Technical field
The present invention relates to the part processing technical field of automobile exhaust gas recirculating system, be specially the support weld jig of new automobile cooling system for recycled exhaust gas diffuser.
Background technology
A kind of automobile exhaust gas recirculated cooling system diffuser; See Fig. 1; It comprises diffuser housing 18, and the roundlet mouth end of housing 18 is fixed with adpting flange 19, and surface of shell has been welded to connect a support 20; Because the use installation accuracy of this diffuser is high; Therefore when carrying out the support welding, at first adopt and utilize electric resistance welding that support and housing are carried out Primary Location, and then support is fixing with the upper casing welding, thereby can its electric resistance welding carry out the first precision of welding for entire bracket of locating with support and upper casing and meet the demands particularly important through the mode of soldering.Among Fig. 1,21 is the resistance welded position of diffuser shell and support.The support weld jig that adopts at present; Its structure is seen Fig. 2; Diffuser shell 18 was positioned on the workpiece locating piece when it used; The flange fastening screw 28 of flange end positioner and roundlet mouth fastening screw 29 be diffuser osculum end location, support be positioned over support guide pad 24 and through fastening screw 25 and spacing latch 26 position, spacing, be fixed in the welding position by clamp device 27 energetically again; Its shortcoming is: the positioning and clamping of diffuser shell and support all through manual fastening screw, energetically the folder operate; Make the positioning and clamping precision of diffuser shell and support be vulnerable to the influence of manual operation, simultaneously, its clamping step is loaded down with trivial details, clamping efficient is low.Among Fig. 2,30 is base plate, and 31 is the fastening screw seat, and 32 is spacing plug housing.
Summary of the invention
To the problems referred to above; The invention provides the support weld jig of new automobile cooling system for recycled exhaust gas diffuser; Its positioning and clamping precision that can solve the existing support weld jig existence of employing is subject to the manual operation influence, and the while is clamping program, raising clamping efficient simply.
Its technical scheme is such; It comprises base plate; Diffuser shell positioning and clamping device and support positioning and clamping device are installed on the said base plate, and said diffuser shell positioning and clamping device comprises workpiece locating piece and flange end positioner, it is characterized in that: said support positioning and clamping device comprises support locating piece and support compact heap; Said support locating piece is installed on said base plate; Said support compact heap connects the support clamping cylinder through toggle, and said flange end positioner comprises flange locating piece and roundlet mouth location mandril, said flange locating piece and roundlet mouth location mandril adpting flange end positioning cylinder.
It is further characterized in that: said support clamping cylinder is installed on said base plate through fixed mount; Said toggle comprises crank and connecting rod; Said support clamping cylinder output is connected with said crank, and said crank is connected with said support compact heap through said connecting rod; Said flange end positioning cylinder is installed on guide pad through cushion block, and said guide pad is installed on said base plate, and said flange locating piece is connected with said flange end positioning cylinder output with roundlet mouth location mandril.
It further is characterised in that: it also comprises diffuser shell compact heap, and said diffuser shell compact heap is installed on said base plate through rotary cylinder.
Compare with existing support welding support structure; Beneficial effect of the present invention is: its support positioning and clamping device and flange end positioner are realized the location of diffuser shell and support is compressed by air cylinder driven; And diffuser shell compact heap also has rotary cylinder to drive; Thereby guaranteed the location clamping accuracy of diffuser shell, support to adopt the air cylinder driven effectively to improve clamping workpiece efficient, thereby improve the welding efficiency of diffuser shell and support simultaneously.
