Encoder axiality device rectifies

Technical Field

The utility model relates to a deviation-correcting encoder axiality device.

Background

In order to accurately measure the number of turns of rotation and the speed of the compression roller used for producing the strip cold rolling mill, the encoder is usually installed on the motor of the cold rolling mill, but the rotating shaft of the encoder in the prior art is generally rigidly connected with the motor shaft, so that when the rotating shaft of the encoder is not coaxial with the motor shaft, the rotating shaft of the encoder is not synchronous with the rotation of the motor shaft, the rigid connection is easily damaged and broken, and the encoder is damaged.

SUMMERY OF THE UTILITY MODEL

The utility model discloses improve above-mentioned problem, promptly the to-be-solved technical problem of the utility model is to provide a deviation correcting encoder axiality device, simple structure and convenient to use avoid encoder or motor part to damage.

The utility model discloses a constitute like this, it includes by a left side to the fixed disk that sets gradually, fixed aligning frame and motor, the fixed disk mid-mounting has the encoder, and the pivot of encoder and the coaxial setting of axle of motor are provided with between the two and connect the soft cover.

Furthermore, one side that fixed aligning frame is close to the casing of motor is equipped with the extension board, is equipped with fixed notch on the casing of motor, and the mounting wears to establish the extension board in proper order and fixes with fixed notch.

Furthermore, protective sleeves are arranged outside the encoder and the fixed aligning frame.

Further, the protective sheath surface is equipped with the mesh, and protective sheath one end is fixed with the nut cover, and the protective sheath other end is equipped with fixing bolt.

Compared with the prior art, the utility model discloses following beneficial effect has: this device reasonable in design, simple structure, through the fixed position of the fixed aligning bracket of adjustment, guarantees the axiality of the axle of encoder and motor, connects the mantle simultaneously and plays the effect of remedying the axiality not enough, when there is some deviations in the pivot of encoder and the axle axiality of motor, can avoid taking place the damage when the pivot of encoder rotates with the axle synchronization of motor.

Drawings

FIG. 1 is a schematic structural diagram of an embodiment of the present invention;

fig. 2 is a schematic view showing the deployment of the protective sheath according to the embodiment of the present invention.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

The embodiment is as follows: as shown in fig. 1-2, in this embodiment, a device for correcting the coaxiality of an encoder is provided, which includes an encoder 1 and a motor 2 coaxially disposed, and a connection soft sleeve 3 is disposed and fixed between a rotating shaft 11 of the encoder and a shaft 21 of the motor.

The connecting soft sleeve plays a role in connecting the rotating shaft of the encoder and the shaft of the motor, and transmits the rotating speed power of the shaft of the motor to the rotating shaft of the encoder to drive the rotating shaft of the encoder to rotate; meanwhile, when the rotating shaft of the encoder and the shaft coaxiality of the motor have some deviations, the soft sleeve is connected to play a role in compensating for the insufficient coaxiality, the rotating shaft of the encoder and the shaft of the motor can be prevented from being damaged during synchronous rotation, and the soft sleeve is connected equivalently to be connected in a deviation rectifying mode.

The middle part of the connecting soft sleeve is provided with a fixing hole position for the penetration of the rotating shaft 11 of the encoder and the shaft 21 of the motor.

The encoder is arranged in the middle of the fixed disc 4, a fixed aligning frame 5 is arranged between the fixed disc and the shell of the motor, an extension plate 6 is arranged on one side, close to the shell of the motor, of the fixed aligning frame, and a fixing piece 7 is arranged on one side, close to the shell of the motor, of the fixed aligning frame and used for being matched with a fixed notch formed in the shell of the motor; the fixing piece penetrates through the extension plate and the fixing notch in sequence to be fixed.

The fixed position of unblock mounting through the fixed aligning frame of adjustment guarantees the axiality of encoder and motor's axle, and reuse mounting is fixed the aligning frame again.

The fixing member may be a bolt or a screw-nut assembly.

Foretell fixed aligning frame can be provided with a plurality ofly, has the dead slot between the adjacent fixed aligning frame, conveniently overhauls and changes the encoder, connect soft cover or motor lateral part.

In this embodiment, the encoder and the fixed core frame are externally provided with a protective sleeve 8.

The surface of the protective sleeve is provided with meshes 81, a nut sleeve is fixed at one end of the protective sleeve, and a fixing bolt 83 is arranged at the other end of the protective sleeve; the head diameter of the bolt is larger than the diameter of the mesh.

The protective sleeve can also fix other modes into a cylindrical shape, which is not described in detail herein.

The protective sleeve is wound on the encoder and the outer part of the fixed aligning frame to form a cylinder, the hollow groove is shielded, and then the two ends of the protective sleeve are fixed through the fixing bolts.

Any technical solution disclosed in the present invention is, unless otherwise stated, disclosed a numerical range if it is disclosed, and the disclosed numerical range is a preferred numerical range, and any person skilled in the art should understand that: the preferred ranges are merely those values which are obvious or representative of the technical effect which can be achieved. Because numerical value is more, can't be exhaustive, so the utility model discloses just disclose some numerical values with the illustration the technical scheme of the utility model to, the numerical value that the aforesaid was enumerated should not constitute right the utility model discloses create the restriction of protection scope.

Meanwhile, if the utility model discloses a disclose or related to mutually fixed connection's spare part or structure, then, except otherwise stated, fixed connection can be understood as: a detachable fixed connection (for example using screws or screw connections) is also understood as: non-detachable fixed connections (e.g. riveting, welding) can, of course, also be replaced by one-piece structures (e.g. manufactured in one piece using a casting process) (unless it is obvious that one-piece processes cannot be used).

If the terms "first," "second," etc. are used herein to define parts, those skilled in the art will recognize that: the terms "first" and "second" are used merely to distinguish one element from another in a descriptive sense and are not intended to have a special meaning unless otherwise stated.

In addition, the terms used in any aspect of the present disclosure as described above to indicate positional relationships or shapes include similar, analogous, or approximate states or shapes unless otherwise stated.

The utility model provides an arbitrary part both can be assembled by a plurality of solitary component parts and form, also can be the solitary part that the integrated into one piece technology was made.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same; although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that: modifications can still be made to the embodiments of the invention or equivalents may be substituted for some of the features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
