Problems solved by technology

Since the lead screw is set on the side of the lathe bed, the operation of the large supporting plate is too large due to the traction force of the side screw, which is easy to cause the supporting plate to deviate, causing excessive damage to the side of the bed and increasing the processing speed. Dimensional deviations reduce service life

Abstract

The invention discloses a high-precision numerical control lathe. The high-precision numerical control lathe comprises a lathe body, a lathe head and a base, wherein a groove is formed in the middle of the upper side of the lathe body; the high-precision numerical control lathe also comprises a screw rod end base and a screw rod mother base which are used for fixing a ball screw rod to the lathe body corresponding to the groove; an inversely-concave large support plate is arranged right above the groove; a sliding rail is arranged on each of two sides of the upper surface of the lathe body; sliding plates are arranged on two sliding rails in a spanning manner and are capable of sliding along the two sliding rails in a reciprocating manner; the ball screw rod comprises a nut and screw rods arranged at two ends of the nut. According to the high-precision numerical control lathe, the ball screw rod is arranged in the middle, so that the numerical control lathe is small in oscillation, small in abrasion and high in precision during operation; the processing errors can be greatly reduced; the service life is also prolonged; the safety of the numerical control lathe is ensured; in addition, the screw rod mother base and the screw rod end base are respectively arranged in the lathe body corresponding to the groove, so that the ball screw rod is convenient to maintain, mount and clean; meanwhile, the high-precision numerical control lathe has the symmetrical structure, so that the service life of the numerical control lathe is prolonged.

Description

technical field [0001] The invention relates to the technical field of numerically controlled lathes, in particular to a high-precision numerically controlled lathe. Background technique [0002] CNC lathes and turning centers are high-precision, high-efficiency automated machine tools. Equipped with a multi-station turret or a power turret, the machine tool has a wide range of processing capabilities, and can process complex workpieces such as straight cylinders, oblique cylinders, arcs, and various threads, grooves, and worms. The existing domestic CNC lathe equipment structure is composed of bedside gearbox, bed, side screw, tailstock and drive motor. Since the lead screw is set on the side of the lathe bed, the operation of the large supporting plate is too large due to the traction force of the side screw, which is easy to cause the supporting plate to deviate, causing excessive damage to the side of the bed and increasing the processing speed. Dimensional deviation r...
