Accompanying drawing explanation
Fig. 1 is the one-piece construction schematic diagram of a kind of horizontal irradiation target of the utility model.
Fig. 2 is the embodiment schematic diagram of a kind of horizontal irradiation target of the utility model.
Embodiment
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, the utility model is further elaborated.
As shown in Figure 1, a kind of horizontal irradiation target, this horizontal irradiation target comprises: base 1, seat board 2, extension spray lance 3, milscale 4 and irradiation target 5.
Wherein, seat board 2 is arranged on base 1 center, and is fixedly connected with base 1.Extension spray lance 3 is arranged on seat board 2 center, is connected with seat board 2.Milscale 4 is connected with extension spray lance 3 top.Irradiation target 5 is connected with milscale 4 top.
In the present embodiment, be provided with threaded connector 21 in seat board 2, extension spray lance 3 is fixedly connected with seat board 2 by threaded connector 21.Be provided with threaded connector 31, tail joint 32 at extension spray lance 3 top, threaded connector 31 is connected with tail joint 32, and this tail joint 32 is connected with milscale 4, realizes the connection of extension spray lance 3 and milscale 4.Be provided with joint 41, little axle 42 and clamping nut 43 successively at milscale 4 top, irradiation target 5 is connected with milscale 4 by clamping nut 43, little axle 42 and joint 41.
Be provided with the opening 11 that cross section is inverted V-shaped in bottom base 1, opening 11 mates fixing with the cylindrical of rudder stock or rudder pintle.The center superposition of the cylindrical of the center of opening 11 and rudder stock or rudder pintle.Level meter 6 is provided with in base 1 top center.
In the present embodiment, the cross section of opening 11 is isosceles inverted V-shapeds, and the angle of opening 11 is 120 °.Isosceles inverted V-shaped opening 11 in 120 ° of angles, base 1 can be made to reach best with the tangent degree of cylindrical of rudder stock or rudder pintle, thus the installation stability of be up to the standard irradiation target and rudder stock or rudder pintle is best.
The center of the cylindrical of the cross searching of irradiation target 5 and the center of opening 11, rudder stock or rudder pintle overlaps.
As shown in Figure 1 and Figure 2, the horizontal irradiation target of the one that the utility model provides, specific works principle is as follows:
In actual measurement concentricity process, the concentricity only needing the horizontal irradiation target of employing two can realize rudder stock, rudder pintle and rudder blade is measured.
When irradiation, by a horizontal irradiation target as A place, A place can be rudder stock or rudder pintle, by another horizontal irradiation target as rudder blade C place.According to the level meter 6 being placed on the horizontal irradiation target in A place, by fine setting base 1, proofreading quality is carried out to this horizontal irradiation target.According to the level meter 6 being placed on the horizontal irradiation target in B place, by the plane of finely tuning base 1, proofreading quality is carried out to this horizontal irradiation target.Thus guarantee the irradiation target 5 of each horizontal irradiation target and the cylindrical center superposition of rudder stock, rudder blade or rudder pintle.
In the present embodiment, rap the end face of the base 1 of horizontal irradiation target with objects such as wooden units, make the level meter 6 of horizontal irradiation target be in equilibrium state, thus ensure that the end face level of base 1 is in ground.
When after two that are in position A, C equal modulation levels of horizontal irradiation target, use Instrument for Straightness by the irradiation target center of two horizontal irradiation targets and Instrument for Straightness center point-blank.
In the present embodiment, milscale 4 is adopted to regulate the height of irradiation target 5.
Immediately, B place is moved to by being in the horizontal irradiation target that A goes out, B place can be rudder pintle or rudder stock, carries out proofreading quality again to this horizontal irradiation target, the error between the target center measuring the irradiation target of the horizontal irradiation target of target center and C place of the irradiation target of B place horizontal irradiation target immediately by Instrument for Straightness.
In the present embodiment, Instrument for Straightness is micr-alignment telescope, accuracy value is 0.02mm, error≤0.01mm in 40m focussing distance, (micrometer telescope has two microdrums to regulate telescope microdrum, horizontal direction and the vertical direction of the cross curve in telescope can be regulated respectively), make the cross curve in the irradiation target on the horizontal irradiation target of the central cross line observed from micrometer telescope and C heavy and, the irradiation target cross searching error Fx(lateral error on the horizontal irradiation target at B place is read by the scale of microdrum) and Fy(vertical error).Ship rule require rudder stock, rudder pintle and rudder blade lateral error, vertical error all≤0.3.
Although content of the present utility model has done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple amendment of the present utility model and substitute will be all apparent.Therefore, protection domain of the present utility model should be limited to the appended claims.
