(5) embodiment
The present invention is further detailed explanation below in conjunction with accompanying drawing.
A kind of center of circular hole locating device 7 shown in Fig. 1 to 5, its formation comprises support 1 and the light target frame 2 of annular, support 1 is provided with four struts 11 that can adjust to external extension that are spacedly distributed around annular stent 1 central shaft, and the central shaft of every strut 11 all points to the center of support 1.Support 1 has a square frame 12, and support 1 four erection columns 13 that extend internally out are connected so that square frame 12 is fixed on the middle of support 1 with four angles of square frame 12.Light target frame 2 is installed on the support 1, has a longitudinal adjusting mechanism and lateral adjustment to be installed in 2 of support 1 and light target frames to regulate light target frame 2 in vertical or horizontal motion.
Longitudinal adjusting mechanism comprises a rectangular frame 4 and vertical adjusting screw(rod) 52, rectangular frame 4 is provided with two vertical guide grooves (43,44), vertical guide groove (43,44) be set on two vertical sides of described square frame 12, the upper horizontal edge of described square frame 12 is provided with the first longitudinal screw hole 14, the upper horizontal edge of described rectangular frame 4 is provided with the second longitudinal screw hole 42, described vertical adjusting screw(rod) 52 cooperates installation with the first longitudinal screw hole 14 and the second longitudinal screw hole 42, regulates vertical adjusting screw(rod) 52 and realizes that light target frame 2 moves in the vertical.
Lateral adjustment has a lateral adjustments screw rod 51, light target frame 2 is provided with two horizontal guide grooves (23,24), horizontal guide groove (23,24) be located on two transverse sides of described rectangular frame 4, the limit, left side of described light target frame 2 is provided with the first horizontal thread hole 41, the limit, left side of described rectangular frame 4 is provided with the second horizontal thread hole 22, described lateral adjustments screw rod 51 cooperates installation with the first horizontal thread hole 41 and the second horizontal thread hole 22, regulates lateral adjustments screw rod 51 and realizes that light target frame 2 moves in the horizontal.
The center of light target frame 2 is provided with circular the first through hole 21, the first through holes 21 and is arranged with a removable center target 3, and the center of center target 3 is provided with circular the second through hole 31, the first through holes 21 and the 31 coaxial settings of the second through hole.Wherein the second through hole 31 diameters are 0.5mm, in order in use accurately pass through for wire when the center superposition in the center of centre of location target 3 and bearing or the propeller boss 6 to be processed and employing backguy method.
The using method of utilizing center of circular hole locating device 7 to improve marine shafting parts installation accuracy is described below:
The first step is to determine the theoretical centerline axis 82 of axle system.Establish the benchmark light target at bow reference point 83, stern reference point 84 places, regulate light target its cross curve is centered close on the reference point.Then the optical axis of the light beam that emits of generating laser 81 is by the cross curve center on the basic target, and then optical axis namely is theoretical centerline axis 82.
Second step is at bearing or propeller boss 6 interior installing center of circular hole locating devices 7 to be processed in workshop.Center of circular hole locating device 7 is put in bearing or the propeller boss 6 to be processed, adjusted the outwardly directed length of strut 11, to allow center of circular hole locating device 7 be fixed on the inwall in bearing or the propeller boss 6 to be processed.
The 3rd step was the interior center superposition of center and the bearing of fine setting the second through hole 31 or propeller boss to be processed 6.At first hold inside caliper according to the theoretical internal diameter numerical value of bearing successfully with milscale, take inside caliper two contact jaws distance as benchmark, contact with the center of the second through hole 31 by contact jaw of inside caliper again, about the endoporus of another contact jaw of inside caliper and bearing or propeller boss 6 to be processed, contact up and down, the fine setting lateral adjustment makes about inside caliper with longitudinal adjusting mechanism, up and down distance the same after center and the bearing of the second through hole 31 or the center superposition in the propeller boss 6 to be processed, screw respectively the first set nut 91 and the second set nut 92 at this moment light target frame 2 fixed.
The 4th step was that bearing or propeller boss 6 to be processed aboard ship are installed.The position of adjusting bearing or propeller boss 6 to be processed is dropped on the theoretical centerline axis 82 of axle system the center of the second through hole 31, and namely the center line of bearing or propeller boss 6 to be processed overlaps with the theoretical centerline axis 82 that axle is.In this step, when adopting the backguy method to determine theoretical centerline axis 82 position of axle system, center target 3 is not torn open, to allow wire pass through.And when adopting the optical instrument method to determine the position of the theoretical centerline axis 82 that axle is, needs after the center of determining the second through hole 31 is dropped on the theoretical centerline axis 82 of axle system with these center target 3 dismountings in order to next parts are installed, because the footpath of the second through hole 31 is too small, light be difficult for by or during through this through hole, cause next parts to produce alignment error thereby reflection occurs light.
The using method of the parts installation accuracy of raising shipping rudder system in like manner.
Be necessary to be pointed out that at this above embodiment only is used for the utility model is further specified; can not be interpreted as the restriction to the utility model protection domain, the those of ordinary skill in this field can be made some nonessential improvement and adjustment to above embodiment according to essence of the present utility model.
