Problems solved by technology

[0002] Cams are widely used in various internal combustion engines, and their precision grinding has always been a difficult problem in the machine tool industry. The main reason is that the cams have complex shapes. The radius of curvature of the groove part is relatively small, and the diameter of the grinding wheel required to grind the groove part is also relatively small, so the speed of the grinding wheel must be increased under the requirement of constant linear speed, and the diameter of the motor spindle that drives the grinding wheel to rotate must also be reduced accordingly. It brings great limitations to the design and application of machine tools

Embodiment Construction

[0009] Such as figure 1 As shown, a grinding method for a concave surface with a concave-convex wheel, the rotation center line 2 of the grinding wheel 1 is set perpendicular to the rotation center line 4 of the cam 3, and the grinding wheel spindle is installed on the same side as the cam rotation center line and the grinding wheel rotation center. Lines are respectively perpendicular to the linear motion guide rail 5, moving the linear motion guide rail 5 to control the distance between the center of the grinding wheel and the center of the cam, and rotating the cam accordingly, the concave surface of the cam can be processed.

[0010] In the present invention, the cross section of the grinding wheel can be trimmed to be consistent with the shape of the cylindrical tappet and the relative position of the cam center. As long as the cam is rotated and the grinding wheel is moved to make the motion relationship between the two conform to the cam rotation angle-cylindrical tappet...

Abstract

The invention belongs to the class of a mechanical processing method, in particular to a method for grinding a concave surface of a cam with a concave surface. The method is characterized in that a rotating center line of a grinding wheel is set to be perpendicular with a rotating center line of a cam, a main shaft of the grinding wheel is arranged on a linear motion guide rail which is respectively perpendicular with the rotating center line of the cam and the rotating center line of the grinding wheel, the linear motion guide rail is moved to control the distance between the center of the grinding wheel and the center of the cam, and the concave surface of the cam can be processed by correspondingly rotating the cam. The cross section of the grinding wheel can be trimmed into arbitrary shape and curvature radius according to requirements without influencing the diameter of the grinding wheel, and the motion linear speed of the grinding wheel can be ensured with the grinding wheel with large diameter. The method is simple, convenient, scientific and reasonable and has high grinding accuracy.
