Problems solved by technology

[0002] When drilling printed circuit boards, in order to prevent drilling deviation, drill bit breakage and poor drilling quality, presser feet are added when the main shaft of the drilling rig touches the board surface. Before drilling, the presser feet first press the board surface. Then drill again, but because the diameter of the drill bit is different, it will affect the drilling quality and hole position accuracy. Therefore, in order to ensure the drilling quality and hole position accuracy, it is necessary to replace different diameter drill bits according to different drill bit diameters during drilling. The presser foot is now replaced manually, which will easily cause the installation position of the presser foot to be inaccurate after replacement, thus affecting the drilling quality and hole position accuracy

Embodiment approach

[0044] The specific implementation is described as follows:

[0045] Such as figure 1 As shown, when the presser foot on the left side of the base 400 needs to be replaced, the linear mechanism is first activated to move the support base 100 to the corresponding position of the base 400, and then the turning mechanism is activated so that the support base 100 is directly above the base 400. Then start the first motor 202 located on the left side, drive the screw mandrel 201 in the first chute 101 to rotate, make the slide block 203 move towards the base 400 from the position of the lifting frame 306, start the first telescopic link 204, and make the connecting plate 205 Move downwards. During the movement, the clamping rod 206 passes through the hole on the presser foot. Since the movable plate 210 is hinged to the lower end of the support plate 207, the movable plate 210 is lifted up by the presser foot to avoid the clamping process. 210 interferes with the presser foot, and...
