Along the first driving structure of the straight line back and forth movement of X-axis slide 10, Y-axis sliding block 11 is installed on the Y-axis line rail 2, the Y-axis is slided
It is connected with block 11 for driving it to come and go the second driving structure slided along Y-axis line rail 2, the Y-axis sliding block 11 is fixed on X-axis
The lower section of slide 10, the workbench 3 of the vertical machining centre are fixed on X-axis line rail 5.
X-axis, Y-axis are commonly used on existing machine tool to distinguish the identification means of two different directions line rails, refer to
Plane-parallel and the orthogonal line rail of two axles, common also has Z axis.Workbench 3 is integrally fixed on X-axis line rail 5, so
Both can be synchronized with the movement, and the first driving structure being connected with X-axis line rail 5 can be direct or indirect drive connection in X-axis
On line rail 5.
Indirect drive connection technical scheme of realizing in the present case is：First driving structure direct drive workbench 3, and work
Make platform 3 drives X-axis line rail 5 to be moved along X-axis slide 10 again.First driving structure includes the first motor 7, the first ball
Leading screw 6, Matching installation has the first nut seat 9 on first ball-screw 6, and the output end of first motor 7 passes through
Transmission belt 8 is connected to be driven the control straight line back and forth movement of the first ball-screw 6, first rolling with the first nut seat 9
Ballscrew 6 is fixed on the workbench 3.Ball-screw is actuated element most-often used on machine tool and precision optical machinery,
It is gyration for converting rotational motion to linear movement with nut seat cooperation, or by transform linear motion.When the first drive
When dynamic motor 7 drives the rotation of the first nut seat 9, it is past straight line to occur with the first ball-screw 6 of the first nut seat 9 cooperation
The motion returned, while drive workbench 3 to be come and gone along X-direction.Cylinder isoline can be used past by the way of direct drive
Return drive mechanism to act directly on X-axis line rail 5, pull its back and forth movement.But from structure assembling and Workpiece Machining Accuracy
From the point of view of considering, this case preferably uses indirect drive mode, that is, directly drives workbench 3, then drives X-axis line rail 5, wherein first drives
The output end of dynamic motor 7 preferably uses gear, and the outer surface of the first nut seat 9 is provided with corresponding groove, so that both pass through
Transmission belt 8 is connected.
Second driving structure include the second motor 13, the second ball-screw 14, second motor 13 it is defeated
Go out end to be connected to drive its rotation with second ball-screw 14 by shaft coupling, pacify on second ball-screw 14
Equipped with rotating with it and the second nut seat 15 of straight line back and forth movement, second nut seat 15 fixes company with Y-axis sliding block 11
Connect.Ball-screw transforms the rotation into be come and gone for the straight line of nut seat, so as to drive Y-axis sliding block 11 to be moved along Y-axis line rail 2, thus
Realize the operation of whole workbench 3 Y direction again.First and motor preferably uses servomotor.
X-axis line rail 5, the quantity of Y-axis line rail 2 are at least two, the vertical friendship of X-axis line rail 5, Y-axis line rail 2 described in each bar
Mutual place is mounted on corresponding X-axis slide 10, Y-axis sliding block 11, as can be seen from Figure 2, the X-axis line rail 5 of respective two, Y-axis line
Rail 2 has four vertical interactions（During depression angle, both are square crossing in this place in the projection of horizontal plane）Place.Just
When the line rail of quantity can also effectively ensure even running of the workbench 3 in all directions cost-effective while.
Both are fixedly connected by a transition block 12 between X-axis slide 10 and corresponding Y-axis sliding block 11, by structure
Refinement, is advantageous to carry out replacing maintenance to each several part.A bottom plate 16 is fixed between each transition block 12, and the second nut seat 15 is solid
Due on the bottom plate 16.Acted on simultaneously in each transition block 12 by the pulling to bottom plate 16, so as to balanced drive Y-axis
Sliding block 11 slides along Y-axis line rail 2.
In some embodiments, extend a fixed support arm on lathe bed base 1, the outer end of the fixed support arm rotates
Servo-actuated support arm 4 for support works platform 3 is installed, the servo-actuated support arm 4 includes the Support large arm of head and the tail rotation connection
40th, support forearm 41, the outer end of the support forearm 41 is movably installed in the bottom of workbench 3, and support the outer end of forearm 41 with
Butterfly spring 42 is installed between workbench 3.Disk spring also known as Belleville spring washer, it is with metal blank or forging and stamping base
Expect the washer type spring of truncated cone tee section formed.The rotation of the servo-actuated all parts of support arm 4 all preferably by rotating shaft connection come
Realize, Support large arm 40, support forearm 41 can be in levels to workbench 3 is followed in Arbitrary Rotation, in support works platform 3
While without limitation on its motion, butterfly spring 42 plays the effect of off-load, and the stationarity of the motion of workbench 3 is effectively ensured.
Vertical machining centre after improvement removes the saddle of traditional vertical machining center, reduces because homologous series are different
The change of saddle that specification type is brought, module generalization that can be bigger, as long as that is, hyperphoric length of workbench 3 and X-axis line rail 5 are grown
Degree can realizes the increasing of X-axis stroke, and the type of homologous series different size can simplify design.Vertical machining centre does not pass
The weight of system saddle, the dynamic property of machine tool movement is improved, and is more prone to improve the dynamic of interpolation curved surface
Can, no saddle reduces the load of Y-axis so that its dynamic property is improved simultaneously.Vertical machining centre cost drop simultaneously
It is low, the trueness error that saddle Zona transformans itself comes is reduced, and saddle difficult processing is avoided, process bad influence machine tool accuracy
Problem.In addition, the vertical machining centre without saddle can realize that X, Y-axis do right-angled intersection campaign, workbench 3 can reduce, side
Just clamping workpiece, hommization operation is more met, and integrated machine bed height can reduce, and so as to which lathe center of gravity reduces, reduce machine
The possibility of vibration is produced during bed processing, improves machining accuracy.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, for this
For the technical staff in field, the utility model can have various changes, combination and change.It is all it is of the present utility model spirit and
Within principle, any modification, equivalent substitution and improvements made etc., should be included in right of the present utility model it
It is interior.
