The synchronous belt automatic belt pulley 2 is arranged on an output shaft 101 of the stepping motor and drives the driving wheel 4 via the synchronous belt 3, the rotary barrel stepping mechanism is further provided with a grooved pulley 5, a disc 6 with an unfilled corner is coaxially arranged on the driving wheel 4 and is a disc with a cutout arc, the driving wheel 4 is provided with a protruded column 401, the trace line of the outer edge of the grooved pulley is not assembled with the unfilled corner of the disc, a plurality of radial grooves 501 are arranged on the grooved pulley and are arranged around the circle center of the grooved pulley in a scattered manner, grooves 502 which are meshed with the disc with the unfilled corner are arranged on the outer edge of the grooved pulley among the radial grooves, the aperture of each radial groove is larger than that of the protruded column, and axial projections of notches of the radial grooves are coincident to the traveling trace of the protruded column 401. The rotary barrel stepping mechanism has the advantages of accurate positioning and capabilities of realizing a self-locking function and reducing power consumption of the motor, and can be widely applied to intermittent periodic motion structures.
Description
Technical field
The utility model relates to stepping mechanism, particularly the rotary barrel type stepping mechanism.
Background technique
Existing stepping lazy-tongs are normally driven by stepper motor and are with synchronously from movable belt pulley, are with synchronously from movable belt pulley and turn round through driving driving wheel synchronously, to reach synchronous purpose.But deficiencys such as synchronized positioning is inaccurate take place in this mechanism sometimes.
Summary of the invention
The purpose of the utility model is to provide a kind of rotating cylinder stepping mechanism of accurate positioning.
The purpose of the utility model can realize like this, designs a kind of rotating cylinder stepping mechanism, comprises stepper motor, is with from movable belt pulley, synchronous band, driving wheel synchronously; Synchronous band is set from movable belt pulley on the output shaft of stepper motor, band drives driving wheel from movable belt pulley through being with synchronously synchronously, also is provided with sheave; The coaxial unfilled corner disk that is provided with on the driving wheel, the unfilled corner disk is the disk of intercepting one circular arc, and a protruding post is set on the driving wheel; The outer rim trajectory of sheave and the unfilled corner incongruity of unfilled corner disk; Some radial grooves are set on the sheave, and this radial groove is dispersed setting with the sheave center of circle, and the sheave outer rim between the radial groove is provided with the groove with unfilled corner disk inscribe; The caliber size of radial groove overlaps with the run trace of protruding post from axial direction projection radial groove notch greater than the caliber size of protruding post.
The utlity model has accurate positioning, have auto-lock function, reduce the advantage of motor power consumption, can be widely used in the intermittent periodic motion structure.
Description of drawings
Fig. 1 is the structural representation of the utility model preferred embodiment;
Embodiment
Below in conjunction with embodiment the utility model is done further to describe.
As shown in Figure 1, a kind of rotating cylinder stepping mechanism, comprise stepper motor 1, synchronously band from movable belt pulley 2, be with 3 synchronously, driving wheel 4; Synchronous band is set from movable belt pulley 2 on the output shaft 101 of stepper motor, band through being with 3 to drive driving wheel 4 synchronously, also is provided with sheave 5 from movable belt pulley 2 synchronously; The coaxial unfilled corner disk 6 that is provided with on the driving wheel 4, unfilled corner disk 6 is the disk of intercepting one circular arc, and a protruding post 401 is set on the driving wheel 4; The outer rim trajectory of sheave and the unfilled corner incongruity of unfilled corner disk; Some radial grooves 501 are set on the sheave, and this radial groove 501 is dispersed setting with the sheave center of circle, and the sheave outer rim between the radial groove is provided with the groove 502 with unfilled corner disk inscribe; The caliber size of radial groove overlaps with the run trace of protruding post 401 from axial direction projection radial groove notch greater than the caliber size of protruding post.
Angle between the said radial groove 501 adjacent radial grooves is 60 °.Make this rotating cylinder mechanism can stablize, rotate accurately 60 °.
Said protruding post 401 is arranged on the diameter line in the middle of the unfilled corner disk unfilled corner, lets sheave 5 projections accurately through the unfilled corner part.Said protruding post 401 is a straight pin.
Sheave outer rim between the radial groove is provided with the groove 502 with unfilled corner disk inscribe, and this groove and unfilled corner disk complete circle segmental arc are coincide, and the circular arc center of circle of this groove is concentric with the center of circle of unfilled corner disk complete circle segmental arc.
After stepper motor 1 starts; Band moves with stepper motor 1 from movable belt pulley 2 synchronously; Driving wheel 4 setting in motion under synchronously with 3 drive, when the straight pin on the driving wheel 401 got into radial grooves 501, sheave 5 beginnings were rotated thereupon; Turn over 60 ° of straight pins 401 on the rear drive sprocket at sheave and break away from radial groove 501, sheave 5 stops operating.After straight pin 401 produced radial groove 501, sheave 5 stopped operating.Straight pin 401 continues rotation until rotating a week, and sheave 5 is accomplished once commentaries on classics and stopped transport moving.
Utilize the Geneva mechanism can accurate localization, driving wheel 4 rotates a circle, 60 ° of sheave 5 rotations, and corner is accurate, reliable operation, mechanical efficiency is high.The disk 6 that has breach on the driving wheel has the effect that locks sheave 5, and after sheave 5 stop motions, locking sheave 5 prevents the attendant mechanism on the sheave because inertia drives the sheave rotation.Reduced requirement simultaneously, reduced the power consumption of stepper motor 1 stepper motor 1.The utlity model has accurate positioning, have auto-lock function, reduce the advantage of motor power consumption, can be widely used in the intermittent periodic motion structure
