Background technology
At present, in electric automobile, the coldplate of power electronic controller adopts the mode of friction stir welding to process conventionally, and when carrying out friction stir welding, especially foreign material welding, has higher requirement to the fixture of the quality of substrate surface, welding and equipment.
Yet the clamp fixture of using in friction stir welding mostly now is simple single pressure point structure, the surperficial depth of parallelism and the size of welding base material are had to stricter requirement.In actual welding process, due to the variation of workpiece self flatness and the distortion of welding generation, the support of plain clamp and fixedly reliability reduce, and then cause occurring the defects such as tunnel and alligatoring in welding, increase welding cost, affected production efficiency.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of clamping device of friction stir welding, can control and adjust the position of welded exemplar, reduces the requirement of welding to exemplar supporting surface, improves welding quality.
For solving the problems of the technologies described above, the clamping device of friction stir welding provided by the invention, comprise base plate, float support plate, sensor, pressure head and control module, described movable supporting plate is arranged on base plate and with the support piston rod of cylinder or the piston rod of supporting cylinder and is connected, described pressure head is with fixedly the piston rod of cylinder or the piston rod of fixer cylinder pressure are connected, the support force that described sensor is subject to for detection of welded exemplar or displacement, described sensor, support cylinder or supporting cylinder, fixedly cylinder or fixer cylinder pressure are all connected with control module.
Further, on described pressure head, be installed with fixation clip.
Better, described device comprises two pressure heads, each pressure head with one fixedly the piston rod of cylinder or the piston rod of a fixer cylinder pressure be connected, a fixation clip is installed on it.
Further, described device comprises two sensors, and each sensor is near a pressure head, and described two sensors are centrosymmetric about the center of movable supporting plate.
Preferably, described movable supporting plate below arranges three and supports cylinder or supporting cylinder, one of them supports cylinder or supporting cylinder is positioned at below the left side of movable supporting plate, and two other supports cylinder or supporting cylinder lays respectively at below the forward right side below and right lateral side of movable supporting plate.
Compare with the fixture of existing friction stir welding, the present invention has increased adjustable movement support structures, utilize support force that the welded exemplar of sensor sensing bottom is subject to or the height displacement of welded exemplar, by control module control cylinder or hydraulic cylinder, adjust the bearing height of welded exemplar, thereby reduce the requirement of welding to exemplar supporting surface, improve welding quality.In addition, the present invention is modified into two pressure head structures by single pressure head structure of plain clamp, in pressure head structure, increase fixation clip simultaneously, not only fundamentally guarantee that exemplar is reliably fixed in welding process, and increased the contact area of pressure head and exemplar, reduce the distortion of exemplar, further improved welding quality.The present invention has reduced difficulty and the cost of foreign material welding, for follow-up high-power electric and electronic controller cooling system provides good encapsulation scheme.
