Description
Technical field
The utility model relates to a kind of roll shaft axis adjusting device.
Background technology
At present, the large, medium and small type section straightener that is using is staggered the layout by upper and lower two row's smoothing rolls and constitutes, wherein row's smoothing roll installs that (position that refers to the relative frame of smoothing roll that installs does not herein change, circumferencial direction can rotate) on frame, another row's relative position is adjustable, in order to realize the adjustment of repeatedly alternating bending and press-bending amount, satisfy the required press-bending scheme of aligning.
Straightener can be packed in the row's of going up roller on the frame, adjust the press-bending amount by the relative position of adjusting lower roll, but, consider varying in size and the wearing and tearing of smoothing roll circle of product specification, at present the axis of arranging smoothing roll at aligning needs to adjust, to adapt to the production line height, for this reason, increase by a cover straightener integral elevating device usually and solve.So, when the design straightener, in order to reduce weight of equipment, usually lower roll is packed on the frame, adjust the press-bending amount by the relative position of adjusting row's roller.
Lower roll be packed in nine rollers on the frame (pattern of R1 ~ R9) be example the straightener schematic diagram as shown in Figure 1, wherein R1, R2 and R3 constitute first aligning triangle, by that analogy, R6, R7 and R8 constitute the 6th aligning triangle, and R7, R8 and R9 constitute last aligning triangle.As can be seen from Figure 1, can adjust last by adjustment R8 distance in vertical direction and align leg-of-mutton press-bending amount, at this moment, the 6th the leg-of-mutton press-bending amount of aligning also produced variation.For this reason, 8 rollers+1 roller or 9 rollers+1 roller etc. increase a help roll in original aligning back straightener has appearred.The smoothing roll that increases is arranged on the straightener by increasing other devices, has increased weight of equipment; For large-scale straightener, there is the problem of insufficient rigidity; In addition, the smoothing roll that exist to increase such as can only adjust in one direction at deficiency.
The utility model content
The purpose of this utility model is to provide a kind of roll shaft axis adjusting device to adjust the last roller of straightener.By adjusting the position of last roller on level and vertical direction, be implemented in and guarantee that other are aligned and adjust last under the prerequisite that leg-of-mutton press-bending amount is not affected and align leg-of-mutton press-bending amount.Thereby reach the purpose that reduces weight of equipment, improves straightening quality.
To achieve these goals, by the following technical solutions: a kind of roll shaft axis adjusting device, it is characterized in that: described device comprises the gear eccentric bushing, be processed with gear on the described gear eccentric bushing, the inner hole centreline of gear compound graduation circle center line and gear eccentric bushing has offset, described gear eccentric bushing is installed in the installing hole of frame, the center line of frame installing hole and described gear eccentric sleeving gear reference circle central lines; By bearing roll shaft is housed, the inner hole centreline of gear eccentric bushing and the dead in line of roll shaft in the gear eccentric bushing endoporus; Gear shaft is installed in the frame by second bearing, the gear engagement of the gear of gear shaft and described gear eccentric bushing, and the other end of gear shaft is equipped with reducing motor.
The side that described gear shaft is equipped with reducing motor is equipped with the number of turns that encoder is measured the gear shaft rotation, and protective cover is installed on the reducing motor, in order to protect encoder.
Be provided with lining between described gear eccentric bushing and the frame.
When needs are adjusted the axial location of roll shaft, rotate by reducing motor driven gear axle, gear engagement because of the gear of gear shaft and gear eccentric bushing, thereby the driven gear eccentric bushing is around the rotation of gear compound graduation circle center line, because of the reference circle center line of moving gear eccentric sleeving gear and the inner hole centreline of gear eccentric bushing eccentric amount e is arranged again, so, the axis of roll shaft can be the center of circle with the reference circle center line of gear eccentric sleeving gear, eccentric amount e is radius around the reference circle center line rotation of gear eccentric sleeving gear, thereby realizes adjustment function to press-bending amount or roll spacing in the position in a circumferential direction by adjusting the roll shaft axis.
The utility model can accurately be adjusted the position of level and the vertical direction of smoothing roll roll shaft, thereby makes that the press-bending amount of last aligning unit is more reasonable under the prerequisite that does not influence other aligning triangle press-bending amounts, and adjusting range is wider, has improved product quality.The utility model is directly installed in the frame, makes device structure compacter, can effectively alleviate weight of equipment.
