Size control system used for dual-face grinding machine and safe grinding detection method

Abstract

The invention provides a size control system used for a dual-face grinding machine and a safe grinding detection method; wherein, the size control system used for the dual-face grinding machine comprises a displacement sensor and a size control meter; the displacement sensor is electrically connected with the control size meter; a communication end of the size control meter is electrically connected with a first communication end of a controller; a second communication end of the controller is electrically connected a communication end of a touch panel. According to the system, the size control meter is set by the operation of the touch panel, so that it is simple and rapid, and the damage, caused by a severe environment or frequent operation, of the size control meter is avoided; the damage, caused by abnormal placement, of a workpiece is avoided by adding lowering position judgement; an upper grinding disc can make flexible contact with the workpiece after rotation by lowering condition control, so that the deformation, caused by great pressure rotation directly on the workpiece, of the workpiece is avoided; and the problem of the damage, caused by the abnormal placement of the thin and small workpieces, of parts or grinding machine components is avoided by adding a workpiece abnormal placement prompt function.

Description

technical field [0001] The invention relates to the technical field of grinding size control of a double-sided grinder, in particular to a size control system and a safe grinding detection method for a double-sided grinder. Background technique [0002] The processing principle of the double-sided grinding machine is to place the workpiece in the planetary wheel, driven by the center wheel, the planetary wheel meshes with the cylindrical pin of the lower plate and makes a circular motion, and at the same time, the upper and lower grinding discs rotate to grind the workpiece. The new generation of grinding machine has increased the size control part, combined with the CBN grinding wheel, the size control between discs can be realized. In this way, the displacement sensor (range 0-50mm, precision 0.5μm) and the control size instrument (LT20A / LT30 counter) suitable for the large displacement of this type of machine tool are very important. At present, an instrument imported fr...

Problems solved by technology

Now after manual placement, the inner ring servo motor is generally jogged at a low speed to drive the planetary wheel that loads the workpiece to rotate. However, when the cantilever with a limited stroke is swung out, the shield of the upper grinding plate with a diameter of 700mm to 1000mm will block part of the lower Grinding disc, it is difficult to see all the workpieces. It is inevitable that there will be abnormalities such as workpiece placement or overlapping. In this way, when the cycle processing is started, the workpieces will jump out, resulting in damage to the planetary wheel and CBN grinding wheel. The current is too high and the alarm stops

The damage to the planetary wheel cannot be repaired, and it takes several hundred yuan to redo it. The repair cost of a CBN grinding wheel worth tens of thousands of yuan is also very high. The impact of the servo motor and reducer will also affect the service life. This problem also needs to be solved urgently.
