Abstract

The invention discloses a synchronous telescopic adaptive multi-point support fixture for the processing of annular thin-wall workpieces, and belongs to the technical field of machining. The synchronous telescopic adaptive multi-point support fixture comprises a base, lower pressing plate assemblies, a lower bearing fixing assembly, upright columns, a height regulating plate, connecting rod and sliding block mechanisms, a lead screw nut mechanism, floating auxiliary supporting assemblies, an upper bearing fixing assembly and an upper press cover, wherein a single degree of freedom height regulating structure is formed by the upright columns and the height regulating plate, and in combination with the lead screw nut mechanism and the connecting rod and sliding block mechanisms, the synchronous telescopic adaptive multi-point support fixture forms a cylindrical coordinate type supporting system taking radial positions and axial positions as control variables in terms of spatial orientation and motion mode. The synchronous telescopic adaptive multi-point support fixture has the advantages that synchronous telescoping with multi-point radial support can be realized, and uniform supportcan be provided for the workpieces; the support regulating range is large, so that supporting demands of the workpieces with different diameters and heights can be met.

Description

technical field [0001] The invention belongs to the technical field of mechanical design, and in particular relates to a synchronous telescopic self-adaptive multi-point support fixture used for processing annular thin-walled parts. Background technique [0002] With the continuous expansion of application fields and continuous improvement of performance indicators, aerospace, energy power, national defense and military industries have higher requirements for the instruments and equipment used, and various structural parts are developing towards lightweight. Among them, annular thin-walled parts, as a typical structural part, are widely used because of their light weight and compact structure, such as aero-engine casings and rotating hubs. This kind of annular thin-walled part has the characteristics of complex shape, large size and thin wall thickness in structural design, which makes it prone to instability or vibration due to insufficient rigidity during processing, and i...
