Abstract
The utility model provides a butt welding tool of a connecting pipe and a flange pipe, which can ensure the accurate butt position of the flange pipe and the connecting pipe and is easy to control. The butt welding tool of the connecting pipe and the flange pipe comprises three parallel clamping shafts which are uniformly distributed in the same circumferential direction and are used for stretching into the connecting pipe and the flange pipe, and the clamping shafts are connected with a radial synchronized driving mechanism which drives the clamping shafts to synchronously move along the radial direction of the radial synchronized driving mechanism.
Description
Technical field
Present technique relates to takes over and flanged pipe butt welding frock, relates in particular to the small takeover (frock of DN≤50mm) and the butt welding of hubbed flange pipe.
Background technology
In the pressure vessel manufacture process; (DN≤50mm) and flanged pipe (pipeline that has flange) are when especially the hubbed flange pipe docks small takeover; The bad control of counterpart unfitness of butt joint and counterpart gap causes counterpart place slope type to guarantee, influences welding quality and product appearance.
Summary of the invention
The purpose of present technique provides a kind of docking location accurate and the adapter and flanged pipe butt welding frock control easily that can guarantee flanged pipe and adapter.
This adapter and flanged pipe butt welding frock comprise that being distributed on three parallel being used to that make progress in same week stretches into the axis in adapter and the flanged pipe, and axis links to each other with its radially synchronization-moving radially synchronous drive mechanism of drive.
Above-mentioned adapter and flanged pipe butt welding frock, said axis is a circular shaft.
The beneficial effect of present technique: during use, three axis stretch into take over flanged pipe in, make three axis radially outwards move synchronously through synchronous drive mechanism radially then, be positioned at adapter and flanged pipe simultaneously on three axis.Like this; Position through the endoporus of three axis with adapter and flanged pipe; And also can change as required and take over and the relative position of flanged pipe, so this butt welding frock can guarantee that the docking location of flanged pipe and adapter is adjusted easily at axial direction; And docking location is accurate, has guaranteed welding quality.
Description of drawings
Fig. 1 takes over and the sketch map of flanged pipe butt welding frock in user mode.
Fig. 2 is the side view (right view of Fig. 1) of adapter, flanged pipe, axis etc.
The specific embodiment
Referring to Fig. 1, adapter and flanged pipe butt welding frock shown in 2, comprise being distributed on the three parallel axis (circular shaft) 1 that make progress in same week that the left end of axis links to each other with the radially synchronization-moving radially synchronous drive mechanism 2 of drive axis.Axis stretches into the endoporus of small takeover 3 and hubbed flange pipe 4.Radially synchronous drive mechanism 2 is arranged on the support 5.
Adjustable the pawl (axis) that this frock is stretched in adopting utilizes 3 pawls flexible simultaneously, and adjustment counterpart place small takeover is concordant with the internal orifice of hubbed flange pipe, reaches the purpose that reduces whole groove counterpart unfitness of butt joint.This frock making is simple and easy, and dependable performance can effectively guarantee the groove quality that small takeover docks with hubbed flange.
Radially synchronous drive mechanism belongs to prior art, just belongs to a kind of radially synchronous drive mechanism like the scroll chuck of lathe.
Claims (2)
1. take over and flanged pipe butt welding frock, it is characterized in that: it comprises that being distributed on three parallel being used to that make progress in same week stretches into the axis in adapter and the flanged pipe, and axis links to each other with its radially synchronization-moving radially synchronous drive mechanism of drive.
2. adapter as claimed in claim 1 and flanged pipe butt welding frock is characterized in that: said axis is a circular shaft.
