Abstract
The utility model relates to a motor rotor bearing pulling and unloading device which is used for dismounting a bearing from a motor rotor and belongs to the motor tool technology field. The motor rotor bearing pulling and unloading device includes a crossbeam, an adjusting screw rod, a crossbeam slide groove, a first movable clamp plate, a first movable clamp jaw, first connecting bolts, a second movable clamp plate, a second movable clamp jaw, and second connecting bolts. The lower end of the crossbeam is provided with the crossbeam slide groove. The crossbeam slide groove is slidingly provided with the first movable clamp plate and the second movable clamp plate. The first movable clamp plate is connected with the first movable clamp jaw via the first connecting bolts. The second movable clamp plate is connected with the second movable clamp jaw via the second connecting bolts. The adjusting screw rod is threadedly connected with a through hole in the center of the crossbeam. The motor rotor bearing pulling and unloading device is simple, compact and reasonable in structure, and is simple and safe in operation, so the dismounting speed is improved, the labor intensity of a worker is reduced, and the dismounting efficiency is improved.
Description
Technical field
The utility model relates to a kind of rotor bearing drawing and disassembling device, specifically is used for rotor dismounting bearing, belongs to motor frock technical field.
Background technology
When rotor need to be dismantled bearing at present, usually adopt traditional Three-claw pull-horse instrument to tear need open bearing and remove.When running into the rotor of large-size specification, dismantlement work just is difficult to carry out.Need the extracting tool of dimension to operate, bring difficulty to dismantlement work, and safe operation process is not high; Simultaneously, the labour intensity of dismantlement work is higher, has had influence on the efficient of dismantlement work.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of rotor bearing drawing and disassembling device is provided, and has improved dismounting speed, has reduced operator's labour intensity, has improved the efficient of dismantlement work.
The technical scheme that provides according to the utility model, the rotor bearing drawing and disassembling device comprises crossbeam, regulates screw mandrel, crosstic shoe, the first ambulatory splint, the first movable jaw, the first connecting bolt, the second ambulatory splint, the second movable jaw and the second connecting bolt, it is characterized in that: the crossbeam lower end is provided with crosstic shoe, and the first ambulatory splint and the second ambulatory splint are slidingly installed on the crosstic shoe.Connect the first movable jaw by the first connecting bolt on described the first ambulatory splint.Connect the second movable jaw by the second connecting bolt on described the second ambulatory splint.Regulate the through hole that screw mandrel is threaded connection the crossbeam center, regulate screw mandrel between the first movable jaw and the second movable jaw.
Described adjusting screw mandrel lower end is nose cone.
Described crossbeam is I shape.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Easy to operate, safety; Improved dismounting speed; Reduced operator's labour intensity; Improved the efficient of dismantlement work.
Description of drawings
Fig. 1,2 is the utility model structural representation.
Description of reference numerals: 1-crossbeam, 2-regulate screw mandrel, 3-crosstic shoe, 4-the first ambulatory splint, 5-the first movable jaw, 6-the first connecting bolt, 7-the second ambulatory splint, 8-the second movable jaw, 9-the second connecting bolt.
Embodiment
Following the utility model is further described in connection with the embodiment in the accompanying drawing:
Shown in Fig. 1 ~ 2, the utility model mainly comprises crossbeam 1, regulates screw mandrel 2, crosstic shoe 3, the first ambulatory splint 4, the first movable jaw 5, the first connecting bolt 6, the second ambulatory splint 7, the second movable jaw 8 and the second connecting bolt 9.
Crossbeam 1 is I shape, and crossbeam 1 lower end is provided with crosstic shoe 3.The first ambulatory splint 4 and the second ambulatory splint 7 are slidingly installed on the crosstic shoe 3.Connect the first movable jaw 5 by the first connecting bolt 6 on described the first ambulatory splint 4.Connect the second movable jaw 8 by the second connecting bolt 9 on described the second ambulatory splint 7.
Regulate the through hole that screw mandrel 2 is threaded connection crossbeam 1 center.Described adjusting screw mandrel 2 is between the first movable jaw 5 and the second movable jaw 8.
Described adjusting screw mandrel 2 lower ends are nose cone.
The utility model hooks the first movable jaw 5 and the second movable jaw 8 distributions by adjusting the first ambulatory splint 4 and the second ambulatory splint 7 outer rim of the bearing of tearing open when work.Rotate and regulate screw mandrel 2, the nose cone of its lower end is entered in the interior centre bore of bearing.Regulate the position of the first ambulatory splint 4 and the second ambulatory splint 7, so that the first movable jaw 5 is vertical with crossbeam 1 with the second movable jaw 8.Rotate by special-purpose wrench and to regulate screw mandrel 2, so that regulate screw mandrel 2 bearing is pulled down.
The utility model can better guarantee its fail safe in whole rotor bearing disassembling section process, thereby satisfies the quality requirement of its bearing removal.So that the more quick and easy and safety of rotor bearing dismounting is hanged down the labour intensity in the dismounting bearing process greatly, improved the efficient of dismantlement work.
