The invention has the beneficial effects as follows: this welding tooling is for the Iranian subway with arc groove and arcwall face structure, the unique design of Wuhan dike linea angulata subway draw beam weldment, the mechanisms such as the locating piece on its pedestal and clamping screw can by the special construction fixing and locking with arc groove and arcwall face on draw beam, its disc base can with the positioner interface disk Rapid matching of welding robot, thus make draw beam weldment can realize accurately on positioner, reliable quick position, and then automatically complete weld job by welding robot, while raising welding efficiency and welding quality, the potential safety hazard existed when also having stopped operating personnel's traditional-handwork weld job.This frock also has simple and practical, easy to operate, with low cost, is convenient to advantages such as popularizing.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further details.
As shown in Figures 1 to 4, urban rail car draw beam welding tooling of the present invention comprises: disc base 1, pedestal 2, locating piece 3, horizontal fishbolt 4, located lateral bolt 5, longitudinal fishbolt 6 and follower bolt 7.
Disc base 1 is provided with 6 rectangular groove 1-1, and these 6 rectangular groove 1-1 are evenly distributed on disc base 1, and the angle between adjacent two rectangular groove 1-1 is 60 °, and the top of each rectangular groove 1-1 all communicates with a circular hole 1-2.Disc base 1 is the positioner interface circular tray designs copying OTC welding robot, and its planform and size are all identical with positioner interface disk.Therefore can with positioner interface disk Rapid matching, realize accurately, be reliably fixedly connected with.
Pedestal 2 comprises two longerons and a crossbeam, and longeron is forge piece of step type structure, and two longeron cocurrent and parallels are placed, and beam vertical is welded on the rear end of two longerons.The front end, upper surface of two longerons is equipped with a groove 2-1, center bottom groove 2-1 is provided with a screwed hole 2-2, the rear end sidewall of two longerons is equipped with a cross bolts hole 2-4, the center of beam side wall is provided with a longitudinal bolt hole 2-3.
Locating piece 3 is rectangle structure, its two ends are respectively provided with a radial strip through hole 3-1, and the width of this locating piece 3 is less than the width of groove 2-1, can to slide a little adjustment to make locating piece 3 in groove 2-1, adapt to the structure of workpiece to be fixed, and workpiece is reliably fixed.
The bottom surface of pedestal 2 two longerons is welded on disc base 1, need make the long limit of two longeron lower surfaces respectively perpendicular to two rectangular groove 1-1 diametrically same on disc base 1 during welding, and not rectangular with other groove 1-1 is crossing as far as possible.
Horizontal fishbolt 4 and located lateral bolt 5 are threaded with the longeron sidewall of pedestal 2 respectively by a cross bolts hole 2-4, longitudinal fishbolt 6 is threaded with the beam side wall of pedestal 2 by longitudinal bolt hole 2-3, two follower bolts 7 are connected with screwed hole 2-2 through strip through hole 3-1, and locating piece 3 is slidably connected by strip through hole 3-1 and two follower bolt 7.
Shown in composition graphs 5, treat that the Iranian metro traction beam of welding comprises two bent plate compositions 8 (only having drawn a bent plate composition in figure) and a cylindrical drum 9, bent plate composition 8 is by flat top 8-1, curved plate 8-2, first side plate 8-3, second side plate 8-4, 3rd side plate 8-5 and the 4th side plate 8-6 is formed, first side plate 8-3 and the second side plate 8-4 is cambered plate, 3rd side plate 8-5 and the 4th side plate 8-6 is surface plate, second side plate 8-4, an arc groove 8-7 is provided with between 3rd side plate 8-5 and the 4th side plate 8-6, welding tooling of the present invention is the auxiliary locating tool equipment for welding weld seam between curved plate 8-2 and cylindrical drum 9.
During embody rule urban rail car draw beam of the present invention welding tooling, first rotate horizontal fishbolt 4 and longitudinal fishbolt 6, in the screw that their screw rod end is retracted on pedestal 2 sidewall respectively, then rotate located lateral bolt 5 and the madial wall of its screw cap end and pedestal 2 is adjacent to, then two follower bolts 7 are unloaded together with locating piece 3 from groove 2-1.The end face outside of disc base 1 is docked with the positioner interface disk of OTC welding robot, and with coordinating of rectangular groove 1-1, disc base 1 and positioner interface disk is connected by follower bolt.
Draw beam horizontal suspension to be welded is located, and makes its arc groove 8-7 Open Side Down to place.Bent plate composition 8 is inserted draw beam welding tooling of the present invention, flat top 8-1 is against on the inner side end of disc base 1, and makes the 3rd side plate 8-5 parallel with the bolt end face of located lateral bolt 5; Rotate horizontal fishbolt 4, located lateral bolt 5 and longitudinal fishbolt 6 respectively, horizontal fishbolt 4 is made to hold out against the second side plate 8-4, located lateral bolt 5 holds out against the 3rd side plate 8-5, longitudinal fishbolt 6 holds out against the first side plate 8-3, and then by the second side plate 8-4, the 3rd side plate 8-5, the first side plate 8-3 clamping and positioning respectively.Then, then locating piece 3 is put into two groove 2-1, and block the madial wall of arc groove 8-7 with locating piece 3.The adjustment position of locating piece 3 in two groove 2-1, when the lower end sidewall of locating piece 3 and the sidewall of groove 2-1 are adjacent to, are fixed locating piece 3 by two follower bolts 7, and then completes the assembling process of draw beam workpiece and welding tooling of the present invention.
So far, draw beam workpiece to be welded completes and the assembling of positioner and location together in company with this frock, and the weld seam between the curved plate 8-2 of draw beam and cylindrical drum 9 can be completed according to the position relationship of weld seam in space automatically by OTC welding robot.
