Wireless vacuum flexible fixture based on multi-point support

Abstract

The invention discloses a multi-point support-based wireless vacuum flexible clamp, which comprises a substrate, a plurality of support locating units for clamping a workpiece and a wireless remote controller for wirelessly remotely controlling the support locating units, wherein each support locating unit is provided with a suction cup for clamping the workpiece; a wireless control unit, a wireless pressure sensor and a vacuum pump are arranged in each support locating unit; and starting and stopping of the vacuum pumps are controlled through the wireless remote controller to achieve control on operation of the clamp. According to the clamp, the quantity of the support locating units can be freely configured according to the structure of a thin-wall part; the structures of a bearing plate and the suction cup are changed to avoid the part, such as a coarse surface or a surface with an air leaking hole, which is not suitable for vacuum adsorption; and support locating on a complicated cavity surface of a part is achieved.

Description

technical field [0001] The invention relates to the technical field of part clamping, in particular to a wireless vacuum flexible clamp based on multi-point support. Background technique [0002] Typical aircraft or automobile components are usually designed as multiple thin-walled rib structures due to the need for weight reduction. Multiple cavities of different shapes are formed by ribs, ribs, and webs. The webs of some small cavities The thinnest part of the thickness can be less than 1 mm. For the web with complex structure, variable shape and size, usually it cannot be used as a positioning reference, and it is not suitable to use traditional vacuum fixtures suitable for large plane processing. Therefore, special vacuum fixtures are required. In actual production, there are many types of special fixtures, The large number cannot guarantee the versatility of the fixture, resulting in high cost of fixture tooling. [0003] At present, the flexible positioning tooling f...

For the web with complex structure, variable shape and size, usually it cannot be used as a positioning reference, and it is not suitable to use traditional vacuum fixtures suitable for large plane processing. Therefore, special vacuum fixtures are required. In actual production, there are many types of special fixtures, The large number cannot guarantee the versatility of the fixture, resulting in high cost of fixture tooling

[0003] At present, the flexible positioning tooling for thin-walled curved parts is most representative of the TORRESTOOL flexible fixture system launched by M.Torres in Spain. The TORRESTOOL flexible fixture system is based on the surface multi-point forming technology and adopts a modular array structure. There are a lot of supporting and positioning rod adjustment mechanisms, and each positioning unit needs to be equipped with a control motor and a vacuum pipe, resulting in a large number of wires and intake and exhaust pipes, resulting in complex circuits and expensive construction of the fixture. The control system must simultaneously control dozens of The movement of hundreds of servo motors is difficult to control, and the overall size of the fixture is large, which is not suitable for processing thin-walled parts with small cavities
