Description

technical field [0001] The invention relates to the field of mechanical detection, in particular to an automatic detection device for cylindrical pin machines. Background technique [0002] Pins are generally used to connect, lock parts or for assembly positioning, and can also be used as parts of safety devices. In the mechanical field, pins are mainly used for assembly positioning, and can also be used as overload shear connections in connection and relaxation level safety devices. The cylindrical pin is fixed in the pin hole with a slight interference. [0003] The type of pin is selected according to its working requirements in use. The diameter of the pin used for connection can be determined empirically according to the structural characteristics of the connection, and the strength check should be done if necessary. The diameter of the positioning pin can be determined according to the structure. The length of the pin in each connector is about 1-2 times its diamet...

AI Technical Summary

Problems solved by technology

[0007] Although the above-mentioned prior art has improved production efficiency compared with manual detection, the feeding mechanism of the above-mentioned device uses a funnel placed above the equipment, and the material is unloaded by the gravity of the cylindrical pin itself. There are several problems in this unloading method. First of all, if there are a large number of straight pins in the funnel, it is easy to cause blockage, and the feeding is not smooth. Although there is a vibrator, if the vibrator is used to vibrate when the block is blocked, the straight pins will only be blocked at the feeding port, which is very inconvenient. , and the material is slowly unloaded by the gravity of the cylindrical pin itself, the efficiency is not high. Although the length sensor can effectively measure the length of the cylindrical pin, it needs the length sensor to clamp both ends of the cylindrical pin for measurement. After the measurement is completed, the cylindrical pin needs to be returned for measurement. There are too many mechanical actions in the process, which wastes time and further reduces the detection efficiency
