Description
Technical field
A kind of drilling tool is the utility model is related to, especially suitable for being used on protective cover during drilling.
Background technology
To improve the service life of motor and lowering maintenance cost, protective cover is equipped with the end cap of existing motor, is prevented
Fastened after drilling on shield by screw and end cap, on existing protective cover drilling first have to line indexing by hand, when drilling, does not have yet
There is fixing tool, at least need two operative employees to complete, the hand steered workpiece of a people, people drilling, until on protective cover
Mounting hole is drilled, the drawback is that, waste of manpower, efficiency are low, and increase production cost.
The content of the invention
The task of the utility model is to propose a kind of reduction production cost, carries drillman on a kind of efficient protective cover
Dress.
The task of the utility model, which is done in such a way that, is characterized in that：Drilling tool is fixed on the workbench of drilling machine
On, four angles of base are fixed by bolt and workbench, a positioning plate are vertically welded with the center line of base, in positioning plate
Centre position be fixed with a round bump, three ring-shaped steps, the annular table are at least machined with the round bump
The diameter of rank tapers into center and is reserved with axis hole, and be equipped with screw in axis hole is fixed by nut, the week of the round bump
Enclose and be machined with positioning pin nail, the back side of positioning plate is welded with supporting.The shape of the base is in square or rectangle, described fixed
Position plate is the steel plate of one piece of square.One end of supporting and tube chamber welds with base, the other end are formed by welding a backrest with positioning plate.
The utility model has the following effects that：The technical program is not only applicable in the drilling of protective cover, is equally also suitable motor
Drilling on end cap, during drilling, a people just can operate, and manpower be saved, so as to lower production cost.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model；Fig. 2 is the drilling tool structure diagram of Fig. 1.
Drawing explanation：1st, workbench, 2, base, 3, positioning plate, 4, positioning pin nail, 5, round bump 6, annular table
Rank 7, screw, 8, supporting, 9, radial drilling machine, 10, workpiece.
Embodiment
Embodiment is described in detail with reference to the figures above, the technical program drilling tool is fixed on the workbench 1 of radial drilling machine 9
On, the drilling tool is made of base 2, positioning plate 3, positioning pin nail 4, round bump 5 and supporting 8, four of base 2
Angle is fixed by bolt and workbench 1, and the shape of the base is in square or rectangle, is vertically welded with the center line of base
One positioning plate 3, the positioning plate are the steel plates of one piece of square, and a round bump is fixed with the centre position of positioning plate
5, three ring-shaped steps 6 are at least machined with the round bump, it is therefore an objective to corresponded to and installed according to the size of protective cover axis hole, institute
The diameter for stating ring-shaped step tapers into center and is reserved with axis hole, and screw 7 is equipped with axis hole and is fixed by nut, designs screw
Purpose be workpiece when conveniently processing handling, when filling Workpiece boring among have the transition of an interval, the round bump
Surrounding is machined with positioning pin nail, and the back side of positioning plate is welded with supporting 8, supports 8 one end and tube chamber welds with base, the other end and positioning
Plate is formed by welding a backrest, it is therefore an objective to makes positioning plate more firm.
The positioning plate can also use two block length cube steel plate pieces to dock, and two steel plate edge joint positions are welded with positioning plate.
During work, first by workpiece 10, workpiece refers to that protective cover or end cap are placed on screw, then again by protective cover or end
The axis hole covered assembling corresponding with the ring-shaped step on round bump, pierces into dowel hole fixation with pin, fixes
The drill hole of protective cover and end cap is higher than the top margin on positioning plate top, is directly drilled with the drill bit on radial drilling machine, this drillman
Dress can be more prone to the drilling on protective cover and end cap, and a people just can operate, so as to reduce production cost.
