The invention provides a positioner system. The positioner system comprises a rotating device and a supporting device. The rotating device comprises a support, wherein the support is connected with a rotating arm through a horizontally-arranged first driving shaft, the first end of the rotating arm can rotates around the first driving shaft and connected with a chuck through a second driving shaft, the axis of the second driving shaft is perpendicular to the axis of the first driving shaft, the second driving shaft and the chuck are coaxial, at least three clamping jaws are evenly distributed on the chuck in the circumferential direction and connected with a drive device, the drive device is used for driving the clamping jaws to radially extend along the chuck so as to enable the clamping jaws to clamp the inner wall of one end of a pipe fitting. The supporting device comprises a base, wherein the base is connected with a driven wheel group through a horizontal rotating shaft and used for being in contact with the outer wall of the other end of the pipe fitting so as to support the pipe fitting. The positioner system can decrease coaxiality errors during pipe welding.
Description
technical field [0001] The invention relates to welding auxiliary equipment, in particular to a positioner system. Background technique [0002] The positioner is a special welding auxiliary equipment, which is suitable for the welding position of the rotary work, so as to obtain the ideal processing position and welding speed. [0003] The existing positioner adopts the base support type fixation and external card type rotation mode, which causes the problem of large coaxiality error during pipe welding. Contents of the invention [0004] The invention provides a positioner system to reduce the coaxiality error during pipe welding. [0005] The present invention provides a positioner system, including: [0006] The rotating device includes a support, the support is connected to the rotating arm through a horizontally arranged first driving shaft, the first end of the rotating arm can rotate around the first driving shaft, and the first end of the rotating arm passes thr...
