Description

Technical Field

[0001] The utility model relates to the technical field of centerless grinders, in particular to a feeder for a 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 except for stopping grinding, the principles are the same. A centerless grinder requires a feeding mechanism when processing metal pipes.

[0003] Patent No. CN202320264425.8 discloses a feeding mechanism for a centerless grinder, which relates to the technical field of centerless grinders, including a workbench, a bottom plate and a transmission mechanism are fixedly installed on the top of the workbench, a feeding mechanism is fixedly installed on the top of the bottom plate, the feeding mechanism includes two support blocks, springs are fixedly installed on the tops of the two support blocks, lining plates are fixedly installed on the tops of the two springs, a material box is fixedly installed between the opposite sides of the two lining plates, and a rectangular plate is fixedly installed on the bottom of the material box;

[0004] Although the above patent can change the size of the discharge end according to the model of the grinding piece during use, by starting the electric telescopic rod, the position of the limit plate can be changed, so that the distance between the grinding piece and the grinding piece can be changed according to the model of the grinding piece, so that the grinding piece can be accurately pushed into the centerless grinder, which increases the practicality and reliability of the device. However, in the actual adjustment process, it can only be adjusted according to the outer diameter of the grinding piece, and cannot be adjusted according to its length, which leads to certain limitations. It can only be applicable to grinding pieces of the same length but different outer diameters, resulting in low applicability of the device and poor feeding effect of the device. Therefore, a centerless grinder feeder is urgently needed to solve the above problems. Utility Model Content
