Description
Technical field
The utility model relates to hold-down mechanism, is specially a kind of mechanical double-way hold-down mechanism.
Background technology
Hold-down mechanism is widely used in process of factory production, for the correct position that obtains behind holding workpiece location.Conventional hold-down mechanism has: spiral hold-down mechanism, wedge hold-down mechanism, eccentric compacting mechanism, lever device etc., the most common with spiral hold-down mechanism in manual hold-down mechanism, with screw shaft, around self axis, rotarily driving nut moves back and forth and compresses or loosen workpiece, also have the motion mode that linkage or other mechanisms convert other to that moves through of nut, reach the object of clamping.
At present, on market, the most common Bidirectional compacting mechanism is automobile hand jack, the connection rod set quadrangularly that it is mainly connected by four head and the tail, tetragonal four angles are hinge, a screw rod passes quadrangle as diagonal, connect two hinges on diagonal, relative motion by screw rod and bight nut changes tetragonal cornerwise length, another cornerwise length is changed, along this diagonal transfer function power, make the angle at these two diagonal angles change jack-up or put down weight.By screw rod and nut, form screw mechanism, one in screw rod, nut and two other angle forms linkage, adds the frame of support helix mechanism, linkage, detent mechanism, can form Bidirectional compacting mechanism.The shortcoming of this mechanism is: 1, only have single screw pair, the direction that the point of transfer function power moves along with nut and moving, is not suitable for the fixing occasion of line of action of force; 2, clamp and the movement velocity loosened slow, efficiency is low; 3, it is intermeshing that the hinge place two connecting rod convex and concave teeths of weight are put on top, and manufacturing cost is high.
Summary of the invention
The problems referred to above that the utility model exists in order to solve current hold-down mechanism, provide a kind of mechanical double-way hold-down mechanism.
The utility model is to adopt following technical scheme to realize:
A mechanical double-way hold-down mechanism, comprises support, in described support, by axle sleeve, supports a screw rod, and one end of screw rod is connected with compression axis by shaft coupling, and described compression axis passes support by axle sleeve and is connected with handle; Left and right two parts of described screw rod are processed with respectively the screw thread of opposite direction, on left and right two parts screw thread of screw rod, be rotary with respectively nut block corresponding to rotation direction, described each nut block is all hinged to one end of two connecting rods inserting with screw rod both sides level, and the other end of described four connecting rods is hinged by hinge between two respectively; Described two hinges are fixedly connected with respectively pressing plate.
During work, handle, for Double-directional rotary compression axis, makes the rotation of compression axis reach screw rod by shaft coupling, and on screw rod, two nut block are rotated in opposite directions by two hinges and converted the pressing plate edge of hinge connection to perpendicular to the rectilinear motion that advances or retreat of screw rod.While clockwise rotating handle, can push workpiece to seal face, while rotating counterclockwise handle, can loosen workpiece.
When two screw pairs are at the uniform velocity adjacent to each other, the pressing plate at hinge place belongs to even deceleration rectilinear motion to the motion of workpiece pressing direction, and the thrust therefore workpiece being applied increases gradually, can save manual force like this.In addition, when two screw pairs are at the uniform velocity adjacent to each other or away from time more fast again than the translational speed of a screw pair, the speed that compresses like this and loosen has also improved nearly one times, and the direction of active force is all the time on the angular bisector of hinge angle, because Design of Screw Thread is with self-locking, can effectively prevent that transportation, vibration from causing loosening.
The utility model is reasonable in design, simple in structure, this hold-down mechanism has adopted brand-new bidirectional screw, helical axis plural serial stage tandem type compressing structure, bidirectional screw mechanism, linkage are combined together, two screw pairs drive two hinges, two hinges are arranged symmetrically with and have realized Bidirectional compacting along the axis of screw pair, realize " generation is many ", without any power supply, source of the gas, only need turning handle gently can realize many workpiece of Bidirectional compacting simultaneously, its compact conformation, volume is little, and compression mode is simple and direct, convenient, can carry out modularization assembling simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1-support, 2-handle, 3-compression axis, 4-nut block, 5-shaft coupling, 6-hinge, 7-connecting rod, 8-pressing plate, 9-screw rod, 10-power transmission shaft, 11-axle sleeve.
The specific embodiment
Below in conjunction with accompanying drawing, specific embodiments of the invention are elaborated.
As shown in Figure 1, a kind of mechanical double-way hold-down mechanism, comprises support 1, in described support 1, by axle sleeve 11, supports a screw rod 9, and one end of screw rod 9 is connected with compression axis 3 by shaft coupling 5, and described compression axis 3 passes support 1 by axle sleeve 11 and is connected with handle 2; Left and right two parts of described screw rod 9 are processed with respectively the screw thread of opposite direction, on left and right two parts screw thread of screw rod 9, be rotary with respectively nut block corresponding to rotation direction 4, described each nut block 4 is all hinged to one end of two connecting rods 7 inserting with screw rod 9 both sides levels, and the other end of described four connecting rods 7 is hinged by hinge 6 between two respectively; Described two hinges 6 are fixedly connected with respectively pressing plate 8.
Four isometric connecting rod head and the tail connections between two, article one, two summits on diagonal replace by two nut block, and through a screw rod, form two screw pairs, form quadric chain with four connecting rods, drive two hinges freely to change the size of angle, swaying of screw rod is converted to the rectilinear motion perpendicular to axle.This mechanism structure is compact, and institute takes up space little.
Two screw pairs can drive two to compress point, the other end at power transmission shaft joins two screw pairs again, by that analogy, while carrying out modularization assemble, the other end of screw rod is connected with power transmission shaft by shaft coupling, for connecting another module, can expand a plurality of compression points, realization, to the compression of multi-work piece more, realizes " generation is many ", compresses a plurality of workpiece simultaneously.
During concrete enforcement, the other end of described screw rod 9 is connected with the power transmission shaft 10 that passes support 1 by shaft coupling 5.Described three axle sleeves 11 are arranged on respectively on three columns of support 1 by screw; Described shaft coupling 11 one end are connected with compression axis 3, and the other end is connected with screw rod 5; Described power transmission shaft 10 is arranged in other two axle sleeves 11, is connected with shaft coupling 5.
