Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the structural representation of the utility model difference teeth position adjusting device.
The specific embodiment
Poor teeth described in the utility model position adjusting device, the shaft shoulder of its drive mandrel 2 combines by screw 1 and nut 6 with frictional disk 7, and drive mandrel 2 is in hollow shaft 9, and its work axle head is connected with cutter spindle; Spline housing 3 puts together on spline housing 5, and two spline housings 3 are different with 5 numbers of teeth, carries out spline with drive mandrel 2, frictional disk 7 and is connected, and locking nut 4 is fixed it, and frictional disk 7 and hollow shaft 9 are by combining closing screw 8.Drive mandrel 2, frictional disk 7 are connected with 5 with corresponding spline housing 3 by two sections splines of the different numbers of teeth, and two sections splines can be thrown off respectively.According to the amount of phase difference, rotate the corresponding number of teeth respectively during use, can finish quantitatively accurately adjusting of tooth position.
