PRESS WITH PRECESSING HEAD Russian patent published in 2005 - IPC

FIELD: assembling of precise units of instruments by pressing-in with use of calibrated effort, by riveting and expanding with use of precession tool.

SUBSTANCE: press includes П-shaped housing; adjustable table mounted in struts of housing and fixed to said struts by means of pins; power hydraulic cylinder with axial motion of rod; rotation drive of precession head; pumping station of hydraulic drive unit. Rotation drive of precession head includes electric motor and belt transmission. Power hydraulic cylinder is rigidly mounted on cross piece of housing and it carries plate on end of spring-loaded rod. Said plate supports two plungers spaced in parallel relative to axis of rod and spring-loaded relative to housing. Pulleys of belt transmission of rotation drive are mounted in casing. The last is secured to plate in such a way that driven pulley is mounted on spindle coaxially relative to rod of hydraulic cylinder and driving pulley is mounted on the same axis as shaft of electric motor placed in cross piece of housing. Driving pulley and shaft of electric motor are kinematically joined by means of other shaft whose one end is mounted in shaft of electric motor and whose other end is joined by means of sliding dowel with opening of supporting axle of driving pulley. Spindle of driven pulley is joined with precession head.

EFFECT: improved design providing enhanced rigidity and working accuracy of press.
