Abstract

The invention provides a fixture for drilling of a PCB, and relates to the technical field of electronic product production. The fixture for drilling of the PCB comprises a mounting base, and two rotating seats are fixedly mounted on the top of the mounting base. According to the fixture for drilling of the PCB, through matching of the mounting base, the rotating seats, transverse rods, rotating handles, clamping rods, adjusting rotary knobs, pressing blocks, rubber blocks and a drilling plate, the relative positions of the transverse rods and the clamping blocks on the top of the drilling plate can be adjusted through the rotating handles and the adjusting rotary knobs, and after adjusting is completed, the top surface of the to-be-drilled PCB can be clamped by utilizing the pressing blocks and the rubber blocks; by arranging the clamping blocks, grooves and clamping springs, the positions of the clamping blocks on the two sides of the top of the drilling plate are adjusted through telescopic springs, and thus the two sides of the to-be-drilled PCB can be clamped; and in conclusion, through matching of two kinds of different clamping modes, the fixture for drilling of the PCB is good in clamping stability, and drilling of the PCB is more accurate, so that the produced PCB is good in quality.

Description

technical field [0001] The invention relates to the technical field of electronic product production, in particular to a jig for drilling holes in a PCB board. Background technique [0002] PCB board, the Chinese name is printed circuit board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components. In order to meet the installation of devices, PCB boards need to pass Drilling machine processing device mounting holes, because the PCB board is brittle and has low tensile strength, poor splitting is prone to occur when drilling directly. The existing method uses the PCB board to be placed between the backing plate and the cover plate for drilling. The size of the PCB board is not uniform, so the size of the matching backing plate and cover plate is also changed. Most of the existing fixtures are fixed structures, which are difficult to meet the clamping req...
