Description
Technical field
The utility model relates to the leakage-proof structure of main shaft of numerical control machine tool, specifically a kind of leakage-proof structure of spindle taper hole central water outlet.
Background technology
In Digit Control Machine Tool field, metalworking fluid (i.e. cooling fluid) use in metal cutting process is the type of cooling main in metal cutting process.Metalworking fluid plays cooling, lubrication, cleaning and the important function such as antirust to cutter and processing parts.
Usually have two kinds with metalworking fluid to the mode that cutter cools: one makes cutter cool outward, another kind is named cutter inner cooling but.It is that lathe is when doing machining that cutter cools outward, in order to ensure crudy, effects such as metalworking fluid being placed in the outside of cutter and work pieces process part, with high pressure by metalworking fluid splash to the point of a knife and workpiece of cutter, cooling, lubrication being played to cutter and workpiece, clean and be antirust.But cool outward for cutter, in process, due to the impact of the centrifugal force of the cutter by High Rotation Speed, most of cutting fluid is thrown out of, and cooling effect is not good; In addition, when carrying out deep hole machining, being difficult to enter the factors such as machining area by cooling fluid affects, and cooling effect can be caused equally not good.And although cutter inner cooling cooling effect is relatively better, but also there is certain deficiency: existing leak free design is only installed a pull bar envelope and carried out leakproof on broaching tool bar, lathe is when carrying out deep hole machining, the cutting fluid flowed into through the centre bore of broaching tool bar enters tapered sleeve and taper hole, larger impulsive force can be produced to the pull bar envelope on broaching tool bar, and broaching tool bar uses frequent, pull bar envelope on it is not long for service life, yielding, damage, thus cause cooling fluid to be leaked and flow in lathe, mix with lubricating oil, very big damage is caused to lathe, and the phenomenon of leakage of this cooling fluid is often difficult to find, once find also late.
Summary of the invention
Technical problem to be solved in the utility model is: for the deficiencies in the prior art, provides that a kind of structure is simple, the leakage-proof structure of good leak-proof effect, long service life spindle taper hole central water outlet.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of leakage-proof structure of spindle taper hole central water outlet, comprise and be arranged on first order sealing mechanism outside broaching tool bar and second level sealing mechanism, described first order sealing mechanism is near the front end of main shaft, the guiding gutter of annular is provided with between described first order sealing mechanism and described second level sealing mechanism, described guiding gutter is opened on the perisporium of tapered sleeve, described tapered sleeve is set on described broaching tool bar, described tapered sleeve is arranged in the taper hole of described main shaft, described guiding gutter is connected with a rhone.
First order sealing mechanism and second level sealing mechanism form double-layer sealing structure, after installing and using, centre bore through broaching tool bar flows into the cutting fluid of tapered sleeve and taper hole once flow backwards, after pressure effect breaks through first order sealing mechanism, to flow in guiding gutter, then discharge through rhone, and lathe inside can not be entered.Why can not enter lathe inside, because guiding gutter and rhone form the space of an opening, guide functions is risen to the cooling fluid flow backwards, surge can not be produced to second level sealing mechanism, while playing good leak preventing effect, service life and the sealing effectiveness of second level sealing mechanism can be guaranteed, thus significantly reduce the possibility of lathe water inlet.
Described first order sealing mechanism comprises an O type circle and the first pull bar envelope, and a described O type circle is arranged between described main shaft and described tapered sleeve, and the first described pull bar envelope is arranged between described tapered sleeve and described broaching tool bar; Described second level sealing mechanism comprises the 2nd O type circle and the second pull bar envelope, and the 2nd described O type circle is arranged between described main shaft and described tapered sleeve, and the second described pull bar envelope is arranged between described tapered sleeve and described broaching tool bar; A described O type circle and described first pull bar envelope and the 2nd described O type circle and the second described pull bar envelope lay respectively at the both sides of described guiding gutter.O type circle seals with pull bar the design coordinated, and structure is simple, is convenient to install, good sealing effect.
Described rhone comprises the first row tank and second row tank that are connected, described first row tank is opened on described main shaft, described guiding gutter is connected with described first row tank, described second row tank is opened in the flange wall of described tapered sleeve, the flange wall of described tapered sleeve and the front end surface junction of described main shaft are provided with the 3rd O type circle, and the 3rd described O type circle is arranged on the outside of described second row tank.Machine cut adds man-hour, and tapered sleeve is with main shaft High Rotation Speed, and the cooling fluid of refluence finally flows out through second row tank and is thrown out of lathe.
Compared with prior art, the utility model has the advantage of: the leakage-proof structure of spindle taper hole central water outlet disclosed in the utility model, its first order sealing mechanism and second level sealing mechanism form double-layer sealing structure, after installing and using, centre bore through broaching tool bar flows into the cutting fluid of tapered sleeve and taper hole once flow backwards, and after pressure effect breaks through first order sealing mechanism, will flow in guiding gutter, then flow out through rhone, and lathe inside can not be entered.The utility model structure is simple, good leak-proof effect, long service life.
