Specific embodiment
The present invention will be further described with reference to the accompanying drawing, but protection scope of the present invention is not limited to following institute
It states.
As shown in Figure 1, a kind of be used for aero-engine high-pressure compressor rotor blade listrium grinding attachment, it includes work
Platform 1, clamp body 2, locating piece 3, lateral mass A8 and lateral mass B9, the clamp body 2 are fixed on workbench 1, the lateral mass A8 and side
Block B9 is separately fixed at the two sides of clamp body 2, and the setting of locating piece 3 is in 2 upper surface of clamp body and is located at lateral mass A8 and lateral mass
Between B9,2 bottom of clamp body is equipped with blind hole A14, is equipped with threaded hole A4 in blind hole A14, threaded hole A4 internal screw thread is connected with
Top fastening screw 5,2 side of clamp body are equipped with blind hole B15, threaded hole B6 are equipped in blind hole B15, and threaded hole B6 is arranged in threaded hole A4
Side, threaded hole B6 internal screw thread is connected with lock-screw 7, blind hole C16 is equipped at the top of the locating piece 3, in the clamp body 2
Equipped with threaded hole C12, housing screw 11 is equipped in locating piece 3.
Further, it is higher that 2 upper surface of the clamp body inclination, the lateral mass A8 and lateral mass B9 are arranged at clamp body 2
Side.
Further, tongue-and-groove 10 is equipped in the locating piece 3, lateral mass A8 and lateral mass B9, when rotor blade listrium is ground,
Blade tenon to be ground is mounted in tongue-and-groove 10, guarantees the stability of rotor blade in grinding process.
Further, the tilt angle of 2 upper surface of clamp body is 5 ° 17 ' ± 10 ', and rotor listrium increases face and center
Angled axis institute is 5 ° 17 ', and setting 5 ° 17 ' ± 10 ' for clamp body upper surface tilt angle can guarantee rotor in process
It is horizontal to increase face grinding surface, reduces grinding difficulty.
Further, the workbench 1 is equipped with through-hole 13, and through-hole 13 is located at 5 lower section of Top fastening screw, through-hole 13 and blind hole
