Abstract
The invention relates to a novel mechanical transmission mechanism. A frame is arranged and fixed on a base; a rack and a sliding screw sleeve are arranged and fixed through a screw; after the rack and the sliding screw sleeve are arranged and fixed to form a whole, the parts are arranged in an inner hole of the frame through a sliding bearing; the tail part of one end of a rotating limit key is fixed with the frame; a screw rod is arranged in the sliding screw sleeve through the internal thread of the sliding screw sleeve; a left axial positioning bracket and a right axial positioning bracket are oppositely arranged on the base; a pre-manufactured screw rod guide groove is formed on the excircle of the screw rod; a pre-manufactured boss corresponding to the screw rod guide groove is arranged in an inner hole of a large synchronous belt wheel; the corresponding boss is embedded into the screw rod guide groove; a small synchronous belt wheel and an output shaft of a rotating drive motor are arranged and fixed; the large synchronous belt wheel and the small synchronous belt wheel are connected through a synchronous belt; and a connector is arranged at the end of the screw rod.
Description
Technical field
The present invention relates to a kind of mechanical transmission 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, realize by mechanically operated mode that all 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 motion of or a few 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, have higher flexibility characteristics, satisfy in the machine industry and in the other industry, to the demand of different motion parameter rotation with the composite-motion mechanism that advances.
The present invention realizes that the technological scheme that above-mentioned purpose adopts is: a kind of novel mechanical driving mechanism, it is that frame is fixed on above the base, tooth bar is installed and fixed by screw 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, the afterbody and the frame of one end of rotary stopper key are fixed, in 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, to be fixed on the gear by key on the output shaft of 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, on the cylindrical of leading screw, have one to make a good leading screw guiding groove in advance, have one to make good and the corresponding boss of leading screw guiding groove in advance 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 in the end position of leading screw.
Beneficial effect: the present invention 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 demand of different motion parameter rotation with the composite-motion mechanism that advances, overcome existing composite-motion mechanism, be merely able to realize a kind of motion of or a few kinematic parameter, its flexibility degree is lower, once the change of kinematic parameter, then must redesign make, not only use trouble, also have influence on the defective of manufacture cycle simultaneously.
