Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of crank-motion structure of the utility model;
The mark implication of accompanying drawing is as follows:
1: crankshaft; 2: crankwheel; 3: slide guide; 4: slide block; 5: first connecting rod; 6: second connecting rod; 7: third connecting rod; 8: vertically connecting rod.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, technical solutions of the utility model are described in further detail, to make those skilled in the art better can understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.
As shown in Figure 1, a kind of crank-motion structure, comprises crankshaft 1, and the end of crankshaft 1 is provided with crankwheel 2, and the center of circle of crankwheel 2 is O, is provided with the slide guide 3 of level below described crankwheel 2, is provided with movable sliding block 4 in described slide guide 3.
One end a of first connecting rod 5 is arranged on crankwheel 2, one end e of third connecting rod 7 is connected with slide block 4 and the other end is connected with the other end c of first connecting rod 5, one end d of second connecting rod 6 is arranged on third connecting rod 7 and the other end b is arranged on immediately below crankwheel 2 center of circle O, preferably, the b end of described second connecting rod 6 is fixed on slide guide 3.The c of described first connecting rod 5 holds the connecting rod be provided with for supporting workpiece.
Preferably, one end d of second connecting rod 6 is arranged on the neutral position of third connecting rod 7, and the distance between dc equals the distance between db.
Preferably, the c of described first connecting rod 5 holds the vertical connecting rod 8 be provided with for supporting workpiece, and the bottom f of vertical connecting rod 8 can be used for connecting workpiece.
Preferably, the length of first connecting rod 5 is greater than the length of third connecting rod 7, generally speaking, the length of first connecting rod 5 be the length of third connecting rod 7 1.2-1.8 doubly between, the motion of workpiece is more succinct.
Slide block 4 can slide in the horizontal direction in slide guide 3, and when crankwheel 2 rotates along with crankshaft 1, drive workpiece to do vertical motion, structure is simple, and cost is low, easy to use.
These are only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in the technical field that other are relevant, be all in like manner included in scope of patent protection of the present utility model.
