As shown in Figure 1 to Figure 3, the concrete structure of this crankshaft detection base comprises: base plate 1 and be laid in the way block 2 at base plate 1 end face two ends respectively, and the skateboard component be laid in the middle of way block 2 and be laid in the V-block 3 on way block 2 top.Wherein, the lining roller of V-block 3 and skateboard component works in different operations, and by adjusting bolt steadily to switch, when the stroke of lining roller will be guaranteed to hang on bent axle and hang bent axle in retraction way block (under) portion, do not collide with crankshaft journal surface, measure when crankshaft main journal is beated and can rise to enough height again, be convenient to two independent supporting crankshaft axle journals of lining roller, thus realize being paid by crankshaft main journal surface and the V-block slip that forms of surface change the rolling that (change) become surperficial and two the lining roller cylndrical surface of crankshaft main journal to form and paying.The design of this crankshaft detection base lifts and hangs two supporting V-blocks used, ensure the lifting of bent axle during platform measuring and hang and (comprise the safety of this assembly two lining rollers and the protection of crankshaft main journal working surface) safely, making checkout procedure reach safety requirement; And be used for supporting crankshaft main journal by two groups of lining rollers of design skateboard component, with hand, bent axle steadily being rotated when measurement Large Crankshaft main journal beats project becomes possibility, makes measurement lighter.In addition, by arranging screw adjustment mechanism, make bent axle lift, hang operation and measure main journal beat project operation switching by adjustment bolt easily realize, ensure that Large Crankshaft platform measuring main journal beat project time, lifting, to hang and measurement reaches safety, laborsaving, thus make measurement result more accurate.
Base plate 1 is rectangular plate, and end face two ends offer respectively by bolt and the hard-wired tapped hole of way block 2.
As shown in Figure 5, way block 2 be a pair inverted T-shaped piece, T-shaped head is fixedly mounted on the end face two ends of rectangular base plate 1 respectively by bolt.The T-shaped bar relative inner of pair of guide rails block 2 offers the guide groove 21 vertical with base plate 1 respectively, and top offers respectively by bolt and the hard-wired tapped hole of V-block 3.
Skateboard component comprises: slide plate 41, lining roller 42 and adjustment bolt 43, as shown in Figure 6, the both sides of slide plate 41 extend the guide rail 44 with guide groove 21 adaptation of pair of guide rails block 2 respectively, top offers the roller bearing bore 45 running through both sides, front and back for a pair, as shown in Figure 4, a pair rolling bearing 47 is laid with respectively in each roller bearing bore 45, lining roller 42 is located in the middle part of supporting axle 46, supporting axle 46 two ends are laid in rolling bearing 47, rolling bearing 47 both sides are laid with circlip for hole 48 and circlip for shaft 49 respectively, the end face of slide plate 41 is stretched out at its top, for supporting crankshaft main journal, with hand, bent axle is steadily rotated when measurement Large Crankshaft main journal beats project and become possibility, make measurement lighter.The middle part of slide plate 41 offers the bolt adjustment screw 50 of vertical base plate 1, the bottom of bolt adjustment screw 50 is reserved with adjustment bolt and lays groove 51, the screw rod of adjustment bolt 43 is screwed in the bolt adjustment screw 50 of slide plate 41, slide plate 41 and lining roller 42 can be made to be elevated by the head rotating adjustment bolt 43, by arranging screw adjustment mechanism, make bent axle lift, hang operation and measure main journal beat project operation switching by adjustment bolt easily realize.In addition, the head side of adjustment bolt 43 offers the equally distributed stubborn rod aperture of multiple circumference, when rotating adjustment bolt 43, can rotate adjustment bolt, reach labour-saving object by stubborn bar.
V-block 3 is fixedly mounted on way block 2 top respectively by bolt; form the V-type groove lifting and hang bent axle to be detected; ensure the lifting of bent axle during platform measuring and hang and (comprise the safety of this assembly two lining rollers and the protection of crankshaft main journal working surface) safely, making checkout procedure reach safety requirement.The top of V-block 3 is also bolted with lifting bolt 31 respectively.
As shown in Figure 7 and Figure 8 (arrow represents bent axle sense of rotation), the concrete steps of detection are as follows:
1) two these crankshaft detection base 8 are placed on measuring table 5, first with adjustment bolt 43, slide plate 41 is turned down, guarantee to hang in the future bent axle back bush roller 42 not with tested bent axle 6 journal contact, then bent axle 6 is hung on (now bent axle only contacts with V-block, and does not contact with lining roller surface) on V-block 3.
2) slowly the slide plate 41 of two groups of supporting bases is heightened with adjustment bolt 43 again, guarantee that lining roller contacts (now bent axle does not contact with V-block) with tested crankshaft journal, two groups of bearing assembly slide plates are slowly adjusted with adjustment bolt, make tested crankshaft center line parallel with faceplate, turning crankshaft gently, namely carries out beating project survey by dial gauge 7.
3) after having measured, first with adjustment bolt 43, the slide plate 41 of two groups of supporting bases is turned down, guarantee lining roller 42 not with tested bent axle 6 journal contact (now bent axle only contacts with V-block, and does not contact with lining roller surface), then bent axle is hung on V-block bearing assembly.
This kind of Large Crankshaft detects the platform measuring that bearing assembly is not only applicable to Large Crankshaft, is equally applicable to the project survey of beating of other overweight revolving parts, but corresponding height parameter will carry out design alteration.
To sum up, this crankshaft detection base is simple and reasonable, when ensureing platform measuring by design lifting two supporting V-blocks used bent axle lifting and hang and (comprise the safety of this assembly two lining rollers and the protection of crankshaft main journal working surface) safely, and by design two groups of lining roller wheel bearing crankshaft main journals, make measurement main journal beat project time bent axle steadily can rotate and become possibility, by arranging screw adjustment mechanism, bent axle is lifted, hang operation and measure main journal beat project operation switching by adjustment bolt easily realize, can ensure Large Crankshaft platform measuring main journal beat project measurement result accurately and efficiency all high.
Be only several specific embodiment of the present invention above, but the present invention is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
