[0025] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0026] Example 1: Please refer to Figures 1 to 7 This utility model provides a technical solution: a cylindrical clamp adaptable to different diameters, including a body 1. Two clamping blocks 2 are hinged inside the body 1. A rubber pad 3 is detachably connected to the inner side of each clamping block 2. A connecting frame 4 is bolted to the rear side of each clamping block 2, allowing the connecting frame 4 to be disassembled and replaced. A sliding groove 5 is provided inside the rear side of the connecting frame 4. Multiple slots 6 are provided on both the upper and lower sides of the inner wall of the sliding groove 5. A locking block 7 is engaged inside each slot 6. One end of the locking block 7 that engages with the slot 6 is slidably connected to... On the inner wall of the slide groove 5, the locking block 7 can slide inside the slide groove 5. The outer side of the locking block 7 is slidably connected to the slider 8, so that the locking block 7 can limit the slider 8. The slider 8 is slidably connected inside the slide groove 5, and the slide groove 5 plays a limiting role for the slider 8, so that the slider 8 can slide smoothly. The rear end of the slider 8 is fixedly connected to the connecting frame 2 9. The inner side of the connecting frame 2 9 is detachably connected to the rubber pad 21, so that the rubber pad 21 can be replaced. The rubber pad 3 and the rubber pad 21 are used to clamp the cylindrical workpiece.

[0027] When clamping a cylindrical workpiece, the upper and lower clamping blocks 7 are moved to the same side, allowing them to slide into the interior of the slider 8. This disengages the clamping blocks 7 from the groove 6. The connecting frame 2 9 is then pulled backward, causing the slider 8 to slide backward within the groove 5. The slider 8 then pulls the clamping blocks 7 backward. When the clamping blocks 7 reach the desired vertical position within the groove 6, they are reversed and engaged with the inside of the groove 6. This limits the slider 8, connecting frame 1 4, and connecting frame 2 9, resulting in a larger gap between rubber pad 1 3 and rubber pad 2 21. This enhances the clamping stability of the cylindrical workpiece and allows the fixture to accommodate cylindrical workpieces of different diameters and lengths, making it more economical to use.

[0028] Example 2: Based on Example 1, to facilitate the pulling of the locking block 7, two mounting slots 10 are formed inside the front end of the slider 8. The locking block 7 is slidably connected inside the mounting slots 10, which provide movement space for the locking block 7. A mounting piece 11 is fixedly connected to the side of the locking block 7 away from the slot 6. The mounting piece 11 is slidably connected inside the mounting slot 10, which limits the mounting piece 11, preventing it from shifting during sliding. A pull rope 12 is fixedly connected to the end of the mounting piece 11 away from the locking block 7. The pull rope 12 is slidably connected... The pull rope 12 is connected inside the mounting groove 10, which limits the pull rope 12 and allows it to slide smoothly. A pull block 14 is fixedly connected to the end of the pull rope 12 away from the mounting plate 11. The pull block 14 is used to pull the pull rope 12 to move. The pull block 14 is slidably connected inside the slider 8, which limits the pull block 14 and allows it to slide smoothly. An elastic element 13 is sleeved on the outside of the pull rope 12. One end of the elastic element 13 is fixedly connected to the inner wall of the mounting groove 10, and the other end of the elastic element 13 is fixedly connected to the mounting plate 11.

[0029] When it is necessary to pull the locking block 7, by pulling the pulling block 14 to move it to the rear, the pulling block 14 can drive one end of the pulling rope 12 to move to the rear, thereby causing the other end of the pulling rope 12 to pull the mounting piece 11 to move inward, so that the pulling rope 12 can pull the locking block 7 into the interior of the mounting groove 10, and the locking block 7 can disengage from the interior of the groove 6. Conversely, by releasing the pulling block 14, the elastic element 13 of the pulling block 14 can perform a reset movement, thereby causing the elastic element 13 to push the mounting piece 11 to move outward, thereby causing the mounting piece 11 to push the locking block 7 to engage with the interior of the groove 6.

