For guaranteeing the smooth slip of bearing block along guide rail, avoid taking place stuck phenomenon, this device also comprises four rolling, described four rolling is located at four jiaos of described bearing blocks respectively by wheel shaft and against described two guide rail sides, when bearing block slides along guide rail, four rolling impels bearing block slippage action more smooth and easy along the guide rail side slip.
For avoiding base plate and adjusting screw(rod) to flexibly connect the wearing and tearing of the adjusting screw(rod) bottom that causes, influence correction precision, this device also comprises wear-resistant sleeve, and described wear-resistant sleeve is located at described adjusting screw(rod) bottom and is flexibly connected with described base plate, and the wearing and tearing of adjusting screw(rod) bottom have been avoided in the setting of wear-resistant sleeve.
Since the rectified a deviation tension release device that the utility model is used for the milling train jockey pulley adopted technique scheme promptly two guide rails be located at two straight-bar inboards of rectangular frame in opposite directions, the bearing block both sides are provided with chute, bearing seat in rectangular frame and the both sides chute move along two guide rails, rectangular frame crossbeam center has screw, adjusting screw(rod) is twisted in the screw of rectangular frame crossbeam, base plate is located at described adjusting screw(rod) bottom and versatilely against the bearing block end face, setscrew nut is twisted on adjusting screw(rod), the connecting axle bearing bottom surface, piston rod top of push-and-pull cylinder.This apparatus structure is simple, and tension adjustment is convenient, by revising coil of strip correction amount manually, has effectively remedied the deficiency of milling train unit centering capacity, has guaranteed the normal operation of milling train unit, has improved production efficiency.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is used for the structural representation of the rectified a deviation tension release device of milling train jockey pulley for the utility model,
Fig. 2 is the structural representation of this device increase wear-resistant sleeve,
The schematic diagram that Fig. 3 uses for this device.
The specific embodiment
As shown in Figure 1, the rectified a deviation tension release device that the utility model is used for the milling train jockey pulley comprises the bearing block 2 of being located at the jockey pulley two ends by bearing 1, also comprise rectangular frame 3, base plate 4, adjusting screw(rod) 5, setscrew nut 6, push-and-pull cylinder 8 and two guide rails 7, described rectangular frame 3 comprises crossbeam 31 and is vertical at the straight-bar 32 at crossbeam two ends, described two guide rails 7 are located at two straight-bar 32 inboards of described rectangular frame 3 in opposite directions, described bearing block 2 both sides are provided with chute, described bearing block 2 is positioned at described rectangular frame 3 and the both sides chute moves along described two guide rails 7, described rectangular frame 3 crossbeams 31 centers have screw, described adjusting screw(rod) 5 is twisted in the screw of described rectangular frame 3 crossbeams 31, described base plate 4 is located at described adjusting screw(rod) 5 bottoms and versatilely against described bearing block 2 end faces, described setscrew nut 6 is twisted on described adjusting screw(rod) 5, and piston rod 81 tops of described push-and-pull cylinder 8 connect described bearing block 2 bottom surfaces.
For guaranteeing the smooth slip of bearing block 2 along guide rail 7, avoid taking place stuck phenomenon, this device also comprises four rolling 9, described four rolling 9 is located at 2 four jiaos of described bearing blocks respectively by wheel shaft and against described two guide rail 7 sides, when bearing block 2 slides along guide rail 7, four rolling 9 impels bearing block 2 slippages action more smooth and easy along guide rail 7 side slip.
As shown in Figure 2, for avoiding base plate 4 and adjusting screw(rod) 5 to flexibly connect the wearing and tearing of adjusting screw(rod) 5 bottoms that cause, influence correction precision, this device also comprises wear-resistant sleeve 41, described wear-resistant sleeve 41 is located at described adjusting screw(rod) 5 bottoms and is flexibly connected with described base plate 4, and the wearing and tearing of adjusting screw(rod) 5 bottoms in adjustment process have been avoided in the setting of wear-resistant sleeve 41.
As shown in Figure 3, this device is located at the bearing block 2 at jockey pulley 10 two ends in the rectangular frame 3 and by guide rail 7 and chute and is moved along rectangular frame 3, and the be connected base plate of adjusting screw(rod) 5 of bearing block 2 end faces, bearing block 2 bottom surfaces connect push-and-pull cylinder piston rod 81, bearing block 2 under the effect of push-and-pull cylinder piston rod 81 end face against base plate, under the normal condition, the milling train units steel coil is in normal condition under the adjustment of unit deviation correcting device, and when skew takes place the spring tape steel, only need unscrew setscrew nut 6, adjusting screw(rod) 5 is carried out precession, the trace adjustment that screws out, the displacement of adjusting screw(rod) 5 drives base plate and produces displacement, so just can change the position of bearing block 2 and by the effect of cylinder pressure bearing block 2 be remained on the relatively-stationary position.So just make the axis of jockey pulley 10 and the perpendicularity between the spring tape steel center line that a certain amount of skew takes place, thereby reached the purpose of the spring tape steel of rectifying a deviation, release tension force.Consider simultaneously in the correction process because the change of bearing block 2 positions can make the jockey pulley 10 and the axle center of bearing block 2 be offset, produce coaxiality error, there is the stuck possibility of jockey pulley bearing 1, for avoiding the generation of this phenomenon, selecting model by comparison in jockey pulley bearing 1 type selecting is the self-aligning roller bearing of 20000 series, and the type bearing has following advantage: bearing capacity is big, and aligning is good, energy compensating coaxial degree error, limit speed is low.
This device can compensate the correction adjustment of unit deviation correcting device to the band steel, and is simple in structure, easy to adjust, for tension force release and correction in the band steel running provide means easily.
