The utility model discloses an utilize brill sword, reamer and compound formula structure as an organic whole of chamfer, change two original or even three sword processing into a sword processing, realize once only accomplishing, drilling, reamed hole, positive and negative chamfer process, the error that secondary location when having avoided the tool changing appears, the processing back hole obtains better hole position degree, saves one set of handle of a knife and appurtenance, reduces the purchasing cost of cutter.
Description
Technical Field
The utility model belongs to the technical field of the cutter, concretely relates to three sword bores reamer.
Background
At present, when a step hole is machined, a drill bit is generally used for hole machining, then a reamer is used for finish machining, and then a chamfering tool is used for spot facing, so that the machining process is complex, two or even three tools are possibly needed for operation and machining, tool changing is frequent, the working efficiency is low, and a secondary positioning error caused by tool changing is easy to occur, so that the problem is solved by providing a three-edge drill reamer.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a three sword reamer to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the three-edge reamer comprises a reamer body, wherein the reamer body is of a three-section stepped structure and comprises a first small end part, a second middle end part and a third large end part, the first small end part is the tip part of the reamer body, the second middle end part is arranged at one end of the first small end part, the second middle end part is a reamer part and is provided with a three-edge reamer, the third large end part is arranged at one end of the second middle end part, and a chamfer groove is fixedly formed in one side, which is a chamfer part and is the third large end part, of the third large end part.
Preferably, the first small end part, the second middle end part and the third large end part are of an integrated structure, and the third large end part is the tail part of the cutter body.
The arrangement can combine the drill, the reamer and the chamfer angle on one cutter, and is convenient to finish at one time.
Preferably, the first small end part is a drill part provided with spiral cutting edges, and spiral chip removing grooves are formed between adjacent spiral cutting edges.
The spiral cutting edge is arranged, so that drilling and cutting operations are facilitated.
The utility model discloses a technological effect and advantage: this three sword reamer utilizes brill sword, reamer and chamfer compound formula structure as an organic whole, and two or even three sword processing that will be original are changed into a sword processing, realize once only accomplishing, and drilling, reaming, positive and negative chamfer process have avoided the error that secondary positioning when the tool changing appears, and the hole obtains better hole position degree after the processing, saves the resource, effectively improves work efficiency.
