The invention relates to the technical field of
mechanical equipment, and discloses double-sided
machining and
grinding equipment for mechanical parts. The double-sided
machining and
grinding equipment comprises a fixed stand, a movable lifting mechanism and turnover mechanisms, wherein the movable lifting mechanism is arranged at the upper end of the interior of the fixed stand, and the turnovermechanisms are arranged on the
left wall and the right wall of the interior of the fixed stand. According to the double-sided
machining and
grinding equipment for the mechanical parts, a first hydraulic
telescopic cylinder is started to enable a fixing support to descend, then a grinding disc grinds the upper surfaces of parts fixed in a fixing frame,after the upper surfaces are ground, the firsthydraulic
telescopic cylinder lifts the fixing support, meanwhile, a second hydraulic
telescopic cylinder and a third hydraulic telescopic cylinder are started to enable the fixing frame to ascend bya certain height, a second
servo motor is started to overturn the fixing frame, then the fixing frame descends through the hydraulic telescopic cylinders to the upper surface of a fixed lifting plate,and then the parts are subjected to back face grinding without being detached or overturned manually, so that the grinding efficiency and the working safety are improved.
