Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a groove inner wall processing tool. Background Art

[0002] Grooved pipe fittings are a new type of steel pipe connection fittings, also called clamp connections. Grooved pipe fittings have unique flexibility, which makes the pipeline resistant to vibration, shrinkage and expansion. Compared with welding and flange connections, the stability of the pipeline system is increased and it is more suitable for temperature changes, thereby protecting the pipeline and reducing the damage to the structural parts caused by pipeline stress. Since the grooved pipe fittings are easy to connect and the required operating space is smaller, it brings many convenient conditions for future maintenance and reduces maintenance time and maintenance costs. Before groove processing of pipe fittings, it is necessary to fix the pipe fittings to be processed first, and then use machining to mill the grooves.

[0003] However, when fixing the pipe fittings during the processing of the inner wall of the groove, the traditional three-jaw chuck only fixes the pipe fittings from a single direction. When processing longer pipe fittings, both ends cannot be fixed at the same time, which causes the pipe fittings to shake during milling, thereby affecting the forming of the inner wall of the groove, easily resulting in defective products, and reducing work efficiency. For this reason, we propose a groove inner wall processing tooling to solve the above problems. Utility Model Content
