Abstract
The invention relates to the technical field of elevator mechanisms, and particularly to a mechanism capable of doing tiny up-and-down movement. The mechanism capable of doing tiny up-and-down movement comprises a box body, a motor, a lever and a push rod, wherein a partition plate is arranged inside the box body; the push rod is arranged at the axis of the box body; the lower end of the push rod extends to the bottom side of the partition plate to be in contact with the top surface of the lever which is obliquely arranged on the bottom of the partition plate; the top end of the push rod extends to the top end of the box body and is provided with a workbench; the motor is arranged on the bottom of the partition plate and is close to one upwards oblique side of the lever; the output shaft of the motor is provided with a cam; the cam corresponds to the upwards oblique end of the lever. The mechanism capable of doing tiny up-and-down movement is simple in structure and convenient to adjust, and can do tiny and steady up-and-down movement.
Description
Technical field
The present invention relates to lifting mechanism technology field, be specifically related to a kind of mechanism that can smallly move up and down.
Background technique
Existing can the mechanism of vertical up-or-down movement generally with cylinder or Driven by Hydraulic Cylinder, air cylinder driven is not steady, and the stroke ratio of air cylinder driven is larger, oil hydraulic cylinder is convenient to control but cost is higher, there is significant limitation, cylinder, oil hydraulic cylinder are suitable for driving larger the moving up and down of stroke, and its structure of other driving mechanism is general comparatively complicated, too increases cost to a certain extent.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned defect, provides a kind of mechanism that can smallly move up and down, and structure is simple, easy to adjust, moves up and down small and steady.
The technological scheme that the present invention solves the employing of its technical problem is as follows:
A kind of mechanism that can smallly move up and down, comprise casing, motor, lever, push rod, described box house is provided with dividing plate, described push rod is arranged on casing axle center place, push rod lower end extends to dividing plate bottom side and contacts with the lever end face be inclined at bottom dividing plate, push rod top extends to casing top and is provided with worktable, described motor is arranged on bottom dividing plate near side acclivitous with lever, motor output shaft is provided with cam, cam and the lever one end that is inclined upwardly is corresponding, motor output shaft place is provided with speed reducer, the moment of torsion that motor exports passes to cam after speed reducer slows down, cam rotates, the movement of smiling up and down is then done with the lever of cam engagement, corresponding lever pushes push rod and does small moving up and down, make that worktable is small to be moved down, the shape of cam is regular, contact with lever compact, the fine motion making worktable upper and lower is steady, be conducive to improving precision when worktable moves up and down, and change different cams, the degree of different fine motions can be realized, convenient control, structure is simple, reduce costs, and push rod corresponds to the medium position of lever, this place is not the maximum position place of lever motion, with lever length than the reduction that will move up and down, and the degree that worktable moves up and down is changed in the position that the position of adjustment lever or adjustment lever contact with push rod, with lever ratio, vertical motion is reduced.
Further, described push rod and dividing plate, casing contacting point are provided with sliding sleeve, sliding sleeve is fixed on casing or dividing plate, push rod shaft corresponding bottom casing upper sliding sleeve is provided with projection, push rod shaft between projection and dividing plate upper sliding sleeve is provided with spring, push rod spring when moving down is compressed, and spring plays auxiliary reset effect.
Further, the downward-sloping one end of described lever is flexibly connected with casing, push rod and lever contact place are the arc structure of downward protrusion, circular arc mechanism is convenient to better contact with lever, lever one end is flexibly connected with casing, arc structure make lever with casing active connection place for the axle the other end move up and down time, the motion of lever, lever and push rod coordinate that to push push rod more smooth.
Further, described lever and cam corresponding part are provided with roller, and roller reduces wear, and avoid cam, lever to wear and tear, increase the service life.
The invention has the beneficial effects as follows: adopt such scheme, pass to worktable after utilizing lever ratio the motion of cam curve word Vertical direction to be reduced, in the process of fine motion steadily, and improve the precision moved upward, overall structure is simple, and cost is low.
Accompanying drawing explanation
