Flanges are widely used in mechanical fields such as automotive parts and pipeline transportation. In the drilling process of flange processing, a drilling device is required for hole processing.

[0003] For example, a flange drilling device with the publication (announcement) number CN112475370A includes: a frame; a sliding plate, slidably connected to the frame for support and installation; a rotating mechanism, rotatably connected to the sliding plate; a stepping motor, fixedly installed on the sliding plate, for driving the rotating mechanism to rotate; a clamping mechanism, slidably connected to at least one side of the rotating mechanism, for fixing flanges of different specifications; a first driving motor, fixedly installed in the rotating mechanism, for driving the clamping mechanism to clamp the flange; a lifting mechanism, installed on the frame for adjusting the processing stroke; a second driving motor, fixedly installed on the frame, for driving the lifting mechanism to lift and lower; a drilling mechanism, installed on the lifting mechanism, and performing lifting and lowering movements with the lifting mechanism; a third driving motor, fixedly installed on the lifting mechanism, for driving the drilling mechanism to drill holes. However, since the drill bit in the drilling mechanism is not restricted, when drilling holes in the flange, the drilling verticality and aperture accuracy of the drill bit may deviate, affecting the flange drilling processing quality.

[0004] Therefore, a flange drilling device that is easy to correct and can limit and correct the drill bit to ensure the verticality of the drilled hole and the accuracy of the hole diameter has been developed. Utility Model Content

[0011] In a preferred embodiment of the utility model, it also includes a limiting mechanism, which includes a connecting bracket, a limiting frame and a torsion spring. The connecting bracket is connected to the upper rear side of the workbench, and the limiting frame is rotatably connected to the connecting bracket. The limiting frame is located outside the drill bit, and a torsion spring is connected between the limiting frame and the connecting bracket.

[0012] Compared with the prior art, the utility model has the following advantages: 1.

The first spring 62 is connected between the movable column 61 and the fixed column 60. The rotating locking column 63 is rotatably connected to the upper side of the fixed column 60. The rotating locking column 63 contacts the movable column 61. Eight fixed connecting frames 64 are connected to the upper side of the rotating connecting disk 3. The fixed connecting frames 64 are all slidably connected to the locking guide frames 65. The locking guide frames 65 are all provided with cushions to avoid wear of the flange.
