The utility model content
For overcoming above-mentioned shortcoming, the utility model purpose provides a kind of thread delivering machine structure of wire cutting machine tool, leading screw when it can solve the wire cutting machine bed operating under prerequisite cheaply and the good lubrication problem between the nut.
The technical solution of the utility model is: a kind of thread delivering machine structure of wire cutting machine tool, it mainly comprises frame, motor and is used for the rolled thread tube of rolled electrode silk, the rolled thread tube is rotationally connected with on the frame by a main shaft, one end of main shaft is connecting the clutch end of motor, and the rolled thread tube is driven to rotate under the torsion of motor.This thread delivering machine structure also comprises gearbox, leading screw and nut, and the input of gearbox is connecting the other end of main shaft, and an end of leading screw is connecting the output of gearbox, leading screw also with nut mutually threaded engagement connect, nut is connected with frame.Also have an oil ring that is enclosed within above it on leading screw, the part of oil ring is immersed in the oil groove.During the running of rolled thread tube, the transmission of process gearbox makes leading screw rotate, and rotates round leading screw thereby drive oil ring, makes that oil ring constantly takes the oil in the oil groove to leading screw and nut gets on, and reaches good lubricating effect.
Further, gearbox comprises the gear that multistage transmission successively cooperates.By the multi-stage gear in gearbox transmission successively, make leading screw rotate with proper speed, this easy realization simple in structure, and cost is lower.
Preferably, second gear that has first gear in the gearbox, is meshed with first gear, the 3rd gear that is connected with the second gear same axis, the 4th gear that is meshed with the 3rd gear, the main shaft of the rotating shaft of first gear and rolled thread tube links by a bearing, and the rotating shaft of the 4th gear is connected with leading screw.Carry out twice speed by first gear and second gear meshing, the 3rd gear and the 4th gear meshing and change, make leading screw finally rotate with appropriate rotating speed.
Compared with prior art, the utility model has the advantages that: pick oil in the oil groove by being enclosed within oil ring on the leading screw, and oil is delivered on leading screw and the nut continuously, to play good lubrication, can prolong the life cycle of leading screw and nut greatly, improve the service life of lathe and the stability of machine mass, and this lubricating system is simple in structure, operation is very easy, and cost is also very low, is beneficial in this area and promotes.
