Abstract
The utility model provides a device for taking a sleeve out of a blind hole skillfully, which comprises a hollow outer sleeve, an inner sleeve, a bolt and a lining, wherein the hollow outer sleeve and the inner sleeve are accommodated in a bearing outer sleeve, the bolt penetrates through the inner sleeve, and the lining is arranged above the outer sleeve to press the inner sleeve into the outer sleeve; wherein the diameter of the outer sleeve increases gradually along the direction toward the bottom of the blind hole, and the maximum outer diameter of the outer sleeve is equal to the minimum inner diameter of the bearing outer sleeve. Due to the device of the utility model, a shaft sleeve can be taken out of the blind hole easily.
Description
Technical field
The utility model relates to a kind of machine tools, particularly a kind of device that steals cover in the blind hole.
Background technology
Run into such a case in machine maintenance sometimes: damage of bearings and falling apart, bearing outside is set in the blind hole and can't takes out.The author has designed one for it and has extracted the cover instrument, is easy to just the bearing outside that is pressing in the blind hole got.
The utility model content
Technical problem to be solved in the utility model provides a kind of device that steals cover in the blind hole, and it can take out interior cover very like a cork in blind hole.
For achieving the above object, the utility model provides a kind of device that steals cover in the blind hole, comprise be placed in the bearing outside and the overcoat and the interior cover of hollow, run through in the bolt of cover, and place the overcoat top interior cover is pressed into the lining in the overcoat, wherein, the diameter of overcoat is along with increasing gradually towards blind hole bottom, and the external diameter of overcoat maximum equates with the minimum diameter of bearing outside.
As most preferred embodiment of the present utility model, the inner cone of described overcoat is 1: 5 with the ratio of the outer cone of interior cover.
Compared with prior art, the device that the utility model steals cover in the blind hole has the following advantages at least: the overcoat diameter of the utility model device is gradual change, and along with increasing gradually towards the blind hole bottom, therefore, when mounted, with bolt and lining interior cover slowly is pressed into overcoat, during dismounting, takes down lining, again screw in bolt, make bolt head withstand blind hole bottom, precession bolt again, described bearing outside gradually goes out immediately.
Description of drawings
Fig. 1 is device that the utility model steals cover in the blind hole cutaway view when being installed in the blind hole;
Fig. 2 is device that the utility model steals cover in the blind hole another cutaway view when being installed in the blind hole.
Number in the figure is described as follows:
1 is blind hole, and 2 is bearing outside, and 3 is overcoat, and 4 is interior cover, and 5 is bolt, and 6 is lining.
The specific embodiment
Specifically introduce the specific embodiment that the utility model steals the device that overlaps in the blind hole below in conjunction with accompanying drawing:
See also Fig. 1 to shown in Figure 2, the device that the utility model steals cover in the blind hole comprises overcoat 3 and the interior cover 4 that is placed in the bearing outside 2, the bolt 5 that runs through interior cover 4, and the lining 6 that places overcoat 3 tops.
The specification of described overcoat 3, interior cover 4 and bolt 5 is chosen according to the model and the specification of bearing, and the effective length of described bolt 5 determines that according to the degree of depth of blind hole 1 bolt is shorter if blind hole 1 is crossed dark, then can be encased inside suitable protector in the bottom of blind hole 1 in advance.
Described overcoat 3 and interior cover 4 are hollow structure, and the diameter of overcoat 3 is gradual change in the blind hole depth direction, specifically, the bottom of past more blind hole, the diameter of overcoat 3 is big more; The inner cone of described overcoat 3 is 1: 5 with the ratio of the outer cone of interior cover 4, the external diameter of the maximum of overcoat 3 is a principle with the minimum diameter by bearing outside 2 just, the shape optical axis of its outer round surface holds the inner surface of overcoat and decides, should be with the handsaw opening so that distending after processing.
During installation, at first interior cover 4 is put into overcoat 3 from the less end of overcoat 3 diameters, interior cover 4 and the overcoat 3 that to combine are then put into axle sleeve overcoat 2 in the lump, follow again, with bolt 5 and lining 6 interior cover 4 slowly is pressed into overcoat 3, makes overcoat 3 distendings and serve as a contrast the inner surface that mandrel holds overcoat 2 gradually; During taking-up, at first take down lining 6, screw in bolt 5 again, make bolt 5 crowns live blind hole 1 bottom, the precession bolt 5 again, and then bearing outside 2 gradually goes out immediately.
The above only is a kind of embodiment of the present utility model, it or not whole or unique embodiment, the conversion of any equivalence that those of ordinary skills take technical solutions of the utility model by reading the utility model specification is claim of the present utility model and contains.
Claims (2)
1. one kind steals the device that overlaps in the blind hole, it is characterized in that: comprise being placed in the bearing outside (2) and the overcoat (3) and the interior cover (4) of hollow, running through the bolt (5) of interior cover (4), and place overcoat (3) top interior cover (4) is pressed into the lining (6) in the overcoat (3), wherein, the diameter of overcoat (3) is along with increasing gradually towards blind hole bottom, and the maximum external diameter of overcoat (3) equates with the minimum diameter of bearing outside (2).
2. the device that steals cover in the blind hole as claimed in claim 1, it is characterized in that: the ratio of the outer cone of the inner cone of described overcoat (3) and interior cover (4) is 1: 5.
