Numerically-controlled lathe

Abstract

The invention relates to a numerically-controlled lathe. The numerically-controlled lathe comprises a lathe body, a lathe body guide rail, a workpiece clamping part and a workpiece processing part, wherein the workpiece processing part comprises a sliding plate frame device and a sliding plate frame driving device is arranged in the lathe body; the sliding plate frame device comprises at least orat least two processing cutter sets; the workpiece clamping part comprises an axial clamping device and a radial clamping feeding device; each processing cutter set on the sliding plate frame device is positioned below a workpiece clamped by the axial clamping device and can vertically move to be in contact with and process the workpiece. According to the numerically-controlled lathe, the space inthe lathe body is effectively utilized, and moreover, the reasonable stressing is realized; the structure is simple; the size, the weight and the manufacturing cost of the lathe are decreased; the lathe is easy to move and maintain. The lathe integrates a plurality of functions and capable of performing cutting, grinding, etc., so that the processing efficiency and the processing accuracy are improved, and the labor cost is decreased; and meanwhile, the automatic feeding and the integral moving of a tail shaft support are performed, so that the structure is simple, and the reliability is high.

Description

technical field [0001] The invention relates to mechanical processing equipment, in particular to a numerically controlled lathe suitable for processing woodworking, metal or other material workpieces. Background technique [0002] A lathe is a machine tool that uses a turning tool to turn a rotating workpiece. It is mainly composed of a bed, guide rails, spindle components, slide plates, tool holders, and tailstocks. [0003] Existing CNC lathes, such as woodworking lathes that are widely used, all adopt a horizontal bed, the slide plate is placed horizontally on the bed guide rail, the tool holder is vertically placed on the slide plate, and the turning tool is fixed on the tool holder and parallel to the horizontal plane. . When working, the sliding plate moves along the guide rail of the bed to realize the axial feeding of the turning tool along the workpiece, and the tool holder moves laterally on the sliding plate to realize the radial feeding of the turning tool alon...

AI Technical Summary

Problems solved by technology

Existing CNC woodworking lathes realize the clamping and releasing of the workpiece by moving the tail shaft back and forth. Therefore, a sliding friction pair needs to be arranged between the tail shaft and the tailstock, and a driving mechanism such as a cylinder or a motor needs to be installed at the end of the tail shaft, resulting in the size of the tailstock and Increased Weight, Reduced Reliability

[0005] At the same time, the existing lathe workpiece needs manual polishing after turning, and manual centering or the use of a more complicated multi-jaw chuck is required when loading and positioning non-standard workpieces, resulting in low work efficiency and poor precision.
