Precision assemble calibrating lifting device

Abstract

The invention discloses a precision assemble calibrating lifting device, which is composed of a movable base, an end mirror bracket and a movable lifting mechanism. The end mirror bracket is mounted above the movable base, a movable beam mechanism is mounted at one side of a pushing handle of the movable base, and the movable lifting mechanism is placed on a bottom plate in the movable base; the movable base is pushed to a work station and truckles of the movable base are locked, an initial work station of the movable lifting mechanism is adjusted so as to position the movable lifting mechanism under a calibrating position of the end mirror bracket, the movable lifting mechanism is located, and calibration objects are placed on a working disk in the end mirror bracket. The movable liftingmechanism is moved to next work station after a fast lock is released. The precision assemble calibrating lifting device uses the structure form of the lifting device rationally, so that installationof guide rails and use of complex hydraulic drive devices are used; and the precision assemble calibrating lifting device is simple in structure, small in volume, high in location precision and excellent in continuity of motion, realizes continuous high-efficiency calibration works in complex environments and can precisely calibrate work pieces.

Description

technical field [0001] The invention belongs to the technical field of mechanical design and manufacture, and relates to a precision calibration lifting device for mechanical calibration. Background technique [0002] Whether it is in engineering construction or in the large-scale equipment manufacturing industry, the calibration of parts and components is the key link for the smooth completion of the entire project, and the calibration has a strong restrictive effect on its progress and performance. In the prior art, most of the elevating devices installed in the school adopt a sliding guide rail type structure and hydraulic drive. [0003] Chinese patent 200720093819 discloses a movable center pin positioning elevating frame. This movable center pin positioning elevating frame uses sliding guide rails to complete the lifting task of the device, but it has high requirements for the manufacturing and assembly accuracy of the guide rails. And the guide rail is not retractabl...
