The force sensor and displacement measurement component collect data in real time. During operation, the electronic universal testing machine drives the loading, and the data is transmitted to the control system to precisely control the loading process and realize automated pull-out testing.

[0004] Currently, some electronic universal testing machines lack an automatic docking and disassembly structure between the pull-out head and the pull column fixed inside the material when performing pull-out tests. This increases the preparation time for pull-out tests and affects work efficiency. Therefore, an improved pull-out testing device based on an electronic universal testing machine is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a pull-out testing device based on an improved electronic universal testing machine, aiming to improve the problem of the lack of an automatic disassembly and assembly structure between the pull-out head and the pull column in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pull-out testing device based on an improved electronic universal testing machine includes a housing, a limiting component inside the housing, a slide rail fixedly connected to the top of the housing, a sliding plate slidably connected inside the slide rail, a fixing frame fixedly connected to the top of the housing, a locking component inside the fixing frame, a fixing block fixedly connected to the bottom of the sliding plate, a limiting block slidably connected inside the fixing block, a telescopic column fixedly connected to the outside of the limiting block, a spring sleeved on the outside of the telescopic column, a test block at the top of the housing, a fixing column fixedly connected to the top of the test block, a fixing cone fixedly connected to the top of the fixing column, a movable cone slidably connected to the outside of the fixing column, and a fixing ring fixedly connected to the outside of the fixing column.

[0012] As a further description of the above technical solution:

[0013] The locking assembly includes a threaded post, the external thread of which is connected to the interior of the fixing frame, and a pressing block is fixedly connected to the bottom end of the threaded post;

[0014] As a further description of the above technical solution:

[0015] The limiting component includes a motor, which is externally fixedly connected to the inside of the housing. A rotating rod is fixedly connected to the drive end of the motor. Two transmission rods are rotatably connected inside the rotating rod. A sliding block is rotatably connected to the far end of each of the two transmission rods. A connecting block is fixedly connected to the top of each of the two sliding blocks. A fixing plate is fixedly connected to the top of each of the two connecting blocks.

[0016] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:

[0023] 1.

[0024] 2. In this utility model, when performing a pull-out test, the test block is placed on the top of the housing, the motor is started to drive the rotating rod, and the sliding block is driven to slide through the transmission rod.

This process quickly adjusts and restricts the position of the test block, avoiding the impact of positional deviation on the test results. At the same time, it facilitates the assembly and handling of the test block, greatly improving work efficiency. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a pull-out testing device based on an improved electronic universal testing machine, comprising a housing 1, which serves as the basic support structure of the entire device. The housing 1 has a limiting component inside, which can precisely adjust and fix the position of the test block 15, improving the accuracy of the test. A slide rail 9 is fixedly connected to the top of the housing 1, and a sliding plate 10 is slidably connected inside the slide rail 9. The sliding plate 10 can slide up and down on the slide rail 9 to achieve the pull-out operation of the test block 15. A fixing frame 2 is fixedly connected to the top of the housing 1, and a locking component is provided inside the fixing frame 2 to firmly lock the test block 15, ensuring the stability of the test block 15 during the test. A fixing block 11 is fixedly connected to the bottom of the sliding plate 10, serving as an important component connecting the sliding plate 10 and the fixing column 16. A limiting block 12 is slidably connected inside the fixing block 11, and the limiting block 12 can slide within the fixing block 11 to limit and fix the fixing cone block 18.

[0033] A telescopic column 13 is fixedly connected to the outside of the limiting block 12. The telescopic column 13 can extend and retract when the limiting block 12 moves. A spring 14 is sleeved on the outside of the telescopic column 13, providing support and guidance for the spring 14. The spring 14 is compressed when the limiting block 12 moves, generating thrust to achieve automatic locking and unlocking of the fixed cone block 18. A test block 15 is provided at the top of the housing 1. The test block 15 is the object to be tested in a pull-out test. A fixed column 16 is fixedly connected to the top of the test block 15. The fixed column 16 is used to connect the fixed cone block 18 and the moving cone block 19, realizing the connection between the test block 15 and the fixed block 11. A fixed post is fixedly connected to the top of the fixed column 16. The fixed cone block 18 and the fixed column 16 are externally fixedly connected to a fixed ring 17. The fixed column 16 is externally slidably connected to a movable cone block 19. The movable cone block 19 can slide on the fixed column 16 and cooperate with the fixed cone block 18 to lock and unlock the fixed block 11. The locking component includes a threaded column 20. The external thread of the threaded column 20 is connected to the inside of the fixed frame 2. By rotating the threaded column 20, the extrusion block 21 can be moved up and down to achieve precise fixation of the test block 15. The bottom end of the threaded column 20 is fixedly connected to the extrusion block 21. The extrusion block 21 can fit tightly with the test block 15 to ensure that the test block 15 will not be displaced during the test.

