, with instrument be connected port using pipeline by the port that instrument connects, and is then tested.
The content of detection is needed during engine production generally has engine cylinder block water channel leak-testing, oil duct to leak
Test, engine cylinder cap water channel leak-testing, oil duct leak-testing, the test of cylinder cap assembly air valve tightness, hair
Motivation assembly oil duct leak-testing and air flue leak-testing.
By cylinder cap assembly air valve tightness test as a example by, current legacy equipment by frame 11, detent mechanism 12,
Roller Conveyors structure 13, sealing clamp 14, valve beater mechanism 15 are constituted.
Utility model content
The purpose of this utility model is to make up the deficiencies in the prior art, there is provided one kind can overcome sealing surface with it is close
The sealing pressure head of front cover parallelism error, can eliminate the cumulative errors caused by processing, assembling, make equipment to different workpieces
The characteristics of sealing effectiveness tends to identical.
In order to reach the purpose of this utility model, technical scheme is as follows：
It is a kind of to overcome sealing surface and the sealing pressure head by sealing surface parallelism error, including sealed base and sealing plate,
Characterized in that, being connected by floating structure between the sealing plate and sealed base, the floating structure includes band shoulder spiral shell
Bolt), spheric washer, taper faced washer, compression spring,
Sealed base is provided with step mounting hole, and taper faced washer is fixed in the step mounting hole, and spheric washer is close to
It is arranged between taper faced washer and sealing plate in taper faced washer；The inner of shouldered tap bolt is placed in sealed base, outside shouldered tap bolt
It is connected with sealing plate after holding the step mounting hole through sealed base, spheric washer and taper faced washer；Compression spring is enclosed within band shoulder
Bolt outside, one end of compression spring is withstood on the inner face of sealed base, the inner of the compression spring other end and shouldered tap bolt
Portion connects.
Preferably, it is provided with spring shim between the end of the compression spring and the inner face of sealed base, compression spring,
Spring shim collective effect makes shouldered tap bolt tense sealing plate, sealing plate is close on spheric washer.
Preferably, also including straight pin, one end of straight pin is fixed on sealed base, the hole on the other end and sealing plate
Coordinate.
Preferably, there is gap between shouldered tap bolt and sealed base, sealing plate is swung in diagram X-direction.
The utility model has the advantage that：
The part processing cumulative errors between workpiece locating mechanism and sealing mechanism can be eliminated, can be eliminated between different workpieces
Scale error.The sealing state of different workpieces is set to tend to identical, so that equipment test data is more stable.
Brief description of the drawings
Fig. 1 is the structural representation of test equipment.
Fig. 2 is that this practicality can overcome sealing surface and the structural representation by the sealing pressure head of sealing surface parallelism error；
Fig. 3 is the overlooking the structure diagram of Fig. 2.
Specific embodiment
The utility model is further described with reference to embodiment, but protection domain of the present utility model not only office
It is limited to embodiment.
It is a kind of to overcome sealing surface and the sealing pressure head by sealing surface parallelism error including close with reference to shown in Fig. 2-Fig. 3
Back cover seat 1 and sealing plate 2, are connected between the sealing plate 2 and sealed base 1 by floating structure, and the floating structure includes
Shouldered tap bolt 4, spheric washer 5, taper faced washer 6, compression spring 9.
Sealed base 1 is provided with step mounting hole, and taper faced washer 6 is fixed in the step mounting hole.Spheric washer 5 is tight
It is affixed on taper faced washer 6 and between taper faced washer 5 and sealing plate 2.The inner of shouldered tap bolt 4 is placed in sealed base 1, band
The outer end of rotator bolt 4 with sealing plate 2 through being connected after the step mounting hole of sealed base, spheric washer 5 and taper faced washer 6.
Compression spring 9 is enclosed within the outside of shouldered tap bolt 4, and the right-hand member of compression spring 9 withstands on the inner face of sealed base 1, presses
The left end of contracting spring 9 is connected with the inner end of shouldered tap bolt 4.Set between the end of compression spring 9 and the inner face of sealed base 1
There is a spring shim 7, compression spring 9 produces elastic force to the left, apply the active force that shouldered tap bolt 4 is moved to the left, compression spring 9,
The collective effect of spring shim 7 makes shouldered tap bolt 4 tense sealing plate 2, sealing plate 2 is close on spheric washer 6.
