Detailed description of the invention
Below in conjunction with specific embodiment and accompanying drawing, elbow column of the present utility model is bored Milling Machining center to make further
Describe in detail.
Referring to Fig. 1 to Fig. 4, a kind of elbow column bores Milling Machining center, including lathe bed (1), saddle (2) and workbench
(3).The upper vertical of lathe bed (1) is provided with an elbow column (12) in inverted L shape, the top elbow part of elbow column (12)
Tail end end indent form a lower installation groove (121) extended in the vertical direction, connect in groove (121) is installed and have one
The main spindle box (8) arranged along Z-direction, is provided with main shaft assembly (14) in main spindle box (8)；Groove (121) relative main is installed
Being utilized respectively the first screw (19) on two sidewalls of case (8) and be fixed with line rail slide block (16), main spindle box (8) homologous pair rail is sliding
The position of block (16) is utilized respectively the second screw (20) and is fixed with a linear guides (18) arranged along Z-direction, linearly leads
Rail (18) and line rail slide block (16) are coupled in main spindle box (8) can be made to be clamped in installation groove (121) and can be along its center of gravity sides
To doing plummet motion.
The top elbow part of elbow column (12) is also equipped with Z-direction transmission module (9) and Z-direction roller feed screw mandrel
(13), Z-direction transmission module (9) drives Z-direction roller feed screw mandrel (13) to rotate, and drives main spindle box (8) along plummet direction in peace
Bottom and top feed motion is done in dress groove (121).
The tail end of main spindle box (8) is provided with tool magazine support (7), tool magazine swing span (6) and tool magazine (4)；Outside main spindle box (8)
Side is provided with and is available for the guide plate (5) that tool magazine (4) moves；One end of tool magazine support (7) and guide plate (5) be fixing to be connected, another
Holding the one end with tool magazine swing span (6) to fix to be connected, the other end of tool magazine swing span (6) is fixing with tool magazine (4) to be connected.
It is also equipped with when Tool changeover in main spindle box (8) unclamping the arm of forging a knife (10) of the cutter being tightened up and forging a knife convex
Wheel (11)；The tail end of main spindle box (8) and the position of close described main shaft assembly (14) are additionally provided with for cleaning tool magazine (4)
The nozzle (15) of cutter.
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 and contrast this reality
With novel and little Huang machine difference.
Of the present utility model is that elbow column bores Milling Machining center, first optimizes column, change tradition on the basis of experiment
Right cylinder is elbow column, strengthens the cloth muscle of elbow, makes elbow part have enough rigidity, and two change cantilevered main spindle box for long
Square column type ram type main spindle box, three change the mounting means of guideway, by guide rails assembling in the existing both sides of main spindle box and main spindle box center of gravity
On the symmetric side of galassing row, and by two, sliding block respectively is embedded in two ends inside elbow concave cross section, so that main spindle box
Can be in the case of zero cantilever moment, along vertical (center of gravity) direction high-speed cruising.Solve cantilever (stretching) main spindle box thus have outstanding
The problem of bowing of the main spindle box that arm strength square is caused, the equilibrium problem of main spindle box.When preferably resolving main spindle box high-speed cruising
Oscillation phenomenon.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, and Fig. 6 is this
Utility model elbow column bores the structural representation at Milling Machining center.Lathe is adding man-hour, and the cutter on main shaft is at excision workpiece
Produced cutting force during the allowance on surface, its Z-direction component Fz, the cutting component being consequently exerted on main shaft.Column is led
For rail, it is exactly a kind of offset loading force.It is known that amass with unbalance loading distance of offset loading force is unbalance loading moment.As shown in Figure 5: Z
Axis rail is 450mm to the distance of the alignment of shafts, and this is with regard to the unbalance loading distance of little Huang machine, and this distance is bigger.And Z axis in Fig. 6
Guide rail is the least to the distance of the alignment of shafts, 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 unbalance loading moment of the present utility model.Unbalance loading moment (is turned round
Square) computational methods see below:
1, torque arithmetic: Nz=Fz × L
The medium and small yellow machine of Fig. 5: Nz=Fz × 450
Machining center of the present utility model in Fig. 6: Nz=Fz × 60
2, comparing result: in the case of operating force is identical, it is new that the moment of torsion that little Huang machine Z axis guide rail bears is about this practicality
7.5 times of type machining center.
Shown the unbalance loading moment of main spindle box of the present utility model by above-mentioned calculating, bore Milling Machining center main much smaller than tradition
The unbalance loading moment of axle box.Unbalance loading moment is the source of main tank vibration, and the vibration adding man-hour can be along with process velocity, the increase of operating force
And increase.Amplitude can directly influence the service life of guide rail, main shaft bearing, lathe rigidity and processing characteristics.For carrying further
The rigidity of high main spindle box, headstock structure of the present utility model uses similar ram type high rigidity main shaft used by large-sized gantry machine
Box structure, its good rigidly, can bear higher rotating speed, and processing characteristics also has and is greatly improved.
To sum up, this utility model elbow column bores Milling Machining center, by being provided with an elbow in inverted L shape on lathe bed
Column, and form concave installation groove at the elbow part of elbow column, detachably connectable fixed main shaft in groove is installed
Case, installs and is respectively fixed with a line rail slide block on two sidewalls of groove, and the position of main spindle box homologous pair rail slide block is fixed with
One linear guides that can arrange along Z-direction, can make main spindle box be clamped in peace by line rail slide block with coupling of linear guides
In dress groove and plummet can be made along its center of gravity direction and move.This utility model elbow column bores Milling Machining center, is different from tradition
Bore the right cylinder that Milling Machining center is used, use elbow column can reduce unbalance loading moment and overhanging moment to greatest extent to master
Axle box kinematic accuracy, static accuracy and and machining accuracy impact so that main spindle box can in the case of zero cantilever moment,
Along vertical high-speed cruising, solve main spindle box thus some cantilever moments caused the problem of bowing of main spindle box, main spindle box
Equilibrium problem, well solve oscillation phenomenon during main spindle box high-speed cruising.
Although description of the present utility model being combined embodiments above carry out, but, it is familiar with the art
Personnel can carry out many replacement, modifications and variations according to above-mentioned content, be apparent from.Therefore, all such
Substitute, improve and change in the spirit and scope being included in appended claims.
