As another scheme, in above-mentioned sawtooth grinding lathe, described elastic support comprises four rubber-like poles, and two poles are connected in a wherein end of grinding head assembly, and other two poles are connected in an other end of grinding head assembly.Can keep the stress balance of grinding head assembly and stable motion by four poles.
In above-mentioned sawtooth grinding lathe, described drive unit is the cam that is connected in the motor on the matrix and is connected with machine shaft, and above-mentioned grinding head assembly contacts with the cam edge.
In above-mentioned sawtooth grinding lathe, described grinding head assembly bottom has the contact site of protrusion, and this contact site contacts with above-mentioned cam edge.
In the time of the two contact, this moment, spring steel plate just produced deformation, had just realized relative motion with regard to this grinding head assembly, after cam turns over, spring steel plate restores, grinding head assembly is under the drive of spring steel plate, and grinding head assembly is also got back to original position simultaneously, like this, under the situation of the rotation that cam does not stop, spring steel plate is repeating to be out of shape, and restores again, and grinding head assembly has been realized reciprocal motion at this point simultaneously.
In above-mentioned sawtooth grinding lathe, described motor is the adjustable speed reducing motor.Obviously can carry out the adjustment of operating rate according to the situation of reality by adjustable speed motor, to reach best operating efficiency.
In above-mentioned sawtooth grinding lathe, described drive unit also comprises power transmission shaft, drive and driving-belt, all is fixed with a drive on the rotating shaft of motor and the power transmission shaft, and driving-belt is enclosed within on above-mentioned two drives, and above-mentioned cam is connected on the power transmission shaft.
Compared with prior art, the utlity model has following advantage: 1, owing to be provided with elastic support between the utility model grinding head assembly and the matrix, therefore, the utility model course of work does not have any wearing and tearing, the precision height of reconditioning, and also operating efficiency is higher.2, can keep the stress balance of grinding head assembly and stable motion by four poles, stability in use height and convenient installation, long service life.
