Description
Technical field
The utility model relates to deviation correcting device field, specifically a kind of correction framework worked in above material.
Background technology
On the coil production lines such as such as papermaking, weaving, film, because sideslip can occur material, need to use deviation correcting device to be corrected.Deviation correcting device is according to the side-play amount detected, control and drive system frequently adjusts the pendulum angle of correction framework upper roller, makes the material covered at roller surface get back to tram.
Swing flexibly for enabling correction framework, common structure is as shown in Figure 1: on frame base 1, install a self-aligning ball bearing 4 and two common ball-bearing casings 3, self-aligning ball bearing 4 is hinged with roller base 2, and roller base 2 relies on Action of Gravity Field to be pressed on the outer ring periphery of two ball-bearing casings 3.During work, be arranged on actuator 5 on frame base 1 by control command push-and-pull roller base 2, roller base 2, for the center of circle periphery of two ball-bearing casings 3 rolls with the center-point of self-aligning ball bearing 4, thus makes roller 6 synchronous hunting of mounted thereto.
Said structure is connected with roller base 2 reality owing to only having self-aligning ball bearing 4, roller base 2 needs to rely on Action of Gravity Field just can be supported on the outer ring periphery of two ball-bearing casings 3, so just can there be 3 stable strong points the top (end position is at right angle setting) that roller base 2 must be made to be arranged on frame base 1, now material can only cover on the surface of roller 6 from top.When the integral layout of production facilities requires that roller 6 is rectified a deviation above material, when namely requiring that roller 6 is arranged on the below of frame base 1, be arranged on three bearings on frame base 1 all to need and roller base 2 physical connection securely, bear weight, the structure shown in Fig. 1 cannot meet the demands.If two ball-bearing casings 3 are replaced with prefabricated circular arc type spherical guide be arranged on roller base 2, although the requirement that can meet configuration aspects exists two problems: one is that cost is very high; Two is alerting abilitys that slight distortion all can reduce motion.

Detailed description of the invention
As Fig. 2, shown in Fig. 5, a kind of correction framework worked in above material, include frame base 1 and be suspended to the roller base 2 below frame base 1, roller base 2 is rotatablely equipped with the roller 6 that two central axis are parallel to each other, frame base 1 is slidably fitted with movable axis 9 by a pair ball bearing guide bushing 12, movable axis 9 central axis and two roller 6 centerline axis parallel, frame base 1 is also installed with two anchor shafts 7 respectively by fixing axle bed 8, equicrural triangle is formed centrally in two anchor shaft 7 centers and movable axis 9, and two anchor shaft 7 central axis overlap with the isosceles limit of equicrural triangle respectively, also include three plain radial bearings 11, one of them plain radial bearing inner ring is fixed on movable axis 9 midway location, all the other two plain radial bearing inner rings respectively one_to_one corresponding are slidably mounted on two anchor shafts 7, three plain radial bearing 11 outer rings are fixed on roller base 2 respectively by screw 10, roller base 2 is also provided with actuator 5, actuator 5 is fixedly connected with movable axis 9.
Actuator 5 is electric expansion bar, electric expansion bar central axis and movable axis 9 centerline axis parallel, and electric expansion bar rod end is fixedly connected with movable axis 9 one end by connecting panel 13.
The mid point of mid point and movable axis 9 that frame base 1 arranges two anchor shafts 7 and a movable axis 9, two anchor shafts 7 forms equicrural triangle.Anchor shaft 7 is fixed by the fixing axle bed 8 be arranged on frame base 1; Movable axis 9 is supported by two ball bearing guide bushings 12 be arranged on frame base 1, can sway.On two anchor shafts 7, each suit plain radial bearing 11, can move vertically; On movable axis 9 install plain radial bearing 11 be fixed on axle center, can with axle synchronizing moving.The outer ring of three plain radial bearings 11 is fixedly connected with roller base 2 with screw 10 respectively, and form three fulcrums of equicrural triangle, roller base 2 is suspended in below frame base 1, and roller 6 covers on material from above.
For reducing the axial dimension of device, the not direct sliding active axle 9 of actuator 5 moves, but by connecting panel 13, the telescopic shaft of actuator 5 and movable axis 9 is coupled together.During work, actuator 5 drives movable axis 9 to move linearly by control command by push-and-pull connecting panel 13, because the plain radial bearing 11 be fixed on movable axis 9 is also fixedly connected with roller base 2 simultaneously, the fulcrum being equivalent to roller base 2 moves along a straight line, according to foregoing principle, two other fulcrum and plain radial bearing 11 also straight-line motion on anchor shaft 7 respectively, the straight-line motion of three fixed pivots makes roller base 2 produce a swing, just the material covered below is made to be shifted with the roller 6 of roller base 2 synchronous hunting, get back to tram.
As shown in Figure 3, Figure 4.In the utility model, correction is realized by the swing of correction framework upper roller, generally require that the correction range of deviation correcting device is more limited, roller needs the angle swung within 5 °, therefore can substitute circular motion with the straight-line motion of each fulcrum when pendulum radius is larger, this spline structure easily realizes and also cost lower.
Utilize the special geometric of equicrural triangle, when the equal moving linearly in leg-of-mutton three summits, leg-of-mutton shape and size remain unchanged, and the path of motion of triangle entirety is similar to the rotation around an attachment point.As shown in Figure 2: when the summit A of triangle ABC is linearly moved to A ＇ or A ＂ point to left or right, summit B and C is linearly moved to B ＇ or B ＂ point and C ＇ or C ＂ point along triangle stringcourse respectively, now triangle A ＇ B ＇ C ＇ and triangle A ＂ B ＂ C ＂ and triangle ABC congruence, and deflected certain angle to the left or to the right relative to O point.
When the fixed pivot of three on roller base is by above-mentioned requirements design and installation, the motion of actuator push-and-pull fixed pivot, roller base is also extremely similar to the plane rocking required by correction together with the path of motion of roller above.
In actual design, the center-point of what three fixed pivots were corresponding is three backup bearings, bearing is fixed on the back side of roller base by bearing seat, as can be seen from Figure 3, after inner ring (the being equivalent to bearing center point) certain distance that moves along a straight line of three bearings, roller base there occurs the swing relative to O point, drive three outside race (the being equivalent to bearing seat) synchronous axial system be fixed in the above, the utility model adopts bearing inner ring and the relatively turnable plain radial bearing of outside race as backup bearing.
For bearing inner ring, move along a straight line the slip that can be converted on axle, and in order to make motion flexible, the friction reducing bearing inner ring and axle is crucial, scheme of the present utility model is: bearing inner ring adopts the engineering plastics with self-lubricating function, and axle adopts stainless steel material.
The motion of actuator direct push-and-pull bearing inner ring is structurally implemented more difficult, and scheme of the present utility model is that the inner ring of one of them plain radial bearing and axle are fixed, and actuator reaches the object of push-and-pull bearing inner ring by push-pull shaft.
