Abstract
The utility model provides a flange seal blanking element for an engine crankshaft. The flange seal blanking element for the engine crankshaft comprises a front-end seal ring, a front-end seal plate, a central flexible seal plate, a rear-part seal plate and a plurality of spiral locking pins, wherein all the holes in a flange of the crankshaft are enveloped by the front-end seal ring, due to extrusion action in locking of the spiral locking pins, the holes are reduced after the central flexible seal plate is deformed, so as to closely clasp the spiral locking pins, in addition, steps of the spiral locking pins and the central flexible seal plate are in plane seal to jointly form a seal shield, thereby being capable of resisting high aeration pressure without leakage.
Description
Technical field
The utility model relates to the crankcase seals property testing, relates in particular to engine crankshaft flange seal blocking piece.
Background technique
In the engine design of current engine manufacturing, nearly all engine crankshaft all is with the crankshaft flange of a plurality of screws (being generally 6 ~ 18) and (Shanghai Volkswagen's motor is 8) of flywheel binding by one.Simultaneously, nearly all motor all utilizes this end face of flange deallocation to close crank shaft oil seal simultaneously, thereby guarantees the sealing of crankcase, as shown in Figure 1.
The advantage of this structure is simple in structure, processing facility, but the test before it but dispatches from the factory to motor has brought some inconvenience.Reason is, before motor dispatches from the factory, must be through the crankcase seals property testing, but since the screw break-through on the crankshaft flange crankshaft flange, therefore can cause gas leakage, affect test result.Therefore must be first with all the screw sealings on the crankshaft flange before sealing test.
In the prior art, the main flow scheme of sealing crankshaft flange tapped hole has following two kinds.
The first scheme is to utilize bolt to be screwed into first all tapped holes, and all tapped holes are blocked.
Yet the shortcoming of the first scheme is: what tapped holes are arranged on the crankshaft flange, will be screwed into what bolts before the sealing test, so workload is very large, affects very much productive temp, labor strength is also very high.Obviously and nowadays more and more higher productivity of each engine works is inadaptable for this.
First scheme is to use external equipment to push away a plug and come, and disposablely pushes down all tapped holes.
Yet first scheme has following shortcoming.At first, need to build the special-purpose equipment of a cover, fund input is large.Secondly, flexibility is not enough, can not adapt to the demand of remodeling of various engines mixed production.Again, there is risk in this scheme in operation, and the deviations motor of will wounding is slightly arranged.
Therefore, need a kind of defective that can overcome above-mentioned prior art badly and the device of tapped hole that can the canned motor crankshaft flange.
The model utility content
In order to overcome the defective of prior art, the utility model provides a kind of novel engine crankshaft flange seal blocking piece.Described engine crankshaft flange seal blocking piece comprises:
The forward end seal circle;
Forward end seal plate, described forward end seal circle are attached on the described forward end seal plate;
Central authorities' flexible sealing plate, adjacent with described forward end seal plate;
The rear seal plate, adjacent with described central flexible sealing plate; And
A plurality of spiral spring bolts run through described rear seal plate and central flexible sealing plate.
In one embodiment, described a plurality of spiral spring bolt is three spiral spring bolts.
In one embodiment, described forward end seal circle with the whole envelopes of all screws on the crankshaft flange wherein.
In one embodiment, has plane sealing between the step of described spiral spring bolt and the described central flexible sealing plate.
In one embodiment, described engine crankshaft flange seal blocking piece also comprises a plurality of standard nuts and locating stud.
The beneficial effects of the utility model are as follows:
1. no matter on the crankshaft flange how many holes are arranged, only need to twist three just passable, and three spring bolts are disposable alignings, and are very convenient quick.
2. creatively utilized the principle of " hole behind the flexible material pressurized on the material diminishes ".
3. the spiral spring bolt utilizes the flexible material location and with plane sealing, therefore can adapt to the larger Tolerance of Degree of position of crankshaft flange screw.
4. the footprint pressure of all sealing surfaces is very high, therefore can resist very high test inflation pressure.
Description of drawings
Fig. 1 illustrates the engine crankshaft flange with a plurality of screws;
Fig. 2 illustrates a kind of sealing blocking piece for the engine crankshaft flange according to an embodiment of the present utility model; And
Fig. 3 illustrates the use scenes according to an embodiment's of the present utility model sealing blocking piece.
Embodiment
Fig. 2 illustrates a kind of sealing blocking piece for the engine crankshaft flange according to an embodiment of the present utility model.
The sealing blocking piece that should be used for the engine crankshaft flange includes, but not limited to five critical pieces.These five parts are respectively forward end seal circle 1, forward end seal plate 2, central flexible sealing plate 3, rear seal plate 4, spiral spring bolt 5.Simultaneously, sealing blocking piece of the present utility model also comprises some standard nuts and locating stud.
Fig. 3 illustrates the use scenes according to an embodiment's of the present utility model sealing blocking piece.When using the sealing blocking piece, only need the sealing blocking piece is aimed at crankshaft flange, this moment, three pieces of spiral spring bolts 5 will be aimed at three screws on the crankshaft flange, next only need tighten three pieces of spiral spring bolts 5, will seal screws all on the crankshaft flange.Its principle is: forward end seal circle 1 with the whole envelopes of all screws on the crankshaft flange wherein, and the squeezing action during owing to 5 locking of spiral spring bolt, central authorities' flexible sealing plate 3 distortion metapores dwindle, tightly embrace spiral spring bolt 5, add the step of spiral spring bolt 5 and the plane sealing between the central flexible sealing plate 3, jointly formed sealing barrier one, can resist very high inflation pressure and do not leak.
This model utility has following characteristics:
1. no matter on the crankshaft flange how many holes are arranged, only need to twist three just passable, and three spring bolts are disposable alignings, and are very convenient quick.
2. creatively utilized the principle of " hole behind the flexible material pressurized on the material diminishes ".
3. the spiral spring bolt utilizes the flexible material location and with plane sealing, therefore can adapt to the larger Tolerance of Degree of position of crankshaft flange screw.
4. the footprint pressure of all sealing surfaces is very high, therefore can resist very high test inflation pressure.
Actual verification has been passed through in this invention, is used in the assembly shop sealing test station of haircuting, and effect is ideal.
Although description of the present utility model combines specific embodiment, but it should be understood by one skilled in the art that the utility model is not limited to embodiment described here, and can carry out various modifications and variations and do not deviate from spirit and scope of the present utility model.
