Abstract
The utility model provides a flange spot welding fixture of a diffuser of an automobile EGR cooling system and can solve the problems of cumbersome operation, complex structure and high equipment cost of the existing flange spot welding fixtures. The flange spot welding fixture comprises a base plate provided with a locating base and is characterized in that a first flange locating split is fixed at the upper end of the locating base, a diffuser casing locating spindle is arranged at the left end of the locating base, a guide rail is arranged on the left side of the locating base, an air cylinder is fixed on the base plate on the left side of the guide rail through a cushion block, a sliding block is arranged in the guide rail, a second flange locating split is fixed at the upper end of the sliding block, locating molded surfaces are both opened on the first flange locating split and the second flange locating split, and a locating molded surface after piecing together of the first flange locating split and the second flange locating split accords with the outer molded surface of a flange.
Description
Technical field
The utility model relates to the part processing technical field of automobile exhaust gas recirculating system, is specially a kind of flange spot welding fixture (SWFX) of new automobile cooling system for recycled exhaust gas diffuser.
Background technology
A kind of automobile exhaust gas recirculated cooling system diffuser; Its structure is seen Fig. 1; Diffuser housing 13 is being connected through the TIG weldering with flange 14; For size and the welding fastness that guarantees that diffuser housing 13 and flange 14TIG weld, before welding, through the form of spot welding the diffuser housing 13 and the preliminary of inner hole wall of flange 14 are fixed earlier, 15 is flange spot welding position among Fig. 1; And then the TIG that carries out whole fillet welds; Because this diffuser has higher installation accuracy requirement, its must guarantee plane on the flange to the circular cavity distance of shaft centers of diffuser housing from meeting design requirement, its structure of flange spot welding fixture (SWFX) of employing is seen Fig. 2 at present; It is through flange positioning boss 16 and flange clamping device 17, diffuser shell positioning clamping device 18 with diffuser shell and flange from vertical and horizontal four direction positioning and fixing on base plate 19; And the diffuser end face of flange is positioned the base plate face, after it need turn over turnback with base plate through rotary cylinder 20, welding gun can stretch into flange spot welding position from the bellmouth on the base plate 21 and carry out the spot welding operation, its complex operation; And flange clamping device and diffuser shell positioning clamping device comprise a pair of cylinder 22 and 23 respectively, its complex structure, equipment cost height.
Summary of the invention
To the problems referred to above, the utility model provides a kind of flange spot welding fixture (SWFX) of new automobile cooling system for recycled exhaust gas diffuser, and it can solve the high problem of complex operation, complex structure, equipment cost that existing flange spot welding fixture (SWFX) exists.
Its technical scheme is such; It comprises base plate, on the said base plate positioning pedestal is installed, and it is characterized in that: said positioning pedestal upper end is fixed with flange location piece one, left end is equipped with diffuser shell positioning core axle; Said positioning pedestal left side is equipped with guide rail; Be fixed with cylinder through cushion block on the said guide rail left-side bottom, in the said guide rail slide block be installed, said upper end of slide block is fixed with flange location piece two; Said flange location piece one and flange location piece two all have a location profile, location profile and flange outer mold surface after said flange location piece one and piece two amalgamations of flange location are agreed with.
It is further characterized in that: the right side of said positioning pedestal is equipped with little cylinder, and the cylinder guide rod external part of said little cylinder holds out against said positioning pedestal through coupling head.
Compare with existing flange spot welding fixture (SWFX) structure; The beneficial effect of the utility model is: it is placed on the positioning core axle simultaneously upwards location of end face of flange with the diffuser shell; Thereby welding gun can directly carry out flange spot welding operation and need not use rotary cylinder with the whole inversion of base plate, has simplified spot welding job step; In addition; Cylinder is when the promotion slide block moves; Flange on slide block location piece two agrees with flange location piece one on the positioning pedestal flange is positioned; Slide body is carried out clamping and positioning with positioning core axle to the diffuser shell simultaneously, and it has been simplified whole locating clip locking structure, has reduced the use of cylinder, has reduced equipment cost.
