Abstract

The invention relates to a displacement analog loading device of a form grinding wheel gear grinding machine, comprising a loaded test piece and a loading assembly, wherein the loaded test piece is arranged on the form grinding wheel gear grinding machine, and the loading assembly is used for analog loading; the form grinding wheel gear grinding machine has the functions of rectilinear motion on an X axis, forward and backward rectilinear motion on a Y axis, rectilinear motion on a Z axis, n rotary motion around the Y axis, C rotary motion around the Z axis and A rotary motion around the X axis; and an included angle alpha is formed between the axial lead of a ball seat of the loading assembly and the X axis direction of a Y axis assembly, and the included angle between the normal of the loaded surface and the X direction of a machine tool coordinate system is alpha. The method for detecting rigidity distribution in the invention comprises the following steps of: moving the loading assembly to a loading position for loading by using the matched motions of the Z axis, the Y axis and the X axis; detecting the displacement by using a displacement sensor, detecting an analog load by using a force sensor, and then calculating the rigidity of the loading position under the analog load; and changing the loading position and repeating the process to obtain the rigidity distribution under the analog load. The device and the method in the invention realize the detection of the static rigidity distribution.

Description

Technical field [0001] The present invention is a mechanical detection technology field. It belongs to the different positions of processing operations to simulate the static rigidity detection technology of the CNC machine tool under the condition of simulation and loading conditions.The static rigid distribution detection method of the dental deformation is simulated. Background technique [0002] In the processing space of the machine tool, with the change of the position of the processing point, the loading position and load (load include force and torque) of the machine tool component change, and the static rigidity of the machine tool changes.The static rigid changes in different processing positions can be described by the stiffness distribution. The size and static stiffness distribution of the static stiffness directly affects the processing accuracy and affects the vibration characteristics of the machine tool. [0003] The surface of the workpiece processing is formed ...
