Abstract
Disclosed is a rotor punching sheet overlapping dummy shaft device. The device comprises a dummy shaft, damping sheets, rotor punching sheets, a damping strip and keys. The structural characteristics of the device are that the dummy shaft is provided with the keys, and the plurality of rotor punching sheets are positioned on the dummy shaft through the keys. The damping sheets overlapped at the two sides of the rotor punching sheets are connected to the dummy shaft. The damping strip disposed at the outer side of the damping sheets are welded inside holes of the rotor punching sheets. In the conditions that the rotor punching sheets are overlapped onto the dummy shaft as simple as possible, the rotor overlapping process is more convenient and production efficiency is improved, so that the rotor punching sheets are difficult to be damaged, and upkeep and maintenance cost is reduced.
Description
Technical field
The utility model relates to a kind of dummy shaft device, relates in particular to a kind of rotor punching and repeatedly presses dummy shaft device.
Background technology
Normal conditions rotor punching repeatedly presses in frock dummy shaft to adopt ring shaped slot, and keyway length in dummy shaft is too short, and rotor punching can not well be located and repeatedly also can causing unnecessary trouble in pressure process in the time repeatedly pressing.This has not only greatly improved the possibility that rotor punching damages, and has increased the difficulty of producing and keeping in repair.
Summary of the invention
The purpose of this utility model is to provide a kind of rotor punching repeatedly to press dummy shaft device, and it has advantages of simple in structure and uses easy to operate.
The utility model is achieved like this, it comprises dummy shaft, damping sheet, rotor punching, amortisseur bar and key, it is characterized in that dummy shaft is provided with key, several rotor punchings are located by connecting on dummy shaft by key, fall the damping sheet that is pressed in rotor punching both sides and be also connected on dummy shaft, the amortisseur bar that is positioned at damping sheet outside is welded on the hole of rotor punching.
Technique effect of the present utility model is: the utility model repeatedly presses dummy shaft structure to try one's best in simple situation at rotor punching, and rotor is changed, and pressure process is more convenient enhances productivity, and reduces possibility and repair and maintenance cost that rotor punching damages.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is rotor coil support assembling schematic diagram:
Dummy shaft 2, damping sheet 3, rotor punching 4, amortisseur bar 5, key in the drawings, 1.
Embodiment
In Fig. 1, section A-A adopts the 3 equal portion of groove structures, makes punching more easily install and ensure radial location; The structure of section B-B screwed hole, can ensure rotor core axial dimension, because axial dimension can be fixed by screw thread, can change axial dimension by the mode that increases back-up block, thereby the versatility of dummy shaft is strengthened.
In Fig. 2, the utility model is achieved like this, it comprises dummy shaft 1, damping sheet 2, rotor punching 3, amortisseur bar 4 and key 5, it is characterized in that dummy shaft 1 is provided with key 5, several rotor punchings 3 are located by connecting on dummy shaft 1 by key 5, the damping sheet 2 that is repeatedly pressed in rotor punching 3 both sides is also connected on dummy shaft 1, and the amortisseur bar 4 that is positioned at damping sheet 2 outsides is welded on the hole of rotor punching 3.When this dummy shaft 1 can better repeatedly be pressed rotor punching 3 and prevent that rotor punching 3 from repeatedly pressing, punching enters groove, causes the distortion of rotor punching 3 and affects working (machining) efficiency.Dummy shaft 1 adopts good 45 steel of comprehensive mechanical property, by dummy shaft 1 and key 5, rotor punching 3 is positioned.Key 5 is arranged on to the location that facilitates rotor punching 3 on dummy shaft 1, damping sheet 2 and rotor punching 3 are arranged on dummy shaft 1 successively, after rotor punching 3 discharges, put into damping sheet 2 pressure that changes, then amortisseur bar 4 are pressed in the hole of rotor punching 3 and weld.
