Abstract
The utility model provides a kind of circuit board locating and machining structure, including circuit board, alignment pin and numerical control machine tooling table top, dowel hole is offered on the circuit board, positioning hole is offered on the Digit Control Machine Tool processing table top, the alignment pin lower end is removably inserted into the positioning hole after passing through the dowel hole.When the utility model can be effectively prevented from being processed circuit board, the problem of alignment pin is easily trained off reduces scrapping for circuit board.
Description
Technical field
The utility model is related to circuit board manufacturing area, more particularly to a kind of circuit board locating and machining structure.
Background technology
Digit Control Machine Tool is in operation, and pcb board part must use alignment pin to be fixed, and prevents PCB when Digit Control Machine Tool is processed
Plate off normal, causes product rejection, is drilled after alignment pin positioning hole, is fixed using suitable alignment pin.But, it is fixed beating
Because operational issue during the pin of position, alignment pin has the risk trained off.
Utility model content
The utility model provides a kind of circuit board locating and machining structure, to solve in the prior art to add circuit board
Man-hour, the problem of alignment pin is easily trained off.
To solve the above problems, as one side of the present utility model there is provided a kind of circuit board locating and machining structure,
Including circuit board, alignment pin and numerical control machine tooling table top, dowel hole is offered on the circuit board, the Digit Control Machine Tool adds
Positioning hole is offered on work table top, the alignment pin lower end is removably inserted into the positioning hole after passing through the dowel hole
In.
Preferably, the thickness of the circuit board is 3 millimeters.
Preferably, the diameter of the dowel hole is equal to the diameter of the positioning hole, and the diameter of the positioning hole is more than
0.05 millimeter of the diameter of the alignment pin.
Preferably, a diameter of 2.5 to 3 millimeters of the dowel hole.
By adopting the above-described technical solution, when the utility model can be effectively prevented from being processed circuit board, positioning
The problem of pin is easily trained off, reduces scrapping for circuit board.

Embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing, but the utility model can be by right
It is required that the multitude of different ways for limiting and covering is implemented.
The utility model provides a kind of circuit board locating and machining structure, including circuit board 1, alignment pin 2 and Digit Control Machine Tool
Process and dowel hole 4 offered on table top 3, the circuit board 1, positioning hole 5 is offered on the Digit Control Machine Tool processing table top 3,
The lower end of alignment pin 2 is removably inserted into the positioning hole 5 after passing through the dowel hole 4.
In use, the positioning hole 5 for getting out and being needed when circuit board 1 is positioned on table top 3 is first processed in Digit Control Machine Tool, then will be fixed
Position pin 2 is put into the dowel hole 4 of circuit board 1, the positioning hole 5 on alignment numerical control machine tooling table top 3, to realize positioning.
By adopting the above-described technical solution, when the utility model can be effectively prevented from being processed circuit board, positioning
The problem of pin is easily trained off, reduces scrapping for circuit board.
Preferably, the thickness of the circuit board 1 is 3 millimeters.
Preferably, the diameter of the dowel hole 4 is equal to the diameter of the positioning hole 5, and the diameter of the positioning hole 5 is big
In 0.05 millimeter of the diameter of the alignment pin.
Preferably, a diameter of 2.5 to 3 millimeters of the dowel hole 4.
Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, for this
For the technical staff in field, the utility model can have various modifications and variations.It is all it is of the present utility model spirit and principle
