Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As depicted in figs. 1 and 2, the utility model includes the turntable 1 being horizontally mounted, and the top surface right angle setting of turntable 1 is useful
In the expanding arbor of stationary annular blank 3, expanding arbor includes the rigid central spindle 12 being vertically welded on turntable 1 and for supporting
The mandrel 11 that rises in the endoporus of annular blank 3, rigid central spindle 12 is pyramidal structure, and the mandrel 11 that can rise is provided with and rigid central spindle
The 12 taper axis holes matched, rigid central spindle 12 is inserted in the taper axis hole for the mandrel 11 that can rise from the bottom to top, rigid central spindle 12
Upper end is fixedly connected with screw rod 8, and the screw thread position of screw rod 8 is outside the mandrel 11 that can rise, and screw rod 8 passes the mandrel that can rise from the inside to the outside
11 and nut 7, upper pushing block 10 and lower pushing block 5 are cased with, are set between rigid central spindle 12 and the taper axis hole innermost end for the mandrel 11 that can rise
Spring 4 is equipped with, spring 4 is enclosed on screw rod 8, nut 7, upper pushing block 10 and lower pushing block 5 are from top to bottom sequentially sleeved in the screw thread of screw rod 8
Portion, lower pushing block 5 is pressed in the top surface for the mandrel 11 that can rise, and upper pushing block 10 is supported on lower pushing block 5 by some steel balls 6, and nut 7 is pressed in
The top surface of upper pushing block 10.
It is connected through a screw thread between nut 7 and screw rod 8, and not by spiral shell between lower pushing block 5 and the mandrel 11 that can rise
Line is connected, and is so easy to promote lower pushing block 5 and the mandrel 11 that can rise to be axially moved by nut 7 and upper pushing block 10, be specifically avoid
The mandrel 11 that can rise rotates, it is to avoid annular blank 3 rotates and deviates axial direction caused by being rotated because of the mandrel 11 that can rise
The situation of position.
In order that ring motion can be done without dislocating centered on screw rod 8 by obtaining some steel balls 6, the lower surface of upper pushing block 10
The annular stop neck 13 for limiting steel ball 6 is provided with the upper surface of lower pushing block 5.
