Existing, in machine tooling equipment, a large amount of screw mandrels that adopt are as transmission device, and when lathe work, screw mandrel is by driving servomotor to drive screw mandrel to rotate, and band movable slider is along screw mandrel axial-movement.In the time that screw mandrel length is longer, the transmission thrust of servomotor diminishes, easily causes screw mandrel pogo stick, affects machining accuracy.
For addressing the above problem, publication number is: the utility application of CN101462233A discloses a kind of machine tool horizontal lead screw oil lift device, it is characterized in that: hydraulic support device is positioned at screw mandrel centre position, hydraulic support device top has the roller that drags jackscrew bar, in the time of the nut seat convergence of workbench, sender is to magnetic valve, make the piston rod of oil cylinder drive roller to retract, allow nut seat cross, after nut seat is crossed after certain distance, sender, to magnetic valve, makes the piston rod of oil cylinder drive roller rise to drag jackscrew bar.This kind of screw mandrel bracing or strutting arrangement can play certain effect that prevents screw mandrel pogo stick in the time that roller is not retracted, but in the time that roller is retracted, screw mandrel lose support easily shake, pogo stick, affect machining accuracy, this kind of support device structure complexity, production, maintenance cost are high in addition.
Utility model content
In order to overcome the deficiencies in the prior art, provide a kind of can have complete in the mobile overall process of rotating nut seat support screw, prevent the bracing or strutting arrangement of screw mandrel shake.
For achieving the above object, the utility model provides a kind of screw mandrel bracing or strutting arrangement of rotating nut, comprise screw mandrel supporting mechanism and the guiding mechanism being connected with screw mandrel supporting mechanism, described guiding mechanism is arranged on pedestal and is positioned at screw mandrel below, and drive screw mandrel supporting mechanism to go up in vertical direction, lower movement, this screw mandrel supporting mechanism holds screw mandrel while moving up, while moving down, avoid the rotating nut on screw mandrel, it is characterized in that: described pedestal is provided with at least two cocainine bar supporting mechanism and guiding mechanisms, this screw mandrel supporting mechanism comprises screw mandrel back-up block and back-up block adjustment block, screw mandrel back-up block middle part has one for holding the groove of screw mandrel, and this groove opening shrinks from top to bottom gradually, back-up block adjustment block is arranged between screw mandrel back-up block and guiding mechanism, by back-up block adjustment block, the position between screw mandrel back-up block and guiding mechanism is finely tuned.
Further, guiding mechanism comprises oil cylinder and fixed mount, and described oil cylinder is installed on fixed mount, and fixed mount is fixedly connected with pedestal.
Further, guiding mechanism also comprises that one is arranged at the oil cylinder adjustment block between oil cylinder and oil cylinder fixed mount, by oil cylinder adjustment block, the position between oil cylinder and fixed mount is finely tuned.
Further, back-up block adjustment block is fixed on the end of oil cylinder piston.
Further, screw mandrel back-up block and back-up block adjustment block are bolted.
From above-mentioned to description of the present utility model, the screw mandrel bracing or strutting arrangement of the rotating nut that the utility model provides, in transmission process, many cocainines bar supporting mechanism moves up and down successively under the driving of guiding mechanism, screw mandrel is held up, avoid causing because screw mandrel is long self gravitation sagging and because of driving torque according to screw mandrel beat, the screw mandrel support device structure of the rotating nut of this kind is simple, production cost is low.
