Along with becoming better and approaching perfection day by day of gantry numerical control milling machine technology, require that the stability of people to engineering goods is more and more higher.As everyone knows, single-screw mandrel transmission, main shaft, away from crossbeam, does not stress, higher to counterweight requirements, very large to lathe balance influence, and the double lead synchronization structure of split assembling usually affects the rigidity of servo-drive system, and position deviation can elastic deformation.
Utility model content
The utility model provides that a kind of balance is good, the simple numerical control gantry machine tool of process and assemble and Z axis double lead monoblock type feed mechanism thereof, to solve the problem of prior art poor rigidity, the distortion of position deviation influence elastane.
For solving the problem, as an aspect of the present utility model, providing a kind of Z axis double lead monoblock type feed mechanism of numerical control gantry machine tool, comprising: horizontally disposed crossbeam, crossbeam is provided with the first guide rail of level; Saddle, saddle is slidably mounted on the first guide rail; Two parallel the second guide rails, the second guide rail is vertically arranged on saddle; Two screw mandrels, two screw mandrels are parallel and be vertically arranged on saddle; Two slide blocks, two slide blocks are threaded correspondingly with two screw mandrels, and two slide blocks are also slidably connected correspondingly with two the second guide rails; Chief axis, is connected with two slide blocks; Main shaft, is arranged on Chief axis; Two motors, drive correspondingly with two screw mandrels respectively and are connected Chief axis in the vertical direction is moved.
Further, Z axis double lead monoblock type feed mechanism also comprises two bearing blocks, and bearing block is arranged on saddle, and the lower end of two screw mandrels is pivotably mounted in a bearing block respectively.
Further, Z axis double lead monoblock type feed mechanism also comprises two motor cabinets, two motor cabinets is separately installed with a motor.
The utility model additionally provides a kind of numerical control gantry machine tool, comprises above-mentioned Z axis double lead feed mechanism.
During work, motor in synchrony ground drives two screw mandrels to rotate, thus slide block is moved up and down along two the second guide rails, to drive Chief axis to move up and down, thus balancing counterweight mechanism when solving single-screw mandrel transmission in prior art is unstable and the double lead position deviation of Split type structure and elastic deformation affect precision and the working (machining) efficiency problem on the low side of lathe.
