Technical field
The present invention relates to a kind of boring machine, Cutter Body Processing with Machining Center cutter, specifically a kind of high rigidity micrometer adjustement boring tool.
Background technology
Boring cutter is one kind of cutting tool for boring, has one or two cutting tip, dedicated for existing hole is carried out slightly plus
Work, semifinishing or polish.Boring cutter can use on boring machine, machining center or milling machine.
The method that the adjustment of boring cutter does not typically adopt artificial trial cut, so the adjustment before processing just seems extremely important.Adjust
Size after whole accurately must will adjust the lower limit in processed hole tolerance, and considers the influence factor of temperature etc., is repaiied
Just, compensate.Cutter adjustment by workman's manual operations, or can be carried out on tool setting device or other amounts instrument on special presetting instrument, machine.But
These toolsetting methods all have the shortcomings that time-consuming, laborious, high labor intensive, high to operative employee's technical requirements.
For overcoming these shortcomings, improve work efficiency, modern industry is often adopted on jig boring machine, transfer matic and Digit Control Machine Tool
With micrometer adjustement boring tool, common pattern has screw-type micrometer adjustement boring tool, the small adjustment eccentric borer, chute-type double-blade boring cutter and floating boring
Knife etc..These micrometer adjustement boring tools differ from one another, more convenient than traditional boring cutter toolsetting when using in actual production, and production efficiency is high.But
These micrometer adjustement boring tool complex structures, operation inconvenience, the fine tuning structure that it increases will be low to the rigidity making cutter head, turns round and look at this mistake
That, have impact on machining accuracy.

For fastening the holding screw of described boring cutter bar；
Described boring cutter bar is square pole, and its inner end face has an inclined-plane I；
Described handle of a knife outer end end face has a counterbore being communicated to boring cutter bar, is provided with regulation skewback in counterbore；Described
Adjust skewback the inner and have the inclined-plane II coordinating with boring cutter bar inclined-plane I, adjust skewback outer end end face and have a screw-threaded counterbore；
It is fixed with plug screw in handle of a knife counterbore outer end, in the middle of plug screw, have a through hole；
Adjusting screw rod is provided with described plug screw, in adjusting screw rod insertion plug screw through hole, adjusting screw rod is inner and adjusts
Skewback screw-threaded counterbore connects；Dividing on the nut of adjusting screw rod outer end has scale；
It is provided with spring between described plug screw and regulation skewback.
It is further：It is close to described plug screw the inner and is provided with a circlip for shaft, circlip inner ring is stuck in described tune
On section screw rod.
Described holding screw totally two, is in 90 ° of arrangements each other.
The method have the advantages that：Using fine thread and inclined-plane combination governor motion so that the degree of regulation of boring cutter is higher；
Adjust operating position on the end face of handle of a knife, adjust convenient；The mounting means of boring cutter bar ensure boring cutter bulk strength and
Rigidity is high, improves machining accuracy；Overall structure is simple, and processing and manufacturing is easy.
