Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, in embodiment shown in Fig. 5, a kind of slender axles coalignment, comprise the push-down head 1 be connected with forcing press, two support roller vehicle 2 in advance, two positioning supporting frames 3, described pre-support roller vehicle comprises support base plate 4, support upper plate 5, some movable pulleys 6, described support upper plate is provided with roller support 7, described roller support is provided with two roller shafts 8 parallel to each other, described roller shaft is provided with work mounting s roller 9, described support base plate is provided with two shaft seats 10, a rotating shaft 11 is threaded with two shaft seats, described rotating shaft is provided with at least one eccentric wheel 12, described eccentric wheel contact support upper plate bottom surface, described support base plate is provided with some guide upright posts 13, described guide upright post is through support upper plate, described positioning supporting frame comprises lower triangular basis 14, a upper support group 15, described lower triangular basis is provided with a long step inclined plane 16, described upper support group is provided with a short step inclined plane 17 can fitted with long step inclined plane, described upper support group is provided with the V-shaped groove 18 for support elongated axle.Its shaft, by screw thread self-locking, also can be movable rotation-shaft, be positioned by the structure such as outer bolt, screw.
Described rotating shaft one end is stretched out outside one piece of shaft seat, and this external part of rotating shaft is provided with rotating operation head 19.Utilize rotating operation head that rotating shaft can be driven easily to rotate thus push support upper plate to move up and down, instrument also can be utilized to come, to rotating operation head force, to make rotation more laborsaving and convenient.
Described eccentric wheel number is two, and described eccentric eccentric throw is 10 millimeters.That is the range difference that moves up and down of support upper plate is 10 millimeters, thus the adjustable-height being corrected axle is also 10 millimeters.
The length of described long step inclined plane is greater than 1.5 times of short step inclined plane length, and described lower triangular basis width is greater than 1.2 times of support sound stage width degree.The length of long step inclined plane is comparatively large, can provide and more regulate leeway, and lower triangular basis width is comparatively large, is beneficial to stable support.
The bottom land of described V-shaped groove is provided with rectangle strengthening groove 20, and the length direction of described rectangle strengthening groove is parallel with the length direction of V-shaped groove.Elongated pedestal on V-shaped groove after, bottom land place receives the larger stress towards both sides, by arrange rectangle strengthening groove, dispersion concentrate stress, effectively can play strengthening effect.
During work, first slender axles (workpiece) are placed in two and support V-shaped groove on roller vehicle in advance, rotating shaft, the work mounting s roller supporting roller vehicle is in advance made to be in a high position, axle is risen 10 millimeters, now, i.e. available hand slowly turning of work piece, and beated by the circle in dial gauge measuring workpieces somewhere.By with hand propelled roller vehicle and on workpiece, the circle of workpiece diverse location is beated and takes multiple measurements, the flexibility of this section (namely between second wheel car) workpiece can be determined.
Then push-down head workpiece is utilized to carry out the alignment that exerts a force: according to the bending situation of this section of workpiece, determine the point of application on axle, and by move axially two support in advance roller vehicles and on workpiece, make push-down head just to the determined point of application (the height point of workpiece is upward).Regulate the position of positioning supporting frame again, now positioning supporting frame height should be adjusted to and can just to hold below workpiece and as far as possible near supporting roller vehicle in advance.It is then the diverse location upper support group being seated in the long step inclined plane of lower triangular basis that the height of positioning supporting frame regulates, and realizes, just can contact with V-type groove, frame lives slender axles and be advisable.
Rotating shaft makes two to support roller vehicle in advance and is in low order position again, and now workpiece is supported by upper support group completely.Starting pressure machine, push-down head to exert a force alignment to workpiece, and the weight of the stressed and workpiece now on workpiece is all born by positioning supporting frame, and the pre-roller vehicle that supports does not stress.The size of forcing press force is directly proportional to workpiece bows degree, and need keep certain force time.
After the alignment of workpiece force, again need measure flexibility, rotating shaft makes two to support roller vehicle in advance and is in upper level position, and workpiece is departed from V-type groove after jack-up, now again can measure the flexibility after force alignment.
Repeat said process, till workpiece bows degree meets the requirements.
