Abstract
The invention discloses a stroke regulating mechanism for a double-rod hydraulic cylinder. The stroke regulating mechanism comprises a threaded regulating section arranged on the end portion of a piston rod on one side. The length of the threaded regulating section is greater than the distance of the stroke needing to be regulated of the piston rod. A regulating gear is movably arranged on the threaded regulating section through threads in a sleeving mode. The regulating gear is engaged with a drive gear rotationally arranged on an installing base. A servo motor driving the drive gear to rotate is arranged on the installing base. The tooth width of the drive gear is greater than the stroke of the hydraulic cylinder. When the piston rod arranged on the side, close to the regulating gear, of the hydraulic cylinder extends out completely, the distance between a hydraulic cylinder cover directly facing the regulating gear and the end face of the regulating gear is shorter than the distance between the end portion on the side, close to the hydraulic cylinder, of teeth of the regulating gear and the end portion on the side, close to the hydraulic cylinder, of teeth of the drive gear. The stroke regulating mechanism for the double-rod hydraulic cylinder is simple and reliable in control, high in precision, low in cost and suitable for large-tonnage double-rod hydraulic cylinders.
Description
Technical field
The present invention relates to a kind of hydraulic equipment, relate in particular to the stroke control mechanism of a kind of pair of outlet-rod hydraulic cylinder.
Background technique
Existing large-tonnage hydraulic location device, the overwhelming majority adopts oil cylinder location, and namely employing pair goes out rod oil cylinder, in conjunction with adjusting nut location, can only have a kind of position during its work, and adjustment must shut down rear manual setting; Another kind of employing servo-cylinder, but during its work, piston stops in neutral position, but the words of plus load, its position has fluctuation, although finally can get back to original position, in course of working, this positional fluctuation can cause the generation of waste product, and its system cost is high, control difficulty; Also have a kind of employing electric cylinder, by Serve Motor Control, overall structure is fairly simple, but required applicable tonnage is larger, and screw mandrel and the rating of machine of needs use are larger, with high costs needed for it.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of and control the stroke control mechanism being applicable to the two outlet-rod hydraulic cylinder of large-tonnage simple and reliable, that precision is high, with low cost.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: the stroke control mechanism of a kind of pair of outlet-rod hydraulic cylinder, be included in the threaded adjusting section that piston rod end, side is arranged, the length of threaded adjusting section is greater than the distance that piston rod needs adjustment stroke, threaded adjusting section is provided with adjusting gear by screw thread movable sheath, adjusting gear is meshed with the rotation actuation gear be arranged on fitting seat, fitting seat is provided with the actuating motor driving actuation gear to rotate, and the facewidth of actuation gear is greater than hydraulic cylinder travel; On oil hydraulic cylinder when the piston rod of adjusting gear side stretches out completely, just teeth on adjusting gear are less than near oil hydraulic cylinder one side end to the distance of actuation gear teeth near oil hydraulic cylinder one side end to the distance between the oil hydraulic cylinder cylinder cap of adjusting gear and adjusting gear end face.
As the preferred scheme of one, described fitting seat is provided with connecting plate, connecting plate one end is connected with oil hydraulic cylinder cylinder cap, and adjusting gear comprises link together gear and columnar positioning boss, and what connecting plate was provided with that diameter is greater than positioning boss diameter dodges hole.
As the preferred scheme of one, described actuation gear is provided with the installation through hole matched with the force-output shaft of actuating motor, is provided with spline key between the force-output shaft of actuating motor and actuation gear.
The invention has the beneficial effects as follows: this stroke control mechanism controls simple and precision is high; Location is reliable, can not produce and fluctuate by occurrence positions after external force; Economy is high, can complete the accurate location of large-tonnage oil cylinder by small-power servo.
Because fitting seat is provided with connecting plate, connecting plate one end is connected with oil hydraulic cylinder cylinder cap, adjusting gear comprises link together gear and columnar positioning boss, what connecting plate was provided with that diameter is greater than positioning boss diameter dodges hole, only need by connecting plate and oil hydraulic cylinder cylinder cap exact connect ion, can ensure can accurately locate between actuation gear and adjusting gear, reduce the difficulty of location and installation.
Described actuation gear is provided with the installation through hole matched with the force-output shaft of actuating motor, is provided with spline key between the force-output shaft of actuating motor and actuation gear.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In Fig. 1: 1. oil hydraulic cylinder, 2. threaded adjusting section, 3. adjusting gear, 31. gear, 32. positioning boss, 4. actuation gear, 5. fitting seat, 6. actuating motor, 7. spline key, 8. connecting plate, 9. cylinder cap.
Embodiment
Below in conjunction with accompanying drawing, describe specific embodiment of the invention scheme in detail.
As shown in Figure 1, the stroke control mechanism of a kind of pair of outlet-rod hydraulic cylinder, be included in the threaded adjusting section 2 that piston rod end, side is arranged, the length of threaded adjusting section 2 is greater than the distance that piston rod needs adjustment stroke.Threaded adjusting section 2 is provided with adjusting gear 3 by screw thread movable sheath, and adjusting gear 3 is meshed with the rotation actuation gear 4 be arranged on fitting seat 5, and the facewidth of actuation gear 4 is greater than oil hydraulic cylinder 1 stroke.Fitting seat 5 is provided with the actuating motor 6 driving actuation gear 4 to rotate.Actuation gear 4 is provided with the installation through hole matched with the force-output shaft of actuating motor 6, is provided with spline key 7 between the force-output shaft of actuating motor 6 and actuation gear 4.Fitting seat 5 is provided with connecting plate 8, and connecting plate 8 one end is connected with oil hydraulic cylinder 1 cylinder cap 9.Adjusting gear 3 comprises link together gear 31 and columnar positioning boss 32, and what connecting plate 8 was provided with that diameter is greater than positioning boss 32 diameter dodges hole.
On oil hydraulic cylinder 1 when the piston rod of adjusting gear 3 side stretches out completely, just teeth on adjusting gear 3 are less than near oil hydraulic cylinder 1 one side end to the distance of actuation gear 4 teeth near oil hydraulic cylinder 1 one side end to the distance between the end face of positioning boss 32 on oil hydraulic cylinder 1 cylinder cap 9 of adjusting gear 3 and adjusting gear 3.
The working procedure of this device is: after whole mechanism installs, oil hydraulic cylinder 1 bidirectional-movement is total travel, when needs regulator solution cylinder pressure 1 piston rod overhang time, actuating motor 6 drives actuation gear 4 to rotate, adjusting gear 3 is made to follow rotation, because adjusting gear 3 and piston rod are spiral marking connection, adjusting gear 3 can move on the piston rod to the left or to the right, when the piston rod of oil hydraulic cylinder 1 is again to left movement, adjusting gear 3 is blocked by cylinder cap 9 when moving to oil hydraulic cylinder 1 cylinder cap 9 place, make piston rod follow stop motion, thus reach adjustment positioning action.
The above embodiments are the principle of illustrative the invention and effect thereof only, and the embodiment that part is used, but not for limiting the present invention; It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
