Industrial table type mechanical arm

Abstract

The invention discloses an industrial table type mechanical arm. The industrial table type mechanical arm is characterized in that a base frame is internally and vertically provided with a first driving motor, the first driving motor drives a big arm rotating disk and a big arm base support to do 360-degree rotational motion through a main transmission connecting disk after the first driving motor is decelerated by a first speed reducer, the big arm base support is provided with a big arm rotating shaft which is horizontally arranged, one end of the big arm rotating shaft is provided with a second driving motor, the second driving motor drives a big arm and a motor installation hanging plate to swing synchronously through the big arm rotating shaft after the second driving motor is decelerated by a second speed reducer, the big arm and the motor installation hanging plate respectively and upwards stretch and are parallel to each other, the motor installation hanging plate is horizontally provided with a third driving motor, the third driving motor drives a connecting rod to swing after the third driving motor is decelerated by a third speed reducer, the upper end of the connecting rod is hinged to the rear end of a small arm, the front end of the small arm is used for installing a mechanical gripper, and the upper end of the big arm is hinged to a position, which is close to the rear end, on the small arm. The industrial table type mechanical arm disclosed by the invention has the advantages that the structure is simple, the processing is convenient, and the flexibility is higher.

Description

technical field [0001] The invention relates to the technical field of industrial robots, in particular to an industrial desktop mechanical arm.

Problems solved by technology

The structure of the current industrial robot is complicated, and the processing is very troublesome. As an important part of the industrial robot, the mechanical arm has very high requirements for flexibility and precision, which makes the structure of the existing manipulator very complicated.

Foreign manipulators are generally expensive and not suitable for widespread promotion and application

[0004] The existing drive motor / reducer of the small arm of the joint robot is mainly located at the upper front end of the arm, and it is prone to low positioning accuracy and vibration or overshoot during the larger movement process, which will reduce the effective speed, thereby Affecting work quality and efficiency, etc.; there are also joint robot forearm transmission motors / reducers located on the centerline of the boom shaft, which requires high manufacturing accuracy and installation accuracy, which will increase product costs. At the same time, parts are prone to appear. The dependence between them is high (that is, coupling), if the manufacturing and installation accuracy is not high, it will cause the interference of related parts
