Fault self diagnosis device for transfer machine equipment

Abstract

The invention relates to a fault self diagnosis device for transfer machine equipment. The fault self diagnosis device includes a controller, a frequency converter, an absolute type encoder, a rear limit switch, a front limit switch and a displacement sensor; the rear limit switch and the front limit switch are arranged at the rear end and the front end of a conveying rail on a transfer machine supporting base; the absolute type encoder is mounted on the main gear shaft of a gearbox of a transfer machine; the displacement sensor is mounted just below the tail end of a stretchable fork of the transfer machine when the stretchable fork stretches out to a limit position; the controller is electrically connected with the absolute type encoder, the rear limit switch, the front limit switch and the displacement sensor; and the controller is connected with the driving motor of the transfer machine through the frequency converter. With the fault self diagnosis device for transfer machine equipment of the invention adopted, the abrasion of the gear box and the sinking of the tail end of the stretchable fork of the transfer machine can be monitored and diagnosed, and therefore, early warning can be performed before corresponding faults occur on the transfer machine, and therefore, the frequency of manual periodic maintenance and repair can be decreased.

Description

technical field [0001] The present invention covers the technical field of automation equipment, especially a fault diagnosis device for a transfer machine. Background technique [0002] In the process of automobile production and manufacturing, the failure of the equipment in the production line may cause the entire production line to stop running, which will cause huge losses to the automobile manufacturer. Therefore, it is of great importance to ensure the continuous operation of key equipment in the automobile production line. Practical significance. As a kind of automatic transfer equipment, the transfer machine is mainly used for transferring materials between wire bodies in the automobile assembly line, so as to realize the exchange of materials between different wire bodies. As the transfer machine is the key equipment in the automobile assembly line, its failure will cause the entire automobile assembly line to stop running, so it is very practical to design a faul...
