Problems solved by technology
[0004] Aiming at the deficiencies of the above-mentioned prior art, the present invention provides an industrial robot to solve the problem that in the prior art, the rotation eccentric distance of the elbow is large, the work space is large, the stiffness of the elbow is low, the weight is large, and the precision is not high enough. The technical problems of not being flexible enough to move and not smooth in shape can greatly reduce the rotational eccentric distance of the elbow and improve stiffness, precision and flexibility

Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0025] an industrial robot such as Figure 1 to Figure 8 As shown, it includes an elbow 1 and a forearm 2, the forearm 2 includes a forearm main body 24, and the elbow 1 includes an elbow main body 11; the rear end of the forearm main body 24 is docked with the front end of the elbow main body 11; Forearm main body 24 rear end is equipped with forearm motor 21, and the output shaft of described forearm motor 21 deviates from the axis line of forearm main body 24, and forearm motor 21 carries out power transmission through forearm synchronous pulley; The synchronous pulley includes a driving wheel 22, a driven wheel 23 and a synchronous belt. The driving wheel 22 is sleeved on the output shaft of the arm motor 21, and the axis line of the driven wheel 23 coincides with the axis line of the arm body 24; the elbow The main body 11 is p...

The invention discloses an industrial robot. The industrial robot comprises an elbow and a forearm. The back end of a forearm main body is in butt joint with the front end of an elbow main body. A forearm motor is installed at the back end of the forearm main body. An output shaft of the forearm motor is deviated from the axis line of the forearm main body. The forearm motor conducts power transmission through a forearm synchronous belt wheel. The elbow main body is internally provided with a butt joint baffle. The butt joint baffle divides the elbow main body into a front chamber and a back chamber. A harmonic reducer is installed in the front chamber and comprises a wave generator, a flexible wheel and a rigid wheel. The axis line of the wave generator overlaps with that of the elbow main body. The wave generator and a driven wheel of the forearm synchronous belt wheel are connected and are on the same axis, and thus power is input into the harmonic reducer and output to the forearm main body through the rigid wheel. According to the industrial robot, the rotating eccentric distance of the elbow is shrunk meanwhile the size of the elbow is reduced, the working occupation space is reduced, the weight of the elbow is reduced, the stiffness, the precision and the flexibility of the elbow are improved, and the appearance beautiful degree is improved.
Description
technical field [0001] The invention relates to an industrial robot. Background technique [0002] With the development of the machinery industry, more and more fields use industrial robots to realize automated production in order to improve production efficiency and product quality. Industrial robots generally mainly include arms, shoulders, forearms, elbows and wrists. The elbow in the prior art is a split structure, so that the elbow can be disassembled to facilitate the installation of the forearm motor on the rear end part of the elbow (forward installation), and the installation of the forearm motor in the elbow requires the elbow The volume size is larger, which will make the rotation eccentric distance of the elbow larger. The rotation eccentric distance of the elbow refers to the distance from the center of the elbow reducer (installed in the boom) to the axis of the forearm reducer. The larger the rotation eccentricity distance, the larger the space occupied by t...
