By the technical solution of the utility model, the rotation feed arrangement that it adopts integrated form is integrated power transmission shaft, main shaft, cutter shaft, its structural volume is little, the transmission efficiency height, and manufacturing process is simple, low cost of manufacture, production efficiency height, can be used for various automaticity height, strongly professional lathe.
Figure of description
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As shown in Figure 1, a kind of rotation feed arrangement that is used for lathe, comprise frame 14, power transmission shaft 2, main shaft 11 and cutter shaft 12, two ends are respectively equipped with left bearing 15, right bearing 16 in the described main shaft 11, also be provided with spacer between the described bearing, be provided with in the described spacer in cutter shaft 12 present embodiments, described right bearing 16 is 2, and described 2 right bearings 16 are positioned at the position 17 of cutter shaft 12 right-hand members near cutterhead 7.Spacer between the described left and right bearing is long spacer 10, and the spacer that the excircle at described position 17 is with is short spacer 8.Described cutter shaft 12 left ends connect power transmission shaft 2 by flat key, described left bearing 15 left ends are provided with block piece 1, block piece 1 in the present embodiment is a round nut, described round nut is positioned at the junction of cutter shaft and flat key, be used for left bearing 15 axial restraints, described cutter shaft 12 right-hand members connect cutterhead 7, described main shaft 11 right-hand members are provided with the bearing gland 6 of adjusting right bearing 16 end plays, be respectively equipped with left lining 13 between the excircle at described main shaft 11 two ends and the frame 14, right lining 9, described left lining 13, right lining 9 is fixed on the frame 14, described left lining 13, the inner ring of right lining 9 is equipped with groove, be marked with lubricating oil in the groove, play lubrication, described main shaft 11 belows connect an end of feed connecting rod 5, and described feed connecting rod 5 other ends are connected with the feed cylinder 4 of axially-movable.In the present embodiment, described left and right bearing 15,16 outer rings cooperate with main shaft 11 two ends endoporus, and its inner ring cooperates with outer ring, cutter shaft 12 two ends.
During operation, electrical machine belt pulley reaches power transmission shaft 2 with power, and power transmission shaft 2 passes to cutter shaft 12 by flat key with power, cutter shaft 12 transmission cutterheads 7, thereby the rotation of realization cutterhead.
And feed cylinder 4 promotes feed connecting rod 5, and feed connecting rod 5 drives main shaft 11.Because main shaft 11 is axial restraints with the structure of cutter shaft 12, thus present embodiment round nut 1, bearing gland 6, short spacer 8, the axial restraint that long spacer 10 and left bearing 15, right bearing 16 are realized between the cutter shaft main shafts.And be marked with lubricating oil, so can realize frequent the moving between main shaft 11 and the right side, the left lining 9,13 swimmingly, i.e. frequent mobile between main shaft 11 and the frame 14 at the inner ring groove of right lining 9 and left lining 13.Thereby satisfy the frequent feed number of times of main shaft.
And main shaft 11 adopts left and right bearing 15,16 to cooperate with 12 of cutter shafts, and main shaft 11 is separated with cutter shaft 12 rotations.Thereby main shaft 11 can drive the cutter shaft 12 and the cutterhead 7 of rotation at a high speed and realize axial feed.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
