Description

Technical Field

[0001] The invention relates to the technical field of drilling devices, in particular to a rotary drilling device for gas turbine flange parts. Background Art

[0002] A drilling machine is a general term for machinery and equipment that uses a tool that is harder and sharper than the target object to leave a cylindrical hole or hole on the target object through rotary cutting or rotary extrusion. It is also called a drilling machine, a punching machine, a hole-drilling machine, a through-hole machine, etc. It achieves the desired effect by drilling holes in precision parts. There are semi-automatic drilling machines and fully automatic drilling machines. With the increase in human resource costs, most companies consider fully automatic drilling machines as their development direction.

[0003] In the prior art, a Chinese patent with publication number "CN112475370A" discloses a flange drilling device, which places a flange to be processed on a clamping mechanism, energizes a first drive motor and controls the steering, and then the first drive motor drives the clamping mechanism to clamp the flange and then cuts off the power; then, the angle between the pre-processed holes and the holes on the flange is calculated according to the specifications of the flange to be processed, and the relative position of the sliding plate is adjusted and fixed, which solves the problem that some existing drilling equipment needs to reposition the drilling position each time when drilling a flange.

[0004] In the drilling process of gas turbine flange processing, a drilling device is required to perform hole processing. In the process of the drilling device processing the flange, a clamping mechanism is required to fix the flange. Most of the current methods use two clamping plates to fix the flange from the outside, or fix it from the inside. However, when the flange is large or heavy, simply two clamping points may not be enough to prevent the flange from slight displacement or shaking during the drilling process, resulting in inaccurate drilling. Especially when the shape, material and thickness of the flange are uneven, the two clamping plates may not be able to evenly distribute the clamping force, affecting the drilling accuracy.

When the stabilizing rod 43 contacts the upper end surface of the placement plate 3, the stabilizing rod 43 will be fixed to the inner side of the flange through the positioning of the rotating shaft 42 and the torsion force of the torsion spring 44 through the continuous descent of the connecting frame plate 38. When the second electric push rod 36 drives the drill rod 37 to drill the flange, the cross plate 39 will squeeze the compression spring 48 on the connecting frame plate 38, and the stabilizing rod 43 will change its angle at the same time.
