Embodiment
Explanation and embodiment further illustrate to the utility model below in conjunction with the accompanying drawings.
As shown in Figures 1 to 8, the utility model includes bottom plate 00, the copying support being welded on bottom plate 00 and passed through
Bolt is fixed on bottom plate 00 alignment pin 07 for being used for being oriented to profiling fixture installation, the copying support bag from top to bottom
6 the first copying supports 01 and 4 the second copying supports are included, and fully the surface of the cylinder cap 08 is used using D/A system
D/A system carries out interference analysis, determines 4 kind of second copying support；Second copying support includes first the second profiling branch
02, second the second copying support 03 of frame, the 3rd the second copying support 04, the 4th the second copying support 05, described first
Individual second copying support, 02, second the second copying support 03, the 3rd the second copying support 04, the 4th the second copying support
05 is respectively welded on four angles of the bottom plate 00, and 6 uniform weldings of the first copying support 01 are on bottom plate 00, and two
The mounting hole 09 for being used for installing valve spring, spring base and valve collet, the installation are provided among amount copying support side by side
Hole is slightly different according to the difference of engine model.
It is parallel to each other and the rectangular panel and two of width not etc. as shown in figure 4, first copying support 01 includes two
Individual size identical isosceles trapezoid panel, two isosceles trapezoid panel parallel short sides connect, and have between two isosceles trapezoid panels
Angle, the parallel long side of the two isosceles trapezoids panel connects with the long side of rectangular panel respectively, and one of isosceles trapezoid
Panel and the big rectangular panel vertical connection, the length of the rectangular panel are more than the isosceles trapezoid panel parallel long side
It is long.
As shown in figure 5, first second copying support 02 is compared with first copying support 01, it is described to connect two
The panel for disposing rectangular panel is right-angled trapezium panel.
As shown in fig. 6, the difference of second second copying support 03 and first second copying support 02 exists
In second second copying support 03 is the DTS of first the second copying support 02.
As shown in Fig. 4 to Fig. 8, the copying support is welded by some panels of different shapes, or by one
The punching of block panel forms, the corner angle of the copying support and bottom plate 00 be all polished it is smooth, to prevent installing the profiling work
When being attached on cylinder cap 08, profiling fixture scratches cylinder cap 08.The material of the copying support and bottom plate 00 is that 45# steel processes melanism
Form, the very thin thickness of the bottom plate 00 and copying support, profiling fixture is also ensure that while profiling fixture hardness is ensured
Quality, make it not cause to install, dismantle inconvenience because profiling fixture is too heavy, and because of profiling fixture quality itself
It is too heavy and cause to deform upon so that profiling fixture does not agree with the hole on cylinder cap 08, and has valve collet to fall from gap
Fall in cylinder cap.And metal profiling fixture also ensure that profiling fixture when the cylinder cap with aluminum is rubbed, collided with
Do not produce material chips, it is ensured that do not have chip and fall into cylinder cap, cylinder cap is polluted.
The alignment pin 07 is fixed among bottom plate 00 from top to bottom by bolt, is seen and can directly be observed from bottom plate 00
To the bolt head of bolt, to ensure that operative employee can at every moment observe bolt during using the profiling fixture
State, release and fallen into inside cylinder cap to prevent bolt, damage cylinder cap.And the alignment pin 07 is no less than 2, and positioned for extended type
Pin 07, the material of the alignment pin 07 is nylon, and nylon is light and solid, is particularly suitable for being installed on thin bottom plate 00.
U-shaped handle 06 is installed on the bottom plate 00, and wear-resisting antiskid protection is carried out at handle 06, is grasped for convenient
Workmanship's installation, dismounting profiling fixture.The handle 06 and 45# steel are cast, then carry out Darkening process.
As shown in Figure 1 and Figure 2, first copying support 01 is covered on 010 hole on cylinder cap 08, described first
Second copying support 02 is covered on 020 hole on the cylinder cap 08, and second second copying support 03 is covered in institute
To state on 030 hole on cylinder cap 08, the 3rd second copying support 04 is covered on 040 hole on the cylinder cap 08,
4th second copying support 05 is covered on 050 hole on the cylinder cap 08；The alignment pin 06 inserts the cylinder
In spark plug mounting hole 070 on lid 08, for the profiling fixture of installation to be oriented to and positioned.Copying support shelters from cylinder
The hole of cap upper surface, while reserve the mounting hole 09 for installing valve spring, spring base and valve collet；Preventing
While valve collet is dropped in cylinder cap, the operation to station does not impact again.
The profiling fixture does not fall into the event of cylinder cap in the experimentation of 1 year in generation lock first.The maintenance of reduction
Cheng Ben $570.00, the engine scrap cost of reduction is $14570.00.Substantial amounts of man power and material is saved.It is and described imitative
, stronger flexibility be present in the various engines types such as shape frock compatibility B150/B12T/B15T.Positioned using alignment pin 06,
Reliability is high, easy to maintenance, simple to operate, has both avoided profiling fixture and has been rocked on cylinder cap, while avoids profiling fixture and knock
Cylinder cap is touched, scratches cylinder cap.The profiling fixture is light succinct, simple to operate, and the behaviour of station is not installed to the valve collet
Workmanship causes extra burden.The risk that valve collet is fallen into cylinder cap is fundamentally avoided, has eradicated market after sale to this
The complaint of class event, greatly improve the assembling quality of automobile industry.
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that specific implementation of the present utility model is confined to these explanations.For the ordinary skill of the utility model art
For personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should all be regarded
To belong to the scope of protection of the utility model.
