Description
Technical field
the utility model belongs to a kind of mechanical cam, is specifically related to a kind of Combined cam carrying out compound movement.
Background technique
cam mechanism is generally by cam, the higher pair mechanism of driven member and frame three component compositions, only need design suitable cam profile, just driven member can be made to obtain arbitrary desired movement, and structure is simple, compact, design convenient, is therefore used widely in automatic machine tool, light industry and machinery, textile manufacturing machine, printing machinery, food machinery, package packing machine and electromechanical integrated product.The characteristics of motion of such as air valve stem defines the contours profiles of cam.When the cam profile of radius vector change contacts with the flat of air valve stem, air valve stem produces to-and-fro motion; And when the circular arc segment profile being the center of circle with cam gyration center contacts with air valve stem, air valve stem is by transfixion.Therefore, along with the continuous rotation of cam, air valve stem can obtain interval, by expection rule motion.But single straight line motion or circular movement can only be obtained, the compound movement demand in machinery production is not yet solved.
Model utility content
the purpose of this utility model is to solve the contours profiles that prior art adopts certain cam, along with the continuous rotation of this cam, motion that air valve stem obtains interval, that press expection rule, but be only limitted to obtain single straight line motion or circular movement, Applicable scope is narrower, cannot meet Production requirement.
in order to solve the problems of the technologies described above, the utility model provides a kind of Combined cam carrying out compound movement, comprise active sliding block, connecting rod, chute, guide vane, bearing, described active sliding block connects the piston rod of cylinder, and active sliding block is hinged with the connecting rod of a L shape, the minor face end of connecting rod is hinged with a roller; Described bearing offers parallelogram chute, parallelogram chute is made up of two long limits and two vertical minor faces, the long limit of chute is provided with transition slot, and the transition slot on two long limits is diagonal angle, and transition slot stretches out in the horizontal direction, the long limit of chute and connecting rod level, described roller is stuck in chute, and roller housing is on roller shaft, and output shaft is coaxial with roller shaft, the transition slot of chute and the jointing place of minor face are provided with guide vane, and there is torsion spring guide vane hinged place.
the utility model adopts parallelogram chute, and on the long limit of chute, be provided with transition slot, when the piston rod drivening rod of cylinder can be allowed to move, straight line motion is done along chute, simultaneously, the roller of connecting rod low side slides into transition slot place, the circular movement that to do with transition slot summit be the center of circle, thus connecting rod does the compound movement that straight line motion and circular movement combine, the utility model adopts guide vane to be linked at the jointing place of transition slot and chute minor face, there is torsion spring guide vane hinged place simultaneously, mainly at the guide vane place of roller-coaster to close bearing bottom, because impetus, guide vane moves downward, roller slides in transition slot, because torsion spring makes guide vane reset, roller moves due to Action of Gravity Field on the right side of chute, when roller moves upward, promotion guide vane moves upward, roller slides in transition slot automatically, because torsion spring makes guide vane reset, roller moves due to Action of Gravity Field on the left of chute, due to the effect of guide vane, make roller can pass through dead angle smoothly, the motion in parallelogram chute can be completed like this.
make improvements for such scheme, active sliding block is stuck in dovetail groove, and dovetail groove is provided with inclined notch, and dovetail groove bottom is connected with bearing, in order to prevent active sliding block from coming off in the process doing compound movement, affects machine process and effect.
make improvements for such scheme, roller will pass through two transition slots, and horizontal first motion track is greater than the long limit of chute itself, and length of connecting rod edge lengths is greater than the length on the long limit of parallelogram chute, could can complete compound movement.
make improvements for such scheme, active sliding block, L shape connecting rod, chute in a vertical plane, in order to accomplish linear motion.
Accompanying drawing explanation
below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
fig. 1 is plan view of the present utility model.
mark in above-mentioned figure is: connecting rod 1, chute 2, the first guide vane 3, second guide vane 4, active sliding block 5, dovetail groove 6, output shaft 7, roller 8, roller shaft 9, torsion spring 10, piston rod 11, bearing 12, transition slot 13.
Embodiment
as shown in Figure 1, the utility model provides a kind of Combined cam carrying out compound movement, comprise active sliding block 5, connecting rod 1, chute 2, the first guide vane 3, second guide vane 4, bearing 12, active sliding block 5 is rectangle, and lower end has inclination breach, and dovetail groove 6 is provided with corresponding inclined notch, active sliding block is stuck in dovetail groove, dovetail groove 6 bottom is connected with bearing 12, and rectangle bearing is in vertically placing, and active sliding block 5 connects the piston rod 11 of cylinder, active sliding block 5 is hinged with the connecting rod 1 of a L shape, the minor face end of connecting rod is hinged with a roller 8, the vertical plane of bearing 12 offers parallelogram chute 2, parallelogram chute 2 is made up of two long limits and two vertical minor faces, the long limit of chute is provided with transition slot 13, fillet is made at the summit place of transition slot 13, two other point of intersection is obtuse angle, transition slot on two long limits is diagonal angle, transition slot stretches out in the horizontal direction, the long limit of chute 2 and connecting rod 1 level, roller 8 will pass through two transition slots 13, horizontal first motion track is greater than the long limit of chute itself, the long edge lengths of connecting rod 1 is greater than the length on the long limit of parallelogram chute, roller 8 is stuck in chute 2, roller 8 is enclosed within roller shaft 9, output shaft 7 is coaxial with roller shaft 9, the transition slot 13 of chute and the jointing place of minor face are provided with the first guide vane 3 and the second guide vane 4, there is torsion spring 10 guide vane hinged place, active sliding block 5, L shape connecting rod 1, chute 2 is in a vertical plane.
preferably, the piston rod 11 of cylinder promotes active sliding block 5, the motion that active sliding block is reciprocal back and forth in dovetail groove 6, active sliding block 5 drivening rod 1 moves, the roller 8 of connecting rod is stuck in parallelogram chute 2, and on the long limit of chute, be provided with transition slot 13, connecting rod 1 does straight line motion along chute 2, moving direction is counterclockwise movement, simultaneously, the roller 8 of connecting rod low side slides into transition slot 13 place, the circular movement that to do with transition slot summit be the center of circle, thus connecting rod 1 does the compound movement that straight line motion and circular movement combine, the dead point being able to by chute 2 for making reciprocating connecting rod 1, can at dead point place installing guide vane 3 and 4, utilize the method for installing guide vane, design novel unique guide cam, guide vane is linked at the jointing place of transition slot 13 and chute 2 minor face, there is torsion spring 10 guide vane hinged place simultaneously, mainly at first guide vane 3 place of roller-coaster to close bearing bottom, because impetus, first guide vane 3 moves downward, roller 8 slides in transition slot 13, because torsion spring 10 makes the first guide vane 3 reset, roller 8 moves due to Action of Gravity Field on the right side of chute 2, when roller 8 moves upward, promote the second guide vane 4 to move upward, roller 8 slides in transition slot 13 automatically, because torsion spring 10 makes the second guide vane 4 reset, roller 8 moves due to Action of Gravity Field on the left of chute 2.
