Abstract
The utility model is related to a kind of wind power flange inner wall auxiliary drilling tool, including main body, the main body is welded by inverted concave panel, support plate, bottom plate, backboard, and a center line is carved among the inverted concave panel；Support plate one end is connected to inverted concave upper panel, and the other end is connected on bottom plate；Bottom plate one end is vertical and is welded on inverted concave panel, and the other end is vertical and is welded on backboard.The auxiliary drilling tool cleverly changes the operative orientation of magnetic drill, it is made not influenced by flange inner wall curved surface, can be with cross drilling, and stability is good, and drilling quality is high, the Tapping Quality after ensure that.
Description
Technical field
The utility model is related to a kind of wind power flange inner wall auxiliary drilling tool, specifically a kind of drilling tool.
Background technology
As offshore wind farm installed capacity constantly increases, the wind power flange specification to be formed a complete production network also increases therewith, in
Screw thread bore dia needed for wall is also increasing, and thread Pilot hole small in the past can pass through drilling of electric hand drill after scribing line, present spiral shell
After pit is more than M8, thread Pilot hole drilling is just very laborious using drilling of electric hand drill, and borehole accuracy is not high, leads to tapping situation not
It is good.
Utility model content
The purpose of this utility model is to provide a kind of simple in structure, operated and be easy using process, can facilitated and different rule
Lattice flange is fitted close, and the auxiliary drilling tool that thread Pilot hole is processed is completed in conjunction with magnetic drill；Wind power flange inner wall drilling auxiliary
Tooling includes main body and clamping screw composition.
Wind power flange inner wall auxiliary drilling tool, it is characterised in that：
Including main body, the main body is welded by inverted concave panel, support plate, bottom plate, backboard, the inverted concave panel
It is carved with a center line in centre；Support plate one end is connected to inverted concave upper panel, and the other end is connected on bottom plate；Bottom plate one end
It vertically and is welded on inverted concave panel, the other end is vertical and is welded on backboard.
It is drilled with threaded hole everywhere at four angles on the backboard, is rotatablely connected with clamping screw.
The clamping screw, end are polished into hemispherical.
The advantage of the utility model：
The utility model is simple in structure, at low cost, and securely and reliably, performance is stablized, easy to use, and has adjustable extent
Greatly, cooperation magnetic drill use can guarantee drilling quality, and production efficiency is also improved while reducing operator's labor intensity；
The auxiliary drilling tool cleverly changes the operative orientation of magnetic drill, it is made not influenced by flange inner wall curved surface, can be lateral
Drilling, stability is good, and drilling quality is high, the Tapping Quality after ensure that.

Based on therein 1,2 be clamping screw, 3 be panel, 4 be support plate, 5 be bottom plate, 6 be backboard, 7 be flange.
Specific implementation mode
Embodiment
As shown in FIG. 1, FIG. 1 is the overall structure diagram of wind power flange inner wall auxiliary drilling tool, in the wind power flange
Wall auxiliary drilling tool includes main body 1 and 4 clamping screws 2.As shown in figure 4, Fig. 4 is wind power flange inner wall auxiliary drilling tool
Combining closely for the tooling and flange 7 may be implemented by adjusting clamping screw 2 in operating diagram.
As shown in Fig. 2, structural schematic diagram based on Fig. 2, main body 1 by panel 3, support plate 4, bottom plate 5, the welding of backboard 6 and
At.A center line is carved in 3 one side centre position of panel, facilitates magnetic drill drilling centering by the center line；Panel 3 is undercut
Shape panel, lower end concave-shaped openings are to be provided with working space, can conveniently observe that position is got in flange inner wall scribing line ready by working space
It sets.Have threaded hole everywhere on backboard 6, by 2 fastening device of clamping screw, by adjust clamping screw can realize main body from it is different
Specification flange is fitted close.
As shown in figure 3, Fig. 3 is 2 schematic diagram of clamping screw, the end of clamping screw 2 be polished into it is hemispherical, the purpose is to
It causes to scratch to flange excircle when in order to reduce clamping, ensures flange as a whole quality.
It should be can be achieved from wind power flange inner wall auxiliary drilling tool to wind power flange inner wall by being used cooperatively with magnetic drill
Accurate drilling, simple in structure, at low cost, securely and reliably, performance is stablized, easy to use, and big with adjustable extent, ensures
Drilling quality, while reducing operator's labor intensity also improves production efficiency.
