Compared with prior art, the present invention has the advantages that：The auxiliary device of protrusion height of oil sprayer detection
It is the detection for meeting protrusion height of oil sprayer only to tighten a tooling bolt, is not required to intersect repeatedly make-up fixing fuel injector shoulder
Two nuts at left and right sides of pressing plate avoid, because moment unbalance causes protrusion height of oil sprayer unqualified on nut, substantially carrying
High production efficiency, reduces labor intensity.
Description of the drawings
Fig. 1 is the structure diagram of the auxiliary device of the protrusion height of oil sprayer detection of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings, the specific embodiment of the present invention is described in detail, it is to be understood that the guarantor of the present invention
Shield range is not restricted by specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " comprising " or its change
It changes such as "comprising" or " including " etc. and will be understood to comprise stated element or component, and do not exclude other members
Part or other component parts.
As shown in Figure 1, according to the specific of the auxiliary device of the protrusion height of oil sprayer of specific embodiment of the invention detection
Structure includes：Tooling bolt 1, swivel nut 2, tooling sleeve 3, steel cylinder 4, tooling pressing plate 5 and balance weight 6.Wherein, balance weight 6 is pairs of
The bottom surface of tooling pressing plate 5 is arranged on, and offers the bolt penetration hole through balance weight 6 and tooling pressing plate 5 respectively, using being mounted in advance
The stud of cylinder cap passes through the bolt penetration hole to fix the auxiliary device with two nut preloads again.The center of tooling pressing plate 5 offers
The top surface for being fixed on tooling pressing plate 5 that fuel injector perforation, the bottom end of steel cylinder 4 and fuel injector perforation are aligned.Swivel nut 2 is fixed on steel cylinder
4 tops, the lower end of tooling bolt 1 is spirally connected with swivel nut 2 to be pierced by, and tooling sleeve 3 is fixed on the lower end of tooling bolt 1.Fuel injector is pressed
It is required that in the cylinder head fuel injector hole, after the oil inlet top surface of fuel injector passes through the fuel injector perforation of tooling pressing plate 5, with tooling sleeve
Cylinder 3 abuts positioning, then with torque of the Torque wrench by technological requirement make-up tooling bolt is determined, finally measures fuel injector with dial gauge
Protrusion height.The auxiliary device of protrusion height of oil sprayer detection only tightens a tooling bolt and meets fuel injector protrusion height
The detection of degree is not required to intersect two nuts at left and right sides of the pressing plate for repeatedly tightening fixing fuel injector shoulder, avoids because on nut
Moment unbalance causes protrusion height of oil sprayer unqualified, and production efficiency greatly improved, and reduces labor intensity.
Specifically, the center of tooling pressing plate 5 offers fuel injector perforation, and the both sides of fuel injector perforation offer the respectively
One bolt penetration hole, for fuel injector as required in cylinder head fuel injector hole, the oil inlet top surface of fuel injector passes through the spray of tooling pressing plate 5
Oily device perforation.Balance weight 6 is arranged in pairs in below the first bolt penetration hole of 5 bottom surface of tooling pressing plate, and the balance weight 6 being arranged in pairs divides
The second bolt penetration hole corresponding with the first bolt penetration hole is not offered, is worn using the pre- stud mounted in cylinder cap across first bolt
Hole and the second bolt penetration hole fix the auxiliary device with two nut preloads again.
The bottom end of steel cylinder 4 is fixed on the top surface of tooling pressing plate 5, and the tube chamber of steel cylinder 4 is aligned with fuel injector perforation.Swivel nut 2 is logical
The top inner circumferential that its periphery is fixed on steel cylinder 4 is crossed, swivel nut 2 has the axial internal thread hole being adapted to tooling bolt.
The stud lower end of tooling bolt 1 is spirally connected with the axial internal thread hole of swivel nut 2, and is pierced by the tube chamber of steel cylinder 4.
The bottom surface of tooling sleeve 3 has the fuel injector oil inlet top surface locating slot of indent, and tooling sleeve 3 is consolidated by its top surface
It is scheduled on the stud lower end of tooling bolt 1, it is preferred that tooling sleeve 3 is weldingly fixed on the stud lower end of tooling bolt 1, fuel injector
Oil inlet top surface locating slot is the circular groove being adapted to the oil inlet top surface of fuel injector.
During detection, for fuel injector as required in cylinder head fuel injector hole, the oil inlet top surface of fuel injector passes through tooling pressing plate 5
Fuel injector perforation after, abut positioning with the fuel injector oil inlet top surface of tooling sleeve 3 positioning groove bottom, then with determining Torque wrench
The torque of tooling bolt is tightened by technological requirement, the protrusion height of fuel injector is finally measured with dial gauge.Fuel injector protrusion is high
The auxiliary device of degree detection only tightens the detection that a tooling bolt meets protrusion height of oil sprayer, is not required to intersect multiple make-up
Two nuts at left and right sides of the pressing plate of fixing fuel injector shoulder are avoided because moment unbalance causes fuel injector protrusion high on nut
It spends unqualified, production efficiency greatly improved, reduce labor intensity.
To sum up, the auxiliary device which detects only tightens a tooling bolt and meets fuel injector protrusion
The detection of height is not required to intersect two nuts at left and right sides of the pressing plate for repeatedly tightening fixing fuel injector shoulder, avoids because of nut
Upper moment unbalance causes protrusion height of oil sprayer unqualified, and production efficiency greatly improved, and reduces labor intensity.
