Abstract
The title of the utility model is that set is drawn in a kind of assembly of hydraulic cylinder piston rod, is related to a kind of for assembling the tooling of hydraulic cylinder piston rod.The problem of it mainly solves a little bias in hydraulic cylinder piston rod assembling process or collides with to will lead to hydraulic cylinder cylinder barrel or piston rod seal component scuffing or damaged, influences the air-tightness of hydraulic cylinder seal chamber, hydraulic oil is caused to be revealed, and hydraulic cylinder is scrapped.The set that draws of the utility model is combined into a cylinder by two semicircular cylinder groups, and the outer circle of cylinder one end is equipped with step, and outside diameter B and the cylinder tube head outside diameter of the other end of cylinder match, and draws circular diameter A in set and matches with circular diameter in cylinder tube.When the utility model is used, cylinder tube head is placed in the end for drawing set, and piston rod is arranged with one end of round and smooth chamfering and is filled in into cylinder tube by drawing；When the utility model can be such that hydraulic cylinder piston rod assembles, colliding in piston rod assembling process and deviation are avoided, guarantees the air-tightness of hydraulic cylinder seal chamber.
Description
Technical field
The utility model relates to a kind of assembly of hydraulic cylinder piston rod to draw set, relate particularly to a kind of hydraulic for assembling
The tooling of cylinder piston rod.
Background technique
Hydraulic cylinder piston rod assembly is a critical process of hydraulic cylinder production, is applicable in currently without dedicated tooling
The guiding and positioning of piston rod in assembling process, operator use a little bias positioned by hand, during equipping or knock
It touches and will lead to hydraulic cylinder cylinder barrel or piston rod seal component scuffing or damaged, influence the air-tightness of hydraulic cylinder seal chamber, lead
Hydraulic oil leakage is caused, hydraulic cylinder is scrapped.There is a kind of large-scale positioning device, price is high and volume is big, inconvenient to use.
Summary of the invention
The purpose of this utility model be in view of the above-mentioned deficiencies, and propose one kind hydraulic cylinder piston rod can be made to assemble
When, colliding in piston rod assembling process and deviation are avoided, guarantees the air-tightness of hydraulic cylinder seal chamber, avoids the occurrence of hydraulic oil
Set is drawn in leakage, and the hydraulic cylinder piston rod assembly for avoiding hydraulic cylinder from scrapping phenomenon.
The technical solution of the utility model is: draws set by two semicircular cylinder groups and is combined into a cylinder, cylinder one end
Outer circle is equipped with step, and outside diameter B and the cylinder tube head outside diameter of the other end of cylinder match, and draws circular diameter in set
A matches with circular diameter in cylinder tube.
Draw one end inner circle for being arranged with step described in the technical solution of the utility model equipped with transition chamfering.
Draw between two semicircular cylinders of set that there are clearance Cs described in the technical solution of the utility model.
When the utility model is used, cylinder tube head is placed in the end for drawing set, and piston rod is arranged with round and smooth chamfering by drawing
One end fill in into cylinder tube, after piston rod is fully inserted into cylinder tube, drawing set can be removed, finally sealed oil cylinder
Cylinder barrel；When the utility model can be such that hydraulic cylinder piston rod assembles, colliding in piston rod assembling process and deviation are avoided, is protected
The air-tightness for demonstrate,proving hydraulic cylinder seal chamber avoids the occurrence of hydraulic oil leakage, and hydraulic cylinder is avoided to scrap.
Detailed description of the invention
Fig. 1 is the main view of the utility model.
Fig. 2 is the right pseudosection of Fig. 1.
Specific embodiment
As shown in Figure 1, 2, the set that draws of the utility model is combined into a cylinder by two semicircular cylinder groups, between two semicircular cylinders
There are clearance C, the outer circle of cylinder one end is equipped with step 1, makes to draw set along axial cross section in a T shape；Draw set 2 outer circle of the other end
Diameter B size match with cylinder tube head inner circle diameter dimension, draw diameter of a circle A size and cylinder tube inner circle in covering
Diameter dimension matches, in use, cylinder tube head is placed on the end for drawing set；One end inner circle equipped with step 1 is equipped with
Rounding off chamfering 3, the outer end side of chamfering is 30 °, and interior end side is 15 °, which draws for guiding piston rod to enter
Set draws in set in use, piston rod is entered by the one end for being equipped with transition chamfering 3；The internal circular surfaces for drawing set are shiny surface, facilitate work
Stopper rod, which enters, draws set the inside.
Working principle: in use, the set that draws of the utility model is covered in cylinder tube inlet, step 1 is in cylinder tube head
The other end 2 of set is drawn embedded in cylinder tube head, as shown in Figure 2 in outside；Cylinder tube, which is affixed to, to be drawn set to be not provided with step 1 another
On the end face at end 2, draw in the plane that set inner wall is maintained at same with cylinder tube inner wall, draws set outer wall and cylinder tube head
Size matches, and piston rod is filled in from the round and smooth chamfering 2 for drawing set draws set the inside, and piston rod fills in oil cylinder by drawing set inner hole
Cylinder, after piston rod is fully inserted into cylinder tube, removes and draws set, finally sealed cylinder tube.
Claims (3)
1. set is drawn in a kind of hydraulic cylinder piston rod assembly, a cylinder, cylinder are combined by two semicircular cylinder groups it is characterized in that: drawing set
The outer circle of one end is equipped with step (1), and outside diameter B and the cylinder tube head outside diameter of the other end (2) of cylinder match,
Draw circular diameter A in set to match with circular diameter in cylinder tube.
2. set is drawn in a kind of hydraulic cylinder piston rod assembly according to claim 1, it is characterized in that: described drawing is arranged with platform
One end inner circle of rank (1) is equipped with transition chamfering (3).
3. set is drawn in a kind of hydraulic cylinder piston rod assembly according to claim 1, it is characterized in that: two for drawing set
There are clearance Cs between semicircular cylinder.
