Efficient process the abnormal tool for removing printed circuit board (PCB) PTH copper facing hole burs of edge PTH hole hole inner burr.
According to the technical scheme that the present invention is provided, the tool for removing printed circuit board (PCB) PTH copper facing hole burs, bag
Base plate is included, offer alignment pin nail in the upper surface of base plate processes pin hole with burr, and alignment pin nail processes pin with burr
Nail is blind hole, and shop bolt is housed in alignment pin nail interpolation, and burr treatment pin is fitted with burr treatment pin hole
Nail, perpendicular to the plane where base plate, burr processes the axis of pin perpendicular to the plane where base plate to the axis of shop bolt,
The height of the upper surface that burr treatment pin exposes base plate exposes the height of the upper surface of base plate less than shop bolt；From lower past
On direction on, the upper end of burr treatment pin and shop bolt is diametrically gradually reduced shape.
The burr processes a diameter of 1.0 ~ 5.0mm of pin, and burr treatment pin exposes the height of the upper surface of base plate
It is 6 ~ 12mm to spend..
A diameter of 1.0 ~ 5.0mm of the shop bolt, and shop bolt expose the height of the upper surface of base plate for 16 ~
19.8mm。
The base plate is square plate, circular flat board or I-shaped flat board.
The present invention can more rapidly, simply and efficiently process edge PTH hole hole inner burr in printed substrate, improve personnel
The efficiency for the treatment of, quality in the guarantee edge PTH hole hole of bigizationner；Simple structure of the present invention and convenient making.
Brief description of the drawings
Fig. 1 is front view of the invention.
Fig. 2 is top view of the invention.
Specific embodiment
With reference to specific embodiment, the invention will be further described.
This is used to remove the tool of printed circuit board (PCB) PTH copper facing hole burs, including base plate 1, is opened up in the upper surface of base plate 1
There is alignment pin nail to process pin hole with burr, alignment pin nail is blind hole with burr treatment pin hole, in alignment pin nail
Inside be fitted with shop bolt 3, be fitted with burr treatment pin 2 in burr treatment pin hole, the axis of shop bolt 3 perpendicular to
Plane where base plate 1, perpendicular to the plane where base plate 1, burr treatment pin 2 exposes bottom to the axis of burr treatment pin 2
The height of the upper surface of plate 1 exposes the height of the upper surface of base plate 1 less than shop bolt 3；On direction from the bottom up, burr
Treatment pin 2 is diametrically gradually reduced shape with the upper end of shop bolt 3.
The burr processes a diameter of 1.0 ~ 5.0mm of pin 2, and burr treatment pin 2 exposes the upper surface of base plate 1
Highly it is 6 ~ 12mm..
A diameter of 1.0 ~ 5.0mm of the shop bolt 3, and shop bolt 3 expose the upper surface of base plate 1 height be 16
~19.8mm。
The base plate 1 is square plate, circular flat board or I-shaped flat board.
When making, the profile of base plate 1 selects the size selection according to printed circuit board (PCB), the size ratio of base plate 1 to the present invention
The unilateral big 20mm of actual track plate appearance and size；The diameter of the shop bolt 3 on base plate 1 is come by the positioning aperture of wiring board edges of boards
It is determined that, the diameter of shop bolt 3 is than the small 0.1mm of positioning bore dia；Deburring pin 2, by actually being needed in printed substrate
The edge PTH hole pore size of heavy industry determines, when base plate 1 is selected need to than the PTH small 0.15mm of copper facing bore dia of plate domestic demand heavy industry, with
Conveniently move up and down.Above deburring pin 2 is all vertically fixed on base plate 1.
Embodiment 1
Certain 10 layer printed circuit board, there are 2.5mm, 1.6mm, 1.0mm and 0.8mm diameter in PTH copper facing hole in printed circuit board, fixed
