Description
Technical field
The present invention relates to a kind of mechanical transmission mechanism, particularly a kind of any rotation and the composite-motion mechanism that advances belong 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 any rotation and the composite-motion mechanism that advances are provided, this any rotation and the composite-motion mechanism that advances, 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.
Working principle of the present invention is: the forward drive actuating motor drives leading screw by the key gear rack and does to advance and the motion that retreats, rotation drives actuating motor by being with synchronously, big synchronous pulley is that screw mandrel rotatablely moves, because the forward drive actuating motor drives servo motion with rotation and can control arbitrarily by program, so the rotation of leading screw can realize any control with the kinematic parameter that advances.
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.
