Embodiment

[0063] see figure 1 , a quasi-measurement center path planning implementation device for complex parts based on three-axis linkage, including a manually-controlled measuring column that can move along the Y-axis, and a measuring column that is controlled by a servo drive system and can move along the X, Z axis. The probe that moves in the axial direction also includes a spindle rotary shaft system that can rotate along the W-axis direction. The distance between the probe and the center of the spindle rotation axis system along the Y-axis can be displayed in real time through the computer.

[0064] The device also includes a base, a workpiece column for clamping the workpiece, and a drive control assembly (a computer and three grating rulers 11 corresponding to the X, Y, and Z axes).

[0065] The probe is a TESA inductive probe.

[0066] Taking the non-eccentric gear measurement process as an example, after inputting the parameters of the measured gear into the computer, the ...

Abstract

The invention provides a three-axis linkage-based complicated part accurate measurement central path planning realizing method and a device. the device comprises a base, a workpiece vertical column, and a measurement vertical column, wherein the measurement vertical column is provided with an electric sensing head capable of moving vertically and horizontally. Horizontal movement of the measurement vertical column is used for contotrlling the distance between the measuring head and the center of a spindle rotating shaft system, stepless adjustment of a basic circle can be realized, a series of basic circle discs do not need to assist measurement of a gear, the detection process is simplified, and detection errors due to wear of the basic circle discs can be solved. Through controlling vertical movement, horizontal movement of the measuring head and linkage of the spindle rotating shaft system, control of the measuring trajectory of the measuring head can be realized respectively, and helix, tooth profile and pitch error of the gear with any base circle radius value within the measuring range can be fully automatically measured. In addition, path planning of an eccentric gear can be realized, and full-automatic measurement on helix, tooth profile and pitch error of the eccentric gear can be realized.

Description

technical field [0001] The invention belongs to the field of precise measurement of complex profile lines, and in particular relates to a method and a device for realizing quasi-measurement center path planning of complex parts based on three-axis linkage. Background technique [0002] With the development of the machinery manufacturing industry, especially with the rapid development of the automobile industry and the wind power generation industry, the demand for gears is increasing, and the machining accuracy of the gears has an important impact on the quality of mechanical products. The transmission of mechanical equipment is unstable, which in turn causes aggravation of vibration and noise, which seriously affects the health of operators and greatly shortens the life of mechanical equipment. In order to improve the operating comfort of the product and improve the life of the product, the requirements for the quality of gear processing are getting higher and higher, which...
