Grinding wheel slotting tool and slotting method

Abstract

The invention provides a grinding wheel slotting tool and a slotting method, and belongs to the field of machining. The grinding wheel slotting tool comprises grinding wheel dressers, a connecting block and disc milling cutter shanks; the disc milling cutter shanks are mounted on the connecting block and are arranged in the circumferential direction of the connecting block; and the grinding wheeldressers form a spiral mounting track along the circumferential direction of the connecting block and the orientations of the grinding wheel dressers are perpendicular to the tangential direction of the spiral track. According to the grinding wheel slotting tool and the slotting method, relying on that the grinding wheel dressers move relatively in a grinding wheel grinding area and cut the grinding wheel to form a grid of a circumferential surface structure of the grinding wheel, the grinding wheel dressers and a grinding wheel to be machined can rotate around the axes respectively and perform the movement of a worm and a gear that are engaged with each other; in an overlapped part of the grinding wheel dressers and the grinding wheel to be machined, the quick grinding wheel slotting toolcuts the grinding wheel to complete a slotting operation; the grinding wheel is slotted and grid grooves are formed in the circumferential direction of the grinding wheel; the defects of workpiece burning and thermal deformation caused by grinding in the prior art are overcome; the slotting quality is good; and the efficiency is high.

Description

technical field [0001] The invention relates to the field of machining, in particular to a grinding wheel grooving tool and a grooving method. Background technique [0002] Grinding is a cutting process in which the surface of a workpiece is machined with abrasive tools such as a high-speed rotating grinding wheel. It is a processing method commonly used in mechanical processing and has a very important position. Grinding is used to process special and complex shaped surfaces such as internal and external cylindrical surfaces, conical surfaces, planes, threads, gears and splines of various workpieces. Due to the high hardness of the abrasive grains and the self-sharpening of the abrasive tool, grinding can be used to process various materials, including hardened steel, high-strength alloy steel, hard alloy, glass, ceramics and marble and other high-hardness metals and non-metallic materials. metallic material. [0003] Grinding is mainly used for finishing, removing workp...

Problems solved by technology

However, due to the large number of grooves on the grinding wheel, the processing efficiency of the current method of cutting grooves on the grinding wheel with the help of laser is not optimistic.

[0005] Patent document CN208117609U discloses a diamond grinding wheel end face grooving device, including a fixed piece, a fixed block, a first hydraulic cylinder, a moving plate, a second hydraulic cylinder, a mounting plate, a first motor, an annular guide rail, a cutter, and a third hydraulic cylinder , reel, second motor, third motor, fan housing, fan body, dust box, fourth motor and connecting rod, use the different lifting heights of the four second hydraulic cylinders to adjust the inclination angle of the moving plate , so as to adjust the inclination angle of the diamond grinding wheel, use the second motor to drive the rotating shaft of the reel to rewind the steel wire cable, thereby controlling the rise of the fan housing, moving the material guide pipe out of the dust box, and removing the dust inside the dust box The waste is disposed of, but the device has a lot of equipment and a complicated structure
