Description

Technical Field

[0001] The invention relates to the technical field of electric fusion pipe fitting production, and in particular to an electric fusion pipe fitting processing clamping device. Background Art

[0002] Electric fusion pipe fittings refer to polyethylene pipe fittings that can be melted by the temperature generated by electric current to achieve connection. Capacity is the main parameter. In some low-voltage circuits, the voltage requirement is not high, and only the ampere number is required. When producing and processing electric fusion pipe fittings, it is necessary to use a clamping workpiece to clamp and fix the pipe fittings to facilitate subsequent processing and ensure processing quality.

[0003] The Chinese patent with the prior art authorization announcement number CN221561138U provides an electric fusion pipe production clamping device, which inserts the electric fusion pipe into the interior of the pipe clamping assembly, drives the ejector block structure through the micro-driving cylinder inside the clamping sleeve assembly in the pipe, so that the ejector block structure is close to the ejector rod structure, and one end of the ejector rod structure is set as an inclined surface, and the ejector rod structure is ejected out of the clamping sleeve assembly in the pipe by the ejector block structure, so that the other end of the ejector rod structure is against the inner wall of the electric fusion pipe to fix it, when the micro-driving cylinder shrinks, the ejector block structure is away from the ejector rod structure, and the spring structure on the ejector rod structure rebounds and resets, so that the ejector rod structure is retracted into the clamping sleeve assembly in the pipe, so that the clamping sleeve assembly in the pipe loses the fixation to the electric fusion pipe, in summary, the outer wall and the inner wall of the electric fusion pipe are doubly clamped and fixed, thereby enhancing the stability of the electric fusion pipe during processing.

[0004] Although the above patent can clamp the electrofusion pipe fitting, when only one end of the electrofusion pipe fitting needs to be processed, clamping both ends at the same time will be inconvenient for processing, and if the electrofusion pipe fitting is too long, clamping both ends at the same time will cause the clamping device to be too large and inconvenient to use.
