High-precision high-load four-axis industrial robot wide in adaptability

Abstract

The invention relates to a high-precision high-load four-axis industrial robot wide in adaptability. The high-precision high-load four-axis industrial robot wide in adaptability comprises a rack, a lifting mechanism, a first rotation shaft, a first rotation arm, a second rotation shaft, a second rotation arm and a mechanical pawl, wherein the lifting mechanism is movably arranged on the rack and can ascend and descend on the rack in the vertical direction. The first rotation arm is rotationally connected with the first rotation shaft and can horizontally rotate around the first rotation shaft. The second rotation shaft is connected to the tail end of the first rotation arm. The second rotation arm and the second rotation shaft are rotationally connected, the second rotation arm can horizontally rotate around the second rotation shaft, a harmonic speed reducer is arranged at the tail end of the second rotation arm, and the mechanical pawl is connected to the output end of the harmonic speed reducer so as to grab and rotate a workpiece. According to the high-precision high-load four-axis industrial robot wide in adaptability, more stability is achieved through the mechanical pawl during operation, and the machining precision is greatly improved; meanwhile, the load bearing capability is improved, the service life is prolonged, the overall harmonic speed reducer is small in size and small in weight, the mechanical pawl can stretch into narrow space for work, and the adaptability is wide.

Description

technical field [0001] The invention relates to the field of spare parts assembly and processing, in particular to a high-precision and high-load four-axis industrial robot with wide applicability. Background technique [0002] In the assembly and processing of spare parts, manipulators are often used to grasp and transport spare parts. For example, a four-axis robot is often used in the assembly and processing of USB metal interfaces, and its assembly efficiency is much higher than that of manual work. [0003] The two axes at the end of the existing four-axis robot are mostly spline screw rotating and lifting structures. The spline screw itself is relatively long and bulky, and cannot be extended into areas with small spaces. The load that the spline screw can withstand Smaller, it is easy to bend, deform or even break after being hit. The corresponding software driver needs to be adjusted to make up the difference, and the control is difficult. Contents of the invention...
