Detailed Description
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
The invention is described in further detail below with reference to the figures and specific examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1-2, the present application performs oil path processing on the head of an inner cavity 2 of a conventional electric push rod piston rod, and adds an inner cavity oil inlet 1 for filling new lubricating oil; meanwhile, a copper nut 8 is processed, and an inner outer cavity oil through hole 4 and an outer cavity front and rear cavity oil through hole 7 are added and are respectively used for flowing of lubricating oil in an inner cavity of the piston rod and flowing of the lubricating oil in the front and rear cavities; the front and the back of the push rod shell cavity are provided with an oil discharge hole front oil discharge hole 5 and a back oil discharge hole 10 which are used for discharging old oil. The copper nut 8 is additionally provided with the inner cavity oil through hole 4, the outer cavity oil through hole 7, the front cavity oil through hole and the rear cavity oil through hole, and smooth flowing of lubricating oil is guaranteed.
Wherein, the inner and outer chamber oil through hole 4 that copper nut 8 increases sets up directly over the screw rod 6, has guaranteed that the lubricating oil that the inner chamber flowed out flows on to the screw rod, has improved lubricated effect.
Working principle of oil circuit
1. Preparation before filling lubricating oil:
and opening the front oil discharge hole 5 and the rear oil discharge hole 10 of the oil discharge hole, controlling the electric push rod to perform telescopic motion, discharging part of old oil in the cavity of the push rod shell, and keeping the electric push rod in a push-out state before lubricating oil is filled.
2. Filling of lubricating oil:
lubricating oil is filled into the inner cavity 2 from the inner cavity oil inlet hole 1 through the oil filling nozzle, and the filling is stopped when the filled lubricating oil reaches the expected capacity;
lubricating oil adds and annotates the back, withdraw the push rod, make the push rod withdrawal, along with the motor is rotatory, it is rotatory to drive screw rod 6 through the speed reducer, copper nut 8 on the screw rod 6 is along with the rotation of screw rod 6, advance to the screw rod 6 root, simultaneously screw rod 6 enters into the part of inner chamber 2 also more and more, the lubricating oil of inner chamber 2 is along with the extrusion, it leads to oilhole 4 and gets into outer shell cavity back cavity 9 through interior outer chamber, simultaneously along with copper nut 8 to the motion of screw rod 6 root, oil drain hole 10 after some old oil is extruded by new oil, close preceding oil drain hole 5 and back oil drain hole 10, the lubricating oil filling is accomplished.
3. Lubricating oil running track of push rod in normal working state
