Described positioning sleeve is annulus rod structure, and the lower surface of described positioning sleeve contacts with the upper surface of described first boss, the madial wall of described positioning sleeve and the lateral wall matched in clearance of described second boss.
The external diameter of described cylindrically coiled spring is less than the external diameter of described second boss, and the lower surface of described cylindrically coiled spring contacts with the upper surface of described second boss, and the upper surface of described cylindrically coiled spring contacts with the lower surface of described upper dish.
Described upper dish is annulus rod structure, and described upper dish comprises the cotter way hole arranged in the horizontal direction, and described cotter way hole diametrically runs through described upper dish two lateral wall, and the lower surface of described upper dish contacts with the upper surface of described cylindrically coiled spring.
Described straight pin runs through in the horizontal direction and is arranged in described cotter way hole and described pin-and-hole, and described straight pin can move up and down in described cotter way hole, and described upper dish can be moved up and down within the spacing scope in described straight pin and described cotter way hole.
Described cross axle bearing shell is arranged at described axis body top, and described cross axle bearing shell lower surface contacts with described axis body upper surface, the lateral wall of described cross axle bearing shell and described upper dish madial wall matched in clearance.
The height of described second boss and the minimum of contraction height sum of described cylindrically coiled spring are less than the height of described positioning sleeve.
Compared with prior art, the beneficial effect that the utility model has is:
A kind of frock being applied to shaft universal-joint component and press-fiting of the utility model, 1) manual assembly mode traditional for shaft universal-joint bearing shell can be changed into employing Normal hydraulic press component mode, greatly reduce operative employee's labour intensity; 2) improve component and press-fit precision, cross axle body axle journal cylindrical, cross axle bearing shell cylindrical, flange yoke earhole three coaxial line can be realized; 3) the utility model tool structure is simple, is convenient to disassembling section.
