[0022] See also Figures 1 to 4 In an embodiment of the utility model, a hole measuring device for flange processing includes a transfer plate 1, which is relatively fixedly connected to the upper side of a driving structure 2, and a detection structure 3 is fixedly installed on one side edge of the driving structure 2. The driving structure 2 includes a base plate 201, and a motor 203 is fixedly installed on one side edge of the bottom of the base plate 201. The output end of the motor 203 passes through the base plate 201 and is fixedly installed with a support plate 204. A toggle rod 205 is fixedly installed on one side of the bottom of the support plate 204, and one end of the toggle rod 205 is slidably connected with a toggle groove 206, and the toggle groove 206 is provided at the four ends of a cross 207; four support columns 202 are fixedly installed at equal angles in a ring shape on the bottom side of the base plate 201, and the base plate 201 supports the overall structure.

[0023] Specifically, the abutment plate 204 is rotated by the No. 1 motor 203, and the abutment plate 204 drives the toggle rod 205 to rotate, and then the toggle rod 205 is inserted into the toggle slot 206 to rotate the cross 207. The toggle rod 205 rotates one circle, and the cross 207 rotates a quarter of a circle, thereby controlling the transfer plate 1 to rotate a quarter of a circle synchronously, so that the transfer plate 1 can stay for a period of time after moving the distance of a workstation, providing sufficient time for the detection structure 3 to perform aperture detection, and optimizing the flange aperture detection work from manual detection to assembly line-type automatic detection method, saving manpower and greatly improving work efficiency.
