Abstract

The utility model discloses a drilling reamer which comprises a knife handle and a knife head, wherein the knife head is arranged at one end of the knife handle. The knife head includes two drilling blades and two hinging blades, the rear ends of the two drilling blades are provided with a first guiding portion and a second guiding portion, the two drilling blades integrate with the first guiding portion and the second guiding portion, and the two hinging blades are mounted on the rear ends of the first guiding portion and the second guiding portion. The drilling reamer has long service life, and high working accuracy. The knife head is utilized by combing a drill and hinging blades so as to complete working task once and reduce a procedure. A blade with fine finish is added on the drill so that the driller is ensured to have a reaming function, and is capable of saving manpower, improving efficiency, and greatly reducing production cost.

Description

A kind of drilling reamer
Technical field
The utility model relates to a kind of machining tool, particularly a kind of drilling reamer.
Background technology
At present, also increasingly high because design level is increasingly high to the specification requirement of processing parts, the hole of the various high-precision requirement of ubiquity processing in the mechanical part processing.Because the having relatively high expectations of aperture all is to adopt boring earlier usually, reaming again, finish ream, to reach high-precision requirement.
Want to obtain the hole of an IT7 level, generally need to bore and the hinge two procedures, the effect of drill bit is to bore bottom outlet, and reamer guarantees dimensional tolerance and roughness.Numerous and diverse like this step, both wastes of manpower delay man-hour again, and production cost is increased substantially, and in the process that repeats operation, the precision of fraising is difficult for holding.
The utility model content
The purpose of the utility model provides a kind of drilling reamer, and this cutter had both improved efficient, has practiced thrift cost again.
The technical scheme that adopts is:
A kind of drilling reamer comprises handle of a knife and cutter head, and cutter head is installed in handle of a knife one end;
Cutter head comprises two pieces of drill lips and two pieces of hinge swords; Two pieces of drill lip rear ends are respectively arranged with first guide part and second guide part; And two pieces of drill lips are an overall structure with first guide part and second guide part respectively, and two pieces of hinge swords are installed in first guide part and the second guide part rear end (see figure 2) respectively;
First groove that forms between above-mentioned two pieces of drill lips and the two pieces hinge sword is respectively first chip area and second chip area;
Form second groove respectively between above-mentioned two pieces of drill lips and first guide part and second guide part.
The advantage of the utility model is:
The utility model long service life, machining accuracy is high, the cutter head that adopts drill bit and reamer to combine; One-stop operation just can be accomplished processing tasks, reduces one procedure, on drill bit, adds a fine finishining sword; Guarantee that drill bit has the function of ream, not only save manpower but also raise the efficiency, reduce production cost significantly; And can better produce a desired effect, can reach the effect of ream.

Fig. 2 is the cutter head schematic cross-section of the utility model.
The specific embodiment
A kind of drilling reamer comprises handle of a knife 1 and cutter head, and cutter head is installed in handle of a knife 1 one ends;
Cutter head comprises 2,3 and two pieces of hinges of two pieces of drill lips sword 4,5; Two pieces of drill lip 2,3 rear ends are respectively arranged with first guide part 6 and second guide part 7; And two pieces of drill lips 2,3 are an overall structure with first guide part 6 and second guide part 7 respectively, and two pieces of hinge swords 4,5 are installed in first guide part 6 and second guide part, 7 rear end (see figure 2)s respectively;
2,3 and two pieces of hinges of above-mentioned two pieces of drill lips sword 4, first groove that forms between 5 are respectively first chip area 8 and second chip area 9;
Form second groove 10 respectively between the above-mentioned two pieces of drill lips 2,3 and first guide part 6 and second guide part 7.
