Abstract
The utility model relates to a double-action driving device, which comprises a hollow worm and a worm wheel, wherein, the hollow worm and the worm wheel are arranged in a machine casing body. The utility model is characterized in that a machine frame is provided with a driving screw rod which downwards faces the worm, and the driving screw rod is connected with a sliding sleeve with internal threads; the upper part of the worm which threads out of a machine casing is provided with a driving key which is arranged in a keyway at the inner wall of the lower part of the sliding sleeve; the inner part of the worm body is provided with a long pin; a positioning table shoulder of the upper end part of the long pin is positioned at the upper side of a space ring at the middle part of the sliding sleeve, and the lower end part of the long pin can thread out via a through hole on a bottom plate of the machine casing; an outer supporting sleeve at the periphery of the screw rod is provided with a positioning assembly for the sliding sleeve moving up and down; after driving the long pin to do axial displacement, the mechanism drives the worm and the worm wheel to rotate.
Description
The utility model relates to a kind of double-action driving mechanism.
Existing mechanical transmission mechanism just plays single transmission of movement effect usually, as speed-changing gear box, the rotating speed of input end can be become the high rotating speed or the slow-speed of revolution of output terminal, connecting rod and for example, and it just becomes to-and-fro motion with rotation.Yet along with the raising that people require automation, single mechanical transmission mechanism can't adapt to requirements of one's work in the electromechanical assembly that some automaticities are had relatively high expectations.
The purpose of this utility model is that a kind of double-action driving mechanism will be provided, when its when initiatively screw rod begins forward and backward, this mechanism can order about one earlier and have strong market potential and do axial displacement, then, drives worm screw again, the work of worm drive part.
The utility model is to constitute like this, it comprises hollow worm screw and the worm drive part of being located in the frame lower engine housing, it is characterized in that: the top of worm screw passes casing, the frame top is provided with the active screw rod that faces worm screw downwards, initiatively be connected with the sliding sleeve that upper inside wall has internal thread on the screw rod, the worm screw upper face is provided with the driving key that places in the sliding sleeve lower inner wall keyway, being provided with one in the worm body has strong market potential, the locating shoulder of its upper end portion is positioned at the upper side of sliding sleeve middle part spacer ring, the underpart can pass by the through hole on chassis backplane, is provided with sliding sleeve up-downgoing limit assembly with the outer bearing sleeve that is connected to the screw rod periphery.
The utility model is owing to be connected with the sliding sleeve with internal thread on the active screw rod, therefore, when the active screw rod begins clockwise and anticlockwise, but these sliding sleeve upstream or downstream meanwhile drive the have strong market potential upstream or downstream of spring in sleeve body; In case sliding sleeve up (or descending) is to contacting with up (or descending) limit assembly on the outer bearing sleeve of active screw rod, sliding sleeve follows just initiatively that screw rod rotates, simultaneously again through the keyway of its underpart inwall and driving key drives worm screw and worm gear rotates.Than existing single mechanical transmission mechanism, the utility model has compact structure in the application of dynamo-electric gear, the remarkable advantage of a machine double-action (promptly successively externally realizing two kinds of mechanical transmission effects).
Below in conjunction with drawings and Examples the utility model is specifically described.
Fig. 1 is embodiment's organigram.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the B-B sectional view of Fig. 2.
With reference to accompanying drawing, it comprises hollow worm screw 3 and worm gear 4 driving components of being located in the frame 1 lower casing body 2 the utility model, it is characterized in that: the top of worm screw passes casing, the frame top is provided with the active screw rod 5 that faces worm screw downwards, initiatively be connected with the sliding sleeve 6 that upper inside wall has internal thread on the screw rod, the worm screw upper face is provided with the driving key 7 that places in the sliding sleeve lower inner wall keyway, be provided with one in the worm body and have strong market potential 8, the locating shoulder 9 of its upper end portion is positioned at the upper side of sliding sleeve middle part spacer ring 10, the underpart can pass by the through hole on chassis backplane, and the outer bearing sleeve 11 that is fixed in the screw rod periphery is provided with sliding sleeve up-downgoing limit assembly 12,13.
An end of lower casing body is stretched out in above-mentioned rotating shaft with worm gear, is connected with runner 14.
Above-mentioned active screw rod is a cored screw, is provided with the stage clip 15 that acts on the upper end portion of having strong market potential in the cored screw, to prevent to have strong market potential play up and down.
Sliding sleeve limit assembly on the above-mentioned outer bearing sleeve is with the top board 12 of screw rod axle journal Joint and is positioned at the supporting ring 13 of outer bearing sleeve lower internal edge in order to supporting sliding sleeve upper end outer rim shoulder 17.The sliding sleeve periphery is provided with the supporting sleeve 16 that is connected on the lower casing body, matches with supporting ring on the outer bearing sleeve in the supporting sleeve upper-end surface.
In order to improve the relative movement between outer bearing sleeve and sliding sleeve and the supporting sleeve surface of contact, be laid with steel ball 18 on the downside of outer bearing sleeve top board, also be laid with steel ball 19 on the upper and lower side of outer bearing sleeve supporting ring.
The utility model is novel, and is reasonable in design, it apply the modernization that will further promote electromechanical equipment.
