Description

On-line detection and inspection fixture for automobile exhaust system

technical field

The utility model relates to an inspection jig for the automobile field, in particular to an on-line inspection inspection jig for an automobile exhaust system. the

Background technique

my country's auto industry is in a state of rapid development, and the quality of auto parts and production efficiency have become the key factors affecting the development of the auto industry. At present, the inspection of automobile exhaust system generally uses three-coordinate measuring instrument to measure whether the exhaust system, the installation hole of the body and the suspension axis meet the requirements of the drawing to determine whether the product is qualified; or use a scanning instrument to scan the data of the exhaust system, and then Use reverse software to establish a digital model and compare it with the exhaust system design digital model to determine whether the product is qualified. These two methods are inefficient, cannot accurately or timely reflect the quality status of products, and cannot meet the increasingly high productivity requirements. the

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail. the

As shown in Figures 1 to 6, the on-line detection and inspection fixture of the automobile exhaust system of the present invention is provided with a detection reference block 4 on the bottom plate 1, and is also provided with a plurality of inspection blocks 3 corresponding to the pipes of the automobile exhaust system. , the position and size of the reference block 4 and the inspection block 3 should correspond to the shape and size of the standard product of the automobile exhaust system. The base plate is provided with a cylinder fixing block for fixing the cylinder (not shown in the figure), and the cylinder compresses the product to be tested. the

The cylinder fixing block, the detection reference block and the inspection block are respectively fixed on the bottom plate by bolts and positioning pins. the

In this embodiment, handles 2 are provided on opposite sides of the base plate 1 to facilitate moving the base plate 1 . the

There should be at least three inspection blocks 3 to ensure the correctness and accuracy of the inspection effect. In the present embodiment, there are five test blocks, and their positions and sizes correspond to the shape and size of standard exhaust system products respectively, which can ensure the accuracy of the test results. the

The working principle of the utility model is:

When testing, the product 6 to be tested is positioned on the test reference block 4 of the test fixture with the positioning pin 5, and one end of the test product 6 is pressed against the reference block 4 by the cylinder, and the rest is stuck in each test block. Gaps, vernier calipers or feeler gauges detect the gap between the product 6 and the inspection block 3, detect in real time during the production process, and adjust the product in real time to make it meet the requirements of standard products and ensure product quality. the

The above only illustrates several specific embodiments of the present utility model, but it cannot be regarded as the protection scope of the present utility model. Any equivalent change or modification made according to the design spirit of the present utility model shall be considered as falling within the scope of this utility model. Protection scope of utility model. the
