Abstract
The utility model relates to an air tightness detection device for a fuel pipe union. The air tightness detection device for a fuel pipe union comprises a box body filled with water, and is characterized in that a work flat is arranged in the box body; the work flat is connected with the box body through a lifting cylinder so as to make the work flat do lifting motion in the box body; a positioning slot for mounting a positioning fuel pipe union is arranged on the work flat so as to make the fuel pipe union do not play; the work flat is also provided with end caps for blocking up the orifice of the fuel pipe union; and one of the end cap is plugged with a high-pressure air tube for ventilating high pressure air. The air tightness detection device for a fuel pipe union can quickly detect the tightness of each welding parts of the fuel pipe union, and can guarantee that only the fuel pipe union with good air tightness can be used for producing cars.
Description
Technical field
The utility model relates to a kind of tubing sub air-tightness detection device.
Background technology
Tubing sub one is welded to each other by at least two parts and forms, so just must adhere to the sealing of welding position, secure welding position good airproof performance only, the impermeability of whole tubing sub is protected, so just can be installed on the automobile and use, ensure the safety of automobile, eliminate bad potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide a kind of tubing sub air-tightness detection device, and this device can detect the sealing of each weld of tubing sub fast, guarantees that the good tubing sub of impermeability just can use in the production automobile.
The technical solution of the utility model is: a kind of tubing sub air-tightness detection device, comprise the casing that water is housed, it is characterized in that: be provided with a working plate in the described casing, described working plate is connected with casing so that working plate moves up and down in casing through lift cylinder; Be provided with the locating groove of installation location tubing sub on the described working plate so that oil pipe
Play does not occur in joint, also is provided with on the described working plate be used to the plug of blocking the tubing sub mouth of pipe, and wherein a plug is plugged with the high-pressure air pipe for logical high pressure gas.
Further, thus described plug one end is connected with and drives cylinder and be used for driving the mouth of pipe that tubing sub is blocked in the plug motion.
The utility model has the advantage of: the topology layout advantages of simple, simple to operate, principle is simple and easy, can detect fast the sealing of each weld of tubing sub, guarantee that the good tubing sub of impermeability just can use in the production automobile, thereby ensure the stable of the interior oil circuit of automobile.

Embodiment
For above-mentioned feature and advantage of the present utility model can be become apparent, embodiment cited below particularly, and cooperation accompanying drawing be described in detail below, but the utility model are not limited to this.
With reference to legend, a kind of tubing sub air-tightness detection device, comprise the casing 1 that water is housed, it is characterized in that: be provided with a working plate 2 in the described casing, described working plate is connected with casing so that working plate moves up and down in casing through lift cylinder 3; Be provided with the locating groove 5 of installation location tubing sub 4 on the described working plate so that play does not occur tubing sub, also be provided with on the described working plate be used to the plug 6 of blocking the tubing sub mouth of pipe, wherein a plug is plugged with the high-pressure air pipe 7 for logical high pressure gas.
Thereby described plug one end is connected with and drives cylinder 8 is blocked tubing sub for the motion of drive plug the mouth of pipe.
Among the utility model embodiment one: be provided with a pair of locating groove for the location tubing sub at working plate, see Fig. 2 for details.
Among the utility model embodiment two, be provided with a locating groove that is used for the location tubing sub at working plate, see Fig. 3 for details.
Testing process of the present utility model is: tubing sub is connected in the locating groove, guarantee that play (be not specially in the utility model and at surface level play occur) does not occur tubing sub, then starting the driving cylinder makes three plugs block respectively three mouths of pipe of tubing sub, drive lift cylinder, working plate is deep in the water, being specially whole tubing sub is immersed in the water, in tubing sub, pass into high pressure gas, whether the welding position of observing tubing sub has Bubble formation, the impermeability that were it not for this tubing sub of explanation is good, does not meet the requirement of production if general Bubble formation then illustrates this part tubing sub; If produce bubble at the plug place, illustrate that then plug does not block each mouth of pipe of tubing sub, need again the tubing sub mouth of pipe to be blocked work.
The above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
