At the same time, the device adopts a roller-type rolling and joining device, so that the gap between the tailor-welded blanks can be rolled and joined, which can greatly improve the laser welding quality and welding strength of the finished workpiece, and reduce the reject rate. The disadvantage of this device is that The design is complex, the equipment is huge, the mobility is poor, and the cost of use is too high
[0008] The laser tailor welded blank welding fixture designed by C.H.Cheng of the Hong Kong Polytechnic University can meet the laser tailor welded blank welding requirements of his experiment, but the fixture design cannot realize the welding of the curve weld, and its welding heat dissipation is poor, and the tailor welded blank The clamping positioning is also more cumbersome

Embodiment Construction
[0029] The following takes the welding of curved seams as an example, combining figure 1 Describe in detail the details and working conditions of the specific device proposed by the present invention.
[0030] The fixture uses the base 10 as the base, and the steps on the base 10 are used in conjunction with the base height adjustment sheet 11. By changing the thickness of the base height adjustment sheet 11, the height difference of the base steps can be adjusted, and different thicknesses can be achieved when welding curved seams. Combined tailor welded blank welding, such as figure 1 As shown, the left and right pressure plates 3'4' are supported by pads 7, the hexagon socket screws B6 pass through the left and right pressure plates 3'4' and pads 7 to fix them on the base 10, and the positioning block 1 is put into the weld groove to help Tailored welded blank positioning, placed as figure 1 As shown in (b), the advantage of this positioning is that no matter how the size...

The present invention is a double-purpose deformable welding fixture for welding linear and curved weld seams, and the fixture has linear welding slot and curved welding slot integrated onto one pedestal to reach the double-purpose aim. The double-purpose deformable welding fixture consists of one pedestal height difference structure comprising one thickness difference step and one height regulating tab for fitting different welding thickness, and one clamping screw mechanism comprising right and left pressing boards with screw holes and corresponding cap screws. It can regulate clamping force and control welding deformation by means of novel flexible location mode, and is suitable for linear and curved welding of common steel plate, high strength steel plate, aluminum plate, etc of different sizes.
Description
technical field [0001] The invention relates to the field of thin plate welding, in particular to a deformation fixture that can be used for welding straight and curved welded blanks, and is mainly used in joint welding of thin plate materials such as steel plates and aluminum plates of different thicknesses and properties. This device can realize the welding of tailor-welded blanks with different weld shape combinations, different thickness combinations, and various tailor-welded blank sizes. At the same time, the welding clamping force can be controlled by multi-point adjustment, and the flatness and smoothness of the welding edge can be well controlled. Welding gap, and finally get the weldment that meets the welding quality requirements. Background technique [0002] Welding fixtures are indispensable auxiliary equipment for metal structure welding and an important part of the welding process. During the welding process, it mainly plays the role of maintaining and ensur...
