Design a kind of printed circuit board (PCB) drilling machine with big or small presser feet switching device shifter, comprise the suction bits cover that can be installed on the drilling machine Z axle, suction bits cover center has and can make the through hole that drill bit passes on the Z axle, inhale bits cover bottom and be dome shape, inhale middle part, the bits cover end deep-slotted chip breaker is arranged, an arc size presser feet switch boards is installed in the deep-slotted chip breaker, on the arc size presser feet switch boards on the corresponding drilling machine drill bit have the large and small presser feet of two different apertures through holes, described arc size presser feet switch boards moves the large and small presser feet of switching by being connected with transmission mechanism to be implemented in the deep-slotted chip breaker of inhaling the bits cover.
Transmission mechanism in the technique scheme includes the cylinder connecting plate of cylinder and cylinder drive, and the cylinder connecting plate is connected by spring driver plate and arc size switch boards.Arc size presser feet switch boards is fixed on by two spring pressuring plates in the deep-slotted chip breaker of inhaling the bits cover, realizes arc size presser feet switch boards and inhales no gap transmission between the bits cover by the pressure of spring pressuring plate.
Big presser feet on the arc size presser feet switch boards and little presser feet comprise the circular working face of a level respectively, are formed with angle between the working face of this large and small presser feet, on the large and small presser feet on the corresponding drilling machine through hole of drill bit be positioned at the center of working face.
For changing fast arc size presser feet switch boards, technique scheme is done further improvement, the dismountable snapping mode of employing is connected between spring driver plate and the arc size switch boards.
For making switching more accurate, on described suction bits cover, be equipped with and be used for confirming whether arc size presser feet switch boards switches the inductor that puts in place.
The utility model has following remarkable result compared to existing technology:
Printed circuit board (PCB) drilling machine of the present utility model is with big or small presser feet switching device shifter, this device is provided on the printed circuit board (PCB) drilling machine, when boring macropore, adjust and make arc size switch boards switch on the big presser feet, adjustment makes arc size switch boards switch on the little presser feet when boring aperture, has guaranteed the borehole accuracy requirement.
During the utility model design, between suction bits cover bottom and arc size presser feet switch boards, be designed to arc contact surface, arc size presser feet switch boards is that the elastic compression power by spring pressuring plate is pressed on it on arcwall face of inhaling the bits cover, by the driving of cylinder and spring driver plate, make arc size presser feet switch boards on suction bits cover, do the arc shift action.Arc size presser feet switch boards also makes large and small presser feet working face not at grade, makes its work interference-free, and exquisiteness simple in structure.
Adopt between arc size switch boards and the spring transmission version to removably connect, when needs are changed arc size presser feet switch boards,, realized the quick replacing of arc size switch boards like this as long as push the spring driver plate aside.
Description of drawings
Accompanying drawing 1 is the elevational schematic view after the utility model assembling;
Accompanying drawing 2 is A-A cross-sectional schematic of accompanying drawing 1.
The specific embodiment
With reference to the accompanying drawings 1,2, a kind of printed circuit board (PCB) drilling machine comprises and inhales bits cover 1 with big or small presser feet switching device shifter, inhales bits cover 1 and be used to be installed in drilling machine Z axle.Suction bits cover center has and can make the through hole that drill bit passes on the Z axle.Inhale bits cover 1 bottom and be dome shape, inhaling middle part, the bits cover end, just a deep-slotted chip breaker 11 is offered in the position of the longest string in sphere middle part at the bottom of the longest cover, and an arc size presser feet switch boards 2 is installed in deep-slotted chip breaker.
