The utility model has the advantage that the shielded gas can be more uniformly jetted to a weld joint, can comprehensively protect the weld joint to guarantee the welding quality.
Description
Technical field
The utility model relates to a kind of connector of welding gun, particularly a kind of connector that is used for the TIG welding gun.
Background technology
TIG weldering, i.e. inert gas tungsten electrode protection weldering mainly is to be used to weld thicker stainless steel and also to be used for welding than the heavv section root pass, and main weld adopts built-up welding, and the tungsten electrode in the welding torch is as negative pole, and inert gas is generally argon gas.Inert gas is sent into by welding torch, forms shielding around electric arc and on the welding pool.The protective gas of the connector of existing TIG welding gun is to spray from the pore that is press-fitted assembly; and then be sprayed onto around the tungsten electrode, the inert gas skewness, therefore; the protection of protective gas butt welded seam when being ejected into around the electrode is bad, influences the quality of weld seam.
Summary of the invention
The purpose of this utility model is to spray protective gas around the electrode time from connector at the existing TIG welding gun described in the background technology; the skewness of protective gas; the protection of butt welded seam is bad, influences weldquality easily, and a kind of connection of the TIG of being used for welding gun is provided.
The realization the technical solution of the utility model is as follows:
A kind of connector that is used for the TIG welding gun; it comprises shell and is press-fitted assembly; describedly be press-fitted the conical section that assembly comprises cylindric section of right-hand member and left end; described cylindric section right-hand member is the protective gas incoming end; the tungsten electrode interface that described conical section left end is a swallow-tail form; described cylindric section is sealed and matched with the shell right-hand member; described outer casing inner wall is provided with first step and second step; be provided with the protruding circle in location at cylindric section outer wall; the position of this centring ring is corresponding with first step; cylindric section is provided with several pores; it is arranged at the left end of positioning convex; the conical section outer wall is provided with the 3rd step, and the position of the 3rd step is corresponding with second step, is provided with the several layers silk screen at the 3rd step and second step place; conical section is provided with the 4th step; it is arranged at the 3rd step left end, and the 4th step is provided with trim ring, and its size is higher than the 3rd step.
The tapering of described conical section is 50 °～70 °.
Described silk screen is 100 purpose silk screens.
Described silk screen is 200 purpose silk screens.
The beneficial effects of the utility model are because be provided with the multilayer air sifter in the TIG welding gun connector of the present utility model; therefore can carry out homogenising to the air-flow of protective gas handles; make from connector to be press-fitted the protective gas that component internal enters into around the enclosure tungsten electrode more even; more even when making protective gas be ejected on the weld seam; can comprehensively protect by butt welded seam, guarantee its quality.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model;
Among the figure, 1 is shell, and 2 for being press-fitted assembly, and 3 is cylindric section, and 4 is conical section; 5 is the protective gas incoming end, and 6 is the tungsten electrode interface, and 7 is first step, and 8 is second step, and 9 is the 3rd step; 10 is the 4th step, and 11 are the protruding circle in location, and 12 is silk screen, and 13 is trim ring, and 14 is pore.
The specific embodiment
With reference to a kind of connector that is used for the TIG welding gun shown in Figure 1; it comprises shell 1 and is press-fitted assembly 2; describedly be press-fitted cylindric section 3 and the conical section 4 of left end that assembly 2 comprises right-hand member; described cylindric section 3 right-hand member is protective gas incoming end 5; described conical section 4 left ends are the tungsten electrode interface 6 of swallow-tail form; the tapering of conical section 4 is 50 °～70 °; described cylindric section 3 is sealed and matched with shell 1 right-hand member; described shell 1 inwall is provided with first step 7 and second step 8; be provided with the protruding circle 11 in location at cylindric section 3 outer wall; the position of this centring ring is corresponding with first step 7; be provided with several pores 14 for cylindric section 3; it is arranged at the left end of positioning convex; conical section 4 outer walls are provided with the 3rd step 9; the position of the 3rd step 9 is corresponding with second step 8; be provided with several layers silk screen 12 at the 3rd step 9 with second step 8 places; these silk screens 12 are the different silk screen of density 12; its density is that 80 orders are between 250 orders; conical section 4 is provided with the 4th step 10; it is arranged at the 3rd step 9 left ends; the 4th step 10 is provided with trim ring 13, and this trim ring 13 is the brass trim ring, and its size is higher than the 3rd step 9.Cylindric section 3 right-hand member with shell 1 that is press-fitted assembly 2 is sealed and matched; prevent that protective gas from leaking; being press-fitted assembly 2 by first step 7 and 11 pairs on the protruding circle in location positions; simultaneously; locating protruding circle 11 is adjacent to first step 7; can also strengthen the air-tightness of connector, prevent that further protective gas from leaking.Silk screen 12 is arranged at second step 8 and the 3rd step 9 places, and trim ring 13 is arranged on the 4th step 10, and the size of trim ring 13 is higher than the 3rd step 9, is undertaken spacing by second step 8, the 3rd step 9 and 13 pairs of silk screens of trim ring 12.Tungsten electrode is arranged in the through hole at tungsten electrode interface 6 places.
During the work of TIG welding gun; protective gas enters into connector inside from the cylindric section 3 right-hand member protective gas incoming end 5 that is press-fitted assembly 2 of connector; pore 14 on cylindric section 3 sprays, and enters into shell 1 inside, before around the arrival tungsten electrode; will be through the silk screen 12 of multilayer; by the effect of silk screen 12, make the distribution of protective gas more even, can be sprayed onto uniformly weld seam around; it is protected, guarantee the quality of weld seam.Protective gas generally adopts inert gas, because the inert gas chemical property is stable, not with mother metal generation chemical reaction, thereby cuts off weld seam and air with inert gas, and butt welded seam is protected.
