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 shaping head 14 to the longest extension position, align the telescopic movement direction of the diamond practice pen with the rotation center of the grinding wheel ...

Abstract

The invention discloses a grinding wheel dressing method and device of a screw in the technical field of grinding wheel dressing. The dressing method comprises the steps that firstly, a dressing headand a cutter handle are installed, then the angle of a rotary outer sleeve with respect to a housing is adjusted according to the angle of linear outline of the screw, and the rotary outer sleeve is fixed to the housing after angle adjustment; the dressing device is installed on machine tool worktable, a rotary shaft driving the housing to rotate is connected with a rotating disc on a machine tool; the dressing head is adjusted to the longest extending position, and then tool alignment is performed; a grinding wheel rotates at high speed, the rotating disc on the machine tool is controlled torotate slowly, movement of the worktable is controlled, the movement distance of the worktable is controlled according to the rotary angle of the rotating disc, the rotation angle of the rotating discis controlled to achieve one-circle rotation of the rotating disc, the machine tool worktable moves for linkage of a screw stroke; if dressing is completed, the other side of the grinding wheel is dressed with the same method; if not, dressing of one side of the grinding wheel continues. The grinding wheel dressing method is simple in dressing 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...
