Embodiment

Disclosed all features in this instructions, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.

Disclosed arbitrary feature in this instructions (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of bent axle finished product detection support, comprise base 1, stake body 2, V-block 4 and be fixed on the tape spool roller 5 on 4 liang of tops of V-block, stake body 2 is the relative setting that slides up and down with V-block 4, be relative horizontal slip setting between base 1 and the stake body 2, above-described is a sliding support.The corresponding bolt connecting hole that is provided with needs to use fixed support sometimes between base 1 and stake body 2, and a pin 11 that only needs to be complementary is put into connecting holes, has been exactly fixed crankshaft finished product detection support.

V-block 4 lower surfaces are the inclined-plane, have chute on the inclined-plane, be set with voussoir 3 in V-block 4 lower ends, the upper surface of this voussoir 3 for the inclined-plane that is complementary, V-block 4 lower surfaces, chute on the inclined-plane with V-block 4 boss that is complementary is arranged on the inclined-plane of voussoir 3, be provided with the chute that can on stake body 2 surface levels, slide below the voussoir 3, on the surface level in the stake body 2 boss that is complementary with voussoir 3 below chutes is arranged, vertical both sides correspondence in stake body 2 is provided with chute, be provided with the boss that is complementary with stake body 2 upper hopper chutes in the both sides of V-block 4, the chute homogeneous phase that above-described boss and its are complementary separately is slidingly connected, be fixed with one movably in stake body 2 sides and regulate handle 10, regulate handle 10 and fuse by bolt 9 and voussoir 3.

Base 1 is provided with several stopper slots, and roller 6 is arranged in the roller stopper slot 13 that is complementary with it, and the slip locating part 8 that is fixed on the stake body is arranged in the sliding part stopper slot 12 that is complementary with it.

Also be provided with banking stop 7 between base 1 and the stake body 2, this banking stop 7 is provided with roller spacing hole 14 and sliding part spacing hole 15, spacing hole is all corresponding on stake body 2 stopper slots, each roller 6 equal correspondence is positioned over a roller spacing hole that is complementary with it 14 times, each slip locating part 8 equal correspondence is positioned over a sliding part spacing hole that is complementary with it 15 times, and roller 6 all can relative slip in each self-corresponding spacing hole with it with slip locating part 8.

Fig. 8 is the structural representation of bent axle, wherein a represent to support herein be fixed support; Wherein b represent to support herein be sliding support.

For sliding support and fixed support, twist and regulate 9 rotations of handle 10 drive bolts, the screw thread of bolt 9 drives voussoir 3 and moves horizontally in the bottom surface of V-block 4, owing to moving horizontally of voussoir 3, just promote V-block 4 and move up and down, thereby can adjust moving up and down of V-block very easily.

For sliding support, because the effect of No. 6, roller and slip locating part 8, sliding support can move horizontally at certain distance.

When checking the bent axle precision, use two fixed supports and a plurality of sliding support, the usage quantity of sliding support is decided on the bent axle situation, the bent axle of N king journal uses N-2 sliding support, simultaneously, set up a clock gauge with the magnetic force gauge stand on each sliding support, gauge outfit withstands on the bolt 9.

Like this, when rotary crankshaft, because the decentraction of each king journal of bent axle, the rotation of bent axle is under the effect of decentraction, sliding support will produce and move horizontally, its displacement can show on the clock gauge that withstands on bolt 9, and its video data is exactly the malalignment data of this king journal of bent axle to two fixed support king journal concentric lines.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
