Abstract
The invention relates to a novel mechanical transmission mechanism which is characterized in that a rack is fixedly installed on a base, and a rack is fixedly installed at a sliding threaded sleeve by a screw; after the rack is fixedly installed at the sliding threaded sleeve, a sliding bearing part is installed in an inner hole of the rack; one part of a rotating limit key is fixed at the rack, and the head part of one end is inlaid in a guiding groove on the excircle of the sliding threaded sleeve; a forward driving servo motor is fixedly installed at the side surface of the rack, and an output shaft of the forward driving servo motor is fixedly provided with a gear wheel by the key; and a leading screw is installed in the sliding threaded sleeve by the internal thread of the sliding threaded sleeve. A left axial positioning support and a right axial positioning support are oppositely fixedly installed on the base. A boss corresponding to a leading screw guiding groove is manufactured in an inner hole of a large synchronization belt pulley, and the corresponding boss is inlaid in the leading screw guiding groove. The large synchronization belt pulley is connected with a small synchronization belt pulley by a synchronous belt, and a connector is installed at the proper position of the end part of the leading screw.
Description
Technical field
The present invention relates to a kind of driving mechanism, particularly a kind of novel mechanical driving mechanism belongs to mechanical transmission and technical field of automation.
Background technique
In mechanical manufacturing field, often use the motion that rotates simultaneously and advance, such as, the oil groove of the screw type on the processing bearing shell, make screw thread and also have in other a few thing, all use rotation and the compound motion that advances, at present, realize the mechanism of these motions, all accuse mechanically operated mode and realize that not only have complex structure, cost is higher, the defective that rate of fault is higher, simultaneously, this composite-motion mechanism generally immobilizes, and is merely able to realize a kind of or a few the motion of kinematic parameter, its flexibility degree is lower, once the change of kinematic parameter then must redesign manufacturing, so, not only use trouble, also have influence on the cycle of production simultaneously.
Summary of the invention
The objective of the invention is to: a kind of novel mechanical driving mechanism is provided, this novel mechanical driving mechanism, characteristics with higher flexibility satisfy in the machine industry and in the other industry, to the rotation of different motion parameter and the demand of the composite-motion mechanism that advances.
The present invention realizes that the technological scheme that above-mentioned purpose adopts is: frame is fixed on above the base, tooth bar is installed and fixed by screw or other mode and slip swivel nut, after tooth bar and slip swivel nut are installed and fixed into one, above-mentioned parts are installed in the endoporus of frame by sliding bearing, a rotary stopper key part is fixed with frame, in the guiding groove on the cylindrical of the head embedding slip swivel nut of one end, side in frame, install and fix the forward drive actuating motor, the axis that wherein guarantees the output shaft of forward drive actuating motor be in tooth bar above, and it is vertical with the direction of advance of tooth bar, install and fix gear by key on the output shaft with the forward drive actuating motor, wheel and rack forms meshing relation, with the internal thread of leading screw by the slip swivel nut, be installed in the internal thread of slip swivel nut, both form the screw-thread fit relation, with left axially locating support and right axially locating support relatively be fixed on base above, big synchronous pulley is fixed between left axially locating support and the right axially locating support by two plane bearings about it, in advance on the cylindrical of leading screw, produce two or a leading screw guiding groove along its axial direction, produce and the corresponding boss of leading screw guiding groove in the endoporus of big synchronous pulley, corresponding boss is embedded in the leading screw guiding groove, the output shaft of small synchronous pulley and rotary drive motor is installed and fixed, with synchronous band big synchronous pulley and small synchronous pulley are coupled together, make both form meshing relation, connector is installed appropriate location, leading screw end.
Beneficial effect: a kind of any rotation of the present invention and the composite-motion mechanism that advances, since its rotation with the relevant parameter that advances fully by actuating motor by corresponding program control, so, advantage with higher flexibility, can satisfy in the machine industry and in the other industry, to the rotation of different motion parameter and the demand of the composite-motion mechanism that advances, overcome existing composite-motion mechanism, be merely able to realize a kind of or a few the motion of kinematic parameter, its flexibility degree is lower, once the change of kinematic parameter then must be made in redesign, not only use trouble, also have influence on the defective of manufacture cycle simultaneously.
