[0025] Reference Figures 1-5 As shown, this utility model provides a carbon fiber testing bracket.

[0026] Example 1 like Figure 1 As shown, including A carbon fiber base plate 1, with an inspection port 2 in the middle of the carbon fiber base plate; Carbon fiber support rod 3, several carbon fiber support rods are vertically arranged and distributed around the perimeter of the detection port; the bottom end of the carbon fiber support rod is fixed to the carbon fiber base plate. The carbon fiber horizontal frame 4 has several first connectors 5 installed in the carbon fiber horizontal frame by embedding or bonding. The several carbon fiber horizontal frames are fixedly connected to the carbon fiber support rod at intervals in the vertical direction through the first connectors. Several bonding planes are provided on both the carbon fiber support rod and the carbon fiber horizontal frame, and several marking points for identification by the scanning device are provided on the bonding planes.

[0027] In the above structure, a carbon fiber base plate is provided and fixedly installed on the external base 6, serving as the mounting surface for the carbon fiber detection frame. Multiple carbon fiber support rods are vertically fixed on the carbon fiber base plate, serving as the support structure for the detection bracket and used to fix the carbon fiber horizontal frame at different heights. The first connector serves as the connection between the carbon fiber horizontal frame and the carbon fiber support rods. The first connector is fixed to the carbon fiber horizontal frame by inlay or adhesive bonding, making the first connector and the carbon fiber horizontal frame integrally formed, thus preventing deformation due to external vibration or temperature changes after installation.

[0028] Based on the above structure, when using the carbon fiber inspection bracket to perform three-dimensional scanning measurement on workpiece 13 (the workpiece in the embodiment shown in the figure is a brake disc), the existing characteristics of carbon fiber material—light weight and no significant deformation when temperature changes—combined with the layered modular design of the carbon fiber horizontal frame and the integrated connection method of embedding or bonding the first connector to the carbon fiber horizontal frame, effectively reduce the problem of deformation of the inspection bracket caused by external temperature changes or vibrations. This eliminates the influence of ambient temperature changes on the accuracy and stability of the measurement, and also minimizes the influence of external vibration sources on the measurement, thereby improving the measurement accuracy of the workpiece.

[0029] Example 2 Based on Example 1, two preferred structural forms of carbon fiber horizontal frames are given, specifically, The first category, such as Figure 1-4As shown, the carbon fiber horizontal frame includes several carbon fiber rods. The first connector has two connecting parts 7 and one fastening part 8. The carbon fiber rods are fixedly connected to each other through the first connector to form an integral part. The adjacent ends of two carbon fiber rods are respectively embedded and fixed or glued to the two connecting parts of the first connector. The fastening part of the first connector is fastened and fixed to the carbon fiber support rod.

[0030] In the first embodiment, the first connector has two connecting parts for adhesive or inlay fixation, which simultaneously connect two adjacent carbon fiber rods. The carbon fiber rods are connected to each other through the first connector to form a ring-shaped integral component.

[0031] The second category, such as Figure 5 As shown, the carbon fiber horizontal frame includes several carbon fiber rods and a second connector. Both the first connector and the second connector include a connecting part and a fastening part. The several carbon fiber rods are fixedly connected by the second connector to form a whole, and the whole is fixed to the carbon fiber support rod by the first connector.

In this second type of embodiment, after the carbon fiber rod is manufactured in the factory, and the first or second connector is glued or embedded to the end of the carbon fiber rod, the carbon fiber horizontal frame can be assembled on-site by operators.

[0038] In embodiments 1-3, preferably, both the carbon fiber rod and the carbon fiber support rod are straight rods with polygonal cross-sections. Marking points are affixed to a plane of the support rod.

[0039] In embodiments 1-3, a handle 11 is provided on the carbon fiber base plate to facilitate the taking and placing of the carbon fiber testing bracket.

The first connecting part includes an L-shaped body. Pipe joints are provided as connecting parts in both the transverse and longitudinal sections of the L-shaped body. The pipe joints located in the transverse section and the pipe joints located in the longitudinal section are perpendicular to each other. A clamp is provided at the end of the transverse or longitudinal section as a fastening part. The clamp is fixed to the carbon fiber support rod by fasteners. It also includes several carbon fiber straight rods and a third connector. The third connector includes two fastening parts. The carbon fiber straight rods are fastened and fixed to the two carbon fiber horizontal frames by the third connector. The carbon fiber straight rods are arranged vertically, and the center lines of the two fastening parts of the third connector are perpendicular to each other.

[0043] During the scanning process of the same batch of components, after the initial calibration, the components to be scanned are replaced sequentially from the detection port via a lifting platform until all components in the batch have been scanned.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description.
