A Horizontal Multi-Cutter CNC Lathe Based on Precision Machining

Abstract

The invention discloses a horizontal-type multi-cutter-location numerical control lathe based on precise distance machining. The horizontal-type multi-cutter-location numerical control lathe structurally comprises a controlling machine, a numerical control machine, a base and a multi-cutter device, the controlling machine is mounted on the numerical control machine, and the controlling machine andthe numerical control machine are electrically connected; and the numerical control machine and the base are locked, the multi-cutter device is mounted on the controlling machine and constituted by cutter bits, an upper frame structure, middle column structures and an underframe structure, the cutter bits are mounted on the upper frame structure, the middle column structures are connected with the upper frame structure and the underframe structure in a mounted mode, the upper frame structure comprises an upper frame rail, an upper frame threaded strip and an upper frame transverse plate, theupper frame rail is in threaded connection with the upper frame threaded strip, the upper frame rail is welded to the upper frame transverse plate, and the upper frame threaded strip is attached to the upper frame transverse plate. The multi-cutter device moves linearly, long-distance moving, short-distance moving of the upper frame rail and micro-distance moving of the cutter bits are achieved through embedded tracks, the machining routes are omitted, the machining quality is also guaranteed, locally reinforced precise moving is achieved through control rings, and the precision and stabilityof operation of the cutter bits are further improved.

Description

technical field [0001] The invention relates to the field of multi-cutter numerical control lathes, in particular to a horizontal multi-tool numerical control lathe based on precision machining. Background technique [0002] The structure and performance of the tool holder reflect the design and manufacturing level of the CNC lathe. The tool holder is generally used for small CNC lathes. Various tools are arranged and clamped on a movable slide plate, and the workpiece is automatically positioned when changing the tool. [0003] In the prior art, the tool moves through a slide plate. In order to ensure that the tool does not collide with the workpiece when the workpiece is replaced, the tool adopts a U-shaped moving route to avoid the workpiece. The U-shaped route increases the moving distance and reduces the processing efficiency. It is also prone to positioning errors, resulting in reduced processing quality.

Problems solved by technology

[0004] The main purpose of the present invention is to overcome the deficiencies of the prior art and provide a horizontal multi-station CNC lathe based on precision machining, so as to solve the problem that the tool moves through the slide plate, and when the workpiece is replaced, in order to ensure that the tool does not collide with the workpiece. The tool adopts a U-shaped moving route to avoid the workpiece. The U-shaped route increases the moving distance and reduces the processing efficiency. Positioning errors are also prone to occur during the return trip and the positioning of the workpiece, resulting in a decrease in processing quality.
