Description
Technical field
The present invention is a kind of device of checking position of mounting hole, is specifically related to a kind of testing fixture that is used for bolt mounting holes is distributed in the correct position on two the curved surfaces of part by bolts assemblies
Background technology
In the assembling of the parts of automobile, the face that is fitted to each other that runs into two Assembly parts through regular meeting is a curved surface, and the form that adopts bolt to be linked and packed simultaneously, for example the assembling of the exhaust manifold of motor car engine and heat shield just belongs to this form.In this situation, bolt mounting holes is to be distributed on the curved surface of two parts, in brill, punch process, there is certain degree of difficulty in control to the bolt mounting holes position of related features on the technology, dislocation appears and control the bad corresponding bolt mounting holes of two parts that just causes easily, thereby influence assembling, this is unfavorable for producing in enormous quantities.Therefore for improving efficiency of assembling, just the bolt mounting holes position to part is checked necessary before assembling.But, in the production practices, lack a kind of like this checking tool.
Summary of the invention
Technical matters to be solved by this invention provides a kind of device for detecting positions of bolt mounting holes, the correct position that bolt mounting holes is distributed on two the curved surfaces of part by bolts assemblies is checked, produced mutual dislocation with the bolt mounting holes of avoiding two parts in assembling process.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
A kind of device for detecting positions of bolt mounting holes is used for bolt mounting holes is distributed in the inspection of the correct position on two the curved surfaces of part by bolts assemblies; It is characterized in that: it comprises a curved slab, and the space curved surface of the bolt mounting holes distributing position on described curved slab and the described part is consistent; On the concave surface of described curved slab, with on the described part wherein corresponding place, at least one bolt mounting holes position the stiff end awl is set, the corresponding one by one via hole that is provided with in place corresponding on the concave surface with remaining bolt mounting holes position on the described part, also configuration is bored with the movable end that described via hole is used one by one in addition, bore greater than stiff end in the aperture of described via hole, it equals the tolerance that allows between the bolt mounting holes of two parts greater than amount, the size and the bolt sizableness that is connected described two parts of described stiff end awl and movable end awl, the movable end awl can directly just adopt bolt.
The present invention is inserted in the corresponding bolt mounting holes of part by the awl of the stiff end on the curved slab, locate whole device, at this moment, each via hole on the curved slab just should be the tram of their bolt mounting holes corresponding to the position on the part, by the movable end awl is inserted each via hole, and allow it in margin tolerance, to move, check whether the movable end awl can all enter in the bolt mounting holes of part, and then whether the layout of the bolt mounting holes on the detection part meets the requirements.
The present invention can be easily detects the position of the bolt mounting holes of the part of curved-surface structure, have reasonable in design, technology simple, make advantages such as easy, easy to use.

Embodiment
Following the present invention is an example with enmgine exhaust and two parts that assemble mutually of heat shield, and the concrete structure of this testing fixture is described.
The cast iron exhaust manifold of engine is because of the influence of the waste gas of being discharged, and often the temperature height causes scald to the people easily, has therefore generally installed heat shield additional in its appearance, and both are by the bolt connection.Therefore the bolt mounting holes of exhaust manifold and heat shield has corresponding relation.Because the profile of exhaust manifold is a curved surface, therefore each mounting hole position is generally the space curved surface structure, there is certain degree of difficulty in the control of the bolt mounting holes position of related features of exhaust manifold and heat shield in brill, punch process, control bad just dislocation easily, thereby influence assembling, this is unfavorable for the production in enormous quantities of engine.
The testing fixture that the present invention proposes just can realize the position of their bolt mounting holes is checked that as shown in Figure 1 and Figure 2, testing fixture is made of curved slab 4, movable end awl 1, stiff end awl 3 and handle 2.Curved slab 4 has the consistent cambered surface of space curved surface structure with the bolt mounting holes position of exhaust manifold and heat shield, and stiff end awl 3 is positioned on the concave surface of curved slab 4, and corresponding with one of them bolt mounting holes position on exhaust manifold and the heat shield.And in the place corresponding with remaining bolt mounting holes position on exhaust manifold and the heat shield the corresponding one by one via hole that is provided with, referring to Fig. 3.Also has the movable end awl 1 that is used one by one with described via hole in addition.Bore greater than stiff end in the aperture of via hole, considers tolerance, and it equals the tolerance that allows between the bolt mounting holes of exhaust manifold and heat shield greater than amount, and promptly the aperture of via hole is the maximal value that movable end awl 1 can moving range.Stiff end awl 3 and movable end are bored the number that 1 quantity sum equals bolt mounting holes.The size that stiff end awl and movable end are bored is with to be connected exhaust manifold suitable with the heat shield bolt.Also can directly just adopt bolt to do the movable end awl.
For easy to use, a fixedly connected handle 2 on the convex surface of curved slab 4, when detecting, personnel can pick and place this device easily like this.
This Device Testing method is: when detecting exhaust manifold, hold handle 2, the concave surface of this device is attached on the exhaust manifold, simultaneously stiff end awl 3 is inserted the bolt mounting holes of correspondence position on the exhaust manifolds, after treating the device location, again in the via hole that movable end awl 1 is inserted on the curved slab 4.If movable end awl 1 is by regulating in the bolt mounting holes that can insert fully simultaneously on the exhaust manifold, then the bolt mounting holes position on this exhaust manifold meets the requirements.If by adjusting the position of movable end awl 1 in via hole, in movable end awl 1 bolt mounting holes that still can not enter fully on the exhaust manifold, then the bolt hole position layout on this exhaust manifold is undesirable.Whether the hole arrangement on the heat shield meets the requirements, and can make the detection that uses the same method.
By this Device Testing, if when movable end awl 1 can both enter bolt mounting holes on the exhaust manifold and the hole on the heat shield fully, then exhaust manifold can be connected by bolt with heat shield.If movable end awl 1 can only enter one in bolt mounting holes on the exhaust manifold and the hole on the heat shield fully, perhaps two all can not enter the time, then exhaust manifold can not be connected by bolt with heat shield.
