The specific embodiment
Preferred embodiment is described in detail to the utility model below in conjunction with accompanying drawing, thereby so that the advantage of utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
See also Fig. 1, Fig. 2 and Fig. 3, the utility model embodiment comprises:
A kind of eccentric wheel type Quick fastening vice, this eccentric wheel type Quick fastening vice comprises the fixedly vice body 2 that is installed on the base 1, and movable vice body 5 and eccentric wheel apparatus 11 fixedly are installed on the vice body 2; The described upper plane of base 1 that also comprises is provided with positioning cylinder 10, and positioning cylinder 10 cooperates with the fixing hole of vice body 2 bottoms, and fixedly vice body 2 base plane are abutted against the upper plane in base 1, and fixedly vice body 2 both sides are provided with set bolt 9; Fixedly also be provided with on the two sides of vice body 2 level to emboss pit, movable vice body 5 fixedly is installed on the vice body 2, the emboss pit of movable vice body 5 matches with the fixing emboss pit of vice body 2; Described fixing vice body 2 and the movable vice body 5 of also comprising is provided with the jaw 3 of upward opening, is equipped with jaw plate 4 on the vice jaw surface that fixedly vice body 2 and movable vice body 5 are corresponding; Fixedly the right positions of installation activity vice body 5 also is equipped with eccentric wheel apparatus 11 on the vice body 2, and eccentric wheel apparatus 11 is against on the movable vice body 5.
The upper plane of described fixedly vice body 2 also is provided with a plurality of jacks 12, and jack 12 is arranged in line, and is parallel to the fixedly emboss pit of vice body.
Described eccentric wheel apparatus 11 comprises camshaft 6, eccentric wheel handle 7 and eccentric wheel 8, described camshaft 6 lower ends are passed in the jack 12 that is installed on plane on the fixing vice body 2 behind the eccentric wheel 8 and matched in clearance, camshaft 6 is fixedly connected with eccentric wheel 8, but the upper end of camshaft 6 is provided with the eccentric wheel handle 7 that move left and right is regulated; The arc-shaped edges of eccentric wheel 8 is against on the movable vice body 5.
The working method of a kind of eccentric wheel type Quick fastening vice of the utility model is: with reference to figure 4, O 2Be the geometric center of circularly-eccentric sheave, R is its geometric radius, O 1Point is the eccentric centre of gyration, O 2O 1Be eccentric throw.If with O 1Be the center of circle, r is that diameter is drawn circle, just eccentric wheel is divided into 3 parts.Wherein, dotted portion is " base disc ", radius r=R-e.Two parts are two identical arc wedges in addition.When the eccentric wheel wraparound turns center O 1When rotating clockwise, be equivalent to an arc wedge and wedge gradually between " base disc " and the workpiece, thus clamping work pieces.
With reference to figure 3, e is eccentric throw, and R is the eccentric wheel geometric radius, and L is fixing locating hole pitch-row on the vice body; As R+e〉during L, can realize clamping without blind spot; When R+e=L, clamped condition is in extreme position, and be in Dangerous Place this moment, easily skids; When needs clamp certain workpiece, shift onto and the workpiece contact position with the handgrip moving jaw first, then eccentric axle is put into the fixedly lower hole of vice body, when rotating clockwise, be equivalent to an arc wedge and wedge gradually between " base disc " and the workpiece, thus clamping work pieces; Unclamp set bolt 9 and just can 360 ° rotate fixedly vice body 2, select proper operating position, and then the bolt 9 that is locked.
The utility model also has a kind of more excellent embodiment, as shown in Figure 3: require R+e〉2L.When needs clamp certain workpiece, shift onto and the workpiece contact position with the movable vice body of handgrip first, make the datum line on the eccentric wheel vertical with movable vice body, then eccentric axle is put into the locating hole on the fixing vice body, the end that makes the datum line on the eccentric wheel is the shortest apart from S from movable vice body.The hole at eccentric wheel place is only clamped position.Then pull handle and make the eccentric wheel wraparound turn the center to turn clockwise, thus clamping work pieces, and after external force was removed, jaw also was difficult for unclamping.
A kind of eccentric wheel type Quick fastening vice of the utility model can shorten the clamping workpiece required time greatly guaranteeing that enough clamping forces make in the reliable situation of Workpiece clamping, and the occasion that is particularly suitable for frequent blank dimension is used; And simple and compact for structure, handsome in appearance, low cost of manufacture; Be convenient to after the parts depreciation change.
