Fixture is to be used for during machine-building fixing processing object, is allowed to occupy correct position, with receive construction or
The device of detection, also known as fixture.In a broad sense, any process in technical process, for rapidly, easily and safely pacifying
The device of workpiece is filled, fixture is all can be described as.Such as weld jig, inspection jig, assembling jig, jig.Wherein lathe
Fixture is most commonly seen, is often simply called fixture.When processing workpiece on lathe, to enable the surface of workpiece to reach as defined in drawing
Size, geometry and with the technical requirements such as the relative-position error of other surfaces, workpiece must be installed, pressed from both sides before processing
Jail.Fixture is generally by setting element, clamping device, to groups such as knife induction element, indexing means, connecting element and clamp bodies
Into.Existing punch press clamper is typically all that the replacing or fixed of mould is realized by the dismounting of mechanical structure with the structure that mould is positioned
Position, therefore disassembling, assembling and replacing mould is inconvenient, more mold exchange takes considerable time.
Utility model content
The utility model is in view of the shortcomings of the prior art, provide a kind of direct-pulling type hydraulically operated fixture, this kind of direct-pulling type hydraulically operated fixture
Disassembling operations quickly can be carried out to fixture, so as to improve the efficiency of die change.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals：A kind of direct-pulling type liquid
Fixture, including the oil-hydraulic cylinder with plunger shaft are pressed, the oil-hydraulic cylinder bottom is provided with through hole, the through hole and is equipped with T
Piston body, the piston body and the oil-hydraulic cylinder top are provided with profile shaft, the T-shaped axle in the plunger shaft
Between be provided with the middle fuel inlet fitting with passage, the fuel inlet fitting and institute be provided with back-moving spring, the oil-hydraulic cylinder
State and be provided with steam vent at the top of the connection of plunger shaft bottom, the oil-hydraulic cylinder.The direct-pulling type fixture of this structure is T-shaped when in use
Axle is fixed, and during oil-feed oil-hydraulic cylinder is moved down, so as to quickly position mould, when needing more mold exchange, to liquid
Pressure release is pressed oil, now back-moving spring bounce causes oil-hydraulic cylinder to move release mould upwards, can quickly be changed.
In above-mentioned technical proposal, it is preferred that the oil-hydraulic cylinder includes the cylinder of one end open and covered in opening
End cap, the cylindrical groove coordinated with the back-moving spring is provided with the end cap bottom.Oil hydraulic cylinder is caused using this structure
It is convenient in vivo that piston body is installed, positioned while setting cylindrical groove easily can coordinate with back-moving spring.
It is described first annular in above-mentioned technical proposal, it is preferred that be provided with first annular groove in the middle part of the piston body periphery
The first sealing ring is provided with groove.The sealing between piston body and oil-hydraulic cylinder is caused to improve using the structure.
In above-mentioned technical proposal, it is preferred that the piston body lean the back-moving spring end be provided with it is described for engaging
The bulge loop of back-moving spring.Set bulge loop to position between back-moving spring and piston body it is more firm.
In above-mentioned technical proposal, it is preferred that the side in the through hole is provided with the second annular groove, second annular groove
Inside it is provided with the second sealing ring.Better tightness between through hole and the T-shaped axle is caused using the structure.
The utility model compared with prior art, has the advantages that：The direct-pulling type fixture of this structure is being used
When T-shaped axle fix, during oil-feed oil-hydraulic cylinder is moved down, so that quickly mould be positioned, when needing more mold exchange,
To hydraulic oil pressure release, now back-moving spring bounce causes oil-hydraulic cylinder to move release mould upwards, can quickly be changed.
