Technical field
This programme relates to a kind of NC turret punch machine, and relating in particular to a kind ofly provides power and can realize the main transmission automatic transmission with actuating motor.
Background technique
NC turret punch machine is the key equipment of metallic plate punching processing, as the main drive gear of realizing sheet-metal press working, traditional technology is divided into three kinds, the one, single servo motor directly is connected with main transmission, this pattern velocity ratio is very fast, but be subjected to the restriction that actuating motor can provide moment of torsion, finally this servo turrent punch press can provide the limited in one's ability of stamping-out; The 2nd, between actuating motor and main transmission, connect by a speed reducer, solved the deficiency of direct-connected moment of torsion like this, but the speed of whole main transmission output reduces, manufacturing efficiency reduces; The 3rd, adopt two actuating motors directly to drive main transmission, solve the deficiency of preceding two kinds of situations, but be difficult to guarantee the synchronism of two actuating motors, owing to be two actuating motors, cost of production can increase a lot, the operating cost of equipment also can increase a lot.Though above three kinds of situations are main transmission principal modes of present most of servo turrent punch presss, but the influence of the speed of being subjected to and moment of torsion, greatly reduce the advantage of servo turrent punch press, improved the cost of manufacturing and the operation of equipment, be unfavorable for the development of whole industry.
Summary of the invention
This programme provides a kind of main transmission speed change gear at the deficiencies in the prior art, be implemented in by this device under the situation of an actuating motor, the situation of high-speed and high moment of torsion can be provided according to demand, because what adopt is single servo motor, thereby has reduced manufacture cost and operating cost greatly.
This programme is realized by following technical measures: a kind of NC turret punch machine main variable-speed gearing mechanism, it comprises casing and is set in parallel in splined shaft and output shaft in the casing up and down side by side, it is characterized in that described splined shaft comprises head and afterbody, head diameter is greater than afterbody, center from head end is provided with axis hole along the axis extension, and described axis hole is blind hole; In the head periphery head external splines is set, is provided with the afterbody external splines in the afterbody periphery; Be provided with the blind hole keyway in the blind hole, servo motor shaft stretches in the described blind hole and is connected with the spline axle key;
Head at splined shaft is provided with the 3rd gear, and the 3rd gear has internal spline and cooperates with the head external splines and endwisely slip; Be provided with the 4th gear at the splined shaft afterbody, the 4th gear has internal spline and cooperates with the afterbody external splines and endwisely slip;
Be set with and second gear of the 4th gear engagement and first gear that meshes with the 3rd gear at output shaft;
Be set with connecting sleeve between the 3rd gear and the 4th gear, the inner ring of connection bearing is sleeved on the periphery of connecting sleeve, suit one baffle ring on the outer ring of connection bearing, the outer ring of connection bearing is fixed in the baffle ring by the hole retaining, the inner ring of connection bearing is fixed on the connecting sleeve by axle bumper, connection bearing has been realized connecting sleeve and baffle ring are linked together, and can be in the circumferencial direction relative movement;
At baffle ring connecting sleeve displacement driving mechanism is set.Described connecting sleeve displacement driving mechanism comprises that symmetry is fixedly installed on the guide pillar on baffle ring both sides, and the guide pillar the other end is connected with cylinder.
Two through holes that are provided with in the both sides of described baffle ring symmetry, two guide pillars are installed in respectively in described two through holes and with baffle ring and are fixed together, the other end of guide pillar is provided with tapped hole, by tapped hole respectively be fixed on casing on the cylinder head of 2 cylinders be connected, in the periphery of guide pillar guide pad is set.To-and-fro motion by described cylinder, drive is connected the guide pillar on the cylinder column, the baffle ring that links together with guide pillar, and be connected the connecting sleeve that two gears is connected by bearing with baffle ring, make the axially reciprocal motion on splined shaft of two gears, thereby realized and be fixed on engagement and disengagement between two gears of output shaft, realized the conversion of rotating ratio.
Splined shaft and output shaft all be by bearing fixing in casing and circumferencial direction freely pivot;
Second gear is realized axial limiting with baffle plate, and first gear is fixed on the output shaft by ringfeder, guarantees the precision of gear when assembling by the position of regulating first gear.
The head external splines that arranges on the splined shaft and the length of afterbody external splines reach after the 3rd gear and first gear throw off fully, and the 4th gear and second gear can mesh, and have guaranteed safety.
The beneficial effect of this programme can learn that splined shaft all is to be connected with casing by bearing with output shaft according to the narration to such scheme, has guaranteed precision and the stationarity of reducing gear operation; First gear is connected with output shaft by ringfeder, can guarantee like this to guarantee the operation of mechanism by the position of regulating first gear when assembling; The 3rd gear that links together is connected with splined shaft by spline with the 4th gear, and drive the 3rd gear and the slip of the 4th gear on splined shaft by cylinder, because cylinder has position detecting device and the anterior guiding device that arranges, so guaranteed the 3rd gear and the slip of the 4th gear on splined shaft and the location of position like this, guaranteed the accuracy of gear combination and disengagement.Automatically displacement is to realize by following mode: first gear and the 3rd gear in conjunction with the time, second gear and the 4th gear separate, so present reduction speed ratio is the ratio of first gear and the 3rd gear is 1:1, the speed of output is the speed of motor, and moment of torsion is the moment of torsion of motor; The 3rd gear and first is out of gear under the drive of cylinder, the 4th gear and the second gear combination then, the ratio that reduction speed ratio becomes between second gear and the 4th gear is 1:3, and the speed of output is 1/3 of motor speed, and the moment of torsion that obtains is 3 times of Motor torque.This programme provides a kind of new mode that power is provided for the main transmission of servo digital control turrent punch press, change the Placement of traditional single reduction speed ratio speed reducer and only realized high pulling torque and high-speed by the quantity that changes motor, because speed and moment of torsion are inverse relations, institute at full speed can not get both with high pulling torque, yet adopted the gear of variable reduction speed ratio, realized to obtain high-speed working method at a punch press, the working method of big moment of torsion be can access again, and manufacture cost and the practical cost of equipment reduced.This programme has following feature:
