34, upper belt pulley 35, electric machine support 36 and the second motor 37, dependency structure connecting mode are not gone to live in the household of one's in-laws on getting married separately referring to the technical solution
It states.
In no magnetic clutch clamping of workpieces revolving platform composition, band buffering self locating device 18, which has been done, separately to be invented while declaring, but
It is not only to be able to achieve the automatic positioning of 17 male cone (strobilus masculinus) of taper roller with buffering self locating device 18, but also be able to achieve the progress of taper roller 17
Rotation and revolution, this point be not accommodating doubt, and with buffering self locating device 18 in be provided with interior concave arc and tooth shaft and
The tooth shaft is configured with taper hole, no magnetic clutch clamping of workpieces revolving platform of the invention meet band buffering self locating device 18 realize rotation and
Revolution, but the present invention only illustrates the structure configuration being coupled.
Need to pay attention to the following:
1, the internal taper hole of upper 8 lower end of main shaft couples with the cooperation of the male cone (strobilus masculinus) of lower 29 upper end of main shaft, and upper compression axis 9 is screwed in top board
In 7 internal screw thread, through the lower cone link of upper compression axis 9 in the taper hole of upper 8 upper end of main shaft, the upper master of such effective guarantee
Axis 8 and the central axis having the same of lower main shaft 29, last time turntable 14 and lower rotary disk 22 go up main shaft 8 under in grinding process
Main shaft 29 be it is stationary, the stability that taper roller can be overcome to be also easy to produce is poor, is easy to produce phenomena such as axial float, subtracts
The Circular Run-out Tolerance of few spherical base surface of tapered roller, improves grinding efficiency and grinding accuracy.
2, the present invention uses several bolts, several inner bolts its specifications will be depending on different connection positions, this
Those of ordinary skill in the art are said be aobvious and known common knowledge, even if being connected and fixed for some positions does not illustrate spiral shell
Bolt, but be also essential.
3, when driving the second motor 37, the second motor 37 passes through 35 → last time of 34 → upper belt pulley of belt turntable 14 → upper pressure
Lid 5 → upper ring connects the rotations such as disk 4, and last time 14 → fluted disc of turntable 3 → tooth shaft carries out rotation grinding to taper roller 17.
4, drive first motor 33 when, first motor 33 by 30 → bottom pulley of lower belt 31 → lower rotary disk 22 → under
Gland 24 → lower ring connects the equal rotation of 20 → ring flange of disk 19, and lower rotary disk 22 → band buffering self locating device 18 is to taper roller
17 carry out revolution grinding around the central axis of lower main shaft 29.
Although 5, no magnetic clutch clamping of workpieces revolving platform structure of the invention is more complicated, in addition to surrounding upper main shaft 8 and lower master
Outside the fixed not rotatable parts of axis 29, remaining part is rotatable.
