Detailed description of the invention
All features disclosed in this description, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Arbitrary feature disclosed in this description (comprising any accessory claim, summary and accompanying drawing), unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in detail.
As shown in Figures 1 to 10, Fig. 1 to Figure 10 shows section components structural representation in the utility model embodiment.The present embodiment hydraulic cylinder self-centering inner support clamp, the double end screw mandrel 1 that its structure comprises positioning tube 2 and is transverse in described positioning tube, double end screw mandrel one end connects rotary power unit, other end attaching nut 9.Concrete, rotary power unit can be motor or motor, and preferably, in the present embodiment, rotary power unit is air motor; The rotation of double end screw mandrel is driven by air motor.Air motor is connected with mounting disc, and mounting disc is used for the installation to fixture.
Positioning tube is provided with the opening for arranging inner bracing strip 6 and two unit heads; Concrete, opening is provided with three, can arrange three inner bracing strips 6.The sidewall of opening is provided with spigot surface; The end of positioning tube is provided with setting circle, and in the present embodiment, the major function of positioning tube is the skeleton of support fixture, bears the reaction force supporting workpiece, ensures fixture intensity, rigidity.When inner bracing strip struts workpiece, reaction force passes to unit head through inner bracing strip, and unit head cylindrical coordinates with the setting circle of positioning tube, thus is born the reaction force supporting workpiece by positioning tube.Further, positioning tube end is also provided with limiting component, concrete, limiting component be angular contact bearing 7 and with angular contact bearing 8 with the use of axle bumper 8, positioning tube, simultaneously to the axial limiting of inner bracing strip, ensures that inner bracing strip is only to radial motion, thus at radial support workpiece.
The present embodiment medium power headgear is connected on double end screw mandrel; Unit head is driven to rotate by double end screw mandrel.Described inner bracing strip is arranged between described two unit heads.Two unit heads are left-handed unit head 4 and dextrorotation unit head 5.In order to assemble needs, unit head comprises unit head pawl 3, three unit head pawls and a unit head alignment pin is assembled, assemble aft-loaded airfoil brace table sliding surface after preliminary working, and preferably, inner bracing strip sliding surface is U-shaped structure.
Concrete, the present embodiment medium power head mainly transmits the power that air motor is passed to, unit head is arranged in pairs, double end screw mandrel drive under, positioning tube spacing under (both direction), two unit head centerings move axially (axial rotation can not occur), under the condition that two unit head centerings move axially, rely on the inner bracing strip sliding surface on unit head, inner bracing strip is moved on the inner bracing strip sliding surface of unit head, props up workpiece in radial direction.Inner bracing strip is positioned on the inner bracing strip sliding surface of unit head by the chute dog screw on unit head, inner bracing strip has the sliding tray of dog screw, and sliding tray is parallel with inner bracing strip sliding surface.
Further, inner bracing strip is three pieces, and described three pieces of inner bracing strips are distributed in described positioning tube.Each inner bracing strip comprises sliding surface 61, sliding surface 61 is provided with chute 62.In the present embodiment, inner bracing strip relies on the inner bracing strip sliding surface location of unit head, and under double end screw mandrel drives, two unit head centerings move axially, and inner bracing strip centering is large to radial direction support, relies on chute dog screw to be fallen in radial direction by inner bracing strip when falling after rise.
Preferred embodiment is, the inner bracing strip back side is provided with the inner bracing strip installing hole for increasing inner bracing strip.If inner bracing strip inner support diameter does not meet the demands, also inner bracing strip can be added at the inner bracing strip back side.
Concrete, the operation principle of the present embodiment is, air motor rotates, double end screw mandrel is driven to rotate, two unit heads rely on left and right to be threaded on double end screw mandrel, therefore two unit head synchronous centerings move, unit head spigot surface, locating surface coordinate with positioning tube, the inner bracing strip sliding surface of unit head coordinates with inner bracing strip, when unit head centering is moved, rely on inclined-plane to be strutted to radial direction by inner bracing strip, strut in process, unit head, inner bracing strip also have dog screw to lead in chute, and the screw mounting hole on positioning tube uses when rigging screw.The inner support clamp of the present embodiment can support diameter and change 50 millimeters (internal diameter 80-130 millimeters).As endoporus is larger, effect can be better.
Spoken of in this manual " embodiment ", " another embodiment ", " embodiment ", etc., refer to the specific features, structure or the feature that describe in conjunction with this embodiment and be included at least one embodiment of the application's generality description.Multiple place occurs that statement of the same race is not necessarily refer to same embodiment in the description.Furthermore, when describing specific features, structure or a feature in conjunction with any one embodiment, what advocate is also drop in scope of the present utility model to realize this feature, structure or feature in conjunction with other embodiments.
Although the multiple explanatory embodiment here with reference to utility model is described the utility model, but, should be appreciated that, those skilled in the art can design a lot of other amendment and embodiment, these amendments and embodiment will drop within spirit disclosed in the present application and spirit.More particularly, in the scope of, accompanying drawing open in the application and claim, multiple modification and improvement can be carried out to the building block of subject combination layout and/or layout.Except the modification of carrying out building block and/or layout is with except improvement, to those skilled in the art, other purposes also will be obvious.
