Description

Technical Field

[0001] The utility model relates to the technical field of pipe clamping devices, in particular to an adjustable steel pipe clamping assembly. Background Art

[0002] At present, when processing steel pipes, steel pipe production lines need to position and clamp the steel pipes to ensure that the steel pipes are firmly positioned. In order to reduce the difficulty of clamping the steel pipes, the existing technology uses a clamping cover and a clamping seat connected by an axle pin to directly clamp the steel pipes, thereby achieving the purpose of simple and quick clamping.

[0003] For example, the Chinese patent application number CN201822080730.3 discloses a steel pipe clamping and fixing device, which uses the horizontal movement of the guide block in the guide groove to adjust the distance between the two guide blocks. At the same time, by conveniently replacing different types of clamping mechanisms on the pad, it helps to clamp and fix different types of steel pipes, which helps to provide convenience for steel pipe fixation; at the same time, by stably connecting the guide block, the clamping cover and the clamping seat, the stability of the steel pipe clamping is ensured. However, when in use, this device can only effectively clamp a single steel pipe, but there are usually batches of steel pipes that need to be processed in the steel pipe production line. The clamping and disassembly of a single steel pipe each time greatly affects the processing efficiency. Utility Model Content
