It is worth noting that the first groove 12 and the second groove 13 are respectively arranged on adjacent corners, and the optical engine mounting seat 2 can be limited from moving on the xy plane by the first groove 12 and the second groove 13. For example, when the second groove 13 is parallel to the x-axis and is used for limiting the movement of the ball screw in the y-axis direction, the straight line formed by the first groove 12 and the second groove 13 is located on the x-axis, and since the ball screw on the second groove 13 is limited to move in the y-direction, the second groove 13 cannot rotate around the first groove 12, that is, the optical engine mounting base 2 cannot be displaced on the xy-plane by the matching of the first groove 12 and the second groove 13.
It can be understood that, since the first groove 12 limits the degree of freedom of the ball screw in both directions of the x-axis and the y-axis, the second groove 13 limits the degree of freedom of the ball screw in one direction of the x-axis or the y-axis, and the third groove 14 does not limit the degree of freedom of the ball screw, during adjustment, the ball screw corresponding to the first groove 12 can only be adjusted in the z-axis, and the ball screw corresponding to the second groove 13 can only be adjusted in the z-axis and the (Rx or Ry) direction, and the ball screw corresponding to the third groove 14 can be adjusted in three directions of the z-axis, Rx and Ry, and the relative arrangement of the first groove 12, the second groove 13, and the third groove 14 can enable the ball screws corresponding to the first groove 12 and the second groove 13 to be relatively limited without following the adjustment amount when the position of the optical engine mounting base 2 is adjusted by the ball screw corresponding to the third groove 14, the embarrassing situation that the optical machine mounting seat 2 cannot be adjusted to a proper position finally due to the fact that other ball screws are adjusted along with changes when one ball screw is adjusted is avoided. It is noted that the ball screws need to be in sufficient contact with the groove surfaces of the first, second and third grooves 12, 13, 14 to ensure that there is no random variation between the camera mount 2 and the leveling base 1 during leveling.
Specifically, in the embodiment of the present invention, three sets of ball screws may be used for adjustment, that is, only one of each of the first groove 12, the second groove 13, and the third groove 14 is provided; one first groove 12, one second groove 13 and two third grooves 14 may also be symmetrically disposed on four corners of the leveling base 1, that is, four groups of ball screws are disposed on the four corners of the leveling base 1 for adjustment, so that the adjustment stability is higher.
