Description

Technical Field

[0001] The invention relates to the technical field of grinding devices, in particular to a high-speed steel grinding device. Background Art

[0002] High-speed steel is a tool steel with high hardness, high wear resistance and high heat resistance. It is also called high-speed tool steel or sharp steel, commonly known as white steel. High-speed steel grinding is a process method that improves grinding efficiency and grinding quality by increasing the linear speed of the grinding wheel. It is usually used in the processing of high-speed steel materials.

[0003] For example, the Chinese patent authorization announcement number is CN217966207U, "A high-speed steel grinding device, the high-speed steel grinding device comprising: a workbench, one end of which is fixedly mounted with a first mounting block and a second mounting block, a grinding mechanism is mounted between the two first mounting blocks; a clamping mechanism, the clamping mechanism is rotatably connected between the two second mounting blocks";

[0004] In the above-mentioned comparative document, the arc-shaped side surface of the cylindrical high-speed steel is uniformly ground, and the high-speed steel can be clamped and fixed accordingly according to different lengths and different diameters.

In addition, when the grinding wheel is grinding, the grinding position of the grinding wheel is cooled by spraying water and the grinding debris is flushed. The debris is easy to adhere to the surface of the tool and the workpiece, and needs to be cleaned by external equipment, resulting in inconvenience in cleaning the high-speed steel after grinding.

[0030] In this embodiment, the grinding tool 6 includes an electric cylinder and a grinding tool head. The grinding tool head in the grinding tool 6 is fixed on the telescopic end of the electric cylinder, and the electric cylinder is fixed on the front side of the driving gear 91 on the front side of the servo motor 9.

[0031] In this example, the positioning plate 53 is driven to rotate by the output end of the adjusting motor 51 in the positioning seat 5, and the positioning rod 56 penetrating the front of the positioning plate 53 can expand and contract under the cooperation of the front guide groove of the positioning seat 5 and the positioning groove 55, so that high-speed steel with different diameters can be clamped and fixed on the front of the positioning seat 5;
