Abstract
The invention provides a built-in no-side-gap gear angle adjusting device of an inclined roller straightening machine. The adjusting device comprises a straightening roller, a roller base, a rack, an eccentric shaft, a transition gear, a speed reduction motor, a half gear ring, a box body, driving gears, a spring, an adjusting bolt, a positioning bearing and a bearing pedestal, wherein the straightening roller is fixed above the roller base through the bearing pedestal and a plurality of sets of bolts; the roller base is positioned on the inner side of the rack through the positioning bearing; the outer side of the rack is connected with the box body; a shaft of the speed reduction motor is sleeved with the driving gears, and one side of the shaft of the speed reduction motor is provided with the spring and the adjusting bolt; the driving gears can rotate in a meshed mode through the transition gear, the eccentric shaft and the half gear ring under the action of the spring. An included angle exists between the direction of the axis of the strengthening roller of the inclined roller straightening machine and the direction of the length of a strengthened pipe (or rod). When pipe rod materials with different diameters are strengthened and the diameters of the pipe rod materials change within a certain range, the pipe rod materials can be straightened just by changing the included angle without replacing the straightening roller.
Description
Technical field
The present invention relates to a kind of smoothing roll angle regulator of cross-roll straightening machine.Between the smoothing roll axis direction of cross-roll straightening machine and tubing (or bar) length direction aligned, there is an angle.In the time of the bar of aligning different-diameter, only need to change this angle and just can realize in the time that the diameter of bar changes within the specific limits and do not need to change smoothing roll, can realize the aligning to bar.
Background technology
Existing cross-roll straightening machine adjusting angle mechanism mainly contains 2 kinds of modes.(1) connecting-rod mechanism type: the quadric chain that the connecting rod that utilizes of being fixed between the rotating disk of reclining apparatus in slide or frame and fixing smoothing roll or roller seat can change length forms, realize the rotation of rotating disk or roller seat by the length that changes connecting rod, thereby realize the change of roller corner.This mode is usually used on big-and-middle-sized cross-roll straightening machine.For large-scale cross-roll straightening machine, this structure makes floor space excessive because connecting rod is oversize.(2) leading screw driving: use on small-sized straightener, utilize leading screw guiding mechanism to promote to be suspended on the roller seat rotation of frame inside, thereby the smoothing roll corner being fixed on roller seat is rotated, realize the change of smoothing roll angle.In above-mentioned 2 kinds of structures, all exist from the problem of the detected smoothing roll angle of active movement part and a deviation of actual numerical value existence, the accuracy of electric automatization control cannot be embodied.
If can there is a kind of structure, be arranged on the built-in pattern adjusting angle mechanism of frame inside for the roller seat of fixing smoothing roll, as the lower roll assembling form for small-sized straightener and big-and-middle-sized aligning, make the adjustment mode of existing smoothing roll corner can realize accurate transmission and eliminate to detect error and seem particularly important.
As can be seen here, above-mentioned existing cross-roll straightening machine adjusting angle mechanism, in structure and use, obviously still has inconvenience and defect, and is urgently further improved.Therefore how to found a kind of built-in anti backlash gear reclining apparatus of a kind of cross-roll straightening machine of new structure, also becoming the current industry utmost point needs improved target.
Summary of the invention
The object of the invention is to, overcome the defect that existing cross-roll straightening machine adjusting angle mechanism exists, and provide a kind of built-in anti backlash gear reclining apparatus of a kind of cross-roll straightening machine of new structure, technical problem to be solved is on large, medium and small type straightener, to adopt built-in anti backlash gear transmission to adjust mode, not only can realize angle accurately adjusts nor exists in the time that positive and negative both direction changes, occur bringing detection error because gap exists the idle stroke producing, possess certain versatility simultaneously.The present invention has thoroughly eliminated the drive gap between detecting element, active movement part and passive movement part, can realize the precise fine-adjustment of roller corner in the time of rotating and the accuracy of automation control.
The object of the invention to solve the technical problems realizes by the following technical solutions.The built-in anti backlash gear reclining apparatus of a kind of cross-roll straightening machine proposing according to the present invention, comprising: smoothing roll, roller seat, frame, eccentric shaft, transition gear, reducing motor, half-ring gear, casing, driving gear, spring, adjustment bolt, location bearing, bearing block; Described smoothing roll is bolted to roller seat top by bearing block and many groups; Described roller seat is positioned at frame inner side by location bearing; And the outside of frame is connected with described casing; On described reducing motor axle, be arranged with driving gear, and a side is provided with spring and adjusts bolt; Described driving gear passes through transition gear, eccentric shaft, the engageable rotation of half-ring gear under the effect of spring.
The object of the invention to solve the technical problems also can be applied to the following technical measures to achieve further.
