Description
Technical field
It the utility model is related to a kind of parallelism measuring apparatus, and in particular in survey aircraft production process between structure
The technical field of the depth of parallelism and its specific deviation.
Background technology
During aircraft manufacturing, often there is corresponding measurement of paralleism requirement to positions such as some structural frames, connectors,
But manufacture there is error, in order to accurately grasp and understand the scope of foozle, so as in follow-up assembling or component installation
During, determine whether parallelism error influences subsequently to assemble.
The content of the invention
The purpose of this utility model is to provide a kind of parallelism measuring apparatus, during aircraft manufacturing, checks part
Between the depth of parallelism whether meet the requirements, accurately grasp part manufacture or confined state.
The utility model to achieve these goals, adopts the following technical scheme that：
A kind of parallelism measuring apparatus, includes support arm, measuring appliance, lever arm；
The fixing end of support arm is bonded with one end of tested part, lever arm is bonded with the other end of tested part；
The fixture block of measuring appliance lower end is put into the card slot of support arm.
Further, there is the oblique angle of two 45° angles in the card slot of lever arm lower end respectively, have circle respectively on the top at oblique angle
Angle.
Further, it is provided with graduation mark on the measuring appliance.
When needing to measure the depth of parallelism between two parts, support arm right side is close to one of tested part
Measuring surface, lever arm guide card is placed in the card slot of support arm, then moves lever arm to other one along card slot direction
The measuring surface of a tested parts, and be bonded with measured surface.Support arm and activity are put into measuring appliance band Measurement scales one end
In gap between arm, the scale value on measuring appliance is read, then scale value is the depth of parallelism that need to be measured.
The beneficial effects of the utility model：
This measuring device is highly practical, and cost is low, highly reliable, easy to operate.Can be in production scene fast and accurately
The depth of parallelism of tested parts is measured, certain production efficiency can be improved.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the lever arm sectional view of the utility model；
Fig. 3 is the front view of the measuring appliance of the utility model；
Fig. 4 is the isometric views of the measuring appliance of the utility model.
Embodiment
The utility model is described in detail below in conjunction with the accompanying drawings:
A kind of parallelism measuring apparatus such as Fig. 1, includes support arm 1, measuring appliance 2, lever arm 3；
The fixing end of support arm 1 is bonded with one end of tested part 4, lever arm 3 and the other end of tested part 4 are pasted
Close；The fixture block 5 of 2 lower end of measuring appliance is put into the card slot of support arm 1.
There is the oblique angle of two 45° angles in 3 lower end card slot of lever arm respectively, be rounded down respectively on the top at oblique angle.
Graduation mark 6 is provided with the measuring appliance 2.
Measuring appliance 2 is promoted to 3 direction of lever arm, until in the gap completely into lever arm 3；Then measuring appliance 2 is read
Measured value above.
Fig. 2 is the sectional view of lever arm 3, has the oblique angle of two 45° angles in the card slot of lower end respectively, distinguishes on the top at oblique angle
Rounded corner.
Fig. 3 is the front view of measuring appliance 2, and there are a fixture block 5, fixture block 5 and the one of measuring appliance 2 in lower end, may be inserted into support arm 1
Card slot in, rise be oriented to and fixation.
Fig. 4 be measuring appliance 2 isometric views, the 6 Direct Mark angle value of graduation mark of upper end, such as in units of 10 ', groove
It is the axial offset by 3 lower end oblique angle top of lever arm on measuring appliance 2, is counted with reference to trigonometric function calculation formula
Calculate, and obtained after being verified by actual production, it is not what is be evenly distributed, graduation mark 6 is only to illustrate in Fig. 4.
