AI Technical Summary

Technical Problem

Traditional thin-walled pipe fittings are clamped by external curved plates, which can easily lead to extrusion and deformation of pipe fittings and reduce processing accuracy.

Method used

A thin-walled pipe fitting processing tool is designed, using two pipe fitting fixing mechanisms that slide on the center rod to fix them from the inside of the pipe fitting to avoid extrusion deformation caused by external clamping. The fixing mechanism includes sleeves, ring plates, telescopic columns, rubber blocks, adjusting rings and connecting rods, which can adapt to pipe fittings of different lengths.

Benefits of technology

By fixing the inner side, the stability and machining accuracy of the pipe fittings are improved, extrusion deformation caused by external clamping is avoided, and it can be adapted to pipe fittings of different lengths.

Abstract

The utility model discloses a thin-wall pipe fitting machining tool which comprises a center rod, two symmetrically-arranged pipe fitting fixing mechanisms are arranged on the center rod in a sliding mode, each pipe fitting fixing mechanism comprises a sleeve arranged on the center rod in a sliding and sleeving mode, and an annular plate is fixedly arranged at the end, close to the center of the center rod, of each sleeve. A plurality of telescopic columns are slidably arranged on the outer side face of the annular plate, rubber blocks are fixedly arranged at the outer ends of the telescopic columns, adjusting rings are in threaded connection with the ends, away from the annular plate, of the sleeves, movable rings are rotatably arranged at the ends, close to the annular plate, of the adjusting rings, and connecting rods are hinged between the movable rings and the telescopic columns. The two pipe fitting fixing mechanisms arranged on the center rod in a sliding mode are adopted to fix the pipe fitting from the inner side of the pipe fitting, the fixing effect is improved, meanwhile, the problem that the pipe fitting is easily flattened due to fixing from the outer side can be avoided, the two pipe fitting fixing mechanisms can freely slide on the center rod, and therefore the distance between the two pipe fitting fixing mechanisms is adjusted, and the pipe fitting fixing effect is improved. And the device is suitable for pipe fittings with different lengths.
