Abstract
The invention provides a method for machining a pull-rod nut of a hydraulic oil cylinder. The machining method comprises the following steps of: fixing a fixed die on a machining table of a lathe, and fixing a fixed clamping seat on one side of a cover die on the fixed die; embedding a cushioning sleeve in the pull-rod nut; embedding the pull-rod nut on the cover die on one side of the fixed die; compressing a rotating die on the other side of the pull-rod nut, and locking; and allowing a fixing bolt to pass through a sliding chute of the fixed clamping seat to ensure that the fixing bolt is compressed on a turned spiral surface of the pull-rod nut and is then locked, and turning the spiral surface of the pull-rod nut. By the method, pull-rod nuts with different outer diameters and different inner diameters can be machined by replacing fixing bolts with different spiral surface clamping positions and cushioning sleeves with different thicknesses; and the method is high in machining speed and accurate in positioning.
Description
Technical field
The present invention relates to hydraulic jack manufacturing technology field, refer in particular to a kind of processing method of hydraulic jack pull-rod nut.
Background technology
Hydraulic jack is made up of cylinder barrel, end cap, piston, piston rod and pull-rod nut and seal etc., and cylinder interior is divided into two parts by piston, logical respectively oilhole.Because the compression ratio of liquid is very little; When one of them oilhole oil-feed, the hydraulic oil that gets into oil cylinder forces the cylinder bar upwards because the reason of individual event valve can not fall back again; Along with hydraulic oil constantly gets into hydraulic cylinder; Constantly rise like this, just open hydraulic valve when fall, make hydraulic oil get back to fuel tank.Having now when the processing pull rod nut, all is to adopt broaching---right boring---grinding three part operations to process, and adds man-hour, has the spiral surface location difficulty, and processing back variable thickness causes, is difficult to balance, and grinding is got up also very inconvenient.
Summary of the invention

Third step: will fill up fixed cover and be embedded in the pull-rod nut;
The 4th step: the pull-rod nut that will be embedded with the fixed cover of pad is nested on the cover die of fixed die one side;
The 5th step: rotating mould is pressed on the pull-rod nut opposite side, and through stationary barrier and hold-down nut locking;
The 6th step: pull-rod nut upper end car is gone out a spiral surface through lathe;
The 7th step: rotate rotating mould, the spiral surface that car is gone out rotates to the direction of Fixing clamp-seat;
The 8th step: after gim peg being passed the chute of Fixing clamp-seat the spiral surface screens of inclination is pressed on the good spiral surface of pull-rod nut car, locking positions pull-rod nut;
The 9th step: repeat other spiral surface that the 6th to the 8th step car goes out pull-rod nut and get final product.
Through changing the gim peg of different spiral surface screens, can process the pull-rod nut of various outer diameter.
Pad through changing different-thickness overlaps surely, can process the pull-rod nut of different inner diameters.
Accomplish the processing unit (plant) of above-mentioned said method; It includes fixed die; Both sides, fixed die lower end are provided with the pressing plate groove, and on the machine table of pressing plate groove through pressing plate assembling lathe, fixed die one side sidewall stretches out and is formed with a screw rod; The screw rod that is positioned at fixed die one side is provided with cover die, and pull-rod nut is nested on the cover die; Rotating mould is enclosed within on the screw rod, and the one of which end is pressed on the pull-rod nut, and the other end is through stationary barrier and hold-down nut locking, and machine table is provided with the Fixing clamp-seat that matches with cover die.
Be provided with gim peg in the described Fixing clamp-seat, gim peg is assemblied in the chute of Fixing clamp-seat, and gim peg one end is provided with the spiral surface screens of inclination, and this spiral surface screens matches with cover die.
The cross section of described cover die is a stairstepping, and its bigger cascaded surface is provided with a recessing breach.
The less cascaded surface of described cover die is provided with the fixed cover of pad.
The present invention is after having adopted such scheme, and the gim peg through changing different spiral surface screens and the pad of different-thickness overlap surely,, can process the pull-rod nut of various outer diameter and different inner diameters.And the process velocity of this programme is fast, the location is accurate.
