Device for rapidly detecting circular saw tools

Abstract

The utility model discloses a device for rapidly detecting circular saw tools, and relates to the field of electric tools. The device comprises a hollow detection table, a to-be-detected tool is placed at the upper end of the detection table, a saw blade detection through groove is formed in the upper end of the detection table, the to-be-detected tool comprises a saw blade, and when the to-be-detected tool is placed at the upper end of the detection table for detection, the lower end of the saw blade can penetrate through the saw blade detection through groove to stretch into the detection table. A plurality of detection holes are formed in the saw blade at intervals along the same circumference, an infrared transmitter is arranged on one side, located in the width direction of the saw blade detection through groove, in the detection table, an infrared receiver is arranged on the other side, and when the saw blade rotates, infrared light beams between the infrared transmitter and the infrared receiver can sequentially penetrate through the detection holes. Central angles formed between the circle centers of the adjacent detection holes and the circle center of the saw blade are not equal. According to the invention, manual detection is changed into tool equipment detection, so that the detection accuracy and efficiency are improved, and serious consequences caused by the fact that unqualified products flow to the market are avoided as far as possible.
