Description

Technical Field

[0001] The utility model relates to the technical field of centerless grinders, in particular to an automatic centerless grinder. Background Art

[0002] A centerless grinder is a type of grinder that does not require the axis of the workpiece to be positioned for grinding. It is mainly composed of three mechanisms: a grinding wheel, an adjusting wheel, and a workpiece holder. The grinding wheel is actually responsible for grinding, the adjusting wheel controls the rotation of the workpiece and the feed speed of the workpiece, and the workpiece holder supports the workpiece during grinding. These three parts can be coordinated in several ways, but the principles are the same except for stopping grinding.

[0003] According to the description of a centerless grinder disclosed on the patent website (authorization announcement number: CN 219485120 U), "The utility model relates to the technical field of grinders, specifically a centerless grinder, including a screening component group arranged on the side of the grinder body, the screening component group is used to collect used coolant, the screening component group includes a top transfer box, a liquid outlet is arranged on one side of the top transfer box, a sleeve is arranged on one side of the liquid outlet, and a screen is arranged inside the sleeve. The utility model can quickly and effectively screen and collect coolant and grinding debris, has good screening and collection effects, and is relatively simple in structure, thereby improving the practicality of the centerless grinder."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During the use of the utility model, since the coolant will flow on the screen, the metal debris in the used coolant cannot pass through the screen and will remain on the screen. The screened coolant will flow into the collecting tank through the sleeve frame. The collecting tank will temporarily store the sleeve frame, and then the coolant will be re-injected into the top transfer box through the side liquid pump. However, in actual use, as the metal debris and coolant fall on the surface of the screen, the metal debris is likely to be stuck inside the screen, which affects the collection of the metal debris and has certain limitations. Therefore, it is necessary to improve an automatic centerless grinder to solve the above problems. Utility Model Content
