Compensating measurement method of polishing wheels and device therefor

Abstract

The invention discloses a compensating measurement method of polishing wheels and a device therefor; with the assistance of a speed measuring motor, a contact wheel which contacts with and rotates synchronously with the polishing wheels is adopted to measure wear condition of the polishing wheels; the device comprises the contact wheel which contacts with the polishing wheels of a polishing machine and the speed measuring motor which is coaxially connected with the contact wheel for measuring abrasion loss of the polishing wheels; a signal output end of the speed measuring motor is connected with a radio transmission module by a input voltage converter for converting the measured abrasion loss into voltage signals and transmitting the voltage signals to a control master computer by the radio transmission module; the signal input terminal of the control master computer is connected with a radio receiving module by the output voltage converter for receiving radio-frequency signals and calculating obtained compensation dosage and compensating the polishing wheels by control programs. In the invention, accurate compensation information for the master computer and accurate compensatingcontrol on the polishing wheels are provided by real-time monitoring of the actual magnitude of abrasion loss of the polishing wheels so as to meet better technical requirements.

Description

technical field [0001] The invention relates to the technical field of polishing technology, in particular to a method for compensating and measuring a polishing wheel and a device thereof. Background technique [0002] The traditional polishing process is to install the workpiece on the push-pull fixture during the whole process. When the polishing wheel is worn, the height of the center of the polishing wheel is manually lowered to ensure proper contact between the polishing wheel and the workpiece to meet the polishing process requirements. However, due to the large error of manual adjustment and frequent adjustment, it has a great impact on the polishing quality and effect. [0003] In the field of CNC polishing, all movements of the polishing wheel and workpiece fixture are precisely controlled by programs and parameters. In the continuous polishing process, since the polishing wheel is constantly worn and becomes smaller, how to accurately feed back this real-time cha...

Problems solved by technology

The disadvantage is that since the pressure sensor is not in direct contact with the polishing wheel and detects, it is prone to mismeasurement, and the accuracy of the measurement result is not high, which leads to wrong compensation and affects the polishing effect and processing quality

In addition, the detection signal of the device is transmitted to the controller through wired transmission. For a complex polishing machine, the wiring is cumbersome, and the transmission line is easy to be damaged during the operation of the polishing machine.
