Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1, Figure 2 and Figure 3, the axis fast-positioning device of this large scale equipment, including equipment shaft flange 1, it is described
Axis fast-positioning device further includes the pedestal 2 with platform 21, the pedestal 3 for being fixed on 21 upper surface of platform and is slidably arranged in
Bracket 4 on pedestal 3, the pedestal 2 are fixed on equipment shaft flange 1, are offered on the side wall of the pedestal 2 and equipment method of principal axes
The cone tank 22 of blue 1 coaxial line, the bracket 4 have a sleeve 41, in the sleeve 41 with fixing sleeve 5 and fixing sleeve 5 it is outer
There is gap 1 between circumferential surface and the inner peripheral surface of sleeve 41, be fixed with projectoscope 7 in the fixing sleeve 5, the projectoscope 7
It the tapered shape in tail portion and is resisted against on the vertex of cone tank 22, circumferentially opens up that there are four fixed on the outer peripheral surface of the fixing sleeve 5
Position slot 51, four locating slots 51 are circumferentially evenly arranged, and are circumferentially threadedly coupled on the sleeve 41 there are four adjusting screw 8,
Four adjust screws 8 and correspond with four locating slots 51 and adjust the one end of screw 8 to extend to locating slot 51 interior and be resisted against
On fixing sleeve 5, and adjusts screw 8 and be located between the one end in locating slot 51 and the cell wall of locating slot 51 with gap 29.
First the present apparatus is mounted on equipment shaft flange 1, the tapered shape in the tail portion of projectoscope 7 and is resisted against cone tank 22
The light and 1 coaxial line of equipment shaft flange for issuing projectoscope 7, are installed on the reference point location of equipment positioning
Light target adjusts the position of light target cross centre line, is allowed to be overlapped with the cross hairs center that the projection of projectoscope 7 comes, then equipment axis
Flange 1 rotates 180 °, since the optical axis of projectoscope 7 at this time is not overlapped generally with equipment axis, therefore the projection of projectoscope 7 after turning 180 °
Cross hairs center out is not overlapped with the cross hairs center of light target, then writes down light target cross hairs center and projectoscope 7 respectively
The deviation of cross hairs center in the horizontal direction and the vertical direction adjusts the position of projectoscope 7 by turning adjusting screw 8,
The presence in gap 29 makes it possible to adjust the position of projectoscope 7 by turning adjusting screw 8, and fixing sleeve 5 moves in gap 1
It is dynamic then to press the optical axis of at this time projectoscope 7 so that 7 cross searching of projectoscope is fallen on the general position of light target upper deviation value,
Light target position is adjusted, light target cross hairs center is overlapped with 7 cross hairs center of projectoscope again, then turns equipment shaft flange 1 again
180 ° dynamic, whether the two cross hairs centers of inspection are overlapped, and two cross hairs centers do not have too large deviation at this time under normal circumstances, such as still
It is not overlapped the position for continuing to adjust projectoscope 7 according to the above method.
As shown in figure 3, radially offering threaded hole on the outer peripheral surface of the fixing sleeve 5, the screw hole has lock
The positioning screw 10 of tight projectoscope 7.
As shown in figures 1 and 3, the upper surface of the pedestal 3 offers open at one end, the branch of sliding slot 31 and sliding slot 31
The lower end of frame 4 is slidably arranged in sliding slot 31, and the upper surface of the platform 21 is fixed with the opening of closing 31 one end of sliding slot
