The specific embodiment
Below in conjunction with accompanying drawing and optimum embodiment the present invention is described in further details.
Such as Fig. 1, Fig. 2, shown in Figure 3, be applied to the arc welding gun head slewing equipment of rectangular coordinate system welding robot, in the actual use procedure, welding job arm 6 is installed in the rectangular coordinate system welding robot in the slide type rail system on gantry installing rack 36, welding gun flexible pipe 9 is connected along 6 suspensions of welding job arm and with arc welding gun head 8, syndeton between arc welding gun head 8 and the welding job arm 6 is: fixed cover is equipped with mounting sleeve 10 on the welding gun flexible pipe 9 on arc welding gun head 8 tops, mounting sleeve 10 is fixedly connected with sleeve pipe connecting plate 42 with supporting leg, level is fixedly connected with the plate 41 that is rotatably connected on the supporting leg of sleeve pipe connecting plate 42, the bolt that is rotatably connected on the plate 41 is connected with exempts from the key axle bush, the output shaft of electric rotating machine 11 with exempt from the swelling of key axle bush and be connected.Exempting from the key axle bush is a kind of of shaft coupling, is applicable to the requirement for bearing capacity height, moves back and forth frequently in the syndeton, and exempt from key axle bush primary structure and comprise: expansion set, expansion set are set with the collar outward.During use, expansion set passes through mode and axle and the respectively swelling of the collar of friction swelling, thereby reaches the purpose that is fixedly connected with axle.In the present embodiment, for the ease of dismounting, the body bottom of exempting from the collar 40 of key axle bush is provided with notch 401, during dismounting, utilizes the instrument such as straight screwdriver to stretch into notch 401, just the collar 40 can be prized from the expansion set 43 of exempting from the key axle bush.Electric rotating machine 11 is installed on the electric rotating support 44,11 of electric rotating machines are fixedly connected with welding job arm 6 by vertical connecting plate 45, under the driving of electric rotating machine 11, mounting sleeve 10 can drive arc welding gun head 8 along with the output shaft of electric rotating machine 11 comes back rotation in the both sides of vertical connecting plate 45.In order to prevent that arc welding gun head 8 from welding process and between workbench or the workpiece direct collision occuring, the bottom of arc welding gun head 8 be provided with buffer spring 46, can effectively protect arc welding gun head 8 like this, avoid arc welding gun head 8 in collision process, to be damaged.
