A modular flexible fixture

Abstract

The invention discloses a modularized flexible fixture, which belongs to the field of precision assembly. The flexible fixture includes a detection module, a force balance module, a clamping module and an adsorption module. A modular flexible fixture can realize the flexible clamping of various micro-small parts through the combination of different modules. The detection module includes a force sensor, an adjustment screw and a spring, which can detect the magnitude of the force during part clamping and assembly in real time. The force balance module includes a fixture base, a miniature linear slide, a slide connecting plate, a limit block, a fixed plate, a balance shaft, a spring adjustment nut, a connecting plate, a spring, and a linear cylinder, so as to realize the self-weight balance of the fixture and ensure the clamping and assembly of parts Accurate detection of forces in the process. The clamping module includes parallel cylinders and grippers, enabling clamping of different types of parts. The adsorption module includes a guide seat, a guide shaft, a spring, an air circuit joint, a suction cup adapter plate and a suction cup. Replacement of different adsorption modules can realize the adsorption of different micro-sized parts.

Description

technical field [0001] The invention belongs to the technical field of precision assembly, and relates to a modular flexible clamp. Background technique [0002] With the continuous development of precision micro-miniature assembly technology, traditional manual assembly and human-machine collaborative semi-automatic assembly technology are increasingly unable to meet the needs of efficient production efficiency and product consistency. Fully automated assembly technology can not only greatly improve product production efficiency, but also effectively ensure product consistency and reliability. In order to realize the fully automated assembly of micro and small brittle and fragile parts, the traditional clamping technology cannot achieve effective non-destructive clamping. It is necessary to adopt flexible clamping technology and design suitable flexible fixtures. [0003] In addition, the field of precision assembly is often multi-variety and variable batch production.
