Abstract
The utility model discloses a milling changeover device for gear slotting machines, wherein the cutter shaft is linked with bolts through a disk spring; the tool rest is in fixed linkage with rotors; the tool shift is sliding linkage with the tool rest; rotors are positioned conjugate cams; the conjugate cams are driven by a transmission device. During downwards operating stroke of the tool shaft, the conjugate cams are positioned at long radius R, and the rotors contact the conjugate cams; when the tool shaft returns for upward operating stroke, the conjugate cams are positioned at a short radius r and the rotors part from the conjugate rams. The utility model has the advantages of stable and reliable accuracy, and can conveniently be adjusted.
Description
Technical field
The utility model relates to a kind of tool retracting conversion device for gear-shaper.
Background technology
At present, domestic various gear shapping machine mainly uses single cam, two roller cutter relieving or modes such as wedge cutter relieving, fork cutter relieving when inserting the conversion of inside and outside tooth, main deficiency is that set-up procedure is loaded down with trivial details, operating accuracy is unreliable, pinion cutter forward off-gage phenomenon often occurs.
Summary of the invention
The purpose of this utility model provides a kind of tool retracting conversion device for gear-shaper in order to overcome the shortcoming of prior art, adopts the conjugation double cam allow knife structure, has solved the overproof problem of pinion cutter forward, and has adjusted very convenient.
The purpose of this utility model is achieved in that a kind of tool retracting conversion device for gear-shaper, cutter shaft 4 connects by disk spring 6,7 and screw 5,8, tool rest 9 and roller 2 fixed connections, cutter shaft 4 slides with tool rest 9 and connects, roller 2 is between conjugate cam 1,3, conjugate cam 1,3 is driven by transmission device, when the downward impulse stroke of cutter shaft 4, conjugate cam 1,3 is positioned at long radius R place, 2 whiles of roller this moment contact with 3 with cam 1, when cutter shaft 4 made progress return, conjugate cam 1,3 was positioned at minor radius r place, and this moment, roller 2 was thrown off with cam 1 and 3.
Adopt said structure, the change of the inside and outside tooth cutter relieving of slotting direction just only need be adjusted the pine of disk spring with tight by screw, when impulse stroke, by the long radius common guarantee of two conjugate cams, during return, throw off fully by roller and conjugate cam for the forward of pinion cutter, cutter shaft is subjected to the disk spring effect, angle of pinion cutter swing is returned, and the utility model stable accuracy is reliable, and adjusts very convenient.
Description of drawings
Be described further below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
The double accompanying drawing that makes an abstract of Fig. 1.
The specific embodiment
A kind of tool retracting conversion device for gear-shaper, cutter shaft 4 connects by disk spring 6,7 and screw 5,8, and tool rest 9 and roller 2 fixed connections, cutter shaft 4 slide with tool rest 9 and connect, roller 2 is between conjugate cam 1,3, conjugate cam 1,3 is driven by transmission device, and when the downward impulse stroke of cutter shaft 4, conjugate cam 1,3 is positioned at long radius R place, 2 whiles of roller this moment contact with 3 with cam 1, when cutter shaft 4 made progress return, conjugate cam 1,3 was positioned at minor radius r place, and this moment, roller 2 was thrown off with cam 1 and 3.
During the slotting external tooth, require to press external tooth cutter relieving direction cutter relieving, screw 8 precessions this moment, compression disk spring 7, respective screws 5 screws out, unclamp butterfly spring 6, this moment, cutter shaft 4 was subjected to the pressure to external tooth cutter relieving direction, during cutter shaft 4 down-cuttings, because of roller 2 (being connected as a single entity with cutter shaft 4) is in the middle of the long radius R of two conjugate cams 1 and 3, and contact with 3 with cam 1 simultaneously, even the external force effect is arranged, cutter shaft 4 can move left and right yet, can only vertical up-or-down movement be the cutter shaft forward, when cutter shaft 4 moves to when upwards returning after the most the next, two conjugate cams 1 and 3 have gone to minor radius r by long radius R, cutter relieving roller 2 breaks away from conjugate cam 1 and 3 simultaneously, because the precession of screw 8, cutter shaft has been subjected to the pressure to external tooth cutter relieving direction in advance, so cutter shaft 4 is close to cam 1 naturally inwards, cutter shaft 4 no longer is vertically to return but swung an angle and returned during backhaul, i.e. the external tooth cutter relieving of cutter shaft.When requiring the internal tooth cutter relieving, promptly precession screw 5 allows disk spring 6 pressurizeds, and corresponding back-out screw 8 allows disk spring 7 loosen, and this moment, cutter shaft 4 was subjected to the pressure to internal tooth cutter relieving direction, just can be automatically to internal tooth cutter relieving direction cutter relieving during backhaul.
