Description

The supporting mechanism of the automatic pipe cutting machine

technical field

The utility model relates to the technical field of pipe cutting machines, in particular to a material supporting mechanism of an automatic pipe cutting machine.

Background technique

During the processing of pipe fittings, it is often necessary to cut the pipe fittings first to facilitate the subsequent welding, polishing, grinding and other processes. However, the cutting process of pipe fittings in the prior art often relies on pipe cutters for cutting, and its working process is simple. It is said that the end of the pipe fitting is manually inserted into the machine tool, the controller on the machine tool drives the chuck to clamp the pipe fitting through the driver, and then the driving motor of the machine tool drives the pipe fitting to rotate, and finally cuts the pipe fitting through the radially fed cutter to complete the pipe fitting of cropping. In the process of processing, a guide frame is generally used to lift the pipe, that is, the pipe is lifted by several sets of guide wheels. The axes of the guide wheels are parallel to the axis of the pipe, so that when the pipe rotates, the guide wheels rotate synchronously.

However, in the above-mentioned guide frame used on the pipe cutting machine in the prior art, when the pipe is fed in the axial direction, the edge of the guide wheel will cause scratches on the pipe. Even if the edge of the guide wheel is rounded, it is easy to cause scratches on the surface of the pipe during the continuous sliding friction process. At the same time, with long-term use, after the surface of the guide wheel is rusted, the surface of the pipe will be scratched during the sliding process. will be more serious.

The technical solution adopted by the utility model is: to provide a material supporting mechanism of an automatic pipe cutting machine, which includes a frame, on which there are translation guide wheels, rotation guide wheels, and driving translation guide wheels or rotation guide wheels The driving mechanism on the outer wall of the pipe fitting, when the pipe moves axially, the translation guide wheel fits and rolls against the outer wall of the pipe, and when the pipe rotates around its own axis, the rotating guide wheel fits and rolls against the outer wall of the pipe.

The drive mechanism includes a first support rod, a second support rod, a connecting rod, and a conversion cylinder that drives the connecting rod to translate in the axial direction. The upper end of the rod is rotated and matched, the middle parts of the first support rod and the second support rod are respectively hinged with the frame, the bottom of the first support rod and the bottom of the second support rod are respectively provided with bar-shaped grooves, corresponding to each The position of the bar-shaped groove is provided with a protruding shaft matched with the bar-shaped groove, and the extension line of the first support bar along the length direction intersects the extension line of the adjacent second support bar along the length direction.

There are three translation guide wheels and three rotation guide wheels, and all translation guide wheels and rotation guide wheels are arranged alternately.

The translation guide wheel is a drum-shaped structure with a middle diameter smaller than that at both ends.

The rotating guide wheel is composed of two sub-rollers, and the two sub-rollers are respectively rotated and matched with one end of the second support rod through the extension plate. Both sides of the straight plane.

After adopting the above structure, the material supporting mechanism of the automatic pipe cutting machine of the present invention has the following advantages compared with the prior art: the rotating guide wheel of the pipe fitting fits the pipe fitting during the rotation process, and the translation guide wheel and the pipe fitting move along the axial direction. The fittings fit snugly so that the rolling friction between the fittings and the guide wheels is always maintained so there is no chance of scratching the fittings surface.
