Description

Technical Field

[0001] The utility model relates to the technical field of processing fixtures, in particular to a fixture for fixing parts with complex curved surfaces. Background Art

[0002] Large casting parts with complex shapes and variable curvatures have multiple reinforcing ribs cast on the bottom. The key issue in processing such parts with complex shapes and variable curvatures is how to fix and clamp the parts. For parts without locating surfaces or locating holes, they are usually fixed and clamped once, and then processed in one go.

[0003] After searching, Chinese patent announcement number: CN217668013U discloses a fixed fixture for fixing parts with complex curvature. The utility model can effectively solve the problems of fixing, clamping and benchmarking of the parts, using the rigidity and plane stability of the base, supplemented by four or six connecting angle plates, one end connected to the base, and one end connected to the reinforcing ribs of the parts. The connecting angle plate needs to be flexibly moved with the base, and finally the base, connecting angle plate and parts are connected into a whole. The flexible connection position of the connecting angle plate on the base makes the fixture applicable to such parts of various sizes. The fixture solves the problems of difficult processing, fixing, clamping and benchmarking of parts, and lays a foundation for the processing and forming of parts.

[0004] Although the above technology can conveniently fix parts through the mutual cooperation of structures such as the base and connecting angle plates, it still has some shortcomings. The above technology cannot replace the fixture. In actual application, different types of parts have different sizes and shapes, and the corresponding fixtures cannot be replaced according to different types of parts, which means that only fixtures suitable for specific sizes can be used. This will result in the fixture being unable to provide sufficient support or clamping force for larger or smaller parts, affecting processing accuracy or safety.
