Description

technical field [0001] The invention belongs to the technical field of manufacturing aero-engine parts, in particular to a universally adjustable centering clamping device. Background technique [0002] In the development process of aero-engines, the manufacturing and processing efficiency of its components often determines the overall development cycle of aero-engines, especially some parts with curved surfaces, and the angle and position of the parts need to be adjusted during processing. The processing difficulty is higher than that of parts with a flat surface. The most typical parts with a curved surface are the inner and outer tiles of the engine, and several studs that need to be processed are distributed on the curved surface. [0003] There are mainly two traditional methods for processing the inner and outer tiles of the engine. The first method is to use an expensive CNC machining center for processing. Although the CNC machining center can meet the processing nee...

[0003] There are mainly two traditional methods for processing the inner and outer tiles of the engine. The first method is to use an expensive CNC machining center for processing. Although the CNC machining center can meet the processing needs of the inner and outer tiles of the engine, its processing cost and use The cost is very high, which leads to the low utilization rate of this method; the second method is to use ordinary lathes for processing, but before processing, it is necessary to design and manufacture corresponding special fixtures for the inner and outer tiles of the engine, and the scope of application of special fixtures Single, at the same time, the utilization rate of the special fixture is very low, and the angle and position of the inner and outer tiles of the engine cannot be adjusted. For the studs, only one can be processed at a time. To process other studs, the tiles must be removed first. , readjust the position of the tiles, and clamp the tiles again. This process is not only time-consuming and laborious, but also easily scratches the tiles during the clamping process, resulting in a high defective rate of the product, and it is difficult for ordinary lathes to pass special fixtures. Improve the processing efficiency of the inner and outer tiles of the engine. This low processing efficiency will directly affect the overall development cycle of the aero-engine
