Specific embodiment
In order to clarify the technical characteristics of the invention, below by specific embodiment, and its attached drawing is combined, to this programme
It is illustrated.
Embodiment one:
It can be seen that a kind of two-jaw(ed)chuck fixture, including two-jaw(ed)chuck 1 by attached drawing 1-3, two-jaw(ed)chuck 1 includes chuck
Ontology 11 and two movable jaws 12, two movable jaws 12 are symmetricly set in chuck body 11.Divide on two movable jaws 1
It is not fixed with the first chuck 2 and the second chuck 3, the first chuck 2 two outer surfaces opposite with the second chuck 3 are respectively set useful
In the first holding tank 21 and the second holding tank 31 of clamping workpiece 4, the first holding tank 21 and the second holding tank 31 constitute with it is to be added
The clamping part that the workpiece 4 of work matches.For example, when the shape of workpiece 4 is square, then the first holding tank 21 and the second holding tank
The chamfered shape of 31 compositions is square；When the shape of workpiece 4 is regular hexagon, then the first holding tank 21 and the second holding tank
The chamfered shape of 31 compositions is regular hexagon.Two-jaw(ed)chuck 1 is in use, be inserted into the conelet on two-jaw(ed)chuck 1 for voltaic spanner
Gear square hole 13 is rotated, and the centripetal movement of two movable jaws 12 is driven.First chuck 2 and the second chuck 3 respectively with two
Movable jaw 12 is fixedly connected, and is moved radially using two movable jaws 12 on two-jaw(ed)chuck 1, realizes the first chuck 2 and the
Two chucks 3 move radially, and complete the clamping and release of workpiece 4.First chuck 2 and the second chuck 3 are when clamping workpiece 4, work
Part 4 clamps firm stable, damages in clamping process to the workpiece 4 of clamping smaller.And there is self centering effect, positioning can
It leans on, precision height, it is easy to operate, quick, it is suitble to the mass production of miniature workpiece 4.
In the present embodiment, the first chuck 2 and the second chuck 3 are the column structure of section semicircular in shape.Certainly at other
In embodiment, the section of the first chuck 2 and the second chuck 3 may be other shapes, such as square, rectangle.
It is convenient when to connect the first chuck 2 and the second chuck 3 with movable jaw 12, the first chuck 2 lower surface and
The lower surface of second chuck 3 is provided with and the matched groove 6 of movable jaw 12.As shown in fig. 6, groove 6 is arranged in the first chuck 2
With the middle position of 3 bottom surface of the second chuck, groove 6 has positioning and guiding effect, in the first chuck 2 and the second chuck 3 and activity
When claw 12 connects, groove 6 is matched with movable jaw 12, it is convenient and efficient.In the present embodiment, the first chuck 2 and the second folder
Disk 3 is respectively welded on two movable jaws 12.
In order to keep the first chuck 2 and the second chuck 3 more firm in clamping workpiece 4, in the table of the first holding tank 21
Face and the surface of the second holding tank 31 are provided with lateral anti-skid chequer and longitudinal anti-skid chequer, and lateral anti-skid chequer and longitudinal anti-skid chequer are in
It is staggered.Anti-skid chequer can be improved the frictional force between fixture and workpiece 4, help to improve fixture entirety stability and can
By property.In addition, the surface of the first holding tank 21 and the second holding tank 31 can improve the intensity on clamping part surface by quenching treatment
And hardness, increase its service life.
In the present embodiment, the bottom surface of the chuck body 11 of two-jaw(ed)chuck 1 is provided with multiple threaded mounting holes 14, for side
Just chuck body 11 is fixed in machine table, opens up on the mounting plate of machine table and is installed with the screw thread of 11 bottom surface of chuck body
Chuck body 11 can be fixedly connected in machine table by the compatible bolt hole in hole 14 by bolt.
