And when being welded to connect bonnet and outer tube, the general mode of manual welding that adopts is carried out at present, namely welding gun is adopted the bonnet of matched together and outer tube to be directly welded to connect, when welding, because directly welding equipped bonnet and outer tube, positioning tool is not set, outer tube and bonnet locating effect are not very desirable, affect the accuracy of welding position to a certain extent, and the outer tube of no-fix and bonnet are when welding, and operate cumbersome.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of good positioning effect, and the bent tube type tailpipe welding tooling of welding operation precisely, and is convenient in energy effective guarantee outer tube and bonnet welding position.
For solving the problems of the technologies described above, technical scheme provided by the invention is: comprise bearing, be positioned at cylinder above tail pipe by support installing, be arranged on bearing and be provided with die cavity to locate the positioning module of bent tube type tailpipe on bearing, described cylinder piston rod free end is connected with depression bar downwards, and described depression bar lower end is pressed in tail pipe top.
Described depression bar lower end and tail pipe top are coaxially set, and when tail pipe top is pressed in depression bar lower end, have ensured the precision of bonnet and outer tube welding position further.
Described depression bar, cylinder piston rod are also coaxially set with tail pipe top, make cylinder piston rod linearly force in depression bar, depression bar and linearly force in tail pipe top, and linearly biasing effect is best, also can ensure the precision of bonnet and outer tube welding position.
The briquetting being arranged on depression bar lower end is also provided with between described depression bar lower end and tail pipe top, the bottom of described briquetting is for ease of being pressed into the taper press-in end in tail pipe top, the top of described briquetting is the cylindrical positive stop end that diameter is greater than tail pipe internal diameter, the setting of the briquetting of this planform can make depression bar firmly press tail pipe top further, the taper press-in end of briquetting smooth and easyly can snap onto tail pipe inside, and the cylindrical positive stop end on top can spacingly make whole briquetting be pressed on tail pipe top at tail pipe top.
Described bearing comprises upper mounting plate, infrabasal plate and the support column for connecting upper mounting plate and infrabasal plate, described support installing is on upper mounting plate, the bottom of described support is parallel with outer tube, the top of this support is parallel with tail pipe top, described cylinder is arranged on the top of support by installing connecting plate, described positioning module is directly installed on upper mounting plate, the bearing of this planform is on the one hand because the setting of support column makes to have certain height space between upper mounting plate and infrabasal plate, be convenient to the carrying to whole bearing like this, after cylinder is arranged on upper mounting plate by support and installation connecting plate on the other hand, cylinder can be facilitated indirectly to do in and tail pipe top.
Bent tube type tailpipe welding tooling of the present invention, by the setting of positioning module, utilize cylinder downward moulded rod above tail pipe, depression bar forces its lower end press tail pipe top and make whole bent tube type tailpipe realize firm Set and Positioning, tailpipe after such Set and Positioning just can move on automatic welding table with bent tube type tailpipe welding tooling and carry out automatic welding, when welding, whole outer tube, bonnet and tail pipe are by firm Set and Positioning, there will not be loosening, shifting phenomena, add the setting of positioning module, effective guarantee to be welded to connect the precision of position between outer tube and bonnet, such outer tube and bonnet welding position are then very accurate, and in welding process, bent tube type tailpipe is by firm Set and Positioning, facilitate the welding of welding machine.
