Mechanical hand system

Abstract

The invention relates to a mechanical hand system comprising a base and a rotation base installed on the upper end face of the base through a first rotating shaft. The rotation base is connected with a first arm through a second rotating shaft. The first arm is connected with a second arm through a third rotating shaft. The second arm is connected with a connection device through a fourth rotating shaft. A first stepping motor for driving the first rotating shaft to rotate is arranged on the rotation base. A second stepping motor for driving the first arm to move is installed at one end of the second rotating shaft. A third stepping motor for driving the second arm to move is installed at one end of the third rotating shaft. A fourth stepping motor for driving the connection device to move is arranged on the upper end face of the connection device. The first arm and the second arm are arc-shaped bent arms with radian correspondingly. The mechanical hand system does not rely on a servo-driven control module, the control module executes a command mentioned above, the computation of a program is omitted, and the program control cost is saved; and meanwhile, the bent arm design is adopted for the mechanical arms, the rotation radius is large, the volume of the mechanical hand system is effectively reduced, and the mechanical hand system can be more convenient and reasonable during use.

Description

technical field [0001] The invention relates to a manipulator system. Background technique [0002] The industrial manipulator system is a multi-joint manipulator or multi-degree-of-freedom manipulator system for the industrial field, which can grab and carry objects according to a fixed program. The industrial manipulator system can replace the heavy labor of people to realize the mechanization and automation of production, and can operate in harmful environments to protect personal safety, so it is widely used in machinery manufacturing, metallurgy, electronics, light industry and atomic energy. [0003] The existing manipulator system usually completes the rotation of each joint through servo drive, so as to realize the position movement, stay and speed change of the manipulator system in space, etc., but to realize the above actions, it needs to rely on the control module of servo drive, control To execute the above commands by the module, a large number of complex calc...

[0003] The existing manipulator system usually completes the rotation of each joint through servo drive, so as to realize the position movement, stay and speed change of the manipulator system in space, etc., but to realize the above actions, it needs to rely on the control module of servo drive, control To execute the above commands by the module, a large number of complex calculation programs are required, which undoubtedly increases the control cost. In addition, the mechanical arms of the existing manipulator system are designed to be straight, resulting in a small rotation radius of the manipulator and increasing the manipulator system. The volume of the manipulator system causes unreasonable force on the manipulator arm
