Beneficial effect of the present invention: by the operation principle of lever principle and swell fixture, power pull bar is acted on a pulling force vertically all the time, elastic expansion is overlapped be in swelling state all the time between outer flare nut, and then elastic expansion cover is stretched on heart carrier for bolt, thus eliminate heart carrier for bolt gap, avoid chatter mark to produce, this structure is on the original rigid foundation of maintenance, improve centering precision, shorten manufacturing procedure, reduce manufacturing cost.
In addition, with two centre bores for positioning datum, improve gear hobbing with post degree; By lever and lathe self hydraulic system Synchronization Control, facilitate the clamping of workpiece, improve operating efficiency.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is use structural representation of the present invention.
Detailed description of the invention
The present invention is further described below in conjunction with specific embodiment and accompanying drawing.
A kind of chain digital control gear hobbing machine grasping system as shown in Figure 1, comprise machine tool chief axis 1, coaxial line is fixedly arranged on top 2 on this machine tool chief axis 1, and be arranged on this machine tool chief axis 1 and have and the described top heart carrier for bolt 3 be coaxially set, described heart carrier for bolt 3 overlaps 8 stationary positioned by the elastic expansion be connected on machine tool chief axis 1, and the expanding end of elastic expansion cover 8 and heart carrier for bolt 3 location fit are arranged, this elastic expansion cover 8 is provided with outer flare nut 9; Establish lever 7 described machine tool chief axis 1 end is hinged; In this machine tool chief axis 1 inside, power pull bar 6 is set along axis hollow hinged with described lever 7, wherein, and the hinged outer flare nut 9 of lever, between power pull bar 6 and lever 7, forms lever transmission mechanism.
Elastic expansion cover 8 in the present invention and the structural relation between outer flare nut 9, the use principle of similar " swell fixture " of the prior art, the expanding end being overlapped 8 by the male cone (strobilus masculinus) of outer flare nut 9 and elastic expansion forms an extrusion expansion structure, make elastic expansion overlap 8 and heart carrier for bolt 3 between be in tensioning state all the time, thus eliminate heart carrier for bolt gap, avoid the generation of chatter mark.And the tensioning state all the time between elastic expansion cover 8 and outer flare nut 9 is lever transmission mechanism, this lever transmission mechanism by lever 7 with the pin joint between itself and machine tool chief axis 1 for fulcrum, outer flare nut 9, between power pull bar 6 and lever, form lever transmission mechanism.As long as when power pull bar 6 having all the time a pulling force, elastic expansion can be made to overlap between 8 and heart carrier for bolt 3 and to be in tensioning state all the time.
For elastic expansion cover 8, its expanding end is provided with several sealing along its generatrix direction, as in this legend, the expanding end of elastic expansion cover 8 is provided with four sealings along its generatrix direction, time mainly in order to flare nut 9 tensioning outside, this expanding end expands tensioning, and this sealing is as buffering.And described outer flare nut 9 comprises the outer cone section that the expanding end overlapping 8 with elastic expansion forms extension relationship, and connect this outer cone section and the hinged lower link bar section of lever 7.
As the pulling force that power pull bar 6 applies, preferably, this power pull bar 6 is connected with machine tool oil pressure pull bar 5, that is to say itself and lathe self hydraulic system Synchronization Control, like this, facilitate the clamping of workpiece 11, and reduce the clamping workpiece time, improve operating efficiency.
