Flexible four-DOF (Degree of Freedom) mechanical arm

Abstract

The invention relates to a flexible four-DOF (Degree of Freedom) mechanical arm, relating to mechanical arms. The flexible four-DOF mechanical arm comprises a bracket device and a pneumatic device, wherein the bracket device comprises a horizontal fixed plate, a material storage bracket, vertical brackets and fixed baseboards, wherein both sides of the horizontal fixed plate are respectively fixed with the vertical brackets through positioning pins and bolts; the bottoms of the vertical brackets are fixed with the fixed baseboards through bolts; the material storage bracket is fixed between the two vertical brackets and provided with a material storing device; the pneumatic device comprises a horizontal displacement cylinder, a vertical displacement cylinder, a rotary cylinder and a pneumatic claw, wherein the bottom of the horizontal displacement cylinder is fixed on a connecting piece; the connecting piece is fixed on the horizontal fixed plate through bolts; the bottom of the vertical displacement cylinder is fixed on one end of the horizontal displacement cylinder; the tail end of the vertical displacement cylinder is fixed with the rotary cylinder; and the rotary cylinder is fixed with the pneumatic claw through a flange. In the invention, the blocky parts or the parts with inner holes can be conveniently grabbed and arranged on specified positions, and the invention has the advantages of high grabbing accuracy and reliability and small size.

Description

technical field [0001] The invention relates to a manipulator, in particular to a flexible four-degree-of-freedom manipulator. Background technique [0002] With the development of technology, more and more manipulators are used in various fields, especially in automatic production lines. However, most of the manipulators used in automatic production lines are relatively large, which is not suitable for the production of small parts, because tiny parts are not easy to clamp If it is not supported, the manufacturing requirements for the manipulator will be very strict, not only to achieve high-precision grasping but also to improve work reliability. For example, in the production of civil power switches, due to the small size of each part, it is not easy to grasp, and currently it is still installed manually, which is very inconvenient. Contents of the invention [0003] The object of the present invention is to provide a flexible four-degree-of-freedom manipulator to solv...
