Further, supporting seat comprises pedestal and two support rollers, and this pedestal is connected with guiding mechanism, and two support roller symmetries are installed on pedestal and the rotating shaft of two support rollers and screw mandrel are arranged in parallel.
Further, guiding mechanism comprises and drives oil cylinder and lead, and the output of this driving oil cylinder is fixedly connected with supporting seat, and lead one end is fixed on lathe, the other end and run through supporting seat.
Further, lead is provided with two, and two leads are symmetrically arranged in and drive oil cylinder both sides.
Further, limit induction device comprises induction installation and flip flop equipment, and this induction installation is installed on lathe, flip flop equipment is installed on nut seat, and when nut seat convergence supporting seat, induction installation sends control signal to guiding mechanism.
From above-mentioned, to description of the present utility model, the horizontal lead screw device of the heavy duty machine tools that the utility model provides, can offset the impact of most of gravity on horizontal lead screw, effectively prevents horizontal lead screw sagging deformation because Action of Gravity Field produces; Adopt limit induction device to control supporting seat and move, can effectively prevent supporting seat and nut seat collision, also can reduce the impact that supporting seat moves up and down on precision, screw rod transmission precision is high, job stability is strong, persistence is good.
Accompanying drawing explanation
Fig. 1 is that the utility model specific embodiment is for the horizontal screw lead apparatus structure schematic diagram of heavy duty machine tools.
The specific embodiment
Below by the specific embodiment, the utility model will be further described.
Shown in Fig. 1, a kind of horizontal lead screw device, comprise horizontally disposed screw mandrel 1, the nut seat 2 matching with screw mandrel 1, be connected with screw mandrel 1 and drive the drive motors of screw mandrel 1 rotation, also comprise that wherein screw mandrel bracing or strutting arrangement 3 comprises supporting seat, guiding mechanism and limit induction device for preventing the sagging bracing or strutting arrangement of screw mandrel 13;
Supporting seat is arranged under screw mandrel 1, comprises pedestal 31 and two support rollers 32, has pilot hole 311, two support roller 32 symmetries and be installed on the rotating shaft and the screw mandrel 1 that on pedestal 31, hold screw mandrel 1 and two support rollers 32 and be arranged in parallel on this pedestal 31;
Guiding mechanism is connected to drive supporting seat to move up and down with supporting seat, guiding mechanism comprises driving oil cylinder 33 and two leads 34, drive the output of oil cylinder 33 to be fixedly connected with pedestal 31, be used for driving pedestal 31 to move up and down, two leads 34 are symmetrically arranged in and drive oil cylinder 33 both sides, its one end is fixed on lathe, the other end is by pilot hole 311 and run through pedestal 31, and pedestal 31 can move up and down in vertical direction by lead 34 pilot holes 311;
Limit induction device is for responding to the distance between nut seat 2 and supporting seat and transmitting control signal to guiding mechanism, limit induction device comprises induction installation 35 and flip flop equipment 36, this induction installation 35 is installed on base 100, flip flop equipment 36 is installed on nut seat 2, limit induction device is arranged to when nut seat 2 convergence pedestal 31, induction installation 35 is triggered and passes on signal to driving oil cylinder 33, drives oil cylinder 33 to operate supporting seat is moved down to avoid nut seat 2.
