Description

Technical Field

[0001] This utility model relates to the field of aluminum processing technology, specifically to a clamping arm device for aluminum rods. Background Technology

[0002] In the field of aluminum processing, aluminum rods, as a common metal material, often need to be fixed by clamping devices during processing or assembly.

[0003] Traditional aluminum bar clamping devices mostly use rigid clamps (such as metal jaws) to directly contact the surface of the aluminum bar, which has the following drawbacks:

[0004] 1. Easily damages the surface of aluminum rods: The hard contact between rigid clamps and aluminum rods can easily produce scratches or indentations, especially for aluminum rods with high surface requirements (such as aluminum rods after anodizing or spraying), which significantly increases the cost of subsequent polishing or repair.

[0005] 2. Insufficient friction: The smooth surface of the clamp is prone to slipping when in contact with the aluminum rod, especially during high-speed handling or tilting operations, which may cause the aluminum rod to fall off, posing a safety hazard.

[0006] Therefore, we propose a clamping arm device for aluminum rods. Utility Model Content

[0025] 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.

[0026] This embodiment is a clamping arm device for aluminum rods.

[0027] like Figure 1-4 As shown, the device includes a fixed block 1, with a connecting arm 2 fixedly connected to one end of the fixed block 1. The fixed block 1 has an installation cavity 10 inside, and a hydraulic rod 11, a tension sensor 12, and a movable block 13 are installed inside the installation cavity 10. Guide sleeves 9 are fixedly installed on the left and right ends of the upper outer surface of the fixed block 1, and the lower end of the guide sleeves 9 extends through to the upper part of the installation cavity 10. A lower clamp 3 is fixedly installed in the middle of the upper outer surface of the fixed block 1, and an upper clamp 4 is provided on the upper part of the lower clamp 3. Both the upper outer surface of the lower clamp 3 and the lower outer surface of the upper clamp 4 have arc-shaped grooves 14. A flexible coating 5 is provided in the arc-shaped grooves 14, and the clamping surface of the flexible coating 5 is provided with micro-protrusion texture 6. Connecting blocks 7 are fixedly installed on the outer surfaces of both ends of the upper clamp 4, and a movable shaft 8 is fixedly installed on the lower outer surface of the connecting block 7.

[0028] The cylinder of the hydraulic rod 11 is fixed in the middle of the lower end of the mounting cavity 10. The tension sensor 12 is fixed between the upper outer surface of the piston rod in the hydraulic rod 11 and the middle of the lower outer surface of the movable block 13. There are two sets of movable shafts 8 and guide sleeves 9. The two sets of movable shafts 8 pass through the two sets of guide sleeves 9 and are fixedly connected to the left and right ends of the upper outer surface of the movable block 13. The outer wall of the movable shaft 8 and the guide sleeve 9 are slidably connected. The micro-bump texture 6 is hemispherical, with a height of 0.5-2mm and a spacing of 1-3mm between adjacent micro-bumps. The flexible coating 5 is integrally formed with the micro-bump texture 6. The flexible coating 5 is made of polyurethane or rubber and has a thickness of 1-5mm.

[0029] It should be noted that this utility model is a clamping arm device for aluminum bars. The aluminum bar is placed between the lower clamp 3 and the upper clamp 4. The operation of the hydraulic rod 11 pulls the tension sensor 12. The tension sensor 12 drives the movable shaft 8 to slide along the guide sleeve 9. The movable shaft 8 drives the upper clamp 4 to descend, thereby clamping and fixing the aluminum bar between the lower clamp 3 and the upper clamp 4. The tension sensor 12 facilitates the monitoring of the pressure applied to the aluminum bar, preventing the hydraulic rod 11 from applying too much pressure and causing deformation of the aluminum bar. The flexible coating 5 and the micro-protrusion texture 6 are provided. The elastic buffering properties of the flexible coating 5 (such as polyurethane) can absorb local pressure and prevent the clamp from directly scraping the aluminum bar. It is particularly suitable for clamping high-gloss aluminum bars. The micro-protrusion texture 6 (such as hemispherical) increases the roughness of the contact surface, enhances friction, and prevents slippage. The connecting arm 2 described in the text can be installed on an external driving device, such as a robotic arm, to increase the flexibility of the clamping arm.
