Summary of the invention
The technical problem that the present invention solves is to provide a kind of simple in structure, highly versatile, quick, the easy to operate location of registration clamps welder.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
For locating fast the welder of electric EGR valve, comprise laser-beam welding machine and positioning tool, described positioning tool comprises base plate, the left vertical of base plate upper surface is provided with side plate straight up, the top of side plate is provided with the positioning seat that parallel base plate arranges, and positioning seat is provided with for locating the groove of electric EGR valve slide block to be welded away from one end of side plate; The right side of described base plate upper surface is provided with two guide rails that are parallel to each other, on guide rail, be sliding combined with sliding shoe, on sliding shoe, be vertically installed with straight up for the buck plate of cylinder is installed, sliding shoe is positioned in the U-shaped groove at base plate center by tie down screw; The central axes of the central axis of described cylinder pressure head and positioning seat groove.
Improvement of the present invention is: described two corresponding inner sides of guide rail are set to the centroclinal inclined-plane of base plate, and the lower surface of sliding shoe is equipped mutually with the inclined-plane of two guide rails.
Improvement of the present invention is: on the upper surface of described sliding shoe, be provided with the handle moving left and right along guide rail for promoting sliding shoe.
Improvement of the present invention is: groove the inner of described positioning seat is provided with for holding out against the back-up block of electric EGR valve slide block to be welded.
Improvement of the present invention is: the hand of the cylinder on described buck plate is pulled on the lateral wall that valve is arranged on side plate.
Improvement of the present invention is: the center of described cylinder pressure head is provided with circular blind hole, in circular blind hole, is fitted with silicagel pad.
Improvement of the present invention is: between described side plate and base plate, by left reinforcement, be fixedly connected with; Between sliding shoe and buck plate, by right reinforcement, be fixedly connected with.
Owing to having adopted above technical scheme, the invention technological progress is:
The present invention is simple in structure, easy to use, registration, versatility are high.Utilizing on the basis of common laser bonding machine, directly using the slide block of soldered electric EGR valve as positioning datum, eliminating inconsistent the produced welding position deviation of each valve body clamping.Utilize cylinder clamping center-pole and slide block, eliminated the gap between slide block die cavity section and center-pole section, guaranteed the uniformity of valve body stroke in batch production, improved the performance of valve body.In addition, in the time need to welding the valve body of different size model, only need unclamp lock-screw, regulate sliding shoe to lock again behind suitable position, can clamp the center-pole of different length; When slide block size changes, only need by changing the positioning seat on side plate, improved versatility of the present invention.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further elaborated.
For locating fast a welder for electric EGR valve, comprise laser-beam welding machine and positioning tool, positioner is fixed on laser-beam welding machine, for locating and clamp electric EGR valve to be welded.
The structure of described positioning tool as shown in Figure 1, comprise base plate 1, side plate 4, guide rail 16, sliding shoe 14 and buck plate 11, buck plate is used for assembling cylinder 12, side plate is for installing the slide block of electric EGR valve to be welded, cylinder is for holding out against electric EGR valve center-pole to be welded at slide block, to complete the location of slide block and center-pole.
The present invention, in assembling process, must guarantee the central axis of cylinder pressure head and the central axes of positioning seat groove of cylinder, to guarantee that center-pole and the slide block of electric EGR valve to be welded can weld precisely.
The present invention before use, first according to the concrete size of the size of electric EGR valve valve body to be welded and center-pole and slide block, change the positioning seat 5 mutually equipped with slide block, and pull handle 17, the preliminary distance regulating between sliding shoe 14 and side plate 4, then by tie down screw 15 and coordinate U-shaped groove that sliding shoe 14 is locked on guide rail.Secondly, by the slider surface of valve body upward, pack in the groove of positioning seat, stir hand and pull valve 3, make the cylinder pressure head of cylinder compress center-pole end, coordinate the back-up block in positioning seat groove that center-pole 7 and slide block 6 are clamped.Finally, regulate the focusing head of laser-beam welding machine, the mobile extremely initial position of welding of head of focusing, after input welding track program, program of dry run, has problem to revise, and out of question beginning welded.
After welding completes, stir hand and pull valve 3, unclamp cylinder 12, take out valve body, observe the shape of weld, welding frequency and the current strength of suitable adjusting laser-beam welding machine, so just determined all welding parameters and welding procedure.Welding afterwards only needs directly to pack the slide block of valve body into slide block locating piece, stirring hand pulls valve 3 and opens cylinder, can be directly by determined program before, directly weld, without again regulating initial position, so just guarantee the high efficiency in batch production, greatly reduced production time.
