Problems solved by technology

[0002] Grinding wheels, especially superhard grinding wheels, are commonly used for roller dressing. The initial position of the dressing needs to be very accurate. The commonly used method is the ultrasonic automatic detection method. After the grinding wheel and the roller are close, the gap becomes smaller, and the sound wave changes, so as to determine the relative position of the grinding wheel and the roller. The structure is complex and the precision is not high

Embodiment 1

[0011] A method for measuring the initial position of a grinding wheel and a dressing roller of a numerical control grinding machine, which is characterized in that: a sensor 2 is installed on the roller 1, the signal of the sensor 2 is connected to the numerical control system, the roller 1 does not rotate during measurement, and the grinding wheel 3 rotates on a moving guide rail 4. Slowly approach the roller 1 under the drive. At the moment when the grinding wheel 3 is in contact with the roller 1, the roller 1 is driven to rotate by the friction of the grinding wheel 3. The sensor 2 detects that the signal of the rotation of the roller 1 is transmitted to the numerical control system, and the numerical control system immediately stops the grinding wheel 3 and the roller. 1, and the CNC system records the position of the grinding wheel and the roller at that moment, which is the initial position of the grinding wheel and the dressing roller of the CNC grinding machine.

Embodiment 2

[0013] A method for measuring the initial position of a grinding wheel and a dressing roller of a numerically controlled grinding machine, characterized in that: a sensor 2 is installed on the grinding wheel 3, the signal of the sensor is connected to the numerical control system, and during measurement, the rolling wheel 1 rotates, the grinding wheel 3 does not move, and the grinding wheel 3 is moving Under the action of the guide rail 14, it slowly approaches the roller 1. At the moment when the grinding wheel 3 is in contact with the roller 1, the grinding wheel 1 rotates by friction. The sensor 2 detects the signal of the rotation of the grinding wheel 1 and transmits it to the CNC grinding machine. The numerical control system immediately stops the contact between the grinding wheel 3 and the roller 1. At the same time, the CNC system records the position of the grinding wheel and the roller at that moment, which is the initial position of the grinding wheel and the dressin...

Abstract

The invention belongs to mechanical measurement methods, and particularly relates to a method for measuring initial positions of a grinding wheel of a numerical control grinder and a dressing roller. The method is characterized in that a sensor is disposed on the roller; signals of the sensor are connected with a numerical control system; during measurement, the roller does not rotate, and the grinding wheel rotates to get close to the roller slowly; in a moment that the grinding wheel is in contact with the roller, the roller is driven to rotate by the grinding wheel through friction; the sensor detects a signal of roller rotation and transmits the signal to the numerical control system; the numerical control system immediately enables the grinding wheel to stop getting close to the roller, and simultaneously records relative positions, namely the initial positions of the grinding wheel of the numerical control grinder and the dressing roller, of the grinding wheel and the roller at the moment. Due to the fact that the diameter of the roller is quite small generally and can be driven by the friction in case of slightly contacting with the grinding wheel, as long as the speed of relative movement between the grinding wheel and the roller is low enough, the initial positions of the grinding wheel of the numerical control grinder and the dressing roller can be measured accurately. The method is simple, reasonable, high in accuracy and low in cost.
