Embodiment
The embodiment of technical solutions of the utility model is described in detail below in conjunction with accompanying drawing.Following examples are only For clearly illustrating the technical solution of the utility model, therefore example is only used as, and this practicality can not be limited with this New protection domain.
As shown in Figure 1-2, the main shaft nose that the embodiment of the utility model one is provided holds system 1 tightly, including:Main shaft protecgulum 11 and piston 12;Main shaft protecgulum 11 has piston hole 111, and the inner of wherein piston hole 111 extends to the inner ring of main shaft protecgulum 11 Face, the outer end of piston hole 111 are used to be connected with high-pressure fluid;When main shaft protecgulum 11 is fixed on into the nose of main shaft 2 and to piston When high-pressure fluid is injected in hole 111, piston 12 can be stretched out in main shaft protecgulum 11 along its inner that is axially slided to of piston hole 111 Anchor ring is simultaneously pressed on the mandrel 21 of main shaft 2.
Main shaft nose provided by the utility model holds the nose that system 1 is used for the main shaft 2 installed in numerical control machining center tightly End, part is processed using the numerical control machining center for being provided with high pressure holding system, when needing milling, directly in main shaft 2 installation milling cutters can be implemented to part milling;When needing turning, turning cutting tool is installed on main shaft 2, and to piston hole 111 injection high-pressure fluids, so that the inner ring surface that is axially slided to its inner stretches out main shaft protecgulum 11 of the piston 12 along piston hole 111 And be pressed on the mandrel 21 of main shaft 2, i.e., now the relative main 2 of mandrel 21 is fixed, so that turning cutting tool has enough rigidity Turning is implemented to part with support, and reaches expected turning effect.
In order to further improve compression degree of the piston 12 to the mandrel 21 of main shaft 2, piston in the utility model embodiment 12 inner end face is the cylindrical adaptable arcuation with mandrel 21, consequently, it is possible to which the inner face of piston 12 is in bag to mandrel 21 The gesture of network, adds the contact surface of the two, namely adds the frictional force for hindering mandrel 21 to rotate, and has reached so-called compression mandrel 21 purpose.
After terminating to accessory turning, it usually needs resetted piston 12, so as to the progress of follow-up milling process.Base In this consideration, the utility model embodiment also includes return springs;One end of return springs is connected with main shaft protecgulum 11, separately One end is connected with piston 12;When stopping injecting high-pressure fluid to piston hole 111, piston 12 can be in the effect of return springs It is lower to be separated along its inner that is axially slided to of piston hole 111 with mandrel 21.Specifically elastic component can select spring, flexure strip etc. Flexible device,
Further, the utility model embodiment also includes:Positioning screw 13;Main shaft protecgulum 11 also has positioning screw hole 112, positioning screw hole 112 and the coaxial communication of piston hole 111, and the diameter of positioning screw hole 112 is not less than the diameter of piston hole 111; Positioning screw 13 is screwed in positioning screw hole 112.The purpose for setting bolt-hole essentially consists in the installation for facilitating piston 12 or torn open Unload, when needing to dismantle piston 12, first disassemble positioning screw 13, then piston 12 is passed through positioning screw hole by can 112 take out.
If piston 12 is inner to occur rotation when compressing mandrel 21, it is likely to damage the surface of mandrel 21, is Avoid the generation of the problem, the piston 12 opposing pistons hole 111 in the utility model embodiment is circumferentially fixed.In order to realize work Plug 12 it is circumferentially fixed, can be specifically non-revolved body by the Cross section Design of piston 12, for example the section of piston hole 111 is oval Shape;At least part section of piston 12 is the ellipse being adapted with the section of piston hole 111.
In order to which more firm obstruction mandrel 21 rotates, the quantity of piston hole 111 is multiple in the utility model embodiment, and Multiple piston holes 111 are arranged at the diverse location of main shaft protecgulum 11, one piston 12 of corresponding assembling in each piston hole 111.I.e. Multiple thrusts can be applied to mandrel 21 simultaneously, especially multiple piston holes 111 are using the axis of main shaft protecgulum 11 as axis isogonism Spend annular array best results.
Preferably, being radially arranged along main shaft protecgulum 11 of piston hole 111.Consequently, it is possible to high-pressure fluid applies to piston 12 Axial force can be completely used for being applied on mandrel 21, improve the utilization rate of high-pressure fluid exerted forces.
