Description
Technical field
The utility model belongs to technical field in optical axis school, specifically relates to frock in a kind of optical axis school, is applied to when carrying out in school optical axis, and utilizes axle system periphery, measures frock in skew, tortuous school.
Background technology
In shipbuilding technology field; some diameters often will be used less; the elongated optical axis that length is longer; a problem is just there will be in time using these elongated optical axises; that is exactly that elongated optical axis can produce very large amount of deflection usually; cause aiming at installation, therefore need to carry out in straight line school elongated optical axis when mounted.
Optical axis and mounted stern tube shaft carried out offset, in tortuous school, by jackshaft and stern tube shaft in alignment, its objective is and intermediate bearing is positioned on the straight line at stern tube shaft place in straight line school.The conventional method that skew in optical axis school, tortuous value are measured is needing the opposite ends of the axle in school to install corresponding frock flange, and arrange dial gauge in the appropriate position of flange, reads the tortuous value of skew according to the reading of dial gauge.
But pointer drift when adopting existing frock flange to there will be on the one hand measurement, the problem that measuring result error is larger, need on the other hand needing the two ends of the axle in school all to install corresponding frock flange, method relative complex in school, and cost is higher.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides frock in a kind of optical axis school, without the need to additionally making frock flange, adopts new measuring method, quick, simple and easy, skew when obtaining centering of shafting exactly, tortuous value.
The technical solution of the utility model is as follows:
Frock in a kind of optical axis school, is characterized in that: in described optical axis school, frock comprises dial indicator bracket 1, first dial gauge 2 and the second dial gauge 3; Described dial indicator bracket 1 is formed by fixedly connecting by a long corner angle is vertical with minor face angle steel, described long corner angle has two holes along its length at a certain distance, the first described dial gauge 2 and the second dial gauge 3 are fixed on dial indicator bracket through two above-mentioned holes, make the pointer of the first dial gauge 2 and the second dial gauge 3 touch the periphery of axle 6 to be measured; The end winding support of described minor face angle steel connects semicircle fixed block, to be fixedly connected with to be fixedly connected on the periphery of reference axis 7 by described dial indicator bracket 1 with another semicircle fixed block 4 by securing member 5.
In a preferred technical scheme, described securing member is bolt.
Technical advantage of the present utility model is as follows:
(1) the utility model is without the need to additionally making frock flange, has saved production cost.
(2) the utility model requires lower to the making of dial indicator bracket, and former dial indicator bracket has higher requirement to perpendicularity.
(3) the utility model metering system is extremely simple, time saving and energy saving.
(4) the utility model computational methods are also comparatively simple, can obtain skew required in school, tortuous value fast.

Detailed description of the invention
Frock in a kind of optical axis school of the present utility model is described in detail below in conjunction with Figure of description 1 ~ 3 and detailed description of the invention.
One, measuring method of the present utility model:
(1) in optical axis school, frock is made up of dial indicator bracket, two dial gauges.
(2) adopt clamp form, dial indicator bracket is fixed on the periphery of reference axis.
(3) in the appropriate location of reference axis length direction, on periphery dial indicator bracket being fixed on reference axis.
(4) pointer of two dial gauges is touched the periphery (see accompanying drawing 1 ~ 2) that axle surveyed by band.
(5) suppose that the horizontal range between dial gauge 1, dial gauge 2 is L.
(6) rotation base fiducial axis, the reading meeting respective change of dial gauge, rotates in the process of whole circle, records the reading at diverse location place dial gauge 1, dial gauge 2, be respectively: 1. go up, 2. go up; 1. under, 2.; 1. left, 2. left; 1. right, 2. right.
The acquisition of two, skew, tortuous value: (see accompanying drawing 3):
(1) upper and lower deviant:
Deviant 1=(1. go up-1. under)/2
Deviant 2=(2. go up-2. under)/2
Downward shift value=(deviant 1+ deviant 2)/2
=[(1. go up-1. under)+(2. go up-2. under)]/4
(2) left and right deviant:
In like manner, left and right deviant=[(1. left-1. right)+(2. left-2. right)]/4
Jackshaft and stern tube shaft carry out in school, and the version of jackshaft is shown in accompanying drawing 3.
(3) upper and lower complications value:
Tortuous value 1=(1. go up-2. go up)/L
Tortuous value 2=(1.-2. under)/L
Upper and lower complications value=(tortuous value 1+ complications value 2)/2
=[(1. go up-2. go up)+(1.-2. under)]/2L
(4) left and right complications value:
In like manner, left and right complications value=[(1. left-2. left)+(1. right-2. right)]/2L
Technical advantage of the present utility model is as follows:
(1) the utility model is without the need to additionally making frock flange, has saved production cost.
(2) the utility model requires lower to the making of dial indicator bracket, and former dial indicator bracket has higher requirement to perpendicularity.
(3) the utility model metering system is extremely simple, time saving and energy saving.
(4) the utility model computational methods are also comparatively simple, can obtain skew required in school, tortuous value fast.
For certain public affair ship, jackshaft and stern tube shaft carry out in school, before installation shaft coupling, treat school axis and reference axis carries out in school.Application the utility model carries out in school, obtains skew, tortuous value fast, axle system is constructed and reaches good effect.
