Abstract
The invention discloses a rotating-body static-balancing-instrument shaftless centering device. The device comprises a pedestal. A bearing platform is fixed to the pedestal. A vertical cylindrical through hole is arranged in the middle of the bearing platform. A hydraulic cylinder is fixed to a hydraulic cylinder pedestal in the middle of the through hole. A push rod of the hydraulic cylinder is connected to an arc spherical surface joint. A centering cone block is fixed to a top of the spherical surface joint. An upper portion of the centering cone block is a cone stage body and a lower portion is an annular cylinder. The annular cylinder is inserted into the through hole. A plurality of centering telescopic push rods are arranged on the bearing platform. The centering telescopic push rods comprise telescopic plates. A front shape of each telescopic plate matches with an outer wall shape of the centering cone block and the telescopic plates and the centering cone blocks are contacted and cooperated. A guiding shaft is fixed between a bottom surface of each telescopic plate and a top surface of the bearing platform. A front end of a compression spring is fixedly connected to the guiding shaft and a rear end is fixedly connected to a spring sleeve. The spring sleeve is fixedly connected to the bearing platform. A spring sleeve cover is fixed to a rear end of the spring sleeve. By using the above structure, detection precision of a detected object is increased.
Description
Technical field
The present invention relates to a kind of shaftless centralising device, particularly relate to the shaftless centralising device of a kind of Revolving body static balancing instrument.
Background technology
Revolving body static balancing instrument centralising device common is at present that detected rotary body is passed central shaft, utilizes upper and lower cone block to carry out and carries out centering to detected rotary body.As shown in Figure 4, the central shaft 12 that common center support system comprises lower cone block 14 and is connected with lower cone block 14, the top of central shaft 12 is connected with epicone block 13, and detected rotary body 11 is placed between epicone block 13 and lower cone block 14.This device is owing to there being very long central shaft, and frock bothers relatively, especially the detected rotary body of up to a hundred tons, and can encounter central shaft unavoidably when lifting affects accuracy of detection.And large tonnage static balancing instrument central shaft is also higher, this just requires that detected rotary body is mentioned by crane and exceeds central shaft, this adds increased the extra risk that drops.After detected rotary body is packed into central shaft, then be placed on above central shaft and rotary body by epicone block, epicone block and central shaft are slidably matched, and the gap be slidably matched also directly affects accuracy of detection.
Summary of the invention
The object of the invention is to the deficiency overcoming prior art, provide a kind of centering accurate, significantly decrease the shaftless centralising device of Revolving body static balancing instrument of the dangerous operations such as lifting.
In order to achieve the above object, the technical solution used in the present invention is:
The shaftless centralising device of a kind of Revolving body static balancing instrument of the present invention, it comprises hydraulic cylinder base, described hydraulic cylinder base is fixed with bearing platform, vertical columniform through hole is had in the middle of described bearing platform, hydraulic cylinder base in the middle of described through hole is fixed with hydraulic cylinder, the push rod of described hydraulic cylinder is connected with the sphere joint of arc, centering cone block is fixed with at described sphere joint top, described centering cone block top is cone table and bottom is ring-type cylinder, described ring-type cylinder is inserted in described through hole and can moves up and down in through hole, symmetrically in the horizontal direction on described bearing platform be furnished with many alignment telescopic push rods, many described alignment telescopic push rods with the axis of the push rod of hydraulic cylinder for axis of symmetry is arranged symmetrically with, each alignment telescopic push rod includes expansion plate, front end geometry and the described centering of described expansion plate are bored block outer wall shape and to be matched and both contact cooperation, the axis of guide is fixed with between the bottom surface and the end face of bearing platform of described expansion plate, the front end of Compress Spring and the axis of guide are fixedly linked and rear end and spring housing are fixedly linked, described spring housing and bearing platform are fixedly linked, spring upper shield is fixed with in described spring housing rear end, the described axis of guide can do stretching motion in the horizontal direction under Compress Spring and centering bore the effect of block on bearing platform.
The invention has the advantages that: structure is simple, decrease the expense making central shaft and epicone block.More convenient operation, ingeniously utilizes rotary body self gravitation, just can complete centering work after only rotary body need being positioned over bearing platform, significantly reduces dangerous operation such as lifting grade.Decrease mechanical tolerance clearance, improve the accuracy of detection of detected material.
