On fixed floor, it is connected with fixture retainer.Promoting mainly cylinder pushing assistant cylinder collective effect can realize in workpiece in tooling
Middle positioning.
In one embodiment, a kind of compact Pneumatic fixture has 1 station, can fix a work every time
Part.
In one embodiment, a kind of compact Pneumatic fixture has at least two station, can at least consolidate every time
Fixed 2 workpiece.
In one embodiment, fixture retainer limits the degree of freedom of fixture retained part, fixture retained part intelligence
It can move in a straight line, the conversion of motion of cylinder is the linear motion of fixture retained part.
In one embodiment, self-locking can be realized by gas circuit connection, can be firmly embraced external pressure is zero
Clamping of workpieces.It pushes assistant cylinder 7 and forms an entirety with pressing plate, stretching and the retraction of cylinder are converted into clamping and the pine of pressing plate
It opens.
In one embodiment, forward support block and aft support block collective effect, can coordinate and adjust out different supports
Height being capable of suitable for different-thickness workpiece.
In one embodiment, fixture retained part is processed into V-shape with workpiece locating piece, is clamped by adjusting fixture
Part and locating piece 8, with changing V-shaped varicose degree can be suitable for the workpiece of different in width.
By above technical scheme, beneficial effects of the present invention are:Fixture retained part and forward support block, aft support block
Mutual cooperation expands the range being actually clamped, and disclosure satisfy that the actual processing request of most of part;Entire fixture is in cylinder
Automatic-clamping is realized under effect, it is automatic to unclamp, the reliability of fixture is improved, in operation process, is put into workpiece and taking-up
The improved efficiency of workpiece;All by pneumatic control, the leakage for avoiding workpiece clamps whole process, reduces the mistake in operation process
Accidentally, the retained part and locating piece of fixture can be adjusted according to specification of workpieces, expand the scope of application of fixture.
