Description
Technical field
The utility model relates to a kind of fixed anti-welding leakage devices of flange, belong to oil pipe welding technology field.
Background technique
Flange is seen everywhere in we live, and the both ends in oil pipe industry in EGR pipe usually require welded flange, is passed
All it is directly to be welded when the welding EGR pipe of system, cannot be guaranteed when cannot fix EGR pipe and ring flange well, and weld
The case where edge of flanged pipe and ring flange is in close contact, and weldering is be easy to cause to leak, increases the disqualification rate of product, and reduce
Working efficiency.
Utility model content
The utility model in view of the above-mentioned deficiencies in the prior art, provides a kind of fixed anti-welding leakage device of flange.
The technical solution that the utility model solves above-mentioned technical problem is as follows:
A kind of fixed anti-welding leakage device of flange, including device noumenon, described device ontology includes oil cylinder, rise axis and the pawl that rises,
The axis that rises is fixed on the top of oil cylinder, and the pawl that rises is connected to the top for the axis that rises, and the outside of the axis that rises is additionally provided with connector sleeve,
The connection set upper side is connected with connecting plate.
Further, the connecting plate and connector sleeve are hollow structure, are socketed in the outside of rise axis and the pawl that rises.
Further, it is additionally provided with axis at the top of the connecting plate, is evenly distributed on the two sides on pawl top of rising.
Further, ring flange is placed on the connecting plate, the opening on ring flange side is connected on axis.
Further, it is provided with circular hole at the center of the ring flange, is placed with flanged pipe in circular hole.
Further, the flanged pipe is EGR pipe, is located inside flanged pipe at the top of the pawl that rises.
Further, the idler wheel for controlling the pawl opening degree size that rises is additionally provided on the hollow two sidewalls of the connecting plate.
Compared with prior art, the utility model has the beneficial effects that ring flange and flanged pipe are all placed on connecting plate
On, fixed position, axis is connected on ring flange inner hole, prevents flange disc spins, play orientation, and the pawl that rises is in flanged pipe
Interior, multijaw multiple spot mounting flange pipe makes the inner wall of flanged pipe be in close contact ring flange, effectively prevent weldering leakage phenomenon, improves welding
Efficiency reduces the defect rate of product, save the cost.

Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
A kind of fixed anti-welding leakage device of flange, including device noumenon, described device ontology includes oil cylinder 6, rise axis 4 and the pawl that rises
3, the axis 4 that rises is fixed on the top of oil cylinder 6, and the pawl 3 that rises is connected to the top for the axis 4 that rises, and the outside for rising by axis 4 is additionally provided with
Connector sleeve 5,5 upper end of connector sleeve are connected with connecting plate 2.
The connecting plate 2 and connector sleeve 5 are hollow structure, are socketed in the outside of rise axis 4 and the pawl 3 that rises.
The top of the connecting plate 2 is additionally provided with axis 8, is evenly distributed on the two sides on 3 top of pawl of rising.
Ring flange 1 is placed on the connecting plate 2, the opening on 1 side of ring flange is connected on axis 8.
It is provided with circular hole at the center of the ring flange 1, flanged pipe 7 is placed in circular hole.
The flanged pipe 7 is EGR pipe, and the top for rising by pawl 3 is located inside flanged pipe 7.
The idler wheel for controlling the 3 opening degree size of pawl that rises is additionally provided on the hollow two sidewalls of the connecting plate 2.
Embodiment
In use, ring flange 1 is placed on connecting plate 2, with 8 fixed-direction of axis, flanged pipe 7 is placed on ring flange
Inside 1, oil cylinder 6 is moved upwards, so that the opening of pawl 3 that rises be pushed to fix flanged pipe 7, is welded.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
