Description
Technical field
The present invention relates to precision debug and field of measuring technique, be specifically related to a kind of manual/automatic integrated adjustable supporting
Lower limb.
Background technology
Common adjustable support leg mainly has hydraulic leg and the big class of mechanical lag two.Hydraulic leg is due to can not
There is interior leakage problem with avoiding, the stability of system certainly will be affected, need to be added with locking mechanism.Machinery
Lower limb is compared with hydraulic leg, has certain superiority in terms of long-time stability.Mechanical lag is main
Having flange join type and screw connected two kinds, the former is respectively arranged with a flange on table top and supporting leg, passes through
Bolt connects；The latter is then table top and supporting leg to be coupled together by screw rod and nut, utilize long screw and
Pair of nut completes the flexible of supporting leg, locks with locking nut.
Adjustable support leg mainly uses manual adjusting screw rod or hydraulic jack to realize displacement regulation, also at present
Can realize being automatically adjusted by increasing motor, but manual mode and automatic mode can not realize and side simultaneously
Just switch.
Summary of the invention
In order to solve problems of the prior art, the invention provides a kind of manual/automatic integrated adjustable supporting
Lower limb, has manual/auto leveling one, easy to adjust, the feature of simple in construction.
It is as follows that the present invention solves the technical scheme that technical problem used:
A kind of manual/automatic integrated adjustable support leg, this supporting leg includes: manual knob, through axial linear motor,
Upper switching fixed plate, it is deleveled platform, bottom plate, limit base, driving screw and fixing supporting legs；Manually
Together with knob is co-axially mounted with through axial linear motor；Upper switching fixed plate is fixedly mounted on through shaft
Below formula linear electric motors；It is deleveled platform by being arranged on below upper switching fixed plate thus straight with through shaft type
Line motor is fixing to be connected；Driving screw is coaxially connected with the through shaft lower end of through axial linear motor；Guide screw
The lower end of bar is fixing with bottom plate to be connected；Bottom plate is fixed in fixing supporting legs；Limit base is fixed
In fixing supporting legs, by regulation manual knob or through axial linear motor, make to be deleveled platform in limit
The spacing range of motion of position seat.
The invention has the beneficial effects as follows: the present invention passes through existing leg branching part, present have manually and
Automatic both of which, realize simultaneously, conveniently switch and keep the one adjustable support leg of precision, overall knot
Structure is simple, easy to use during regulation, easily makes, can be widely used in and have displacement of the lines accurately
The high accuracy levelling gear of adjustment demand.
Accompanying drawing explanation
The structural representation of a kind of manual/automatic integrated adjustable support leg of Fig. 1 present invention.
In figure: 1, manual knob, 2, through axial linear motor, 3, be deleveled platform, 4, driving screw,
5, limit base, 6, upper switching fixed plate, 7, bottom plate and 8, fixing supporting legs.
Detailed description of the invention
With embodiment, the present invention is described in further details below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of manual/automatic integrated adjustable support leg, this supporting leg includes: manual knob 1, through
Axial linear motor 2, upper switching fixed plate 6, it is deleveled platform 3, bottom plate 7, limit base 5, driving screw
4 and fixing supporting legs 8；Together with manual knob 1 is co-axially mounted with through axial linear motor 2；Manually
It is connected firmly with the through shaft of through axial linear motor 2 by the side of knob 1 by jackscrew, and through shaft type is straight
Line motor 2 is fixed in upper switching fixed plate 6 by shaft mode, and recycling screw is by upper switching fixed plate 6
Connect firmly with being deleveled platform 3.Driving screw 4 is coaxially connected with the through shaft lower end of through axial linear motor 2；Lead
The lower end of screw rod 4 is fixing with bottom plate 7 to be connected；Bottom plate 7 is fixed in fixing supporting legs 8；Spacing
Seat 5 is fixed in fixing supporting legs 8, by regulation manual knob 1 or through axial linear motor 2, make by
Leveling platform 3 is at the spacing range of motion of limit base 5.Regulation stroke depends on type selecting and the limit of linear electric motors 2
The size design of position block 5.
The work process utilizing the present invention to realize manual/automatic integrated adjustable support leg is:
(1), under manual work pattern: driving screw 4 is fixed on bottom plate 7, rotary manual revolves
Button 1 drives through shaft to rotate, thus drives through axial linear motor 2 and be deleveled platform 3 along driving screw
4 directions move up and down；
(2) under automatic operation mode: driving screw 4 is fixed on bottom plate 7, and through shaft type is straight
When line motor 2 works, through shaft rotates and motor is moved up and down along driving screw 4 direction, thus drives quilt
Leveling platform 3 moves up and down.
Claims (1)
1. a manual/automatic integrated adjustable support leg, it is characterised in that this supporting leg includes: manual knob, pass through
