Description

Technical Field

[0001] The present invention belongs to the field of numerically controlled lathes, and in particular relates to an automated production unit for numerically controlled lathes. Background Art

[0002] With the continuous development of science and technology and the continuous maturity of CNC technology, CNC machine tools are becoming increasingly popular. Compared with traditional mechanical processing, CNC machine tools have a higher degree of automation and production efficiency than ordinary machine tools.

[0003] As a type of CNC machine tool, CNC lathes not only have the function of automatically setting the processing route and feed speed according to the processing program, but also have functions such as automatic tool changing, automatic detection, and automatic programming depending on the degree of automation.

[0004] The production efficiency of CNC lathes is closely related to the degree of automation. The higher the degree of automation, the higher the production efficiency, and the higher the processing quality and competitiveness of the enterprise.

[0005] Defects and shortcomings of existing technology:

[0006] Most CNC lathes only address the issue of internal machining automation; loading and unloading, and the transfer of workpieces still require manual labor or auxiliary equipment. For larger workpieces, manual loading and unloading is labor-intensive and inefficient, hindering further improvements in automation and economic benefits. For single CNC lathes, simple manipulators are often used on the market to load and unload workpieces. However, CNC lathes equipped with simple manipulators can only function as independent machining units and are unable to automatically connect the loading and unloading processes of multiple CNC lathes, preventing automated streamlined multi-process machining.

[0007] This plan aims to provide a CNC lathe automation solution that can automatically load and unload materials and change sequences, so that a part can be automatically processed on multiple sets of CNC machining lathes, further improving the degree of machining automation and production efficiency, and improving corporate benefits. Therefore, a CNC lathe automation production unit is proposed. Summary of the Invention

[0008] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract and title of this application to avoid obscuring the purpose of this section, the abstract and the title of the invention, and such simplifications or omissions should not be used to limit the scope of the present invention.

[0009] The existing technology faces the following technical issues: For larger workpieces, manual loading and unloading is labor-intensive and inefficient, hindering further improvements in automation and economic benefits.

A limit plate is also provided on the upper side of the bracket 1, and a detection switch is provided on the limit plate.

[0017] The conveyor belt composed of chain plates can transport two rows of workpieces at the same time. During the workpiece transmission process, the workpieces are transported in an orderly manner through the guide blocks at the end. After the workpieces are transported to the end, they are positioned by the limit plates.

[0018] The detection switch can detect the workpiece in place and notify the six-axis robot to pick up the workpiece or the workpiece conveyor belt to transport the workpiece.
