Description
Technical field
The utility model relates to a kind of elevating mechanism, relates in particular to a kind of height adjustment mechanism.
Background technology
Elevating mechanism is a kind of conventional frame for movement, generally adopts cylinder, hydraulic cylinder etc.
In order to realize the step-less adjustment on height, need to adopt a kind of height adjustment mechanism that comprises servomotor, this height adjustment mechanism generally comprises motor, screw mandrel, at least one guide post, nut and slide block, wherein screw mandrel and guide post be arranged in parallel, motor is connected with screw rod transmission, nut is meshed with screw mandrel, and slide block is arranged on guide post and can slides up and down along guide post, and slide block is connected with nut.Motor drives screw mandrel to rotate, and under the restriction of guide post, nut band movable slider slides up and down along guide post, thereby has realized the step-less adjustment on height by the interaction up and down of slide block.
Above-mentioned height adjustment mechanism is when the horizontal plane that is applied to sole pressing mechanism regulates, also need a push rod, the lower end of push rod is connected with slide block, for guaranteeing the steady of push rod, also a fairlead need to be set in the outside of push rod again, prevent that the upper end of push rod from departing from centre position.
Therefore, above-mentioned height adjustment mechanism, when the horizontal plane that is applied to sole pressing mechanism regulates, needs screw mandrel, guide post, at least three bodies of rod of push rod to be arranged side by side, and needs four bodies of rod to be arranged side by side in the situation that two guide posts are set.Such structure is more complicated, loose undoubtedly, has not only increased material cost, and due to compact not in structure, taken larger space, cause the volume of complete machine larger, take larger factory building area, this causes great waste undoubtedly in the modern society at an inch of land is an inch of gold.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of height adjustment mechanism, and the compact conformation of this height adjustment mechanism takes up room little, reduces manufacturing cost.The technical scheme adopting is as follows:
A height adjustment mechanism, comprises support, motor, screw mandrel and push rod, it is characterized in that: also comprise lifting central siphon and pilot sleeve; Motor and pilot sleeve are all vertically arranged on described support; Lifting central siphon is in pilot sleeve, and the lower end of push rod is connected with the upper end of lifting central siphon; Screw mandrel is in lifting central siphon, and the output shaft of motor and the lower end of screw mandrel are in transmission connection; The madial wall of lifting central siphon is provided with internal thread, and screw mandrel is meshed with internal thread; Between pilot sleeve and lifting central siphon, be provided with lower guide mechanism.
Motor drives screw mandrel moving in the transfer of lifting central siphon, because screw mandrel is meshed with internal thread, make lifting shaft pipe there is the movement tendency of rotation, the movement tendency also with oscilaltion, but because pilot sleeve maintains static, therefore, under the restriction of the upper lower guide mechanism between pilot sleeve and lifting central siphon, lifting central siphon can only be done oscilaltion campaign in pilot sleeve, thereby makes the push rod being connected with lifting central siphon do oscilaltion campaign, reaches the object highly regulating.Motor drives screw mandrel moving in the transfer of lifting central siphon, and because lifting lifting central siphon, push rod partly can not rotate and only do elevating movement, so the lifting of push rod is quite steady, is applicable to the adjusting that precision is higher; Because the output shaft of push rod, lifting central siphon, pilot sleeve, screw mandrel and motor is all on same axis, simple and compact for structure, material usage obviously reduces, and has reduced manufacturing cost; And outmost pilot sleeve is depended in the shared space of whole height adjustment mechanism, it is little that this is arranged side by side shared space more than several bodies of rod in prior art, thereby significantly reduced taking up room of complete machine, reduce the construction area of factory building, in the modern society of an inch of land is an inch of gold, its economic benefit is very obvious.This height adjustment mechanism is applicable to lift adjustment in general device, horizontal plane regulates, and the horizontal plane that is particularly useful for sole pressing mechanism regulates.
As preferred version of the present utility model, described upper lower guide mechanism comprises the longitudinal fluting that is arranged on described lifting central siphon lateral wall and is arranged on the slide block on described pilot sleeve madial wall, and slide block is in longitudinal fluting.By the cooperation of slide block, longitudinal fluting, stop the rotation of lifting central siphon, force lifting central siphon can only do oscilaltion campaign, so upper lower guide mechanism is simple, practical, and stability is stronger.Certainly, longitudinal fluting also can be arranged on the madial wall of pilot sleeve, and slide block is arranged on the madial wall of lifting central siphon.Upper lower guide mechanism also can be arranged on the spline joint between pilot sleeve madial wall and lifting central siphon lateral wall.
As preferred version of the present utility model, described internal thread is only arranged on the bottom of described lifting central siphon.Internal thread is arranged on to the bottom of lifting central siphon, has both guaranteed maximum effective lifting distance, reduced again the friction between screw mandrel and lifting central siphon, thereby reduce the power output of motor, save the energy, energy-conserving and environment-protective more, reduce production costs.
As the further preferred version of the utility model, also comprise gripper shoe, on described support, be vertically provided with a plurality of annular slots, gripper shoe is in one of them annular slot, and described motor, pilot sleeve are installed in gripper shoe.By manual adjustments gripper shoe in different annular slots, make the whole oscilaltion of push rod, lifting central siphon, pilot sleeve, screw mandrel and motor, settle at one go, by screw mandrel, lifting central siphon, finely tune again, be applicable to significantly lift adjustment, the height that is specially adapted to production conventional shoe, boots regulates.
As the further preferred version of the utility model, also comprise shaft coupling, the output shaft of described motor is connected with described screw mandrel by shaft coupling.The output shaft of realizing motor by shaft coupling is connected with screw rod transmission, connects simple and conveniently, and guarantees that motor output shaft is connected with the coaxial of screw mandrel.
