Problems solved by technology

[0006] Using this method to adjust the radius of curvature (R) of the channel requires an experienced operator to complete it in a short time, but there is no guarantee that it can be accurately adjusted to the requirements of the process at one time.
Moreover, this method is very dangerous, it is easy to scratch the hands, causing accidents, and the error is large, it is difficult to master, and it is labor-intensive and time-consuming.

Embodiment 1

[0047] The following takes 3MZ1420 as an example to explain how to adjust the position of the diamond pen.

[0048] a. Dressing wheel. Make the diamond nib come into contact with the working surface of the grinding wheel.

[0049] b. Return the handle wheel dial to zero. The dresser is raised and the grinding wheel stops rotating.

[0050] c. Calculate the difference S between the workpiece radius and the dresser radius.

[0051] The 6315 outer ring of the ferrule is over, and the next variety is the 6317 outer ring. The nominal size of the radius of curvature of the 6315 channel is 14.17mm, and the nominal size of the radius of curvature of the 6317 channel is 15.84mm.

[0052] According to the formula: S=(R1-R)×100

[0053] Because 14.17 is the nominal size of the dresser radius, and 15.84 is the nominal size of the workpiece radius.

[0054] So S=(15.84-14.17)×100=167 (Simi)

[0055] d. If the S value is positive, turn the hand wheel clockwise to the position of 167 ...

Embodiment 2

[0062] The radius adjustment method of Shanghai Laibite CNC machine tool is the same as that of Embodiment 1, but the calculation formula is different:

[0063] 1. The manual feed value of the operation panel of the CNC machine tool is the same as the displacement of the workpiece feed table of the machine tool. The resulting value is directly added or subtracted from the machine origin. The origin position of the operation panel is in mm. Its formula is: S=R1-R.

[0064] 3MZ1430D processing of 6322 outer ring has been completed, and 6320 outer ring needs to be replaced. The nominal size of the radius of 6322 is 21.67mm, and the nominal size of the radius of 6320 is 19.17mm, according to the formula:

[0065] S=R1-R=19.17-21.67=-2.5(mm)

[0066] If the original position of the operation panel is 50.765mm after dressing the grinding wheel of 3MZ1430D, then 50.765-2.5=48.265(mm), manually retract the workbench to the position of 48.265mm, and use the same method to align the...

Abstract

The adjust method for cut grinding curvature radius of bearing ring channel belongs to bearing manufacture technique field. Wherein, the arc finisher connects to feeding platform; when rotating the handwheel, the said platform moves fore-and-aft, so does the finisher; by calculating with formula, it can adjust the said curvature precisely just one time. This invention has high precision and speed, and ensures quality and security, fit to wide range, and easy to master.

Description

technical field [0001] The invention belongs to the technical field of groove processing of bearing rings. Background technique [0002] Deep groove ball bearings have a smaller friction coefficient than other bearings when they move, so they have less friction resistance during use and have higher flexibility. The key reason is the steel ball. Because the groove of the ferrule is a circular arc working surface, it is also the track for the rolling of steel balls, so the processing quality of the groove will directly affect the working performance and life of the bearing. During channel processing, how to quickly and accurately determine the adjustment position of the grinding wheel dresser (R), the position of the dresser diamond will affect the processing quality of the channel curvature radius (R). [0003] During the process of grinding the groove of the bearing ring, the groove grinder often needs to change the type, and the curvature radius (R) of the ring groove of e...
