Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
With reference to Fig. 1, a kind of erecting by overhang realizing long distance and move without frictional plane, comprise supporting part, follow-up unit, linear rail system and detection part, wherein supporting part is made up of frame member 1 of hanging oneself, lower suspension bracket part 6, four suspension rods 3, two pieces of transverse sliders 2, pair of guide rods seat 4, longitudinal air-bearing shafts 12.Air supporting follow-up unit is made up of longitudinal air supporting cover 5, horizontal air-bearing shafts 8, horizontal air supporting cover 11, air supporting seat 7, the round floating cushion 10 of 9, four pieces, air supporting support.Detection device is made up of the permanent magnet of horizontal longitudinal laser displacement sensor and the light barrier of correspondence, two pairs of Hall transducers and correspondence.
Described frame member 1 of the hanging oneself slide block 2 parallel with two pieces connects, described frame member 1 of hanging oneself is connected with lower suspension bracket part 6 by four suspension rods 3, described guide rod seat 4 is arranged on the platform of lower suspension bracket part 6, described longitudinal air-bearing shafts 12 vertical equity to be fixed on guide rod seat 4, described longitudinal air supporting cover 5 is sleeved on longitudinal air-bearing shafts 12, air supporting seat 7 and horizontal air supporting overlap 11, longitudinal air supporting cover 5 is tightly connected, described horizontal air supporting cover 11 is sleeved on horizontal air-bearing shafts 8, described horizontal air-bearing shafts 8 two ends and air supporting support 9 are fixed, described air supporting support is cross-type, described four round floating cushions 10 are arranged on four angles of air supporting support.Described horizontal laser displacement sensor and longitudinal laser displacement sensor are arranged on lower suspension bracket, and corresponding light barrier is arranged on air supporting support, can the horizontal relative displacement vertically moved of Measurement accuracy air supporting support by laser reflection.Described Hall transducer is arranged on lower suspension bracket, and induced magnet is arranged on corresponding air supporting support.
The basic fundamental thinking that plane motion air-floating apparatus adopts is:
By supporting part, air-floating apparatus is fixed on the below of cross slide way slide unit, can move with slide unit, the follow-up unit of plane motion air-floating apparatus can do and move without frictional plane on air supporting seat, namely longitudinal air supporting cover can frictionless motion along the longitudinal, horizontal air-bearing shafts can along horizontal frictionless motion, by air supporting seat, horizontal air supporting cover and longitudinal air supporting cover, spatially in 90 °, will drive horizontal air-floating apparatus servo-actuated together when longitudinal air supporting cover motion.Horizontal air-bearing shafts two ends are connected with criss-cross air supporting support, and air supporting support four pin are all provided with circular floating cushion, and floating cushion is parallel with lower suspender member, such air supporting support can in the plane of lower suspender member frictionless motion.Because air-bearing processing request is high, bearing capacity is little, by the design of air supporting support, adds the intensity of carrying.
Air-floating apparatus is by air supporting seat air feed, and flexible tracheae connects air supporting seat suction port, and air supporting seat inside is cavity, can connect horizontal and vertical air supporting cover suction port.Stretch tracheae and lower suspension bracket of air inlet is fixed, and can move with slide block transversal stretching, resupply air supporting seat, due to flexible tracheae light weight, stretchability is good, servo-actuated apart from short, and when thus air supporting seat moves vertically, the disturbing influence that tracheae produces is very little.
Laser displacement sensor and Hall transducer are all equipped with in vertical and horizontal direction, laser displacement sensor can measure the relative displacement of horizontal air-bearing shafts, the motion of longitudinal air supporting cover, by signal feed back to guide track system, moved by Serve Motor Control guide rail slide block, ensure air-floating apparatus follow-up unit frictionless motion within the scope of its short stroke all the time, virtually extend passive scope of following.Hall transducer plays position limitation protection effect; when displacement transducer in movement process or miscellaneous part produce fault; laterally longitudinal air-floating apparatus athletic meeting oversteps the extreme limit stroke; cause damage; thus guide track system is fed back signal to by Hall transducer; the motion of restriction original direction, plays the effect of protection.
Cross slide way can move along horizontal linear module, and laterally novel module is arranged on cross slide way crossbeam, and the two ends of cross slide way crossbeam are fixed on the slide block of longitudinal rail, and longitudinal rail slide block can guide rail movement along the longitudinal.Horizontal and vertical actuating motor is by the motion of band wheel drive guide rail slide block, and servo longitudinal motor moves with longitudinal sliding block.Horizontal and vertical guide rail all has its sensing system and control system, in solar wing spreading process, the displacement signal of coming is fed back according to plane motion air-floating apparatus, accurate control slide block moves corresponding distance, when ensureing that guide is moved all the time within the scope of air-float guide rail, thus realize the plane motion of long distance frictionless.
Effect of the present invention and advantage are:
Air-float guide rail and floating cushion cooperatively interact, and add the bearing capacity of erecting by overhang; Guide track system is initiatively followed, and cooperatively interact with plane motion air-floating apparatus, be exaggerated tracking error, virtual the passive of air-float supporting device that extend follows stroke; Laser displacement sensor can accurately be measured the stroke of air-floating apparatus and feed back to guide track system, and by the calculating of velocity of displacement acceleration, initiatively system for tracking reliability is high; Installed Hall transducer, played a protective role, safety coefficient is high; Plane motion air-floating apparatus is without the impact of electric wire disturbing force.
