Move top service life.
Detailed description of the invention
In order to keep the purpose of this utility model, technical scheme and beneficial effects clearer, the utility model provides as follows
Attached drawing is illustrated:
Fig. 1 is structure sectional view of the utility model for the rolling center of hobboing cutter teeth.
Fig. 2 is quill cross-sectional view of the utility model for the rolling center of hobboing cutter teeth.
In figure, 1 is tailstock sleeve, and 2 be quill, and 3 be bearing, and 10 be internal taper hole, and 21 be top section, and 22 be interlude,
23 be linkage section, and 24 be interior circular hole, and 25 be conical bore, and 4 be nut, and 5 be end cap.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art
The utility model can be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
As shown in Figure 1, a kind of rolling center for hobboing cutter teeth of the utility model, including tailstock sleeve 1 and quill
2, quill 2 is set in tailstock sleeve 1 and keeps coaxial.If being equipped with dry bearing 3, sleeve between tailstock sleeve 1 and quill 2
Axis 2 is mounted in bearing 3.When tailstock sleeve 1 is fixed, when quill 2 is by all outward forces, quill 2 is turned centered on axis
It is dynamic.It is equipped with internal taper hole 10 in the one end of quill 2 connecting with mandrel to be processed, the cross sectional shape of internal taper hole 10 is trapezoidal,
Taper is 1:5.In use, there is mandrel the top needle of raised type to be plugged in internal taper hole 10, stationary center sleeve 1 works as mandrel
