Abstract
The utility model discloses a radiator friction stir welding's special fixture is specially disclosed, including the board, set up two anchor clamps bodies of relative position adjustable on the board, the anchor clamps bodies on be provided with the holder, the holder including the clamping face with work contact and with the transition face of perpendicular settings of clamping face, the edge of meeting with the face of weld of work piece on the transition face is provided with the dimple, is provided with in the dimple and draws the welding block, that states draws the welding block back of packing into, the protrusion is in the transition face surface, for prior art, because the messenger moves back the sword keyhole stays outside the radiator and save and do the processing to the radiator surface keyhole specially, has reduced production making's processing procedure, the efficiency of having saved the cost -push, anchor clamps use rotatory pneumatic cylinder can guarantee that fix is firm and the clamping is quick simultaneously.
Description
Technical field
The utility model relates to a kind of special fixture of friction stir welding, particularly relates to a kind of special fixture of radiator friction stir welding.
Background technology
Along with the development of science and technology, electric power has been the resource that the whole mankind can not lack, no matter be high ferro, motor-car, hospital, bank, subway, enterprise etc., all requirements at the higher level are proposed to electric power, so high-power IGBT, SCR, the devices such as electric capacity serve bears the important task that this improves electric power mission, but along with IGBT, SCR, the extensive uses such as electric capacity, IGBT, SCR, the power of electric capacity is also more and more higher, application is more and more in the industry, but power is better in use more easily produces a large amount of heats, need timely by the radiator of larger area of dissipation, rapidly heat is shed, so a lot of radiator company releases, contact area is larger, the more higher aluminium alloy heat radiators of gear piece, but aluminium alloy heat radiator is limited to the reason of extrusion die tool equipment and cost, the radiator can not producing width very large according to wish completely squeezes type, can not meet the requirement of high-power heat-dissipation, made the processing method of radiator into friction stir welding afterwards, use Friction stir welding well can make up the deficiency of extrusion die tool equipment, use this technique can produce the wider aluminium alloy heat radiator of width, but spreader surface is limited to the mixing needle of cutter front end and leaves withdrawing keyhole at the end of welding, conventional way directly will leave a tip cut-off of keyhole or adopt the mode of riveted joint and argon arc welding filling, but the processing procedure that these modes not only increase production also additionally increases the cost of production.
Summary of the invention
The purpose of this utility model be to overcome the deficiencies in the prior art and provide a kind of can rapidly and efficiently for the fixture in industry splicing radiator friction stir welding processing procedure, and withdrawing keyhole can be made to stay outside radiator.
For achieving the above object, the utility model have employed following technical proposals:
The special fixture of this radiator friction stir welding, include board, be arranged at two clamp bodies that relative position on board is adjustable, described clamp body is provided with holder, described holder includes and the clamping face of functional contact and transition face vertically disposed with clamping face, the edge that transition face connects with the solder side of workpiece is provided with dimple, is provided with and draws welding block in dimple.
Described draw after welding block loads, protrude from transition face surface.
Described clamp body also includes rotating liquid cylinder pressure and supports the gripper shoe of this rotating liquid cylinder pressure.
The output shaft of described rotating hydraulic cylinder is provided with briquetting.
Described welding block is fastened in dimple.
Described welding block is fixed by screws in dimple.
By technique scheme, draw welding block, from achieving following beneficial effect owing to increasing in friction stir welding withdrawing position:
Outer and save and specially spreader surface keyhole is processed owing to making withdrawing keyhole stay radiator, decrease the processing procedure of production, provide cost savings and add efficiency; The rotating liquid of fixture use simultaneously cylinder pressure can ensure product fixation and clamping is quick.
Accompanying drawing explanation
Fig. 1 is the special fixture schematic perspective view of radiator friction stir welding.
Fig. 2 is another schematic diagram of special fixture of radiator friction stir welding.
Fig. 3 is the partial enlarged drawing in Fig. 2.
Detailed description of the invention
Below in conjunction with accompanying drawing to this utility model and go out further description.
As shown in Figures 1 to 3, the special fixture of this radiator friction stir welding, include board 1, be arranged at two clamp bodies 2 that relative position on board is adjustable, described clamp body is provided with holder 22, described holder includes and the clamping face 222 of functional contact and transition face 224 vertically disposed with clamping face, the edge that transition face connects with the solder side of workpiece is provided with dimple 3, be provided with in dimple and draw welding block 4, the described welding block that draws is fixed in dimple by screw 5, after loading, protrude from transition face surface; Clamp body described in addition also includes rotating liquid cylinder pressure 24 and supports the gripper shoe 26 of this rotating liquid cylinder pressure, and the output shaft 262 of described rotating hydraulic cylinder is provided with briquetting 28.
Time this special fixture uses, product to be welded is put into clamp body, then will draw welding block is arranged in dimple, then vice is locked, next the switch of rotary hydraulic cylinder is opened again, regulate briquetting to make oil cylinder locking product, then the screw at welding block place is drawn in locking, finally starts friction stir welding program and starts welding.Product starts friction stir welding after using fixture clamping, cutter withdrawing position is stayed and draws on welding block, only instrument need be used to get rid of and draw welding block after welding like this terminates, and product two end faces use drawing process process.
Compared with prior art, outer and save and specially spreader surface keyhole is processed owing to making withdrawing keyhole stay radiator, decrease the processing procedure of production, provide cost savings and add efficiency; The rotating liquid of fixture use simultaneously cylinder pressure can ensure product fixation and clamping is quick.
Certainly described welding block also can be fixed in dimple by the mode of clamping, all belongs to protection domain of the present utility model.
