Description
Technical field
The utility model relates to thin cylinder girth welding field, relates in particular to the thin cylinder girth welding field in the vehicle exhaust after-treatment device, specifically a kind of simple and easy circumferential weld profiling welding device.
Background technology
Some product can relate to the welding of thin cylinder circumferential weld in the industrial production, and for example the connection between each section of SCR converter cylindrical shell is exactly the exemplary of thin cylinder girth welding.1.5 or 2 millimeters thick corrosion resistant plates are rolled into tubular, elder generation's weldering longitudinal joint, back weld-ring seam.Because local uneven heating, weld longitudinal joint after, cylindrical shell radial contour one-tenth " peach shape " brings difficulty to the automatic soldering technique of follow-up circumferential weld.In actual production, to carry out full circle technology usually after the longitudinal seam welding, but the problem that indivedual cylindrical shell still cannot not exist roundly.In order to guarantee the welding quality of circumferential weld, the utility model provides a kind of simple and reliable circumferential weld profiling welding device.Compare with existing circumferential weld profiling equipment, this apparatus structure is simple, and low cost of manufacture is easy to operate.Because contour wheel and welding torch action are synchronously, and can lean on very closely mutually, so the profiling effect is fine, the product that welds out can satisfy the requirement of client's butt welded seam intensity and outward appearance.
Summary of the invention
To be solved in the utility model is the problems referred to above that prior art exists, and aims to provide a kind of simple and reliable circumferential weld profiling welding device.This device can be realized the profiling welding of the relatively poor cylindrical shell circumferential weld of circularity, improves strength of welded joint, improves the weld appearance quality.
For addressing the above problem, the utility model is by the following technical solutions: a kind of simple and easy circumferential weld profiling welding device, comprise position adjusting mechanism, contour wheel, the welding torch welding torch, the compression spring, support, the welding torch clamping device, two guide rails, last undersetting, pedestal, slide block and adjustable Connection Block, it is characterized in that described pedestal links to each other with position adjusting mechanism, last undersetting is fixed on the described pedestal, the described undersetting of going up is provided with two through holes, described two guide rails penetrate wherein and are fixing, be installed with compression spring and slide block on the described every guide rail, described support links to each other with described slide block, described contour wheel and adjustable Connection Block are arranged on the described support, described welding torch clamping device links to each other with described adjustable Connection Block, and can drive the through hole axle center of described welding torch on the adjustable Connection Block and rotate to an angle in the plane by contour wheel axis and torch axis.
Simple and easy circumferential weld profiling welding device of the present utility model at first makes to follow an example by the adjustment position adjusting mechanism and takes turns the appropriate location that is on the cylindrical workpiece excircle configuration, and by the compression spring workpiece applied a suitable thrust.Adjust the appropriate location of adjustable Connection Block on support and the angle of welding torch clamping device, so that the nozzle alignment of welding torch is welded the position.The electric arc that ignites also while turning of work piece comes into effect welding.If workpiece circularity is fine, the reduction length of spring just remains unchanged, and the distance in the nozzle of welding torch and workpiece axle center also remains unchanged; When the circularity of workpiece is relatively poor, for example workpiece has carried out longitudinal seam welding before the boxing, then the radial contour of workpiece may present significantly " peach shape ", when contour wheel walks to the longitudinal joint zone, the distance in contour wheel axle center and workpiece axle center increases, make the nozzle of welding torch rigidly connected also increase, thereby torch neck and workpiece splash metal plug nozzle or generation scratching and influence welding quality when having avoided TIG tungsten electrode contact workpiece when melting welding to cause short circuit or MIG/MAG weldering apart from too closely making with the distance in workpiece axle center with it.Spend longitudinal joint when zone when contour wheel is capable, the reduction length of spring reduces, contour wheel still keeps tight the contact with the excircle configuration of workpiece, and this makes the nozzle of welding torch and the distance in welded piece axle center also reduce, and the nozzle of welding torch remains suitable distance with quilt weldering position.Therefore, under the situation of cylindrical workpieces circularity difference, this profiling welding device also can guarantee the quality of girth welding.
Simple and easy circumferential weld profiling welding device of the present utility model, it has simple in structure, low cost of manufacture, the characteristics easy to operate, that the profiling welding effect is good realize the profiling welding of the relatively poor cylindrical shell circumferential weld of circularity, improve strength of welded joint, improve the purpose of weld appearance quality.
As further improvement of the utility model, described contour wheel is fixed on the described support by following modularity: set gradually rear axle housing, rolling bearing and front shaft sleeve on the axle of described contour wheel, and be fixed on the described support by nut.Described contour wheel is fixed by screw and described rolling bearing.
Further improve as of the present utility model, described guide rail also is set with the cushion pad of avoiding described slide block and below bearing generation hard collision again.
Further improve as of the present utility model again, have slotted hole on the described support, described adjustable Connection Block can be regulated its horizontal level on described support by described slotted hole.
Further improve as of the present utility model, also have larger-size slotted hole on the described support, its major axis is vertical with the through hole axle center on the adjustable Connection Block with the plane that the contour wheel axis is formed, welding torch can pass described slotted hole, and the through hole axle center on described adjustable Connection Block rotates.
