Abstract

The invention relates to the field of parts of a large electric motor horizontally-assembled device and in particular relates to a fine-adjustment floating device for horizontal assembly of a large electric motor. The fine-adjustment floating device comprises a base of which the middle part of the bottom surface stretches out of a locating key in a front-back direction, an up-down thin cylinder fixed at the upper side of the base, a linear guide rail fixed on the up-down thin cylinder in a front-back direction, a sliding base matched on the linear guide rail in a sliding manner, a sliding bottom plate fixed on the sliding base and provided with opposite elongated slots left and right, an adjusting base plate fixed on the sliding bottom plate, a locating taper pin vertically fixed on the adjusting base plate and matched with a machine base foot plate hole through insertion, and two pressure plates with right-angled Z-shaped longitudinal sections. According to the fine-adjustment floating device, the problems that a stator and a rotor are collided and an end cover cannot be assembled easily in the large electric motor horizontally-assembling process can be effectively solved at low investment cost, and the fine-adjustment floating device has good reference function for flexible and horizontal assembly of parts with high quality, large diameter, small gaps and high assembling precision requirement.

Description

technical field [0001] The invention relates to the field of large motor horizontal assembly device components, in particular to a large motor horizontal assembly fine-tuning floating device. Background technique [0002] The horizontal assembly of accessories with an aspect ratio (the ratio of the total length of the motor to the diameter of the stator and rotor) greater than 1:5 usually adopts the following two methods: [0003] 1.1 Fix the stator 16 on a stator fixing table, use the crane bow 19 to lift one end of the rotor 17, visually determine that the stator 16 and the rotor 17 are coaxial, and then move the truck along the axis until the end covers at both ends of the motor are assembled to complete the assembly. [0004] 1.2 First fix the stator 16, install a dummy shaft 18 through the stator 16 and fix one end of the rotor 17, and then move the suspension bow 19 for driving along the axis of the motor until the end covers at both ends of the motor are assembled...
