Detailed description of the invention
The invention discloses a kind of milling train and roll-separating mechanism thereof, compared with existing gear engagement structure, gap is less, and precision is higher.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1 and Fig. 2, the assembly structure schematic diagram of the roll gap adjustment device that Fig. 1 provides for the embodiment of the present invention; The assembly structure schematic diagram of the mount pad that Fig. 2 provides for the embodiment of the present invention and regulating shaft.
The roll gap adjustment device that the embodiment of the present invention provides, its core improvement is, comprises mount pad 1, regulating shaft 2 and adjusting screw 3, and its structure can with reference to shown in Fig. 1;
Wherein, mount pad 1, for being fixed on the casing of milling train, specifically can pass through screw mode;
Regulating shaft 2 is rotatably arranged in mount pad 1;
The end of regulating shaft 2 is connected by spline fitted with the end of adjusting screw 3.When needs regulate roll gap, only need the exposed junction rotating regulating shaft 2, thus drive adjusting screw 3 to rotate; Adjusting screw 3 coordinates with other roll-separating mechanisms (such as eccentric bushing) in roller case afterwards, and its design feature is identical with prior art with operation principle, does not repeat them here.
As can be seen from above-mentioned technical scheme, the roll-separating mechanism that the embodiment of the present invention provides, its regulating shaft 2 is connected with adjusting screw 3 by spline, compare original gears meshing, reduce drive gap, improve roll gap regulation precision, thus can improve the quality of products.
As preferably, the end of regulating shaft 2 is provided with internal spline, and the end of adjusting screw 3 is provided with the external splines coordinated with internal spline, to realize stable and to be connected reliably.Certainly, can also by external splines set-up mode in both conversely.
In order to optimize above-mentioned technical scheme further, axial positioning structure is provided with between mount pad 1 and regulating shaft 2, and regulating shaft 2 can be fixed at least two different axial locations by this axial positioning structure, the distance between these two axial locations is not less than the axial dimension of spline.When loading and unloading roller case, by above-mentioned axial positioning structure, regulating shaft 2 is switched between two different positions, correspondence makes spline depart from and engages respectively, prevents regulating shaft 2 from loosening, can realize rapid-assembling/disassembling.
