Abstract
The utility model discloses a fixing device for middle support of a long shaft lead screw, which comprises a support sleeve (5) with one end provided with a shaft shoulder (8) and an excircle of the other end provided with threads. An inner hole of the support sleeve with one end with threads is a taper hole which is internally equipped with a taper expanding sleeve (3), and the outer end of the taper expanding sleeve is provided with a locknut (2) which can axially support against the taper expanding sleeve (3) while being screwed with the support sleeve (5). The fixing device is used to install a supporting bearing in the middle of the slender shaft by means of the transitional expanding sleeve, with advantages of simple structure, convenient installation and reliable support and fixation.
Description
Technical field
The utility model relates to a kind of slender axles screw mandrel intermediate support positioning device, and this device can be applied to shield the intermediate support location of every machine left and right sides screw mandrel, convenient and swift installation.
Background technique
In order to satisfy designing requirement, often the screw mandrel of left and right sides spiral is made a kind of monolithic construction, this screw mandrel is slender axles.For the installation of slender axles, the position must increase the supporting rigid bearing therebetween, but because the operational characteristic of screw mandrel manufacturing processing can not be processed into garden cylinder outside the boss in the intermediate portion of screw axis, satisfies bearings mounted requirement.Thereby the slender axles middle part is supported when being installation and is often run into a difficult problem, and industry is being sought a kind of simple and convenient support device always, to improve the rigidity of slender axles.
Summary of the invention
The utility model is in order to solve the technical problem that existing slender axles middle part spring bearing can not be installed, to propose a kind of major axis screw mandrel intermediate support fixing device simple in structure, easy for installation.
For solving the problems of the technologies described above, the technical solution of the utility model is a kind of major axis screw mandrel intermediate support fixing device of structure, it comprises that an end is provided with the supporting sleeve that the outer garden of the shaft shoulder the other end is provided with screw thread, supporting sleeve is threaded the endoporus at an end place and is arranged to cone shape hole, when an equipped taper ringfeder in this cone shape hole, the outer end of taper ringfeder are provided with and screw with described supporting sleeve at the locking nut that axially can hold out against the taper ringfeder.
Wherein, can also be provided with locking Cock screw on the outer garden wall body of described locking nut.
The utility model has adopted a kind of mode of transition ringfeder to be used for slender axles middle part mounting support bearing.Compared with the prior art, it is simple in structure, easy for installation, and support fixation is firm.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is described in detail, wherein:
Fig. 1 is the sectional view of the utility model preferred embodiment;
Fig. 2 is the application schematic representation of the utility model preferred embodiment.
Embodiment
Fig. 1 shows the basic structure of the utility model preferred embodiment, described major axis screw mandrel intermediate support fixing device, and it comprises a supporting sleeve 5, the left end of this supporting sleeve is provided with the shaft shoulder 8, the outer garden of right-hand member is provided with screw thread.The endoporus that is threaded the supporting sleeve 5 of an end is arranged to cone shape hole, an equipped taper ringfeder 3 in this cone shape hole.The cylindrical bore of supporting sleeve 5 and taper ringfeder 3 cooperates with the external diameter of the major axis screw mandrel that is supported.Be provided with in the outer end of taper ringfeder 3 when screwing with supporting sleeve 5 at the locking nut 2 that axially can hold out against taper ringfeder 3, the outer garden wall body of locking nut is provided with locking Cock screw 4.
As shown in Figure 2, during installation, at first supporting sleeve 5, taper ringfeder 3 are enclosed within the neutral position of major axis screw mandrel 1, again locking nut 2 are loaded onto and screwed left.For anti-locking nut becomes flexible the Cock screw 4 of screwing on.When locking nut screws, promote the taper ringfeder and axially move to left, material be the taper ringfeder of spring steel by tensioner, make supporting sleeve 5 be fastened on the major axis screw mandrel 1 outer garden face, played fixation.After supporting sleeve is fixed, just bearing 7 and bearing support 6 can be installed in supporting sleeve 5 and have on the shaft shoulder 8 one ends, so the centre of major axis screw mandrel 1 has also just obtained supporting effectively.
The utility model adopts the mode of transition ringfeder to be used for slender axles middle part mounting support bearing.Simple in structure, easy for installation, support fixation is firm.
Claims (3)
1, a kind of major axis screw mandrel intermediate support fixing device, it is characterized in that, comprise that an end is provided with the supporting sleeve (5) that the shaft shoulder (8) the other end cylindrical is provided with screw thread, the endoporus that is threaded the supporting sleeve of an end is arranged to cone shape hole, an equipped taper ringfeder (3) in this cone shape hole, the outer end of this taper ringfeder is provided with described supporting sleeve (5) axially can hold out against the locking nut (2) of taper ringfeder (3) when screwing.
2, major axis screw mandrel intermediate support fixing device as claimed in claim 1 is characterized in that the cylindrical wall body of described locking nut (2) is provided with locking Cock screw (4).
