Embodiment Construction

[0020] Examples, see Figure 1 to Figure 3 Shown: a four-axis mechanical arm, including: a J1-axis fixing seat 10, a J2-axis base 20, a J3-axis base 30, a J4-axis telescopic arm 40, and a control system cabinet 50. Specifically:

[0021] The control system cabinet 50 is fixed on the ground, and a control system (not shown in the figure) is arranged inside the system control cabinet 50 . Meanwhile, the first motor 11 is fixed on the control system cabinet 50 .

[0022] The J1-axis fixing base 10 is pivotally connected to the upper part of the control system cabinet 50, the J1-axis fixing base 10 is pivotally connected to the pivot of the control system cabinet 50 and is vertical, and the J1-axis fixing base 10 is connected to the first motor 11 . That is, driven by the first motor 11 , the J1 shaft fixing base 10 can rotate around a vertical axis. The J1-axis fixing seat 10 has a J1-axis arm 12 extending upward. The J1-axis machine arm 12 is provided with a lead screw 22 a...

Abstract

The invention discloses a four-axis mechanical arm. The four-axis mechanical arm comprises a control system cabinet, a J1 axis fixed base, a J2 axis base, a J3 axis base and a J4 axis telescopic arm. Motors for forming motion of the four-axis mechanical arm are all AC servo motors, and therefore the motion speed is high. A harmonic reducer is adopted at the key position, a lead screw and nut mechanism and a pinion and rack mechanism are adopted, and therefore working noise is lowered to a large degree, and motion accuracy is improved; meanwhile, motion parameters of the four-axis mechanical arm are reasonable, and the mechanical arm has good universality.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a four-axis mechanical arm. Background technique [0002] With the popularization and application of industrial automation, robotic arms have been widely used. However, a large number of robotic arms have the defects of slow motion speed, poor motion transmission and positioning accuracy, high noise, and unreasonable motion parameters. Contents of the invention [0003] The purpose of the present invention is to provide a four-axis mechanical arm, which has the characteristics of high motion transmission and positioning accuracy, low noise and reasonable motion parameters. Further, it also has the characteristics of faster action speed. [0004] The technical solution adopted in the present invention is: a four-axis mechanical arm, and the four-axis mechanical arm includes: [0005] ——The control system cabinet, the control system cabinet is fixed on the ground, and the syste...
