Background technique
In machining, ground observation work; use worktable through regular meeting; in order to ensure machining accuracy; can require worktable must be in the abswolute level state; but because the restriction in place; particularly open-air, can't find a complete smooth ground, so using to the related personnel, this has brought unnecessary trouble.How to relate to a kind of worktable, he can regulate the technical barrier that the table top level is related domain automatically according to need not to consider ground flat degree.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of worktable of automatic adjusting level, when this worktable has solved worktable and needs horizontal positioned, because the ground out-of-flatness, causes the technical problem that table top can't level.
The invention provides a kind of worktable of automatic adjusting level, comprising: be used for to support the leg assembly of at least three adjustment heights of described table top, described leg assembly comprises: upper supporting leg and following supporting leg, and be located at elevator mechanism between the upper and lower supporting leg; Described elevator mechanism comprises: cylindrical, and be used for filling the cylinder body of buffer medium, opening end sealing at this cylinder body is provided with cylinder cap, the sealing activity is combined with a piston rod in the central through bore of described cylinder cap, the upper end of this piston rod is provided with the piston body assembly, and this piston body assembly cooperates with the inwall movable sealing of described cylinder body; Be provided with some through holes in the described piston body assembly, this through hole is suitable for control and opens or closes, so that medium circulates or ends, the described upper-end surface of supporting leg down is fixed in the lower end of described piston rod, and the lower end surface of described upper supporting leg is fixed in the upper-end surface of described cylinder body; The side of described cylinder body and cylinder cap place are provided with the hydraulic pressure inlet/outlet respectively, and this hydraulic pressure inlet/outlet links to each other with an oil hydraulic pump by hydraulic line; The lower end surface of described table top is provided with a double-shaft level sensor, and this level sensor links to each other with a processor unit; When described table top was out-of-level, described processor unit made described table top level according to the elevator mechanism work in the horizontal signal control respective leg assembly of double-shaft level sensor; Wherein, described processor unit is controlled described through hole and is opened, medium flows to its below from described piston body assembly top, described cylinder body is moved downward, to reduce the height of corresponding upper supporting leg, or close through hole, start described oil hydraulic pump, make medium flow to its top by hydraulic line from described piston body assembly below, described cylinder body is moved upward, with the height of the corresponding upper supporting leg that raises, until the table top level.
Further, described piston body assembly comprises: the upper and lower piston body of coaxial setting, described through hole is located on this upper and lower piston body, and be symmetrical arranged, being sealed and matched between the adjacent face of upper and lower piston body, so that when making the piston body assembly and moving upward, described medium is only realized flowing by each through hole on the described upper and lower piston body; Be provided with in the described lower piston body for the cavity of placing motor, this motor is controlled by described processor unit, and its rotor is connected in described upper piston body, is used for driving this upper piston body rotation, opens or closes described through hole.
Further, described hydraulic line is connected with one-way valve.
Compared with prior art, the present invention has following advantage: (1) the present invention realizes the height of landing leg adjusting by being located at the elevator mechanism of each leg assembly, with control worktable level, need not to consider the flatness on ground; (2) by through hole control media flow size, can control upper supporting leg and regulate the speed, improve the self-adjusting speed of worktable.
