The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that the advantage of invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, Fig. 2 and Fig. 3, the embodiment of the invention comprises:
The quick grip vice of a kind of eccentric wheel type, the quick grip vice of this eccentric wheel type 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 said last 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 last 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; Said 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 last plane of said 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.
Said eccentric wheel apparatus 11 comprises camshaft 6, eccentric wheel handle 7 and eccentric wheel 8; Said 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 circular arc limit of eccentric wheel 8 is against on the movable vice body 5.
The working method of the quick grip vice of a kind of eccentric wheel type of the present invention 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 is divided into 3 parts to eccentric wheel.Wherein, dotted portion is " a basic circle dish ", radius r=R-e.Two parts are two identical arc wedges in addition.When center O is changeed in the eccentric wheel wraparound 1When clockwise direction rotates, be equivalent to an arc wedge and wedge gradually between " basic circle dish " and the workpiece, thus clamping work pieces.
With reference to figure 3, e is an eccentric throw, and R is the eccentric wheel geometric radius, and L is a fixation clamps locating hole pitch-row on one's body; As R+e>during L, can realize not having blind spot and clamp; When R+e=L, clamped condition is in extreme position, is in dangerous place this moment, skids easily; When needs clamp certain workpiece; Shift onto and the workpiece contact position with the handgrip moving jaw earlier, then eccentric axle is put into the fixedly following hole of vice body, when clockwise direction rotates; Be equivalent to an arc wedge and wedge gradually between " basic circle dish " and the workpiece, thus clamping work pieces; Unclamping set bolt 9 just can 360 ° of rotational fixation vice body 2, selects proper operating position, and then the bolt 9 that is locked.
The present invention also has a kind of more excellent embodiment, and is as shown in Figure 3: as to require R+e>2L.When needs clamp certain workpiece; Shift onto and the workpiece contact position with the movable vice body of handgrip earlier; Make the datum line on the eccentric wheel vertical, then eccentric axle is put into fixation clamps locating hole on one's body, make the end of the datum line on the eccentric wheel leave the shortest of movable vice body apart from S with movable vice body.The hole at eccentric wheel place is only clamped position.Pull handle then eccentric wheel wraparound commentaries on classics center is turned clockwise, thus clamping work pieces, and after external force was removed, jaw also was difficult for unclamping.
The quick grip vice of a kind of eccentric wheel type of the present invention can shorten the clamping workpiece required time greatly guaranteeing that enough clamping forces make under the workpiece positioning and reliable clamping situation, and the occasion that is particularly suitable for frequent change 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.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
