The guide wheel 24 is slidably connected to the sleeve 22 through the connecting rod 23 so that the guide wheel 24 abuts against the thickness measuring sensor 25.

[0029] During operation, the workpiece is guided into the cavity 1 by the feeding guide assembly 2. When the guide wheel 24 rolls against the surface of the workpiece, the guide wheel 24 is slidably connected to the sleeve 22 via the connecting rod 23, thereby causing the guide wheel 24 to contact the thickness sensor 25. Since the thickness sensor 25 is a mechanical thickness gauge, it typically includes a retractable measuring probe. The thickness of the workpiece is calculated by measuring the mechanical displacement generated by the probe in contact with the guide wheel 24. Therefore, it has the characteristics of fast response, high sensitivity, and high measurement accuracy, and can respond to the input signal in a very short time and accurately record the change in thickness value. This utility model adopts contact-type accurate measurement of workpiece thickness, effectively improving the measurement accuracy and grinding quality of the workpiece.
