Abstract
The utility model relates to a sheet pressing device for a motor rotor. The sheet pressing device for the motor rotor comprises open washers, pressing plates and gaskets, wherein the middle parts of the pressing plates and the middle parts of the gaskets are respectively provided with a through hole; the rod part of a locking bolt is connected with a nut after passing through the open washers, the pressing plates and the gaskets in sequence; and the nut is a quadrilateral nut. Compared with the prior art, the sheet pressing device for the motor rotor has the beneficial effects that the rod part of the locking bolt is connected with the quadrilateral nut after passing through the open washers, the pressing plates and the gaskets in sequence, and the pressing plates are tightly compressed on a rotor coil through matching the locking bolt and the quadrilateral nut, and therefore, the coil is effectively prevented from loosening. The sheet pressing device for the motor rotor is simple in manufacturing, safe and reliable, can adapt to waste iron cores and is high in practicability and is good in market prospect.
Description
Technical field
The utility model belongs to technical field of motors, refers in particular to a kind of preforming device of rotor.
Background technology
The preforming device of existing rotor adopts lock screw directly pressing plate to be locked on the rotor core usually; or cooperate by clamping screw and hex nut pressing plate is locked on the rotor core; thereby reach the purpose of protection coil; avoid the loosening of coil; there is defective in its structural design; scheme by the direct fixation clip of lock screw needs special-purpose iron core; its processing is comparatively complicated; practical value is not high; be fixed the scheme of pressing plate by clamping screw and hex nut; occur easily between the sidewall of its hex nut and the rotor core skidding; and hex nut makes iron core produce distortion easily when installing; come off easily after using a period of time, cause rotor to be scrapped.
Summary of the invention
The purpose of this utility model is to provide a kind of making simple, safe and reliable, and can adapt to the preforming device of the rotor of old iron core.
For achieving the above object, the utility model provides following technical scheme: a kind of preforming device of rotor, comprise open washer, pressing plate and pad, pressing plate and pad middle part are equipped with through hole, and the bar section of a clamping screw is connected with a nut after sequentially passing open washer, pressing plate, pad.
Above-mentioned nut is tetragonal nut.
The utility model beneficial effect compared to existing technology is: the bar section of clamping screw of the present utility model is connected with a tetragonal nut after sequentially passing open washer, pressing plate, pad, by clamping screw and tetragonal nut cooperation pressing plate is pressed on the rotor coil, effectively avoided the loosening of coil, it makes simple, safe and reliable, and can adapt to old iron core, practicality is good, has preferably market prospects.
Description of drawings
Fig. 1 is the utility model and the schematic diagram that cooperates of rotor core.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of preforming device of rotor comprises open washer 3, pressing plate 5 and pad 2, and pressing plate 5 and pad 2 middle parts are equipped with through hole, and the bar section of a clamping screw 4 is connected with a nut 6 after sequentially passing open washer 3, pressing plate 5, pad 2.
Above-mentioned nut 6 is tetragonal nut.
Generator rotor core 1 is comprised of some chips, have a pair of symmetrical dovetail shaped breach at every chip, one core assembly sheet just forms two cross sections and is swallow-tailed coil groove 8, form the mounting groove 7 that cooperates with described nut 6 on the projection at coil groove 8 middle parts, the utility model can effectively be avoided the loose phenomenon of coil after motor uses longer a period of time, has reduced the noise of motor operation.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection range of the present utility model.
