Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Examples
This embodiment provides a high accuracy PCB gong board production locating plate, as shown in fig. 1-2, high accuracy PCB gong board production locating plate specifically includes:
the positioning plate comprises a positioning plate body 3, wherein a positioning hole 1 is formed in the positioning plate body 3, the positioning hole comprises a first positioning hole 12 and a second positioning hole 11 which are concentric and communicated with each other, and the aperture of the second positioning hole 11 is 0.05mm smaller than that of the first positioning hole 12.
As shown in fig. 3, the aperture of the second positioning hole is smaller than that of the first positioning hole 12 by 0.05mm, and the problem that the existing positioning pin is easy to loosen and bend on the preformed hole of the positioning plate body 3 is solved through the two-stage aperture design.
Further, the thickness of the positioning plate body 3 is 12mm, and the depth of the positioning hole 1 is 6 mm. The positioning plate body 3 is used for drilling a positioning hole 1, and a positioning pin is arranged in the positioning hole 1 to fix the PCB.
Further, as shown in fig. 3, the first positioning hole 12 has a depth of 3 mm.
Specifically, the positioning hole 1 is manufactured by the following process: firstly, drilling a deep hole with the depth of 6mm and the diameter the same as the aperture of the second positioning hole 11 on the positioning plate body 3, and then carrying out reaming treatment on the deep hole to obtain a hole with the diameter the same as the aperture of the first positioning hole 12 and the depth of 3mm, thereby obtaining the first positioning hole 12 and the second positioning hole 11 which have the aperture difference of 0.05mm and are communicated with each other.
Further, as shown in fig. 3, a positioning pin 4 is disposed in the positioning hole 1, and the diameter of the positioning pin 4 is the same as the diameter of the first positioning hole 12.
