Abstract
The utility model provides a from tight mechanism in centering top, it includes box, centering piece, interior dagger, spring stop, compression spring, rotor arm, set up two bosss about centering piece one end, on one side the other end is equipped with a chamfer, two centering piece chamfer one end contact and arrange the box center in, and two centering piece chamfer contacts department form a cavity with the box, and the spring stop is fixed on box both sides limit. Compression spring places the cavity that boss, box and spring -catche hoarding become in, and interior dagger threaded connection is on the box, and the conical structure of internal stay pre -column end places the meet cavity of department of two centering pieces in, and the rotor arm is connected with interior dagger is perpendicular. Its simple structure, easy maintenance, the expense of saving, fault rate are hanged down, internal stay power can manual control.
Description
Technical field
This utility model relates to the mechanism holding out against the centering of the part that be there is a need to symmetrical self-centering location, particularly to a kind of manual self-centering jacking mechanism.
Background technology
At present, self-centering part great majority need to be realized by internal stay and use driven by power or the automatic inner-support structure of oil pressure actuated.But automatic inner-support structure generally exists, and structure is complicated, expense is high, fault rate is high, interior support force is excessive causes the shortcomings such as part deformation.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide the self-centering jacking mechanism of a kind of simple in construction, solves that the structure that existing automatic inner-support structure exists is complicated, expense is high, fault rate is high, interior support force is excessive causes the shortcomings such as part deformation.
In order to solve the problems referred to above, the technical solution of the utility model is,
A kind of self-centering jacking mechanism, it includes casing, center bridge, interior dagger, spring stop, compression spring, cursor；Arranging two boss about center bridge one end, the other end is provided with a chamfering, and two center bridge chamfering one end contact and are placed in casing center, forms a chamber with casing at two center bridge chamfer contact, and spring stop is fixed on casing dual-side.Compression spring is placed in the cavity that boss, casing and spring stop surround, and internal stay male screw is connected on casing, and interior dagger nose circle pyramidal structure is placed in the chamber of two center bridge joints, and cursor is vertical with interior dagger to be connected.
Further, center bridge boss is provided with locating dowel, and compression spring is enclosed within locating dowel.
Further, the cavity that boss, casing and spring stop surround is provided with two location springs.
During use, center bridge, compression spring being placed in casing, be fixed on casing by spring stop with screw, interior dagger is screwed on casing, and cursor is set on interior dagger.
Manual rotation cursor, in cursor drives, dagger rotates, interior dagger and casing are threaded connection and make rotary motion transfer linear motion to, interior dagger front end is conical structure, nose cone struts center bridge, two center bridge symmetrical outwards spreadings while pushing down compression spring, and two center bridges push up on part simultaneously, part can be under the effect of tension outside, it is achieved self-centering function.
After part processes, opposite direction rotary motion arm, locating piece produces gap with internal stay intercolumniation, and under the effect of compression spring bounce, locating piece is pushed back to original position, it is achieved the function automatically shunk.
The beneficial effects of the utility model are: simple in construction, easy to maintenance, save expense, failure rate is low, interior support force can be with Non-follow control.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is front view of the present utility model.
Fig. 2 is left view of the present utility model.
Fig. 3 is top view of the present utility model.
In figure: 1. casing, 2. center bridge, 3. in dagger, 4. spring stop, 5. compression spring, 6. cursor.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further elaborated.
Embodiment 1
As Figure 1-3, by center bridge (2), that compression spring (5) is placed on casing (1) is inner, is fixed on casing (1) by spring stop (4) with screw, and interior dagger (3) is screwed on casing (1), and cursor (6) is set on interior dagger.
Manual rotation cursor (6), in cursor (6) drives, dagger (3) rotates, interior dagger (3) and casing (1) are threaded connection and make rotary motion transfer linear motion to, interior dagger (3) front end is conical structure, nose cone struts center bridge (2), two center bridge (2) symmetrical outwards spreadings while pushing down compression spring, and two center bridges (2) are pushed up on part simultaneously, part can be under the effect of tension outside, it is achieved self-centering function.
After part processes, opposite direction rotary motion arm (6), produce gap between locating piece (2) and interior dagger (3), under the effect of compression spring bounce, locating piece (2) is pushed back to original position, it is achieved the function automatically shunk.
Claims (3)
1. a self-centering jacking mechanism, it is characterised in that include casing, center bridge, interior dagger, spring stop, compression spring, cursor；Arranging two boss about center bridge one end, the other end is provided with a chamfering, and two center bridge chamfering one end contact and are placed in casing center, forms a chamber with casing at two center bridge chamfer contact, and spring stop is fixed on casing dual-side；Compression spring is placed in the cavity that boss, casing and spring stop surround, and internal stay male screw is connected on casing, and interior dagger nose circle pyramidal structure is placed in the chamber of two center bridge joints, and cursor is vertical with interior dagger to be connected.
