Abstract
The utility model discloses a balancing clamp used for a rotor core. A frustum in the shape of a circular truncated cone is arranged on the outer periphery of the central part of a rotary shaft coaxially and fixedly. A conical sleeve is arranged sleeving the frustum. The inner hole of the conical sleeve is in the shape of a circular truncated cone, matching with the frustum. The outer periphery of the conical sleeve matches with an inner hole of the rotor core. The conical sleeve is provided with at least two open grooves axially. The length of each open groove is 3/4 to 4/5 of the height of the conical sleeve. By adopting the balancing clamp provided by the utility model, the rotor core can be installed on the rotary shaft stably and closely, so that precision of detection results can be guaranteed.
Description
Technical field:
The utility model relates to a kind of rotor core balancing fixture.
Background technology:
The balancing fixture of rotor core is the degree of balance for measure rotor core on equilibristat, ensures the quality of rotor, and after being assemblied on magnetic drive pump, ensures the magnetic drive effect of pump.In prior art, with screwed fixture, rotor core is fixed on axle always, tighten and fix rotor core with the threaded nut of car, the weak point of this fixture be rotor core mating surface will with axle on mating surface reach very high accuracy and could realize and playing a role measuring in its degree of balance, so likely greatly reduce the result of its mensuration.
Summary of the invention:
For overcoming the defect of prior art, the purpose of this utility model is to provide a kind of rotor core balancing fixture, thereby rotor core firmly, closely can be assemblied in to the accuracy that ensures testing result in rotating shaft.
The utility model technical solution problem adopts following technical scheme:
A kind of rotor core balancing fixture, coaxially be installed with the frustum of truncated cone-shaped in the periphery at rotating shaft middle part, setting is socketed in the tapered sleeve of described frustum outside, the endoporus of described tapered sleeve is the truncated cone-shaped of mating with described frustum, the outer peripheral face of described tapered sleeve mates with the endoporus of described rotor core, described tapered sleeve body offers at least twice open slot vertically, and the length of described open slot is 3/4-4/5 of tapered sleeve height.
The number Wei2-8 road of described open slot, distributes along the circumferencial direction of described tapered sleeve etc. point.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The utility model is by arranging frustum in rotating shaft outer, coaxial, on frustum, be socketed a tapered sleeve, rotor core is socketed on tapered sleeve, on tapered sleeve, axially offer multiple open slots along it, like this, frustum in rotating shaft is assemblied in the endoporus of tapered sleeve as same chock, in the time that the endoporus of the more past tapered sleeve of large end of the frustum of rotating shaft gos deep into, tapered sleeve is more inflated, open slot provides surplus for the expansion of tapered sleeve external diameter, and tapered sleeve external diameter expands and rotor core to be measured closely firmly can be connected on tapered sleeve, ensure the accuracy of testing result.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model; Fig. 2 is the schematic diagram that is provided with the rotating shaft of frustum; Fig. 3 is the structural representation of tapered sleeve; Fig. 4 is the vertical view of Fig. 3.
Number in the figure: 1 rotating shaft, 2 frustums, 3 tapered sleeves, 4 open slots, 5 rotor cores.
Below pass through embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
Embodiment:
Embodiment: in conjunction with Fig. 1-4, be installed with and the frustum 2 of the truncated cone-shaped of rotating shaft coaxial line in the periphery at rotating shaft 1 middle part, and setting is socketed in the tapered sleeve 3 of frustum 2 outsides, the endoporus of tapered sleeve is the truncated cone-shaped of mating with frustum, be that the outer peripheral face of frustum and the endoporus of tapered sleeve can accurate accurately coordinate after grinding machine fine finishining, accurately coordinate and the outer peripheral face of tapered sleeve 3 and the endoporus of rotor core are same, in order to make tapered sleeve can expand (being that external diameter can be expanded), body at tapered sleeve 3 axially offers 2-8 road open slot 4 along it, these open slots distribute along the circumferencial direction of tapered sleeve 3 etc. point, and the length of each open slot is 3/4-4/5 of tapered sleeve height.Shown in Fig. 3,4, the outer peripheral face of tapered sleeve is step circular shaft shape, step surface plays the effect spacing to rotor core, prevent from when rotor core is socketed on tapered sleeve sliding onto the other end from one end, open slot provides surplus for the expansion of tapered sleeve external diameter, in use, first tapered sleeve 3 is socketed on frustum, then rotor core 5 is socketed on tapered sleeve, if three is more closely cooperated, only need knock rotating shaft along the axis direction of rotating shaft from the large end of frustum, frustum 2 gos deep in the endoporus of tapered sleeve 3, and three coordinates closelyr.
Claims (2)
