Preferably, a plurality of fixing bolt is installed to bolt hole inside screw thread, fixing bolt one end run through outer snap ring and with outer snap ring between the installation cover threaded connection.

Preferably, notches are formed in two sides of the inner wall of the outer snap ring.

Preferably, the piston rod cushion block is fixedly arranged inside the outer snap ring mounting sleeve and positioned at the end part of the piston rod.

Preferably, a clamping groove is formed in one side of the inner wall of the inner clamping ring.

Preferably, the inner wall of the outer snap ring and the outer wall of the inner snap ring are of spherical structures respectively.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses an on snap ring and the epaxial screw thread of sphere in snap ring and the sphere outside snap ring atress in the sphere was transmitted, greatly increased lifting surface area was original bearing capacity many times, greatly increased life, made the spindle nose can not split by the root easily.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-8, the present invention provides a technical solution: the utility model provides a piston rod structure based on in succession with sphere mode, includes piston rod 10 and sets up in the mounting structure 20 of piston rod 10 one end, and mounting structure 20 includes outer snap ring installation cover 21, and outer snap ring installation cover 21 one end is provided with outer snap ring 23, and a plurality of bolt hole 231 has been seted up along the circumferencial direction in outer snap ring 23 outer wall surface, and the inside joint of outer snap ring 23 has interior snap ring 24.

Further, after the inner snap ring 24 is vertically placed into a half through a designed notch 232 on the outer snap ring 23, the inner snap ring 24 is rotated to be assembled in place according to a drawing, the inner snap ring 24 and the outer snap ring 23 are assembled on the piston rod through threads, and finally a circle of fixing bolt 25 is assembled, so that when the piston rod moves forwards and backwards to work, the piston rod is tightly connected with the inner snap ring 24 through the threads, a cutter seat on the gantry shear welded below can be firmly locked, and the head of the piston rod cannot be easily broken.

Wherein, fixing bolt 25 is installed to the inside screw thread of a plurality of bolt hole 231, fixing bolt 25 one end run through outer snap ring 23 and with outer snap ring installation cover 21 between threaded connection.

Further, the piston rod 10 is tightly connected with the inner snap ring 24 through threads, so that the upper tool holder of the gantry scissors welded below can be firmly locked, and the head of the piston rod cannot be easily broken.
