Description
Technical field
The utility model relates to a kind of smoothing roll angle regulator of cross-roll straightening machine, particularly relates to the smoothing roll axis direction of cross-roll straightening machine and is had an angle between tubing (or bar) length direction of aligning.When the pipe bar of aligning different-diameter, when only needing to change a diameter that this angle just can be implemented in the pipe bar and changing within the specific limits and do not need to change smoothing roll, can realize the aligning to the pipe bar.
Background technology
Existing cross-roll straightening machine adjusting angle mechanism mainly contains 2 kinds of modes.(1) linkage formula: utilize the reclining apparatus be fixed on the slide and fixedly between the rotating disk of smoothing roll or the roller seat can change the quadric chain that the connecting rod of length constitutes, 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 the medium-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 the leading screw guiding mechanism to promote to be suspended on the roller seat rotation of frame inside, thereby the smoothing roll corner that will be fixed on the roller seat rotates, and realizes the change of smoothing roll angle.In above-mentioned 2 kinds of structures, all exist from the problem of the detected smoothing roll angle in active movement part place and a deviation of actual numerical value existence, make the accuracy of electric automatization control to embody.
At the problems referred to above, adopt anti backlash gear transmission of the present utility model to adjust mode at large, medium and small straightener, not only can realize accurately adjusting nor when existing in positive and negative both direction and changing, occur bringing the detection error because there is the idle stroke that produces in the gap.The utility model has thoroughly been eliminated the gap between detecting element, active movement part and passive movement part, can realize the accuracy of accurate fine setting and the automation control of roller corner.
This shows that above-mentioned existing cross-roll straightening machine adjusting angle mechanism obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.Therefore how to found a kind of novel 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.
Because the defective that above-mentioned existing cross-roll straightening machine adjusting angle mechanism exists, the inventor is based on being engaged in practical experience and the professional knowledge that this type of product design manufacturing is enriched for many years, and the utilization of cooperation scientific principle, actively studied innovation, in the hope of founding the novel anti backlash gear reclining apparatus of a kind of cross-roll straightening machine of a kind of new structure, can improve general existing cross-roll straightening machine adjusting angle mechanism, make it have more practicality, science.Through constantly research, design, and through repetition test, create the utility model that has practical value finally.
Summary of the invention
The purpose of this utility model is, overcome the defective that existing cross-roll straightening machine adjusting angle mechanism exists, be to make the smoothing roll axis direction of its cross-roll straightening machine and had an angle between tubing (or bar) length direction of aligning and a kind of novel anti backlash gear reclining apparatus of a kind of cross-roll straightening machine of new structure, technical problem to be solved are provided.When the pipe bar of aligning different-diameter, when only needing to change a diameter that this angle just can be implemented in the pipe bar and changing within the specific limits and do not need to change smoothing roll, can realize the aligning of pipe bar is very suitable for practicality.
The purpose of this utility model and solve its technical problem and realize by the following technical solutions.According to the novel anti backlash gear reclining apparatus of a kind of cross-roll straightening machine that the utility model proposes, comprising: slide, positioning core axle, rotating disk, half-ring gear, reducing motor, casing, smoothing roll, driving gear, spring, adjustment bolt; Described smoothing roll is bolted to the rotating disk below by bearing block and many groups; Described rotating disk is fixed on the slide by positioning core axle; The described casing of angle modulation main drive is arranged on the slide and inside is provided with described spring and adjust bolt; Be provided with described half-ring gear between described slide one side and the described rotating disk; Be arranged with described driving gear on the described reducing motor axle and be meshing with each other with described half-ring gear.
The object of the invention to solve the technical problems also can be applied to the following technical measures to achieve further.
The novel anti backlash gear reclining apparatus of aforesaid a kind of cross-roll straightening machine is characterized in that the saddle type that is shaped as of smoothing roll.
The novel anti backlash gear reclining apparatus of aforesaid a kind of cross-roll straightening machine is characterized in that the engagement direction of driving gear and half-ring gear is provided with one group of spring.
The utility model compared with prior art has tangible advantage and beneficial effect.As known from the above, for achieving the above object, the utility model provides a kind of novel anti backlash gear reclining apparatus of cross-roll straightening machine, comprising: slide, positioning core axle, rotating disk, half-ring gear, reducing motor, casing, smoothing roll, driving gear, spring, adjustment bolt; Described smoothing roll is bolted to the rotating disk below by bearing block and many groups; Described rotating disk is fixed on the slide by positioning core axle; The described casing of angle modulation main drive is arranged on the slide and inside is provided with described spring and adjust bolt; Be provided with described half-ring gear between described slide one side and the described rotating disk; Be arranged with described driving gear on the described reducing motor axle and be meshing with each other with described half-ring gear.
Appropriate location on the rotating disk of fixing smoothing roll, the half-ring gear that a straight-tooth is installed with the angle modulation of satisfying smoothing roll in a big way, at slide a driver pinion device of half-ring gear engagement therewith is installed, only keeping between the casing of this device and the slide has an amount of movement along the line direction between driver pinion center and the half-ring gear center, all limits in remaining direction.And at the other direction of driver pinion and half-ring gear meshing point one group of spring being set, the active force of spring acts on the engagement direction of driver pinion and half-ring gear, guarantees that the engagement process of rotating is the state that keeps no sideshake all the time.Adjust the active force of spring, can realize keeping between driver pinion and the half-ring gear contact force of no sideshake engagement and transmission needs, and can not produce new additional load and increased the driving force of driving gear.Like this in said apparatus, the anglec of rotation that can remain the smoothing roll half-ring gear that driving gear drives in the process of adjusting angle with by and the angular transducer institute feedback data of pinion connection between, deviation can not appear.
