Embodiment Construction

[0047] Below in conjunction with accompanying drawing, technical content of the present invention is described:

[0048] Such as figure 1Shown is a typical slewing bearing, mainly including outer ring 1, inner ring 2 and steel ball 3. Among them, the raceway of the outer ring 1 that provides the movement of the steel ball 3 includes the upper busbar 10 of the inner raceway, the oil groove A11, and the lower busbar 12 of the inner raceway, and the raceway of the inner ring 2 that provides the movement of the steel ball 3 includes the upper busbar of the outer raceway 20 and the oil groove B21, outer raceway lower bus bar 22. According to the basic concept of four-point contact, points A, B, C, and D are the circle centers of the inner raceway upper busbar 10, the inner raceway lower busbar 12, the outer raceway lower busbar 22 and the outer raceway upper busbar 20, while E and F , G, and H are the contact points between the steel ball busbar 30 and the upper busbar 10 of the ...

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...
