Description
Technical field
The utility model relates to a kind of transmission device, and a kind of is specifically the device of rotary motion by transform linear motion, belongs to technical field of mechanical transmission.
Background technique
In in industrial automation, meeting ubiquity needs that transform linear motion is rotary motion, the way that prior art is taked generally uses slidercrank mechanism, and the motion of its slide block moving linearly drivening rod carrys out driving crank and rotates; Or pinion and rack, its tooth bar moving linearly carrys out actuation gear and rotates.
The slidercrank mechanism used in prior art has gap, and precision is low, and structure adaptability is little; Pinion and rack then requires high in processing and installing, drive noise is large, weares and teares also large.
And for some mechanism needing circumferentially slightly rotation, no matter be slidercrank mechanism or pinion and rack in prior art, all seeming, structure is more complicated, implement inconvenient, economical poor.
Model utility content
The utility model technical issues that need to address are: of the prior art is the device of rotary motion by transform linear motion, and complicated structure is economical poor, and exist or precision low, structure adaptability is little; Or install and require high, drive noise is large, large problem of wearing and tearing.
The utility model takes following technological scheme:
Be a device for rotary motion by transform linear motion, comprise and sliding along described slide rail to the slide rail arranged, slide block 1 along X; Described slide block 1 side is fixed with contiguous block 8, and contiguous block 8 is provided with the bearing roller 6 perpendicular to XOY plane, and described contiguous block 8 is flexibly connected by extension spring 4 and link 5; Described link 5 is connected with plane bearing 7, and plane bearing 7 can be driven to rotate around its axis of rotation 3; When described slide block 1 is along described slide rail X to slip, extension spring 4 pulls link 5 to rotate forward, and when described slide block 1 is along described slide rail-X to slip, contiguous block 8 promotes link 5 and rotates backward, and bearing roller 6 and link 5 keep tangent.
Further, described bearing roller 6 both sides are respectively provided with an extension spring 4.
Further, described plane bearing 7 outside is fixedly connected with rotating structural elements 2.
Further, the described transmission by transform linear motion being the device of rotary motion and being used for slightly rotating, the rotation angle of its rotating structural elements 2 is ± 10 °.
The beneficial effect of model utility is:
1) than existing slidercrank mechanism, precision is higher, strong adaptability;
2) than existing pinion and rack, installation requirement is lower, and noise is lower, weares and teares less.
3) employing flexibly connects, and structure is relatively simple, by force economical.
4) mechanism of small size reciprocating rotation is particularly useful for.
Accompanying drawing explanation
The appearance schematic diagram of Fig. 1 to be the utility model by transform linear motion be device of rotary motion.
The perspective view of Fig. 2 to be the utility model by transform linear motion be device of rotary motion.
In figure, 1. slide block, 2. rotating structural elements, 3. axis of rotation, 4. extension spring, 5. link, 6. bearing roller, 7. plane bearing, 8. contiguous block.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
See Fig. 1-Fig. 2, a kind of is the device of rotary motion by transform linear motion, comprises and sliding along described slide rail to the slide rail arranged, slide block 1 along X; Described slide block 1 side is fixed with contiguous block 8, and contiguous block 8 is provided with the bearing roller 6 perpendicular to XOY plane, and described contiguous block 8 is flexibly connected by extension spring 4 and link 5; Described link 5 is connected with plane bearing 7, and plane bearing 7 can be driven to rotate around its axis of rotation 3; When described slide block 1 is along described slide rail X to slip, extension spring 4 pulls link 5 to rotate forward, and when described slide block 1 is along described slide rail-X to slip, contiguous block 8 promotes link 5 and rotates backward, and bearing roller 6 and link 5 keep tangent.
See Fig. 2, described bearing roller 6 both sides are respectively provided with an extension spring 4.
See Fig. 2, described plane bearing 7 outside is fixedly connected with rotating structural elements 2.
The described transmission by transform linear motion being the device of rotary motion and being used for slightly rotating, the rotation angle of its rotating structural elements 2 is ± 10 °.
Concrete structure illustrates: slide block 1 drives moving linearly by driving and gear unit; Rotating structural elements 2 is fixed on plane bearing 7 inner ring; Fixed end is fixed in plane bearing outer ring 7; Link 5 is fixed on rotating structural elements; Slide block 1 is fixed in the axle center of bearing roller 6; Bearing roller 6 contacts with link 5 (can roll and keep tangent with link in bearing roller outer ring);
Principle illustrates: the thrust that slide block straight line motion is formed provides torque to rotating structural elements, makes it to rotate around axis of rotation;
Action specification: driving element drives and transmitted by transmission component, band movable slider moving linearly, be fixed on the bearing roller on slide block under the effect of extension spring, keep in touch with the link be fixed on rotating structural elements, the thrust that slide block straight line motion produces thus is delivered on rotating structural elements, be converted into the torque of rotational structure, thus make it to rotate around axis of rotation.
Model utility is than existing slidercrank mechanism, and precision is higher, strong adaptability; Than existing pinion and rack, installation requirement is lower, and noise is lower, weares and teares less; Employing flexibly connects, and structure is relatively simple, by force economical; Be particularly useful for the mechanism of small size reciprocating rotation.
On the basis of the present embodiment, those skilled in the art can carry out proper transformation to it, can realize function of the present utility model equally, such as:
1. also can realize when link and rotating structural elements are made of one time;
2. also can realize when the bearing roller on slide block changes the element of other low frictions (no matter being rolling friction or sliding friction) into;
3. also can realize when bearing roller and this flexible connection mode of link are substituted by other flexible connection modes.
Above-mentioned mapping mode should also belong within the claimed scope of the utility model.
