Description

Technical Field

[0001] This utility model relates to the technical field of rock testing equipment, and in particular to a clamping and positioning device for rock testing. Background Technology

[0002] Hardness is one of the important physical properties of rocks. Hardness tests can help geologists classify and identify rocks. Different types of rocks have different hardness ranges. For example, granite has a higher hardness, while shale has a relatively lower hardness. Based on the results of hardness tests, combined with other geological characteristics, rock types can be identified more accurately, providing basic data for geological structure research and mineral resource exploration.

[0003] When conducting rock strength tests, rock samples must be securely clamped and positioned to ensure the accuracy and reliability of test data. Currently, existing rock testing clamping and positioning devices generally have some limitations. On the one hand, some devices have relatively simple structural designs, making it difficult to quickly and accurately clamp rock samples of different shapes and sizes. When dealing with irregular rock samples, the fixing effect is poor, easily leading to displacement or loosening of the rock sample during the test, affecting the accuracy of the test results. On the other hand, traditional clamping and positioning devices have limited adjustment functions, unable to flexibly adjust the angle and height of the rock sample, making it difficult to meet complex and diverse test requirements, greatly limiting test efficiency and research depth. Furthermore, the stability and reliability of some devices gradually decrease during long-term use, with problems such as structural wear and loosening, increasing test costs and equipment maintenance difficulty.

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Reference Figures 1 to 5 As shown, this utility model provides a technical solution: a clamping and positioning device for rock testing, including a base plate 1, a fixing frame 2 fixedly connected to the surface of the base plate 1, a rotating ring 8 rotatably connected to the inner wall of the fixing frame 2, an arc-shaped groove 9 opened on the surface of the rotating ring 8, a sliding column 12 slidably connected to the inner wall of the arc-shaped groove 9, a sliding frame 11 fixedly connected to both ends of the sliding column 12, and a limiting block 13 fixedly connected to one side of the sliding frame 11. By rotating the rotating ring 8, the sliding column 12 can be driven to slide in the arc-shaped groove 9, thereby driving the limiting block 13 on the sliding frame 11 to fix rock samples of different sizes, achieving the effect of quickly fixing rock samples and improving the efficiency of the experiment.

[0027] Reference Figure 3 , Figure 4 and Figure 5As shown in this embodiment: the number of arc-shaped grooves 9 is set to three sets, and they are evenly opened on the surface of the rotating ring 8. By setting three sets of arc-shaped grooves 9, three limiting blocks 13 can be driven simultaneously to fix the rock sample from different directions, improving the stability of the rock sample fixation. A mounting part 17 is provided on one side of the fixing frame 2. A worm gear 18 is rotatably connected to the surface of the mounting part 17. A worm wheel ring 10 is meshed with the surface of the worm gear 18. The worm wheel ring 10 is fixedly connected to the outer wall of the rotating ring 8. By rotating the worm gear 18, the gear ring can be driven to rotate, and the gear ring can be driven to rotate the rotating ring 8, thereby achieving the effect of driving the sliding frame 11 to move. A guide groove 14 is opened on the surface of the sliding frame 11. A guide block 16 is slidably connected to the inner wall of the guide groove 14. The surface of the guide block 16 is fixedly connected to the surface of the fixed plate 15, and one end of the fixed plate 15 is fixedly connected to the surface of the fixed frame 2. By setting the guide groove 14 and the guide block 16, the sliding frame 11 can move more smoothly when driving the limit block 13, thereby improving the stability of the device. One end of the worm gear 18 is fixedly connected to the driven gear 19, and the surface of the driven gear 19 is meshed with the driving gear 20. The driving gear 20 is rotatably connected to the surface of the fixed frame 2, and one side of the driving gear 20 is fixedly connected to the handle B21. By rotating the handle A7, the driving gear 20 can be driven to rotate. By rotating the driving gear 20, the driven gear 19 can be driven to rotate, thereby achieving the effect of driving the worm gear to rotate.

[0028] Reference Figure 1 and Figure 2 As shown, specifically, a placement frame 3 is provided below the rotating ring 8. A movable frame 4 is fixedly connected to the lower end of the placement frame 3. One end of the movable frame 4 is rotatably connected to a threaded rod 5, and the other end of the movable frame 4 is threadedly connected to a threaded rod 5. A mounting base 6 is fixedly connected to the lower end of the movable frame 4. The lower surface of the mounting base 6 is fixedly connected to the surface of the base plate 1. A throttle A7 is fixedly connected to one end of the threaded rod 5. After the rock sample is placed into the placement frame 3, the threaded rod 5 can be rotated by rotating the throttle B21. At the same time as the threaded rod 5 rotates, the movable frame 4 rotates by means of the thread, thereby adjusting the placement height of the placement frame 3. This allows the rock sample to be fixed at different positions, improving the stability of the device.

[0029] Working principle: During use, the rock sample is placed in the placement frame 3. Rotating the handle A7 drives the threaded rod 5 to rotate, allowing the movable frame 4 to adjust the height of the placement frame 3 via threaded transmission to accommodate different positions of the rock sample. After adjustment, rotating the handle B21 drives the drive gear 20 to rotate. The drive gear 20 drives the driven gear 19, which in turn drives the worm 18 to rotate. The worm 18 meshes with the worm wheel ring 10, causing the worm wheel ring 10 to drive the rotating ring 8 to rotate. The rotating ring 8 has three sets of evenly spaced arc-shaped grooves 9 on its surface. When the sliding column 12 is moved, it slides along the groove, which in turn moves the sliding frame 11 fixed at both ends. The limiting block 13 on one side of the sliding frame 11 quickly fixes the rock sample from different directions. At the same time, the guide groove 14 on the surface of the sliding frame 11 cooperates with the guide block 16 on the fixing plate 15 to ensure that the sliding frame 11 moves smoothly with the limiting block 13, and to ensure that the rock sample is fixed and stable. Finally, it realizes the rapid and stable multi-angle and multi-position clamping and positioning of the rock sample, meets the diverse needs of rock tests, and improves test efficiency and data accuracy.
