Description

Technical Field

[0001] This utility model mainly relates to the field of automotive testing technology, specifically to a carbon fiber testing fixture. Background Technology

[0002] In the process of automobile production, the various parts are generally formed by die casting and then welded together. After welding, the body needs to be measured for dimensional tolerances. If the tolerances are too large, it will cause the subsequent automobile parts to be unable to be installed.

[0003] For example, after a car is assembled, there will be concave slots at the welded joints of the body sheet metal to install other parts. These concave slots need to meet certain dimensional requirements, and generally, the dimensional tolerances of the concave slots at the welded joints of the body sheet metal need to be inspected using inspection fixtures.

[0004] During the operation of specific embodiments, the inventors discovered the following defects:

[0005] Most current testing fixtures are made of metal, which makes them quite heavy. When using them, it often requires two people to lift the fixture to the concave slot on the windshield. Moreover, the excessive weight may put too much pressure on the sheet metal, causing scratches and bumps on the concave slot.

[0006] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0037] See attached document Figure 1-6A carbon fiber testing fixture comprises symmetrically arranged first carbon fiber tubes 1 and spaced-apart second carbon fiber tubes 2. The first carbon fiber tubes 1 and the second carbon fiber tubes 2 are joined at the corners by L-shaped connecting blocks 3 to form a frame structure. The middle of the first carbon fiber tube 1 is connected to one end of a first connecting member 4, and the other end of the first connecting member 4 is connected to a third carbon fiber tube 5. The middle of the two third carbon fiber tubes 5 are connected by a first connecting ball 6. The four sides of the first connecting ball 6 are connected to one end of a fourth carbon fiber tube 7. The other end of the fourth carbon fiber tube 7 is connected to the L-shaped connecting block 3 by a second connecting member 8. Different testing sliders 9 are detachably connected to the first carbon fiber tubes 1 and the second carbon fiber tubes 2. This device can be assembled according to the contour of the car body to be tested. Therefore, various carbon fiber rods of different specifications can be selected according to different vehicles and assembled by L-shaped connecting blocks 3. Since this assembly uses carbon fiber material, it not only has high structural strength but also light weight, which can be lifted by a single person for testing. During testing, the testing sliders 9 are loaded according to the concave slots of different cars. The third carbon fiber tubes 5 and the fourth carbon fiber tubes 7 can increase the overall structural strength.

[0038] The top of the first connecting ball 6 is connected to the symmetrically arranged second connecting ball 62 through the fifth carbon fiber tube 61.

[0039] On the same side, the sixth carbon fiber tube 63, which is connected to the L-shaped connecting block 3, is provided with a carbon fiber gripping handle 64. The carbon fiber gripping handle 64 makes it easy for the testing personnel to pick up and put down the entire device, and the carbon fiber material can also reduce the overall weight.

[0040] The bottom of the detection slider 9 has a concave groove 91, which matches and connects to each carbon fiber tube. The bottom of the detection slider 9 is connected to the carbon fiber tube via a concave snap-fit ​​connector 92. The top of the detection slider 9 has multiple first threaded holes 93, which are detachably connected to the detection assembly 94. The detection slider 9 can be connected to different detection assemblies 94 by screws, which facilitates subsequent detection operations. The concave snap-fit ​​connector 92 and the detection slider 9 can be moved and fixed on the carbon fiber tube, which is convenient for adapting to different vehicle models and has strong adaptability.

[0041] The L-shaped connecting block 3 has a second threaded hole 31 at its top. The second threaded hole 31 can be detachably connected to the arc-shaped detection component 32, which facilitates the detection of the corner of the measuring concave groove.

The other end of the cylindrical block 41 is connected to a spherical slider 42, which has a through hole 43 for sliding connection with the first carbon fiber tube 1. The first connecting component 4 facilitates the connection between the first carbon fiber tube 1 and the third carbon fiber tube 5, and the whole is made of carbon fiber material, making the structure lightweight.

[0043] The first connecting ball 6 and the second connecting ball 62 have a notch at one end, and a first connecting hole 65 is opened on the opposite side of the notch. The first connecting hole 65 is connected to the fifth carbon fiber tube 61 by a screw. The first connecting ball 6 and the second connecting ball 62 have second connecting holes 66 distributed at intervals on their four sides. The second connecting holes 66 are connected to the fourth carbon fiber tube 7 and the sixth carbon fiber tube 63 by screws. The second connecting holes 66 on the connecting balls are designed according to the connection angle with other carbon fiber tubes. The screws are placed at the notch to connect with other connections, which is suitable for the manufacture of different fixtures.

[0044] The second connector 8 includes a first connecting post 81, with a connecting ball 82 rotatably connected to the outer side of the first connecting post 81. The connecting ball 82 has a concave connecting hole 83 at its bottom and a mounting groove 84 at its top. The L-shaped connecting block 3 has a corresponding concave groove 85, and a third threaded hole 86 is provided in the concave groove 85. To facilitate the connection and installation of the carbon fiber tube and the L-shaped connecting block 3, a second connector 8 is provided. One end of the second connector 8 is connected to the carbon fiber tube, and the other end is placed in the concave groove 85. The concave connecting hole 83 and the third threaded hole 86 are connected by screws. The connecting ball 82 can rotate on the first connecting post 81 to adapt to connection operations at different angles.

[0045] A detachable connecting component 10 is provided at the end of the carbon fiber tube. The connecting component 10 includes a carbon fiber convex threaded block 101, which can be inserted into the carbon fiber tube. The carbon fiber convex threaded block 101 has four fourth threaded holes 102 on its four sides, and the carbon fiber tube has a corresponding fifth threaded hole 103. The carbon fiber convex threaded block 101 is detachably connected to a carbon fiber plug 104, and the outer end of the carbon fiber plug 104 has a sixth threaded hole 105. To reduce overall weight, the carbon fiber tube is hollow, but this design makes it difficult to connect with other components. Therefore, the connecting component 10 is designed to address this issue. When installing the connecting component 10 at both ends of the carbon fiber tube, first place the carbon fiber convex threaded block 101 into the carbon fiber tube, and connect the fourth threaded hole 102 and the fifth threaded hole 103 with screws to complete the fixing of the convex threaded block. Then, rotate the carbon fiber plug 104 into the convex threaded block so that the carbon fiber plug 104 is flush with the end of the carbon fiber tube. Subsequently, the sixth threaded hole 105 can be used to connect with other connecting components. In this embodiment, the connecting component 10 is provided at the intersection of the fourth carbon fiber tube 7, the fifth carbon fiber tube 61, the sixth carbon fiber tube 63 with the first connecting ball 6 and the second connecting ball 62.

[0046] The sixth threaded hole 105 is connected to other structures with adhesive, which can improve the stability of the threaded connection.

However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
