Description
Technical field
This utility model relates to the intermediate active supporting of long screw in a kind of machine driving, belongs to mechanical-hydraulic Composite Transmission
Device.
Background technology
In lathe long screw transmission, the most flexible deformation in the middle of screw mandrel, various machineries, electromechanical structure group
Synthesis frame support bracket, feed screw nut by time automatic or manual operation dodge.
Summary of the invention
Supporting for more preferably realizing the intermediate active of long screw in machine driving, this utility model provides a kind of mechanical-hydraulic control
Mechanism processed, this hydraulic control reliable from avoiding-type holder for screw rod accurate positioning, by hydraulic pressure programme-control without artificial behaviour
Make.
The technical solution of the utility model is: in machine driving, the hydraulic pressure of long screw intermediate active supporting is from avoiding-type
Holder for screw rod, including rest pad, piston shaft, hydraulic cylinder, travel switch, stroke collision block, positioning groove plate, pipe joint, described
Rest pad is connected by screw in piston shaft end, and rest pad contacts with the cylindrical being supported by long screw and bears sliding friction and prop up
Making use, described hydraulic cylinder is arranged on basic machine, and piston shaft can move back and forth in hydraulic cylinder, described pipe
Joint has two, is respectively communicated with the both sides of the piston portion of piston shaft, and hydraulic oil is passed through piston one end through pipe joint, and piston shaft is stretched
Going out and support screw mandrel, hydraulic oil is passed through the piston other end through pipe joint, in piston shaft retraction hydraulic cylinder, and the movement nut on screw mandrel
By bearing position, described travel switch is assemblied in movement nut, and stroke collision block and positioning groove plate are fixed on basic machine
On.
During application, piston shaft stretches out hydraulic cylinder under hydraulic pressure effect, and rest pad holds screw mandrel, when nut motion connects
During nearly rest pad, the stroke collision block pressure that travel switch is positioned on frid, travel switch sends signal, and hydraulic control is anti-
To, in piston shaft and rest pad retraction hydraulic cylinder, after nut moves away from rest pad, travel switch is sent out after departing from stroke collision block
Going out signal, hydraulic control commutates, and piston shaft stretches out.
Accompanying drawing explanation
Accompanying drawing 1 is that this utility model hydraulic pressure is from dodging holder for screw rod structural scheme of mechanism.
Detailed description of the invention
Seeing accompanying drawing 1, this utility model provides a kind of hydraulic pressure from dodging holder for screw rod, including rest pad 1, piston shaft 2, liquid
Cylinder pressure body 3, travel switch 4, stroke collision block 5, positioning groove plate 6, pipe joint 7, pipe joint 8.
Described rest pad 1 is connected by screw in piston shaft 2 end, and rest pad 1 and the cylindrical being supported by long screw connect
Touching and bear sliding friction and supporting role, described hydraulic cylinder 3 is arranged on basic machine, and piston shaft 2 can be at hydraulic cylinder
Moving back and forth in body 3, when being passed through hydraulic pressure oil in described pipe joint 8, piston shaft 2 Extension support screw mandrel, described pipe connects
When being passed through hydraulic pressure oil in 7, piston shaft 2 is retracted in hydraulic cylinder 3,
Described travel switch 4 is assemblied in movement nut, and stroke collision block 5 and positioning groove plate 6 are fixed on basic machine.
