Description
Technical field
The present invention relates to field of fixtures, and in particular to a kind of fixture for shape extrusion.
Background technology
Section bar is widely used in building and mechanical structure field, and fast using section bar construction speed, floor space is small,
And it is suitable for all-weather construction, climate condition influences small.Speed of application with the section bar of steel is about concrete structure construction
2-3 times of speed, the rate of capital turnover significantly improves, and financial expenses is reduced, so as to reduce investment outlay.
In actual use, section bar needs the secondary operation such as punched, cut, due to the special construction of section bar,
There is dead slot so that there is no support meanss inside some positions of section bar, cannot get internal support, to these portions on section bar
When position is drilled or cut, the different degrees of deformation of section bar can be caused so that the mechanical properties decrease of section bar, to building
Quality or the structure of machinery bring detrimental effect.
The content of the invention
For in the prior art the defects of, the present invention provide a kind of fixture for shape extrusion, using multipair primary push rod
Support improves the positioning precision of section bar, and the vertical direction of section bar can also be entered while horizontal direction clamping is carried out to section bar
Row clamping brace, prevents section bar from producing deformation during secondary operation, improves the machining accuracy of section bar.
A kind of fixture for shape extrusion provided by the invention, including mounting seat and be arranged in mounting seat
Clamping device, is provided with the clamping slot for clamping section bar in the mounting seat, and the clamping device includes multiple symmetrically setting
The clamp jaw of clamping slot both sides is placed in, the clamp jaw includes primary push rod and rotates the expansion for being arranged at both sides above and below primary push rod
Bar, the expanding bar with the flexible of primary push rod and relaxation, the end set of the expanding bar have compact heap, the primary push rod passes through
The power set being arranged in mounting seat promote.Primary push rod travel forward push against section bar when, expanding bar with primary push rod fortune
It is dynamic and the top and bottom in section bar dead slot will be propped up, reach and carried out that horizontal plane is fixed and vertical plane is fixed to section bar simultaneously
Purpose.
Alternatively, the bottom of the expanding bar is provided with drive gear, is provided with the primary push rod and drive gear phase
The bar shaped gear of engagement.Using gear engagement by the way of, can ensure expanding bar can quick response and also movement locus it is reliable,
When primary push rod is retracted, expanding bar can shrink simultaneously.
Alternatively, the power set are pneumatic cylinder.Pneumatic cylinder can apply pressure to primary push rod always, ensure primary push rod
Firmly section bar can be clamped.
Alternatively, the compact heap is arranged in expanding bar by ball pivot, and the length direction of the compact heap is perpendicular to master
The length direction of push rod.For ensureing that pressure can be all applied on section bar without producing horizontal component by compact heap, avoid
Section bar is pushed away askew and deviates predetermined position location, improves the positioning precision of section bar.
Alternatively, the return spring for reset is provided with the primary push rod, one end of the return spring, which is arranged at, to be promoted mainly
On bar, the other end is fixed in mounting seat.When being clamped operation to primary push rod using pneumatic cylinder, it is impossible to which primary push rod is produced
Raw pulling force, resulting in primary push rod can not reset after clamping is terminated, and return spring is just used to retract the primary push rod for terminating clamping
Reset.
Alternatively, the bottom of the expanding bar is additionally provided with the ratchet for locking expanding bar, turns on the clamping device
It is dynamic to be provided with the ratchet being engaged with ratchet.The ratchet and pawl is used to fix expanding bar, avoids expanding bar from losing external force
When shrink and lose the supporting role to section bar.
Alternatively, the relieving mechanism for discharging ratchet, the relieving mechanism connection are additionally provided with the clamping device
In on ratchet.When needing to withdraw clamping device, ratchet is discharged by relieving mechanism, ensures that expanding bar can normally be withdrawn.
Alternatively, for the primary push rod perpendicular to the length direction of clamping slot, the primary push rod of clamping slot both sides is relative one by one.With
Both sides stress equalization when section bar is ensured in clamping, is avoided because unbalance stress produces deformation.
Alternatively, the power set include screw rod and the motor for drive screw rotation, and the screw rod is with promoting mainly
Bar is flexibly connected.When being rotationally advancing, primary push rod is pushed forward to move along a straight line the screw rod, and screw rod is with primary push rod using work
Dynamic connection, for ensureing that primary push rod does not rotate with primary push rod.
As shown from the above technical solution, a kind of fixture for shape extrusion provided by the invention, including for section bar
Carry out the primary push rod of horizontal support and the expanding bar for supporting section bar vertically, the expanding bar are transported with the motion of primary push rod
It is dynamic so that clamping process is simple and reliable, and the expanding bar is additionally provided with the spine for preventing expanding bar from surprisingly being shunk when clamping
Take turns, the compact heap set in expanding bar can carry out the support of vertical direction to section bar, avoid section bar from being produced in process engineering
Deformation.
