Embodiment
Below by embodiment, and with reference to accompanying drawing, the technical solution of the utility model is described in further detail.
As shown in FIG. 1 to 3, a kind of frock for servomotor casing stator press-loading, including mandrel 3, press fitting base
4, the mandrel 3 is multistage multi-diameter shaft, and the mandrel 3 includes the first cylinder 31, the second post being arranged concentrically successively from top to bottom
Body 32, the 3rd cylinder 33, first cylinder 31, the second cylinder 32, the external diameter of the 3rd cylinder 33 successively decrease successively, second post
Body 32 coordinates with the internal wall transitions of stator core 1, and the outer wall circumference uniform distribution of the second cylinder 32 is provided with several grooves 321 and groove
Be provided with magnet 6 in 321, the lower plane of the first cylinder 31 is supported to the inside top surface of stator core 1, the press fitting base 4 including from
The column body 41 and lower prop 42 that top to bottm is arranged concentrically successively, press fitting base 4 home position is provided with to be led to through upper and lower
Hole 43, the through hole 43 and the gap of the 3rd cylinder 33 coordinate, and the top home position of column body 41 is provided with circular groove 411 and top surface
To being laid with several radial screw bores 412 and radial direction spiral shell to the outer side bottom surface of stator core 1, the lower circumferential of column body 41
Pushed up in pit 412 provided with holding screw 5 to the outer wall of the 3rd cylinder 33, the outer marginal circumference of lower prop 42 and be laid with several peaces
Counter sink 421 is filled, convenient press fitting base 4 is fixed on workbench.
The external diameter of column body 41 is less than the internal diameter of casing 2, it is ensured that casing 2 can smoothly press to the upper flat of lower prop 42
Face, complete press fitting work.
The outer wall of not prominent second cylinder 32 of the magnet 6, it is ensured that the second cylinder 32 is matched somebody with somebody with the internal wall transitions of stator core 1
