Like this, in boring machine drill plate process, borehole cuttings is discharged by chip removal mouth by negative pressure, simultaneously by the intake channel air inlet, form eddy current, drill bit is played cooling effect, and can remove the smear metal of twining or attaching on the drill bit, brill plate precision and hole wall quality have been improved, reduced the broken needle rate simultaneously, in addition, the utility model can conveniently be changed presser feet, not only reduced use cost, and can select the pressure foot of different structure for use according to actual conditions.
Description of drawings
Fig. 1 is the cross-sectional schematic of the utility model one preferred embodiment;
Fig. 2 is the cross-sectional schematic of Fig. 1 along the A-A line.
The specific embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Please refer to Fig. 1 and Fig. 2, be a preferred embodiment of the utility model printed circuit board drilling machine chip removal mechanism, described drilling machine comprises drill bit 1, drives the main shaft 2 and the presser feet (not shown) of described drill bit 1 rotation.Described chip removal mechanism comprises the suction bits cover 3 that is sheathed on described main shaft, in the present embodiment, inhale bits cover 3 and be an inverted straw hat shape, described suction bits cover 3 tops are provided with the turn-up portion 31 that is connected with drilling machine, described suction bits cover 3 bottoms are provided with the through hole 34 that stretches for described drill bit 1, can realize removably connecting to described presser feet by described through hole 34.Described suction bits cover 3 sidewalls are provided with chip removal mouth 32, and the position of the corresponding described drill bit 1 of described suction bits cover 3 lower sides is provided with a plurality of inlet channels 33.Described a plurality of inlet channel 33 is evenly distributed on the bottom of described suction bits cover 3.Like this, in boring machine drill plate process, by negative pressure borehole cuttings is discharged by chip removal mouth 32, simultaneously by intake channel 33 air inlets, form eddy current, drill bit 1 is played cooling effect, and can remove the smear metal of twining or attaching on the drill bit 1, improve brill plate precision and hole wall quality, reduced the broken needle rate simultaneously.
As a kind of optimal way, the area summation of described a plurality of inlet channel 33 cross sections is less than the area of described chip removal mouth 32 cross sections.Like this, can near drill bit 1, form more high speed airflow, be beneficial to remove to twine or stick with drill bit 1 on smear metal, also improved its cooling effect to drill bit 1.
