Description

Technical Field

[0001] This utility model relates to the technical field of CT sample processing equipment, and in particular to a mistake-proof tooling for CT sample processing. Background Technology

[0002] Fracture mechanics testing plays a crucial role in many fields such as aerospace, automotive manufacturing, and energy engineering. As a key indicator for evaluating a material's resistance to crack propagation, CT specimens are widely used in these fields due to their standardization and representativeness.

[0003] Traditional fracture toughness processing methods generally suffer from low repeatability, poor quality stability, complex operation, and susceptibility to errors. These problems not only reduce processing efficiency but may also lead to deviations and defects in the specimens during processing, severely affecting the accuracy of the tested structures. Therefore, a mistake-proof fixture for CT-type specimen processing is proposed to address these issues. Utility Model Content

[0004] The main purpose of this utility model is to provide a foolproof tooling for processing CT type samples, which can effectively solve the technical problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A fault-prevention fixture for CT sample processing includes an equipment workbench and a support platform, wherein a positioning mechanism is provided on the outside of the support platform;

[0007] The positioning mechanism includes a CT sample and a positioning stage. The positioning stage and the bearing platform are fixedly connected. The positioning stage is connected to the equipment workbench through two tooling fixing holes and bolts. Several positioning pins are fixedly installed on the top of the bearing platform, and several locking bolt holes are opened on the top of the bearing platform.

[0008] As a further embodiment of this utility model, the top of the positioning platform has two tooling fixing bolt holes, and the threads of the tooling fixing bolts and the tooling fixing bolt holes are compatiblely matched.

[0009] As a further embodiment of this utility model, the top of the bearing platform is provided with several clearance grooves, and the top of the CT sample is provided with two sample loading holes.

[0010] As a further embodiment of this utility model, the top of the bearing platform is provided with an adjustment mechanism, the adjustment mechanism includes a pressure plate, the top of the pressure plate is provided with a through hole and an adjustment bolt hole, the through hole is connected to a locking bolt by a thread, and the locking bolt is connected to a locking screw by a thread.

[0011] As a further embodiment of this utility model, the adjusting bolt hole is connected to an adjusting bolt via a thread, and the thread of the locking bolt and the thread of the locking bolt hole are compatiblely matched.

[0012] As a further embodiment of this invention, the sample loading hole of the CT sample and the positioning pin at the corresponding position are adaptively matched.

[0013] The beneficial effects of this utility model are as follows:

[0014] By combining the positioning mechanism and the adjustment structure, the machining accuracy can be significantly improved.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figure 1-4 As shown, a fault-prevention tooling for CT sample processing includes an equipment workbench 15 and a support platform 10, with a positioning mechanism provided on the outside of the support platform 10.

[0022] The positioning mechanism includes a CT sample 3 and a positioning platform 12. The positioning platform 12 and the bearing platform 10 are fixedly connected. The positioning platform 12 is connected to the equipment workbench 15 through two tooling fixing hole bolts 16. Several positioning pins 1 are fixedly installed on the top of the bearing platform 10, and several locking bolt holes 13 are opened on the top of the bearing platform 10.

[0023] The positioning pin 1 is used to precisely fit with the loading hole of the sample to ensure accurate positioning of the sample, and the equipment worktable 15 serves as a basic support.

[0024] In this embodiment, the top of the positioning platform 12 has two tooling fixing bolt holes 11, and the threads of the tooling fixing bolt 16 and the tooling fixing bolt holes 11 are compatible.

[0025] The tooling fixing bolt hole 11 mates with the tooling fixing bolt 16 to fix the positioning table 12.

[0026] In this embodiment, the top of the support platform 10 is provided with several clearance grooves 2, and the top of the CT sample 3 is provided with two sample loading holes 4.

[0027] Positioning pin 1, in conjunction with sample loading hole 4, positions CT sample 3.

[0028] In this embodiment, the top of the bearing platform 10 is provided with an adjustment mechanism, which includes a pressure plate 5. The top of the pressure plate 5 is provided with a through hole 6 and an adjustment bolt hole 7. The through hole 6 is connected to a locking bolt 8 by a thread, and the locking bolt 8 is connected to a locking screw 14 by a thread.

[0029] The CT sample 3 can be positioned and pressed by using the locking bolt 8, adjusting bolt 9, and locking screw 14.

[0030] In this embodiment, the adjusting bolt hole 7 is connected to the adjusting bolt 9 by a thread, and the threads of the locking bolt 8 and the locking bolt hole 13 are compatiblely matched.

[0031] Adjusting bolt 9 can adjust the height of pressure plate 5.

[0032] In this embodiment, the sample loading hole 4 of the CT sample 3 and the positioning pin 1 at the corresponding position are adaptively matched.

[0033] The positioning pin 1 provides a limiting constraint for the CT sample 3.

[0034] It should be noted that this utility model is a foolproof tooling for CT sample processing. When in use, it can be placed in the work site to achieve the working conditions.

[0035] First, place the support platform 10 on the equipment workbench 15 through the positioning table 12, and ensure that the positioning table 12 is in close contact with the equipment workbench 15. Then, fix the positioning table 12 firmly on the equipment workbench 15 through the tooling fixing hole bolts 16 to prevent movement or vibration during processing.

[0036] The processed CT sample 3 is placed on the support platform 10, and the sample loading hole 4 is precisely aligned with the positioning pin 1 to ensure the stability and accuracy of the CT sample 3 during the processing.

[0037] Pass the locking bolt 8 and adjusting bolt 9 through the through hole 6 and adjusting bolt hole 7 of the pressure plate 5 respectively. Gently screw the locking bolt 8 into the locking bolt hole 13. Then use the adjusting bolt 9 to adjust the height of the pressure plate 5. The adjusting bolt 9 mainly acts to make the pressure plate 5 parallel to the CT sample 3, or to make one end of the pressure plate 5 drop slightly until it gently presses the CT sample 3. During this process, avoid excessive pressure to prevent damage to the sample.

[0038] Tighten the locking bolt 8 with the locking screw 14 to ensure that the pressure plate 5 remains stable during processing. Then, start the processing equipment and process the CT sample 3 according to the predetermined processing parameters and procedures. During processing, closely monitor the position and condition of the CT sample 3 to ensure smooth processing.

[0039] After processing is complete, turn off the processing equipment and wait for it to stop completely. Then, loosen the locking bolt 8 to remove the pressure plate 5, and remove the processed CT sample 3 for further processing or testing.

[0040] Furthermore, the design of the clearance groove 2 helps reduce interference between the tooling and the equipment, improving the flexibility and adaptability of the tooling. The precise fit between the positioning pin 1 and the sample loading hole 4 ensures the stability and accuracy of the CT sample 3 during processing. The pin diameter and spacing of this tooling can be set in various ways, making it suitable for processing samples of various specifications.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
