Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Embodiment 1,
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of integrated transmission case of machine tool, comprising:
Transmission case body 9, planetary gear and torsion clutch 14;
The dynamical system 1 of described planetary power shaft and described lathe is in transmission connection; Described planetary gear comprises sun gear 12, two planetary gears 11 and planet carrier 13, described sun gear 12 is connected with described planetary power shaft fixing coaxial, described two planetary gears 11 are all rotationally connected with on described planet carrier 13, and described planetary output shaft is fixedly connected on the rotating shaft of described planet carrier 13.
Torsion clutch 14 is also provided with between described planetary output shaft and the actuating unit 8 of described lathe; Described torsion clutch 14 comprises power input shaft 22 and power output shaft 27;
The power input shaft 22 of described planetary output shaft and described torsion clutch 14 is in transmission connection, and the power output shaft 27 of described torsion clutch 14 is in transmission connection with the actuating unit 8 of lathe;
Described planetary gear and torsion clutch 14 are all installed in described transmission case body 9.
Described torsion clutch 14 comprises power input shaft 22, power output shaft 27, moment of torsion output slide block 26, spring 24, connects ball 25 and supporting seat 23;
Described power input shaft 22 is arranged with described supporting seat 23, spring 24, moment of torsion output slide block 26 and power output shaft 27 successively from described driven axle 6 side to opposite side; Described supporting seat 23 is fixedly connected on described power input shaft 22, and described moment of torsion exports slide block 26 and power output shaft 27 slip cap is located on described power input shaft 22;
Described moment of torsion exports slide block 26 and described power input shaft 22 is provided with the helical groove mutually mated, and is embedded with described connection ball 25 in described helical groove;
The one side that described moment of torsion output slide block 26 and power output shaft 27 contact with each other is equipped with projection 29;
One end away from described moment of torsion output slide block 26 and the described actuating unit 8 of described power output shaft 27 are in transmission connection.
Contact surface during described machine tool feed between described projection 29 is processed with circular arc chamfering.
Its operation principle is, during retrogressing, start dynamical system 1, sun gear 12 is driven to rotate, sun gear 12 drives planetary gear 11 to rotate around sun gear 12, planetary gear 11 drives planet carrier 13 to rotate, and planet carrier 13 drives torsion clutch 14 to rotate, and torsion clutch 14 drives lathe actuating unit 8 rapid backward.Otherwise when feeding, dynamical system 1 is reversed, planetary gear reverses, and drive torsion clutch 14 to rotate, torsion clutch 14 drives lathe actuating unit 8 feeding.Wherein, the operation principle of torsion clutch 14 is, during inactive state, moment of torsion exports slide block 26 under the effect of spring 24, being in moment of torsion exports on station, now, connects ball 25 and is in bolt indentation near supporting seat 23 side, moment of torsion exports slide block 26 and intersects nested with the projection 29 of power output shaft 27, now moment of torsion export slide block 26 and power output shaft 27 due to projection 29 existence can together with rotate.When lathe starts feeding switch, dynamical system 1 drives power input shaft 22 to rotate by driving driven axle 6, owing to connecting the effect of ball 25 and spring 24, moment of torsion exports slide block 26 and follows rotation, under the effect of projection 29, power output shaft 27 rotates and drives actuating unit 8 feeding, until feeding process terminates, if met with obstruction in feeding process, the resistance that lathe runs into is reverse passes to power output shaft 27 and moment of torsion output slide block 26, when resistance is enough large, overcome the pressure of spring 24, force moment of torsion to export slide block 26, with power output shaft 22, relative motion occurs, under the effect connecting ball 25 and helical groove, moment of torsion exports slide block 26 and moves to supporting seat 23 side, connect ball 5 and be finally in helical groove near power output shaft 7 side, now, the projection 29 that moment of torsion exports slide block 26 and power output shaft 27 departs from mutually, the action of lathe feed-disabling, and dynamical system 1 is with dynamic torque output slide block 26 to be rotated further, when projection 29 turns to nested position, under the effect of spring 24, moment of torsion exports slide block 26 and retracts original position, if now obstacle is removed, then lathe has continued feed motion, if obstacle is not removed, then the projection 29 of moment of torsion output slide block 26 and power output shaft 27 mutually departs under the effect of resistance, go round and begin again, until resistance disappears.
The beneficial effect of employing the technical program is: between the dynamical system and the actuating unit of described lathe of described lathe, be provided with torsion clutch, make lathe when feeding is obstructed, moment of torsion on power transmission shaft increases, and finally make torsion clutch thread off, lathe maintains harmless chucking power, and motor can not burn by stall, now coordinate control circuit to control motor reversal to retreat, this device is mechanical type blocking rotation device, and structure is simple, cost is low, failure rate is low and safe and reliable.Said apparatus and planetary gear speed-reduction geared system are integrated simultaneously and be installed in same transmission case body, make whole transmission mechanism have little, the lightweight and advantages of simple structure and simple of volume.
Embodiment 2,
All the other are identical with embodiment 1, and difference is, described lathe anti-pinch device is also provided with to detect moment of torsion, moment of torsion exports slide block 6 corner or the sensor of moment of torsion output slide block 6 position, and described sensor is electrically connected with described dynamical system.When meeting with obstruction, sensor detects correlated variables, controls dynamical system 1 and reverses, actuating unit 8 is retreated, and is beneficial to remove fault.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, and without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
