Abstract
The utility model relates to extracting tool, particularly a kind ofly conveniently the one that the parts such as bearing, gear or belt wheel and axle are separated can be drawn horse.Form primarily of left plate combination, boosting mechanism, right plate combination, lower screw mandrel I and lower screw mandrel II; Left plate combination is identical with right plate combining structure, forms primarily of side plate, top nut, lower nut, upper gasket and lower gasket.Boosting mechanism is formed primarily of afterburning screw mandrel, afterburning nut, polished rod and upper screw rod.Side plate has polished rod hole, upper hole and two symmetrical lower opening.Afterburning screw mandrel and afterburning nut screw connection.Polished rod is fixedly connected with afterburning nut, and upper screw rod is fixedly connected with afterburning nut.Polished rod is parallel with upper screw rod.Polished rod coordinates with polished rod hole and can move freely.Top nut coordinates with upper screw rod, and the outside cylinder of top nut coordinates with upper hole and can freely rotate.Lower nut coordinates with lower screw mandrel I, lower screw mandrel II, and the outside cylinder of lower nut coordinates with lower opening and can freely rotate.This one draws that horse is rational in infrastructure, easy to adjust, operation is reliable.
Description
Technical field
The utility model relates to extracting tool, particularly a kind ofly conveniently the one that the parts such as bearing, gear or belt wheel and axle are separated can be drawn horse.
Background technology
In Product Assembly or maintenance process, often need part such as dismounting bearing, gear or belt wheel etc., but general draw horse in use because its two or three pawls are that movable being thus easy to skids off, make troubles to dismantlement work.
Utility model content
In order to address this problem, the utility model provides one to draw horse, can the parts such as bearing, gear or belt wheel and axle be separated by convenience and high-efficiency.
The technical scheme that the utility model adopts is:
Described one draws horse to form primarily of left plate combination, boosting mechanism, right plate combination, lower screw mandrel I and lower screw mandrel II.Described lower screw mandrel I is identical with described lower screw mandrel II structure.Described left plate combination is identical with described right plate combining structure, forms primarily of side plate, top nut, lower nut, upper gasket and lower gasket.Described boosting mechanism is formed primarily of afterburning screw mandrel, afterburning nut, polished rod and upper screw rod.Described side plate has polished rod hole, upper hole and two symmetrical lower opening.Described afterburning screw mandrel and described afterburning nut screw connection.Described polished rod is fixedly connected with described afterburning nut, and described upper screw rod is fixedly connected with described afterburning nut.Described polished rod is parallel with described upper screw rod.Described polished rod coordinates with described polished rod hole and can move freely.Described top nut coordinates with described upper screw rod, and the outside cylinder of described top nut coordinates with described upper hole and can freely rotate.Described lower nut coordinates with described lower screw mandrel I, described lower screw mandrel II, and the outside cylinder of described lower nut coordinates with described lower opening and can freely rotate.Get a described side plate, the outside cylinder of described top nut is inserted described upper hole, then loads onto described upper gasket and then rivet.The outside cylinder of two described lower nuts is inserted respectively two described lower opening, then respectively load onto a described lower gasket and then rivet, so just form the combination of described left plate.In like manner form the combination of described right plate.Then described left plate combination, the combination of described right plate are carried out being threaded with described boosting mechanism.
The beneficial effects of the utility model are:
Described one draws that horse is rational in infrastructure, easy to adjust, operation is reliable.
Accompanying drawing explanation
Further illustrate below in conjunction with figure of the present utility model:
Fig. 1 is structural representation of the present utility model.
Fig. 2, Fig. 3 are the structural representations of the combination of described left plate, the combination of described right plate.

In figure, 1. left plate combination, 2. boosting mechanism, 3. right plate combination, 4. descends screw mandrel I, 5. descends screw mandrel II, 6. side plate, 7. top nut, 8. lower nut, 9. upper gasket, 10. lower gasket, 11. afterburning screw mandrels, 12. afterburning nuts, 13. polished rods, 14. upper screw rods, 15. polished rod holes, on 16. hole, 17. lower opening.
Detailed description of the invention
Described one draws horse to combine (1), described boosting mechanism (2), described right plate combination (3), described lower screw mandrel I (4) and described lower screw mandrel II (5) formation primarily of described left plate.Described lower screw mandrel I (4) is identical with described lower screw mandrel II (5) structure.It is identical that described left plate combination (1) and described right plate combine (3) structure, forms primarily of described side plate (6), described top nut (7), two described lower nuts (8), described upper gasket (9) and two described lower gaskets (10).Described boosting mechanism (2) is formed primarily of described afterburning screw mandrel (11), described afterburning nut (12), described polished rod (13) and described upper screw rod (14).Described side plate (6) has described polished rod hole (15), described upper hole (16) and two symmetrical described lower opening (17).Described afterburning screw mandrel (11) coordinates with described afterburning nut (12).Described polished rod (13) is fixedly connected with described afterburning nut (12), and described upper screw rod (14) is fixedly connected with described afterburning nut (12).Described polished rod (13) is parallel with described upper screw rod (14).Described polished rod (13) coordinates with described polished rod hole (15) and can move freely.Described top nut (7) coordinates with described upper screw rod (14), and the outside cylinder of described top nut (7) coordinates with described upper hole (16) and can freely rotate.Described lower nut (8) coordinates with described lower screw mandrel I (4), described lower screw mandrel II (5), and the outside cylinder of described lower nut (8) coordinates with described lower opening (17) and can freely rotate.Get a described side plate (6), the outside cylinder of described top nut (7) is inserted described upper hole (16), then loads onto described upper gasket (9) and then rivet.The outside cylinder of two described lower nuts (8) is inserted respectively two described lower opening (17), then respectively load onto a described lower gasket (10) and then rivet, so just form described left plate combination (1).In like manner form described right plate combination (3).Then described left plate combination (1), described right plate combination (3) are carried out being threaded with described boosting mechanism (2).
During use, alternately top nut (7) and two described lower nuts (8) described in turn, described left plate is made to combine (1), distance between described right plate combination (3) is suitable, the lower hook of two described side plates (6) is made just to hook the bearing needing drawing, the part such as gear or belt wheel, afterburning screw mandrel (11) described in turn, the tip of described afterburning screw mandrel (11) is withstood bearing is housed, the centre bore of the axle of the part such as gear or belt wheel, slowly evenly described in turn, afterburning screw mandrel (11) just can by bearing in continuation, the part such as gear or belt wheel slowly pulls out.
