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
The present invention relates to a kind of technical field of linear cutting machine, especially a kind of screw mandrel.
Background technique
Existing linear cutting machine screw mandrel is difficult to maintain at any time screw mandrel, often there is the phenomenon that screw mandrel and screw corrosion are stuck and scrap, shortened the working life of screw mandrel, user is difficult to regulate as required the length of screw mandrel, greatly reduces the reliability of linear cutting machine work.
Summary of the invention
In order to overcome the deficiency that existing screw mandrel working life is short, length is single and functional reliability is low, the invention provides a kind of screw mandrel.
The technical solution adopted for the present invention to solve the technical problems is: a kind of screw mandrel, comprise inner prop, screw, column jacket, bolt, sheath, oil nozzle and oil pipe, inner prop is provided with screw, inner prop and column jacket are bolted to connection, column jacket is provided with sheath, column jacket lower end is provided with oil nozzle, and the inner side of column jacket is provided with oil pipe, and oil nozzle is communicated with oil pipe.
According to another embodiment of the invention, further comprise that in column jacket, below is provided with limiting board, the height of limiting board in column jacket is higher than the height of oil nozzle.
The invention has the beneficial effects as follows, this screw structure is simple, compact and reasonable, easy to assembly quick, connect reliably, can maintain at any time screw mandrel, thoroughly avoid the phenomenon that screw mandrel and screw corrosion are stuck and scrap, extended the working life of screw mandrel, user can regulate the length of screw mandrel as required, has greatly improved the reliability of linear cutting machine work, is easy to use promote.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
1. inner props in figure, 2. screw, 3. column jacket, 4. bolt, 5. sheath, 6. oil nozzle, 7. oil pipe.
Embodiment
If Fig. 1 is structural representation of the present invention, a kind of screw mandrel, comprise inner prop 1, screw 2, column jacket 3, bolt 4, sheath 5, oil nozzle 6 and oil pipe 7, inner prop 1 is provided with screw 2, and inner prop 1 is fixedly connected with by bolt 4 with column jacket 3, column jacket 3 is provided with sheath 5, column jacket 3 lower ends are provided with oil nozzle 6, and the inner side of column jacket 3 is provided with oil pipe 7, and oil nozzle 6 is communicated with oil pipe 7, the interior below of column jacket 3 is provided with limiting board 8, and the height of limiting board 8 in column jacket 3 is higher than the height of oil nozzle 6.
During use, inner prop 1 is provided with screw 2, inner prop 1 is fixedly connected with by bolt 4 with column jacket 3, user can be at any time according to the length that need to regulate screw mandrel of oneself, column jacket 3 is provided with sheath 5, guarantee that screw mandrel outside is not fragile, column jacket 3 lower ends are provided with oil nozzle 6, the inner side of column jacket 3 is provided with oil pipe 7, oil nozzle 6 is communicated with oil pipe 7, can to screw mandrel, be lubricated at any time, and the interior below of column jacket 3 is provided with limiting board 8, the height of limiting board 8 in column jacket 3, higher than the height of oil nozzle 6, avoided the damage of 1 pair of oil nozzle 6 of inner prop.This screw structure is simple, compact and reasonable, easy to assembly quick, connect reliable, can maintain at any time screw mandrel, thoroughly avoid the phenomenon that screw mandrel and screw corrosion are stuck and scrap, extended the working life of screw mandrel, user can regulate the length of screw mandrel as required, greatly improved the reliability of linear cutting machine work, be easy to use and promote.
