In addition, in order to improve working (machining) efficiency and to improve precision and the uniformity of the 4 chamfered edge processing of tooth top limit, preferably, as illustrated in fig. 1 and 2, gear machining equipment of the present utility model also includes chamfered edge guide 11, this chamfered edge guide 11 has the first guide body 12, moves to its chamfered edge position and start to carry out chamfered edge to add man-hour at described gear 2 from its desired location, and described the first guide body 12 contacts the side 14 of the tooth 13 of described gear 2 in the time of described gear 2 rectilinear motion.
As shown in Figure 1,2 and 3, take gear 2 as example as helical gear, fixture 1 driven gear 2 moves to its chamfered edge position from desired location, now, the first guide body 12 is by the side 14 of the described helical gear tooth 13 of contact, cutter 3 acts on the tooth top limit 4 of other teeth of gear, like this, fixture 1 driven gear is in the central axial direction of gear upwards when rectilinear motion, cutter 3 will carry out chamfered edge processing to tooth top limit 4, because the first guide body 12 contacts side 14, will order about gear and correspondingly rotate simultaneously, thereby realize the chamfered edge processing lasting to helical gear.After tooth top limit 4 chamfered edges, fixture 1 moves to desired location by driven gear 2 from chamfered edge position, to carry out chamfered edge processing next time.
In the time that described gear 2 is spur gear, the contacts side surfaces of the same tooth with described spur gear of the first guide body 12, gear is carried out to good guiding function when rectilinear motion on heart axis direction therein at described spur gear, to realize accurate with consistent chamfered edge processing.Now, the first guide body 12 will not ordered about spur gear and be rotated, correspondingly, gear 2 during for spur gear described in gear machining equipment will comprise the rotary drive mechanism (not shown) that drives described spur gear to carry out corresponding rotation at described desired location.
Further, in order to realize the guiding effect better to gear, preferably, as shown in Figure 2, described chamfered edge guide 11 also comprises and spaced the second guide body 15 of described the first guide body 12, adjustable interval between described the first guide body 12 and described the second guide body 15, and contact with two described sides 14 of the same described tooth 13 of described gear 2 respectively.Like this, by adjusting the spacing between described the first guide body 12 and described the second guide body 15, can adapt to different tooth pitches, simultaneously, the tooth of gear will enter into spacing between described the first guide body 12 and described the second guide body 15, thereby in the time that gear is helical gear, more stably drive helical gear to rotate, or in the time that gear is spur gear, guide more well the movement of spur gear.
Further, as shown in Figure 2, described the first guide body 12 is formed with respectively with described the second guide body 15 the first spheroid 16 and the second spheroid 17 that contact with described side 14, by being slidably matched of spheroid and face, can realize better guiding function.
In addition, as shown in Figure 1, described chamfered edge guide 11 also comprises support plate 18 and is fixed on the guide body mount pad 19 on this support plate 18.For example, as shown in Figure 1, on guide body mount pad 19, be formed with installing space, described the first guide body 12 and described the second guide body 15 stack gradually and are arranged in this installing space, and the first spheroid 16 and the second spheroid 17 are respectively formed at described the first guide body 12 and described the second guide body 15 on the side surface of gear.
Further, the free degree that fixture 1 driven gear carries out on both direction can realize by following structure, particularly, as shown in Figure 1, described fixture 1 is fixedly connected on the output of vertical cylinder 20, described vertical cylinder 20 is fixedly mounted on slide unit 21, and described slide unit 21 is slidably arranged on horizontal guide rail 22 and is connected in horizontal air cylinder 23, and described slide unit 21 is connected with stroke limit piece 26.
Like this, fixture 1, under the effect of vertical cylinder 20 and horizontal air cylinder 23, can be realized moving both vertically and horizontal movement of gear, as shown in Figure 3, meanwhile, the horizontal movement of gear will be subject to the constraint of stroke limit piece 26, thereby specifically adjusts according to the gear of the different numbers of teeth of different moduluses.
Further, in order to realize the structural compactness of this gear machining equipment, as shown in Figure 1, described horizontal guide rail 22 and described slide unit 21 are positioned at a side of described support plate 18, described horizontal air cylinder 23 is positioned at the opposite side of described support plate 18, and the output of described horizontal air cylinder 23 passes the opening 24 being formed on described support plate 18 to be connected with described slide unit 21.
In addition, as shown in Figure 1, described gear machining equipment also comprises installing plate 25, and whole mechanisms described above and parts are arranged on this installing plate 25.
The operation principle that describes a kind of embodiment of the utility model gear machining equipment below in conjunction with Fig. 1-3 in detail take gear 2 as example as helical gear:
In the time that vertical cylinder 20 drives gear to be processed 2 to move vertically upward in described chamfered edge position, the first guide body 12 will contact respectively in the helical gear teeth groove of threading and with two sides of same tooth with the second guide body 15, to force helical gear rotation when helical gear moves vertically upward, now just realize points all on the tooth top limit motion of spinning, meanwhile, on the emery wheel of fixed position rotation just can be to a tooth top limit, all points carry out grinding.When completion of processing one whole piece tooth top limit, helical gear will move upward to limes superiors position, then under the effect of horizontal air cylinder 23, do horizontal movement, away from the first guide body 12 and the second guide body 15 and emery wheel (as shown in Figure 3), and then do vertically downward and move, and then do again horizontal return movement, arrive described desired location.Now, due to the guiding function of the first guide way and the second guide way, processed helical gear has rotated certain angle around self central axis, if now this helical gear moves vertically upward again, to enter next circulation, so, the first guide way and the second guide way by just thread with teeth groove is adjacent before next teeth groove in (namely, the first guide way and the second guide way be two contacts side surfaces of the tooth adjacent with the next one just), like this, emery wheel just can carry out grinding to next tooth top limit.Circulation successively, until the processed corner angle in whole tooth top limits.
Below describe by reference to the accompanying drawings preferred embodiment of the present utility model in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
In addition, between various embodiment of the present utility model, also can be combined, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
