Clamping components and clamping devices

Abstract

The invention relates to a clamping assembly and a clamping device. The clamping assembly includes a driving part and a clamping part. The driving part is provided with a driving chamber and a fluid inlet and outlet. The driving chamber communicates with the outside through the fluid inlet and outlet. The clamping part is close to the driving part. One side is provided with a driving diaphragm, the clamping part includes at least two jaws, at least one jaw is connected to the driving diaphragm, the driving diaphragm can be deformed with the filling and discharging of the fluid in the driving chamber, and is driven to connect to the driving diaphragm The jaws move so that at least two jaws open and close. The clamping assembly provided by the present invention can realize soft contact between the clamping jaws and the clamped object, and has high applicability and versatility; the internal structure of the clamping assembly is simple, and the manufacturing cost and use cost are relatively low; Moreover, the driving method is simple, suitable for working in a narrow space, and occupies a small area, which is conducive to the development of miniaturization of products.

Description

technical field [0001] The invention relates to the field of flexible clamping, in particular to a clamping assembly and a clamping device. Background technique [0002] The flexible clamping device is a new type of execution device that is different from the traditional rigid clamping device. With the maturity of robot technology, robot applications have begun to develop from a single repetitive operation method to flexibility and high compatibility. The end of the robot is executed. The mechanism is also developing in the direction of high flexibility, high adaptability and high reliability. Comparatively speaking, when the clamping device made of flexible material is used as a robot actuator, it has better adaptability to the working environment and the working object due to its own material and structural characteristics. In the process of collision, you can better protect yourself and your collaborators. [0003] At present, flexible robot actuators are mainly divided...

AI Technical Summary

Problems solved by technology

[0003] At present, flexible robot actuators are mainly divided into three types: 1. Driven by a rigid structure and equipped with a soft material buffer at the end, this type of flexible clamping device has limited adaptability, and can only be easily adapted through a buffered soft material, lacking universal 2. Rigid structure drives and feeds back the real-time clamping force through electrical signals. This type of flexible clamping device realizes closed-loop clamping control by reading the force sensor in real time, with high precision and controllability, but often the structure and control are inconsistent. It is relatively complicated, and the cost of production and maintenance is high; 3. Utilizing the deformation characteristics of flexible materials, one or more groups of airbags are used to drive the bending of the jaws, which has high adaptability and versatility, but this type of flexible clamping device Requires a large working space and is difficult to work in a small space
