Description
Technical field
This utility model is related to mechanical manufacturing field, more particularly, to a kind of clamping fixture.
Background technology
It is often necessary to unclamp after parts are clamped during the production and assembly of product, common clamping fixture
Need operator manually to clamp use, take longer, inefficiency, be unfavorable for the production model of streamline, and other
The complex structure such as some automatization's clamping device such as mechanical hands, assembly and disassembly is inconvenient, and maintaining is relatively costly.
Utility model content
In order to solve the above problems, the purpose of this utility model is to provide that a kind of work efficiency is higher, structure is simple
Clamping fixture.
This utility model employed technical scheme comprise that for solving its technical problem：
A kind of clamping fixture, including the bearing of an inner hollow, is coated with a push-pull bar, described push-and-pull inside described bearing
Bar one end is connected with driving means, and described bearing is rotatably connected to plural jaw, and the other end of described push-pull bar sets
There is the inclined-plane that can contact with described jaw and drive described jaw to rotate relative to described bearing.
Preferably, described jaw is provided with a protuberance, and described protuberance can slide on described inclined-plane.
Preferably, described inclined-plane is taper seat.
Improve further as of the present utility model：Described push-pull bar is provided with a bearing pin, and described bearing is provided with and institute
State the chute that bearing pin is used in combination, inside described bearing, be provided with cavity, described push-pull bar is provided with a spring, this spring
One end is resisted against on described bearing pin, and the other end is resisted against on the end face of described cavity, and described driving means are a cam rotation machine
Structure.
As other embodiment of the present utility model, described driving means are a cylinder or piston cylinder.
The beneficial effects of the utility model are：A kind of clamping fixture of the present utility model include a push-pull bar with inclined-plane and
At least two jaws that can slide on this inclined-plane, and drive push-pull bar to make jaw sliding on inclined-plane using driving means
Dynamic, jaw is realized promptly or is unclamped, this utility model pass through briefly above structure it is achieved that the clamping of jaw and unclamping, work
Efficiency is higher, and assembly and disassembly is convenient, and maintaining cost is relatively low.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the A-A profile of Fig. 1.
Specific embodiment
With reference to the accompanying drawings and detailed description this utility model is described in further detail, however, it is desirable to say
Bright, the explanation to implementation below is schematic, does not constitute to concrete restriction of the present utility model.
See figures.1.and.2, a kind of clamping fixture of the present utility model, including the bearing 1 of an inner hollow, hollow space
For cavity 9, inside described bearing 1, it is coated with a push-pull bar 2, one end of push-pull bar 2 is connected with driving means 3, in the present embodiment
Described in driving means 3 be a Cam drive system, push-pull bar 2 is also hinged with a rolling with one end of cam rotation form touch
Wheel, roller can reduce the end wear of push-pull bar 2 and cam contact position it is ensured that the precision of the stroke of push-pull bar 2.As this
Another embodiment of utility model, described driving means 3 can also be a cylinder or piston cylinder.It is rotatably connected on bearing 1
Plural jaw 4, the quantity of jaw 4 is two, and the quantity of jaw 4 can increase to three according to specific service condition
Or four or more, the other end of push-pull bar 2 is provided with the inclined-plane 5 being used in combination with jaw 4, and this is oblique in the present embodiment
Face 5 is taper seat, each jaw 4 is equipped with a protuberance 6, protuberance 6 can slide on taper seat.Push-pull bar 2 is provided with one
Bearing pin 7, bearing 1 is provided with the chute 8 being used in combination with described bearing pin 7, and bearing pin 7 and chute 8 constitute the stroke of push-pull bar 2
Position-limit mechanism, push-pull bar 2 is provided with a spring 11, and one end of this spring 11 is resisted against on described bearing pin 7, and the other end is resisted against
On the end face of cavity 9, this spring 11 is used for the reseting movement of push-pull bar 2.
When the ledge contact push-pull bar 2 of cam drives push-pull bar 2 to travel forward, spring 11 gathers elastic potential energy,
The end face at the larger end of taper seat backs down jaw 4, the open-shaped state of jaw 4；When cam is rotated further, spring 11 discharges elastic potential
Can help push-pull bar 2 reseting movement backward, the protuberance 6 of jaw 4 along taper seat larger end motion from small end to taper seat,
Jaw 4 is in tightening state.
The foregoing is only preferred embodiments of the present utility model, as long as realizing this utility model with essentially identical means
The technical scheme of purpose broadly falls within protection domain of the present utility model.
