Longitudinal angle rotation mechanism for mechanical arm

Abstract

The invention relates to a longitudinal angle rotation mechanism for a mechanical arm, belonging to the technical field of mechanical arms. The mechanical arm comprises a sucking disc and a sliding rod seat. The longitudinal angle rotation mechanism comprises a first cylinder seat forming a cylinder cavity, a piston, a gear shaft and a revolving seat, wherein the upper end at one side of the cylinder seat is provided with a first adaption hole, while the lower end is provided with a second adaption hole, and a gear shaft hole is formed in the cylinder seat; the piston is arranged in the cylinder cavity, and a rack is formed on the wall body at one side of the piston; the first adaption hole corresponds to one end part of the piston, and the second adaption hole corresponds to the other end part of the piston; the gear shaft is arranged in the gear shaft hole, and a gear is formed on the gear shaft; the revolving seat is fixed with the sucking disc, and a first connecting seat and a second connecting seat are fixed at one side of the revolving seat; one end of the gear shaft is supported on the first connecting seat, while the other end is supported on the second connecting seat; and a first limit bolt and a second limit bolt are arranged on the cylinder seat. The longitudinal angle rotation mechanism has the advantages of simple structure, convenience in manufacturing and quick assembly; the sucking disc is driven to rotate by the gear shaft through the revolving seat; and the rotation angle of the sucking disc can be controlled.

Description

technical field [0001] The invention belongs to the technical field of manipulators, and in particular relates to a longitudinal angle rotation mechanism of a manipulator. Background technique [0002] The concept of a manipulator is well known, and it has the function of imitating human claws and arms to complete certain actions. It is an automatic operating device used to grab, carry objects or operate tools according to a fixed program. It can replace the heavy lifting of people. Labor to realize the mechanization and automation of production. In particular: because it can work in a harmful operating environment to protect personal safety, it is widely used in machinery manufacturing, metallurgy, electronics, light industry and even atomic energy and other fields. [0003] The manipulator is mainly composed of a hand (the industry is accustomed to call it a claw) and a motion mechanism. The hand is a part used to grasp the workpiece (or tool), and has various structural...
