Abstract
A kind of piston rod projection welding limited ring, piston rod is provided with limited ring, be connected by projection welding between limited ring with piston rod, piston rod is step structure, the neutral position of piston rod is provided with limited ring, piston rod top is provided with connecting end, is provided with fixing lug boss on the upside of limited ring, and fixing lug boss is positioned at the dual-side of piston rod.By projection welding, limited ring is fixed on the piston rod, the joint efficiency of limited ring and piston rod can be ensured, save preparation cost, using effect is good, can limited ring and piston rod be interconnected fast, and limited ring adopts stamping part, the cost of production of limited ring reduces, on the piston rod, thus the cost of production of the piston rod made also reduces much, ensure that limited ring working effect on the piston rod in direct welding.
Description
Technical field
The utility model relates to a kind of limit stoper, is specifically related to a kind of piston rod projection welding limited ring.
Background technique
Piston rod often applies in piston, piston can ensure the normal operation of vehicle, piston rod runs in piston, piston rod needs mounting limit device, can well the operation of control piston bar, prevent piston rod from occurring kinematic error, but the limit stoper at present on a lot of piston rod is all adopt jump ring spacing, such limit method easily makes piston rod operation be affected, manufacture the cost of piston rod, the process of preparation is comparatively complicated, have impact on the operation of the normal table of piston rod, needs to consume more cost of production.
Summary of the invention
The purpose of this utility model is to provide a kind of easy to operate, prepares simple a kind of piston rod projection welding limited ring.
The technical solution of the utility model is: a kind of piston rod projection welding limited ring, described piston rod is provided with limited ring, be connected by projection welding between limited ring with piston rod, piston rod is step structure, the neutral position of piston rod is provided with limited ring, piston rod top is provided with connecting end, is provided with fixing lug boss on the upside of limited ring, and fixing lug boss is positioned at the dual-side of piston rod.
Described limited ring is circular ring, and mutually conflicting with piston rod inside limited ring is connected, the motion of limited ring control piston bar.
Fixing lug boss on described piston rod is positioned at the neutral position of piston rod, and fixing lug boss is provided with fixed block, and fixed block abuts mutually with piston rod, and fixed block is positioned at the upper end of fixing lug boss.
Described limited ring with between piston rod by welding, limited ring is that punching press is made.
The utility model has the advantages that: by projection welding, limited ring is fixed on the piston rod, the joint efficiency of limited ring and piston rod can be ensured, save preparation cost, using effect is good, can limited ring and piston rod be interconnected fast, and limited ring adopts stamping part, the cost of production of limited ring reduces, on the piston rod, thus the cost of production of the piston rod made also reduces much, ensure that limited ring working effect on the piston rod in direct welding.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 is piston rod, 2 is limited ring, and 3 is fixing lug boss.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
A kind of piston rod projection welding limited ring, piston rod 1 is provided with limited ring 2, be connected by projection welding between limited ring 2 with piston rod 1, piston rod 1 is step structure, the neutral position of piston rod 1 is provided with limited ring 2, piston rod 1 top is provided with connecting end, fixing lug boss 3 is provided with on the upside of limited ring 2, fixing lug boss 3 is positioned at the dual-side of piston rod, limited ring 2 is circular ring, mutually conflict with piston rod inside limited ring 2 and be connected, the motion of limited ring 2 control piston bar, fixing lug boss 3 on piston rod 1 is positioned at the neutral position of piston rod, fixing lug boss 3 is provided with fixed block, fixed block abuts mutually with piston rod 1, fixed block is positioned at the upper end connecting boss, limited ring 2 with between piston rod by welding, limited ring 2 is made for punching press.
