Background technology
Workbench is to be machined the process unit that can all configure of factory, and traditional workbench is in order to meet the need of stabilized structure
Ask, can not freely adjust height substantially, but in production due to the difference of personnel's height often result in bend over or feet etc. no
Comfortable job state, very big inconvenience is brought to production.With the development of technology, some workbench that can adjust height should
Transport and give birth to, but its to be all largely the governor motion for installing complexity additional realize, make that Working table structure is more complicated, improve into
Sheet, and troublesome poeration, practicality is not strong.
The content of the invention
In view of the above-mentioned problems of the prior art, the purpose of this utility model, which is to provide one kind, is ensureing that overall structure is steady
Gu while, design succinct, simple to operate, workman can freely adjust height, the adjustable work of convenient production according to stature
Make stand.
To achieve the above object, the technical solution adopted in the utility model is:A kind of adjustable Working gantry, including work
Make table top and table base, work top and table base are connected by crotch, the crotch is arranged including Parallel Symmetric
Two X-type supports, the bottom support end of each X-type support is all hinged on table base, the bottom mobile terminal of X-type support
It is fixed together by sliding pin with being in the cooperation of conplane chute on table base with X-type support;The X-type support
On the support end of bottom Founder to top fixing end be hinged on Founder on work top lower surface, bottom mobile terminal to top move
Moved end is equipped with the guide groove that work top lower surface is set, and can be slided along guide groove, the guide groove and X-type branch
Frame is in same plane;The top mobile terminal of two X-type supports is linked together by connecting rod, and the connecting rod is provided with
Transmission nut, the transmission nut is enclosed on the ball screw of work top lower surface setting and can slided along ball screw,
The length direction of the ball screw is parallel with the length direction of guide groove.
It is preferred that, in order to strengthen overall intensity, supporting degree, increase the service life, the X-type support is X-type stainless steel
Support.
It is preferred that, move for convenience, mitigate the overall weight of workbench, the table base is by many stainless steel squares
Pipe is welded.
It is preferred that, in order that mobile and height regulation is more smooth, top mobile terminal is scroll wheel.
It is preferred that, the ball screw is located at work top lower surface middle, and transmission nut is located at connecting rod center
Between.
It is preferred that, the work top is foldable.
It is preferred that, in order to more facilitate operation, ball screw one end extends work top and end is provided with rotating handles.
The utility model design structure is ingenious, easy to operate, when the workman of different heights needs adjustment work platform height, directly
The parallel lifting up and down that work top can be achieved in swing roller screw mandrel is connect, overall stability is not influenceed in lifting, and it is right
The X-type support of title ensure that overall stabilized structure;Low manufacture cost, and facilitate being normally carried out for production.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As illustrated, a kind of adjustable Working gantry, including work top 1 and table base 2, the He of work top 1
Table base 2 is connected by crotch 5, and the crotch 5 includes two X-type supports that Parallel Symmetric is arranged, each X-type support
Bottom support end 5a is all hinged on table base 2, and the bottom mobile terminal 5b of X-type support passes through sliding pin and table base
The cooperation of conplane chute 3 is on 2 with X-type support to be fixed together;It is upright right on the X-type frame bottom support end 5a
Top fixing end 5c be hinged on the lower surface of work top 1, bottom mobile terminal 5b it is upright to top mobile terminal 5d coordinate and set
Put in the guide groove 7 that the lower surface of work top 1 is set, and can be slided along guide groove 7, the guide groove 7 is in X-type support
In same plane;The top mobile terminal 5d of two X-type supports is linked together by connecting rod 4, and the connecting rod 4 is provided with one
Transmission nut 6, the transmission nut 6 is enclosed on the ball screw 8 of the lower surface of work top 1 setting and can be along ball screw 8
Slide, the length direction of the ball screw 8 is parallel with the length direction of guide groove 7.
During using structure of the present utility model, transmission nut 6 is enclosed on ball screw 8 and can be along ball screw 8 back and forth
Slide;When workman needs the height of adjustment work table top 1, direct swing roller screw mandrel 8, transmission nut 6 can coordinate edge with it
Ball screw 8 slidably reciprocates, because transmission nut 6 is fixed in connecting rod 4, can be along ball screw 8 so that connecting rod 4 is overall
Length direction movement, i.e., the top mobile terminal 5d of two X-type supports is simultaneously respectively along the synchronous slide of guide groove 7, X-type support
The angle opened changes, so as to change height of the work top 1 apart from ground.
It is preferred that, in order to strengthen overall intensity, supporting degree, increase the service life, the X-type support is X-type stainless steel
Support.
It is preferred that, move for convenience, mitigate the overall weight of workbench, the table base 2 is by many stainless steels
Square tubes soldering is formed.
It is preferred that, in order to reduce friction, mobile and height is adjusted more smooth, top mobile terminal 5d is designed as scroll wheel.
It is preferred that, the ball screw 8 is located at the lower surface middle of work top 1, and transmission nut 6 is located at connecting rod 4
Middle.
It is preferred that, the work top 1 is foldable.Folding workbench can expand usable floor area as needed,
The space that used time does not take is also smaller.
It is preferred that, in order to more facilitate operation, work top 1 is extended in the one end of ball screw 8 and end is provided with rotation handle
