The tail end end indent formation one lower peace extended in the vertical direction of the top elbow part of head column (12)
Dress groove (121), connects in installing groove (121) and has a main spindle box (8) arranged along Z-direction, main
Main shaft assembly (14) is installed in axle box (8)；Install groove (121) relative main case (8) two
Being utilized respectively the first screw (19) on sidewall and be fixed with line rail slide block (16), main spindle box (8) is homologous pair
The position of rail slide block (16) is utilized respectively the second screw (20) and is fixed with a line arranged along Z-direction
Property guide rail (18), linear guides (18) and line rail slide block (16) are coupled and main spindle box (8) can be made to be pressed from both sides
Hold in groove (121) is installed and plummet can be made along its center of gravity direction and move.
The top elbow part of elbow column (12) is also equipped with Z-direction transmission module (9) and Z-direction ball enters
To screw mandrel (13), Z-direction transmission module (9) drives Z-direction roller feed screw mandrel (13) to rotate, and drives master
Axle box (8) does bottom and top feed motion in installing groove (121) along plummet direction.
The tail end of main spindle box (8) is provided with tool magazine support (7), tool magazine swing span (6) and tool magazine (4)；
The outside of main spindle box (8) is provided with and is available for the guide plate (5) that tool magazine (4) moves；Tool magazine support (7)

Now by as a example by a kind of vertical drilling and milling machining center (being commonly called as little Huang machine) of external import, analyze contrast
The present invention and the difference of little Huang machine once.
The present invention's is that elbow column bores Milling Machining center, first optimizes column, change biography on the basis of experiment
System right cylinder is elbow column, strengthens the cloth muscle of elbow, makes elbow part have enough rigidity, and two change cantilever
The main spindle box of formula is rectangular shaped post ram type main spindle box, and three change the mounting means of guideway, are existed by guide rails assembling
On the symmetric side of the existing both sides of main spindle box and main spindle box center of gravity galassing row, and by two, sliding block respectively is embedded in curved
Two ends inside head concave cross section, so that main spindle box can be in the case of zero cantilever moment, along vertical (weight
The heart) direction high-speed cruising.Solve cantilever (stretching) main spindle box therefore the main spindle box that caused of some cantilever moments
Problem of bowing, the equilibrium problem of main spindle box.Preferably resolve oscillation phenomenon during main spindle box high-speed cruising.
And partially cut moment and have also been obtained improvement extremely because of main shaft and guide rail Distance Shortened.
Seeing Fig. 5 and Fig. 6 position unbalance loading moment contrast schematic diagram, wherein Fig. 5 is the structural representation of little Huang machine,
Fig. 6 is the structural representation that elbow column of the present invention bores Milling Machining center.Lathe is adding man-hour, on main shaft
Cutter is produced cutting force, its Z-direction component Fz when excising the allowance of surface of the work, is consequently exerted at
Cutting component on main shaft.For column guide rail, it is exactly a kind of offset loading force.It is known that offset loading force
Amass with unbalance loading distance is unbalance loading moment.As shown in Figure 5: the distance of Z axis guide rail to the alignment of shafts is
450mm, this is with regard to the unbalance loading distance of little Huang machine, and this distance is bigger.And Z axis guide rail is to main shaft in Fig. 6
The distance at center is the least, the most only 60mm, and both differ 7.5 times more than, say, that
Under equal machining condition, the unbalance loading moment of import little Huang machine is 7.5 times of the unbalance loading moment of the present invention.Unbalance loading
Moment (moment of torsion) computational methods see below:
1, torque arithmetic: Nz=Fz × L
The medium and small yellow machine of Fig. 5: Nz=Fz × 450
The machining center of the present invention in Fig. 6: Nz=Fz × 60
2, comparing result: in the case of operating force is identical, the moment of torsion that little Huang machine Z axis guide rail bears is about
7.5 times of machining center of the present invention.
Shown the unbalance loading moment of the main spindle box of the present invention by above-mentioned calculating, bore Milling Machining center much smaller than tradition
The unbalance loading moment of main spindle box.Unbalance loading moment is the source of main tank vibration, add man-hour vibration can along with process velocity,
The increase of operating force and increase.Amplitude can directly influence the service life of guide rail, main shaft bearing, and lathe is firm
Property and processing characteristics.For improving the rigidity of main spindle box further, the headstock structure of the present invention uses similar big
Ram type high rigidity headstock structure used by type gantry plane, its good rigidly, can bear higher rotating speed, adds
Work performance also has and is greatly improved.
To sum up, elbow column of the present invention bores Milling Machining center, by being provided with one on lathe bed in inverted L shape
Elbow column, and form concave installation groove at the elbow part of elbow column, can divide in groove is installed
From connecting fixed main shaft case, install and be respectively fixed with a line rail slide block, main spindle box pair on two sidewalls of groove
The position answering line rail slide block be fixed with one can along Z-direction arrange linear guides, by line rail slide block with
The coupling of linear guides can make main spindle box be clamped in installation groove in and can do along its center of gravity direction plummet fortune
Dynamic.Elbow column of the present invention bores Milling Machining center, is different from tradition and bores the right cylinder that Milling Machining center is used,
Use elbow column can reduce unbalance loading moment and overhanging moment to greatest extent to main spindle box kinematic accuracy, static state
Precision and and machining accuracy impact so that main spindle box can be in the case of zero cantilever moment, along vertical
Direction high-speed cruising, solve main spindle box thus some cantilever moments caused the problem of bowing of main spindle box, master
The equilibrium problem of axle box, well solves oscillation phenomenon during main spindle box high-speed cruising.
Carry out although the description of this invention combines embodiments above, but, it is familiar with this technology neck
The personnel in territory can carry out many replacement, modifications and variations according to above-mentioned content, be apparent from.Cause
This, all such replacements, improve and change in the spirit and scope being included in appended claims.
