In figure, 1, cylindrical cam; 2, the first fork; 3, the first supporting seat; 4, the first oscillating bearing; 5, connecting rod; 6, planar trenches cam; 7, the second fork; 8, the second supporting seat; 9, output; 10, second joint bearing; 11, axle; 12, sprocket wheel; 13, bearing seat; 14, fixed block.
Detailed description of the invention
The technical solution of the utility model is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of reciprocating mechanism, comprise cylindrical cam mechanism and plane grooved cam mechanism, cylindrical cam mechanism comprises cylindrical cam 1, first roller and the first fork 2, first fork 2 one end is rotated around the first supporting seat 3, the other end connects connecting rod 5 by the first oscillating bearing 4, first roller coordinates drive first fork 2 to swing with cylindrical cam 1, planar trenches cam mechanism comprises planar trenches cam 6, second roller and the second fork 7, second fork 7 one end is rotated around the second supporting seat 8, the other end connects output 9, second roller coordinates drive second fork 7 to swing with planar trenches cam 6, connecting rod 5 connects output 9 by second joint bearing 10, the reciprocating mechanism that the present embodiment proposes realizes the crank motion of output 9 by the cylindrical cam mechanism and plane grooved cam mechanism arranging parallel connection, replace and adopt spring that fork is held the structure with cam engagement in the past, solve fork tripping problems during cam high speed rotating, thus enhance productivity.
In the present embodiment, cylindrical cam 1 and planar trenches cam 6 are around same axle 11 rotating in same direction, rationally distributed, make mechanism structure compact, conserve space and cost, those skilled in the art as required, can select the mode that cylindrical cam 1 and plane grooved cam 6 rotate around disalignment.
In the present embodiment, axle 11 is connected motor by sprocket wheel 12 with chain, and those skilled in the art also can adopt other driver trains.
In the present embodiment, axle 11 two ends, by bearing adapter shaft bearing 13, make the rotation of the cam on axle 11 reliable, stable.
In the present embodiment, output 9 and the second fork 7 are connected through the hinge, and wherein output 9 is rod-like structure, and its one end be connected with the second fork 7 has U-shaped opening, the end of the second fork 7 is stretched in U-shaped opening, and the swing of the second fork 7 drives the up-and-down movement of output 9.
In the present embodiment, adapt to the structure of output 9, output 9 is fixed with fixed block 14, fixed block 14 is connected by second joint bearing 10 with connecting rod 5.
This reciprocating mechanism that the present embodiment proposes, output 9 is driven by cylindrical cam mechanism and the parallel connection of plane grooved cam mechanism, because the motion of the first fork 2 and the second fork 7 is not on the same face, connecting rod 5 two ends are connected the first fork 2 and fixed block 14 respectively by the first oscillating bearing 4 with second joint bearing 10, both prevent the interference of moving between part, be convenient to again assembling.
Obviously, above-described embodiment of the present utility model is only to clearly demonstrate the utility model example, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., within the protection domain that all should be included in the utility model claim.
