Embodiment Construction
[0017] The present invention will be further described below in conjunction with drawings and embodiments.
[0018] Such as Figure 1 ~ Figure 4 As shown, the present invention includes a positioning mechanism 1 and a locking mechanism 2. The positioning mechanism 1 includes a positioning tire 10 and a center-through seat 20. The positioning tire 10 of this embodiment is a stepped circular part, and one end thereof is fixed on a lathe fixture 5 The other end is embedded in the inner hole 110 at the bottom of the piston 100 . Piercing seat 20 is a cuboid, and its bottom both sides are fixed on the center of positioning round table 11 of positioning tire 10 by 6 fastening screws, and a rectangular cross hole 201 perpendicular to the axis of threading seat is provided in the middle of threading seat 20 . The locking mechanism 2 includes an elastic clamping mechanism 21, a screw propulsion mechanism 22, and a horizontal pin 23. The horizontal pin 23 is a long shaft member with an...
