Detailed description of the invention
Be described in detail to characteristic sum principle of the present utility model below in conjunction with accompanying drawing, illustrated embodiment, only for explaining the utility model, not limits protection domain of the present utility model with this.
As shown in Figure 1, shown in Figure 5, the utility model comprises the roller-way transmitted for wheel hub, and roller-way realizes the automatic transport of wheel hub.
Be provided with wheel hub wheel-type automatic identification equipment at roller-way gating location, the wheel hub wheel-type entering roller-way can be detected, and wheel hub wheel-type information is sent to controller.Corresponding hub parameter is called according to the hub type section straightening that the photograph identification of charging aperture judges.
Mobile manipulator 1, the wheel hub on roller-way can be carried to automatic section straightening by mobile manipulator, and coordinate roller-way to achieve automatically orthopedic, automaticity improves.Automatic section straightening is that roller bed through type is installed, and automatic section straightening is divided into three stations, is respectively the first station 2, second station 3 and the 3rd station 4.As shown in Figure 2 and Figure 3, the first station place is provided with the centering location that centralising device realizes wheel hub, and corresponding with centralising device is provided with photographing device 9 above wheel hub.Wherein said centralising device comprises four clamping rub wheels 5 that clamping cylinder 6 drives, four clamping rub wheels can along horizontally disposed guide rail placed in the middle 8 simultaneously to close/move away from four clamping rub wheel central square, also comprise the rotating shaft under rotating servo motor 7 drive, rotating shaft can drive the wheel hub at centralising device place to rotate.When wheel hub enters into the first station, wheel hub steps up by centralising device, by the position of photograph location determination hub stud holes on axis, now placed in the middle rotate stop waiting for mobile manipulator clamping after clamping placed in the middle open, mobile manipulator moves ahead, and wheel hub is sent into the second station.As shown in Figure 4, second station comprises orthopedic oil cylinder and lower orthopedic oil cylinder, wherein go up orthopedic oil cylinder and comprise one-level master cylinder 10 and secondary master cylinder 11, one-level master cylinder is connected 12 with upper servo slide block, upper servo slide block and orthopedic, 13 are fixedly connected with, and upper servo slide block can move up and down along the lead 14 vertically placed; Secondary master cylinder is fixed on servo slide block, and secondary master cylinder is connected with upper orthopedic appliance.The top of lower orthopedic oil cylinder 21 is fixedly connected with lower orthopedic platen, and lower orthopedic backing plate 22 is fixed in frame.Upper servo slide block goes downwards to assigned address according to hub parameter under the effect of one-level master cylinder, one-level master cylinder is connected to pressure sensor simultaneously, upper servo slide block two side joint displacement transducer, when there being one to reach setting value in two sensors, upper servo slide block stops action.Lower orthopedic backing plate is coordinated to realize, to the rectification of wheel hub plane of outer ring distortion, making the flatness of wheel hub outer ring reach ± 0.2mm (millimeter).As shown in Figure 6, Figure 7, described upper orthopedic appliance comprises the compression central shaft 15 be connected with secondary master cylinder, the bottom compressing central shaft is equipped with fairlead 16, fairlead to be nested with in guide type shoe 20, and compression central shaft bottom end is coniform, this coniform end is connected with the coniform groove fit of slider top, and slider bottom is also fixed with some push rods 18, push rod is identical with hub stud holes arrangement, and slide block is also provided with horizontal back-moving spring 19.Because wheel hub upper flange surface does not allow to collide with, so be connected with bolt hole automatic regulating apparatus in the two-level oil cylinder of upper end, this device automatically adjusts to bolt hole position (this position can be removed in following process process) according to hub parameter, reaches the object in orthopedic wheel hub wheel rim face by pressing this position.Because needing protection outside wheelboss flange face during orthopedic wheelboss flange face, so adopt bottom pressing bolt hole, because the bolt hole position of various wheel hub is different, the method for synchronization that this device adopts displacement controlled.
Secondary master cylinder and lower orthopedic oil cylinder are all connected with pressure sensor and displacement transducer.When there being one to reach setting value in two sensors, keeping 5 ~ 10 seconds, having reached orthopedic object, after this each oil cylinder Aligning control.
For ensureing that push rod can be pressed in bolt hole, have employed the mode of location of taking a picture when wheel hub enters forcing press.
3rd station comprises conveying robot, and the wheel hub after orthopedic to be carried on roller-way by the discharging of roller-way discharging opening by conveying robot, circulates thus.
Further, the end face of upper servo slide block and the top surface being parallel of lower orthopedic backing plate, ensure the orthopedic precision of precision of wheel hub plane of outer ring degree.For ensureing the depth of parallelism of top shoe and lower bolster, lower bolster adopts adjustable mounting means.Be convenient to dismounting and revise.
Above-described embodiment is only the description carried out preferred embodiment of the present utility model; not scope of the present invention is limited; under the prerequisite not departing from the utility model design spirit; relevant technical staff in the field, to various distortion of the present utility model and improvement, all should expand in the determined protection domain of the utility model claims.
