Summary of the invention
The purpose of this utility model is to provide a kind of axial step-by-step movement vibration turning device, allows lathe tool do the mandatory swing of step-by-step movement to a direction, compares with conventional reciprocating formula vibration turning, has reduced the friction of cutter and finished surface, has improved cutter life.
The technical scheme that the utility model adopted is, axial step-by-step movement vibration turning device, comprise base, base is provided with the vibration casing, be provided with one by motor-driven vibrating shaft in the vibration casing, fix an eccentric cam on the vibrating shaft, eccentric cam and vibrating shaft are formed double eccentric mechanism, in the vibration casing, with the perpendicular vibrating shaft that also is provided with of the axis of vibrating shaft, be provided with sliding bearing between vibrating shaft and the casing, an end of vibrating shaft contacts with eccentric cam by roller, and the other end withstands on and is arranged on the outer tool holder of casing, the axis and the vibrating shaft of tool holder are perpendicular, one end of tool holder is swung around the shaft, and rotating shaft is fixed on the base, and the other end of tool holder is fixed with lathe tool.
Characteristics of the present utility model are that also on the base, tool holder also is provided with the flat bearing slide block near lathe tool one end place, is used for the support of tool holder, and bears cutting force.
Vibration turning device of the present utility model is compared with traditional reciprocating vibration cutting mechanism has outstanding advantage:
(1) saved the backswing mechanism of lathe tool, compact conformation;
(2) lathe tool has the impact effect of vibrocutting, and cutting force is descended, simultaneously can chip breaking, reach the purpose of control length of chip;
(3) owing to there is not the cutter backswing, the wearing and tearing of lathe tool are cut less than reciprocating vibration, so improve the service life of cutter greatly.
The utility model can be used as a functional part of lathe, does not destroy existing machine tool structure, and easy to use, it is rough turn effective, and especially the rough turn processing in the automatic production line has important use value.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.
Reciprocating vibration turning, its turning mechanism are that lathe tool is done enforceable double vibrations (swing), and as can be seen, cutter also has the backswing campaign except having ballistic motion forward in cutter path figure shown in Figure 1, and promptly lathe tool is done reciprocating type swing.
And step-by-step movement vibration turning of the present utility model only needs lathe tool to do mandatory swing to a direction.As can be seen, cutter has only ballistic motion forward from cutter path figure shown in Figure 2, does not have the backswing campaign, and promptly lathe tool is only to a direction swing (along the direction of feed swing).
Realize above-mentioned turning mechanism, an embodiment of the organization plan that the utility model adopts as shown in Figure 3.In the casing 2, vibrating shaft 5 is bearing on the casing 2 by pair of bearings 4, vibrating shaft 5 is driven by motor 1, fix an eccentric cam 3 on the vibrating shaft 5, eccentric cam 3 is formed double eccentric mechanism with vibrating shaft 5, in the casing 2, with the perpendicular vibrating shaft 8 that also is provided with of the axis of vibrating shaft 5, be provided with sliding bearing 7 between vibrating shaft 8 and the casing 2, vibrating shaft 8 is by sliding bearing 7 guiding, and an end of vibrating shaft 8 contacts with eccentric cam 3 by roller 6, the other end withstands on the tool holder 13 that is arranged at outside the casing 2, the axis of tool holder 13 and vibrating shaft 8 are perpendicular, and an end of tool holder 13 is around rotating shaft 15 swings, and the other end of tool holder 13 is fixed with lathe tool 9.Casing 2, motor 1, rotating shaft 15 all are fixed on the base 14, and on the base 14, tool holder 13 is used for the support of tool holder 13, and bears cutting force near the following flat bearing slide block 12 that also is provided with of lathe tool one end.
