In figure: 1 is chuck handle, 14 is clamping seats, and 15 is worm gear, and 16 is rebound, and 19 is circular sleeve, and 22 is steel ball, and 29 is worm screw, and 30 is cubic group, and 31 for tripartite organizes chuck, and 32 is sealing plate, and 33 is tripartite's group
30-1 is projection, and 30-2 is quadrangle clamp, and 30-3 is square hole, and 33-1 is triangle clamp, and 33-2 is projection, and 33-3 is delthyrium
The specific embodiment
As shown in Figure 1, elastic yarn conial chuck of the present utility model comprises chuck handle 1, circular sleeve 19 and clamping seats 14.On described circular sleeve 19, have the cavity adapting with chuck handle 1, described circular sleeve 19 is sleeved on chuck handle 1 outside.For the torsion of chuck handle is passed to circular sleeve, described chuck handle 1 outside is provided with pit; It is logical that the position that described circular sleeve 19 sidewalls and pit adapt has strip, and the steel ball 22 of transmitting torque is set between described pit and groove.When lathe drives chuck handle 1 to rotate, steel ball 22 can be delivered to the torsion of chuck handle on circular sleeve 19 like this, thereby circular sleeve is rotated.Because the clamping seats 14 of elastic yarn conial chuck is used for clamping screw tap, need to drives screw tap to rotate by clamping seats 14 and realize feeding, so the torsion of circular sleeve 19 need to be passed to clamping seats 14.As shown in Figure 1, described circular sleeve 19 surroundings are provided with some steel balls, and described steel ball is connected with clamping seats 14 by the clutch of transmitting torque.
In described clamping seats 14, be provided with screw tap clamp mechanism, described screw tap clamp mechanism comprises and is arranged on worm gear 15 and the worm screw 29 of matching in clamping seats, and worm gear 15 and worm screw 29 gear pairs match.As shown in Figure 2, in the middle of described worm gear 15, have the cavity that holds four directions group 30, described cubic group comprises four quadrangle clamp 30-2 that are evenly distributed on cavity radial circumference, described quadrangle clamp is arranged the square hole 30-3 that is formed for clamping screw tap squared ends successively, and described square hole 30-3 is centered close on the axis of described chuck handle.For the rotation realizing by worm gear 15 realizes the object that zooms in or out square hole 30-3, on described quadrangle clamp, be fixed with cylindrical projection 30-1, in the other clamping seats of described worm gear, be provided with rebound 16, described rebound near a side of worm gear have with quadrangle clamp on the groove that adapts of cylindrical projection 30-1.The squared ends of screw tap is placed in square hole 30-3, by rotating screw bolt 29, worm gear 15 is rotated, be positioned at worm gear cavity due to cubic group, according to a direction, rotate and can drive cylindrical projection 30-1 to move in the groove of rebound, so just drive quadrangle clamp 30-2 to move along groove, thereby realize zooming in or out of square hole 30-3, also just can realize the clamping of screw tap and unclamp.Because the size of square hole is adjustable, elastic yarn conial chuck of the present utility model can adapt to the screw tap of multiple different size.
For further fixing screw tap, described screw tap clamp mechanism also comprises that the tripartite who is arranged on rebound opposite side organizes chuck 31, and described tripartite organizes and in chuck 31, is provided with tripartite and organizes 33.As shown in Figure 3, described tripartite organizes on the radial circumference of chuck 31 and is uniformly distributed three triangle clamp 33-1, described triangle clamp 33-1 arranges the delthyrium 33-3 that is formed for clamping screw tap post handle successively, described delthyrium is positioned on the axis of described chuck handle, can guarantee like this to adopt four directions group and tripartite to organize while clamping screw tap, screw tap can not tilt.On described triangle clamp, near a side of rebound, be fixed with cylindrical projection 30-2, the side that described rebound is organized chuck near tripartite also have with triangle clamp on the groove that adapts of cylindrical projection 30-2.Here tripartite organizes that to clamp the principle of screw tap identical with four directions group, and four directions group and tripartite organize and by the groove on rebound, realize the action of quadrangle clamp and triangle clamp, has so just guaranteed that cubic group and tripartite organize the synchronism of clamping screw tap.
Described tripartite organizes chuck 31 outsides and is fixed with removable seal plate 32, and described clamping seats inwall is provided with screw thread, and described sealing plate outer surface is provided with the screw thread matching with clamping seats inner thread.
