The processing method embodiment of bent axle
The bent axle flexible automation line based on robot of the processing method of bent axle based in upper embodiment, the structure of the bent axle flexible automation line based on robot is described in detail in upper embodiment, therefore do not repeat, below the process steps of bent axle explained orally:
As shown in Figures 1 to 10, when Crankshaft Machining starts, on slot 131 on the first slot plate 130 that bent axle 10 is vertically plugged in to bent axle material stock unit 100, multiple slots 131 are by after plug-in mounting, conveyer chain 120 starts shuttling movement under the driving of driver 110, drive the chain link 121 on it and drive slot plate 130 straight line between two sprocket wheels on chain link 121 to transport, until there is a slot plate 130 to arrive systemic presupposition position.
When slot plate 130 arrives behind systemic presupposition position, the flip-arm 150 on truss material stirring-up mechanism 140 starts three bent axles 10 on slot plate 130 to extract and turn over to turn 90 degrees, and makes the original bent axle 10 of erectting be converted into level. Thereafter, flip-arm 150 is vertical and horizontal slip on sliding part 160, and three bent axles 10 on it are transported on three first temporary positions 191 on bent axle slide unit 190. Bent axle 10 arrives behind three first temporary positions 191, and 190 horizontal slips of bent axle slide unit, transport bent axle 10 and arrive district undetermined, waits for that truss feed robot 200 receives.
Truss feed robot 200 upper three bent axles 10 on bent axle slide unit 190 are captured and on truss, carry out vertically, level transports, arrive centerless grinder 1 place and carry out the processing of first centreless grinding.
After first centreless grinding operation completes, the blanking crawl arm of truss blanking robot 300 moves in First centerless grinder 1, bent axle 10 is therefrom taken out and is slid on the second temporary position 331, and three bent axles 10 are temporary in due-in district 330. Certainly, the process requirements different according to bent axle 10, centreless grinding operation may need to carry out one to three time, if need carry out centreless grinding operation for the second time or for the third time, specialize in second truss feed robot 200 of second centerless grinder 1 and second truss blanking robot 300 the carrying step to bent axle 10 circulation first centreless grindings and carry out centreless grinding processing for the second time, the method for centreless grinding processing is for the third time identical with the method that centreless grinding is processed for the third time.
After last one centreless grinding operation completes, bent axle 10 is temporary 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. Between centerless grinder 1 and eccentric grinding machine 2, be provided with the first blanking supply line 400, a truss feed robot 100 that is responsible for centerless grinder 1 without sole duty captures three bent axles 10 be carried in the second conveyer chain 410 of the first blanking supply line 400, and in the second conveyer chain 410, V-type seat makes bent axle 10 fix and stablize and transport.
In the time that the first blanking supply line 400 transports approach the first six-DOF robot 500, full-time the first six-DOF robot 500 of doing in the eccentric grinder of the first step captures and is transported to full-time bent axle detent mechanism 800 places that do in the eccentric grinder of the first step by two bent axles 10 and carries out the work of eccentric location, then is transported in the eccentric grinding machine 2 of First and carries out eccentric grinder work. Because eccentric grinder order needs one or more eccentric grinding machine 2 to realize according to the different processing situation of bent axle 10, therefore be provided with First Transition supply line 550 between adjacent eccentric grinding machine 2, full-time the first six-DOF robot 500 in the eccentric grinding machine 2 of First is kept in and is transported being placed into First Transition supply line 550 after bent axle 10 is taken out from eccentric grinding machine 2, be transported to second eccentric grinding machine 2 place, the bent axle carrying operation that circulation as for the first time eccentric mill are consistent.
After last eccentric grinder order together, 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 full-time last eccentric grinding machine 2 simultaneously, bent axle is transported to thrust grinding machine 2 one sides by the second blanking supply line 600, captured by the second six-DOF robot 700 of full-time first step thrust surface grinder order.
The second six-DOF robot 700 is transported to two bent axles 10 simultaneously and in bent axle detent mechanism 800, carries out one by one bias location, after bent axle 10 is transported in thrust surface grinding machine 3, carries out thrust surface processing again, after first step thrust surface completion of processing, the second six-DOF robot 700 is placed in the second transition supply line 750 and keeps in and transport, rear continuation second step thrust surface grinds processing, and its carrying step is with reference to first step thrust surface carrying operation.
After final step thrust surface grinder order, the second six-DOF robot 700 of full-time last thrust surface grinding machine 3 takes out from thrust surface grinding machine 3 two bent axles 10, and is placed on discharging haul road, carries out bent axle 10 dischargings.
Finally it is emphasized that; the foregoing is only the preferred embodiments of the present invention; be not limited to the present invention; for a person skilled in the art; the present invention can have various variations and change, as variation of the increase of bent axle material stock unit upper position quantity, grinding machine group Internal abrasive machine value volume and range of product etc., within the spirit and principles in the present invention all; any amendment of making, be equal to replacement, improvement etc., within protection scope of the present invention all should be included in.
