提案されている。However, in the manual deburring work, not only the working environment is extremely bad due to the generation of noises and vibrations, but also the generation of polishing powder, and not only a great amount of working labor is required, Deburring is incomplete and satisfactory results cannot be obtained even on the finished surface. As means for automating the deburring work, it has been proposed to mount a rotary polishing machine such as a grinder on a robot hand and press the polishing surface against the pipe end surface to polish and deburr by controlling the position of the robot hand.

ないという問題がある。However, when deburring is performed using a robot, although the working environment can be improved and labor can be saved, there are problems in the following points. That is, if the pipe is deformed in an elliptical shape, the radial position of the end face in the rotating state of the pipe, that is, the finishing position changes, so that the robot can cope with such a change in the finishing position. extremely difficult. In order to cope with this problem, it is conceivable to always sense the radial position of the pipe end face and perform feedback control of the polishing surface position of the rotary polishing machine, but for that purpose, advanced sensor control technology is required, and equipment including robots is required. The whole becomes very expensive. It is also conceivable to attach a rotary grinder to the robot hand through an elastic absorption mechanism that absorbs a change in the radial position of the pipe end face with a spring, a cushion, or the like. As a reaction due to the elastic absorption action corresponding to the fluctuation, the position of the polished surface is apt to hunt, and the deburring surface is unnecessarily wavy and the finish quality is not stable.

It is an object of the present invention to provide an apparatus for deburring a pipe end face capable of performing predetermined deburring finish reliably and stably in quality.

The outer peripheral surface is polished, and then, the polishing surface of the rotary polisher is pressed against the pipe end surface corner in a posture inclined with respect to the pipe axis via a polishing angle changing mechanism and a polishing position changing mechanism, and the end surface angle is adjusted. The part can be polished, and the two-step polishing operation can be completely removed without leaving any burrs generated on the end face of the pipe.

バリ取り仕上げを行うことができる。When the radial position of the end face of the pipe fluctuates due to the effect of the pipe itself being deformed into an elliptical shape during polishing, the polishing surface of the rotary polishing machine follows the change. The pressing pressure adjusting mechanism allows to fluctuate in the direction, and the pressing pressure adjusting mechanism maintains a constant pressing pressure of the polishing surface of the rotary polishing machine against the pipe end face, so even if the pipe has an elliptical deformation, A high quality deburring finish can be performed by uniformly polishing over the entire circumference without excessively shaving the local portion of the pipe end face or causing insufficient polishing.

上げを行うことができる。During the deburring and polishing of the outer peripheral surface of the end face 1b of the insertion opening 1B and the deburring of the corner of the end face, the above-described pressing pressure adjusting mechanism 31 works to polish the grinder 28 on the pipe end face 1b. The pressing pressure F of the surface 28a is kept constant, and the end face 1b of the pipe 1b is affected by the elliptical deformation or bending of the pipe 1.
Even if the radial position f changes, the pressing pressure F is always kept constant, so that the polishing is always performed under an appropriate pressing pressure. As a result, even if the pipe 1 is deformed in an elliptical shape or bent in the middle, the entirety of the pipe end face 1b is not cut off unnecessarily or the polishing of the pipe end face 1b is not insufficient. High quality deburring can be performed by polishing uniformly over the circumference.

る。As described above, according to the present invention, the polishing of the rotary polishing machine is held in a posture parallel to the pipe axis, and the polishing surface of the rotary polishing machine is inclined with respect to the pipe axis. The burrs can be completely removed by the two-stage polishing action of polishing in which the posture is maintained. Moreover, even when the radial position of the end face of the pipe fluctuates due to the elliptical deformation or bending of the pipe itself, polishing can be performed while always maintaining the pressing pressure on the polishing surface at an appropriate pressing pressure. It is possible to finish the deburring by uniformly polishing the entire circumference without shaving the end face of the pipe more than necessary or causing insufficient polishing.
