[0002] Flanges, also known as flanged discs or flanges, are components that connect shafts and are used to connect pipe ends. Flanges are also used on equipment inlets and outlets, such as reducer flanges, to connect two pieces of equipment. Flange production requires drilling, which necessitates the use of flange drilling equipment.

[0003] After searching, the patent publication number CN209969649U discloses a convenient flange hole-making device, including a workbench and a drilling mechanism. The top of the workbench is slidably connected to a plurality of limit rods, and the longitudinal sections of the plurality of limit rods are all F-shaped structures. The bottoms of the plurality of limit rods are welded with nut sleeves. The outer ring of the workbench is provided with a plurality of drive motors, and the output shaft of the drive motor is connected to a screw, and the screw is connected to the nut sleeve. In the utility model, by driving the servo motor to rotate, the output shaft of the servo motor is connected to the first gear plate and meshed with the second gear plate, so that the second gear plate drives the coaxial roller to rotate, so that the roller drives the flange to rotate, and changes the position of the flange at the bottom of the drilling mechanism, that is, realizes the conversion of the flange drilling position. It only needs to accurately control the rotation angle through the servo motor, which is convenient and fast.

[0004] However, this patent still has some shortcomings. In actual use, this flange hole-opening device can only open one hole in the flange at a time. Since multiple mounting holes are usually required on the flange, multiple hole-opening operations are required to complete the processing of a flange. The operation steps are cumbersome and time-consuming, and it is not suitable for mass production of flanges. The flange processing efficiency is low.

[0005] To this end, we proposed a flange opening device. Utility Model Content
