The technical scheme of the utility model is that:
a position feedback mechanism commissioning device comprising: an open end wrench, a round end wrench, a straight end wrench, a hook-shaped wrench and a rivet; the tail parts of the open end wrench, the round head wrench, the straight wrench and the hook type wrench are fixedly connected through rivets.
As above the tail parts of the open end wrench, the round head wrench, the straight wrench and the hook type wrench are all provided with the mounting through holes with the same size for fixedly mounting the rivet, and the tail parts of the open end wrench, the round head wrench, the straight wrench and the hook type wrench can be fixed on the rivet to be rotationally adjusted.
The end of the open-end wrench is provided with a groove, and the size of the groove is matched with that of the stroke mechanism nut.
As mentioned above the round head spanner end is the cylindrical structure, the cylindrical size and the position feedback mechanism on the stroke fan-shaped pressure plate in the cylinder groove matching.
The end part of the straight wrench is of a straight-line-shaped cylindrical structure, and the size of the end part of the straight wrench is matched with the size of an adjusting knob on a position feedback module on the position feedback mechanism.
As mentioned above, the end of the hook-type wrench is integrally of a semicircular structure, the upper end of the end is also provided with a rectangular groove, and the size of the rectangular groove is matched with the size of a stroke pressing sheet adjusting hole on the position feedback mechanism.
The utility model discloses following beneficial effect has:
the utility model discloses a position feedback mechanism debugging device collects multiple functions such as stroke mechanism debugging, position aperture adjustment debugging of multiple structure, and stable in structure is reliable, and application method is simple, does not need to change the debug tool many times, and the problem of easy landing and loss of solution debug tool in the field debugging in-process that can be convenient and reliable to need not to change the debug tool many times and just can accomplish the technical problem of final debugging at the debugging in-process.
