Abstract
The utility model provides a mounting structure of a main drive double servo motor in a punching machine, comprising a pair of servo motors, a crankshaft which can enable a punching head to make vertical movement, keys, a bellevill spring, a shaft shoulder screw and a stander. Hollow shafts of the servo motors are respectively mounted at the left end and the right end of the crankshaft; flanges of the servo motors are fixedly connected with the stander of a punch through the shaft shoulder screw, the bellevill spring and the keys; the keys are mounted in key grooves of the mounting surface of the stander and the flange surfaces of the servo motors; and the shaft shoulder screw is connected with a threaded hole of the mounting surface of the stander by sequentially penetrating through mounting holes of the flange surfaces of the servo motors and the bellevill spring. The mounting structure of the main drive double servo motor in the punching machine can enable the machining to be simple, economical and fast, and can protect the servo motors, thereby prolonging the service lives of the servo motors.
Description
Technical field
The utility model relates to a kind of structure of press, is specifically related to the mounting structure of the two main transmission actuating motors in a kind of press.
Background technology
Two main transmission actuating motors in the press is to use AC servo motor, as the main transmission power source, directly be connected with crankshaft two end, fix with lathe in some way again, directly driving bent axle rotates, thereby drivening rod mechanism moves up and down, and realizes energy-conservation, the quick and accurate punching press to sheet material.Because the hollow shaft sleeve of bent axle and two motors is connected as a single entity, the hollow shaft of bent axle and motor has higher axiality requirement; And the installed surface of the flange face of motor and lathe is connected and fixed, motor adds man-hour, the flange face of motor and the center line of hollow shaft sleeve have the perpendicularity requirement, but there is mismachining tolerance, the installed surface of lathe adds man-hour, with bent axle supported hole center line the perpendicularity requirement is arranged, there is mismachining tolerance equally, and the installed surface of motor is distributed in the both sides of fuselage on the lathe, and two motors are mounted on the same bent axle, guarantee that two installed surfaces are vertical fully with crankshaft axis, the fixed form of motor and lathe is quite important, it is improper to install, and not only influences the machining accuracy of lathe, and main is that shortened the service life of motor.
The mounting means of habitual motor is that motor flange face and frame installed surface do not have the gap and be screwed in the press, the error of perpendicularity of installed surface and motor shaft center line directly acts on motor, and must being the motor inner bearing, this error of perpendicularity can bear, if exceed the scope that motor bearings can bear, will have a strong impact on the use of motor, shorten its life-span.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, the mounting structure of the two main transmission actuating motors in a kind of press is provided, and this structure has solved in the existing mounting means problems such as process equipment precision height, processing technology complexity and motor inner bearing be fragile.
The technical solution of the utility model is: the mounting structure of the two main transmission actuating motors in a kind of press, comprise a pair of servomotor, the bent axle that drift is moved up and down, key, the butterfly spring, shaft shoulder screw and frame, the hollow shaft of described a pair of servomotor is installed in the two ends, the left and right sides of bent axle respectively, the flange of described servomotor is by described shaft shoulder screw, butterfly spring and key are fixedlyed connected with the frame of lathe, described key is installed in the keyway of frame installed surface and servomotor flange face, its effect is the location of motor circumferencial direction and transmits the moment of torsion that motor produces, described shaft shoulder screw passes the installing hole of servomotor flange face successively, the butterfly spring is connected with the screwed hole of frame installed surface, the effect of shaft shoulder screw is axial the fixing of servomotor and frame, the effect of dish spring mainly be eliminate the motor installed surface may be with the crankshaft axis error of perpendicularity to the unfavorable factor of motor generation, suitable gap between control motor flange face and frame installed surface provides the Free up Memory of a flexibility for this error.
The beneficial effects of the utility model are:
1, can make machining become simply, economical and quick.The mounting means of motor requires the equipment precision height of processing installed surface in the existing press, and also relative complex of processing technology, adopt the mounting means of the utility model shaft shoulder screw, butterfly spring and key, only need to adopt common process equipment, guarantee that general machining accuracy gets final product.
2, servomotor is had protective effect, prolonged the service life of servomotor.Be decided by the service life of the bearing of servomotor inside the service life of servomotor generally speaking.And the coaxiality error of the service life of bearing and armature spindle has and directly gets in touch; installed surface is the axial line out of plumb of axle therewith; cause motor inner bearing axle disalignment therewith; thereby cause the very fast damage of motor inner bearing not work; adopt mounting means of the present utility model; can eliminate above-mentioned undesirable element, motor is had substantial protective effect.
