Abstract

The invention discloses a screw grinding wheel modification method and its device in the technical field of grinding wheel modification. The modification method is as follows: first install the modification head and the handle, and then adjust the rotation according to the angle of the straight line profile of the screw rod. The angle of the outer shell relative to the shell, after the angle adjustment is completed, fix the rotating outer shell on the shell; install the shaping device on the machine tool workbench, and connect the rotating shaft that drives the shell to rotate with the rotary disk on the machine tool; Adjust the trimming head to the longest elongated position, and then set the tool; the grinding wheel rotates at high speed, controls the slow rotation of the rotary table on the machine tool, controls the movement of the worktable, controls the moving distance of the worktable according to the rotation angle of the rotary table, and controls the rotation of the rotary table Rotation angle, so that the two can realize the linkage that the rotating disk rotates one circle, and the machine table moves a screw lead; if the modification is completed, the other side of the grinding wheel is modified in the same way; otherwise, continue to modify one side of the grinding wheel ; The present invention is simple in shape modification and high in efficiency.

Description

technical field

[0001] The invention belongs to the technical field of screw forming, and in particular relates to a screw grinding wheel modification method and a device thereof. Background technique

[0002] As the core of screw profile grinding technology, grinding wheel modification directly affects the final tooth shape accuracy and surface quality of the screw. At present, for the modification of the grinding wheel for screw grinding, it is first necessary to analyze the positional relationship of the formed grinding wheel when grinding the helicoidal surface through the meshing principle, establish the mathematical model of the screw grinding process, and then derive the space contact line equation according to the tangent condition, after transformation Obtain the profile of the grinding wheel shaft section, and then modify the grinding wheel according to the profile of the grinding wheel shaft section, but it is difficult to calculate the sand profile, and the conta...

Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing.

[0022] A grinding wheel modification method for a screw, comprising the following steps:

[0023] (1) Install the shaping head 14 on the handle 8, the handle 8 is installed in the rotatable rotating outer body 5, and the handle 8 can be telescopically moved in the rotating outer body 5;

[0024] (2) According to the angle of the linear profile of the screw, adjust the angle of the rotating outer body 5 relative to the housing, and after the angle adjustment is completed, fix the rotating outer body 5 on the housing;

[0025] (3) Install the shaping device on the machine table, and connect the rotating shaft 2 that drives the housing to rotate with the rotating disk on the machine tool;

[0026] (4) Adjust the trimming head 14 to the longest elongation position, and align the telescopic movement direction of the gold trimming head with the rotation center of the grinding wh...
