An Inverted CNC Lathe with Separated Two Axes

Abstract

The invention discloses an inverted numerically-controlled lathe provided with two separated shafts. The lathe comprises a lathe body, wherein transverse guide rails are fixedly arranged at the upper end of the lathe body and are three horizontal guide rails triangularly arranged in space, a horizontal slide saddle capable of transversely moving along the transverse guide rails is mounted on the transverse guide rails, and a spindle component unit is mounted on the horizontal slide saddle and comprises a spindle and a spindle chuck arranged at the lower end of the spindle; longitudinal guide rails are fixedly arranged on the lathe body below the transverse guide rails and are three vertical guide rails triangularly arranged in space, a vertical slide saddle capable of longitudinally moving along the longitudinal guide rails is mounted on the longitudinal guide rails, and a tool rest is mounted on the vertical slide saddle; a feeding device and a discharging device are arranged on the lathe body on two sides of the longitudinal guide rails respectively. The guide rails adopt three-dimensional layout in the space, the rigidity of the inverted numerically-controlled lathe is increased, the spindle and the tool rest are used as two feed shafts to move, feeding and discharging of workpieces are realized, and the precision and the stability of the numerically-controlled lathe are improved.

Description

Technical field: [0001] The invention relates to the technical field of numerical control machine tools, in particular to a high-rigidity inverted numerical control lathe which is used for processing disc-like revolving parts. Background technique: [0002] With the development of manufacturing equipment technology, the requirements for using lathes to process various discs, shafts, sleeves, covers, wheels and shell-type rotary parts are getting higher and higher. More and more enterprises use CNC lathes for turning. The CNC lathe has functional flexibility. When changing the processing parts, the processing of the lathe can be changed by calling the corresponding CNC processing program. Therefore, when using the CNC lathe for batch processing, the operator actually only plays the role of loading and unloading. Under the processing method of manual loading and unloading, the operators are not only labor-intensive and tense, but also one person can only operate one lathe. I...

The CNC lathe has functional flexibility. When changing the processing parts, the processing of the lathe can be changed by calling the corresponding CNC processing program. Therefore, when using the CNC lathe for batch processing, the operator actually only plays the role of loading and unloading. Under the manual loading and unloading processing method, the operators are not only labor-intensive and tense, but also one person can only operate one lathe

In addition, using this type of CNC lathe to form an automated production line requires additional configuration of a dedicated loading and unloading manipulator.

[0003] At present, conventional vertical inverted CNC lathes adopt the motion distribution method of spindle movement and fixed tool post. The horizontal moving parts of the main shaft and the vertical moving parts are superimposed in series. The errors and deformations between the moving parts affect and accumulate each other, resulting in The accuracy and stability of the machine tool are reduced, and the current lathes are designed with double guide rails, which has an adverse effect on the rigidity and stability of the machine tool
