With reference to figure 9-12, provide a kind of grip device 80, accurately and effectively to assemble and to weld dish 15 on the axle 14 of supporting into horizontal pattern.As shown in FIG., device 80 comprises dish location and the welding anchor clamps 81 that are mounted to the 82 one-tenth operative relationship of lathe that are suitable for.Spindle stock 83 carries chuck 84, but the chuck corotation clamp the minor axis 17 on axle 14 the end and reach the rotation of Control Shaft 14 in lathe.At the other end of axle 14, minor axis 17 engages the back dead centre 85 of the tailstock 87 of lathe.

Anchor clamps 81 mats are loaded on the understructure 88 of anchor clamps on 90 one-tenth plankers that are slidably engaged 89 of guide rail with lathe and are installed in lathe.Carriage box 91 portabilities of planker 89 drawdowns in lathe 82 the place aheads are common in order to move the device of anchor clamps 81 along leading screw 92.Fast moving should be carried out by handwheel 93.Anchor clamps 81 have the control increment type to move should be by carrying out such as stepper motor 94, rotating band 95 is connected to leading screw 92 to motor by for example slowing down regularly, and this time connects and generally provide 5: 1 deceleration.The running of motor 94 is by the cyclelog control of case 97 representatives, and controller is provided with the control panel of the digit manipulation control knob 98 that has one group of row on it.

The framework 99 of anchor clamps 81 is by base 88 fixed carrying, and is cross-placed on the dish net shaft assembly 13, and when carrying out each dish of welding on axle 14 time, anchor clamps are by a suitable spacing distance to each dish 15 reach net dish.One of thereon installing plate or plate 100 pass plate 100 and have with the concentric through hole 101 of axle 14 can be by being loaded on one of dish 15 on axle diameter to move the various operating mechanisms dresses that carry anchor clamps on the face before the framework 99.

When the dish weld job begins, will have loose engagement and be loaded in the lathe, and make anchor clamps 81 place the starting end of its operation stroke in spools 14 of each dish 15 of contiguous its end that is connected with tailstock 85, as shown in Figure 9, that is be close to the left end of the assembly of headstock 83.Dish 15 with immediate loosening support places the suitable position that is engaged by one group of same groove positioning roller 102 of separating along the circle spacing then.Each roller is loaded on the plate 100 into about 120 ° of intervals and operatively around through hole 101.Each roller 102 be used for fixing order a dishful of 15 in the accurate sagittal plane of axle 14, the welded joint 103 welding dish 15 that carried of anchor clamps 81 are on axle 14 simultaneously.

The cooperation of each positioning roller is installed and is operated by can this all identical mechanism reaching at each roller, and each mechanism comprises a rocking arm 104, but relevant roller is loaded on one of rocking arm end by a for example minor axis head 105 free rotaries.An end of axle 107 is fixed in the other end of arm 104, but axle passes the bearing 107 that is carried by plate 100 and is loaded on plate 100 by free rotary.Side within the plate 100 that is as the criterion with framework 99, as the clear demonstration of Figure 11, axle 107 has arm fixedly connected thereto 108, and arm is connected in the piston rod 109 of direct active cylinder actuator 110 turnably, and the bottom of actuator is connected and fixed on the carriage 111 on the plate 100 turnably.Therefore, during operate actuator 110, relevant roller 102 is suited at dish position location (shown in dotted line among solid line among Figure 10 and Figure 11) and returns between the disengaging configuration (as shown in phantom in Figure 10) and move.

For cooperating the tooth 23 of dish 15, roller 102 has the degree of depth is enough to hold tooth, and the cannelure 102a of the face of slideable joint dish, does not make the hub of indented joint roller.For guaranteeing this kind positioning relation, each roller-activation mechanism is provided with counter stop device 112, be limited among the locating slot 102a admit dish the tooth edge in desired depth.Near two rollers 102 of clamp base 88, counter stop device 112 is loaded within the plate 100 on the face, and is configured to be engaged by the outer end of stretching out piston rod 109 of actuator when the location of affiliated roller 102 stroke stops in the position.Owing to be subjected to spatial constraints, as shown in the figure, the actuator 110 of top roller 102 can make 102 one-tenth positioning relations of relevant roller when piston rod 109 shrinks, and when withdrawal roller 102, the piston rod of the actuator 110 of this roller stretches out.Therefore, the counter stop device 112 of top roller operating mechanism is mounted to from the top of framework 99 and hangs down, and when relevant roller was in the orientation, location, the counter stop device was engaged by the shoulder of the counter stop on the piston rod 109 of associated actuator 110 113.Each counter stop member 112 can be adjusted and be reached best counter stop effect with relevant roller.

Each welded joint 103 is mounted to can swing the relevant posetionof weld of the dish that enters and leave and need add welding 15.A purpose for this reason, each welded joint 103 is loaded on and carries on the arm 114, carries the arm 114 fixed vertical rotating shafts 115 that are loaded on, and end is loaded in the bearing arrangement 117 on the top of carrier structure 89 under the axle 115.Two sides of the through hole 101 of plate 100 respectively are equipped with and do not stop one of through hole axle 115.Hold on the axle 115 to be loaded in the carriage 118 that is fixed on the plate 106, terminal part 119 extend out to the carriage top on carriage and the axle.The crank arm 120 fixed ends 119 that are loaded on, crank arm is turnable to connect square end portion outside the piston rod 121 of directly effect strength actuator 122 of the through hole 123 that passes plate 101, and the other end of actuator is connected in the fixed carriage that is connected in the top of framework 99 and hangs down 124 turnably on it.Through planting configuration thus, each welded joint 103 can be activated and swing between welding pattern (Fig. 9,10, and 12 solid line) and disengaging pattern (dotted line of Figure 12) by its actuator 122.For guaranteeing that welded joint 103 is in when the welding pattern for the purpose of the suitable welding orientation, each 115 carries a counter stop arm 125(Figure 10), the counter stop arm can engage with the counter stop shoulder member 127 that plate 100 is carried, as the clear demonstration of Figure 12.

