Three-axis numerical control gear chamfering machine with automatic tooth mesh device
Technical field
The utility model belongs to the gear cutting machine field, relates to a kind of three-axis numerical control gear chamfering machine with automatic tooth mesh device.
Background technology
At present, gear chamfering machine adopts chamfered edge cutter mode initiatively more, and in the gear chamfering machine that adopts this scheme, pillar is installed in the rear of workpiece box, adopts the structure mounting cutter of cantilever beam, and its rigidity is relatively poor; Main motor is installed on the pillar and drives the chamfered edge cutter and is rotated, be about to cutter shaft as driving shaft, because the restriction of drive system structure, also can cause the mobile range of chamfered edge cutter and burring knife less, generally be merely able to about mobile 10mm, the tool changing operation complexity is unsuitable for the conversion processing work.In addition, also need the workman workpiece to be installed on the workpiece box during card engaging workpiece with hand, and by manually the teeth groove and the chamfered edge cutter of gear being aligned, if this moment, lathe started suddenly because of some unexpected factor, because the close together of chamfered edge cutter, burring knife and workpiece, therefore be easy to and even workman's hand arm is involved in, cause serious industrial accident.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of good rigidity, chamfered edge cutter and burring knife displacement range big, with automatic tooth mesh device, tool changing and card engaging workpiece handy and safe be applicable to production line use the three-axis numerical control gear chamfering machine.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of three-axis numerical control gear chamfering machine of production line with automatic tooth mesh device, comprise lathe bed, it is characterized in that: the lathe bed front portion is equipped with left Z axis rail and right Z axis rail, on the Z axis rail of a left side workpiece box is installed, be equipped with on the workpiece box in order to drive the Z axle servomotor of workpiece rotation, on the right Z axis rail tailstock is installed, the postmedian of lathe bed upper surface is equipped with the X-axis knife rest by the X-axis guide rail, be coated with the chamfered edge cutter by chamfered edge cutter main shaft on the X-axis knife rest, X-axis guide rail rear is equipped with the X-axis servomotor that is used to drive the X-axis knife rest, X-axis guide rail both sides are equipped with column, by the Y-axis guide rail Y-axis knife rest is installed in the middle of the column, be coated with burring knife by the burring knife main shaft on the Y-axis knife rest, Y-axis guide rail rear end also is equipped with the Y-axis servomotor that is used to drive the Y-axis knife rest.
X-axis servomotor and Y-axis servomotor have the active force measuring ability.With the X-axis servomotor is example, when chamfered edge cutter during in tool setting, in case the tooth top of chamfered edge cutter contacts with the tooth top of gear, cause that the chamfered edge cutter can't descend, tool setting is not in place, then the electric current in the X-axis servomotor can increase, and after this signal was transferred to control system, the X-axis servomotor drove the X-axis knife rest and upwards returns, drive the work spindle rotation by Z axle servomotor, gear is rotated transverse tooth thickness half.Then when the X-axis servomotor drives the downward tool setting of X-axis knife rest once more, the chamfered edge cutter can descend smoothly and put in place then, and the tooth portion of chamfered edge cutter enters in the teeth groove of gear and finishes the tool setting action.
Advantage and the good effect that the utlity model has are: in the utility model, on the pillar at lathe rear portion, the Y-axis knife rest is installed by the Y-axis guide rail, improved the installation rigidity of chamfered edge cutter, utilize servomotor drive Y-axis knife rest and X-axis knife rest respectively along Y-axis and X-axis guide rail movement, both displacement range have significantly been improved, for card engaging workpiece and replacing cutter provide convenience.In addition, the utility model has also possessed the function of automatic tool preset, need not when making material loading manually workpiece to be machined and chamfered edge cutter to be meshed, feed mechanism only need be placed to workpiece on the work spindle and get final product, and has reduced the task of the automatic feed mechanism of automatic production line; The safe coefficient of raising system has guaranteed workman's handling safety, is convenient to the popularization of gear numerical control chamfering machine on automatic production line.

The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1-Fig. 2, a kind of three-axis numerical control gear chamfering machine with automatic tooth mesh device, comprise lathe bed 1, it is characterized in that: lathe bed 1 front portion is equipped with left Z axis rail 2 and right Z axis rail 5, on the left side Z axis rail 2 workpiece box 3 is installed, be equipped with on the workpiece box 3 in order to drive the servomotor 4 of workpiece 18 rotations, on the right Z axis rail 5 tailstock 6 is installed, the postmedian of lathe bed 1 upper surface is equipped with X-axis knife rest 8 by X-axis guide rail 7, be installed with chamfered edge cutter 17 by chamfered edge cutter main shaft 16 on the X-axis knife rest 8, X-axis guide rail 7 tops are equipped with the X-axis servomotor 9 that is used to drive X-axis knife rest 8, X-axis guide rail 7 both sides are equipped with column 10, by Y-axis guide rail 11 Y-axis knife rest 12 is installed in the middle of the column 10, be coated with burring knife 15 by burring knife main shaft 14 on the Y-axis knife rest, Y-axis guide rail rear end also is equipped with the Y-axis servomotor 13 that is used to drive Y-axis knife rest 12.
Operating principle of the present utility model is as follows:
See also Fig. 3, rotatablely moving of servomotor 4 transmitted on the workpiece 18, workpiece 18 rotations, and workpiece 18 drives chamfered edge cutter main shaft 16 and 14 rotations of burring knife main shaft by the engagement with chamfered edge cutter 17 and burring knife 15, finishes chamfered edge and deburring operation.
X-axis servomotor and Y-axis servomotor have the active force measuring ability.With the X-axis servomotor is example, when chamfered edge cutter during in tool setting, in case the tooth top of chamfered edge cutter contacts with the tooth top of gear, cause that the chamfered edge cutter can't descend, tool setting puts in place, then the electric current in the X-axis servomotor can increase, after this signal is transferred to control system, the X-axis servomotor drives the X-axis knife rest and upwards returns, drive the work spindle rotation by Z axle servomotor, gear is rotated transverse tooth thickness half, then when the X-axis servomotor drove the downward tool setting of X-axis knife rest once more, the chamfered edge cutter can descend smoothly and put in place, and the tooth portion of chamfered edge cutter enters and finishes the tool setting action in the teeth groove of gear.
