Description
Technical field
The utility model relates to a kind of section straightener, the special universal coupling with spider of especially a kind of straightening machine.
Background technique
Section straightener, is in shaped steel production process, the equipment adopting in the time that curling operation is aligned later.Straightening machine upper and lower position is provided with row's fixed roll, and top position correspondence is provided with the pressure roller that can depress, and when work, pressure roller two ends press down and realize the aligning to shaped steel between fixed roll and pressure roller under power mechanism effect.
Described power mechanism, comprise that one is horizontally disposed with universal coupling with spider up in the same way with pressure roller, coupling two ends are connected with vertically separately one and depress worm screw, the worm screw orientation assemble that is connected with a joggle separately of depressing at two ends is depressed worm gear in frame, depress worm gear internal thread socket and be combined with a vertical down screw rod arranging, down screw rod lower end is connected with pressure roller and realizes the lower pressure-controlled to pressure roller.The power source of power mechanism provides by a motor being fixed in frame, and motor output end is depressed worm screw and is connected power is provided with one, leans on the connection for transmission of coupling to realize the synchronization control to pressure roller two ends pressing action.Wherein, the coupling adopting is common cross-axle universal shaft coupling shaft, comprise a coupling shaft, coupling shaft two ends key is connected with an axle head connecting sleeve, two axle head connecting sleeves connect a driving end connecting sleeve by the rectangle contiguous block of a band dislocation cross attachment hole separately, and axle head connecting sleeve and driving end connecting sleeve form the structure of cross connecting head.
This existing power mechanism, there is following defect: 1, straightening machine uses time vibrations very large, and shaped steel width is larger simultaneously, therefore cause using after a period of time, easily there is high low head in pressure roller two ends, pressure roller can not keep level just to affect beam straightening quality like this; Therefore need to regulate the pressure roller maintenance level again that makes to the cooperation position between down screw rod and worm gear.In the time regulating need to adjustable side depress worm screw and coupling shaft is dismantled, and then cause needing dismounting couplers entirety, it is very inconvenient and consuming time longer to dismantle; While ressembling after dismounting simultaneously, because pressure roller two ends distance is longer, when assemble at coupling two ends, due to the accumulation of error, can cause assembling time there is a larger error in the size of coupling coupling shaft length direction and two ends assembling point distance, and then cause assembling also very difficult and consuming time very long.2, in existing coupling, in the cross connecting head structure at coupling shaft two ends, between axle head connecting sleeve and driving end connecting sleeve and rectangle contiguous block, be to have strong market potential and add the mounting type of Bolt Connection by two, have strong market potential for two and realize and being connected with the attachment hole on rectangle contiguous block through the hole on connecting sleeve respectively., there is distortion because coupling transmitting torque more usually causes connecting sleeve in this mode, therefore be difficult to extract after the distortion of having strong market potential while dismounting, it is very inconvenient and consuming time to dismantle.
Model utility content
For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is: how to provide one can improve handling convenience, save the special universal coupling with spider of straightening machine of lay day.
In order to solve the problems of the technologies described above, in the utility model, adopt following technological scheme:
The special universal coupling with spider of a kind of straightening machine, comprise a coupling shaft, coupling shaft two ends key is connected with an axle head connecting sleeve, two axle head connecting sleeves connect a driving end connecting sleeve by a rectangle contiguous block separately, axle head connecting sleeve and driving end connecting sleeve form the structure of cross connecting head, it is characterized in that, in the structure of described cross connecting head, described rectangle contiguous block is positioned at the connecting end of the U-shaped structure of described axle head connecting sleeve and driving end connecting sleeve, and on rectangle contiguous block, have and be positioned at conplane cross attachment hole, on the connecting end of described axle head connecting sleeve and driving end connecting sleeve, be respectively provided with and perforation corresponding to rectangle contiguous block cross attachment hole, the structure of cross connecting head also comprises that one is had strong market potential and two short pins, described having strong market potential connects into cross through the perforation on axle head connecting sleeve and driving end connecting sleeve and the cross bore on rectangle attachment hole respectively with short pin.
In the utility model, two connections of having strong market potential of cross connecting head change two short pins into and add a Placement of having strong market potential, can first dismantle two short pins when dismounting like this, dismounting is had strong market potential again, very convenient Quick labor-saving, avoids with the first two structure that shifts to install defect that distortion is difficult to dismounting that causes having strong market potential of having strong market potential.
As optimization, described two short pins are that tube-in-tube structure and internal surface are provided with internal thread.
After optimizing like this, while dismantling short pin, can lean on the bolt of coupling to be screwed in the endoporus of short pin, then by pulling bolt to realize the dismounting of short pin, make its dismounting more efficient and convenient laborsaving.
As further optimization, on the connecting end surface of described axle head connecting sleeve and driving end connecting sleeve, also run through to be provided with to be radially inserted into and have strong market potential or the lock screw that locks short pin inside.
While making to install like this short pin and have strong market potential fixing more reliable and stable.
As further optimization, described coupling shaft is made up of the semiaxis of two docking, surface, two semiaxis butt ends direct-axis is to being provided with spline and coordinating with a spline housing being socketed on butt end, on two semiaxis, respectively there is a diameter and become large thread section, on two thread sections, screw-thread fit is socketed with a sleeve separately, the opposite end of two sleeves is connected to respectively two end surfaces of spline housing, described sleeve outer surface has a circle boss, is radially relatively set with at least one pair of polygonal hole on boss.
After optimizing like this, coupling shaft is that two semiaxis dock and form by spline housing, while work like this, between spline housing and two semiaxis, adopts spline fitted can realize the transmission of moment of torsion.When adjustment pressure roller need to be dismantled, can first unclamp away from the direction rotation of spline housing past the sleeve of adjusting end, and spline housing is moved two semiaxis are disconnected completely toward this direction, the structure of the Hooks coupling universal coupling the other end can maintain static like this, makes its convenient disassembly and saves time.Also more quick and can lean between two semiaxis butt ends size error when preset clearance is guaranteed to assemble in the time ressembling, avoid because alignment error causes installing inconvenient defect.
Meanwhile, described sleeve outer surface has a circle boss, is radially relatively set with at least one pair of polygonal hole on boss.While making dismounting and assembling, can lean on two to be inserted in polygonal hole and to realize the rotation dismounting to sleeve with the polygonal steel bar (referring to that cross section is polygonal) of polygonal hole coupling, facilitate the application of force, make its dismounting convenient power-saving more.
In sum, the utlity model has simple in structurely, it is convenient to implement, with low cost, can improve handling convenience, saves the advantages such as lay day.
