One end that described drilling equipment 7 is T shape frame 16 top flanges is provided with drill bit 17 by control lever, the other end of T shape frame 16 top flanges is provided with the motor of controlling drill bit 17 High Rotation Speeds, control gear 18 is installed on described control lever, the middle part of fork 19 is hinged on T shape frame 16, one end of described fork 19 is the arc-shaped rack being meshed with control gear 18, one end of the other end of fork 19 and first connecting rod 20 is hinged, one end of the other end of first connecting rod 20 and second connecting rod 21 is hinged, the middle part of second connecting rod 21 is hinged on support plate 13, the other end of second connecting rod 21 is provided with slide block, on an end face of described control wheel disc 15, have cam path 22, the slide block of second connecting rod 21 is arranged in the cam path 22 of controlling on wheel disc 15.
In described frame 1, be installed with a wherein bench drill, another bench drill is arranged in frame 1 by removable slide unit 24, the below of described removable slide unit 24 is provided with screw mandrel 23, and the nut of screw mandrel 23 is fixed on below removable slide unit 24, and the screw rod two ends of screw mandrel 23 are fixed in frame 1.
Malta wheel indexing mechanism belongs to the one of intermittent motion mechanism, claims again by " Geneva mechanism ", and when its driving wheel rotates a circle, driven pulley can be done 1/6 circle rotation, so gearratio is 6:1.Pilot pin slides in groove, has just produced the effect of indirect driving.Wherein, pilot pin is with tangential direction entry and exit guide groove, therefore, in rotary course, impact phenomenon can not occur.And the circular portion of driving wheel can contact with the female parts of driven pulley, while making pilot pin not do drive actions, still can maintain relative state.This is prior art.
The course of work:
Screw the screw rod of screw mandrel 23, making the spacing between the drill bit 17 of two bench drills is the diplopore spacing on work piece, opens the motor of controlling rotating shaft 2 and the motor of controlling drill bit 17;
The power that the belt pulley 3 of rotating shaft 2 one end transmits by belt, driven rotary axle 2 rotates, rotating shaft 2 drives the control wheel disc 15 of installation on it and the driving wheel 8 of Malta wheel indexing mechanism to rotate respectively 60 °, bearing 14 on motion bar 12 rises as fulcrum rotates take the other end being hinged on support plate 13 after turning over the deep-slotted chip breaker of controlling on wheel disc 15, the middle part of motion bar 12 is by pressing plate 11 one end jack-up, because pressing plate 11 middle parts are hinged on bearing, so the other end of pressing plate 11 declines, now because the driving wheel 8 of Malta wheel indexing mechanism rotates 60 ° and to drive driven pulley 9 to rotate 60 ° of rear main wheels separation with driven pulley, the interior drive one velamen workpiece of a chute feeder 10 on driven pulley rotates to the below of pressing plate 11 pressing plate 11 being lowered by and is fixed,
Rotating shaft 2 continues to drive the driving wheel 8 of controlling wheel disc 15 and Malta wheel indexing mechanism to rotate 300 °, in this process, motion bar 12 keeps by the state of jack-up, therefore pressing plate 11 compresses work piece always, due to Malta, take turns the disengaging of indexing mechanism driving wheel 8 and driven pulley 9 simultaneously, driven pulley 9 is unchanged, the cam path 22 of controlling on wheel disc 15 end faces is controlled second connecting rod 21 rise and fall, and by first connecting rod 20, the effect control drill bit 17 of fork 19 and control gear 18 declines and the stroke rising, driven by motor drill bit 17 High Rotation Speeds in this process, complete the boring of work piece,
So far, process at one time.
When rotating shaft 2 continues rotation, process is same as above, and the driven pulley 9 continuation rotations of Malta wheel indexing mechanism, in the time of processing, finished work piece is decontroled and is fallen.
By reference to the accompanying drawings embodiments of the invention are explained in detail above, but the present invention is not limited to above-described embodiment, in the ken possessing those of ordinary skills, can also under the prerequisite that does not depart from aim of the present invention, makes various variations.
