Description

A monitoring devices for aluminum alloy rotary furnace zero point deviation Technical Field The utility model relates to the technical field of aluminum alloy heating and heat treatment equipment, in particular to a monitoring device for zero deviation of an aluminum alloy rotary furnace. Background The rotation angle of the existing aluminum alloy rotary furnace is usually controlled by a servo motor, and the converter angle is calculated by relying on a pulse signal program. However, under the long-term continuous rotation working condition, an angle positioning error is easily generated due to mechanical abrasion or signal accumulation, so that zero point calibration is required to be performed through a sensor within a certain rotation range. At present, a single sensor (such as a limit switch) is generally adopted as a calibration element for zero point positioning of the equipment, but the technical scheme has the remarkable defect that when the calibration sensor fails due to failure or position deviation occurs due to mechanical installation deviation, the rotating zero point of the aluminum alloy rotary furnace generates positioning deviation, so that the workpiece positioning reference is misaligned, and further, safety accidents caused by collision with a furnace body, a furnace inner bracket or other workpieces when a robot grabs the workpieces can be caused. The core of the prior art is that zero point calibration is only performed through a servo motor, an independent monitoring mechanism for zero point positioning accuracy is lacked, a single sensor is used as a unique detection element and is not capable of verifying the reliability of the working state of the sensor. When the sensor itself is abnormal, the system can not recognize the zero point deviation, so that the equipment can continuously run in the error positioning state, and not only can the economic losses of batch scrapping of workpieces, shutdown maintenance of a production line and the like be possibly caused, but also malignant accidents such as equipment damage, casualties and the like are more possibly caused by mechanical collision. Therefore, how to design a safe and reliable device capable of monitoring zero point positioning accuracy in real time and immediately early warning when deviation exceeds a threshold value becomes a technical problem to be solved in the field.
