A CNC lathe

Abstract

The invention discloses a numerically controlled lathe, the structure of which comprises a base, a moving assembly, a screw assembly, a chuck, a lathe body, a dust cover, a lathe tool holder, a guard plate, and a tailstock jacking mechanism, and a lathe is arranged on the base The main body, the lathe body is fixed with a guard plate. Compared with the prior art, the beneficial effect of the present invention is that the screw assembly of the present invention adopts a new structure setting, which is enough to hide the screw, avoid the exposure of the screw, and effectively prevent lathe processing. The generated debris and external dust fall into the thread groove of the screw rod, avoiding the blockage of the thread groove of the screw rod, preventing the scaling of the screw groove, and making the translation of the moving component smooth and unimpeded, so that there is no need to clean and descale the screw rod. The blade mounting seat adopts a new structure setting to achieve multiple fixes, effectively prevent the bolts and blades from loosening, and facilitate the processing of the workpiece by the blade.

Description

technical field [0001] The invention relates to the technical field of numerically controlled lathes, in particular to a numerically controlled lathe. Background technique [0002] CNC lathe is one of the most widely used CNC machine tools at present. It is mainly used for cutting the inner and outer cylindrical surfaces of shaft parts or disk parts, the inner and outer conical surfaces of arbitrary cone angles, the complex rotary inner and outer curved surfaces, cylinders, and conical threads, etc., and can perform grooving, drilling, reaming, and reaming. Holes and borings etc. [0003] The screw is an important component of the CNC lathe. The movement of the tool holder is realized by the cooperation of the screw and the nut pair. However, the existing screw is exposed, and the screw has a thread groove. When the workpiece is processed, cutting chips will be generated, and the cutting chips will also fall into the thread groove, which will hinder the translation of the ...

AI Technical Summary

Problems solved by technology

[0003] The screw is an important component of the CNC lathe. The movement of the tool holder is realized by the cooperation of the screw and the nut pair. However, the existing screw is exposed, and the screw has a thread groove. When the workpiece is processed, cutting chips will be generated, and the cutting chips will also fall into the thread groove, which will hinder the translation of the nut pair. When idle, the dust and impurities in the air will also fall into the thread groove. , will make dust and impurities adhere to the thread groove, forming dirt, which is not conducive to the translation of the nut pair, and it is inconvenient to clean and descale the screw rod;

[0004] In addition, the blades are simply fixed by bolts. Since the blades are subjected to external processing forces and resonance forces during processing, the bolts will loosen, which in turn will cause the blades to loosen, which is not conducive to the processing of the workpiece.
