Online automatic dressing device for high-precision CBN grinding wheel

Abstract

The invention provides an online automatic dressing device for a high-precision CBN grinding wheel. The device comprises a machine tool platform, wherein a base is arranged on the machine tool platform, a cross-shaped sliding table is arranged below the base and connected with the machine tool platform in a sliding mode, a grinding wheel electric spindle is arranged on the base and used for installing a grinding wheel to be dressed, a first grinding dressing device used for dressing an outer contour of the grinding wheel is arranged above the grinding wheel electric spindle, the first grindingdressing device is connected with the base in a sliding mode, a second grinding dressing device used for dressing an outer end face of the grinding wheel is arranged on one side of the cross-shaped sliding table, and the second grinding dressing device is perpendicularly fixed to the machine tool platform and located at a front end of the grinding wheel electric spindle. The CBN grinding wheel dressing device is advantaged in that the double-cross-shaped sliding mechanism is used for controlling dressing movement of the CBN grinding wheel, dressing of the outer contour and the outer end faceof the CBN grinding wheel can be achieved at the same time and can be conducted synchronously, the grinding wheel dressing speed is increased, the time needed by production is shortened, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of grinding wheel dressing devices, in particular to a high-precision online automatic dressing device for CBN grinding wheels. Background technique [0002] CBN grinding wheels are often used in form grinding. Due to the different shapes of various parts processed by form grinding, and in recent years, the processed parts have trends such as small batches, complex shapes, high requirements for shape and position accuracy, and short production cycles. Traditional grinding machines The sand repairing device is still in the stage of manual sand repairing, and the grinding wheel needs to be disassembled and reinstalled for repairing. Moreover, the traditional grinding wheel drive of the grinding machine uses an ordinary four-phase motor, and the spindle structure is relatively complicated, and there is slight vibration, which will affect the processing. Quality, the dressing of different positions of the grindi...

[0002] CBN grinding wheels are often used in form grinding. Due to the different shapes of various parts processed by form grinding, and in recent years, the processed parts have trends such as small batches, complex shapes, high requirements for shape and position accuracy, and short production cycles. Traditional grinding machines The sand repairing device is still in the stage of manual sand repairing, and the grinding wheel needs to be disassembled and reinstalled for repairing. Moreover, the traditional grinding wheel drive of the grinding machine uses an ordinary four-phase motor, and the spindle structure is relatively complicated, and there is slight vibration, which will affect the processing. Quality, the dressing of different positions of the grinding wheel needs to be changed many times, not only requires multiple staff to operate, the work intensity is high, the product processing cycle is long, the work efficiency is low, and it needs to invest in multiple equipment for processing, the production cost is high