When the operation cycle of device 80 began, anchor clamps 81 moved to the starting position that abuts headstock 83 by for example travel mechanism's handwheel 93.At this moment, whole group dish 15 has been assemblied on the axle 14, presses to the vehicle tail end of axle 14.And calibration roller 102 and welded joint 103 are positioned at returns disengaging configuration separately.The position that should be fused to first dish 15 on the axle 14 on the headstock end of each calibration roller 102 aiming axis 114.Handle (in this example with manual control) then and answer first dish 15 of welding to aim at each calibration roller 102, as the clear demonstration of Fig. 9, the opening portion of the annular indexing trough 102a of roller is opened and guides the dish edge to enter in the locating slot.For mobile calibration roller 102 and welded joint self-retracting position to indexing position, the actuating summary is shown in the pneumatic system 128 of Figure 13.This system from a source 128 through manage 130 and subsequently filtration and amount counter device 131 obtain suitable pressure as 551.2 kPas compressed air.When operation is negative when preparing the dish location, depress the footboard of the two-way function valve 132 of neutrality under normal condition according to the direction of arrow 133, therefore, actuator 110 is driven each roller 102 to the position location of matching separately by excitements.The operator unclamps sufficient actuating valve then, and valve promptly returns neutral holding position.When desiring actuating calibration roller 102 because of any reason, can step on valve 132 according to reverse actuating foot shown in the arrow 134 as the operator.

Suppose to answer the dish 15 of welding to be positioned to the degree of operator's satisfaction by roller 102, the operator one of promptly handles on the control panel 98 control element and begins by one of the performed action order automatically of controller 97, comprising operation one electric screwed pipe valve 135, this valve is regulated and is reduced device 137 through a pressure and is connected to force pipe 130, thereby makes welded joint 103 disengaging configuration shown in the dotted line in Figure 12 be rocked to the posetionof weld shown in the solid line.Welded joint is operated automatically, otherwise otherwise on posetionof weld with a welding mode with regard in the circumferential groove 27 within the dish 15 in fact along diameter mutually contact and within dish 15 fixed points are fused in the circumferential groove 27 in fact along a diameter contact and dish 15 fixed points are fused on spools 14 mutually.Activate lathe 82 then, with the dish 15 of stable and slower rotary speed rotating shaft 14 through the fixed point welding.When axle and dish rotation, positioning roller 102 continues its positioning function, rotation with the dish 15 that is engaged rotates freely, and after fixed point welding one short distance, control welded joint 103 is ended welding work, operate welded joint welding one longer rotary distance then, control welded joint again to end welding one short distance, last operation welded joint welding one longer distance.When arriving the fixed point welding area, welded joint 103 is ended welding work.So, should install a kind of, the welding pattern keeps and finishes circulation and make within the dish 15 or three minor arcs of hub periphery are fused on spools 14, reaches weldless in three short distances.Certainly, during as needs, this order to the axle of difference and (or dish) but the device change or when needing, even can be contunuous wedling.Yet, through finding that being uniformly distributed in the intersegmental weak point weldless of longer welding helps preventing prying at interval.

In automatic circulation pattern, when the welding stage finished, electric screwed pipe valve 135 was operated automatically and is reversed welded joint actuator 122, makes welded joint 103 be rocked to the disengaging configuration of not working, shown in the dotted line of Figure 12.The 138 quilt actuatings simultaneously of two-way electric screwed pipe valve, and step on valve 132 with the bypass foot,, divided wheel or roller-activation device 110 regain calibration roller 102 so that reversing.The dish 15 through welding is decontroled in this measure, and in automatic operation mode, causes stepper motor 94 operations and rotation lead screw 92 makes anchor clamps 81 along the advance increment at a dish interval of axle 14.At this moment, inferior a dishful of 15 can be moved to posetionof weld, and carry out automatically roller location and welding stage.In full-automatic operation, two-way electric screwed pipe valve 138 can be by timer control, and timer provides with hand and moves time a dishful of 15 appropriate times to posetionof weld, as owing to any reason causes deficiency of time, or operator's desire is when quickening positioning action, but actuating footboard control valve 132.Should the person of understanding, certainly, various manual buttons or bundle of spheres can be arranged on control panel 98, be used for for example beginning operation, select to open and close control, welded joint is shaken in the Control Shaft rotation, sequential control, the operation automatically of beginning positioning roller etc.In any case, carry out each dish 15 of order welding continuously on axle 14, all accurately be fused on the axle until whole dish.Then, send anchor clamps 31 back to abut headstock 83 starting position, remove shaft assembly 13 through welding, and will time one 14 and the loosening whole dish 15 of need welding thereon of supporting be installed in the lathe 82, lay equal stress on and cover weld job.

Except that welding dish 15 is on single-piece axle such as axle 14, if need the welding dish in shorter mould hub or shaft part such as shaft part 14a(Fig. 2) when going up, with will as the axle among Fig. 2 14 ' one of the total length axle be loaded in the lathe 82, reach each shaft part 14a be loaded on the axle with regard to end to end relation.Carry out each dish 15 of welding on the overall length axle according to aforementioned manner then.Therefore, between will keeping between each welding dish on the overall length of each mold shaft section every, so be loaded on when using on one of the dish net arrangement axle when each mold shaft section, the dish net of each adjacent dish net shaft assembly is with suitable interleave in the net bed of dish net arrangement.
