Four-degree-of-freedom industrial robot for feeding and discharging of numerical control machine tool

Abstract

The invention discloses a four-degree-of-freedom industrial robot for feeding and discharging of a numerical control machine tool. The four-degree-of-freedom industrial robot for feeding and discharging of the numerical control machine tool comprises a fixed base, a large arm, a small arm and a tail end execution component, wherein the large arm comprises a large arm fixed column and a large arm movable column; the small arm comprises a small arm fixed column and a small arm movable column; the large arm fixed column is rotatably connected onto the fixed base; the large arm movable column is connected with the large arm fixed column; the large arm movable column does linear telescopic motion in the large arm fixed column; the small arm fixed column is rotatably connected onto the large arm movable column; the small arm movable column is connected with the small arm fixed column; the small arm movable column does linear telescopic motion in the small arm fixed column; the tail end execution component is fixedly installed at the tail end of the small arm movable column; and a clamping mechanism is installed on the tail end execution component. Compared with an existing feeding and discharging robot, the four-degree-of-freedom industrial robot for feeding and discharging of the numerical control machine tool provided by the invention has obvious differences and advantages, makes up the market vacancy, is more suitable for feeding and discharging work of various numerical control machine tools, has the advantages of being wide in application range, small in occupied space, large in bearing capacity, high in flexibility, low in cost, simple in path planning, easy to control and easy to operate, and has wide market prospects and application values in automatic transformation of the numerical control machine tool industry and the machining industry.

Description

technical field [0001] The invention relates to a robot, in particular to a four-degree-of-freedom industrial robot used for loading and unloading a numerical control machine tool. Background technique [0002] Conventional metal cutting machine tools are divided into horizontal and vertical, and the corresponding machine tool workpiece clamping is also horizontal or vertical. For the loading and unloading robot on the machine tool, only one attitude degree of freedom and three positional degrees of freedom are needed, but the existing loading and unloading robots generally have redundant degrees of freedom. The layout and position dimensions of metal cutting machine tools are designed for manual operation and follow the principles of ergonomics. Therefore, the structure of the machining area of ​​the machine tool is required to be relatively compact, especially the lathe. As the requirements for automatic loading and unloading of machine tools are getting higher and highe...

AI Technical Summary

Problems solved by technology

The truss robot has a large structure size and a long stroke. It needs to be customized according to the machine tool structure size, and its rigidity is poor. It does not meet the needs of automatic loading and unloading of metal cutting machine tools.

Articulated robots are flexible in movement, but in a narrow space, interference collisions are prone to occur, trajectory planning is difficult, operation is inconvenient, and the load is small
