A kind of weld jig
Technical field
The utility model belongs to the machinery production field, refers in particular to a kind of weld jig.
Background technology
The welding of conventional aluminum alloy TIG overlap welding spreading weld seam, in welding process because concentrating of heat can cause the sweating heat distortion, and the welding quality of conventional Welded without clamping fully can't reach stable state.Non-vacuum electronic beam now commonly used fetches and substitutes the quality that the TIG welding guarantees the aluminum alloy lapped welding, but cost is high, and equipment cost and operating cost all are 5 to 10 times of TIG welding.
Summary of the invention
The utility model provides a kind of weld jig, solving in welding process because concentrating of heat can cause the sweating heat distortion, and can't reach the problem of stable state without the welding quality of the Welded that clamps fully.
The technical solution of the utility model is: servo turnover mechanism and mount pad are rotationally connected, adjustment block is fixedly connected with servo turnover mechanism, stop is fixedly connected with adjustment block, clamping pneumohydraulic pressure-cylinder and stop is slidingly connected, top shoe is fixedly connected with the clamping pneumohydraulic pressure-cylinder, sliding block is fixedly connected with stop, upper whole profile pressure strip is fixedly connected with top shoe, lower whole profile pressure strip is fixedly connected with sliding block, on the upper whole profile pressure strip alignment pin is arranged, upper whole profile pressure strip, on the lower whole profile pressure strip temperature control device is arranged, cooling body is fixedly connected with top shoe.
The utility model has the advantage of: novel structure, by clamping pneumohydraulic pressure-cylinder, can guarantee that every place clamping point all is in stress, make and keep tight welded gaps between the product to be welded, whole profile pressure strip cooperates cooling body to guarantee that welding heat is effectively eliminated and controlled in the welding process, thereby eliminate the welding deformation and the defective that cause because of product surface distortion and welding heat, the rate of reducing the number of rejects and seconds and greatly reduce equipment investment and operating cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Servo turnover mechanism 1 is rotationally connected with mount pad 7, adjustment block 8 is fixedly connected with servo turnover mechanism 1, stop 10 is fixedly connected with adjustment block 8, clamping pneumohydraulic pressure-cylinder 5 is slidingly connected with stop 10, top shoe 4 is fixedly connected with clamping pneumohydraulic pressure-cylinder 5, sliding block 11 is fixedly connected with stop 10, upper whole profile pressure strip 6 is fixedly connected with top shoe 4, lower whole profile pressure strip 12 is fixedly connected with sliding block 11, on the upper whole profile pressure strip 6 alignment pin 9 is arranged, upper whole profile pressure strip 6, on the lower whole profile pressure strip 12 temperature control device 3 is arranged, cooling body 2 is fixedly connected with top shoe 4.
Clamp pneumohydraulic pressure-cylinder and drive top shoe and compress downwards, arrive compacted position by stop, make two Work-sheet pressings that whole profile pressure strip will weld fully to the zero clearance, begin to carry out TIG and weld.This structure can guarantee that the workpiece that welds can fit fully, guarantees the uniformity of welding.Whole profile pressure strip and workpiece are fitted fully, guarantee heat in the welding process by water circulation cooling body, derivation, by temperature control device, control the size of cooling body discharge, guarantee the heat control in the welding process.Thereby eliminate the welding deformation and the defective that cause because of product surface distortion and welding heat, the rate of reducing the number of rejects and seconds and greatly reduce equipment investment and operating cost.
