The invention provides a method for measuring a slant wall thickness of a hub. Specifically, the hub is laid flatwise on a detection platform of a three-coordinate measuring machine; afterwards, a first inner wall point 1 and a second inner wall point 2 are sampled from an inner rim slant of the hub
The invention provides a method for measuring a slant wall thickness of a hub. Specifically, the hub is laid flatwise on a detection platform of a three-coordinate measuring machine; afterwards, a first inner wall point 1 and a second inner wall point 2 are sampled from an inner rim slant of the hub along a YZ axial section of the three-coordinate measuring machine, and X-axis coordinate values of the two points are set to zero to establish a first Cartesian coordinate system; the two points defined in step 101 are connected and configured into an axial line of a rim wall thickness; a second Cartesian coordinate system is established with a direction of the axial line of the rim wall thickness as a Y′ axis; an inner rim wall thickness point 3 from an inner rim wall, and an outer rim wall thickness point 4, both having X′ values of zero, are sampled; a two-dimensional distance between the inner rim wall thickness point 3 and the outer rim wall thickness point 4 in a Z′ axis is calculated under the second coordinate system and recorded as a measured slant wall thickness value of the hub. The method provided by the present invention has the advantages of avoiding the situation that the three-coordinate measuring machine has a large error in measuring a rim wall thickness due to the use of the detection platform as a benchmark, improving the accuracy of detection, and providing the basis of automated rim thickness detection.

1. A method for measuring a slant wall thickness of a hub, characterized in that, the method comprises a step 101, flatwise laying the hub on a detection platform of a three-coordinate measuring machine, orderly sampling two points, which are named as a first inner wall point (1) and a second inner wall point (2), from an inner rim slant of the hub along a YZ axial section of the three-coordinate measuring machine, and setting X-axis coordinate values of the two points to zero, thus establishing a first coordinate system, namely a Cartesian coordinate system; a step 111, connecting and configuring the first inner wall point (1) and the second inner wall point (2) defined in the step 101 into a three-dimensional straight line, which is named as an axial line of a rim wall thickness; a step 121, establishing a second coordinate system, namely a Cartesian coordinate system, with a direction of the axial line of the rim wall thickness as a Y′ axis; a step 131, sampling an inner rim wall thickness point (3) from an inner rim wall and an outer rim wall thickness point (4) from an outer rim wall, and setting X′ values of the inner and outer rim wall thickness points to zero; and a step 141, calculating a two-dimensional distance between the inner rim wall thickness point (3) and the outer rim wall thickness point (4) in a Z′ axis under the second coordinate system and recording the distance as a measured slant wall thickness value of the hub. 2. The method according to claim 1, characterized in that, further comprising a step 122 between the step 121 and the step 131: regulating the coordinate system back to the second coordinate system after other measurement and coordinate system regulation take place after the step 121. 3. The method according to claim 1, characterized in that, in the step 131, a direction of sampling the inner rim wall thickness point (3) and the outer rim wall thickness point (4) is a direction along the Z′ axis under the second coordinate system.
