DEVICE FOR THE ACCURACY complex profiles polishing GTE blades

摘要

The proposed utility model relates to devices for measuring the geometric parameters of the compressor and turbine blades. Summary of the utility model is that the device to control the geometric parameters of the blades of the pen comprises a horizontal base, two vertical bracket arranged based on different sides of a controlled blade and rigidly connected crossbar, four carriage connected to the U-shaped strap, on the two carriages on each bracket having a possibility of vertical displacement, provided with a linear encoder, the measuring system composed of line sensors with measuring spherical tipped controlled pneumatic actuator, a movable carriage disposed on the base, movable between brackets in the longitudinal direction, provided with a drive, controllable by the PC and the second linear encoder, tooling for installing the blade having a drive controlled by the PC, tooling for fastening blade rigidly fixed to the quick-pallet, which is mounted in a cartridge mounted on a movable carriage. The U-shaped bracket fixed marking device, which is a pair of axially spaced lasers. The technical result - improved accuracy, reducing the complexity of the polishing process. 3 ZP f-ly 1 Fig.
