As further improvement, described locking stud is provided with interior hexagonal blind hole away from one end of described worm screw.
As further improvement, in described tapped hole, be also provided with loosing-preventing double-screw bolt.
As further improvement, described disk is provided with a platform, and described platform is positioned at one end that described tapped hole deviates from described worm screw mounting hole.
After have employed technique scheme, the beneficial effects of the utility model are: because eccentric wheel eccentricity regulator comprises disk, on described disk, eccentric rotary is provided with a worm gear, on described worm gear, bias is installed with a circular shaft, described disk is provided with worm screw mounting hole, is rotatablely equipped with the worm screw suitable with described worm gear in described worm screw mounting hole; Described disk is also provided with locking apparatus, thus when eccentric adjustment distance, drives worm gear wheel by rotary worm, thus circular shaft on worm gear is rotated simultaneously, and then realize the change of throw of eccentric, after throw of eccentric has regulated, ensure that worm screw can not shake at work by locking apparatus; Simultaneously because worm and gear has auto-lock function, during circular shaft work, worm screw can not rotate.The utility model regulates by adopting the throw of eccentric of worm and gear to circular shaft, structure is simple, the auto-lock function of worm and gear simultaneously, can effectively guarantee throw of eccentric can not change at work, install and regulate easily, manufacturing cost is low, meets the demand that people accurately regulate easily to throw of eccentric.
Because described locking apparatus comprises the tapped hole be located on described disk, locking stud is installed in described tapped hole, described worm screw is provided with annular groove, described locking stud leans near the end of described worm screw and described annular groove, thus by screwing locking stud, can effectively prevent worm screw from operationally shaking, not only structure be simple, and reliably.
Due to described locking stud devising interior hexagonal blind hole, thus be convenient to force when rotation lock stud.
Owing to being also provided with loosing-preventing double-screw bolt in described tapped hole, effectively avoiding locking stud to loosen, ensure that worm screw operationally can not shake further.
Due to described disk devising platform, the surface that can overcome disk is the defect that arc surface is not easily holed, thus is convenient to the processing of tapped hole.

Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As Fig. 1 and Fig. 2 jointly shown in, a kind of eccentric wheel eccentricity regulator, comprise disk 1, on disk 1, eccentric rotary is provided with a worm gear 2, on worm gear 2, bias is installed with a circular shaft 3, disk 1 is provided with worm screw mounting hole 11, and the axis of worm screw mounting hole 11 is consistent with a tangent direction of worm gear 2, is rotatablely equipped with the worm screw 4 suitable with worm gear 2 in worm screw mounting hole 11; Disk 1 is also provided with the locking apparatus 5 for preventing worm screw 4 from rocking.
Above-mentioned disk 1 and worm gear 2 form eccentric mechanism, and in the present embodiment, the center of worm gear 2 and disk 1 center bias are 0.5e, and circular shaft 3 center and worm gear 2 center bias are also 0.5e, and therefore, circular shaft 3 is e with the maximum eccentric of disk 1.By rotary worm 4, the electrodeless adjustment of throw of eccentric between 0-e of circular shaft 3 opposed discs 1 can be realized.
Above-mentioned locking apparatus 5 comprises the tapped hole 12 be located on disk 1, the axis of tapped hole 12 and the axis of worm screw mounting hole 11 perpendicular, be provided with locking stud 51 in tapped hole 12, worm screw 4 is provided with annular groove 41, and locking stud 51 leans near the end of worm screw 4 and annular groove 41.By screwing locking stud 51, can effectively prevent worm screw 4 from operationally shaking, not only structure is simple, and reliably.
For the ease of rotation lock stud 51, the one end away from worm screw 4 on locking stud 51 is provided with interior hexagonal blind hole 511, thus is convenient to force.
Also be provided with loosing-preventing double-screw bolt 52 in tapped hole 12, effectively avoid locking stud 51 to loosen, ensure that worm screw 4 operationally can not shake further.Certainly, for the ease of rotating loosing-preventing double-screw bolt 52, an end of loosing-preventing double-screw bolt 52 is also provided with interior hexagonal blind hole 521.
Disk 1 is provided with a platform 13, and platform 13 is positioned at one end that tapped hole 12 deviates from worm screw mounting hole 11.The surface that can overcome disk 1 is the defect that arc surface is not easily holed, thus is convenient to the processing of tapped hole 12.
Its working principle is as follows:
When eccentric adjustment distance, drive worm gear 2 to rotate by rotary worm 4, thus circular shaft 3 on worm gear 2 is rotated simultaneously, and then realize the electrodeless adjustment of throw of eccentric between 0-e of circular shaft 3 opposed discs 1, substantially increase degree of regulation; After throw of eccentric has regulated, ensure that worm screw 4 can not shake at work by locking apparatus 5; Simultaneously because worm and gear has auto-lock function, when circular shaft 3 works, worm screw 4 can not rotate.
The utility model regulates by adopting the throw of eccentric of worm and gear to circular shaft 3, structure is simple, the auto-lock function of worm and gear simultaneously, can effectively guarantee throw of eccentric can not change at work, install and regulate easily, manufacturing cost is low, meets the demand that people accurately regulate easily to throw of eccentric.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
