Description
Technical field
The utility model relates to aviation pneumatic accessories maintenance technique field, relates in particular to a kind of screw thread profile shaft envelope puller.
Background technology
At present, in the maintenance of aviation annex, need to tear open the axle envelope of pulling out the different size size, take various mode according to axle envelope nip mostly when pulling out the axle envelope and tear open, very poor efficiency inconvenience when dismounting like this, and cause the damage of axle envelope easily.
The utility model content
The purpose of this utility model is to design a kind of novel screw thread profile shaft envelope puller, addresses the above problem.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of screw thread profile shaft envelope puller comprises connecting rod, the first adjusting axle sleeve, the second adjusting axle sleeve, first support sleeve, second support sleeve and split bush, and an end of described split bush is provided with the lining mouth, and the outer rim of described lining mouth is provided with a blockade hook; The lower end slip cap of described connecting rod is contained in the described split bush, the lower end of described connecting rod is provided with back taper type tapered end after passing described lining mouth, and the top slip cap of described connecting rod is contained in the described first adjusting axle sleeve slip and withstands described first downwards and regulate axle sleeve; The described first lower thread suit of regulating axle sleeve is connected described second and regulates outside the top of axle sleeve, and described second bottom of regulating axle sleeve connects described split bush; The described first support sleeve slip cap is contained in outside the described second adjusting axle sleeve and upwards withstands described second and regulate axle sleeve, and the described second top thread set of regulating axle sleeve is connected outside the bottom of described first support sleeve.
Also comprise hex nut, described connecting rod stretches out described first end of regulating axle sleeve and is provided with the external screw thread that matches with described hex nut, and described hex nut is threaded on the described external screw thread, and described hex nut withstands described first downwards and regulates axle sleeve.
Described second lower thread of regulating axle sleeve connects the top of described split bush.
The utility model relates to an a kind of device that needs to tear open the axle envelope in aviation pneumatic accessories maintenance, especially can conveniently use and seals according to tearing the axle that pulls out different sizes open.For being threaded, the regulating shaft inner room is for being threaded between support sleeve.Can the spreading split bush when connecting rod is promoted by jack-up, swivel bearing axle sleeve axle envelope can be removed.Changing split bush when the axle envelope of dismounting different size gets final product.
Connecting rod passes split bush in the utility model, inverted cone surface can make it to bind tight with axle by spreading axle sleeve step in tearing the process of pulling out open, between described support sleeve for being threaded, rotating first support sleeve can make it rotate in second support sleeve on the moving connecting rod of shipper pole to move, first regulates the fine-tuning connecting rod rising of axle sleeve displacement, moving on being somebody's turn to do is to be caused by screw thread rotation, can friction tight axle envelope be extracted with very little torque.Regulating axle sleeve can finely tune and make and move on the connecting rod.Different sizes can be made according to axle envelope size in the split bush lower end.
The beneficial effects of the utility model are as follows:
1, the utility model can be torn open under any tightness of axle envelope and pull out the axle envelope, improves the convenience of operation greatly, and simple in structure.
2, when the utility model is torn the axle envelope of pulling out different size dimensions open at needs, change split bush and get final product, quick and convenient.
3, the utility model has solved little axle envelope can not pull out the problem that an instrument is extracted and its boat material that do not damage easy and simple to handle with using always.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
A kind of screw thread profile shaft envelope puller as shown in Figure 1, comprise connecting rod 1, the first adjusting axle sleeve 2, the second adjusting axle sleeve 3, first support sleeve 4, second support sleeve 5, hex nut 6 and split bush 7, one end of described split bush 7 is provided with lining mouth 8, and the outer rim of described lining mouth 8 is provided with a blockade hook 9; The lower end slip cap of described connecting rod 1 is contained in the described split bush 7, the lower end of described connecting rod 1 is provided with back taper type tapered end 10 after passing described lining mouth 8, the top slip cap of described connecting rod 1 is contained in described first and regulates in axle sleeve 2 slips, described connecting rod 1 Shen goes out described first end of regulating axle sleeve 2 and is provided with the external screw thread that matches with described hex nut 6, described hex nut 6 is threaded on the described external screw thread, and described hex nut 6 withstands described first downwards and regulates axle sleeve 2; The described first lower thread suit of regulating axle sleeve 2 is connected described second and regulates outside the top of axle sleeve 3, and described second lower thread of regulating axle sleeve 3 connects described split bush 7; Described first support sleeve, 4 slip caps are contained in outside the described second adjusting axle sleeve 3 and upwards withstand described second and regulate axle sleeve 3, and the described second top thread set of regulating axle sleeve 3 is connected outside the bottom of described first support sleeve 4.
Move by screw thread pair between each assembly of the utility model.Pull out axle envelope 11 o'clock and regulate on the axle sleeve drivening rods 1 and move tearing open by rotating first support sleeve, 4 jack-up first and second, connecting rod 1 lower end is the back taper type tapered end 10 of inverted cone surface, move spreading split bush 7 on the conical surface, the axle blockade hook 9 of split bush 7 outer rims blocks to move on the axle envelope 11 can steadily extract axle envelope 11.Same rotation first is regulated axle sleeve 2 and can also be reached same purpose.
