Tube external circle repairing device

Abstract

The invention discloses a tube external circle repairing device. A tool rest and a power mechanism are arranged at the left end and the right end of a small bottom plate; a main shaft of the tool rest is coaxial with the power mechanism; the small bottom plate is arranged on a small bearing plate which is a feeding mechanism; the main shaft of the tool rest is parallel to the feeding direction ofthe small bearing plate; a tube clamping frame and the small bearing plate are arranged on a large bottom plate; the main shaft of the tool rest is coaxial with a cambered positioning surface of a tube clamping frame mounting pedestal of the tube clamping frame; a corresponding tool setting strip is selected to adjust the position of a tool on the tool rest according to the size of a machined external circle; after the tool is arranged, the tool setting strip is taken out of a central cavity of the main shaft; a tube to be machined is fixed on the clamping frame mounting pedestal; one end of a spindle has an outer hexagonal shape, and the other end of the spindle is a clamping end; after the clamping end of the spindle is matched with the inner side of the tube to be machined, the other end of the spindle is inserted into the central cavity of the main shaft; and during machining, the spindle is in a static state, the tool rest is driven by the power mechanism to rotate relative to the spindle, and the small bearing plate is linearly fed so as to finish the machining.

Description

technical field [0001] The invention relates to a repairing device for the outer circle of a pipe, which is particularly suitable for processing the inner and outer circles and end faces of complicated pipes with a distance of 40 mm from the end face. Background technique [0002] Pipes are an essential and important part of various aviation and spacecraft products and refrigeration equipment. With the increase in the number of model tasks, the production tasks involving pipes have doubled. The types, specifications, and trends of pipes are diversified, including Ω-type pipes , Φ-shaped tube, square heat pipe, etc., with a specification of φ6-30, and its direction is mostly three-dimensional space layout. Conduit profile pipe-pipe butt welding needs to round the inner pipe opening 30mm from the end face of the pipe to meet the welding requirements. If the quality of the weld is unqualified, it is necessary to re-round the cut-off of the unqualified weld to meet the needs of...

Problems solved by technology

[0004] The method of manually filing the outer circle of the pipe is labor-intensive and low in production efficiency. It not only cannot meet the needs of product progress, but also cannot meet the requirements of welding for the accuracy of the outer circle of the pipe and the accuracy of the wall thickness, which seriously restricts the reliability and consistency of pipe welding. , making it a bottleneck in the development and production of pipe products, there is an urgent need for a device that is convenient and can quickly and accurately process the outer circle of pipes
