Collet two is fixed on slide two.
Fixing bolt one is threadedly coupled after passing through adjustment hole one with slide one, fixing bolt two after the adjustment hole two with cunning
Seat two is threadedly coupled.Unscrew fixing bolt one, collet one is made to be slided in one upper edge draw runner one of draw runner, adjusts collet one in slide one
On position, then fixing bolt one is tightened again, collet one is fixed on slide one.Similarly, unscrew fixing bolt two, make
Collet two is slided in two upper edge draw runner two of draw runner, is adjusted position of the collet two on slide two, is then again twisted fixing bolt two
Tightly collet two is fixed on slide two.Draw runner one and draw runner two are arranged along the direction of sliding rail, fast can accurately pass through
The position of collet one and collet two is adjusted to adjust the distance between collet one and collet two, drive rod is made to rotate smaller angle
Workpiece clamping can be ensured the clamping effect of fixture, while also making tune to make fixture have higher clamping force under degree
Section process is convenient and efficient, is conducive to the use of fixture.
In above-mentioned fixture, all has and be obliquely installed and inclined surface one upward on the two sides of the draw runner one, institute
The confined planes one for having on the side wall of sliding slot one and being correspondingly arranged with inclined surface one are stated, the confined planes one recline with inclined surface one；
It all has and is obliquely installed and inclined surface two upward on the two sides of the draw runner two, have and incline on the side wall of the sliding slot two
The confined planes two that inclined-plane two is correspondingly arranged, the confined planes two recline with inclined surface two.
Confined planes one recline with inclined surface one and confined planes two recline with inclined surface two, can prevent collet one and collet
Two shake during adjusting sliding, and avoiding shaking makes the change of two relative position of collet one and collet cause to incite somebody to action
The problem of Workpiece clamping, to ensure the clamping effect between collet one and collet two.And two court of inclined surface one and inclined surface
On be obliquely installed, have during collet one and slide one are installed and during collet one is installed with slide two and be oriented to
Effect, makes draw runner one successfully be embedded into sliding slot one, draw runner two is made successfully to be embedded into sliding slot two, is advantageously implemented quickly
Replace that installation folder is first and collet two.
In above-mentioned fixture, one end opposite with collet two is bare terminal end one, the bare terminal end one on the collet one
Upper have a V-shaped holding tank one, and one end opposite with collet one is bare terminal end two on the collet two, on the bare terminal end two

Part 8 clamps, while the first 3d of additional lock and auxiliary collet two 4d is close to each other clamps the part to be cut of workpiece 8, then
8 part to be cut of workpiece is cut in cutting machine work, completes cutting.Actuator reversely pulls force side 2b later, makes force side 2b
It is rotated to the direction far from sliding rail 1, drive rod 2 rotates backward, and one 3a of slide and two 4a of slide are slided opposite to each other, one 3b of collet and folder
First two 4b unclamps workpiece 8, and the first 3d of additional lock and auxiliary two 4d of collet unclamp the cutout of workpiece 8.
Since connecting rod 1 and connecting rod 26 are hinged on the hinged end 2a of drive rod 2, by the leverage of drive rod 2,
So that the clamping force between two 4b of one 3b of collet and collet is more than the driving force born on the 2b of force side, improves the clamping effect of fixture
Fruit.Simultaneously drive rod 2 it is substantially vertical with sliding rail 1, connecting rod 26 is substantially vertical with drive rod 2 two, and the position of two 4a of slide and
As soon as the position of two 4b of collet 3b and collet is adjustable, drive rod 2 is enable to clamp workpiece 8 when rotating smaller angle,
So that clamping force is maintained near maximum value, advantageously ensures that the clamping effect of fixture.And the first 3d of additional lock and auxiliary collet two
The setting of 4d prevents 8 part to be cut of workpiece that burr caused by overturning occurs in cutting process, ensure that the cutting matter of workpiece 8
Amount.
