Description

A kind of method of car air-conditioner pipeline pipeline section welding
Technical field
The present invention relates to car air-conditioner manufacturing technology field, specifically, relate to the method for a kind of car air-conditioner pipeline pipeline section welding.
Background technology
Can relate to many parts to be connected with the pipeline between parts in the manufacture of car air-conditioner, and the connected mode of these air-conditioning ducts also mainly adopts the mode of pipeline section welding at present.When pipeline section welds, need accurate welding tooling to control the fastness of the accuracy of air-conditioning duct soldering angle, the sealing of welding and welding.Because the sealing of air-conditioning duct is particularly important in operation of air conditioner.The welding method of existing air-conditioning duct comes with some shortcomings, and main manifestations is: during the longer and air-conditioning duct that solder joint is more of (1) processing, welding tooling more complicated, and difficult processing, can not very put in place to the control of soldering angle.(2) air-conditioning duct is when welding, except welding tooling, whether insertion depth when weldment connects puts in place and mainly to judge by Welder, and Welder judges by subjective operating experience, these process right and wrong are controlled, be difficult to ensure weldment quality (see Fig. 1: the mouth of pipe 01 is invisible at pressing plate nose end 02 and the contiguity of through hole 03, the mouth of pipe 01 come in and go out through hole 03 weld time, concrete link position will judge by Welder; Again owing to being the mode inserted, gap is comparatively large, can not ensure that welding fluid does not flow into through hole 03 place from pressing plate nose end 02 completely, so stifled phenomenon is easily welded at through hole 03 place, connection precision and welding quality are difficult to be guaranteed).(3) existence of the problem that soldering angle controls and link position judges causes ensureing the completely qualified of weldment product, easily occur that connector insertion depth is not in place, cause in welding fluid inflow pipe or on pressing plate or in all the other weldment endoporus, cause the quality problems that weldering is stifled.(4) after the Welding Problems of air-conditioning duct easily causes car air-conditioner to use a period of time, the pad of air-conditioning duct easily produces fatigue and ruptures, and makes car air-conditioner occur leakage phenomenon, affects the use of car air-conditioner.
Summary of the invention
The object of the invention is to the above-mentioned deficiency of customer service, a kind of welding method of car air-conditioner pipeline is provided, it is adopted and is first assembled by helicitic texture by air-conditioning duct, add the controllability of air-conditioning duct, the mode of welding is carried out again when ensureing that weldment connection puts in place, perpendicularity when air-conditioning duct welds can be ensured, the anti-of pad can also be promoted and draw holder intensity, make the welding wire length of penetration of pad and sealing property more reliable, extend the service life of air-conditioning duct, improve the total quality of car air-conditioner, in addition, the input of frock clamp can also be reduced, be conducive to manufacture and the use of car air-conditioner.
For achieving the above object, present invention employs following technical scheme.
A method for car air-conditioner pipeline pipeline section welding, is characterized in that, comprise following steps:
(1) helicitic texture is set on air-conditioning duct
Corresponding helicitic texture is being set as on the mouth of pipe outer wall of syndeton and pressing plate nose end inwall: external screw thread is set on described mouth of pipe outer wall, described pressing plate nose end inwall arranges internal thread;
(2) pipeline section is threaded
The described mouth of pipe is connected with the internal thread on described pressing plate nose end inwall by external screw thread, the described mouth of pipe is threaded with described pressing plate nose end, corrects before the described mouth of pipe and against openings end;
(3) pipeline section welding
With welding tooling, air-conditioning duct (mouth of pipe and pressing plate nose end) is welded.
Further, described air-conditioning duct arranges helicitic texture: external screw thread is set in one end of the syndeton of correspondence, internal thread is set at the other end of the syndeton of correspondence.
Further, described external screw thread should be corresponding with welding position with the processing dimension of described internal thread: namely, and it is exactly the welding position of air-conditioning duct parts that described external screw thread and described internal thread have been tightened.
The good effect of the method for a kind of car air-conditioner pipeline of the present invention pipeline section welding is:
(1) air-conditioning duct is first assembled by helicitic texture by employing, welding again, ensure that perpendicularity when air-conditioning duct welds, improving the anti-of pad and draw holder intensity when ensureing that weldment connects and puts in place.
(2) both added air-conditioning duct pipeline section welding time controllability, also make the welding wire length of penetration of pad and sealing property more reliable.
(3) extend the service life of air-conditioning duct, improve the total quality of car air-conditioner, in addition, the input of frock clamp can also be reduced, be conducive to manufacture and the use of car air-conditioner.
