Abstract

The invention discloses a flexible clamping device and a clamping method, and belongs to the field of tool clamps. The flexible clamping device comprises a tool base body, a hydraulic oil tank and hydraulic pipelines. A plurality of independent cavities are arranged on the tool base body in an array mode, the bottom of each cavity is connected with the hydraulic oil tank through the corresponding hydraulic pipeline, a vertical telescopic supporting column is installed in each cavity, and the bottom of each telescopic supporting column is inserted into the corresponding cavity and is in clearance fit with the corresponding cavity. Each hydraulic pipeline is provided with a hydraulic valve used for achieving opening and closing of each cavity. According to the device and the method, the programmable and high-precision characteristics of numerical control equipment are fully utilized, the device is used in cooperation with various numerical control equipment such as a numerical control machine tool and a mechanical arm, the programmable flexible clamping device with extremely high universality is formed, the device can be used for clamping parts of various structure types, and high-precision posture adjustment of the clamping device is achieved. Compared with a traditional programmable flexible tool, an independent high-precision control system is omitted, and the cost of the flexible tool is greatly reduced.

Description

technical field [0001] The invention relates to a tooling fixture, in particular to a flexible clamping device and a clamping method. Background technique [0002] With the rapid development of the aviation manufacturing field, aircraft models are gradually increasing, and the diversity of demands eventually leads to the diversity of product parts. Parts with different structures and sizes require different clamping schemes, which put forward higher requirements for the versatility of the positioning tooling required for part processing. At present, flexible tooling with programmable features often has an independent high-precision programmable control system. Due to the configuration of an independent programmable control system, the cost of the tooling has been greatly increased, and the maintenance and use of the flexible system have become more complicated. As a result, the application of programmable flexible tooling is greatly restricted. [0003] For example, in the...
