Description
Technical field
The utility model belongs to the field of machining of metal drilling, and in particular to a kind of drilling machine for deep hole machining.
Background technology
It is small more than 10 or even more than 50 in all kinds of mechanical processing industries, the particularly processing of small deep hole, length diameter ratio
Hole machined is always processing difficulties, is traditionally processed, and can only use spreading fluted drill, common fluted drill exist cooling less than
Position, temperature rise is fast, high problems, and as drilling depth increases, drilling conditions deteriorate rapidly, and drilling can not continue, and processing is deep
Degree is limited；And the necessary withdrawing chip removal of depth for often processing about 1~2 times of diameter, not only machining accuracy is low, surface roughness
Difference, processing efficiency is low, operation labor intensity is big, and quality is difficult to ensure that, does not reach associated specifications, and is easy to cause
" stifled bits " or the drill bit that fractures, cause bigger processing difficulties.
In the case, the drilling principle of drill gun and mode are arisen at the historic moment, and drill gun solves the processing problems of small deep hole,
But because professional drill gun process equipment price is high, processing conditions limitation is more, more to workpiece restrictive requirement, it is unfavorable for vast
Promoted in mechanical processing industry, this technology is popularized in the vast machinery industry practice in China, so as to restrict significantly
The processing efficiency and crudy of small deep hole.
In major part enterprise of China, the problem of running into Small-Deep Hole Machining, full-length drill bit, processing is generally taken to bore
Head, voluntarily the mode of extension drill process step by step.Drilling region can not be directly filled into make up coolant, and can not be normal
The problem of chip removal, entirety can only be taken to exit drill bit frequently, drilling cuttings is cleared up, cool down the mode of drill bit, be then advanced into drilling again,
So as to greatly reduce drilling efficiency；And bore size precision is most preferably only capable of control in 0.2.
To find out its cause, being due to the influence in the intrinsic volume of machine component and processing aperture, deep hole drill is limited most
Major diameter, thus cause its rigidity the bottom of compared with, it is easy to produce the deflection in hole during drilling, and causes resonance, so as to directly affects deep hole
The linearity and surface accuracy of drilling.Meanwhile during gun drilling, the working environment of drill bit is relatively closed and narrow, it dissipates
Heat and chip removal are more difficult, and existing drill bit designs hollow lubrication in order to solve the above problems, often on drill bit
Agent exports, and channel of chip removal, and lubricating and cooling agent outlet makes stiffness of twist drill further reduce, and channel of chip removal then causes drill bit height
Amplitude increase in speed motion, further reduce the linearity of deep hole drilling cuttings.
And then during drill for high-speed, dynamic balancing to deep hole drill structure and cutting stress balance stability requirement compared with
Height, when the quality of processing materials is uneven, two kinds of equilibrium relations are highly vulnerable to breakage, influence the linearity of gun drilling.
Therefore, designing a kind of linearity that can improve gun drilling and the drilling machine of bore size precision has important application
Value.
