Abstract
The invention discloses a conversion mechanism for converting permanent magnetic force rotary motion into linear reciprocating motion, which utilizes the interaction of N, S poles of permanent magnetic poles which are arranged alternately at equal division positions on a disc and other discs which are arranged identically, so that one or more discs do rotary motion and simultaneously push the disc called a movable disc to do reciprocating linear motion, thereby realizing the conversion of motion modes. The mechanism has simple and compact structure and self-locking property. Besides being used as a transmission mechanism, the locking device can also be used for locking a fixing clamp.
Description
The present invention is a kind of conversion mechanism from permanent-magnet rotation motion to linear one.Utilize the permanent magnet principle of " same sex is repelled each other, there is a natural attraction between the sexes ", be arranged alternately N, S permanent magnetism magnetic pole on the surface of garden dish along garden Zhou Fangxiang position of halving, number of magnetic poles is N(N=2,4,6 ...).When two same garden dishes are close, when two corresponding dish magnetic pole magnetic are identical, produce repulsion, generation suction when opposite.Limiting a garden dish can not rotate, be referred to as Moving plate, limiting another garden dish can not do rectilinear motion and be referred to as rotating disk, during dial rotation permanent magnetism magnetic pole will with Moving plate on permanent magnetism magnetic pole interact, it is reciprocating that moving Moving plate is tried hard to recommend in generation " suction, row ", realizes the rotation motion straight reciprocating motion.
The objective of the invention is to seek a kind of novel transmission mechanism, replace present crank, slip pipe, crankshaft-link rod and the cam drive that generally uses, improve the efficient in the rotation motion to linear process, the useful life of parts, make mechanism driving steady, working space dwindles and has a self-locking performance.Except that making transmission mechanism, also can be used as holding clamp.
In the accompanying drawing: Fig. 1 is the disk schematic diagram
Fig. 2 is a double plate transmission schematic diagram
Fig. 3 is three dish transmission schematic diagrames
Among the figure: 1 is the magnetic rotating disk; 2 is the magnetic Moving plate; 3 is the magnetic pole on the disk; 4 are rotating shaft; 5 reciprocal axles; 6,9 is the magnetic rotating disk; 7 is the center tubular axis; 8 is Moving plate; 10 supporting sleeves; 11 reciprocal axles; 12 connect backup plate; 13 rotating shafts.
The course of work of this mechanism is such, and is identical with the polarity of Moving plate for the polarity of double plate mechanism rotating disk, and the magnetic force moving Moving plate is away from rotating disk, 360 °/N(N=2 of dial rotation, 4,6 ...) after, the polarity of rotating disk magnetic pole is opposite with Moving plate, and suction sucks back Moving plate. So analogize, along with the rotation of rotating disk, Moving plate is produced " inhale, arrange " effect, drive Moving plate and move reciprocatingly, moving Dish can drive plunger, connecting rod or other parts, realizes linear reciprocating motion.
The double plate transmission, each constantly only only is subjected to " scold or inhale " power Moving plate, because magnetic force is inversely proportional to square distance between Moving plate and the rotating disk, suffered active force is unbalanced, operating distance is lacked.After adopting three dishes or polydisc, can overcome above-mentioned shortcoming.Fig. 3 is the schematic diagram of three dish rotating mechanisms, similar to double disk structure, increase the rotating disk that a pole polarity differs 360 °/N, and two rotating disks are combined as a whole, Moving plate is placed in the middle of two rotating disks, and any moment of Moving plate all is subjected to the active force from the action direction unanimity of left and right sides Moving plate, during away from the repulsion dish near the suction dish, reducing of repulsion can be by the increase compensation of suction, and vice versa.
