Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

With reference to Fig. 1, Fig. 2, the structure of the utility model right alignment tester is, be included in disk chi 7 and be provided with angle index line 9 along circumference, disk chi 7 upper surfaces are connected with horizontal slide rule 5 by clamping screw 8, horizontal slide rule 5 is provided with horizontal slide rule scale mark 6, in the vertical chute of the upper surface of horizontal slide rule 5 probe base 4 is installed, and probe tube 2 is installed on the probe base 4, the top of probe tube 2 is provided with laser diode 1, and the middle part of probe tube 2 is provided with the gauge tap 3 of laser diode 1; The lower surface of disk chi 7 is provided with ferromagnetism base 10 with one heart, in the axle center positioning head axle center hole of ferromagnetism base 10 spring 11 is installed.

Adorn three lithium batteries with probe base 4 in the probe tube 2, can in the chute of horizontal slide rule 5, be free to slide.Is that the test of coaxiality deviation on any direction in 360 ° can be finished in the rotation of disk chi 7 upper surfaces in the center by adjusting horizontal slide rule 5 with clamping screw 8, make angle be accurate to per 0.5 degree according to the angle index line 9 on the disk, for next step adjustment provides the adjustment angle-data.

During the utility model work, at first utilize axle to be measured to add the center pit that leaves man-hour, the spring 11 that the axle center positioning head is built-in is put into center pit centering, the magnetic of using ferromagnetism base 10 can steadily be fixed to axle head to tester, in the axle center positioning head compression spring 11 withdrawal cavitys, realized the location of tester axle centering at this moment.In the draw-in groove of horizontal slide rule 5, slide probe tube 2 to realize moving of rectilinear direction, rotate horizontal slide rule 5 to realize locking position, can realize this direction ranging by read level slide rule scale mark 6 values, use the light beam that laser diode 1 sends this moment and can on another axle, form little red hot spot, distance by the measurement axis limit, can measure the deviate of diaxon, realize the quantification of coaxiality deviation.Is that the test of coaxiality deviation on any direction in 360 ° can be finished in the rotation on disk chi 7 surfaces in the center by adjusting horizontal slide rule 5 with clamping screw 8.In addition, horizontal slide rule also can slide in disc face, to realize the test of large diameter axle right alignment, in order to widen the test specification of tester, can finish the coaxality measurement problem of the many kinds of diameters of axle of φ 10-280mm.Because what tester was selected for use is the laser diode irradiation, hot spot is not dispersed in the distance in 10m, therefore can finish the measurement and the debugging problem of the diaxon right alignment of a span between 100-1000mm.

As the right alignment test implementation example 1 among Fig. 3, because the axial line of the diaxon of testing (axle 1 to be measured and axle 2 13 to be measured) is parallel, be that axial end is parallel, only need finish test to opposite shaft edge offset distance to tester with vertical direction in the horizontal direction this moment, can obtain opposite shaft in the horizontal direction with the coaxiality deviation of vertical direction, only need can finish debugging during debugging in the corresponding distance of this both direction adjustment.

As the right alignment test implementation example 2 among Fig. 4, because the axial line of the diaxon of testing (axle 1 to be measured and axle 2 13 to be measured) is uneven, promptly axial end is angled.The first step of the method for testing of this moment is earlier according to two steps described in the embodiment 1, realize that the diaxon axial end center of circle is on the intersection of surface level and vertical plane, do not had coaxiality deviation by diaxon on the surface level direction in the diaxon axial end center of circle this moment again, only need add the adjusting that pad can be realized the axial end collimation on vertical direction.
