Embodiment
The invention provides a kind of novel test apparatus auxiliary installing device, three pickup wires can be concentrated and fixed, can when hub moves, make line remain simultaneously and point to same point.
Fig. 1 illustrates concentric hub according to an embodiment of the invention.Fig. 2 (A)-2 (I) illustrates each view of this concentric hub.With reference to figure 1 and Fig. 2 (A)-2 (I), this concentric hub comprises mounting hole 7, mounting groove 8, arc-shaped guide rail 3, hemispherical groove 6, directions X pickup wire 4, Y-direction pickup wire 5, Z direction sensor line 1.This mounting groove 8 is connected with mounting hole 7.Arc-shaped guide rail 3 is in X-Y plane.Directions X pickup wire 4 couples with directions X sensor, and Y-direction pickup wire 5 couples with Y-direction pickup wire, and Z direction sensor line 1 couples with Z direction sensor.Described in the installation ball warp of directions X sensor and Y-direction sensor, mounting hole 7 and described mounting groove 8 are installed on described arc-shaped guide rail 3.This directions X sensor and this Y-direction sensor all point to the center of circle of arc-shaped guide rail 3 place circles.The centre of sphere of this hemispherical groove 6 is positioned at the center of circle of arc-shaped guide rail 3 place circles.This hemispherical groove 6 is for placing the installation ball of Z direction sensor.In one embodiment, the installation ball warp of described Z direction sensor packs described hemispherical groove into by described mounting hole.
Particularly, a reliable bead of end points processing of three pickup wires, on hub, there is an arc-shaped guide rail 3 in X-Y plane with one heart, when being arranged on the hub motion of point position, bead can slide along arc-shaped guide rail 3, realized two pickup wires (being directions X pickup wire 4 and Y-direction pickup wire 5) under motion conditions and still pointed to same point, be i.e. the center of circle of arc-shaped guide rail place circle.
In arc-shaped guide rail 3 centers, there is one and take hemispherical groove 6(that arc-shaped guide rail 3 centers are the centre of sphere as shown in Figure 2), can put the Z direction sensor installation bead of (being connected with Z direction sensor line 1), while being arranged on like this hub motion of point position, installation of sensors ball 2 rotates in any case, it is constant that the centre of sphere all remains at guideway centreline place, the unified constant function of measuring point while having realized test.
The installation and application of hub is as follows with one heart.In use, first, the threaded mounting hole 9 of hub rotates to above measuring point bolt with one heart, then directions X sensor is installed on arc-shaped guide rail 3 via mounting hole 7 and mounting groove 8, and by identical method, pack Y-direction sensor into arc-shaped guide rail 3, by mounting hole 7, pack the installation ball warp of Z direction sensor into hemispherical groove 6, installation again.In use, directions X sensor, Y-direction sensor can be free to slide on arc-shaped slide rail, Z direction sensor also can freely rotate the hemispherical groove 6 of self installing is interior, realize three sensors and point to all the time same point, be the centre of sphere of hemispherical groove 6, the center of circle of arc-shaped guide rail 3 namely.