[0034] Reference Figure 1 and Figure 2 The limiting component includes a motor 3, which is externally and fixedly connected to the inside of the housing 1. A rotating rod 4 is fixedly connected to the drive end of the motor 3. Two transmission rods 5 are rotatably connected inside the rotating rod 4. Sliding blocks 6 are rotatably connected to the opposite ends of the two transmission rods 5. The transmission rods 5 can convert the rotation of the rotating rod 4 into the linear motion of the sliding blocks 6. The sliding blocks 6 can slide inside the housing 1. Connecting blocks 7 are fixedly connected to the top of the two sliding blocks 6. Fixing plates 8 are fixedly connected to the top of the two connecting blocks 7. The fixing plates 8 are driven by the connecting blocks 7 to adjust the position of the test block 15. The outside of the fixing plates 8 is in contact with the outside of the test block 15. The device can adjust and fix the position of the test block 15, so that the test block 15 is centered. The top of the housing 1 has a sliding groove. The external part of the connecting block 7 is slidably connected to the inside of the sliding groove. The sliding groove can provide guidance for the sliding of the connecting block 7, ensuring that the connecting block 7 can accurately drive the fixed plate 8 to move. The external part of the sliding block 6 is slidably connected to the inside of the housing 1. The external part of the rotating rod 4 is rotatably connected to the inside of the housing 1, ensuring the stable rotation and sliding of the rotating rod 4 and the sliding block 6 within the housing 1. The external part of the slide rail 9 is fixedly connected to the control box 22, which can control the operation of the entire device and realize the precise operation of the pull-out test.

[0035] Working principle: When the operator needs to perform a pull-out test on the test block 15, the test block 15, which is fixed with the fixing ring 17, is placed at the top of the housing 1. At this time, the motor 3 is started, and the motor 3 drives the rotating rod 4 to rotate, so that the transmission rod 5 pulls the sliding block 6 to slide inside the housing 1. This causes the connecting block 7 to drive the fixing plate 8 to adjust the position of the test block 15, so that the position of the test block 15 is centered and fixed. Then, by rotating the threaded column 20, the pressing block 21 moves downward and fits tightly with the test block 15, thereby accurately fixing the position of the test block 15. By quickly adjusting and restricting the position of the test block 15, it is ensured that the pull-out test results will not be affected by the position difference of the test block 15 during the subsequent pull-out process. At the same time, it is convenient to assemble and remove the test block 15, thus improving the efficiency of the work.

[0036] After the test block 15 is fixed in position, the sliding plate 10 moves downward inside the slide rail 9 by driving the slide rail 9. When the sliding plate 10 moves downward, the outside of the fixed block 11 passes through the hole inside the fixing frame 2, and the outside of the fixed cone 18 slides inside the fixed block 11. When the fixed cone 18 slides inside the fixed block 11, it will squeeze the limiting block 12, thereby causing the limiting block 12 to slide inside the fixed block 11. At this time, the spring 14 will be compressed, thereby generating a thrust. When the fixed cone 18 slides to the designated position inside the fixed block 11, the spring 14 will automatically push the limiting block 12 to slide to the bottom of the fixed cone 18. At this time, the fixed block 11 and the fixed post 16 are assembled. Once the slide rail 9 is driven in reverse, the pull-out test begins. After the test, the slide rail 9 is driven downwards again, causing the limiting block 12 to be pressed by the moving cone 19, thus sliding back into the interior of the fixed block 11. Then, the slide rail 9 is driven upwards, causing the moving cone 19 to slide outside the fixed column 16 under the push of the limiting block 12. When the moving cone 19 contacts the fixed cone 18, the fixed block 11 will slide normally outside the fixed cone 18 and the moving cone 19, thus causing the fixed cone 18 to slide out from inside the fixed block 11, completing the disassembly. Through the automatic mechanical structure, the fixed block 11 and the fixed column 16 can be quickly disassembled and assembled, improving the efficiency of the test.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
