Abstract

The invention relates to the technical field of wire cutting machines, in particular to a lead screw. The lead screw comprises an inner column, a threaded hole, an outer column, a bolt, a sheath, an oil nozzle and an oil pipe, wherein the threaded hole is formed in the inner column; the inner column and the outer column are fixedly connected through the bolt; the sheath is arranged on the outer column; the oil nozzle is arranged at the lower end of the outer column; the oil pipe is arranged on one side of the interior of the outer column; the oil nozzle is communicated with the oil pipe; a limiting plate is arranged at the lower part of the interior of the outer column; the height of the position, arranged inside the outer column, of the limiting plate is larger than that of the oil nozzle. The lead screw is simple, compact and reasonable in structure, convenient and quick to assemble, and reliable in connection, and can be maintained at any time; the phenomenon that the lead screw and a nut are corroded, locked and scrapped is thoroughly solved, the service life of the lead screw is prolonged, a user can adjust the length of the lead screw as required, the working reliability of the wire cutting machines is greatly improved, and the lead screw is easy to use and popularize.

Description

technical field [0001] The invention relates to the technical field of a wire cutting machine, in particular to a screw rod. Background technique [0002] It is difficult to maintain the screw rod of the existing wire cutting machine at any time. The phenomenon of rusting, jamming and scrapping of the screw rod and the screw nut often occurs, which shortens the service life of the screw rod. It is difficult for the user to adjust the length of the screw rod according to the needs, which greatly reduces the Improve the reliability of the wire cutting machine. Contents of the invention [0003] In order to overcome the shortcomings of the existing screw rods such as short service life, single length and low working reliability, the invention provides a screw rod. [0004] The technical solution adopted by the present invention to solve the technical problem is: a screw rod, including an inner column, a screw hole, an outer column, a bolt, a sheath, a nozzle and an oil pipe,...
