Embodiment
Embodiments provide a kind of shaft coupling installation alignment device, to need the contradiction between larger installation operating space when the size alleviating equipment is more and more less and dial gauge is installed at the scene.
Technical scheme in the present invention is understood better in order to make those skilled in the art person, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, should belong to the scope of protection of the invention.
Please refer to Fig. 1-7, embodiments provide a kind of shaft coupling installation alignment device.The alignment device provided comprises support member 100, probe 200 and elastic component.
Wherein, support member 100 is generally strip piece, and in use, the length direction of support member 100 is the abutting direction of two plain flange dishes of shaft coupling.Support member 100 is provided with pilot hole 113.Probe 200 is arranged at pilot hole 113, and can move along pilot hole 113.The bottom surface of support member 100 is plane, and end face is top reference face.The bottom surface of support member 100 and end face are all perpendicular with the moving direction of probe 200.Usually, probe 200 slides in pilot hole 113.
The outer two ends stretching in pilot hole 113 respectively, two ends of probe 200.The bottom of probe 200 is contravention 230, and the bottom surface of support member 100 is surface of contact, and contravention 230 is coplanar in the first plane with the bottom surface of support member 100.Probe 200 is provided with the first scale section, first scale section comprises the first zero graduation line and is distributed in the first positive number scale area and the negative scale area of the first zero graduation line both sides, and the first positive number scale area, the first zero graduation line and negative scale area distribute successively along the moving direction of probe 200.With standard rule subclass seemingly, no matter be the first positive number scale area, or negative scale area, the distance of distance the first zero graduation line is far away, and so the absolute value of ruler subscript number is larger.In the embodiment of the present invention, the top end face of the first zero graduation line and pilot hole 113 is coplanar in the second plane.Usually, the end face of support member 100 and the top end face of pilot hole 113 coplanar, therefore the end face of support member 100 and the first zero graduation line also coplanar.
Elastic component is arranged in pilot hole 113.Elastic component is generally spring 400.Elastic component is connected with probe 200 at the moving direction of probe 200.The effect of elastic component is to apply restoring force to probe 200, to ensure that probe 200 is in original state.Operating personnel press down or on carry probe 200 and realize probe 200 and move relative to pilot hole 113, can compress or draw springs, after external force is removed, under the restoring force effect of elastic component, probe 200 is reset to original state simultaneously.For the ease of operation, the top of probe 200 is provided with operation carrying handle 220, so that the operation to probe 200.
The course of work of the alignment device that the present embodiment provides is described below in conjunction with Fig. 7, specific as follows:
Be placed on the bottom surface of support member 100 on the wheel rim of plain flange dish 500, moveable support 100 makes probe 200 relative with the wheel rim of plain flange dish 600.This process, operating personnel carry or press down probe 200 on needing and probe 200 is moved relative to pilot hole 113, and then contravention 230 is contacted with the wheel rim of plain flange dish 600.The alignment device that the present embodiment provides is in original state, and contravention 230 is in same plane with the bottom surface of support member 100, and the end face of the first zero graduation line and support member 100 is coplanar.Due to the moving direction of probe 200 and the bottom surface of support member 100 mutually vertical, therefore, operating personnel press down or on when carrying probe 200, scale mark can depart from the end face of support member 100, and then makes another scale mark of the first scale area and the either flush of support member 100.Now operating personnel read the scale reading of the either flush of the first scale area and support member 100 by the visual angle flushing in support member 100 end face, and this reading is the displacement of probe 200.Because plain flange dish 500 is identical with the diameter of plain flange dish 600, therefore the displacement of above-mentioned probe 200 be plain flange dish 500 and plain flange dish 600 axis between in the distance of probe 200 moving direction, operating personnel can implement the centering work of shaft coupling according to this distance.
Known by the above-mentioned course of work, the alignment device that the present embodiment provides can complete assembling outside the venue, operating personnel only need the position regulating support member 100 in use, and then the bottom surface of support member 100 is contacted with the wheel rim of plain flange dish 500, the contravention 230 of probe 200 contacts with plain flange dish 600, by the reading to the first scale section and support member 100 either flush scale, plain flange dish 500 and the axial line distance of plain flange dish 600 can be obtained, then implement the centering work of shaft coupling according to this distance.Visible, the alignment device that the present embodiment provides can avoid in-site installation.And the embodiment of the present invention can realize and distance adjustment between plain flange dish 500 and plain flange dish 600 contact site, and then make alignment device more can adapt to the less device space.In summary, the alignment device that the present embodiment provides can alleviate the size of equipment more and more less and dial gauge is installed at the scene time need between larger installation operating space contradiction.
