Abstract
The utility model belongs to the field of machining and particularly relates to a combined type boring cutter. The combined type boring cutter comprises a cylindrical boring cutter rod and a tool bit, wherein the tool bit is connected with the boring cutter rod. A boring blade installation groove is formed in the top end of the tool bit, a first screw through hole is formed in the boring blade installation groove, a chamfering blade installation groove is formed in the middle of the tool bit, and a second screw through hole is formed in the chamfering blade installation groove. The combined type boring cutter further comprises a boring blade and a chamfering blade, wherein the boring blade is matched with the boring blade installation groove, a first through hole is formed in the position, corresponding to the first screw through hole, of the boring blade, the chamfering blade is matched with the chamfering blade installation groove, and a second through hole is formed in the position, corresponding to the second screw through hole, of the chamfering blade. The boring and the chamfering can be simultaneously completed, the coaxiality and the like are improved, and the accuracy is ensured.
Description
Technical field
The utility model belongs to field of machining, especially relates to a kind of combined boring tool.
Background technology
In prior art, while for needs, carrying out the part of bore hole and chamfering, can't disposablely complete, two operations need corresponding cutter head, clamp at twice and could machine it.After changing cutter head, because rigging error easily appears in Renewal process, after repeatedly processing, the form and position tolerances such as its axiality etc. can not be guaranteed, and directly have influence on the precision of part.Owing to changing, cutter head is comparatively loaded down with trivial details, has therefore directly reduced production efficiency.
The utility model content
The purpose of this utility model is to solve the deficiencies in the prior art part, and the combined boring tool of the disposable bore hole of a kind of energy and chamfering is provided.
The purpose of this utility model solves by following technical proposal:
A kind of combined boring tool, comprise cylindrical boring cutter bar and cutter head, described cutter head is connected with boring cutter bar, it is characterized in that: described cutter head top has the bore hole blade installation slot, have screw through-hole one on the bore hole blade installation slot, the cutter head middle part has the chamfering blade mounting groove, has screw through-hole two on the chamfering blade mounting groove; Also include bore hole blade and chamfering blade, the bore hole blade matches with the bore hole blade installation slot, on the bore hole blade with screw through-hole one with respect to place have through hole one, chamfering blade matches with the chamfering blade mounting groove, and place corresponding with screw through-hole two on chamfering blade has through hole two.
The utility model also includes screw one and screw two; Described bore hole blade is fixedly connected with by screw one with the bore hole blade installation slot; Described chamfering blade is fixedly connected with by screw two with the chamfering blade mounting groove.
Cutter head described in the utility model and boring cutter bar are one-body molded.
Compared to the prior art the utlity model has following characteristics and beneficial effect:
1, on cutter, improved, one filling two blades on boring cutter, and the disposable processing that completes bore hole and chamfering, improved its axiality etc., and its precision is guaranteed.
2, do not need to change cutter head, easy and simple to handle, accelerated manufacturing schedule, enhance productivity.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is cutter head place explosive view.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
As shown in Figure 1 and Figure 2, a kind of combined boring tool, comprise cylindrical boring cutter bar 1 and cutter head 2, and described cutter head 2 is connected with boring cutter bar 1.Described cutter head 2 tops have bore hole blade installation slot 3, have screw through-hole 1 on bore hole blade installation slot 3, and cutter head 2 middle parts have chamfering blade mounting groove 5, have screw through-hole 26 on chamfering blade mounting groove 5.
The utility model also includes bore hole blade 7 and chamfering blade 8, bore hole blade 7 matches with bore hole blade installation slot 3, on bore hole blade 7 with screw through-hole 1 with respect to place have through hole 1, chamfering blade 8 matches with chamfering blade mounting groove 5, and place corresponding with screw through-hole 26 on chamfering blade 8 has through hole 2 10.Fill two blades on a boring cutter, the disposable processing that completes bore hole and chamfering, improved its axiality etc., and its precision is guaranteed.
The utility model also includes screw 1 and screw 2 12; Described bore hole blade 7 is fixedly connected with by screw 1 with bore hole blade installation slot 3; Described chamfering blade 8 is fixedly connected with by screw 2 12 with chamfering blade mounting groove 5.After breaks down, screw is backed out, with regard to changeable blade, easy to operate.
