Description

Technical Field

[0001] The utility model relates to the technical field of pipeline processing equipment, and particularly relates to a pipeline synchronous clamping device. Background Technique

[0002] During the processing of metal pipelines (such as stainless steel composite pipelines), it is usually necessary to clamp the pipelines. Currently, the clamping parts of the pipeline synchronous clamping device are usually set as two identical clamping jaws, and the clamping jaws are set as fixed structures. During the clamping process, only pipe fittings with a pipe diameter within a certain numerical range can be clamped, and pipe fittings with a smaller pipe diameter cannot be effectively clamped.

[0003] After retrieval, a synchronous clamping flying saw fixture device disclosed in Chinese Patent CN202877916U is the closest prior art. The scheme disclosed in this patent is provided with a synchronous clamping device, a left clamping block and a right clamping block, and the left clamping block and the right clamping block are driven by the synchronous clamping device to synchronously clamp the pipe fitting. The left clamping block and the right clamping block set in this patent are of the same arc structure. When clamping a pipe fitting with a smaller pipe diameter, the left clamping block and the right clamping block touch each other and cannot move further, resulting in the inability to effectively clamp the pipe fitting with a smaller pipe diameter, and it has the disadvantage of low versatility.
