Abstract

The utility model relates to a combined-type cutter for chambering at a duct bottom hole end of a cylinder head. The combined-type cutter comprises a cutter arbor and a cutter blade, wherein a rectangular opening is formed at one end of the cutter arbor; the cutter blade is internally fixed on one surface of the rectangular opening and extends out of the cutter arbor; and a mounting plate is arranged at the other end of the cutter arbor. The combined-type cutter is characterized in that a mounting groove is also formed at the end of the cutter arbor, where the mounting plate is mounted, the mounting groove is formed along the revolution surface of the cutter arbor, a chamfering cutter blade is arranged in the mounting groove, and one end of the chamfering cutter blade is exposed out of the end surface of the cutter arbor, and is adjusted and fixed through an adjustable device. The combined-type cutter provided by the utility model improves the operation safety, reduces the processing procedures, and improves the production efficiency.

Description

Composite cutter

Technical field

The utility model belongs to field of machining, is specifically related to a kind of composite cutter of engine cylinder cover conduit bottom outlet chamfer.

Background technology

As shown in Figure 3, in engine cylinder cover, can stay burr and overlap at the end face of the bottom of tappet bore 11 conduit bottom outlet 10 because of can't chamfering causing, operate when press-fiting conduit at postorder to conduit bottom outlet 10, because burr and overlap are more, the conduit that often causes press-fiting is cut conduit bottom outlet 10 hole walls bad at product rejection, lose bigger, the production scene is in order to satisfy the need of work of postorder, the special work of arranging operating personnel conduit bottom outlet 10 ends to be done chamfering and deburring, so to cover time of hole cost of 16 same features more owing to now produce engine cylinder, make labor intensity of operating personnel improve, influence production efficiency, and scratch than being easier to.

Chinese patent CN201279602Y discloses Superhard composite film aperture boring cutter, belongs to the grinding tool field, is provided with knife bar, and ultra-hard composite blade is along knife bar axis direction welding-on, the mirror polish that blade makes progress.But it does not possess the chamfering function.

The utility model content

The utility model mainly is to solve the end face of existing in prior technology conduit bottom outlet because processing stays the technical problem that burr and overlap cause being difficult to carrying out chamfering etc., a kind of composite cutter is provided, security improves when making operation, has reduced manufacturing procedure, has improved production efficiency.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: it comprises knife bar and blade, described knife bar one end is provided with a right angle opening, be fixed with blade in the face of described right angle opening, described blade stretches out knife bar, the knife bar other end is provided with mounting disc, it is characterized in that, also be provided with a mounting groove at the same end of knife bar, described mounting groove is along the surface of revolution setting of knife bar, be provided with chamfering blade in the described mounting groove, described chamfering blade one end is exposed at outward on the end face of knife bar, and regulates fixing by tunable arrangement.The utility model at blade when removing conduit bottom outlet burr, can carry out chamfering to conduit bottom outlet end face, after having avoided blade to process, need cleaning to stay burr and overlap, and then the conduit bottom outlet carried out chamfering, and chamfering blade of the present utility model can regulate by tunable arrangement, realizes the control of the angle of chamfering flexibly.

As preferably, described chamfering blade adopts Hardmetal materials to be made.

As preferably, 30 ° or 45 ° or 60 ° of the cutting edge of described chamfering blade and the angles between the knife back.

As preferably, described chamfering blade thickness is slightly less than the mounting groove width.

As preferably, the installed surface up and down of described mounting groove is parallel, and is symmetrically distributed.

As preferably, described tunable arrangement comprises housing pin, and described knife bar side is provided with the screw hole that matches with housing pin, and described housing pin is fixed chamfering blade by screw hole.

As preferably, described mounting disc is provided with screw hole.

Therefore, the beneficial effect that the utility model brings is that security improves when making operation, has reduced manufacturing procedure, has improved production efficiency.

The specific embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical scheme of utility model is described in further detail.

Embodiment: composite cutter of the present utility model such as Fig. 1, shown in 2, the blade 6 that comprises knife bar 2 and carbide alloy, knife bar 2 one ends are provided with a right angle opening, in an installed surface of right angle opening, be welded with blade 6, blade 6 stretches out the side and the end face of knife bar 2, also have a mounting groove 7 at knife bar 2 same ends, the installed surface up and down of mounting groove 7 is parallel to the surface of revolution setting of trough with straight angle installed surface along 2 one of knife bars, the installed surface up and down of mounting groove 7 is parallel, be fixed with chamfering blade 1 by tunable arrangement in the mounting groove 7, chamfering blade 1 is made by carbide alloy, chamfering blade 1 part is stretched out the end face of knife bar 2, the cutting edge 8 and the angle reconditioning between the knife back 9 of chamfering blade 1 are at 45, and chamfering blade 1 thickness is slightly less than mounting groove 7 width, and tunable arrangement comprises housing pin 4, be shaped on the screw hole 5 that matches with housing pin 4 on knife bar 2 sides, housing pin 4 is fixed chamfering blade 1 by screw hole 5, and knife bar 2 other ends are connected with mounting disc 3, has four screw holes in the mounting disc 3.

During assembling, the rose reamer blade is packed in the mounting groove 7, housing pin 4 gently is pressed on the chamfering blade 1, mix up the size of stretching out and the angle of rose reamer blade, again housing pin 4 is tightened to start shooting and processed, when size is undesirable, can shut down once more and adjust.
