The utility model discloses a kind of drag-line EPB sealability detection auxiliary devices, including the sealing shroud with seal chamber, the snap-gauge fixed with sealing shroud, drag-line head, which is packed into the rubber parts in seal chamber and on drag-line and seals cavity wall sealing, to be cooperated, the snap-gauge is equipped with U-shaped lower bayonet and upper latch notch, the upper latch notch and drag-line are clamped, the external wall of upper portion of the sealing shroud is equipped with card slot, and the lower bayonet and card slot are clamped.The utility model is when being sealed property of drag-line EPB detects, for the natively drag-line head of blow-by on sealed guy cable two-end structure, realize that drag-line EPB can pass through the accurate testing product of leakage instrument, the leakproofness of product is set accurately to detect using the leakproofness auxiliary detection device, labor intensity is little simultaneously, easy to loading and unloading.
Description
Technical field
The utility model relates to auto parts and components technologies, and in particular to drag-line EPB sealing propertytest technology.
Background technique
The sealing requirements of automobile guy cable formula EPB (electronic brake system) upper cover and lower case are IP6K7, but EPB
The bracing wire of inhaul cable assembly be all process, bracing wire and Cable head to guarantee that connection reliably generallys use the form of hot-cast,
The high temperature of the protection unbearable hot-cast of sebific duct outside bracing wire, therefore cannot be guaranteed sealing substantially herein, and bracing wire is process, is led to
It crosses using all less feasible of sealant etc, at present when using the detection of being sealed property of leakage instrument, usually permits leakage
Perhaps value amplification, to carry out the sealing propertytest of upper cover and lower case, the leakage value for being easy to appear upper cover and lower case compares value of magnification
Small unqualified part erroneous judgement.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of drag-line EPB sealability detection auxiliary device,
Upper cover and lower case sealing performance is set to access accurate detection.
In order to solve the above technical problems, the utility model adopts the following technical solution: a kind of drag-line EPB sealing propertytest
Auxiliary device, including the sealing shroud with seal chamber, the snap-gauge fixed with sealing shroud, drag-line head is packed into seal chamber and drag-line
On rubber parts and sealing cavity wall sealing cooperate.
Preferably, the snap-gauge is equipped with U-shaped lower bayonet and upper latch notch, and the upper latch notch and drag-line are clamped, the sealing
The external wall of upper portion of set is equipped with card slot, and the lower bayonet and card slot are clamped.
Preferably, connection bolt is connected between the oral area two sides of the lower bayonet.
Preferably, the inlet design of the sealing shroud has a chamfering no more than 30 degree, and the surface roughness of chamfering, close
The surface roughness of big envelope and rubber parts cooperation section is all larger than Ra0.8.
Preferably, the surface roughness requirements that the snap-gauge and drag-line and sealing shroud cooperate are in Ra1.6 or more.
Preferably, the snap-gauge selects aluminium alloy to be made with sealing shroud, while surface hard anode oxidation.
The utility model is used on sealed guy cable two-end structure natively not when being sealed property of drag-line EPB detects
The drag-line head of sealing realizes that drag-line EPB can assist detection dress using the leakproofness by the accurate testing product of leakage instrument
Setting enables the leakproofness of product accurately to detect, while labor intensity is little, easy to loading and unloading.
Detailed description of the invention
The utility model is further described with reference to the accompanying drawings and detailed description:
Fig. 1 is the structural schematic diagram of the utility model in a state of use；
Fig. 2 is snap-gauge and connect structural schematic diagram after bolt assembling；
Fig. 3 is the main view of snap-gauge；
Fig. 4 is the top view of snap-gauge；
Fig. 5 is the structural schematic diagram of sealing shroud.
Specific embodiment
The technical solution of the utility model embodiment is explained below with reference to the attached drawing of the utility model embodiment and
Illustrate, but following embodiments are only the preferred embodiment of the utility model, and not all.Based on the implementation example in the implementation mode,
Those skilled in the art's obtained other embodiments without making creative work, belong to the utility model
Protection scope.
As shown in Figure 1, a kind of drag-line EPB sealability detection auxiliary device, including with seal chamber 11 sealing shroud 1,
The fixed snap-gauge 2 with sealing shroud 1, the head of drag-line 4 are packed into rubber parts and sealing cavity wall sealing in seal chamber and on drag-line
Cooperation, is first sealed the local location that drag-line can not inherently seal by sealing shroud 1, allow it is total it is integral can be close
Envelope, then pass through leakage instrument being sealed property performance detection.
Wherein, as shown in Figures 2 to 5, the snap-gauge 2 is equipped with U-shaped lower bayonet 22 and upper latch notch 21, the upper latch notch 21
It is clamped with drag-line 4, the external wall of upper portion of the sealing shroud 1 is equipped with card slot 11, and the lower bayonet 22 is clamped with card slot 11.The lower card
Connection bolt 3 is connected between the oral area two sides of mouth 22.Snap-gauge 2 is used to fixing seal set 1, and sealing shroud 1 is made to be mounted in the position of product
Set fixation, can guarantee sealing during sealing propertytest, and loading/unloading products relatively aspect again, when not in use snap-gauge with it is close
Big envelope will not be disengaged mutually, by connection bolt limit in favor of storage.
The present embodiment is preferred, and the inlet design of the sealing shroud 1 has the chamfering no more than 30 degree, and the surface of chamfering
The surface roughness of roughness, sealing shroud and rubber parts cooperation section is all larger than Ra0.8, and it is close to guarantee that the rubber parts on drag-line head is packed into
It is not injured when big envelope and laborsaving when loading.The surface roughness requirements that the snap-gauge 2 cooperates with drag-line 4 and sealing shroud 1 exist
Ra1.6 or more facilitates the handling of snap-gauge and drag-line.
The snap-gauge 2 selects aluminium alloy to be made with sealing shroud 1, while surface hard anode oxidation, and thickness is greater than 0.01mm,
In the case where device is light, the service life is guaranteed.Snap-gauge 2 is in Rouno Cormer Pregrinding Wheel mistake with respect to the back side corner of upper latch notch 21 and lower bayonet 22
It crosses, makes power when snap-gauge and sealing shroud and drag-line cooperate.
In addition, snap-gauge 2 is caught in the position of drag-line, it to be more than the center of drag-line, but the distance controlling for being more than is on the left side 2mm
The right side, position is reliable when blocking, and when pickup is quick.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, being familiar with the those skilled in the art should be understood that the utility model includes but is not limited to attached drawing and specific embodiment party above
Content described in formula.The modification of any function and structure principle without departing from the utility model is intended to be included in claims
Range in.
