Abstract
The checking center device without the flange axis includes the measure arm, the cutting sleeve, the installment bolt and the dial indicator. The cutting sleeve is made up of the crust and the inner cutting sleeve which is installed in the crust and fixed with it. The open mouth with ear plate fixed on both sides is set in the cutting sleeve. The screw is installed on the ear plate of one side which supports the other ear plate by the rotating installment screw, so the inner diameter of the cutting sleeve is made big. The cutting sleeve is two which are set on one end of the measuring arm in a setting distance; the dial indicator is installed in the other end of the arm. The invention has the simple structure. So the device can promise the round degree of every parts of the axis and the same axis degree.
Description
Technical field
The present invention relates to machinery and install, particularly relate in the non-flanged axle class school that boats and ships axle, rudder system install and installing.
Background technology
Install at the scene of boats and ships axle, rudder system, in can't blue axle class school being a difficult problem in the puzzlement shipbuilding process.Because axle system belongs to the running part of Large-Scale Equipment, can the whether firm quality that reaches the centering situation of installation of connection is directly connected to high-level efficiency, stable operation.Particularly can't blue axle tie up to require in dimensional accuracy in the connection and the school all very high.
Device was owing to the insufficient strength of gage beam in the device in the school of Cai Yonging in the past, and when dial gauge was fixed on the gage beam, gage beam often produced moderate finite deformation naturally, and giving works in the school brings sizable difficulty.In the school, in the process, need select two to measure the cross section simultaneously with the mode of pulling shaft.Because axle can't be fixed, so be easy to generate irregular vibration during pulling shaft, make its change in location, giving works in the school has brought uncertainty.Device in the school adopts bolt to be connected again with axle, when shifting one's position survey measurements, because the dynamics of each fastening bolt is difficult to keep evenly, causes gage beam to have nothing in common with each other at the measurement state of diverse location, so produce bigger measuring error.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of simple in structurely, can guarantee to install in the non-flanged axle class school of high precision centering.
The technical scheme that adopts is:
Non-flanged axle class is installed in the school, comprises gage beam, cutting ferrule, mounting screw and dial gauge.Described cutting ferrule is made up of cutting ferrule shell and interior cutting ferrule, interior cutting ferrule is contained in the cutting ferrule shell and with the cutting ferrule shell and fixes, cutting ferrule is provided with place's opening, both sides in opening respectively are installed with otic placode, mounting screw is mounted in it on the otic placode of opening one side, the rotation mounting screw is replaced on the otic placode of opening opposite side it, can the support of cutting ferrule internal diameter is big, described cutting ferrule is two, be fixedly connected on an end of gage beam respectively with the distance of setting, dial gauge is contained in the other end of gage beam, and formation can't be installed in the blue axle school.
Said fixing is connected and is provided with the reinforcement that connects two cutting ferrules between two cutting ferrules on the gage beam.
The above-mentioned interior cutting ferrule that is installed in the cutting ferrule shell adopts the brass manufacturing for preventing scuffing axle class surface.
Above-mentioned gage beam is to adopt not only proof strength, but also alleviate the joist steel formula structure of own wt.
The present invention is simple in structure, and is workable.Use in this non-flanged axle class school and install, can be good at guaranteeing that axle is the technical requirement of circularity and right alignment between each parts.

Embodiment
Non-flanged axle class is installed in the school, comprises gage beam 1, cutting ferrule 2, mounting screw 4 and dial gauge 8.Gage beam adopts joist steel formula structure, not only proof strength, but also alleviate own wt, also avoid the gage beam distortion and cause measuring error.Cutting ferrule 2 is made up of cutting ferrule shell 5 and interior cutting ferrule 6; interior cutting ferrule 6 is made for H62 brass; its objective is that protection axle class surface is injury-free; cutting ferrule 6 is contained in the cutting ferrule shell 5 fastening by screw; cutting ferrule 2 is provided with place's opening; both sides in opening respectively are installed with otic placode 7, and mounting screw 4 is mounted in it on the otic placode of opening one side, and rotation mounting screw 4 is replaced on the otic placode of opening opposite side it.Described cutting ferrule 2 is two, is fixedly connected on an end of gage beam 1 respectively with the distance of setting, and is provided with the reinforcement 3 that connects two cutting ferrules between two cutting ferrules 2, and dial gauge 8 is contained in the other end of gage beam 1.
This device in the process, will be sleeved on the side shaft 10 by cutting ferrule 2 in the diaxon school, and will be shown in Figure 3.The internal diameter of cutting ferrule 2 is slightly less than the external diameter of axle 10, with mounting screw 4 that cutting ferrule 2 supports are big, after axle 10 is packed in the cutting ferrule 2, mounting screw 4 is unclamped in rotation, cutting ferrule 2 just can rely on self intrinsic, constant convergent force and axle 10 to be fixed together, this structure has been avoided because of device needs to rotate the change that causes gage beam 1 and axle 10 relative positions, and then reduces measuring error and improved the practical value of installing.To contact with axle 9 at two dial gauges 8 of gage beam 1 other end, can realize installing in all non-flanged school of diaxon class part.
