Description
Technical field
The utility model relates to a kind of numerical control gun drill, refers in particular to a kind of numerical control high-effective deep hole gun drill.
Background technology
At present, it is very general to run into the aperture of boring situation more and more littler, that boring is more and more grown in the machinery manufacturing industry.Therefore, the deep hole machining technology has obtained using widely.As the mold runner in the die industry, thimble boring; The boring of steering box input (going out) axle, tooth bar, gearbox, gear shaft in the auto parts and components, the boring on the bent axle in the engine, connecting rod, camshaft, cylinder body, cylinder cap, the piston; Deep hole machining in instrument, electric power, the petrochemical industry, or the like.Yet the restriction that common driller (machine) is subjected to himself 26S Proteasome Structure and Function can not realize deep hole machining.
There are following four major defects in existing commercially available numerical control gun drill: the one, adopt the hydraulic means holding workpiece, and adjust quite inconvenience of clip position according to Workpiece length; The 2nd, front-end driven stepper motor and tooth bar installation site are improper, cause the lathe volume quite huge, have improved the lathe manufacturing cost; The 3rd, cutting fluid can not recycle immediately, usually needs to change machining integrated cost height; The 4th, when cutter is in overload because of blocking, often damage cutter, damage complete machine when serious.
A major obstacle that reduces gun drill machining integrated cost is that the consumption of cutting fluid (playing cooling, lubrication) can not reduce effectively, and the expense of changing cutting fluid accounts for the 25%-28% of total processing cost usually.Huge in view of the cutting fluid use amount, improve the economic benefit that has its service life clearly.
Gun drill is in machining, and the microcosmic stressing conditions of cutter is unknowable.When cutter is in overload because of blocking, if untimely parking or cutter withdrawed from, very easily causes tool damage or fracture.Particularly in the deep processing cutting, because the cutting process is not visible, this type of fault very easily takes place.
Chinese patent once disclosed a kind of " inverted gun drill structure " (TaiWan, China, notification number 201175777Y, January 7 2009 day for announcing), mainly be to comprise by a material folding unit and a drill bit unit being formed, wherein: the frame of described material folding unit is vertically to be built up on the pedestal (or floor), and be provided with a chuck assembly on the frame top, described chuck assembly is provided with the chuck that drives rotation by means of motor in its side, and can rely on the orientation and the angle of slew gear change chuck wherein; Described drill bit unit is provided in a side of material folding unit one side and but oscilaltion is moved, and its drill bit is to be provided with from bottom to top and not rotate for fixing; When using according to above-mentioned structure, chuck must move to corresponding to directly over the drill bit and rotation at a high speed, and the rise that relies on drill bit again to be reaching the boring function, and helps when boring and discharging drilling cuttings, and can reduce the situation that the drill bit fracture takes place.It is with processed object and drill bit turned upside down, makes to add the drilling cuttings in man-hour in boring and fall down in can be easily by the hole.It does not overcome above-mentioned four major defects, can not accomplish deep hole machining.
