Abstract
The utility model discloses a pipe orifice pressure convergence limit structure inserting into an evaporator pipe for welding, which comprises the evaporator pipe and is characterized in that the pipe orifice pressure convergence part of the inserting end of each evaporator pipe is provided with a circle of arc-shaped protruding limited block; and the external diameter of the limited block is not more than that of the inserted welded pipe. The limit structure uses a circle of limited blocks to conduct limiting and welding on the inserted welded pipe, thus not only having uniform inserting depth, but also being capable of effectively improving the welding quality and speed.
Description
Technical field:
The utility model relates to the fixing of welding work pieces or location, particularly a kind ofly inserts the poly-position limiting structure of pressing of the plug-in type pipeline welding mouth of pipe that size is accurate, quality good, work efficiency is high.
Background technology:
Evaporator pipeline be inserted into pipeline when welding, need control effectively to insertion depth, adopt artificial line location at present, this mode is because insertion depth can not guarantee unifiedly, so not only influence welding quality, and welding efficiency is low.
Summary of the invention:
The purpose of this utility model provides the poly-position limiting structure of pressing of the mouth of pipe of the insertion evaporator pipeline welding that a kind of insertion depth is unified, welding quality good, efficient is high.
Technical solution of the present utility model is finished as follows, it includes evaporator pipeline, it is characterized in that: be provided with the limited block that a circle arc has been given prominence in the poly-splenium position of the insertion end mouth of pipe of each evaporator pipeline, the external diameter of limited block≤the be inserted into external diameter of welded tube.The utility model carries out spacing welding with a circle limited block to being inserted into welded tube, and not only insertion depth is unified, and can improve welding quality and speed effectively.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
The utility model is the limited block 2 that is provided with a circle arc-shaped protrusions in the poly-splenium position of insertion end 3 mouths of pipe of evaporator pipeline 1, and the external diameter of limited block is equal to or less than the external diameter that is inserted into welded tube 4.This structure, the degree of depth of inserting when not only at every turn welding is unified fixing, and can improve the quality and the speed of welding effectively.
