Abstract
Title of the present utility model is motor rotor conducting bar assembling and swelling fixture, relates to the assembling of copper bar rotor sliver and swelling fixture on a kind of traction electric machine.It mainly solve existing copper bar rotor of motor sliver assembling with swelling be adopt line to determine sliver stretches out rotor core two ends length, complex operation, sliver location is inaccurate, stretch out iron core two ends different in size, during swelling, sliver two ends are not fixed, the problem that during tension force excessive or poor direction, sliver easily skids off from rotor core groove.The utility model is that the non-transmision end pressing plate of annular is connected on driving end pressing plate by four screw rods, and the inner circle of non-transmision end pressing plate is provided with an annular step, and this annular step is circumferentially evenly connected with four bolts.The utility model alleviates the labour intensity of workman, improves sliver positioning precision and swelling effect, volume is little, lightweight, floor space is little, is applicable to carrying out the manufacture of copper bar rotor sliver in enormous quantities assembling and swelling simultaneously.
Description
Technical field
The utility model relates to the special mechanical equipment of industry of motor production, relates to the assembling of copper bar rotor sliver and swelling fixture on a kind of railcar traction electric machine specifically.
Background technology
At present, following shortcoming is there is: 1. rule and determine that sliver stretches out rotor core two ends length in the copper bar rotor of motor sliver assembling that known or electrical machinery plant is using and swelling process, sliver insertion position need be observed when every root sliver wears bar, complex operation, sliver location is inaccurate, and it is different in size to stretch out iron core two ends; 2. during swelling, sliver two ends are not fixed, tension force is excessive, poor direction time sliver easily skid off from rotor core groove, during swelling need with hand by sliver two ends tight, complex operation, dangerous, it is not tight that sliver is swollen.
Summary of the invention
The purpose of this utility model is for above-mentioned deficiency, and a kind of registration provided, and clamping puts in place, safety, and the low motor rotor conducting bar assembling of labour intensity and swelling fixture.
Technical solution of the present utility model is: the non-transmision end pressing plate of annular is connected on driving end pressing plate by four screw rods, the inner circle of non-transmision end pressing plate is provided with an annular step, and this annular step is circumferentially evenly connected with four bolts.
The excircle dimension of the non-transmision end pressing plate described in technical solution of the present utility model is less than rotor core outside dimension, and inner circle size is greater than rotor core shelves diameter of axle size.
On driving end pressing plate described in technical solution of the present utility model, four circular ports of connecting screw rod are corresponding with the vent locations of four on rotor core.
The utility model adopts to install non-transmision end pressing plate location sliver at rotor core non-transmision end, and driving end screw rod compresses sliver through rotor core ventilation hole and non-transmision end pressing plate by fastening nut; It is loaded down with trivial details with swelling process operation that the utility model overcomes the assembling of existing traction electric machine copper bar rotor sliver, location inaccuracy, swelling weak effect, unsafe drawback, there is the advantage that the assembling of traction electric machine copper bar rotor sliver and flexible and efficient, the registration of swelling, swelling are effective, safe, alleviate the labour intensity of workman simultaneously, improve sliver positioning precision and swelling effect, fixture volume of the present utility model is little, lightweight, floor space is little, is convenient to seriation and mass production.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises driving end pressing plate 1 and non-transmision end pressing plate 2, and driving end pressing plate 1 and non-transmision end pressing plate 2 are all annular steel plates, is connected between driving end pressing plate 1 and non-transmision end pressing plate 2 by four screw rods 3, and fixes with nut 4, on driving end pressing plate 1, four circular ports of connecting screw rod 3 are corresponding with the vent locations of four on rotor core, the excircle dimension of non-transmision end pressing plate 2 is less than rotor core outside dimension, inner circle size is greater than rotor core shelves diameter of axle size, the interior annulus of non-transmision end pressing plate 2 is provided with an annular step, this annular step is located at driving end pressing plate 1 side, and this annular step is circumferentially evenly connected with four bolts 5, operation principle: the utility model in use, can by the nut 4 on adjustment four screw rods 3, be used for adjusting the axial location size between driving end pressing plate 1 and non-transmision end pressing plate 2, equal to ensure that rotor core two ends length is stretched out at sliver two ends, by the bolt of four on non-transmision end pressing plate 25, non-transmision end pressing plate 2 is fixed on rotor core non-transmision end trim ring, make the sliver location penetrated in rotor core groove, on driving end pressing plate 1, four circular ports of connecting screw rod 3 align with the ventilation hole of four on rotor core, driving end pressing plate 1 and non-transmision end pressing plate 2 are linked together by fastening nut 4 through these four circular ports by screw rod 3, sliver in rotor core groove is compressed.
