Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grinding head detection, in particular to a wear detection device for a grinding head. Background Art
[0002] A grinding head is a general term for a small grinding tool with a handle, which is used in electric grinders, hanging grinders, and hand drills. There are many types, mainly ceramic grinding heads, rubber grinding heads, diamond grinding heads, emery cloth grinding heads, etc.
[0003] The long-term use of the grinding head will cause wear of the grinding head. Sometimes the wear marks of the grinding head are small and difficult to observe directly with the naked eye, but such wear will still affect the use of the grinding head. Therefore, it is necessary to inspect the grinding head regularly, that is, use a wear detection device to detect the wear condition of the grinding head.
[0004] Most of the existing wear detection devices place the grinding head at the displacement sensor. When the grinding head rotates, the displacement sensor measures the length of a fixed path to determine whether the grinding head is worn. However, since the grinding head is used frequently in workshops, the efficiency of detecting one by one is low. Moreover, if the displacement sensor used for detection fails and is not discovered in time, it is easy to cause errors in the detection results. Utility Model Content
