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.
