Background technique
The Geneva mechanism ubiquity poor stability used in prior art, rotating accuracy requires the problems such as high, when the transmission of power based on point cantact, very unfavorable to the transmission of power like this.
The utility model patent being CN203809631U as notification number discloses a kind of Geneva mechanism, comprise driver plate and sheave, described driver plate is connected with transmission device, described driver plate is provided with thumb wheel and Locking arc, described sheave is provided with the gear teeth of decile, the described gear teeth are provided with the cambered surface of mating with described Locking arc, described adjacent two-wheeled between cog has allocating slot, described allocating slot coordinates with described thumb wheel, described Locking arc has open section, the center of circle of described thumb wheel is formed on the angular bisector of angle at described open section and the described thumb wheel center of circle, described thumb wheel is about to the moment entering allocating slot, the part that described Locking arc exceeds driver plate and thumb wheel center of circle connecting line is locking section, there is on the downside of the end that it is characterized in that the described gear teeth step of inside indentation, described step and gear teeth body form a described Locking arc of confession and pass through space, the end face of described sheave is higher than the end face of Locking arc, and the end face of described Locking arc is concordant with the end face of described locking section, when described Locking arc does not leave the cambered surface of the gear teeth, described thumb wheel has entered described allocating slot.This structure of the present utility model, after the end of gear arranges step, can lengthen the length of Locking arc, farthest increases the area of contact of Locking arc and sheave gear teeth cambered surface, avoids sheave to swing, make thumb wheel enter allocating slot accurately.But this device exists power equally transmits unstable problem.
And for example notification number is the second hand machinery science popularization device that the utility model patent of CN204066530U discloses a kind of Geneva mechanism, comprising: base plate, upper saw pulley, sheave, axial screw A, axial screw B, straight pin and rotatory handling; Described upper saw pulley, comprising: cutaway disk and chassis, and cutaway disk is placed on chassis, becomes one structure; Described cutaway disk is provided with rotatory handling and Locking arc, and chassis is provided with straight pin; Described sheave is first-class is arranged with the gear teeth, the gear teeth are provided with cambered surface, the Locking arc of cambered surface and cutaway disk matches, rotation slot is provided with between adjacent two gear teeth, described rotation slot and straight pin match, described Locking arc is provided with opening, and the angle center line between described opening is overlapping with the center of circle of straight pin; Described upper saw pulley is fixed on base plate by axial screw A, and described sheave is fixed on base plate by axial screw B; This device has that cost is low, operation requirements is simple, Security is high and can make the advantages such as the transmission principle of power in the person's of receiving instruction profound understanding mechanical transmission directly perceived.But this patent exists power equally transmits unstable problem.
Model utility content
There is the problem of the transmission instability of power for overcoming Geneva mechanism in prior art, the utility model provides a kind of Geneva mechanism, and concrete technological scheme is as follows:
A kind of Geneva mechanism, comprise driving crank, sheave body, described driving crank rotational axis is parallel with described sheave body rotational axis, described driving crank comprises pulling axis, lock plate and finger, described sheave body outer is evenly distributed with the elongated slot agreed with mutually with described finger, is provided with the curve bath agreed with mutually with described lock plate in the middle of adjacent two described elongated slots; The rotational axis of described lock plate overlaps with described driving crank.
Further, described finger is parallel with described lock plate rotational axis.
Further, the length of described elongated slot is less than the distance of described finger turning axle to described lock plate.
The utility model also provides a kind of tool magazine, has above-mentioned Geneva mechanism.
Compared with prior art, the beneficial effects of the utility model are:
Adopt driving crank and this mates of sheave, finger on driving crank and lock plate agree with mutually with the elongated slot on sheave body and curve bath respectively, by the rotation of driving crank, when the finger on active bent axle enters in groove, just stir sheave and do reverse indexing campaign, when finger is deviate from from groove, sheave and transfixion are also located by lock plate, reach the object uniform motion of driving crank being converted to the rotary motion of sheave body intermittent type.
Accompanying drawing explanation
Fig. 1 is the utility model preferably Geneva mechanism structural drawing.
