Automatic control device and method for through-feed grinding of centerless grinding machine

Abstract

The invention relates to an automatic control device and method for through-feed grinding of a centerless grinding machine. The defect that in the prior art, feeding compensation fine adjustment of a guide wheel frame and feeding of a correction knife are operated manually, so that dependence on the techniques and proficiency of operators is high is overcome. The automatic control device comprises a guide wheel frame feeding compensation fine adjustment device, a grinding wheel correction value measurement feedback device, a guide wheel correction value measurement feedback device, an online workpiece automatic measurement feedback device and a discharging distribution conveying belt and an automatic control system. The grinding wheel correction value measurement feedback device and the guide wheel correction value measurement feedback device adopt the same structure and each comprise a correction transmission mechanism and a correction measurement mechanism. Automatic adjustment is achieved, the limitation of techniques of workers is overcome, finished workpieces are measured online and automatically, a controller is used for controlling adjustment, adjustment is rapid, the phenomenon of wrong operation or mixing of rejects is lowered, the overall quality of the workpieces is guaranteed, and meanwhile machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of bearing ring processing, in particular to an automatic control device and control method for through-grinding of a centerless grinder. Background technique [0002] For the outer diameter machining of bearing rings (or other metal workpieces similar to outer circle machining), centerless grinding machines are generally used for through-type grinding because of high process requirements and large batches. The existing centerless grinding machine comprises a grinding wheel installed on the grinding wheel shaft, a guide wheel installed on the guide wheel shaft, a workpiece supporting plate, a grinding wheel corrector, a guide wheel corrector and a guide wheel frame feeding mechanism. [0003] During grinding, the workpiece is continuously placed between the grinding wheel, the guide wheel and the supporting plate, and is connected with the workpiece on the external material path of the feed end. The guide w...

Problems solved by technology

[0005] The invention solves the defects in the prior art that the feed compensation fine-tuning of the guide wheel frame and the feed of the correction knife are all manually operated, and the technology and proficiency of the operator are highly dependent on the defect, and provides an automatic control device for centerless grinding machine through-grinding And the control method, the fine adjustment of the feed compensation of the guide wheel frame and the correction of the knife feed are realized automatically, and the limitation of manual technology is overcome

[0006] The invention also solves the problems of independent operation and manual sampling inspection of the guide wheel frame and the correction knife in the prior art, which not only increases the time for each adjustment, but is also prone to misoperation or untimely sampling inspection, resulting in the mixing of defective products and affecting the overall quality. , to provide an automatic control device and control method for centerless grinding machine through-grinding, which conducts automatic sampling inspection on workpieces, and automatically realizes the adjustment of the guide wheel frame and the correction knife according to the sampling inspection results, the adjustment is quick, and the phenomenon of misoperation or defective product mixing can be reduced , to ensure the overall quality of the workpiece

[0007] The present invention also solves the defects in the prior art that operators need to pay attention to sampling inspection of workpieces at all times, and manually adjust according to the results of sampling inspection at any time, which cannot improve the labor productivity of personnel. It provides an automatic control device and control method for centerless grinding machine through grinding, which Carry out spot checks on the workpiece, and automatically adjust the feed compensation of the guide wheel frame and the feed correction of the correction knife according to the spot checks. The whole process is automated and the processing efficiency is improved.
