Embodiment Construction

[0011] Next, the specific structure of the welded pipe center floating adjustment clamping device of the present invention will be described in detail according to the accompanying drawings. Such as figure 1 As shown, the welded pipe center floating adjustment clamping device includes at least two (in this embodiment figure 1 Shown as four, but also three or more according to the length of the welded pipe) according to the diameter of the welded pipe 13, the center of which can be adjusted and the welded pipe is clamped. A welded pipe diameter adjustment clamping mechanism 50, and a The welded pipe diameter adjustment clamping mechanism 50 can be manually adjusted according to the length of the welded pipe 13 to reduce the welded pipe length manual adjustment mechanism 60 that shakes at the end of the welded pipe.

[0012] And the welded pipe diameter adjustment clamping mechanism 50 has: the height adjustment unit 40 of the upper support roller, which adjusts and supports th...

Abstract

The invention relates to a floating regulating and clamping device for the center of a welding tube, which comprises more than two welding tube diameter regulating and clamping mechanisms (50, 50) and a welding tube length manual regulating and clamping mechanism (60) with the welding tube diameter regulating and clamping mechanisms. The invention has the advantages of simple structure, easy operation, stability, reliability, higher regulating accuracy and efficiency, and long service life.

Description

technical field [0001] The invention relates to the field of drill pipe manufacture, in particular to a welded pipe center floating adjustment clamping device for friction welding and centering clamping of the welded pipe. Background technique [0002] In drill pipe manufacturing operations, friction welding is a key process. Because the welded pipe is long and has many specifications with different diameters and lengths, it is required to be coaxial without shaking during welding. The traditional clamping device adopts manual adjustment for the adjustment of different welded pipe diameters or the adjustment mechanism has low strength and poor rigidity, and has no adjustment function for the length of the welded pipe. The original floating clamping device of the welding machine is difficult to center, clamp and adjust, and it is laborious and time-consuming , low service life. Contents of the invention [0003] In order to solve the above problems, the present invention p...
