Abstract

The invention provides automatic frequency modulation equipment for a crystal, in particular to a full automatic frequency modulation machine for a columnar crystal, which comprises a frequency display window, an intelligent control platform, a grinding wheel, a feeding worktable, a clamping cylinder, a mounting soleplate, a signal lamp, a ratchet fixing plate, an electric cabinet, a crystal positioning seat, a buffering elastic seat, an automatic feed conveying assembly, an automatic feed conveying buffering system, an automatic clamping and frequency measuring assembly and an automatic grinding and frequency modulation system; the working principle lies in that when the automatic feed conveying assembly conveys the crystal to the set position, the clamping and frequency measuring assembly fixes the crystal within 10 minutes and measures the frequency simultaneously; at that time, a step motor of the automatic grinding and frequency modulation system drives a screw rod mould set in order that the grinding wheel approaches the columnar crystal to be ground and the frequency of the columnar crystal is always detected; and when the grinding wheel contacts the columnar crystal, the frequency of the columnar crystal has large change. At that time, the intelligent control platform with the processing and storing capacity considers that the grinding wheel contacts the columnar crystal; according to the difference value between the detected frequency of the columnar crystal and the target frequency and the grinding coefficient, the grinding time and the proceeding distance of thegrinding wheel are determined (through the precise matching between the step motor and the rolling ball screw rod mould set, the precision of the linear motion of the grinding wheel is controlled in 0.002 mm); when the first grinding is completed, the grinding time, the grinding length and the frequency rising value of the grinded columnar crystal are recorded; subsequently, a rough grinding.
