Abstract
The invention relates to a clamp for assembling and expanding a conducting bar of a motor rotor, especially to a clamp for assembling and expanding the conducting bar of the copper bar rotor of a motor, and aims at solving the problems that the length of the rotor bar stretching out of two ends of a rotor core is determined through marking lines when a present electric machine copper rotor bar is assembled and expanded, operation is complex, the rotor bar cannot be accurately positioned, lengths, stretching out of two ends of a rotor core, of the rotor bar are different, two ends of the rotor bar are not fixed when the rotor bar is expanded, and the rotor bar is easy to slip off a rotor core groove when the expanding force is over large or the direction is inclined. A circular-ring-shaped non-driving end pressure plate is connected to a driving end pressure plate through four screws, the inner circle of the non-driving end pressure plate is provided with a circular-ring-shaped stage, and four bolts are uniformly connected to the periphery of the ring stage. By adopting the clamp, the labor intensity is reduced, positioning precision of the rotor bar and the expanding effect are improved, the size is small, the weight is low, the floor space is small, and the clamp is suitable for assembling and expanding a batch of copper rotor bars at the same time.
Description
Technical field
The present invention relates to the special mechanical equipment of industry of motor production, relate to the assembling of copper bar rotor sliver and swelling fixture on a kind of railcar traction electric machine specifically.
Background technology
At present, there is following shortcoming in the copper bar rotor of motor sliver assembling that known or electrical machinery plant is using and swelling process: 1. line determines that sliver stretches out rotor iron core two ends length, sliver on position need to be observed when every root sliver wears bar, operate loaded down with trivial details, sliver location is inaccurate, stretches out iron core two ends different in size; 2. during swelling, sliver two ends are not fixed, and tension force is excessive, not timing sliver in direction easily skids off from rotor iron core slot, need to, with hand by tight for sliver two ends handle, operate loaded down with trivial details during swelling, and dangerous, it is not tight that sliver is swollen.
Summary of the invention
It is an object of the invention to for above-mentioned deficiency, and a kind of registration provided, clamping puts in place, safety, and the low motor rotor conducting bar assembling of labour intensity and swelling fixture.
The technical solution of the present invention is: the non-transmision end pressing plate of annular is connected on transmission side pressure plate by four screw rods, and the inner circle of non-transmision end pressing plate is provided with an annular step, is circumferentially evenly connected with four bolts on this annular step.
The excircle dimension of the non-transmision end pressing plate described in the technical solution of the present invention is less than rotor iron core external diameter size, and inner circle size is greater than rotor iron core shelves diameter of axle size.
On transmission side pressure plate described in the technical solution of the present invention, four circular holes of connecting screw rod are corresponding with four vent locations on rotor iron core.
The present invention adopts to install non-transmision end pressing plate location sliver at rotor iron core non-transmision end, and transmission end screw rod compresses sliver through rotor iron core ventilation hole and non-transmision end pressing plate by fastening nut; Instant invention overcomes the assembling of existing traction electric machine copper bar rotor sliver loaded down with trivial details with swelling process operation, location out of true, swelling weak effect, unsafe drawback, there is the assembling of traction electric machine copper bar rotor sliver and swelling is flexible and efficient, registration, swelling are effective, safe advantage, alleviate the labour intensity of workman simultaneously, improve sliver positioning precision and swelling effect, the fixture volume of the present invention is little, weight is light, floor space is little, is convenient to seriation and mass production.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention comprises transmission side pressure plate 1 and non-transmision end pressing plate 2, and transmission side pressure plate 1 and non-transmision end pressing plate 2 are all annular steel plates, are connected by four screw rods 3 between transmission side pressure plate 1 and non-transmision end pressing plate 2, and fixes with nut 4, on transmission side pressure plate 1, four circular holes of connecting screw rod 3 are corresponding with four vent locations on rotor iron core, the excircle dimension of non-transmision end pressing plate 2 is less than rotor iron core external diameter size, inner circle size is greater than rotor iron 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 transmission side pressure plate 1 side, is circumferentially evenly connected with four bolts 5 on this annular step, principle of work: the present invention is in use, can by the nut 4 on adjustment four screw rods 3, the axial location size being used between adjustment transmission side pressure plate 1 and non-transmision end pressing plate 2, equal to ensure that rotor iron core two ends length is stretched out at sliver two ends, by four bolts 5 on non-transmision end pressing plate 2, non-transmision end pressing plate 2 is fixed on rotor iron core non-transmision end trim ring, make the sliver location worn in rotor iron core slot, on transmission side pressure plate 1, align with four ventilation holes on rotor iron core in four circular holes of connecting screw rod 3, transmission side pressure plate 1 and non-transmision end pressing plate 2 are linked together by fastening nut 4 by screw rod 3 through these four circular holes, sliver in rotor iron core slot is compressed.
