Embodiment Construction

[0008] The present invention will be described in further detail below. see figure 1 , 2 , a cursor square axis for detection, including a disc 2 and a positioning shaft 3, the upper end of the positioning shaft 3 is coaxially connected with the lower surface of the disc 2, and is characterized in that: there is a cuboid 1 with a square cross section, The four rectangular sides of cuboid 1 are respectively the first side, the second side, the third side and the fourth side, the first side is opposite to the third side, the second side is opposite to the fourth side, and the first side is opposite to the third side. There are two through holes arranged up and down on the side, the first through hole 4 is located below, and the second through hole 5 is located above. The axes of the first through hole 4 and the second through hole 5 are parallel to each other and parallel to the disk. The lower surface 10 of the 2 is parallel, the axis of the positioning shaft 3 is located in ...

Abstract

The invention belongs to the field of airplane assembling and relates to a cursor square shaft for detecting a three-dimensional coordinate of an airplane tool positioning hole. The cursor square shaft is characterized by being provided with a cuboid [1] with a squared cross section, wherein four rectangular side faces of the cuboid [1] are respectively provided with two through holes which are arrayed from top to bottom; and a central hole [8] is arranged on an upper surface [9] of the cuboid [1]. The cursor square shaft disclosed by the invention can accurately detect the three-dimensional coordinates of central points at two ends in an axial direction of the positioning hole, so as to improve the mounting precision.

Description

technical field [0001] The invention belongs to aircraft assembly technology. The invention relates to a cursor square axis used for three-dimensional coordinate detection of positioning holes of aircraft tooling. Background technique [0002] The original cursor ball for detecting the positioning hole of the aircraft tooling can only detect the coordinate value of the center point at one end of the positioning hole on the part. In actual work, when some positioning hole positions are detected, it is necessary to simultaneously detect the three-dimensional coordinates of the center points of the two ends of the axis of the positioning hole. The existing cursor ball cannot accurately detect the three-dimensional coordinates of the center points of the two ends of the axis of the positioning hole, which affects the installation accuracy. Contents of the invention [0003] The purpose of the present invention is to provide a cursor square axis capable of accurately detectin...
