A part connects into an entirety, and keeps a kind of connection method of mutual alignment.It is low with light weight and cost, technique is simple
Just the advantages that.The staking bar of existing staking equipment be monolithic construction (referring to figure 1, figure 2 and figure 3), by department of assembly 10 and with
The threaded shank 11 of one entirety is constituted.When staking, by staking bar assembly in staking equipment, and the threaded shank 11 made and staking
The rivet nut of equipment is cooperatively connected, and can carry out staking.In use, staking bar is easy to happen abrasion, is vulnerable part, at present
When replacement, can only integral replacing, and need external buying, procurement cycle is long, and higher cost.Accordingly, there exist improved demands.
" a kind of full autocontrolled pneumatic riveting gun for riveting nut " disclosed in CN 2288030, main composition include gun body, top
Cap, staking bar and the piston being arranged on staking bar and the reverse motor being located above piston and be located at below piston can
Motor is rotated forward in axial sliding along staking bar, rotates forward motor and piston constitutes a closed air cavity, one is provided in gun body to be connected to
The airflow channel of the closed air cavity and reverse motor is additionally provided with a return spring between motor and gun body rotating forward.High pressure gas is first
So that staking bar is rotated forward to screw in after riveting nut then act on piston and be allowed to lift and is imposed pulling force to staking bar, completes riveting, then
Reversion staking bar exit riveting nut, can a gas complete riveting nut staking operation.But it is not involved with and how to improve staking
The problem of rod structure.
Summary of the invention
The purpose of the utility model is to provide a kind of split type staking bar, can be replaced after threaded rod abrasion, assembly head
It is reusable, it not only can be shortened the replacement cycle, but also maintenance cost can also be reduced.
A kind of split type staking bar described in the utility model, including assembly head, it is characterized in that: the assembly head and a pair of
The one end fits connection of head screw rod, the other end of a double threaded screw and the rivet nut of staking equipment are cooperatively connected.
Further, the left part of the assembly head is horizontal short cylindrical, right part is the frustum of a cone, in the assembly head in
Center portion position is equipped with pilot hole and therewith with the assembly head threaded hole of center line, which penetrates through the assembly head right part
The frustum of a cone；Only head thread hole before and after the middle part of the assembly head is equipped with perforation；The left part of the double threaded screw is equipped with dress
Rivet nut matching thread is equipped with head matching thread, right part；The assembly head matching thread of the double threaded screw left part with it is described
Assembly head threaded hole is cooperatively connected, and is locked with a locking nut.
It further, further include an only head screw, the only head thread hole cooperation in the middle part of only head screw and the assembly head
Connection.
The utility model has the beneficial effects that
Since for split type structure, assembly head may be reused, and can voluntarily process, process equipment require it is low,
Period is short, at low cost；Since double threaded screw is high-strength bolt and locking nut is commercially available standard component, at low cost, procurement cycle
It is short；Due to that can be replaced after double threaded screw abrasion, and it is convenient and efficient.Split type staking bar assembly is easy, may be implemented to replace completely
For original-pack component.

Specific embodiment
The utility model will be further described with reference to the accompanying drawing.
Referring to fig. 4 to Figure 12, a kind of split type staking bar, including assembly head 20, it is characterized in that: the assembly head
It is connect with the one end fits of a double threaded screw 30, the other end of a double threaded screw 30 and the rivet nut of staking equipment cooperate
Connection.
The left part of the assembly head 20 is horizontal short cylindrical, right part is the frustum of a cone, the center in the assembly head 20
Position is equipped with pilot hole 21 and therewith with the assembly head threaded hole 22 of center line, which penetrates through the assembly head 20
The frustum of a cone of right part；Only head thread hole 23 before and after the middle part of the assembly head 20 is equipped with perforation；The double threaded screw 30
