The automatic aligning clamp mechanism of scroll chuck of the present utility model is further set to: described floating holding jaw seat, floating holding jaw body are equipped with 3.
The automatic aligning clamp mechanism of scroll chuck of the present utility model is further set to: each floating holding jaw body is provided with a pair of jaw, and this is installed on floating holding jaw body by a pair of soket head cap screw jaw.
The automatic aligning clamp mechanism of scroll chuck of the present utility model is further set to: described fixed head is arranged on the top of this floating holding jaw seat by some dog screws.
The automatic aligning clamp mechanism of scroll chuck of the present utility model is also set to: on each floating holding jaw body, butt has two Compress Springs.
Compared with prior art, the utlity model has following beneficial effect:
1. the chucking power of the automatic aligning clamp mechanism of scroll chuck of the present utility model is even, and in clamping, the spring automatic adjusting position of floating holding jaw body left and right, guarantees the center of product and the center superposition of chuck.
2. the floating holding jaw body of the automatic aligning clamp mechanism of scroll chuck of the present utility model is done radial floating clamping according to the external diameter of product, can thin, long, the irregular product of clamping wall.
Accompanying drawing explanation
Fig. 1 is the three-dimensional exploded view of the automatic aligning clamp mechanism of scroll chuck of the present utility model.
The specific embodiment
Refer to shown in Figure of description 1, the utility model is a kind of automatic aligning clamp mechanism of scroll chuck, and it is assembled by several parts such as three-jaw high speed hollow Oil-pressure clamping head 1, floating holding jaw seat 2, fixed head 3, floating holding jaw body 4, Compress Spring 5, pull bar 6 and middle real angling cylinders 16.
Wherein, the three-jaw high speed hollow Oil-pressure clamping head 1 that described three-jaw high speed hollow Oil-pressure clamping head 1 is prior art, does not repeat them here.
Described floating holding jaw seat 2 is fixed on a side of pawl high speed hollow Oil-pressure clamping head 1, and it is specifically provided with 3.Described fixed head 3 is arranged on the top of this floating holding jaw seat 2 by some dog screws 18, be bolted with a pair of adjustment screw 7 on it.
Be fixed with a fixed axis 8 in a side of described floating holding jaw seat 2, this fixed axis 8 is provided with a needle bearing 9, and described floating holding jaw body 4 is articulated on needle bearing 9, thereby makes the floating holding jaw body 4 can be around fixed axis 8 pivotables.On fixed axis 8, be also provided with packing ring 10 and hexagon thin nut 11, this packing ring 10 is connected to the outside of floating holding jaw body 4.
Described floating holding jaw body 4 is also provided with 3, and each floating holding jaw body 4 is provided with a pair of jaw 12, and this is installed on floating holding jaw body 4 by a pair of soket head cap screw 13 jaw 12.
One end of described Compress Spring 5 is accommodated and is connected on floating holding jaw body 4, and other end butt is to adjustment screw 7.And butt has two Compress Springs 5 on each floating holding jaw body 4.
Described pull bar 6 one end are connected on three-jaw high speed hollow Oil-pressure clamping head 1 by an attaching nut 14, and the other end is connected with middle real angling cylinder 16 by a locking nut 15.Central real angling cylinder 16 is by pull bar 6 toward post-tensioning, and three-jaw high speed hollow Oil-pressure clamping head 1 converts axial tension to by its inner tapered wedge surface the radially chucking power at jaw 12Xiang center; Contrary, pull bar 6 pushes away forward, and in three-jaw high speed, the jaw 12 on Null oil-pressure folder 1 does radially releasing orientation towards periphery.
The design principle of the automatic aligning clamp mechanism of scroll chuck of the present utility model is as follows: three-jaw high speed hollow Oil-pressure clamping head 1, in the process clamping, drives the each part on floating holding jaw seat 2 to draw close to center.The moment that jaw 12 and workpiece 17 are touched, according to the outer surface of workpiece 17, floating holding jaw body 4 is a unsteady angle around fixed axis 8 left and right, just completes subsequently self-centering, and the action of clamping work pieces 17.Then tighten dog screw 18, when preventing three-jaw high speed hollow Oil-pressure clamping head 1 High Rotation Speed, floating holding jaw body 4 rotates around fixed axis 8, after workpiece 17 is machined, unclamps dog screw 18, and Compress Spring 5 makes floating holding jaw body 4 be reset to nature.
The above specific embodiment is only the preferred embodiment of this creation, not in order to limit this creation, any modification of making, is equal to replacement, improvement etc., within all should being included in the protection domain of this creation within all spirit in this creation and principle.
