Embodiment Construction

[0029] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples are only used to explain the present invention, but not to limit the scope of the present invention.

[0030] like Figure 1 to Figure 3 As shown, a small-load industrial robot includes a base 1, a large arm 2 and a small arm 3; a first servo motor 4 is installed inside the base 1, and the output shaft of the first servo motor 4 passes through the first synchronous pulley. 24 is drivingly connected with the first reducer 15 for driving the swivel base 5 to rotate in the horizontal direction, and a pulley tensioning mechanism 19 for adjusting the timing belt is installed on one side of the first servo motor.

[0031] The boom 2 is installed on the swivel base 5, and a second servo motor 6 is installed in the boom 2. The second servo motor 6 is fixed on the boom 2 through a motor flange. A second synchronous pulley 25 is installed on the ...

Abstract

The invention relates to a small-load industrial robot which comprises a base, a big arm and a small arm. A second servo motor and a third servo motor are mounted in the big arm side by side, bearings are mounted in the other side of the big arm which is provided with a second speed reducer and a third speed reducer, supporting sleeves are mounted on inner rings of the bearings, and cables penetrate through the supporting sleeves to be protected. The second servo motor and the third servo motor are mounted in the big arm side by side, so that the internal structure of the big arm is compact, and the robot is small in size, compact in structure and low in weight. The bearings are mounted in the other side of the big arm which is provided with the second speed reducer and the third speed reducer, so that the requirements for the high precision and the high speed of the robot are met; meanwhile, the bearing capacity of the robot is greatly improved, and stability of the robot is substantially improved. The supporting sleeves are mounted on the inner rings of the bearings, and the cables penetrate through the supporting sleeves to be protected, so that abrasion of the cables is substantially lowered, and the internal structure compactness of the robot is further improved.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a small-load industrial robot. Background technique [0002] Robot-assisted production is often used in industrial manufacturing, production and related technical fields. At present, most of the multi-joint industrial robots on the market belong to six-axis (six-joint) robots. Among them, six-joint low-load robots are favored by most industries. High requirements are required in the design, which requires compact structure, light weight, large load, high speed and high precision. However, the current small-load robots have shortcomings in achieving light weight and high precision at the same time. In the design process of small-load robots, it is urgent to solve the problem that the robot must meet the compactness while requiring precision and speed blocks, and at the same time reduce the weight to a minimum and consider the robot routing mode. SUMMARY OF THE INVENTION [0003...
