Detailed description of the invention
Below in conjunction with accompanying drawing, principle of the present invention and feature are described, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figures 1 to 3, described a kind of axial location turning attachment that do not stop, be characterized in comprising main casing 1, main casing 1 outside is connected with right shell body 7 by adapter sleeve 6, thrust bearing 3 is arranged on main casing 1, and on right shell body 7, corresponding thrust bearing 3 is provided with spring born work arbor 5, the second back-moving spring 4 one end and is set on spring born work arbor 5, second back-moving spring 4 other ends contact with thrust bearing 3, and on right shell body 7, corresponding spring born work arbor 5 is also provided with and adjusts screw 9; Between main casing 1 and right shell body 7, sliding sleeve 8 is set, described main casing 1 left end is set to the Morse's taper structure being connected with lathe mohs tapered bore, main casing 1 right-hand member is set to the fixing clutch tapered configuration of the transmission main shaft cutting moment corresponding with activity clutch seat 10, activity clutch seat 10 is arranged on backstay 17, between backstay 17 inner faces and main casing 1, be provided with the first back-moving spring 2, on activity clutch seat 10, inner sleeve 14 is installed, in inner sleeve 14, be provided with tapered sleeve 13, in the centre bore of tapered sleeve 13, be installed with collet 16 by junction of the edges of two sheets of paper screw 15.
Further, between described activity clutch seat 10 and inner sleeve 14, be provided with spring leaf 11, spring leaf 11 is fixedly mounted on inner sleeve 14 inner faces by trip bolt 12.
Further, described spring born work arbor 5 and the second back-moving spring 4 are along being evenly set to three groups on right shell body 7 circumference.
Further, described backstay 17 is connected by spline with activity clutch seat 10, backstay 17 the inners stretch into main casing 1 and with main casing 1 and the concentric setting of right shell body 7, backstay 17 outer ends and the top corresponding workpiece axial location that realizes of tailstock tool, spline on backstay 17 is realized backstay 17 and is slid axially, and described collet 16 is realized workpiece radial centering clamping.
Further, described tapered sleeve 13 the inners are provided with the stepped hole contacting with inner sleeve 14 with activity clutch seat 10 respectively, and the conical surface of tapered sleeve 13 peripheries and right shell body 7 inner chambers are equipped with, and described collet 16 inner faces hold out against backstay 17.
Described a kind of axial location turning attachment that do not stop, dead ship condition is not: the left end of main casing 1 inserts in machine tool chief axis mohs tapered bore and rotates with main shaft, be connected with right shell body 7 by adapter sleeve 6, sliding sleeve 8, right shell body 7, tapered sleeve 13, collet 16 float, activity clutch seat 10 disengages with main casing 1 fixing clutch seat position, in quick condition.Workpiece adds man-hour, and workpiece left end cylindrical is inserted in collet 16 taper holes, and workpiece right-hand member moves to left under the top promotion of tailstock tool, through inner sleeve 14, tapered sleeve 13, promotion right shell body 7 compresses the second back-moving spring 4 and together moves to left, and in the time that adapter sleeve 6 and main casing 1 disengage, stops floating.Tailstock centre promotes workpiece to be continued to move to left, until its end face is secured on backstay 17 right sides, realizes axial location.Meanwhile, collet 16 is by excircle of workpiece clamping, and activity clutch seat 10 contacts with main casing 1 right-hand member, starts to transmit cutting moment.Due to the elastic reaction of the second back-moving spring 4 and spring leaf 11, workpiece outside dimension tolerance and alignment error are converted into right shell body 7 and the axial stroke of collet 16 is compensated.After completion of processing, unclamp tailstock centre, the second back-moving spring 4 promotes right shell body 7, tapered sleeve 13, activity clutch seat 10 and inner sleeve 14, the first back-moving springs 2 to the right and promotes backstay 17 and reset, and workpiece end face pushed away from collet 16, can unload safely workpiece.
Described a kind of axial location turning attachment that do not stop, when use, can estimate clamping force according to factors such as workpiece external diameter and weight, selects collet specification.In assembling and setting, should ensure meet certain clamping force and backstay adjustment apart from time, the tight joint between activity clutch seat 10, main casing 1 right-hand member, makes to cut moment and meets the demands.The first back-moving spring 2, the second back-moving spring 4, spring leaf 11 should ensure after tailstock centre unclamps, and activity clutch seat 10 can disengage with main casing corresponding site, and workpiece end pushed away from collet 16.Described a kind of axial location turning attachment that do not stop, in assembling and setting process first, for making to form and cut moment between collet 16 and activity clutch seat 10, if desired, can be by changing the first back-moving spring 2 and second back-moving spring 4 of different-stiffness, or increase and adjust pad at spring leaf 11 places, with compensate for clearance.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
