Background technique
Large-scale wind electricity is the green clean energy resource that the world today is quickly grown, and wherein rotor field spider is in wind power generating set
Critical component on 3.0MW unit rotor bracket magnetic yoke inner wall, there is an oblique pole hole of 84 groups of-M depth 25mm, and totally 840;The hole need to be from
Processing inside magnetic yoke, it is desirable that high, general processing method: one is customization digital control special machine, realizing from internal efficient drilling, but
Digital control special machine is expensive, and the order cycle time is very long, is only applicable to large quantities of long-term productions;Another processing method is production magnetic yoke
Drilling die for integral drill, but drilling die for integral drill volume and weight is larger, and for general drill jig weight about at 7~9 tons, processing is complicated, and consuming is larger,
It is only suitable for producing in batches;The third is exactly the Simple hanging twist drill mould for making magnetic yoke inner wall, shortcoming be it is inefficient, positioning is not
Standard, hole location are not easy to guarantee.
Summary of the invention
In view of this, the main purpose of the present invention is to provide a kind of drill jigs and its processing method for magnetic yoke inclined hole.
In order to achieve the above objectives, the technical scheme of the present invention is realized as follows:
The embodiment of the present invention provides a kind of drill jig for magnetic yoke inclined hole, which includes connecting plate, transition plates, drill jig
Plate, the transition plates be it is horizontally disposed, the connecting plate is vertically set on above transition plates, and the bushing plate was vertically set on
Below cab apron;The through-hole for connecting with numerical control boring machine main shaft is provided on the connecting plate;The bushing plate is from top to bottom
It is provided with and several matched inclined holes of magnetic yoke inclined hole.
In above scheme, the first gusset is provided between the bushing plate and transition plates.
In above scheme, the second gusset is provided between the transition plates and connecting plate.
In above scheme, the on-fixed side of first gusset and the second gusset is an inclined-plane.
In above scheme, lifting of the lifting bolt for drill jig installation when is provided at the top of the connecting plate.
In above scheme, the bushing plate is provided centrally with a pair of of line peep hole.
The embodiment of the present invention also provides a kind of processing method of magnetic yoke inclined hole, and this method is realized by following steps:
Step 1: confirmation numerical control borer and NC rotary table model, precision meet processing request;
Step 2: numerical control borer being installed on to the side of NC rotary table, and confirms that preceding road scribing process has marked
Rotor centerline simultaneously extends to center line on magnetic yoke inner wall;
Step 3: the main shaft of drill jig and numerical control borer being connected, and beats dial gauge confirmation drill jig center line from drill jig side and hangs down
Straight degree meets the requirements, screw fastening;
Step 4: starting lathe, drill jig is put into inside rotor rim, with magnetic yoke inner wall longitudinal separation in accordance with boring requirement
Afterwards;Adjustment drill jig height meets the requirements;NC rotary table is rotated, by drill jig to line peep hole side and the preceding road institute of magnetic yoke
It draws center line to be overlapped, center centering;According to drawing requirement, first row bore position is rotated an angle to;
Step 5: NC rotary table is divided equally by figure oblique pole hole number of rows, is rotated by 360 ° beginning and end coincidence, verification ruler
Very little qualification;
Step 6: rotation magnetic yoke is accurately indexed by NC rotary table, it is complete on the inside of magnetic yoke by drill jig magnetic drill
At the point hole machined in the oblique pole hole of magnetic yoke.
Compared with prior art, beneficial effects of the present invention:
The present invention can be improved production efficiency, and average every used time is less than the magnetic yoke drilling die for integral drill used time, and operates and be easy;Add
Work precision is high, structurally reasonable.
