input belt pulley 16 are separately fixed on the output revolving shaft and input rotating shaft of gear reduction box, be provided with the multi-stage gear transmission between input rotating shaft and the output revolving shaft, when an angle was rotated in the input rotating shaft, output revolving shaft rotated corresponding angle by fixing speed ratio.A profile of tooth output belt pulley 17 is fixed on the rotating shaft (not shown) of stepper motor 4, odontoid belt 5 is connected transmission with profile of tooth output belt pulley 17, profile of tooth input belt pulley 16 respectively, makes profile of tooth output belt pulley 17, profile of tooth input belt pulley 16 form the odontoid belt transmission.Dead axle 40 is positioned at the top of base 15 and fixedlys connected with base 15, and the outer rotary table 3 of annular is positioned at the top of base 15 and is installed in pivotally on the dead axle 40 by Bearning mechanism, and this outer rotary table 3 can rotate around fixed axis 40.Interior disk 10 is fixed on the dead axle 40 and is positioned at the top of the center of outer rotary table 3.In particular, dead axle 40 is fixedlyed connected with interior disk 10 after passing centre bore 107 and the centre bore 1003 on the interior disk 10 on the outer rotary table 3, dead axle 40 and centre bore 107 matched in clearance.Bearing arrangement described here comprises the clutch shaft bearing 20 and second bearing 14, and the clutch shaft bearing 20 and second bearing 14 are rolling bearings, and each rolling bearing comprises an inner ring, an outer ring and a plurality of rolling element, and rolling element rolls between inner ring and outer ring.The outer ring of clutch shaft bearing 20 is installed in the clutch shaft bearing hole 106 on the outer rotary table 3, cooperating between this outer ring and the clutch shaft bearing hole 106 is that standard cooperates, the inner ring of clutch shaft bearing 20 is sleeved on the dead axle 40, cooperating between this inner ring and the dead axle 40 also is that standard cooperates, the outer ring of second bearing 14 of described bearing arrangement is installed in second dead eye 102 on the outer rotary table 3, cooperating between this outer ring and second dead eye 102 is that standard cooperates, in the inner ring of second bearing 14 is sleeved on the step axle 1001 of disk 10, cooperating between this inner ring and the step axle 1001 is the standard cooperation.Described outer rotary table 3 preferably supports and is fixed on the output wheel 160 of dispenser 6, promptly fixedlys connected with output wheel 160 with the screw 103 on the outer rotary table 3 by screw.Its advantage is that transmission progression is few, simple in structure, and the transmission accuracy height, but it requires the output shaft of dispenser 6 can bear bigger axial force, the gross weight that this axial force can be enough to bear outer rotary table 3 and be fixed on all parts on the outer rotary table 3.Another kind of alternative alternative plan (not shown) is that outer rotary table 3 is installed on the base 15 by a supporting device (not shown), and is in transmission connection by a transmission mechanism (not shown) and dispenser 6.Supporting device described here comprises first annular bearing surface that is formed on the outer rotary table 3, is fixed on the supporting base with second annular bearing surface and at least 3 rolling elements on the base 15, wherein first annular bearing surface and second annular bearing surface respectively with the axis normal of dead axle 40, each rolling element rolls with first annular bearing surface, second annular bearing surface respectively and cooperates.Transmission mechanism described here comprises that is fixedly mounted on a circular wheel on the outer rotary table 3 and concentric with the center of rotation of outer rotary table 3, and the output wheel 160 of circular wheel and dispenser 6 is in transmission connection.Here so-called being in transmission connection is meant the connection of transmitting rotation, all can as gear drive, chain transmission, belt transmission.Owing to increased the one-level transmission, so alternative plan is lower than the transmission accuracy of first scheme shown in the drawings, structure relative complex simultaneously, but when the weight of outer rotary table 3 surpassed the rated load of axial force of output shaft of dispenser 6, alternative plan was necessary.
Owing to adopted the relation that is connected and installed of above each parts, station dial formula automatic welding device of the present utility model has following drive connection: the rotation of stepper motor 4 drives profile of tooth output belt pulley 17 and rotates, the rotation of profile of tooth output belt pulley 17 drives profile of tooth input belt pulley 16 by odontoid belt 5 and rotates, the power shaft of the rotation driven gear reduction box of profile of tooth wheel for inputting belt 16 rotates, and drives rotation drive output wheel 160 rotations of output shaft then by the gear drive of gear reduction box.In first scheme shown in the drawings, the rotation of output wheel 160 directly drives outer rotary table 3 and rotates; And in another alternative plan, the rotation of output wheel 160 needs to drive circular wheel by the formed transmission mechanism of being in transmission connection of the output wheel 160 of circular wheel on the outer rotary table 3 and dispenser 6 and rotates, and the rotation of circular wheel drives outer rotary table 3 and rotates.From above drive connection as seen, there are the following main distinction in first scheme and alternative plan: the axle center of the fixed axis 40 of first scheme must be concentric with the axle center of the output shaft of gear reduction box, the pivot that is outer rotary table 3 is concentric with the pivot of the output shaft of reduction box, in this case, a dispenser 6 can only drive an outer rotary table 3.And under alternative plan, it is concentric that the axle of the axle center of fixed axis 40 and the output shaft of gear reduction box does not need, i.e. the pivot decentraction of the pivot of outer rotary table 3 and reduction gearbox output shaft, and its advantage is to realize that a dispenser 6 can drive a plurality of outer rotary tables 3.
Four manipulator mechanisms are installed on the circumferential periphery of outer rotary table 3 in uniform way, rotate on the circumferential plane space that forms at manipulator mechanism, circular path along the manipulator mechanism process is evenly equipped with four stations successively, be material level 32, welding processing position 29 and following material level 30 on material level 33, the contact on the touch panel, wherein welding processing position 29 is near upper holder 1 and lower fixed frames 2.Described stepper motor 4 can adopt the conventional intermittently motor of type of drive, rests once after promptly commentaries on classics once (is promptly driven and moved a step).Its per step drives and makes outer rotary table 3 rotate 90 °, rest at every turn make four manipulator mechanisms on the outer rotary table 3 rest on the corresponding above-mentioned touch panel material level 32 on material level 33, the contact, welding processing position 29 respectively exactly, down on these four stations of material level 30.Stepper motor 4 of the present utility model adopts and waits the step to drive, i.e. the angle that driving of per step is rotated rotating shaft equates that the time span of at every turn resting also equates.Because the utility model has adopted four structures that station is uniform, so the transmission speed ratio between stepper motor 4 and the outer rotary table 3 must meet following condition: stepper motor 4 drives to move a step and makes outer rotary table 3 rotate 90 °, and rests at every turn and must make four manipulator mechanisms on the outer rotary table 3 rest on the position of described four stations respectively.Each manipulator mechanism comprises that one is gone up mechanical arm assembly 7 and a following mechanical arm assembly 8, two last top cylinder units 11 are fixedly mounted on respectively on the base 15 of material level 33 on the touch panel, following 30 two stations of material level, go up the below that top cylinder unit 11 lays respectively at outer rotary table 3 for these two, and cooperate with four following mechanical arm assemblies 8 shake-up respectively.Top cylinder unit 11 comprises top 111, cylinder 112 and L template 113 on each, cylinder 112 is fixed on the base 15 by L template 113, top 111 is fixed on the
