Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of machine tool mechanical formula limit transmission device is provided with torsion clutch between the equipment actuating device 8 of the power system 1 of described machine tool and described machine tool.
Described torsion clutch comprises power input shaft 2, pto 7, moment of torsion output slide block 6, spring 4, connects ball 5 and supporting base 3;
Described power input shaft 2 one ends and described power system 1 are in transmission connection;
Described power input shaft 2 is arranged with described supporting base 3, spring 4, moment of torsion output slide block 6 and pto 7 successively from described power system 1 one side direction opposite sides; Described supporting base 3 is fixedly connected on the described power input shaft 2, and described moment of torsion output slide block 6 and pto 7 flip sleeves are located on the described power input shaft 2;
Described moment of torsion output slide block 6 and described power input shaft 2 are provided with the helical groove of mutual coupling, are embedded with described connection ball 5 in the described helical groove;
The one side that described moment of torsion output slide block 6 and pto 7 are in contact with one another is equipped with projection 9;
An end and the described equipment actuating device 8 away from described moment of torsion output slide block 6 of described pto 7 are in transmission connection.
During state of rest, moment of torsion output slide block 6 is under the effect of spring 4, be on the moment of torsion output station, at this moment, connect steel ball 5 and be in bolt indentation near supporting base 3 one sides, the projection 9 of moment of torsion output slide block 6 and pto 7 intersects nested, and this moment, moment of torsion output slide block 6 and pto 7 were owing to the existence of projection 9 can be rotated together.
Working principle is, when power system starts, power system 1 drives power input shaft 2 and rotates, owing to connect the effect of steel ball 5 and spring 4, moment of torsion output slide block 6 is followed rotation, under the effect of projection 9, pto 7 rotates and 8 runnings of the equipment of drive actuating device, if overload or stuck situation take place in running, reverse pto 7 and the moment of torsion output slide block 6 of passing to of this resistive torque, when resistance is enough big, overcome the pressure of spring 4, force moment of torsion output slide block 6 and pto 2 that relative movement takes place, under the effect that connects steel ball 5 and helical groove, moment of torsion output slide block 6 is to supporting base 3 one side shiftings, connect steel ball 5 and finally be in helical groove near pto 7 one sides, at this moment, the projection 9 of moment of torsion output slide block 6 and pto 7 breaks away from mutually, the action of equipment actuating device 8 phase downs, and power system 1 drive moment of torsion output slide block 6 is rotated further, when projection 9 turns to nested position, under the effect of spring 4, moment of torsion output slide block 6 is retracted original position, if trouble shooting this moment, then equipment actuating device 8 remains in operation, if fault is not removed, then the projection 9 of moment of torsion output slide block 6 and pto 7 breaks away under the effect of resistance mutually, goes round and begins again, and disappears up to resistance.
Carry out pinpoint the time at needs, earlier with accurately location and the locking of accurate positioning baffle, starting device then, power system 1 drives power input shaft 2 and rotates, owing to connect the effect of steel ball 5 and spring 4, moment of torsion output slide block 6 is followed rotation, under the effect of projection 9, pto 7 rotates and 8 runnings of the equipment of drive actuating device, when actuating device 8 touches accurate positioning baffle, promptly arrive the exact position of setting, at this moment, from reverse pto 7 and the moment of torsion output slide block 6 of passing to of the resistance of accurate positioning baffle, finally overcome the pressure of spring 4, force moment of torsion output slide block 6 and pto 2 that relative movement takes place, under the effect that connects steel ball 5 and helical groove, moment of torsion output slide block 6 is to supporting base 3 one side shiftings, connect steel ball 5 and finally be in helical groove near pto 7 one sides, at this moment, the projection 9 of moment of torsion output slide block 6 and pto 7 breaks away from mutually, the action of equipment actuating device 8 phase downs, and power system 1 drive moment of torsion output slide block 6 is rotated further, when projection 9 turns to nested position, under the effect of spring 4, moment of torsion output slide block 6 is retracted original position, the projection 9 of moment of torsion output slide block 6 and pto 7 breaks away under the effect of resistance mutually, go round and begin again, this moment can be by detecting moment of torsion, the sensor of moment of torsion output slide block 6 corners or moment of torsion output slide block 6 positions is controlled power system 1 counter-rotating, these sensors drive actuating device 8 and retreat, finish once accurately positioning operation, owing to can be installed on device inside, be not subjected to the influence of external environment condition, so the reliability height, and the validity of location and sensor are irrelevant, so Location accuracy is not subjected to the influence of sensor accuracy.
