Background technology
Hexagonal is top is a kind of conventional tail spindle, this top axle body has Morse's taper, and top large end has six circumferentially uniform facets, these six faceted equal and opposite in directions, angle of inclination is identical, formation six angles and these six facets are connected successively.At present, general first by dividing head calibration, then grind this six facets by emery wheel, normal appearance six faceted not of uniform size, discrepant situations of skewness or angle of inclination after grinding, so just cause reaching requirement on machining accuracy, be badly in need of solving above-mentioned technical barrier for this reason.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of hexagonal top method for grinding, to ensure top six the faceted machining accuracies of hexagonal by the method.
Technical scheme of the present invention is as follows: the top method for grinding of a kind of hexagonal, is characterized in that comprising the steps:
Step a: the accessory (1) selecting a corresponding size according to the external diameter of hexagonal top (G), this accessory is positive six prism structures, its manufactured materials is high-carbon steel or iron, and six faces of accessory (1) are working face, and the centre bore (1a) of accessory (1) is and the top Mo Shi taper hole coordinated;
Step b a: outer surface of accessory (1) and sinusoidal disk (2) upper surface are fitted, and is fixed by magnetic force, and the centre bore (1a) of accessory (1) is held upward greatly; The lower end of described sinusoidal disk (2) is directly supported on base (3), and sinusoidal disk (2) middle part is supported on base (3) by slip gauge (4), so just can be adjusted the luffing angle of sinusoidal disk (2) by the height of slip gauge (4), and base (3) is fixed on the end face of workbench (5); The both sides of described sinusoidal disk (2) are provided with tension bar (6), lock-screw (7) is equipped with in the bar hole on this tension bar top, this lock-screw is fixed on the corresponding side surface of sinusoidal disk (2), and the bottom of tension bar (6) and base (3) are hinged, so just by tension bar (6), sinusoidal disk (2) is compressed;
Step c: top for hexagonal (G) is contained in the centre bore (1a) of accessory (1), top centre bore (1a) tight fit with accessory (1) of this hexagonal, then first facet in grinding hexagonal top (G) is carried out by emery wheel (8);
Steps d: after having ground a facet of hexagonal top (G), rotate accessory (1) again, the corresponding flat of accessory (1) and sinusoidal disk (2) upper surface is made to fit and be fixed by magnetic force, then by second facet in emery wheel (8) grinding hexagonal top (G); By that analogy, until ground six facets in hexagonal top (G).
Because the accessory (1) adopted in this method is positive six prism structures, so ensure hexagonal top (G) upper six faceted equal and opposite in directions, angle of inclination and circumferentially even well, thus ensure hexagonal top (G) upper six faceted requirement on machining accuracy, and this method for grinding is implemented simply, conveniently, is effectively overcomed the defect of traditional method for grinding.
In order to reduce the difficulty of processing of accessory (1), six planes of described accessory (1) all have a groove (1b), and this groove runs through the two ends of accessory (1); The center of described accessory (1) end face has a groove (1c), this groove is communicated with the small end of described centre bore (1a), and the aperture of groove (1c) is greater than the aperture that centre bore (1a) is held greatly, and the degree of depth of groove (1c) is 2mm.
Beneficial effect: because the accessory adopted in this method is positive six prism structures, so ensure top upper six the faceted equal and opposite in directions of hexagonal, angle of inclination and circumferentially even well, thus ensure top upper six the faceted requirement on machining accuracy of hexagonal, and this method for grinding is implemented simply, conveniently, is effectively overcomed the defect of traditional method for grinding.
