Full-lubricated lifting nut

Abstract

The invention discloses a full-lubricated lifting nut, and belongs to the technical field of machine tool fittings. A lifting lead screw is screwed into a lifting nut through a thread; a pair of lubricating pipes for pouring the lifting lead screw is arranged above the lifting nut; four equal-angle long oil holes are drilled in the upper end surface of the lifting nut in an annular array form; thelengths of the long oil holes are 4 / 5 of the length of the lifting nut; a row of six equal-interval inclined oil holes is drilled on the outer side of each long oil hole on the side wall of the lifting nut; the inclined oil holes all penetrate through the back ends of the long oil holes on one side, and extend to engaged surfaces of the lifting nut and the lifting lead screw; oil plugs are arranged at the outer ends of the inclined oil holes; lubricating pipe joints are arranged at the top ends of the long oil holes on the lifting nut, and are all connected with oil incoming pipes; the lubricating pipes are also connected with the oil incoming pipes; the lubricating pipes directly pour lubricating oil on the lifting lead screw; and four lubricating pipe joints pour the lubricating oil ina gap between threaded engagement surfaces of the lifting nut and the lifting lead screw through the inclined oil holes.

Description

technical field [0001] The invention relates to a fully lubricated lifting nut, which belongs to the technical field of machine tool accessories. Background technique [0002] With the rise of shipbuilding, mining, hydropower, nuclear power and other industries, the processing diameter of large thin-walled rotary parts is developing towards large-scale. These parts are mostly regular thin-walled rotary bodies. To meet market demand, it is necessary to develop large Car to meet the processing requirements of parts. As the processing diameter of parts increases, the corresponding processing equipment vertical lathe is also getting larger and larger, and the components of the vertical lathe, such as columns and beams, are also getting larger and heavier. In the actual production process, the lifting and lowering of the beam is realized by the T-shaped screw and the screw nut. As the beam becomes heavier and heavier, the load of the lifting screw nut becomes larger and larger d...

Problems solved by technology

[0003] In order to solve the above-mentioned deficiencies in the prior art, the present invention provides a fully lubricated lifting nut, which improves the lubrication method of the lifting nut, and solves the problem of the lifting and lowering of the beam during the lifting process by fully lubricating the lifting nut. The mother wears seriously, and at the same time, it will generate large vibration and noise, which will seriously affect the accuracy of the machine tool.
