Problems solved by technology

[0008] However, in the prior art, there is insufficient grasping space, the stroke of the soft hand is short, and it cannot adapt to the grasping of large-volume items. In addition, the pneumatic clamping hand needs to be deformed during the clamping process, and the At present, it is deformed in the form of rushing into high-pressure gas, and high air pressure is required to achieve deformation and clamping

Abstract

The invention relates to a variable-stroke soft pneumatic gripping device and a working method thereof. The variable-stroke soft pneumatic gripping device comprises an installation base plate, whereina center of a bottom end of the installation base plate is fixedly connected with a drive device, a center of a top end of the installation base plate is rotationally connected with a shaft flange, the shaft flange is connected and driven by a drive device, a top end of the shaft flange is rotationally connected with a plurality of connecting rods along an edge of the shaft flange, one ends of the connecting rods away from the shaft flange are rotationally connected with moving bases, top ends of the moving bases are fixedly connected with gas claws, the plurality of gas claws can be driven to move by the shaft flange so as to grip an object, a motion track is larger, and clamping adaptability is higher; by forming tooth grooves and air filling grooves on the gas claws, the bending gripping of the gas claws can be realized in a smaller power, the power requirement is lower, the use is more convenient, and the gripping effect is better.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a variable-stroke soft pneumatic clamping device and a working method thereof. Background technique [0002] With the development of robot technology and the continuous expansion of intelligent manufacturing production mode, multi-variety and small-batch production mode is becoming more and more common. Rigid manipulators have been difficult to adapt to the needs of grasping workpieces. The application of traditional rigid manipulators on manufacturing production lines is an important reason for the liberation of labor. Most of them are made of rigid materials that limit elastic deformation. Relying on precise mathematical models, they have high accuracy, sufficient power, high power, and high performance. Mature features have been widely accumulated and applied in many fields such as industry, medical treatment and special environment, and its application tends to...
