Description

Technical Field

[0001] The utility model relates to the technical field of saw blade detection, and specifically relates to a saw blade tooth detection device. Background Technique

[0002] A saw blade is a tool for cutting, usually installed on a hand saw or a table saw, and realizes the cutting of an object by pulling back and forth. A saw blade consists of a series of closely arranged saw teeth, which are usually made of metal, such as carbon steel, alloy steel or other materials with higher hardness. According to different uses, saw blades can have different specifications and tooth shapes, for example, for cutting wood, metal or other materials.

[0003] The detection of saw blade teeth is very important in the production process of saw blades because it directly affects the cutting effect. The following are several key detection items:

[0004] The geometric shape of the saw teeth: The geometric shape of the saw teeth must meet the design requirements, such as common shapes like triangles, trapezoids, circles, etc. This requires measurement and inspection with special instruments.

[0005] The sharpness of the saw teeth: The saw teeth must be sharp to effectively perform cutting. This is usually evaluated through visual inspection and actual cutting tests.

[0006] The hardness of the saw teeth: The saw teeth need to have a certain hardness to maintain their sharpness and durability. Hardness is usually expressed by Rockwell hardness HRC and can be detected by a hardness tester.

[0007] The density of the saw teeth: The density of the saw teeth determines the cutting speed and accuracy. Generally speaking, the higher the density, the faster the cutting, but some accuracy may be sacrificed. This needs to be determined according to specific applications.

[0008] The coating of the saw teeth: If the saw teeth have a coating, the adhesion and corrosion resistance of the coating need to be detected. This can be carried out through methods such as salt spray tests and coating thickness measurements.

[0009] The above are some basic saw tooth detection items. In actual applications, other detection items may need to be added or some detection items may need to be reduced according to specific situations.

[0010] Currently, the detection of saw blades mainly adopts manual detection, that is, the measurement personnel manually hold the measuring tool against the inside of the saw teeth of the saw blade and hold a flashlight to irradiate and observe the error size between the saw teeth and the measuring tool. This method has a slow measurement speed, cumbersome measurement operations and large errors. Therefore, a saw blade tooth detection device is needed. Content of the Utility Model
