Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
The assembling structural representation of the roll gap adjustment device that Fig. 1 provides for this utility model embodiment;
Fig. 2 is this utility model embodiment mounting seat provided and the assembling structural representation regulating axle.
Wherein, 1 is mounting seat, and 2 for regulating axle, and 3 is adjusting screw, and 4 is spring holder.
Detailed description of the invention
The utility model 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 this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments. Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to the assembling structural representation of the roll gap adjustment device that Fig. 1 and Fig. 2, Fig. 1 provide for this utility model embodiment; Fig. 2 is this utility model embodiment mounting seat provided and the assembling structural representation regulating axle.
The roll gap adjustment device that this utility model embodiment provides, its core improvement is in that, including mounting seat 1, regulates axle 2 and adjusting screw 3, and its structure is referred to shown in Fig. 1;
Wherein, mounting seat 1, for being fixed on the casing of milling train, specifically can pass through screw mode;
Regulate axle 2 and be rotatably provided in mounting seat 1;
The end of the end and adjusting screw 3 that regulate axle 2 is connected by spline fitted. When roll gap is adjusted by needs, it is only necessary to rotate the exposed junction regulating axle 2, thus driving adjusting screw 3 to rotate; Adjusting screw 3 coordinates with other roll-separating mechanisms (such as eccentric bushing) in roller case afterwards, and its construction features is identical with prior art with operation principle, does not repeat them here.
From above-mentioned technical scheme it can be seen that the roll-separating mechanism of this utility model embodiment offer, it is regulated axle 2 and is connected with adjusting screw 3 by spline, compare the engagement of original gear, reduce drive gap, improve roll gap regulation precision such that it is able to improve product quality.
As preferably, the end regulating axle 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 connect reliably. It is, of course, also possible to by both interior external splines set-up modes in turn.
In order to optimize above-mentioned technical scheme further, it is provided with axial positioning structure between mounting seat 1 and adjustment axle 2, and this axial positioning structure can be fixed on, by regulating axle 2, the axial location that at least two is different, the distance between the two axial location is not less than the axial dimension of spline. When loading and unloading roller case, making adjustment axle 2 switch between two different positions by above-mentioned axial positioning structure, correspondence makes spline depart from and engages respectively, it is prevented that regulates axle 2 and loosens, it may be achieved rapid-assembling/disassembling.
In the specific embodiment that this programme provides, axial positioning structure includes the spring holder 4 being arranged in mounting seat 1, position scrobicular ring with being opened at least two regulated on axle 2 periphery wall, and the distance between the scrobicular ring of the two location is not less than the axial dimension of spline. Its structure is referred to shown in Fig. 1, when loading and unloading roller case, is axially moveable adjustment axle 2, and the ball in spring holder 4 snaps in the scrobicular ring of location, it is prevented that regulates axle and loosens.
This utility model embodiment additionally provides a kind of milling train, and including casing and the roll gap adjustment device being disposed thereon, its core improvement is in that, roll gap adjustment device is above-mentioned roll gap adjustment device.
In sum, this utility model embodiment provides a kind of roll gap adjustment device, is arranged on the casing of milling train, including regulating axle and spring holder, being provided with locating ring on described adjustment axle, one end is provided with internal spline, matches even with the external splines regulated on screw mandrel on roller case. When loading and unloading roller case, mobile adjustment axle, make spline depart from and engage, the ball in spring holder snaps in locating ring, it is prevented that regulates axle and loosens. This is simple and reliable for structure, is connected by spline, it may be achieved rapid-assembling/disassembling, and reduces drive gap, improves roll gap regulation precision. This utility model embodiment additionally provides a kind of milling train applying above-mentioned roll gap adjustment device, is connected with roller case roll-separating mechanism by spline, compares the original gear engagement of gear, and gap is less, and precision is higher.
