Abstract
The utility model relates to a be used for fine processing of electricity runout rotor shaft to grind top, the grinding head end matches through the recess of quenching steel ball, steel ball end cover and steel ball base and morse taper shank terminal surface, and O type rubber circle is located between grinding head and morse taper shank terminal surface recess wall, and morse taper shank couples with the lathe tailstock. The advantages are that: the utility model discloses a grind top, reform transform the circularity and the roughness that the centre frame improved the centre bore, improve the key process quality control in the rotor shaft course of working, improve the machining precision of rotor shaft simultaneously.
Description
Technical Field
The utility model relates to a can be applicable to rotor shaft finish machining back finished product total length and reach more than or equal to 3744mm, the iron core is directly more than or equal to footpath phi 1000mm, and finished product weight is more than or equal to 6258 kg's grinding is top, belongs to the top field of making of grinding.
Background
Compared with other rotor shafts, the Terry electric jumping rotor shaft has the advantage that the detection requirement of the Terry electric jumping detection instrument is increased when the Terry electric jumping rotor shaft is used as a core part of the motor. The detection requirement of the electrical runout is high, so that very high requirements are provided for the material, heat treatment, finish machining, detection and the like of the rotor shaft, the project is put into the Finland factory production by a famous company in the international motor field due to low product yield, and at present, no manufacturer manufactures the product at home and no corresponding processing tool exist.
Disclosure of Invention
The design purpose is as follows: the grinding center is designed to be suitable for the grinding center with the length of more than or equal to 3744mm, the diameter of a shaft body of more than or equal to phi 320, the diameter of an iron core of more than or equal to phi 1000 and the weight of a finished product of more than or equal to 6258 kg.
The design scheme is as follows: in order to achieve the above design objectives. The processing aspect of the bentlet is as follows: the precision of the rotor shaft is ensured from the following aspects mainly according to the requirement characteristics of electric bounce, and firstly, a reasonable and scientific process scheme is compiled to guide the production process: the method comprises the following process flows of rough machining, semi-finish machining, low-temperature stress-eliminating heat treatment, center hole trimming, finish turning, key slot milling, center hole finishing, iron core grinding, iron core hot embedding, rough grinding, finish grinding, polishing and extruding, electric jump detection and packaging and delivery. The utility model discloses the grinding that designs in the course of working is top, not only improves the circularity and the roughness of centre bore, improves the key process quality control in the rotor shaft course of working moreover, improves the machining precision of rotor shaft.
The technical scheme is as follows: a grinding center for finish machining of an electric runout rotor shaft is characterized in that the tail end of a grinding head is matched with a groove in the end face of a Morse taper shank through a quenched steel ball, a steel ball end cover and a steel ball base, an O-shaped rubber ring is located between the grinding head and the groove wall in the end face of the Morse taper shank, and the Morse taper shank is connected with a tailstock of a machine tool.
The utility model discloses a grind top, reform transform the circularity and the roughness that the centre frame improved the centre bore, improve the key process quality control in the rotor shaft course of working, improve the machining precision of rotor shaft simultaneously.
Drawings
Fig. 1 is a schematic view of a grinding tip, 1. a grinding head; 2. a Morse taper shank; quenching the steel ball; 5, a steel ball base; and 6. an O-shaped rubber ring.
Detailed Description
Example 1: reference is made to figure 1. A grinding center for finish machining of an electric jumping rotor shaft is characterized in that: the tail end of the grinding head 1 is matched with a groove on the end face of the Morse taper shank 2 through a quenching steel ball 3, a steel ball end cover 4 and a steel ball base 5, an O-shaped rubber ring 6 is positioned between the grinding head 1 and the groove wall on the end face of the Morse taper shank 2, and the Morse taper shank 2 is connected with a tailstock of a machine tool.
The grinding head 1 is filled with grinding agent on the conical surface, the machine tool tailstock sleeve moves forwards to enable the grinding head 1 to extrude and grind the conical surface and the central hole, the grinding head is in floating connection through the internal quenching steel ball 3 and the O-shaped rubber ring 6, and when the grinding head is used, the deviation of the tailstock and the machine tool such as non-concentricity is corrected, so that the purpose of improving the surface roughness of the central hole is achieved.
It is to be understood that: although above-mentioned embodiment is right the utility model discloses a design has done more detailed word description, but these word descriptions, are only right the utility model relates to a simple word description of idea, rather than right the utility model relates to a restriction of idea, any do not surpass the utility model relates to a combination, increase or the modification of idea all fall into the utility model discloses a within the protection scope.
