Abstract
The utility model discloses a screw tap holder for drilling screw holes in a wind power flange and relates to a hand-operated tool used for drilling the screw holes during machine manufacturing. By means of the screw tap holder, when tapping hitch is performed manually, force is applied to a screw tap uniformly, and a cutting blade of the screw tap and the screw holes can be protected. The screw tap holder is characterized by comprising a cylindrical screw tap fixing seat (1) which is vertically arranged, wherein a blind hole (101) is formed in the lower end surface of the screw tap fixing seat (1), a screw (3) for performing fastening is arranged on the cylindrical surface of the screw tap fixing seat (1), a moving lever (2) is arranged on the upper end surface of the screw tap fixing seat (1), and two lever ends of the moving lever (2) respectively exceed the upper end surface of the screw tap fixing seat (1) and respectively extend towards the ends. The screw tap holder for drilling the screw holes in the wind power flange is simple in structure.
Description
[technical field]
The utility model belongs to machinery manufacturing technology field.Especially relate to the hand-operated tools that in a kind of machine-building process, the auger shell pit uses.
[background technology]
At present, in the machine-building process, the processing and fabricating screwed hole is all that work piece is clamped on platen, by the tapping head follow procedure automatic thread cutting of its lathe, is undertaken, and high being applicable to of its product percent of pass produce in enormous quantities.For the diameter of small lot batch manufacture or the single-piece production wind power flange at 3-5 rice, because its workpiece inconvenience is mobile, the processing and fabricating of its screwed hole is all undertaken by pincers worker master worker operator power driven tools, its hand-operated tools comprises screw tap and spanner etc., although it is convenient that use screw tap and spanner etc. carry out the processing and fabricating of screwed hole, but production efficiency is very low, part simultaneously also comes with some shortcomings, its weak point is: during manual operation, the axis of screw tap is difficult for controlling, be prone to or dancing, cause the blade of screw tap or screwed hole all to damage.
[summary of the invention]
Task of the present utility model is to provide the screw tap bracket that a kind of wind power flange auger shell pit is used.During its pincers worker manual operation tapping hitch, screw tap is stressed, and evenly its axis is easily controlled, and reduces its inclination or dancing, blade and the screwed hole of protection screw tap.
The technical solution of the utility model is as follows:
The screw tap bracket that a kind of wind power flange auger shell line is used, include the screw tap holder 1 of the perpendicular cylindrical shape of putting, its characteristics are: the blind hole 101 that is provided with its central axis cylindrical shape consistent with the central axis of screw tap holder 1 on the lower surface of screw tap holder 1, and the tapped through hole 102 that the central axis that is provided with its central axis and blind hole 101 on the periphery of screw tap holder 1 intersects vertically, simultaneously, at the interior tightening screw 3 that arranges of tapped through hole 102;
On the upper surface of described screw tap holder 1, be provided with the moving bar 2 of the cylindrical shape that the central axis of its central axis and screw tap holder 1 intersects vertically, two thick stick ends of its moving bar 2 exceed respectively the upper end face of screw tap holder 1 and to the outer prolongation respectively of end.
For preventing that tightening from loosening or obscission occurring with screw 3, in the tightening of tapped through hole 102 interior settings, with exposing on screw surface of screw 3, be provided with the nut 4 of locking use.
For making the stressed even prolongation of screw tap its service life, two thick stick ends of its moving bar 2 exceed respectively the upper end face of screw tap holder 1 identical to the length of the outer prolongation respectively of end.
The utility model in use, because two thick stick ends of its moving bar 2 exceed respectively the upper end face of screw tap holder 1 identical to the length of the outer prolongation respectively of end, on its pincers worker master worker left and right arms, have an effect evenly, and the plane balancing state of moving bar 2 easy to control, cause screw tap central axis balance and stability and be consistent, not there will be to tilt or dancing, having extended the service life of screw tap blade, also improve simultaneously the making precision of screwed hole, guaranteed product quality.
The beneficial effects of the utility model are as follows: owing to using technique scheme, realized that screw tap is stressed even, its axis is easily controlled, and has reduced inclination or dancing, the blade of protection screw tap and the technique effect of screwed hole.The utility model is simple in structure.

[specific embodiment]
The utility model is described in further detail below in conjunction with accompanying drawing.
In Fig. 1 Fig. 2 Fig. 3 Fig. 4 Fig. 5 Fig. 6 first embodiment shown in Figure 7, the screw tap bracket that a kind of wind power flange auger shell line is used, include the screw tap holder 1 of the perpendicular cylindrical shape of putting, its characteristics are: the blind hole 101 that is provided with its central axis cylindrical shape consistent with the central axis of screw tap holder 1 on the lower surface of screw tap holder 1, and the tapped through hole 102 that the central axis that is provided with its central axis and blind hole 101 on the periphery of screw tap holder 1 intersects vertically, simultaneously, at the interior tightening screw 3 that arranges of tapped through hole 102;
On the upper surface of described screw tap holder 1, be provided with the moving bar 2 of the cylindrical shape that the central axis of its central axis and screw tap holder 1 intersects vertically, two thick stick ends of its moving bar 2 exceed respectively the upper end face of screw tap holder 1 and to the outer prolongation respectively of end.
For preventing that tightening from loosening or obscission occurring with screw 3, in the tightening of tapped through hole 102 interior settings, with exposing on screw surface of screw 3, be provided with the nut 4 of locking use.
For making the stressed even prolongation of screw tap its service life, two thick stick ends of its moving bar 2 exceed respectively the upper end face of screw tap holder 1 identical to the length of the outer prolongation respectively of end.
In use, the interior screw tap 5 that arranges of blind hole 101, and fixing with screw 3 with tightening, with nut 4 lockings for the utility model.
Because two thick stick ends of its moving bar 2 exceed respectively the upper end face of screw tap holder 1 identical to the length of the outer prolongation respectively of end, on its pincers worker master worker left and right arms, have an effect evenly, and the plane balancing state of moving bar 2 easy to control, cause screw tap central axis balance and stability and be consistent, not there will be to tilt or dancing, extend the service life of screw tap blade, also improved the making precision of screwed hole simultaneously, guaranteed product quality.
