Description

A High Precision Pipe Fitting Grooving Machine

technical field

The utility model belongs to the field of pipeline processing equipment, and relates to the technology of pipeline grooving, in particular to a high-precision pipe fitting grooving machine.

Background technique

Pipeline connection operations, such as the connection of tap water pipes and the connection of fire-fighting pipes, are widely used in connection methods such as threaded connection, flange connection, welding, etc. Among them, the threaded connection is usually processed with a taper on the outer circumference of the pipe end. Threaded, the pipes are connected together through threaded pipe joints, which are mostly used in pipe connections with small pipe diameters; while flange connections are usually used in the case of large pipe diameters and relatively high pressure inside the pipes. In order to fix a flange at the pipe end first, and then connect the pipes together by rivets or bolts, welding is to directly weld the pipes together. The threaded connection method requires rotating the pipe when connecting or disassembling, which is not only cumbersome but also has low working efficiency. However, if the flange connection is used, the flange joint needs to be fixed on the pipe in advance. Therefore, there is also the problem of cumbersome and inconvenient operation. , and it is also very unsuitable for pipe laying operations that require on-site determination of the length of the operating pipeline. However, it is not only very inconvenient to carry out welding operations at the pipeline connection site by means of welding connection, but also the pipelines connected by welding are difficult to repair and disassemble. It is also very inconvenient. In order to realize the pipe connection operation conveniently, people have adopted a kind of installation groove formed on the end of the pipe at present, and a connector with a protrusion is adopted. The cooperation of the grooves connects adjacent pipes together, which is not only convenient and quick to install, but also very convenient in maintenance and disassembly. However, the current equipment for processing such grooves is complex in structure, inconvenient to operate, and the diameter range of the processed pipes is relatively narrow, which affects the processing of pipe grooves to a certain extent and affects people's pipeline connection work. Existing techniques generally use manual measurement for the depth measurement of pipe fittings, which not only makes the groove inaccurate, but also has certain risks and greatly increases the labor force.
