Detailed description of the invention
The present invention is described in detail below in conjunction with the accompanying drawings.
The structure of the quick-release type spherical centering mandrel that the present invention provides is as it is shown in figure 1, this device spherical centering mandrel 1, fast
Relief panel 2 and clamp nut 3.
As in figure 2 it is shown, spherical centering mandrel 1 is multidiameter, spherical centering mandrel by first shaft part the 5, second shaft part 6,
Three shaft part the 7, the 4th shaft part 8 and the 5th shaft parts 9, first shaft part the 5, second shaft part the 6, the 5th shaft part the 9, the 3rd shaft part the 7, the 4th shaft part
8 sequentially coaxially connect and for integral type structure.Second shaft part 6 is in billiard table shape, and the diameter of the first shaft part 5 is less than the second shaft part 6
Minimum diameter, the diameter of the 5th shaft part 9 is not more than the maximum gauge of the second shaft part 6, and the diameter of the 3rd shaft part 7 is more than the second shaft part
The maximum gauge of 6.It should be noted that the second shaft part and the axial height of the 3rd shaft part are not more than thin-walled sphere cylinder class zero herein
The height of part, and shape, the size of the shape of the second shaft part, size and thin-walled sphere tube kind part inwall match.
As it is shown on figure 3, fast relief panel 2 is in the form of annular discs, fast relief panel 2 end face is provided with nut counterbore 13, fast relief panel 2 edge
Radially offering U-shaped groove 10, U-shaped groove 10 is made up of semicircle groove 11 and square three-way groove 12, and semicircle leads to the straight of 11 grooves
The width that footpath is constituted with square three-way groove 12 is identical.Owing to there being U-shaped groove, can be fast by U-shaped groove after unscrewing locking nut
Speed is installed and fast quick-detach.Semicircle groove 11 is provided with female thread.The diameter of semicircle groove is slightly less than the straight of the first shaft part
Footpath, the diameter 2mm less than the diameter of the first shaft part of general semicircle groove, it is ensured that fast relief panel is sleeved on spherical centering core smoothly
On axle.
Fast relief panel 2 is sleeved on the first shaft part 5 by U-shaped groove 10, and by clamp nut 3 and nut counterbore 13
Coordinate fixing, fast relief panel 2 and the first shaft part 5 matched in clearance.
The using method of this quick-release type spherical centering mandrel is as follows:
