Abstract
The utility model relates to a device for processing a spiral bevel gear by four-axis processing center, comprising a positioning seat, a fourth axis base, a fourth axis, a cutter disc and a cutter disc spindle, wherein the fourth axis base is arranged on the positioning seat and moves on all sides, the fourth axis is arranged on the fourth axis base and can move on all sides, the cutter disc is arranged on the fourth axis and corresponds to a workpiece on the fourth axis, and the cutter spindle is used for fixing the cutter disc and adjusting the position of the cutter disc. The device has low cost.
Description
Technical field
The utility model relates to the device of four Cutter Body Processing with Machining Center spiral bevel gears of a kind of usefulness, particularly processes the device of Gleason spiral bevel gear.
Background technology
In the prior art, the tooth Profile Machining of gear with curved teeth bevel gear all is to use special-purpose spiral bevel gear to mill (mill) tooth machine.Basic structure and movement relation are shown in accompanying drawing 2.
Certain existing numerical control gear cutting machine such as Gleason phoenix machine series etc., its cage chair motion is accomplished through the numerical control interpolation by diaxon, and other motion and structure are identical substantially, but importantly these lathes all are special-purpose lathes.
Summary of the invention
It is low that the technical problem that
the utility model will solve provides a kind of cost, the device of four Cutter Body Processing with Machining Center spiral bevel gears of usefulness of the good product quality of production.
The content of
the utility model is, comprise positioning seat, be arranged on the 4th base that can move on the positioning seat all around, be arranged on the 4th base can move the 4th all around, be arranged on the 4th top with the 4th on the corresponding cutterhead of workpiece and be used for fixing cutterhead and the cutter spindle of adjustment cutterhead position.
the invention has the beneficial effects as follows, the utility model is not needed motion and a movement relation in the time of will changing original Gear Processing.And according to utilizing four existing conditions of machining center, concern through the relative mounting positions that changes original workpiece, cutter, and utilize the facility of Numeric Control Technology for each motion control, satisfy the required movement relation of Machining of Gear under the condition of reposition relation.Specify relative position relation and movement relation (with former method corresponding one by one) below.
Below be explanation to accompanying drawing 2:
The adjustment relation of 1 position of wheel and cutter spacing:
The eccentric angle adjustment that does not show among
V (workhead offset adjustment), H (adjustment of horizontal position of wheel), G (root angle adjustment) and the figure.
Several just are used to adjust the wheels position relation relative with cutter spacing more than
, in case get off really, are no longer moving in process.
2 main motions:
A. cutterhead rotation
B. workpiece rotation
C. cage chair rotation
D. saddle forward-reverse
above four are only motion required in the processing, and in these four, workpiece rotation and cage chair rotation need interlock on request.
The utility model is following with the corresponding relation of Fig. 2 of prior art:
The adjustment relation of 1 position of wheel and cutter spacing
Owing to can adjust the inclination angle for the 4th that adopts, so G just is equivalent to original G (root angle)
owing to machining center, X, Y axle can be set in the optional position with zero-bit, therefore can satisfy V, the H demand in the processing.
The correspondence of 2 movement relations
What the rotation of
a. cutterhead do not have different.
I.e. the 4th the rotation of
b. workpiece rotation.
c. is in the rotation of cage chair; The utility model is to utilize the X axle of numerical control machining center and Y axle to do the circular interpolation motion; Motionless with original work spindle; Cutterhead around work spindle center rotation different be: the utility model is that the cutterhead center is motionless, and workpiece is made circular motion around cutterhead.The rotation of original cage chair be actual be exactly that circular motion is made around workpiece centre in the cutterhead center.
The forward-reverse of
d. saddle is exactly moving up and down of Z axle in the machining center of the utility model.
The explanation that
need be: in the former motion, the cage chair rotation needs to keep interlock with the workpiece spindle rotation, and this work in-process is easy to realize the i.e. interlock of X, Y, A axle through software in the heart.
The processing of spiral bevel gear has been realized through above device in
.Because the rigidity of lathe and the restriction of structure, the mill teeth of the most suitable little modulus of the utility model (≤4) and the processing of the roll flute of various gears.The precision of gear reaches as high as 5 grades of GBs.With respect to original special purpose machine tool processing, the utility model cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the prior art constructions sketch map.
in the drawings, 1 cutter spindle, 2 the 4th, 3 the 4th bases, 4 workpiece, 5 cutterheads, 6 processing works, 7 workpiece boxs, 8 rotating chassis, 9 saddles, 10 cutterheads, 11 cage chairs, 12 positioning seats.
The specific embodiment
the utility model comprises positioning seat 12, be arranged on the 4th base 3 that can move on the positioning seat 12 all around, be arranged on the 4th base 3 can move the 4th 2 all around, be arranged on the 4th 2 tops with the 4th 2 on workpiece 4 corresponding cutterheads 5 and be used for fixing cutterhead 5 and the cutter spindle 1 of adjustment cutterhead 5 positions.
shown in accompanying drawing 2, prior art the structure of Machining of Gear in comprise saddle 9, be arranged on rotating chassis 8 on the saddle 9, be arranged on workpiece box 7 on the rotating chassis 8, be used for the cutterhead 10 of the processing work 6 on the processing work case 7 and the cage chair 11 of rotating cutter-head 10.This structure all can not reach the demand of high-quality processing spiral bevel gear on location and machining accuracy.
