Abstract

The invention relates to a clamping platform for integral turbine disc bucket groove forming and grinding machining and an operation process of the clamping platform. The clamping platform is characterized in that two ends of a rotating middle shaft of the platform are connected with a flange and a two-way positioning mechanism correspondingly, a turbine disc is clamped through the flange, the two-way positioning mechanism can realize clockwise or anticlockwise positioning rotation of the rotating middle shaft according to a fixed angle, an upper supporting rod is connected with a middle shaftshell, bearings are arranged at the two ends of the rotating middle shaft and installed in a shell, the upper supporting rod is provided with a bearing and a positioning pin and connected with a mainsupporting frame, so that two-degree-of-freedom positioning rotation of a turbine disc is achieved, and then under one-time clamping and positioning of the turbine disc, forming and grinding machining of the integral turbine disc bucket groove is achieved.

Description

technical field [0001] The invention belongs to the technical field of high-efficiency precision machining, and in particular relates to a clamping platform used for forming and grinding an integral turbine disk tenon and groove and an operation process thereof. [0002] technical background [0003] Form grinding is to prepare and trim the grinding wheel into a reverse surface that completely matches the workpiece surface, and then use the grinding wheel to grind the workpiece to obtain the desired shape; or when grinding the workpiece, make the workpiece It is clamped on a special fixture according to certain conditions. During the processing, the position is fixed or continuously changed for grinding to obtain the desired shape. [0004] Although the use of finger-shaped grinding wheels does not require re-clamping or multiple positioning of the two profiles, because the finger-shaped grinding wheel itself contains a small number of abrasive grains, the tool wears seriousl...
