Description

A kind of drill gun system of Small-Deep Hole Machining

Technical field

The utility model belongs to field of machining, and in particular to a kind of drill gun system of Small-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, and common fluted drill, which exists, to be cooled down not in place, and temperature rise is fast, high problems.As drilling is deep Degree increase, drilling conditions deteriorate rapidly, and drilling can not continue, and working depth is limited, and often process the depth of about 1~2 times of diameter The necessary withdrawing chip removal of degree, not only machining accuracy is low, surface roughness is poor, and processing efficiency is low, operation labor intensity is big, and quality is difficult to Ensure, do not reach associated specifications, and be 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 its technology is increasingly perfect, and this problem obtains Preferably solve.But because professional drill gun process equipment price is high, processing conditions limitation is more, more to workpiece restrictive requirement, no Promoted beneficial in vast mechanical processing industry, this technology is popularized in the vast machinery industry practice in China, from And the processing efficiency and crudy of small deep hole are constrained significantly.

In major part enterprise of China, Similar Problems are run into, full-length drill bit, processing drill is generally taken, voluntarily connects The mode of long drill bit is processed step by step.Can not directly be filled into drilling region to make up coolant, and can not normal chip removal difficulty Topic, 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 significantly Drilling efficiency is reduced, bore size precision is most preferably only capable of control in 0.2.It is less than 5mm to diameter, depth is more than 100mm's Aperture performance difficulty, as diameter is smaller, depth reaches 500 or even 1000 aperture, or workpiece hardness higher than HB320, machinability The material of energy difference, commonsense method can not process at all.

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 endoporus accuracy and finish of drilling.Meanwhile during gun drilling, the working environment of drill bit is relatively closed and narrow, its Radiating and chip removal are more difficult, and it is cold that existing drill bit designs on drill bit hollow lubrication in order to solve the above problems, often But 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 Amplitude increase in high-speed motion, further reduce the linearity of deep hole drilling cuttings.

Therefore, be badly in need of it is a kind of work continuously, be high in machining efficiency, endoporus accuracy and highly polished lathe, complete to small The processing of deep hole, high-precision tube.
