Abstract
An electric threaded transmission type stopper of the present invention is characterized by comprising an outer sleeve, wherein the outer sleeve sleeves an inner sleeve, a screw is arranged inside the inner sleeve, and the inner sleeve is equipped with a guide keyway; a motor arranged at one end of the outer sleeve and connected with the screw; and a guide pin matching the guide keyway and arranged in the middle of the outer sleeve. The beneficial effects of the present invention are that: the inner sleeve is arranged inside the outer sleeve, a guide sleeve is arranged between the inner and outer sleeves, the screw is arranged inside the inner sleeve, the motor is arranged at one side of the outer sleeve, and an output shaft of the motor is fixedly connected with the screw; by the threaded transmission, the adjustment and the operation are convenient; the structure is simple and compact, and the supporting is reliable; the parts are simple, the processing is convenient, and the manufacturability is strong.
Description
Technical field
The present invention relates to stopping means technical field, particularly relate to a kind of electronic screw-driven formula stop.
Background technology
In modern project machinery, often need to carry out spacing to the mechanism of a certain motion, the scope preventing from motion from exceeding system can bear, also motion is played to supporting and the effect of protection simultaneously.In practice, the solid block that general employing is fixed is used as this stopping means, this limit device structure is simple, but is not easy to regulate, and some adopts steel ball spiral stop, this with regulating, but inconvenient operation, very high to matching requirements, and complex structure, be not easy to processing, manufacturability is poor.
Summary of the invention
For the weak point existed in the problems referred to above, the invention provides a kind of electronic screw-driven formula stop.
For achieving the above object, the invention provides a kind of electronic screw-driven formula stop, comprising:
Outer sleeve, described outer sleeve internal sleeve is equipped with inner sleeve, is provided with screw rod, described inner sleeve has guide key groove in described inner sleeve inside;
Motor, it is arranged on described outer sleeve one end and is connected with described screw rod;
In the middle of described outer sleeve, the guide finger matched with described guide key groove is installed.
Improve further as the present invention, described outer sleeve side is welded with flange, and door nut is arranged on the other end of described outer sleeve.
Improve further as the present invention, manually dish is installed by bolt in described inner sleeve one end.
Improve further as the present invention, between described inner sleeve and described outer sleeve, fairlead is installed.
Improve further as the present invention, described door nut interior is equipped with sealing ring.
Improve further as the present invention, the described inner sleeve other end is fixed by screw and transmission nut.
Improve further as the present invention, described motor and described screw rod are fixed by lining and locking nut.
Beneficial effect of the present invention is: sleeve inner installs inner sleeve outside, and installs fairlead between, and inner sleeve inside is provided with screw rod, and motor is arranged on the side of outer sleeve, and the output shaft of motor is fixedly connected with screw rod; Adopt screw-driven, be convenient to regulate, easy to operate; Simple and compact for structure, support reliable; Part is simple, and be convenient to processing, manufacturability is strong.
Accompanying drawing explanation
Fig. 1 is that profile regained by a kind of electronic screw-driven formula stop of the present invention;
Fig. 2 is that a kind of electronic screw-driven formula stop of the present invention stretches out profile.
In figure: 1, inner sleeve; 2, manually coil; 3, sealing ring; 4, door nut; 5, ring flange; 6, fairlead; 7, outer sleeve; 8, guide finger; 9, screw rod; 10, transmission nut; 11, screw; 12, lining; 13, locking nut; 14, motor.
Embodiment
As shown in Figure 1-2, one described in the embodiment of the present invention electronic screw-driven formula stop, comprising: inner sleeve 1, manually coil 2, sealing ring 3, door nut 4, ring flange 5, fairlead 6, outer sleeve 7, guide finger 8, screw rod 9, transmission nut 10, screw 11, lining 12, locking nut 13, motor 14.Outer sleeve 7 and ring flange 5 weld together, and one end mounted motor 14 of outer sleeve 7, the other end is sealed by door nut 4, and sealing ring 3 is equipped with in door nut 4 inside.The centre of outer sleeve 7 is provided with guide finger 8, and guide finger 8 matches with the guide key groove on inner sleeve 1, when guide finger 8 inserts guide key groove, can prevent inner sleeve from rotating.The output shaft of motor 14 and one end of screw rod 9 link together, and the inside of outer sleeve 7 is fixed on by lining 12 and locking nut 13, screw rod 9 is provided with transmission nut 10, transmission nut 10 is fixed together by screw 11 with one end of inner sleeve 1, be provided with fairlead 6 between the centre of inner sleeve 1 and outer sleeve 7, ensure that inner sleeve can stretch smoothly, the other end of inner sleeve 1 is spirally connected and sets about Moving plate 2, this end face of inner sleeve 1 passes through frame, as spacing supporting surface.Under automatic mode, guide finger 8 inserts, and drives screw rod 9 to rotate by motor 14, then it is movable to order about inner sleeve by transmission nut 10, completes regulatory function.Under manual mode, guide finger 8 is extracted out, direct rotation manual dish 2, orders about the flexible of inner sleeve 1, realizes regulatory function.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
