For face lower position to installation base is convexed to form, which is equipped with third guide rail.
As a kind of improvement of the utility model, the both ends of the surface of the load receiving part are equipped with hollow out hole.Ensureing that entirety is firm
Property and structural strength on the basis of, reduce materials to greatest extent, reduce cost, while also accordingly mitigate weight, job stability
More preferably.
As a kind of improvement of the utility model, the front medium position of the load receiving part is equipped with driving device mounting base.
Ingenious to install driving device using space, which can be used for that head slide is driven to make bilateral reciprocation.Structure
It is compact, effectively reduce occupied space.
As a kind of improvement of the utility model, two stabilizer blade bottom leading edge locus of gantry frame body extend to form forward
Add support portion, effectively increase and the contact area of pedestal, the stability for placing installation is good.
As a kind of improvement of the utility model, the upper top side location of the load receiving part is equipped with mutually fits with first guide rail
The first fitting groove matched.The front upper position of the load receiving part is equipped with the second fitting groove being adapted with second guide rail.
The front of the installation base is equipped with the third fitting groove being adapted with the third guide rail.Fast and easy location and installation, and
Fitting tight, stability are good.
The beneficial effects of the utility model are：The utility model is ingenious in design, by rationally in the load receiving part of gantry frame body
The position of the first guide rail of upper arrangement, the second guide rail and third guide rail, and be effectively formed multi-faceted not on same installation base surface
Stress support construction, support effect is good, and load capacity is strong, operates steadily, and greatly improves stability during complete machine work, processing
Precision is high, ensures product quality；Gantry frame body two side is stretched out at the both ends of load receiving part simultaneously, accordingly extends the row of head slide
Journey, and then effectively expand the range of work, it is applied widely.
Below in conjunction with the accompanying drawings with embodiment, the utility model is further illustrated.
Description of the drawings
