination between the tip of the cutter head and the cutter head, therefore, the tip of the cutter head is uneasy to fall off, and the service life is long.
Description
Technical field
The utility model relates to a kind of cutter, and this cutter can be installed on road planer, various rotary drilling rig tool or the milling tool, mainly scrapes pavement of road, cutter boring the ground product, holes or carries out the surface roughness processing in order to plane.
Background technology
In the cutter head of the cutter of prior art, cutter head has structure wide at the top and narrow at the bottom, welded and installed has the cutter head tip on the top end face of broad head, this top end face generally is smooth shiny surface, the cutter head tip is mounted in stable bad on the cutter head like this, cause the cutter head tip to come off easily in use, application life is short.
Summary of the invention
The purpose of this utility model provides a kind of cutter, and the cutter head tip stably is mounted on the cutter head of cutter.
For achieving the above object, the technical solution adopted in the utility model is: a kind of cutter, and it comprises cutter head, described cutter head has the head of broad and narrower body portion, the top end face of described head is provided with projection, and described projection is used for installing the cutter head tip thereon.
Offer groove on the top end face of described head, described projection places in the described groove, and described groove is used to accommodate the bottom of cutter head tip.
Described projection is the round fixture block that is convexly equipped with in described groove central authorities.
Because the utilization of technique scheme, the utlity model has following advantage: the top end face of cutter upper slitter head portion is provided with projection, this projection is used for being equipped with the cutter head tip thereon, between cutter head tip and the cutter head concavo-convex the cooperation to increase the build-in effect, cutter head tip difficult drop-off in use like this, long service life.

The specific embodiment
Further set forth structure of the present utility model below in conjunction with accompanying drawing.
Shown in accompanying drawing 1-3, cutter integral body comprises the pad 7 that a cutter head 1, wide at the top and narrow at the bottom is set in packing cover 6 and one loop shaped in this cutter head 1 body portion 3.Cutter in use, a cutter head tip can be welded in the top of cutter head 1, brill etc. is scraped or cuts a hole in this cutter head tip in order to plane, this cutter head 1 has the head 2 of broad and narrower body portion 3, in the present embodiment, head 2 is tilted cone shape, body portion 3 is roughly cylindrical, offer groove 5 on the top end face of head 2, this groove 5 is used to accommodate the bottom of cutter head tip, and the projection 4 that protrudes on the top end face of head 2 places in the groove 5, and this projection 4 is used for installing the cutter head tip thereon, for attractive in appearance, the projection 4 in the present embodiment is for being convexly equipped with the round fixture block in groove 5 central authorities.In use, the cutter head tip is installed on the round fixture block, as shown in Figure 4, between cutter head tip and the cutter head 1 concavo-convex the cooperation to increase the build-in effect, cutter head tip difficult drop-off in use like this, long service life.
As sectional view Fig. 2 and shown in Figure 3, be concaved with a concave ring part 8 in this cutter head 1 body portion 3, this packing cover 6 has a plurality of blocking parts 9 that protrude into this concave ring part 8, this blocking part 9 matches with concave ring part 8 to prevent that this packing cover 6 from deviating from cutter head 1, and make cutter cutter head 1 when work in this packing cover 6, stably to rotate, cutter head 1 inserts in the tool rest by packing cover 6 when mounted, the accepting hole of packing cover 6 and tool rest interference fit mutually wherein, pad 7 is set in the periphery of packing cover 6, pad 7 has the through hole that an annular groove 10 and connects this annular groove 10, the inwall of through hole protrudes the lead angle of pair of opposing and reverse symmetry, the cross section that is packaged in the packing cover 6 in the body portion 3 of cutter head 1 is the C type, as shown in Figure 1, a lead angle is stuck in the C type breach of packing cover 6, another lead angle is stuck in the recess of packing cover 6, packing cover 6 and pad 7 all are steel matter, this pad 7 by lead angle be stuck in packing cover 6 around, this pad 7 is with this packing cover 6 expanded support radially, pad 7 overlaps 6 axial slip under external force along packing in use, the head 2 that moves to broad offsets, this head 2 is tilted cone shape, outer peripheral face is provided with most and protrudes and be wavy symmetrical lines, and wavy lines tail end is equipped with the train of dress portion of a declivity on the head 2, the bottom of this train of dress portion is connected with the end T-Ring that is circular-arc, the shape of the annular groove 10 on this pad 7 is consistent with the lower limb of this end T-Ring, make when being installed on cutter on the plane rig tool, end T-Ring is coincide in the annular groove 10 that is embedded in pad 7, use and make cutter head 1 under mode of operation, can keep the stable middle rotation of putting, and the friction that contacts of minimizing and tool rest, to increase the application life of cutter head 1.
