specific Embodiment approach 1

[0043] Specific implementation mode one: combine figure 2 and image 3 Describe this specific embodiment, a method for measuring the waveform size of the three-lobe wave outer raceway of a bearing in this specific embodiment, the method is realized by the following steps,

[0044] Step 1. Selection of CMM:

[0045] The reference600 high-precision three-coordinate measuring instrument is selected for measurement, and according to the measurement requirements of the three-lobe outer raceway, the measurement of the waveform size of the three-lobe outer raceway bearing is realized through programming;

[0046] Step 2. Selection of measuring probes:

[0047] Use reference probes and non-reference probes for measurement. Non-reference probes include vertical probes and disc probes. The vertical probes are used to measure the three-lobe wave outer circle reference: end face, outer diameter, end face narrow convex Platform measurement, the disc probe is used to measure the three-l...

specific Embodiment approach 2

[0063] Embodiment 2: The maximum allowable error of the reference600 high-precision three-coordinate measuring instrument in step 1 of this embodiment is E=(1.0+L / 350) μm. Such setting ensures the measurement accuracy of the waveform size of the three-lobed outer raceway of the bearing. Other compositions and connections are the same as in the first embodiment.

[0064] The reference600 high-precision three-coordinate measuring instrument of this embodiment is the reference600 high-precision three-coordinate measuring instrument of the German company Leitz.

specific Embodiment approach 3

[0065] Embodiment 3: The reference probe in step 2 of this embodiment is a φ5mm probe. Other compositions and connections are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention provides a method for measuring the waveform size of a bearing three-lobed wave outer raceway, and relates to the technical field of geometric quantity measurement and dimension measurement. The method solves the problem that according to an existing three-lobed wave outer raceway, the waveform size of the bearing three-lobed wave outer raceway during the machining process cannot bemeasured. The method comprises the following steps of step one, selecting reference 600 high-precision three-coordinate for measuring; step two, using a reference probe, and selecting a vertical probeand a disc-shaped probe as non-reference probes for measurement; step three, selecting a magnetic suction cup to clamp a workpiece; step 4, verifying the measurement probe; step 5, roughly constructing a coordinate system; step 6, finely constructing the coordinate system for the first time; step 7, finely constructing the coordinate system for the second time; step 8, using a disc probe to scanmeasurement; step 9, converting actual waveform data to a polar coordinate system for outputting 360 point data; step 10, finding the highest and lowest points of the waveform. The method is used formeasuring the waveform size of the bearing three-lobed wave outer raceway.

Description

technical field [0001] The invention relates to the technical fields of geometric quantity measurement and dimension measurement, in particular to a method for measuring the waveform dimension of a three-lobed outer raceway of a bearing. Background technique [0002] The geometric shape of the three-lobe waveform refers to the displacement of the raceway contour line offset from the base circle. The raceway base circle refers to the circle formed by the three high points and the three low points of the waveform of the three-lobe wave raceway. middle circle. The waveform profile is divided into three preload areas distributed uniformly at 120°, the three points of 0°, 120°, and 240° are the highest points of the three-lobe wave protruding outward along the base circle; the three points of 60°, 180°, and 300° The point is the lowest point where the three-lobe wave is recessed inward along the base circle, and the raceway profile of the three-lobe wave is as follows: figure 1...
