Description

A kind of split type staking bar
Technical field
The utility model relates to hand riveters, and in particular to a kind of split type staking bar.
Background technique
Riveting technology is one of advanced interconnection technique in the world today, it is widely used in container, household electrical appliances, garage The fields such as industry, aerospace.Riveting is by mechanical, physics and chemical method, and metallurgical mode will be more using axial force 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 Left part is equipped with assembly head matching thread 31, right part is equipped with rivet nut matching thread 32;The assembly of 30 left part of double threaded screw Head matching thread 31 and the assembly head threaded hole 22 are cooperatively connected, and are locked with a locking nut 40.
The split type staking bar, further includes an only head screw 50, in only head screw 50 and the assembly head 20 The only head thread hole 23 in portion is cooperatively connected.
The assembly head using center lathe can machine-shaping, can voluntarily be processed using unit, process equipment requirement Low, the period is short, at low cost;The double threaded screw is high-strength bolt and locking nut is commercially available standard component, and procurement cycle is short, at This is low.
In use, referring to Figure 13 to Figure 15, by the dress on the left end of the double threaded screw 30 of double end high intensity and assembly head 20 It is cooperatively connected with head thread hole 22, and is limited with limit screw cap 40;Split type staking bar is packed into hand riveter 60 again, is used Only the positioning of head screw 50 is locked;Then, the rivet nut of staking equipment and the rivet nut of 30 right part of double threaded screw are cooperated into spiral shell Line 32 is cooperatively connected, and place can carry out staking.
The split type staking bar alternative original-pack monoblock type staking bar completely, and different rule can be selected according to actual needs The threaded rod of lattice realizes the substitution to various specifications staking bar.
