The content shown, understands for those skilled in the art and reads, being not limited to this utility model enforceable restriction bar
Part, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size, do not affecting
Under effect that this utility model can be generated by and the purpose that can reach, all should still fall in the technology disclosed in this utility model
In the range of Rong get Neng is contained.Meanwhile, in this specification cited as " on ", D score, "left", "right", " middle " and " one "
Deng term, be merely convenient to narration understand, and be not used to limit the enforceable scope of this utility model, its relativeness
It is altered or modified, is changing under technology contents without essence, when being also considered as the enforceable category of this utility model.
In order to describe this utility model in detail, illustrated by following embodiment:
Embodiment 1
Light target in school shown in 1,2 with reference to the accompanying drawings, including light target bracing ring 1, bracing ring 1 is a circular housing, circle
3 groups of regulation screws are arranged in the outer of shape bracing ring 1 housing, and often group regulation screw includes a homophony screw 2 and auxiliary fine setting spiral shell
Nail 3, is correspondingly arranged at the two ends of a certain diameter of bracing ring 1 with group homophony screw 2 and auxiliary micrometer adjusting screw 3.3 homophony screws 2
Mutual angle is 90 °, 135 °, 135 °.
The center of bracing ring is combined with centre hole axis 4, interference fit bracing ring 1 on centre hole axis 4, on centre hole axis 4 also
Interference fit ball bearing 5, ball bearing 5 and one of them end contact of bracing ring 1, the external rotating of ball bearing 5 is joined
Closing rotary support 6, rotary support 6 is a loop configuration, and rotary support 6 can be in ball bearing 5 external rotating.Rotary support 6
On fix 1 indicator bracket 8 by screw 7, indicator bracket 8 is tangent with rotary support 6, and the end of indicator bracket 8 fixes percentage
Table 9.
The inside of bracing ring 1 is additionally provided with balancing weight 10, balancing weight 10 and centre hole axis 4 interference fit.Auxiliary micrometer adjusting screw 3
Shell end through bracing ring 1 contacts with balancing weight 10.
Homophony screw 2 is connected with bracing ring 1, and homophony screw 2 includes homophony pole, long adjusting rod and minor pole.Support
Being fixed with homophony pole on circle 1, the threaded long adjusting rod of free end of homophony pole, the threaded minor of long adjusting rod saves
Bar, long adjusting rod is more than the pitch threadeded of long adjusting rod and minor pole with the pitch threadeded of homophony pole.
The end thread of homophony screw (minor pole) connects protective cap 11.
Centre hole axis 4 end face is higher than bracing ring 1 end face, and bracing ring 1 end face herein is the one end not installing rotary support 6
(seeing Fig. 2).For coordinating transparent accessory 12, transparent accessory 12 arranges scale (seeing Fig. 5).The transparent accessory of the present embodiment
12 select foliated glass, and foliated glass coordinates at centre hole axis end face.
Shown in accompanying drawing 3,4, the when of use, install light target in the school of the present embodiment according to said structure, then
Multiple (according to detection requirements set number and distance) light target is put in the central siphon needing to detect centering.
What is called finds out the center line of shafting of marine propuision system exactly in looking for.Stern tube 13 is initially blank, needs processing
After, then bearing 14 is installed.Need to determine allowance and Working position accurately before processing it is necessary to utilize light target as measurement
Instrument, finds out the position of center line of shafting.Stern tube 13 after processing needs to check machining accuracy the most up to standard, at this moment remains a need for
Utilize light target and collimating telescope.During inspection, light target is arranged as it is shown on figure 3, light target 0 is as basic target, determines measuring basis line,
After light target 01 05 finds the center in cross section, place by dial gauge, collimating telescope 15 reads itself and measuring basis respectively
The deviation up and down of line.When deviation value is in the range of standard-required, i.e. prove that processing is qualified.Equally, after bearing 14 is installed,
After checking that bearing is installed by similar method, center line of shafting whether conformance with standard requirement.Light target is arranged and is seen accompanying drawing 4.
Concrete single light target uses:
By three homophony screws 2, light target is supported in central siphon.The end thread of homophony screw 2 (minor pole) connects
Protective cap 11, protective cap 11 material is lead, and material is soft compared with steel and bidery metal.In protective cap 11 can protect the central siphon of detection centering
Wall is not scratched, and threaded connection place can also trim lengths.Owing to the central siphon internal diameter of diverse location is not of uniform size, first rotate long tune
Pole and the connection screw thread of homophony pole, owing to pitch is relatively big, adjustable range is relatively big, is fixed in central siphon to be detected.By
Light target in the present embodiment arranges 3 homophony screws 2,4 homophony screws of the most existing part, has bigger operation empty
Between.Then by the contact internal walls of the test side of dial gauge 9 Yu central siphon to be detected, indicator bracket 8 is then rotated, due to rotary support
6 rotatable, ball bearing 5 is added in inside, and relatively primitive rotary support 6 directly coordinates with centre hole axis 4, increase quality of fit
And service life.Slowly rotating when, dial gauge 9 concomitant rotation, along with rotation, observe the data on dial gauge 9, reading
The when of bigger, stopping operating, regulate the connection screw thread of long adjusting rod and minor pole, owing to pitch is less, adjustable range is relatively
Little, it is also possible to by regulation auxiliary micrometer adjusting screw or the connection screw thread of regulation protective cap 11 so that the reading on dial gauge 9 becomes
To in 0.The most slowly rotate indicator bracket 8, again adjust each to adjust the length of screw according to the reading of dial gauge 9.Repeatedly adjust
Joint, until dial gauge 9, when the difference of reading of all directions is about 0, i.e. regulates complete.
Then the when of light target work, can be according to the scale reading on sheet glass, there is shown the centrage of position
Skew, carry out next step adjust.
Embodiment 2
Seeing embodiment 1, homophony pole is slightly different with the connection of bracing ring.
Bracing ring is provided with groove, and homophony pole is placed in groove through the housing of bracing ring, and in groove, card sets housing screw, passes through
Housing screw compresses homophony pole.The when of regulation, housing screw is unclamped, homophony pole is selected suitable position, in rotation
Tight housing screw.This structure is suitable for regulating on a large scale the size of main regulation screw.
Above-described embodiment only illustrative principle of the present utility model and effect thereof are new not for limiting this practicality
Type.Above-described embodiment all can be carried out by any person skilled in the art under spirit and the scope of the present utility model
Modify or change.Therefore, art has usually intellectual such as without departing from the essence disclosed in this utility model
All equivalences completed under god and technological thought are modified or change, and must be contained by claim of the present utility model.
