Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further details.
As shown in Figure 1, a kind of crankshaft grinding machine special fixture, comprises the flange terminal pad 1 being fixed on grinding machine, and described flange terminal pad 1 is provided with clamp body 2.
As shown in Figure 1, Figure 2, Figure 4 shows, described clamp body 2 is cuboid clamp body 2, described clamp body 2 leading flank right sides are provided with bent axle folder hole 3, and described bent axle folder hole 3 is cylindrical hole, and on described flange terminal pad 1, the position corresponding with bent axle folder hole 2 has track type through hole 4 No. one.Clamp body 2 leading flank right sides laterally have an expansion joint 5, and described expansion joint 5 is through bent axle folder hole 3 central axis, and expansion joint 5 left ends have a through hole 16 parallel with bent axle folder hole 3.Described clamp body 2 top left side have a tapped through hole 6, and described tapped through hole 6 is vertical with expansion joint 5 and through 5 right sides, expansion joint, also include and tapped through hole 6 match lock-screw 7 and nut 8.
The clamping degree of described bent axle folder hole 3 can be by the screwing and loosen and adjust of lock-screw 7 and nut 8, and compared to original fixture, of the present utility model to clamp mode simpler.
As shown in Figure 2, Figure 4 shows, described clamp body 2 leading flanks have three No. two track type through holes 9, described three No. two track type through holes 9 are triangularly arranged, the position of matching with three No. two track type through holes 9 on described flange terminal pad 1 respectively has a tapped blind hole 10, also include the alignment pin 11 matching with No. two track type through holes 9 and tapped blind hole 10, described clamp body 2 is fixedly connected with flange terminal pad 1 by alignment pin 11.New described three tapped blind holes 10 of the utility model are triangularly arranged, and its arrangement mode is identical with three No. two track type through hole 9 arrangement modes.
Different bent axles, the distance of the central axis of its trunnion and the central axis of rod journal is not identical, when adding man-hour to the rod journal of different bent axles, can realize by the relative position of adjusting clamp body 2 and flange terminal pad 1.Specifically by adjusting, No. two track type through holes 9 and the position of tapped blind hole 10 realize, and only tapped blind hole 10 need be adjusted to the diverse location of No. two track type through holes 9, then be fixed connection by alignment pin 11, just can adapt to the processing of different bent axles.
As shown in Figure 1, Figure 3, also include and clamp detent mechanism 12, the described detent mechanism 12 that clamps comprises base 13 and locating dowel 14, described base 13 is fixed on grinding machine table top, described locating dowel 14 is vertically fixed on base 13 tops, described in clamp detent mechanism 12 and match in clamp body 2 fronts and with clamp body 2.
