Abstract
The invention relates to a welding fixture for a diffuser bracket of a recycling cooling system of automobile exhaust gas. The welding fixture is used for ensuring the reliable positioning of the diffuser bracket and a diffuser shell during an electric resistance welding process and ensuring the positioning precision. The welding fixture comprises a base plate and is characterized by further comprising a diffuser shell positioning device and a bracket positioning device, wherein the diffuser shell positioning device comprises a workpiece positioning block; an exterior wall of the workpiece positioning block is matched with an inner circular wall of the diffuser shell; the bracket positioning device comprises a bracket guide block and a limiting plug; a positioning plug is arranged on the bracket guide block; and the limiting plug is mounted on the base plate through a plug base.
Description
Technical field
The present invention relates to the part processing technique field of automobile exhaust gas recirculating system, be specially the support welding clamp of automobile exhaust recirculation cooling system diffuser.
Background technology
A kind of automobile exhaust recirculation cooling system diffuser, see Fig. 1, it comprises diffuser housing 1, the little round mouth end of housing 1 is fixed with adpting flange 2, surface of shell has been welded to connect a support 3, because the use installation accuracy of this diffuser is high, therefore first adopt when carrying out support welding and utilize electric resistance welding that support and housing are carried out Primary Location, and then by the mode of soldering, support and upper casing are welded and fixed, thus can support and upper casing to be carried out the just precision of locating for whole support welding by electric resistance welding and meet the demands particularly important by it.Support welding in the past for this kind of diffuser does not have special fixture, and the main manual identified position location that relies on is welded again, and its positioning precision is poor, and working (machining) efficiency is low.In Fig. 1,15 is the electric resistance welding position of diffuser shell and support.
Summary of the invention
For the problems referred to above, the invention provides the support welding clamp of automobile exhaust recirculation cooling system diffuser, reliable location when it can ensure that diffuser support and housing carry out electric resistance welding, ensures positioning precision.
Its technical scheme is such, it comprises base plate, it is characterized in that: it comprises diffuser shell positioner and support frame positioning device, described diffuser shell positioner comprises Workpiece fixing block, described Workpiece fixing block outer mold surface coordinates with described diffuser shell inner headed face, described support frame positioning device comprises support guide pad and limit bolt, and described support guide pad is provided with fastening screw, and described limit bolt is installed on described base plate by plug housing.
It is further characterized in that: described limit bolt to be installed on above described Workpiece fixing block by described plug housing and its setting angle is identical with support installing angle; Described support guide pad is also provided with clamp device energetically; Described diffuser shell positioner also comprises flange end positioner, described flange end positioner comprises flange fastening screw and osculum fastening screw, described flange fastening screw and osculum fastening screw are all installed on fastening screw seat, and described fastening screw seat is fixed on described base plate by cushion block; Described flange fastening screw is vertical with diffuser end face of flange, and described osculum fastening screw is parallel with described flange fastening screw is installed on described fastening screw seat.
Adopt support welding clamp of the present invention, its beneficial effect is: its diffuser shell positioner and support frame positioning device can carry out reliable localization and clamping to the installation requirement according to diffuser shell and support, for diffuser shell and the further brazing operation of support provide reliable Primary Location.