[0030] Example 3: Based on Example 2, in order to facilitate the disassembly of rubber pad 3 and rubber pad 21, two slots 15 are provided on the inner side of clamping block 2. Insert block 16 is inserted into the slot 15. Connecting rod 17 is fixedly connected to the inner side of insert block 16. Connecting rod 17 is slidably connected to the inside of clamping block 2. The inner side of connecting rod 17 is fixedly connected to rubber pad 3, so that clamping block 2 and rubber pad 3 can be stably connected. Two slots 18 are provided on the inside of connecting frame 9. Insert block 19 is inserted into the slot 18. Insert block 19 is slidably connected to the inside of connecting frame 9. Connecting rod 20 is fixedly connected to the inner side of insert block 19. The other end of connecting rod 20 is fixedly connected to rubber pad 21, so that rubber pad 21 and connecting frame 9 can be stably connected.

[0031] When rubber pad 3 needs to be installed, by fitting rubber pad 3 to clamp block 2, connecting rod 17 and insert block 16 can slide inside clamp block 2, and the insert block 16 is deformed by being squeezed. After rubber pad 3 is fitted to clamp block 2, insert block 16 can perform a reset movement, thereby filling the interior of slot 15, so that rubber pad 3 can be stably installed. Conversely, it can be easily disassembled. When rubber pad 21 needs to be installed, by fitting rubber pad 21 to connecting bracket 2 9, connecting rod 20 and insert block 2 19 can slide inside connecting bracket 2 9, and the insert block 2 19 is deformed by being squeezed. After rubber pad 21 is fitted to connecting bracket 2 9, insert block 2 19 can perform a reset movement, thereby filling the interior of slot 2 18, so that rubber pad 21 can be stably installed. Conversely, it can be easily disassembled.

[0032] The working process of this utility model is as follows:

[0033] When a cylindrical workpiece needs to be clamped, by attaching the rubber pad 3 to the clamping block 2, the connecting rod 17 and the insert block 16 can slide inside the clamping block 2, and the insert block 16 is compressed and deformed. After the rubber pad 3 is attached to the clamping block 2, the insert block 16 can perform a reset movement, thereby allowing the insert block 16 to fill the interior of the slot 15, so that the rubber pad 3 can be stably installed. Subsequently, by attaching the rubber pad 21 to the connecting bracket 29, the connecting rod 2... 20 and the second insert 19 can slide inside the second connector 9, and the second insert 19 is squeezed and deformed. When the second rubber pad 21 is in contact with the second connector 9, the second insert 19 can perform a reset movement, thereby filling the inside of the second slot 18 with the second insert 19, so that the second rubber pad 21 can be stably installed. Then, by pulling the pull block 14 to move it to the rear, the pull block 14 can drive one end of the pull rope 12 to move to the rear, thereby allowing the other end of the pull rope 12 to pull the mounting piece 1. 1. Move inward, so that the pull rope 12 can pull the locking block 7 into the interior of the mounting groove 10, and the locking block 7 can disengage from the interior of the groove 6. Then, pull the connecting bracket 2 9 backward, so that the connecting bracket 2 9 can drive the slider 8 to slide backward inside the sliding groove 5, and then the slider 8 can pull the locking block 7 to move backward. When the locking block 7 moves to the vertical position of the groove 6 at the required position, by releasing the pull block 14, the elastic element 13 of the pull block 14 can perform a reset movement, and then the elastic element 13 can push the mounting piece 11 to move outward, and then the mounting piece 11 can push the locking block 7 to engage with the interior of this groove 6, and then the slider 8 can be limited, and the connecting bracket 1 4 and the connecting bracket 2 9 can be limited, and then the distance between the rubber pad 1 3 and the rubber pad 2 21 is larger, so that the clamping stability of the cylindrical workpiece is higher, and thus the fixture can adapt to the clamping needs of cylindrical workpieces of different diameters and lengths, and thus has better economic efficiency.
