Abstract

The invention relates to an open three-point centering mechanism. A rotating shaft is arranged in a connecting support in a rotating manner, the rotating shaft is fixed with a rotating support, the rotating support is fixed with an adhesion wheel support, a first rotating wheel is erected on a first mounting plate, a second rotating wheel is erected on a second mounting plate, a third rotating wheel is erected on a third mounting plate, the first mounting plate is hinged with a first connecting rod, the second mounting plate is hinged with a second connecting rod, the other end part of the first connecting rod and the other end part of the second connecting rod are all hinged on a third mounting shaft, and the adhesion wheel support is provided with a lifting driving component of the third mounting shaft. In the invention, one hydraulic cylinder is used for driving three adhesion centering wheels to move, circle centers of the three centering wheels are effectively ensured to be always located on concentric circles which have the circle centers on the same point and have different diameters, and centering function on pipes with different diameters can be realized.

Description

technical field [0001] The invention relates to an equipment component of a numerically controlled spinning machine for ultra-long thin-walled pipe fittings, in particular to an open-type three-point centering mechanism. Background technique [0002] In the process of spinning super-long thin-walled pipe fittings to form tapered pipes or special-shaped pipes, at a place far away from the supporting point of the pipe fittings, due to the lack of rigidity of the thin-walled pipe fittings themselves, when the pipe fittings are rotating at high speed, the pipe fittings will produce very large Vibration, and excessive vibration will cause the interruption of the spinning process of ultra-long thin-walled pipe fittings, and the entire processing process cannot be completed. The open three-point centering mechanism is exactly the mechanism developed to solve this problem. [0003] The current centering mechanisms for pipe fittings or cones or special-shaped parts all realize auxil...
