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