Description

Deep hole drilling auxiliary device

Technical field

The utility model relates to technical fields of mechanical processing, more particularly to a kind of deep hole drilling auxiliary device.

Background technique

Deep hole machining is an important branch of field of machining, is widely used in aerospace industry, national defense industry, stone Oily exploitation, rock drilling, lathe, automobile and other industries.Gun drilling has very big difference compared with turning, milling etc., in depth drill During cutting, bit cutting condition is very severe, and the discharge of the generation sum of chip is completed in narrow hemi-closure space, Phenomena such as bit wear is fast, is easy to produce tipping, breakage and stifled bits, especially in the drilling process of ultralong deep hole, due to knife bar It is long, intensity is low, poor rigidity, easily there is bit deflection and the problems such as processing hole can't meet the quality requirement.Therefore, deep hole machining one It is directly a problem of field of machining.

Currently, mainly facing following difficulty when carrying out deep hole drilling to stainless steel long axis using drilling machine:

(1) material property of processing object: firstly, for the preferable stainless steel of antiseptic property (such as 316 stainless steels), Its metallographic structure is mostly martensite, processing hardening is easily formed in process, to cause being seriously worn for process tool. Secondly, stainless steel hot intensity is high, and temperature is higher, and required cutting force is also bigger, and the power of consumption is also more, is formed pernicious Circulation.Furthermore stainless steel plasticity is very good, and when drilling easily forms built-up edge, drastically reduces cutter life, and especially 316 The thermal coefficient of stainless steel is very low, and the heat for causing drilling to generate is difficult to spread out of, and is further degrading drilling environment.Separately Outside, 316 stainless steel wire coefficients of expansion 45# steel more common than drilling machine spiral bit is big, will appear aperture ratio drill bit ruler after the cooling period Very little small situation, this can generate serious consequence in deep hole drilling.

(2) deep hole drilling process: firstly, with the continuous intensification of drilling in drilling process, drill bit has with hole wall Longer contact and friction, friction and drill thrust generate great cutting heat, constantly deteriorate drilling environment.Secondly, deep hole machining When, chip removal is extremely difficult, in hole or is filled with acinous chip always or is wrapped spiral shape chip always, to brill The abrasion of head is very big.In addition, drill bit is elongated, intensity is low, poor rigidity, is easy to produce deformation and vibration when deep hole processing, cause to bore Head and fractures at tipping.

It can be seen that being that how to radiate using the key problem that drilling machine carries out deep hole drilling to stainless steel long axis Cooling and lubrication chip removal.

Cutting fluid is a kind of in the cutting such as metal, glass, polishing process, for cooling down and lubricating cutter and processing Liquid is commonly used in the industry of part, is provided simultaneously with good cooling performance, greasy property, rustless property, oil removing cleaning function, anti-corrosion function Energy, easily dilutable feature.Addition using cutting fluid be current deep hole drilling cuttings carry out it is cooling, promote chip removal common technology means, still, Cutting fluid usage mode is mostly to spray to cutting operation position, faces gun drilling, cutting fluid is difficult to be sent to cutting region, existing Improvement also tends to be that increasingly complex cutting fluid spray assemblies are arranged for lathe；And the cutting fluid sprayed out can flow to machine Table face, influences working environment.
