Description

Technical Field

[0001] The utility model relates to the technical field of clamping mechanisms, and more specifically, to a clamping mechanism for round steel processing. Background Art

[0002] The clamping mechanism for round steel processing is a device used to fix and clamp round workpieces. It usually consists of a clamping claw, a clamping seat and a control system. The clamping claw is designed to move around the round workpiece and apply enough pressure to keep the workpiece in a stable position during processing. This mechanism can be used on lathes, milling machines or other processing equipment to ensure that the round steel maintains the correct position and direction during processing. In the process of round steel processing, the clamping device is one of the most important background technologies. At present, the existing clamping devices are mainly based on single-point clamping and fixing, which leads to the problem of poor fixing effect of round steel during processing. In addition, these devices are not very convenient for quickly selecting clamping blocks of different sizes according to the different diameters of the round steel, which brings certain inconveniences to the processing operation. In this context, seeking a more effective clamping device technology has become an important direction for improving the efficiency and convenience of mechanical polishing of round steel.

[0003] At present, in order to make the clamping of round steel more stable, more emphasis is placed on maintaining stability by clamping the two ends of the pipe fitting. The contact surface between the clamp and the end of the pipe fitting is usually equipped with a rubber plate to protect the pipe fitting. However, the round steel will cut and wear the rubber plate during the clamping process, so the rubber plate at the end of the clamp needs to be replaced regularly. The current rubber mechanism is usually fixed by bonding or screwing, but both designs have certain inconveniences during the disassembly process. In this context, seeking a rubber mechanism design that is more convenient to disassemble and more economical and durable has become a key technical challenge for improving the clamping mechanism.

[0004] After the round steel is fixed, processing operations must be carried out. However, the existing processing equipment lacks the ability to flexibly adjust the height of the round steel, which leads to serious limitations in the loading and processing process. Since the processing equipment cannot be adjusted to a sufficient height, the processing operation is seriously affected, which may lead to a decrease in processing accuracy and production efficiency. Therefore, solving this problem has become one of the technical challenges that urgently need to be broken through in the current round steel processing field. It is necessary to seek a design and improvement of equipment that can flexibly and accurately process round steels of different diameters. Summary of the invention
