Detailed Description
The invention is further described with reference to the following figures and specific embodiments.
As shown in fig. 1, the test fixture of the embodiment mainly comprises a connecting flange plate 1, an adapter cylinder 2, an adapter plate 3, a substrate 4 and a steel ball 5, wherein the connecting flange plate 1 is used for fixing the whole fixture on a 45-degree oblique rotating shaft of a five-axis machining center, and specifically, the connecting flange plate 1 can be fixed by 4 phi 8mm screws at a step position above the head of the 45-degree oblique rotating shaft. Two ends of the adapter cylinder 2 are respectively fixedly connected with the connecting flange 1 and the adapter plate 3. In this embodiment, for the convenience of processing, the adapter 2 is a sleeve with a circular cross section, and in other embodiments, the cross section may be a sleeve with a rectangular cross section or any other shape. The end face of the adapter cylinder 2 fixed with the adapter plate 3 is an inclined plane, after the adapter plate 3 is fixed, the included angle between the adapter plate 3 and the axial central line of the adapter cylinder 2 is 45 degrees, and the rotating shaft is inclined 45 degrees, so that the workload when the substrate 4 is parallel to the inclined shaft can be reduced, and the geometric center of the adapter plate 3 is positioned on the extension line of the axial central line of the adapter cylinder 2. In order to reduce the workload of adjusting the test element axis and the rotation axis inclined at 45 °, the circular adapter plate 3 is selected in this embodiment, and may be any shape such as rectangular or hexagonal in other embodiments.
The substrate 4 is fixed on the adapter plate 3 by using screws, and the regular polygon prism and the laser interferometer can be selected as the test element in the embodiment, so that the substrate 4 is provided with 4 special adapter holes 44 for matching with the laser interferometer roundness dividing device and 4 adapter holes 44 for matching with the regular polygon prism special tool, a spherical pit is arranged at the central position of the substrate 4, and the built-in steel ball 5 is used for adjusting the verticality error and is commonly called as the tower error, so that the substrate 4 can be ensured to be parallel to the rotation direction of the rotation shaft with the inclination angle of 45 degrees. A diameter aligning jackscrew 42 and a diameter aligning screw 41 are arranged along the radial direction of the outer edge of the substrate 4, the diameter aligning jackscrew 42 can adjust the test element to be concentric with the rotation center of a rotating shaft with an inclined angle of 45 degrees so as to reduce the measurement error, and the concentric adjustment can be realized by a meter making method. The inclination angle of the substrate 4 can be adjusted by the diameter aligning screws 41, so that the substrate 4 is ensured to be parallel to the adapter plate 3. After the installation is finished, a conventional testing method can be adopted to carry out precision detection and data acquisition on the rotating shaft with the angle of 45 degrees.
During specific testing, the method can be realized through the following processes:
the first step is as follows: and connecting the test tool with the position of the step above the spindle head of the rotating shaft inclined by 45 degrees.
The second step is that: the dial gauge is used for measuring the parallelism runout of the substrate 4 of the test tool and the rotation direction of the 45-degree inclined rotating shaft is not more than 0.01mm, the rotation range of the 45-degree inclined rotating shaft is-15 degrees to +180.5 degrees, if the two rotation directions are not parallel, the diameter aligning screw 41 is adjusted, and the substrate 4 and the adapter plate 3 are adjusted to be parallel by utilizing the arbitrary freedom degree adjusting characteristic of the steel ball 5, namely the substrate 4 is parallel to the rotation direction of the 45-degree inclined rotating shaft.
