Abstract
The utility model discloses an electric mainshaft digital controlled lathe, comprising an electric mainshaft box, a digital control system, a mainshaft, a transverse and longitudinal ball screw rod, a lathe body guideway, a lathe saddle, two AC servo motors and a whole-closed protective cover, which is characterized in that: a stator and a rotor are arranged in the electric mainshaft box; the rotor is covered on the mainshaft; the transverse ball screw rod is arranged on the middle part of the lathe body guideway; the span of the lathe body guideway is in accordance with the width of the lathe saddle. The utility model directly drives the lathe mainshaft to work through the motor rotor, arranges the transverse ball screw rod on the middle part of the lathe body guideway, widens the lathe surface, increases the span of the lathe body guideway, improves the running stability of the mainshaft and the machining precision of the lathe, increases the rigidity and reduces the vibration and noise, which is more suitable for machining the workpieces with precision and complex shape.
Description
Technical field
The utility model relates to machining equipment, specifically a kind of electric main shaft numerically controlled lathe.
Background technology
The domestic existing numerically controlled lathe transmission device of main motor by belt and gear of all serving as reasons drives lathe spindle work, laterally ball screw is arranged on the lathe front side, the bed ways span is little, and this structure is not only brought noise, vibration and power loss to lathe, also directly influences machine tool accuracy; And make saddle monolateral stressed, and influencing the steady of traverse feed, bed surface is narrow, poor rigidity, vibrating noise is big.
Summary of the invention
The purpose of this utility model is a kind of electric main shaft numerically controlled lathe that designs at the deficiencies in the prior art, it directly drives lathe spindle work by the rotor of motor, horizontal ball screw is arranged on the bed ways middle part, widened bed surface, and strengthened the bed ways span, the running that has improved main shaft steadily and the machining accuracy of lathe, increased rigidity, reduced vibration and noise, be more suitable for, complex-shaped workpiece in processing precise.
The concrete technical scheme that realizes the utility model purpose is: it comprises electric main shaft numerically controlled lathe: electric main spindle box, digital control system, main shaft, horizontal, vertical ball screw, bed ways, saddle, two AC servo motors and totally-enclosed protective cover, characteristics are to be provided with stator, rotor in the electric main spindle box, rotor is sleeved on the main shaft, laterally ball screw is arranged on the bed ways middle part, and the bed ways span is consistent with the saddle width.
The utility model has been simplified mechanical transmission device, the rotor that has designed by motor is sleeved on the main shaft of lathe, directly drive the main shaft of lathe by the rotor of motor, changed former cause master's motor drives main shaft work by the transmission device of belt and gear version, improved the steady and machined into precision of running of main shaft greatly, power loss and vibration have been reduced, laterally ball screw is arranged on the middle part of bed ways, the bed ways span is consistent with the saddle width, make saddle stressed evenly, increased the rigidity of lathe and laterally, feeding longitudinally is steady.
