Abstract
The utility model discloses a screw rod mechanism for a numerically-controlled machine tool. The screw rod mechanism for the numerically-controlled machine tool comprises a screw rod and a nut, a tail seat is arranged at the front end of the screw rod, a front seat is arranged at the front end of the screw rod, the nut is provided with a flange plate, and inserting pipes are arranged on the rear side of the front seat, the front side of the tail seat and the two sides of the nut. The screw rod is sleeved with two telescopic corrugated pipes, the two telescopic corrugated pipes are located on the two sides of the nut respectively, and the two ends of each telescopic corrugated pipe are connected with the corresponding inserting pipes in an inserted mode and are clamped and fastened through clamps. The two sides of the screw rod are respectively provided with a guide wire, and via holes allowing the guide wires to pass through are formed in the wall parts at wave crests of the two telescopic corrugated pipes and the flange plate. The screw rod mechanism for the numerically-controlled machine tool is simple in structure and convenient to mount and has a good protection effect on the screw rod, dust, scraps and other impurities can be prevented from entering threads, the precision and the durability of the screw rod mechanism can be guaranteed, and therefore the screw rod mechanism for the numerically-controlled machine tool has remarkable practicability.
Description
Technical field
The utility model relates to a kind of lathe accessory, relates in particular to a kind of Digit Control Machine Tool screw mechanism.
Background technology
Screw mechanism is to convert rotation to straight-line a kind of mechanical device, and in Digit Control Machine Tool field, application is very wide.Screw mechanism mainly forms by screw mandrel with the nut of its threaded engagement, outside when existing screw mechanism is installed, screw mandrel part is mostly exposed to, lack safeguard procedures, and meeting produces a large amount of chips or mud dirt in lathe operation process, once stick to the accuracy that can affect both cooperations in the screw thread of screw mandrel and nut, accelerated its rate of wear, these impurity are difficult to thoroughly clean out simultaneously.In addition, also there are in scheme the means that propose to be nested with pillar on screw mandrel play the effect of protection, but in the time that screw mandrel is longer, this pillar adding is often bending and too tight with screw mandrel laminating, thereby affect the conformability of nut and screw mandrel, and sleeve pipe can not effectively be sealed in screw mandrel in the environment of a relative closure, and protective action is to be improved.
Utility model content
For overcoming above-mentioned technical problem, it is a kind of simple in structure, easy for installation that the utility model provides, and long service life has better protective, is conducive to ensure the Digit Control Machine Tool screw mechanism of long-time steady operation.
For realizing above-mentioned technical purpose, the utility model adopts following scheme: a kind of Digit Control Machine Tool screw mechanism, comprise screw mandrel and the nut with its threaded engagement, the front end of screw mandrel is provided with tailstock, front end is provided with front stall, nut is provided with flanged plate, it is characterized in that: described front stall rear side, the front side of tailstock and the both sides of nut are equipped with an insertion pipe; Two expansion corrugated pipes are nested with on screw mandrel, and lay respectively at the both sides of nut, the two ends of expansion corrugated pipe respectively with corresponding insertion pipe socket connection, and fix by clip; Described screw mandrel both sides are respectively provided with a seal wire, the two ends of seal wire are fixed by front stall and tailstock respectively, the wall portion at the crest place of two described expansion corrugated pipes and flanged plate are provided with the via hole passing for seal wire, two expansion corrugated pipes can stretch along two seal wires, and flanged plate can move along seal wire.
The utlity model has following beneficial effect: because screw mandrel is equipped with two expansion corrugated pipes outward, and lay respectively at the both sides of nut, can be with the moving and stretch of nut, and then can prevent that dust, chip from entering in screw thread, ensure accuracy and the durability of screw mechanism; Because the two ends of expansion corrugated pipe are fixed by insertion pipe and clip, therefore two ends are fixing comparatively firm, long service life, moves comparatively stable; Because the both sides of screw mandrel are provided with seal wire, can be two expansion corrugated pipes guide effect and certain support force be provided, avoid expansion corrugated pipe bending and with screw mandrel laminating, guarantee that both remain fixing spacing, avoid affecting nut and wire rod thread fiting effect.The utility model is simple in structure, easy for installation, and screw mandrel is had to good protection effect, can avoid the impurity such as dust chip to enter in screw thread, is conducive to ensure screw mechanism accuracy and durability, and then has significant practicality.
