Grinding wheel dressing method used for slewing support roller path grinding

Abstract

The invention relates to a processing method used for dressing a grinding wheel, in particular to a grinding wheel dressing method used for slewing support double circular roller path grinding, relating to the field of metal processing. In the dressing method, the rotation motion of the grinding wheel is taken as the main motion to form a principle axis S axis; the horizontal and vertical feeding linear motion of the grinding wheel is driven by the horizontal motion mechanism and the vertical motion mechanism of the grinding wheel to substitute the circular interpolating motion of the grinding wheel to form an X axis and a Z axis; the rotation of the diamond pen is driven by the diamond pen rotation motion mechanism to form a C axis; and the dressing of the whole grinding wheel is realized through the micro-segment dressing of the processing station after discretization, thus being capable of meeting the requirements of multispecies standard grinding wheel dressing functions and having the advantages of stable processing and stable accuracy; in the method, a macro instruction programming method is applied, and is a program compiling mode in which variables can be used for arithmetic operation, logic operation and function mixed operation, thus greatly simplifying program quantity and strengthening the processing and adaptive capabilities of the machine tool.

Description

technical field [0001] The invention relates to a processing method for grinding wheel dressing, in particular to a grinding wheel dressing method for grinding raceways of slewing bearings, the method mainly uses diamond pens to grind double-arc raceways of slewing bearings , involving the field of metal processing. Background technique [0002] As the market demand for slewing bearings continues to grow, advanced manufacturing equipment gradually replaces traditional equipment and improves the original production efficiency. At present, the grinding of the raceway is mainly through the trimmed grinding wheel for form grinding, so the precision of the dressing of the grinding wheel will directly affect the processing quality of the raceway. Three methods are generally used for grinding wheel dressing: manual diamond pen dressing method, forming diamond wheel dressing method by grinding, and numerical control program interpolation dressing method. The processing accuracy of...

Problems solved by technology

If the automatic programming processing method is used, different types of products must be reprogrammed, which prolongs the product development cycle and increases the development cost; and the program realized by automatic programming is huge, and it is difficult to find out the crux of the problem; The tool path, cutting speed, and grinding width have great randomness, and these parameters are required in actual processing, otherwise it is easy to make the cutting of the grinding wheel unstable during the processing, and the accuracy is different, thus affecting the processing accuracy of the workpiece and surface quality, even making the processing impossible
