Four-shaft mechanical arm for grabbing sheet metal parts

Abstract

The invention provides a four-shaft mechanical arm for grabbing sheet metal parts, and belongs to the technical field of four-shaft mechanical arms. The four-shaft mechanical arm for grabbing the sheet metal parts is used for solving the problems that according to a traditional four-freedom-degree articulated robot, a linear movement portion which ascends and descends perpendicularly is arranged at the tail end of a robot body, the mechanism size in the perpendicular direction is large, and the robot is not applicable to operation in a narrow and small space. The four-shaft mechanical arm for grabbing the sheet metal parts is formed by a first shaft unit, a second shaft unit, a third shaft unit, a fourth shaft unit and an electronic control cabinet in a combined mode, wherein the first shaft unit is used for implementing ascent and descent movement of a mechanical arm body, the second shaft unit is used for implementing rotation movement of a large arm, the third shaft unit is used for implementing rotation movement of a small arm, the fourth shaft unit is used for implementing rotation movement of a sucker support, the four shaft units can be used in cooperation, the working range of each shaft is wide, and the four-shaft mechanical arm is quite applicable to operation in the narrow and small space. According to the four-shaft mechanical arm for grabbing the sheet metal parts, the stroke of a first shaft ranges from 0mm to 400mm, the stroke of a second shaft is within the range of + / -180 degrees, the stroke of a third shaft is within the range of + / -135 degrees, the stroke of a fourth shaft is within the range of + / -110 degrees, and repeated positioning accuracy is within the range of + / -0.5mm.

Description

technical field [0001] The invention relates to a four-axis manipulator for grabbing sheet metal parts, belonging to the technical field of four-axis manipulators. Background technique [0002] The traditional four-degree-of-freedom articulated robot (SCARA) sets the linear motion part of the vertical lift at the end of the robot body, and the vertical mechanism is large in size, which is not suitable for narrow space operations. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the above-mentioned prior art, that is, the traditional four-degree-of-freedom articulated robot sets the linear motion part for vertical lifting at the end of the robot body, and the size of the vertical mechanism is relatively large, which is not suitable for working in a narrow space. Furthermore, a four-axis manipulator for grabbing sheet metal parts is provided. [0004] The purpose of the present invention is achieved through the fol...
