Description
Technical field
The present invention relates to machining fixture field, and in particular to one kind automatically resets assistant supporting mechanism.
Background technology
Machine industry is generally fixed to workpiece using fixture, supported in process.The auxiliary of fixture
Supporting structure is the common structure of fixture, is typically to promote the inclined-plane on ejector pin, ejector pin to compress on support column with lateral screw
Inclined-plane, so as to lock support column, i.e., ejector pin locking support column rear support post is not active, and ejector pin can be moved when unclamping screw rod, props up
Platen can be moved up and down.
But during actual processing, workpiece has smile due to the reasons such as stress, processing heat, workpiece local location
Change, and the support column of aiding support is not active after being lockable, and causes to produce gap between support column and workpiece, so as to cause auxiliary
Supporting is helped to fail.
The content of the invention
In order to solve the above technical problems, it is an object of the invention to provide the auxiliary support mechanism that automatically resets.
Technical scheme is as follows：
Automatically reset assistant supporting mechanism, including fulcrum bearing（1）, oil cylinder（2）, positioning sleeve（3）, piston rod（4）, push rod（5）, swallow
Tail voussoir（8）, dovetail guide rod（10）, screw rod（12）, it is characterised in that：
The fulcrum bearing（1）It is arranged on inside clamp body, is hollow structure, there is the holes that transverse and longitudinal is vertical, the oil cylinder（2）Pass through
Positioning sleeve（3）Fixing device is in the fulcrum bearing（1）In horizontal hole, the oil cylinder（2）With piston rod（4）It is connected, it is described
Piston rod（4）Front end be provided with push rod（5）, the push rod（6）On be cased with spring（6）, the push rod（5）Front end set cut somebody's hair
（8）, the fulcrum bearing（1）The spacer being adapted with aperture is set in horizontal hole（13）, the dovetail voussoir（8）Installed in institute
State spacer（13）It is interior, the fulcrum bearing（1）The flange sleeve being adapted with aperture is set in longitudinal bore（9）, the dovetail guiding
Bar（10）It is arranged on the flange sleeve（9）The interior and dovetail voussoir（8）Match, the screw rod（12）With the dovetail guide rod
（10）Pass through nut（14）Threaded connection.
Further, the spacer（13）By screw in the fulcrum bearing（1）It is fixed in horizontal hole, carry out spacing.
Further, the flange sleeve（9）Upper end and the guide rod（10）Between dust ring is set（11）.
Further, the dovetail guide rod（10）With the dovetail voussoir（8）Contact surface be self-locking angle.
Further, the push rod（5）With the dovetail voussoir（9）Between by cutting somebody's hair（7）Promote.
By such scheme, the present invention at least has advantages below：
Connected between guide rod and voussoir of the present invention by dovetail, compared with other forms, more compact structure is stable and reliable in work；Pushing away
Spring is set to support workpiece on bar, it is possible to reduce because of the bearing position of oil cylinder dynamic effect workpiece；Dovetail guide rod 7 and dovetail
The contact surface of voussoir 5 is self-locking angle, and contact rigidity is high, can bear any axial force of screw rod；Screw rod 9 and dovetail guide rod 7
It is thread connection, height can be adjusted by rotary screw and tightened with nut, it is to avoid because workpiece local location floats what is produced
Cause the problem of aiding support fails in space between workpiece.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
In figure：1- clamp bodies, 2- oil cylinders, 3- positioning sleeves, 4- piston rods, 5- push rods, 6- springs, 7- cuts somebody's hair, 8- dovetail voussoirs, 9-
Flange sleeve, 10- dovetail guide rods, 11- dust rings, 12- screw rods, 13- spacers, 14- nuts.
Embodiment
With reference to the accompanying drawings and examples, the embodiment to the present invention is described in further detail.Implement below
Example is used to illustrate the present invention, but is not limited to the scope of the present invention.
As shown in figure 1, the assistant supporting mechanism that automatically resets described in a preferred embodiment of the present invention, including fulcrum bearing 1, oil
Cylinder 2, positioning sleeve 3, piston rod 4, push rod 5, dovetail voussoir 8, dovetail guide rod 10, screw rod 12, the fulcrum bearing 1 is arranged on fixture
Internal portion, is hollow structure, has the holes that transverse and longitudinal is vertical, the oil cylinder 2 is by the fixing device of positioning sleeve 3 in the fulcrum bearing 1
In horizontal hole, the oil cylinder 2 is connected with piston rod 4, and the front end of the piston rod 4, which is provided with push rod 5, the push rod 6, to be covered
There is a spring 6, the front end of the push rod 5, which is set, cuts somebody's hair 7, and 7 promotions of cutting somebody's hair are passed through between the push rod 5 and the dovetail voussoir 9.
The spacer 13 being adapted with aperture is set in the horizontal hole of fulcrum bearing 1, the dovetail voussoir 8 is arranged on described
The flange sleeve 9 being adapted with aperture is set in spacer 13, in the longitudinal bore of fulcrum bearing 1, and the dovetail guide rod 10 is set
Match in the flange sleeve 9 with the dovetail voussoir 8, connected between guide rod and voussoir by dovetail, compared with other forms, structure
It is more compact, it is stable and reliable in work.
The screw rod 12 is threadedly coupled with the dovetail guide rod 10 by nut 14, and height can be adjusted by rotary screw
Spend and tightened with nut, it is to avoid the aiding support failure caused by workpiece local location floats the space between workpiece produced
Problem.
The spacer 13 is fixed by screw in the horizontal hole of the fulcrum bearing 1, is carried out spacing.In the flange sleeve 9
Konisphere 11 is set between end and the guide rod 10.The contact surface of the dovetail guide rod 10 and the dovetail voussoir 8 is Self-locking angle
Degree, contact rigidity is high, can bear any axial force of screw rod.
In the course of the work, oil cylinder 2 is by driving piston rod 4 to deliver to push rod 5 foremost, and spring 6 promotes dovetail voussoir 9
Dovetail guide rod 10 is driven to move up and down so that screw rod 12 touches workpiece surface, plays a part of supporting, when being stopped
When, oil cylinder 2 draws back push rod 5, and spring 6 plays automatically reset effect.
