Abstract
The invention relates to a magnetic driving cam crankshaft mechanism. The magnetic driving cam crankshaft mechanism is characterized in that a driving wheel is fixed on a driving shaft, a driving wheel arc-shaped prismatic magnet and a driving wheel arc-shaped magnetic ring are arranged on the outer edge of the driving wheel, a protective cover is installed outside the driving shaft and the driving wheel, two telescopic rod sleeves are fixed at the position on the protective cover corresponding to the driving wheel, the bottom ends of telescopic rods are provided with two telescopic rod magnets, and the driving wheel arc-shaped magnetic ring and the driving wheel arc-shaped prismatic magnet are outward in a homopolar mode and opposite to the telescopic rod magnets in the homopolar mode. The telescopic rods are hinged to a connecting rod, and the connecting rod is connected with a cam. The magnetic driving cam crankshaft mechanism has the advantages that the driving wheel is not contacted with a driven part, friction and noise are not produced in the movement process, the service life of parts are prolonged, the cost is reduced, and the mechanism is simple in structure and accurate in control and achieves cam crankshaft transmission from visible to invisible.
Description
Technical field
The present invention relates to a kind of cam crank mechanism, be specially a kind of magnetic force cam crank that adopts the magnetic repulsion drive link to make the Cam reciprocating motion.
Background technology
From present technology, cam is a member with curved profile or groove, and Main Function is to make follower lever finish the motion of various complexity according to job requirement, comprises rectilinear motion, swing, movement at the uniform velocity and variable-speed motion.Be divided three classes according to the unusual of its outward appearance and purposes: disc cam, translating cam, cylindrical cam.
The advantage of these cam mechanisms is only to need the suitable cam contour of design, just can make driven member obtain arbitrarily desired movement track, and simple in structure, compact, easy to use, therefore in automatic machine tool, light industry and machinery, textile machine, printing machinery, food machinery, package packing machine and electromechanical integrated product, be used widely.
But at present structure and the operational mode of cam have determined that it has a lot of drawbacks, and be easy to wear as contact for point or line between cam and driven member, should be used for the little occasion of driving torque; The cam contour required precision is higher, needs to process with Digit Control Machine Tool; The stroke of driven member can not be excessive, otherwise can make cam become heavy.Therefore need a kind of cam crank mechanism little, that power consumption is low, efficient is high of wearing and tearing badly.
Summary of the invention
The purpose of this invention is to provide a kind of magnetic drive cam crank mechanism, namely adopt magnetic force to make connecting axle with in the situation that driving wheel contacts not produce reciprocating motion, and then its friction is reduced, reduce noise, save the parts cost.
The object of the present invention is achieved like this: fix a driving wheel on the driving shaft, be provided with a driving wheel arc rib shape magnet and a driving wheel arc magnet ring on the driving wheel outer rim, the outer protective cover of installing of driving shaft and driving wheel, two expansion link covers are fixed in the position of corresponding driving wheel on the protective cover, there are two expansion link magnet the expansion link bottom, and driving wheel arc magnet ring is outside and relative with expansion link magnet homopolarity with driving wheel arc rib shape magnet homopolarity; The expansion link articulated linkage, connecting rod connects cam.
Purpose of the present invention can also realize like this: the magnetic force of driving wheel arc magnet ring is less than the magnetic force of driving wheel arc rib shape magnet.
Driving wheel arc rib shape magnet and a driving wheel arc magnet ring are sealing and encircle shape, are arranged on the driving wheel outer rim.
The beneficial effect that the present invention reaches is: directly produces contact between driving wheel and the driven member, thereby makes in the process of its motion without friction, and noiselessness, parts increase useful life, reduce cost; Simple in structure, control precisely; Realized the transmission of cam crank from tangible to invisible.

Embodiment
The parts title is as follows shown in each drawing reference numeral:
Driving shaft 1, driving wheel 2, driving wheel arc rib shape magnet 3, driving wheel arc magnet ring 4, protective cover 5, expansion link cover 6, expansion link magnet 7, expansion link 8, connecting rod 9, cam 10.
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of magnetic drive cam crank mechanism, it is characterized in that: fix a driving wheel 2 on the driving shaft 1, be provided with a driving wheel arc rib shape magnet 3 and a driving wheel arc magnet ring 4 on driving wheel 2 outer rims, driving shaft 1 and driving wheel 2 outer installation one protective covers 5, two expansion link covers 6 are fixed in the position of corresponding driving wheel 2 on the protective cover 5, there are two expansion link magnet 7 expansion link 8 bottoms, and driving wheel arc magnet ring 4 is outside and relative with expansion link magnet 7 homopolarities with driving wheel arc rib shape magnet 3 homopolarities; Expansion link 8 articulated linkage 9, connecting rod 9 connects cam 10.
The magnetic force of driving wheel arc magnet ring 4 is less than the magnetic force of driving wheel arc rib shape magnet 3.
Driving wheel arc rib shape magnet 3 and a driving wheel arc magnet ring 4 are sealing and encircle shape, are arranged on driving wheel 2 outer rims.
The course of work: driving shaft rotates and drives driving wheel, driving wheel arc rib shape magnet on the driving wheel, driving wheel arc magnet ring crankmotion, when the corresponding expansion link of driving wheel arc rib shape magnet, because driving wheel arc rib shape magnet is relative with expansion link magnet homopolarity, under powerful magnetic repulsion effect, the expansion link drivening rod is away from driving wheel, when the corresponding expansion link magnet of driving wheel arc magnet ring, because magnetic repulsion is less, expansion link drives connecting axle near driving wheel, under expansion link drives, the connecting rod reciprocally swinging, because connecting rod two ends difference hinge cam and expansion link, thereby the band moving cam moves along certain track, because camshaft links to each other with bent axle, and then promote the bent axle rotation.
