Abstract
The utility model relates to a novel EMP lead screw, including the lead screw overcoat, install big lead screw in the lead screw overcoat, big lead screw internally mounted has a little lead screw, and jump ring and bearing are installed to the one end of big lead screw, and the lead screw adapter sleeve is installed through the lead screw guide block to the other end of big lead screw, and the lead screw spline is installed to the tip of little lead screw, the lead screw spline lies in same one end with the lead screw adapter sleeve. The utility model discloses a mode of placeing little lead screw in the big lead screw realizes the meshing of two rhizoid poles, and when the rotation, big lead screw extends toward a direction, and big lead screw passes through lead screw guide block promotion lead screw adapter sleeve and extends to another direction, has realized that the twocouese of lead screw extends, when extending the same length, and the whole length of the short silk pole that can contract.
Description
Technical field
The utility model relates to a kind of screw mandrel, specifically relates to a kind of new E MP screw mandrel, belongs to the technical field of transmission device.
Background technique
Leading screw is the transmission component that machine tool and precision optical machinery the most often use, and its major function converts rotary motion to linear motion, or torque axis is changed into axial repeated action power, has highi degree of accuracy, reversibility and high efficiency feature concurrently simultaneously.Owing to having very little surface friction drag, be widely used in various industry equipment and precision type instrument.
Existing screw mandrel can only realize single direction and extend, and need the length reaching actual demand could meet the demand of commercial Application, therefore in equipment component, the length of screw mandrel cannot meet the demand of equipment.Based on this, the present inventor have developed the screw mandrel that a kind of twocouese extends, and the utility model produces thus.
Model utility content
For the above-mentioned technical problem of prior art, the purpose of this utility model is to provide a kind of new E MP screw mandrel, achieves the function that twocouese extends, and when extending equal length, can shorten the entire length of screw mandrel.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of new E MP screw mandrel, comprise screw mandrel overcoat, in described screw mandrel overcoat, big wire role is installed, described big wire role inside is provided with minor leading screw, one end of described big wire role is provided with jump ring and bearing, the other end of big wire role is provided with screw mandrel connecting sleeve by screw mandrel guide pad, and the end of described minor leading screw is provided with screw mandrel spline, and described screw mandrel spline and screw mandrel connecting sleeve are positioned at same one end.
The joint of described big wire role and screw mandrel overcoat is provided with big wire role swivel nut, and described big wire role swivel nut is positioned at the below of bearing.
The end of described minor leading screw is provided with minor leading screw swivel nut, and the outside of described minor leading screw swivel nut is provided with swivel nut fixed block.
Screw mandrel overcoat is stretched out in the end of described minor leading screw.
The beneficial effects of the utility model are as follows:
New E MP screw mandrel of the present utility model, by assigning the mode of minor leading screw in big wire role, realize the engagement of two rhizoid bars, when rotating, big wire role extends toward a direction, and big wire role promotes screw mandrel connecting sleeve by screw mandrel guide pad and extends to another direction, and the twocouese achieving screw mandrel extends, when extending equal length, the entire length of screw mandrel can be shortened.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of Fig. 1;
Wherein, 1 be screw mandrel overcoat, 2 be big wire role, 3 be minor leading screw, 4 be jump ring, 5 be bearing, 6 be screw mandrel guide pad, 7 be screw mandrel connecting sleeve, 8 be minor leading screw swivel nut, 9 be screw mandrel spline, 10 be big wire role swivel nut, 11 for swivel nut fixed block.
Embodiment
Below in conjunction with specific embodiment, the utility model is further described, but protection domain of the present utility model is not limited to this.
As illustrated in fig. 1 and 2, new E MP screw mandrel of the present utility model, comprise screw mandrel overcoat 1, big wire role 2 is installed in screw mandrel overcoat 1, big wire role 2 inside is provided with minor leading screw 3, one end of big wire role 2 is provided with jump ring 4 and bearing 5, and big wire role 2 is provided with big wire role swivel nut 10 with the joint of screw mandrel overcoat 1, and big wire role swivel nut 10 is positioned at the below of bearing 5; Screw mandrel overcoat 1 is stretched out in the end of minor leading screw 3, and the end of minor leading screw 3 is provided with minor leading screw swivel nut 8, and the outside of minor leading screw swivel nut 8 is provided with swivel nut fixed block 11.
The other end of big wire role 2 is provided with screw mandrel connecting sleeve 7 by screw mandrel guide pad 6, and the end of minor leading screw 3 is provided with screw mandrel spline 9, and screw mandrel spline 9 and screw mandrel connecting sleeve 7 are positioned at same one end.
New E MP screw mandrel of the present utility model, by assigning the mode of minor leading screw 3 in big wire role 2, realize the engagement of two rhizoid bars, when rotating, minor leading screw 3 extends toward a direction, and big wire role 2 promotes screw mandrel connecting sleeve 7 by screw mandrel guide pad 6 and extends to another direction, and the twocouese achieving screw mandrel extends, when extending equal length, the entire length of screw mandrel can be shortened.
Above-described embodiment only illustrates inventive concept of the present utility model for explaining, but not the restriction to the utility model rights protection, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should fall into protection domain of the present utility model.
