Abstract

The invention relates to a four-degree-of-freedom electric joint-type mechanical arm for teaching. The four-degree-of-freedom electric joint-type mechanical arm for teaching comprises a base, a rotary table, an electric big-arm pitching push rod, a big arm, a connection block, an electric telescopic push rod, an electric small-arm pitching push rod and a gripper, wherein the big arm is mounted on the rotary table, the electric big-arm pitching push rod is connected with the rotary table and the big arm via hinges, the connection block is mounted on the big arm, the electric small-arm pitching push rod is connected with the connection block and the electric telescopic push rod via hinges, the gripper is mounted on the electric telescopic push rod, and the rotary table is driven by a rotary motor and a driving mechanism in the base. The four-degree-of-freedom electric joint-type mechanical arm for teaching has the advantages of simple structure, low cost, convenience in mounting and dismounting and capability of meeting requirements on arbitrary positioning of the mechanical arm by means of detecting actual displacement of the electric push rods.

Description

technical field [0001] The invention relates to the technical field of manipulators, in particular to a four-degree-of-freedom articulated teaching electric manipulator. Background technique [0002] With the wide application of manipulator technology, general-purpose teaching manipulators with independent controllers, flexible movements, and suitable for experimental teaching in colleges and universities have developed rapidly. At present, general-purpose teaching electric manipulators use a structure in which the motor is installed at the joint. The driving motors are all installed on each joint of the manipulator, and the motors drive the rotation of each joint of the manipulator to realize various actions of the manipulator; this structure has the following problems: the arm of the manipulator needs to carry the weight of the motor and meet the rigidity requirements. The cross-sectional size needs to be made larger, which will increase the load of the drive motor and the...
