Description
Technical field
The utility model relates to drill processing device fields, specifically four-head vertical adjustable drilling machine drill bit frame.
Background technique
In the prior art, drill bit bracket, which is adjusted, generally uses four axis drill bit frame of gear adjustable, and concrete principle is idle pulley
When axis is rotated along driving shaft sun gear, the adjustability of opposite central gear center can be from making in axis satellite gear 5
Heart position (bit central position) obtains, not only adjustable halving hole system but also can be with hole system diameter adjustment when there is extension to adjust
Advantage, but range adjusting is relatively small, it is difficult to realize a wide range of, general orientation adjusting.
Utility model content
The technical problem to be solved by the utility model is to provide four-head vertical adjustable drilling machine drill bit frames, to solve existing skill
Defect present in art.
The technical solution that the utility model solves above-mentioned technical problem is as follows:
Four-head vertical adjustable drilling machine drill bit frame, including drill bit frame input shaft connect the sun by angular contact ball bearing one
Gear, sun gear are connect with angular contact ball bearing two, and the side of the drill bit frame input shaft, which is arranged side by side, idler shaft, described
Planet gear wheel, the planet gear wheel and sun gear engagement rotation are connected by needle bearing above idler shaft, it is described lazy
Satellite gear wheel, the satellite gear wheel and planet pinion engagement rotation are connected with below wheel shaft, planet pinion drives rolling
Needle and the rotation of thrust ball built-up shaft, to drive the fluted drill rotation work of two sides；The driving of angular contact ball bearing two lower section
The fluted drill rotation work of axis connection.
Further, drill bit frame input shaft periphery is arranged with the sleeve to shield, and the sleeve passes through screw
It is fixedly connected in drill bit frame.
Further, the fluted drill passes through screw thread and axis connection.
The beneficial effects of the utility model are: when work, the small tooth of planet of four axis drill bit frame needle rollers and thrust ball built-up shaft
The lower half portion of wheel and idler shaft planet gear wheel can be used as unified entirety and rotate around idler shaft, can be adjusted in this way
Divide hole system again can be with hole system diameter adjustment, it can be achieved that a wide range of, general orientation adjusting.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the face the B-B cross-sectional view in Fig. 1；
The reference numerals are as follows:

Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
As shown in Figure 1, four-head vertical adjustable drilling machine drill bit frame, including drill bit frame input shaft 1, pass through angular contact ball bearing
One 2 connection sun gears 12, sun gear 12 are connect with angular contact ball bearing 2 11, and the side of the drill bit frame input shaft 1 is simultaneously
Row is provided with idler shaft 3, connects planet gear wheel 4 by needle bearing 5 above the idler shaft 3, the planet gear wheel 4 with
12 engagement rotation of sun gear is connected with satellite gear wheel 6, the satellite gear wheel 6 and the small tooth of planet below the idler shaft 3
8 engagement rotations are taken turns, planet pinion 8 drives needle roller and thrust ball built-up shaft 7 to rotate, so that the fluted drill 10 of two sides be driven to rotate
Work；10 rotation work of fluted drill of the driving of angular contact ball bearing 2 11 lower section axis connection；
Further, 1 periphery of drill bit frame input shaft is arranged with the sleeve to shield, and the sleeve passes through screw
It is fixedly connected in drill bit frame；
Further, the fluted drill 10 is easy to disassemble by screw thread and axis connection；
Concrete operating principle: the planet gear wheel of idler shaft is rotated along the sun gear of drill bit frame input shaft, needle roller and is pushed away
The planet pinion of power ball built-up shaft along idler shaft planet gear wheel rotation and meanwhile when carrying out, not only adjustable halving hole system but also
It can be with hole system diameter adjustment；When work, the planet pinion and idler shaft planet of four axis drill bit frame needle rollers and thrust ball built-up shaft
The lower half portion of gear wheel can be used as unified entirety and rotate around idler shaft, and halving hole system can be adjusted so again can be with hole
It is diameter adjustment.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
