Four-degree-of-freedom pneumatic manipulator

Abstract

The invention discloses a four-degree-of-freedom pneumatic manipulator which comprises a base. A rotary cylinder block is mounted at the upper end of the base. A telescopic cylinder block is mounted at the upper end of the rotary cylinder block and connected with a connecting barrel. The upper portion of the connecting barrel is connected with a long connecting block connected with an arm telescopic air cylinder. The arm telescopic air cylinder is connected with a wrist rotary air cylinder through a small cylindrical connecting block. The wrist rotary air cylinder is connected with a gripper through a big cylindrical connecting block. The gripper is provided with V-shaped fingers so as to grab a workpiece in a specific shape. Gaskets are mounted on the V-shaped fingers, so that the workpiece is not prone to falling off when the workpiece is grabbed. By adoption of a pneumatic transmission system, the four-degree-of-freedom pneumatic manipulator has the characteristics that a runner pipe is not prone to clogging, the environment is not polluted, temperature influences are small, the resistance is small, response is quick, the retention ability and reliability are high, the environment adaptability is good, the structure is simple, the cost is low, and maintenance is simple.

Description

technical field [0001] The invention relates to the field of industrial robots, in particular to a four-degree-of-freedom pneumatic manipulator. Background technique [0002] The manipulator is the earliest industrial robot and the first modern robot. It can replace the heavy labor of people to realize the mechanization and automation of production. It can operate in harmful environments to protect personal safety. Manipulators can be widely used in production fields, especially In harsh environments such as high temperature, high pressure, dust, explosive, toxic gas and radioactivity, it is more meaningful to replace people in normal work. Therefore, it is widely used in machining, stamping, casting, forging, welding, heat treatment, electroplating , painting, assembly and light industry, transportation and other aspects have been more and more widely used. The application of manipulators in production can improve the automation level and labor productivity of production; ...

Problems solved by technology

[0003] For workpieces of a certain shape produced in small batches, it is generally necessary to design a general-purpose manipulator at this time. The general-purpose manipulator has strong versatility and can meet workpieces of different sizes. The design is complicated and the cost is high. Therefore, it is necessary to design a general-purpose manipulator device to solve the problems of unstable and easy-to-slip gripping of the manipulator, and the problem of complex structural design and high cost.
