Abstract

The utility model discloses a pneumatic control type radial expansion driver, which is characterized in that a driver body is of a cylindrical structure, four cavities are uniformly divided in the inner circumferential direction, the cavities are mutually connected through air passages, a groove shaped like a conical circular truncated cone is formed at the lower end of the driver, and four exhaust (liquid) grooves are formed in the side surface of the outer wall of the driver at equal angles; the driver can be driven by compressed gas, when the side with smaller deformability expands under the action of compressed air, the axial expansion of the driver is hindered due to the limitation of the axial direction limiting layer, and the driver only expands and deforms in the radial direction. The driver body has extremely high flexibility and strong buffering capacity, and is mainly applied to the field of pneumatic robots.

Description

Pneumatic control type radial expansion driver
Technical Field
The utility model relates to the field of pneumatic robots, in particular to a pneumatic control type radial expansion driver.
Background
In recent years, robots are widely applied in the fields of daily life, industrial production, medical health and the like, wherein soft flexible robots are widely popularized due to the advantages of high flexibility, good flexibility, safety, reliability and the like.
The traditional robot is usually formed by combining rigid parts, has the defects of complex control, poor flexibility, high rigidity, poor safety in a man-machine interaction stage and the like due to the structural characteristics of the robot, and is small in buffering capacity in the motion process and easy to damage a target object. In recent years, with the development of science and technology and new material technology, the rigid driver can not meet the development of robot technology, the appearance of the flexible driver and the rapid development of the robot provide new solution ideas and good prospects, the flexible soft robot is made of flexible materials, the flexible soft robot has the characteristics of the flexible materials, the drivers are deformed by utilizing the air pressure change of compressed air to realize the motion of the robot, the infinite freedom degree is arranged in the space, the motion form and the motion performance of the robot are determined by the structure form of the flexible driver, the robot can be in places with low requirements on driving force but high requirements on flexibility and flexibility.
Disclosure of Invention
The utility model provides a pneumatic control type radial expansion driver of a flexible pipeline robot fixing actuator, which can realize the functions of self-adaptive support, fixation and the like in a pipeline.
The utility model relates to a pneumatic control type radial expansion driver for a robot, which is characterized in that a driver body is of a cylindrical structure, four chambers are uniformly divided in the circumferential direction of the interior of the driver body, the chambers are mutually connected through an air passage, the lower end of the driver is provided with a groove shaped like a conical round table, the driver is conveniently matched and connected with an external mechanism, and four exhaust (liquid) grooves are arranged on the side surface of the outer wall of the driver at equal angles, so that the driver can weaken the motion pressure brought by fluid in a pipeline under the working state.
The pneumatic control type radial expansion driver is thicker in the axial direction and thinner in the radial direction, and the elastic deformation capacity of the pneumatic control type radial expansion driver is weaker than that of the pneumatic control type radial expansion driver in the radial direction due to the constraint of the wall thickness in the axial direction, so that the side wall in the radial direction has better flexibility; the driver can be driven by compressed gas, when the side with smaller deformability expands under the action of compressed air, the axial expansion of the driver is hindered due to the limitation of the axial direction limiting layer, and the driver only expands and deforms in the radial direction.
Drawings
The utility model is described in further detail below with reference to the following figures and detailed description:
FIG. 1 is a general schematic view of a pneumatically controlled radial expansion actuator;
FIG. 2 is an axial cross-sectional view of a pneumatically controlled radial expansion actuator;
FIG. 3 is a radial cross-sectional view of a pneumatically controlled radial expansion actuator;
Detailed Description
The utility model provides a pneumatic control type radial expansion driver, wherein four chambers 4 are uniformly divided in the inner circumferential direction, each chamber is separated by a diaphragm 3, each chamber is connected by an air passage 2, a vent hole 5 is communicated with each air passage, compressed gas enters each chamber from an air pipe through the vent hole 5, an exhaust (liquid) groove 1 is arranged at an equal angle outside the driver, a groove 6 like a conical round table is arranged on one side of the driver, and the driver can be connected with an external mechanism in an embedded connection mode.
