Abstract
Based on a traditional polychlorinated biphenyl (PCB) miller pressing foot seat, a pressing foot base cover plate is arranged on an aluminous substrate milling gas-blowing pressing foot of a printed plate numerically-controlled machine tool. Gas containing alcoholic is blown into a gap between the pressing foot base cover plate and the pressing foot base, in the process of processing, heat on a milling cutter and a aluminous substrate is taken away through volatilization of the alcohol, and therefore a purpose of reducing the temperature of the milling cutter and the aluminous substrate is achieved.
Description
Affiliated technical field
The utility model relates to the contour milling processing of pcb board contour milling manufacture field, especially aluminium base.
Background technology
At present, common PCB milling machine is in to the processing of the contour milling of aluminium base, and is fast because of generating heat, heat production is concentrated, heat is big; The as easy as rolling off a log cutter wear speed that causes is seriously aggravated; Even in milling process breaking, shortened service life of milling cutter greatly, simultaneously; Also can cause aluminium base Yin Wendu to raise, and the substrate burr that is milled into is increased.
Summary of the invention
In order to solve the deficiency of existing PCB milling machine to aluminium base milling ability; The utility model provides a kind of simple and convenient solution; This scheme can not only solve the serious problem that shortens of milling cutter life-span in traditional milling, and the Burr Problem in the solution aluminium base contour milling that can be good.
The utility model solves the scheme that its technical problem adopted: on traditional milling machine presser feet basis, the bottom adds a presser feet bottom plate, stays certain interval between the two, as gas channel; On woollen brush base, also have straight hole radially, gas can flow to milling cutter through straight hole.When the air inlet of presser feet bottom plate right-hand member has the air communication that has alcohol out-of-date; Air-flow flows to the gap between presser feet seat and the presser feet bottom plate along straight hole; Most of gas here is through the through hole on the presser feet bottom plate; Flow to aluminium base vertically downward, few part directly flows to milling cutter through radially straight hole in the woollen brush base and the slit between woollen brush base and the presser feet bottom plate, more vertically toward current downflow.After the gas of band alcohol flowed out from the air blowing presser feet, alcohol volatilized, and took away most of heat of milling cutter and aluminium base in the milling aluminium base process.Reach the purpose of cooling milling cutter and aluminium base.
The beneficial effect of the utility model is, can solve the cooling problem of milling cutter and aluminium base very easily, thus the service life of improving milling cutter greatly, and aluminium base also obtains corresponding cooling simultaneously, also can reduce the generation of aluminium base burr to a certain extent.Owing to be improvement on the original basis, so simple in structure, easy for installation.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the presser feet seat.
Fig. 2 is the vertical view of the utility model air blowing presser feet bottom plate.
Fig. 3 is the front view of presser feet bottom plate.
Fig. 4 is the structural map that presser feet bottom plate and presser feet seat fit together.
Specific embodiments
In Fig. 1, be the normal axomometric drawing of presser feet seat.
In Fig. 2; Four φ that is uniformly distributed with 3.5 through holes are fixed through screw and presser feet seat, and eight φ that is uniformly distributed with 2 through holes are steam vents, after from then on the gas of band alcohol got rid of; Take away a large amount of heats; Play the effect of cooling milling cutter and aluminium base, right-hand member φ 3d straight hole is an air intake duct, and the screwed hole of M5 is the gas connector interface.
In Fig. 3, φ 3.3 straight hole right-hand member tapping are sealed with lock-screw, and this is to be convenient to processing.
In Fig. 4, presser feet seat (1) and presser feet bottom plate (5) with screw attachment together, woollen brush base (2) connects with presser feet seat (1), milling cutter (3) is clamped in electric main shaft (figure slightly) goes up, hairbrush (4) connects with woollen brush base.
Claims (3)
1. printed board Digit Control Machine Tool aluminium base milling air blowing presser feet adds a presser feet bottom plate in presser feet seat bottom, it is characterized in that: between presser feet seat and presser feet bottom plate, form certain interval, as the passage of band alcohol refrigerating gas.
2. printed board Digit Control Machine Tool aluminium base milling air blowing presser feet according to claim 1, it is characterized in that: presser feet seat (1) comprises woollen brush base (2) and hairbrush (4) presser feet bottom plate (5).
