Description
Technical field
The utility model relates to a kind of hydraulic pressure handle of a knife.
Background technology
In handle of a knife system, handle of a knife adopts spring housing cartridge type, hot charging formula, side-strengthened, conical surface needle roller compression type etc. conventionally to the clamping of the cutters such as drilling, milling.Several modes are mostly and rigidly fix above, when cutter in use produces vibrations, can cause certain damage to cutter.And existing a kind of hydraulic pressure handle of a knife employing is flexible fixing, as the application number disclosed a kind of hydraulic cutter tension device for circle shear of Chinese patent that is 201120346104.X, comprise resilient sleeve, hydraulic pressure chamber and the hydraulic bolt etc. with elasticity hole wall, during use, cutter is packed in resilient sleeve, cutter periphery is corresponding with elasticity hole wall, screw hydraulic bolt, can make the fluid pressure in hydraulic pressure chamber increase, elasticity hole wall produces distortion under the effect of hydraulic pressure, tool-holder is fastened, complete holding action.But, adopting hydraulic pressure handle of a knife of the prior art is to rely on sleeve lining face to realize to the clamping of cutter, clamping force is little, size and Geometrical Tolerance Principle to elasticity hole wall are higher, and the deformation of the axial both sides of elasticity hole wall and mid portion is inconsistent, during clamping will there is bigger difference to the chucking power of cutter periphery in the various piece of elasticity hole wall, therefore can exert an influence to the balance of cutter, and then affect the machining accuracy of workpiece.Particularly for the processing of deep hole, because the cutter length that overhangs is longer, the problems referred to above will be more obvious.
Utility model content
The purpose of this utility model is to provide a kind of hydraulic pressure handle of a knife of chucking power high conformity of elasticity hole wall tool setting tool periphery.
The technical solution adopted in the utility model is: a kind of hydraulic pressure handle of a knife, comprise the resilient sleeve with hydraulic pressure chamber and elasticity hole wall, on described elasticity hole wall, along the axially spaced-apart of resilient sleeve, be provided with many groups for holding out against the clamping projection of periphery of cutter, clamping projection in each group is all along perpendicular to axial direction being circumferentially evenly equipped with more than three, or the clamping projection in each group has angle along the perpendicular to axial direction line being circumferentially evenly equipped with between two clamping projections in line and the adjacent sets between two clamping projections in two and any a group, each described clamping projection has identical height of projection.
Described clamping projection is arc surface or sphere for pushing up friction tight surface with the periphery of cutter.
Described clamping projection is for being arranged on the steel ball on elasticity hole wall.
On resilient sleeve axial direction, the corresponding end of the clamping of outermost end projection and end elasticity hole wall has the distance of setting.
The front end of described resilient sleeve is the cutter insertion end of inserting for cutter, and the outer surface of described resilient sleeve is the conical surface that point diameter is little, rear end diameter is large.
A kind of hydraulic pressure handle of a knife of the utility model adopts technique scheme, owing to being provided with many groups for holding out against the clamping projection of periphery of cutter along resilient sleeve axially spaced-apart on hydraulic pressure handle of a knife elasticity hole wall, clamping projection in each group is all along perpendicular to axial direction being circumferentially evenly equipped with more than three, or the clamping projection in each group has angle along the perpendicular to axial direction line being circumferentially evenly equipped with between two clamping projections in line and the adjacent sets between two clamping projections in two and any a group, and each described clamping projection has identical height of projection, therefore during clamping cutter, the not periphery of immediate roof push type broach tool of the elasticity hole wall of hydraulic pressure handle of a knife, but rely on the clamping projection top push type broach tool that height of projection is equal, hydraulic clamping projection is that point contacts with the outer peripheral face of cutter, the impact of the machining accuracy that can avoid cutter periphery and elasticity hole wall on clamping force, chucking power is large, clamp high conformity.
Accompanying drawing explanation
Fig. 1: the structural representation of an embodiment of a kind of hydraulic pressure handle of a knife of the utility model.
The name that in figure, each Reference numeral is corresponding is called: 1 resilient sleeve, 2 hydraulic pressure chambers, 3 elasticity hole walls, 4 steel balls, 5 cutters.
The specific embodiment
An embodiment of a kind of hydraulic pressure handle of a knife of the utility model as shown in Figure 1, comprises resilient sleeve 1, and the front end of resilient sleeve 1 is the cutter insertion end of inserting for cutter 5.Described resilient sleeve 1 has hydraulic pressure chamber 2 and elasticity hole wall 3, hydraulic pressure chamber 2 adopts the principle identical with prior art middle hydraulic chamber 2, and along the axially spaced-apart of resilient sleeve 1, be provided with many groups for holding out against the steel ball 4 of periphery of cutter 5 on elasticity hole wall 3, steel ball 4 in each group is all along perpendicular to axial direction being circumferentially evenly equipped with more than three, and the diameter of each steel ball 4 is identical and have identical height of projection.Like this, steel ball 4 is formed for pushing up friction tight sphere with the periphery of cutter 5 on elasticity hole wall 3, during hydraulic pressure handle of a knife clamp-on tool 5, each steel ball 4 and cutter 5 peripheries are and contact, clamping force is large, the impact of the machining accuracy that can avoid cutter 5 peripheries and elasticity hole wall 3 on clamping force, chucking power high conformity.For the impact on chucking power of the deformation difference that reduces elasticity hole wall 3 axial edge parts and mid portion, on resilient sleeve 1 axial direction, the steel ball 4 of outermost end and the corresponding end of holding elasticity hole wall 3 have the distance of setting.
In addition, the outer surface of resilient sleeve 1 is the conical surface that point diameter is little, rear end diameter is large, can reduce the interference between handle of a knife and workpiece, thereby can use the shorter cutter of length 5, reduce the long impact on cutter 5 balances of cutter 5, be conducive to improve machining accuracy.
In the above-described embodiments, clamping projection in each group is all along perpendicular to axial direction being circumferentially evenly equipped with more than three, in other embodiments, clamping projection in each group also can have angle along the perpendicular to axial direction line being circumferentially evenly equipped with between two clamping projections in line and the adjacent sets between two clamping projections in two and any a group, can realize equally the clamping to cutter.In addition, in the above-described embodiments, what clamping projection adopted is steel ball 4, and on resilient sleeve 1 axial direction, the corresponding end of the steel ball 4 of outermost end and end elasticity hole wall 3 has the distance of setting, in other embodiment of the present utility model, clamping projection also can adopt other structures outside spheroid, and such as top is the projection of plane, sphere or non-spherical arc etc.; And clamping projection also can be always vertically spread configuration to the axial edge of elasticity hole wall 3.Moreover in other embodiments, the outer peripheral face of resilient sleeve 1 also can be arranged to cylinder.
