The processing method embodiment of bent axle
The processing method of bent axle is based on the bent axle flexible automation line based on robot in upper embodiment, the structure of bent axle flexible automation line based on robot describes in detail in upper embodiment, therefore do not repeat, below the process steps of bent axle is explained orally:
As shown in Figures 1 to 10, when Crankshaft Machining starts, first bent axle 10 is vertically plugged on the slot 131 on the slot plate 130 of bent axle material stock unit 100, after multiple slots 131 are populated, conveyer chain 120 starts the cycle over motion under the driving of driver 110, drive chain link 121 thereon and drive the straight line between two sprocket wheels of the slot plate 130 on chain link 121 to transport, until there being a slot plate 130 to arrive systemic presupposition position.
After slot plate 130 arrives systemic presupposition position, the flip-arm 150 on truss material stirring-up mechanism 140 starts three bent axles 10 on slot plate 130 are extracted and turned over to turn 90 degrees, and makes the bent axle 10 originally erect be converted into level.Thereafter, flip-arm 150 is vertical and level slip on sliding part 160, three first that three bent axles 10 thereon transport to bent axle slide unit 190 is kept on position 191.Bent axle 10 arrive three first keep in position 191 after, bent axle slide unit 190 level is slided, and transports bent axle 10 and arrives district undetermined, waits that truss feed robot 200 receives.
Truss feed robot 200 upper three bent axles 10 on bent axle slide unit 190 are captured and carry out on truss vertically, level transport, arrive and carry out first centreless grinding processing at centerless grinder 1.
After first centreless grinding operation completes, the blanking crawl arm of truss blanking robot 300 moves to First centerless grinder 1, is taken out and slides into second by bent axle 10 and keep on position 331, makes three bent axles 10 be temporarily stored in due-in district 330.Certainly, according to the process requirements that bent axle 10 is different, centreless grinding operation may need to carry out one to three times, if second time or the centreless grinding operation of third time need to be carried out, specializing in and in second truss feed robot 200 of second centerless grinder 1 and second truss blanking robot 300, bent axle 10 circulates the carrying step of first centreless grinding and carry out second time centreless grinding processing, the method that the method for centreless grinding processing for the third time is processed with third time centreless grinding is identical.
After last one centreless grinding operation completes, bent axle 10 is temporarily stored in due-in district 330 by truss blanking robot 300, now needs the bent axle 10 between meticulous centerless grinder 1 and eccentric grinding machine 2 to carry.It is provided with the first blanking supply line 400 between centerless grinder 1 and eccentric grinding machine 2, being responsible for the truss feed robot 100 of centerless grinder 1 without sole duty for one and capture and be carried in the second conveyer chain 410 of the first blanking supply line 400 by three bent axles 10, in the second conveyer chain 410, V-type seat makes bent axle 10 fix and stablizes transport.
When the first blanking supply line 400 transports close to the first six-DOF robot 500, two bent axles 10 are carried out capturing and be transported to sole duty and carry out eccentric location work at the bent axle detent mechanism 800 that first step bias grinder is made by full-time the first six-DOF robot 500 made in first step bias grinder, then are transported in First bias grinding machine 2 carry out eccentric grinder work.Owing to eccentric grinder sequence needs one or more eccentric grinding machine 2 to realize according to the processing situation that bent axle 10 is different, therefore it is provided with First Transition supply line 550 between adjacent eccentric grinding machine 2, full-time the first six-DOF robot 500 in First bias grinding machine 2 is to being placed on First Transition supply line 550 temporary after being taken out from eccentric grinding machine 2 by bent axle 10 and transporting, it is transported at second eccentric grinding machine 2, the bent axle carrying operation that circulation is as consistent in the most eccentric mill.
After the most eccentric last grinder sequence, two bent axles 10 are transported to the second blanking supply line 600 between eccentric grinding machine 2 and thrust grinding machine 3 by the first six-DOF robot 500 of last eccentric grinding machine 2 full-time simultaneously, bent axle is transported bed 2 side of turning a millstone to end by the second blanking supply line 600, the second six-DOF robot 700 of full-time first step thrust surface grinder sequence capture.
Two bent axles 10 are transported in bent axle detent mechanism 800 carry out eccentric location one by one by the second six-DOF robot 700 simultaneously, after bent axle 10 is transported in thrust surface grinding machine 3 carry out thrust surface processing again, after first step thrust surface completion of processing, second six-DOF robot 700 is placed in the second transition supply line 750 temporary and transports, rear continuation second step thrust surface grinds processing, and its carrying step carries operation with reference to first step thrust surface.
After final step thrust surface grinder sequence, two bent axles 10 are taken out from thrust surface grinding machine 3 by the second six-DOF robot 700 of last thrust surface grinding machine 3 full-time, and are placed on discharging haul road, carry out bent axle 10 discharging.
Finally it is emphasized that; the foregoing is only preferred embodiment of the present utility model; it is not limited to this utility model; for a person skilled in the art; this utility model can have various change and change, such as the increase of bent axle material stock unit upper position quantity, the change etc. of grinding machine group Internal abrasive machine value volume and range of product, all within spirit of the present utility model and principle; the any modification, equivalent substitution and improvement etc. done, within should be included in protection domain of the present utility model.
