The specific embodiment

Below in conjunction with a specific embodiment, the utility model is described in further detail:

Shown in accompanying drawing 1 to Fig. 3, the swing arm structure of a kind of reciprocally swinging transferring wall floor tile described in the present embodiment.It comprises swing arm unit 1, swing arm driving assembly 2, pedestal 4 and wall floor tile grip device 5.Swing arm unit 1 wherein comprises swing arm 101, swinging turntable 102 and the Timing Belt joint 103 and Timing Belt clamping plate 104 of both sides; Swing arm driving assembly 2 comprises Timing Belt drive wheel 202, Timing Belt track adjusting wheel 203 and the Timing Belt 204 of reducing motor 201, axle drive shaft 205, both sides; Pedestal 4 comprises and supports the axle 401 of swing arm unit 2 and bearing 402, supports one group of pivot shaft 404 of Timing Belt track adjusting wheel 203, the bearing seat 405 of supporting driving shaft 205 and the fixedly permanent seat 403 of reducing motor 201.

A pair of swing arm 101 and a pair of swinging turntable 102 lay respectively at the both sides of oscillating arm mechanisms, and wherein the centripetal end of swing arm 101 is fixed on the swinging turntable 102 of homonymy, and the other end is connected with wall floor tile grip device 5, for grasping transferring wall floor tile.Swinging turntable 102 is supported on axle 401 by bearing 402, can flexible rotating.

Swinging turntable 102 described in this example is for being with imperfect wheel disc jaggy, in the outside of its remaining face of cylinder 102-1, arranging Timing Belt track adjusting wheel 203 and Timing Belt drive wheel 202, and Timing Belt drive wheel 202 is greater than Timing Belt track adjusting wheel 203 apart from the width between centers of swinging turntable 102 apart from the width between centers of swinging turntable 102.Timing Belt 204 described in this example is open loop form, first make its interstitial segment---Timing Belt drive wheel 202---Timing Belt track adjusting wheel 203 of walking around successively Timing Belt track adjusting wheel 203 with S type path, then the remaining face of cylinder 102-1 that two ends are attaching swinging turntable 102 outflanks winding to indentation, there, and indentation, there by two groups of Timing Belt joints 103 and Timing Belt clamping plate 104 by Timing Belt 204 two ends respectively tensioning be fixed on the indentation, there of swinging turntable 102.

Reducing motor 201 drives Timing Belt drive wheel 202 reciprocating rotaries of both sides by axle drive shaft 205, by the traction of Timing Belt 204, drive swinging turntable 102 and swing arm 101 reciprocally swingings.Because the diameter of swinging turntable 102 face of cylinder 102-1 is several times as much as the pitch circle diameter of Timing Belt drive wheel 202, therefore Timing Belt drive wheel 202 rotates the servo-actuated angle that an angle produces on swinging turntable 102 and also the multiple with identical is dwindled, and avoids thus the positioning precision of swinging turntable 102 and swing arm 101 to be subject to the interference of the working clearance formed free rotation space on Timing Belt drive wheel 202 between reducing motor 201 rotors.Meanwhile, owing between Timing Belt drive wheel 202 and swinging turntable 102 being 204 transmissions of employing Timing Belt, the gapless driving feature of utilizing Timing Belt 204 to have, the interference of effectively having avoided producing new free rotation space in this transmission process.In addition, the flexibility having due to Timing Belt can absorb the impact load that alleviation swing arm unit 1 brings swing arm driving assembly 2 in fast reciprocating swing process, makes oscillating arm mechanisms work more steadily reliable, the longer service life of equipment.

This oscillating arm mechanisms also includes the cylinder power-assisted assembly 3 that is positioned at oscillating arm mechanisms both sides, the eccentric weight moment producing in swing process for the total centre of gravity of balance oscillating arm assembly 1 and wall floor tile grip device 5.This cylinder power-assisted assembly 3 comprises cylinder 301 and pipe link 302.Wherein, the afterbody of cylinder 301 and pedestal 4 are hinged, and piston rod and pipe link 302 are fixedly linked.Specific radius at swinging turntable 102 is provided with hinged seat 105 for the bar 302 that is articulated and connected.Cylinder 301 acts on a balancing torque by pipe link 302 and hinged seat 105 on swinging turntable 102, the eccentric weight moment that the total centre of gravity of balance oscillating arm assembly 1 and wall floor tile grip device 5 produces in swing process.By being that hinged seat 105 is selected suitable angle positions on swinging turntable 102, while making vertex that the total centre of gravity when swing arm unit 1 and wall floor tile grip device 5 moves, the maximum retraction state of cylinder 301 in its forced stroke.

Retraction direction weighing apparatus at cylinder 301 is pressed air feed, and the another side of piston keeps emptying, makes cylinder 301 keep stretching action power constantly.According to the product principle of moment: when the maximum retraction state of cylinder 301 in its forced stroke, the moment that its stretching action power forms on swinging turntable 102 equals zero, now, swing arm unit 1 is positioned at vertex with the total centre of gravity of wall floor tile grip device 5, eccentric weight moment equals zero, and does not need balancing torque; When the total centre of gravity of swing arm unit 1 and wall floor tile grip device 5 swings aside decline from vertex, eccentric weight moment occurs and strengthens gradually, meanwhile, hinged seat 105 on swinging turntable 102 is to opposite side beat, the stretching action power of cylinder 301 is synchronous on swinging turntable 102 to be produced opposing torque and also synchronously strengthens, and forms the reverse balancing torque that substantially keeps synchronization fluctuate with the eccentric weight moment of

swing arm unit

1 and 5 generations of wall floor tile grip device.The above-mentioned technical scheme of the eccentric weight moment that cylinder power-assisted assembly 3 balance oscillating arm assemblies 1 and wall floor tile grip device 5 produce in swing process of utilizing in oscillating arm mechanisms can effectively be alleviated the shock load that oscillating arm mechanisms produces swing arm driving assembly 2 in reciprocally swinging process, be conducive to improve hunting frequency, promote the work efficiency of oscillating arm mechanisms, extension device service life.

In sum, the oscillating arm mechanisms of this reciprocally swinging transferring wall floor tile is by the technical schemes such as eccentric weight moment that adopt Timing Belt traction swinging turntable and utilize cylinder power-assisted assembly balance oscillating arm mechanism to produce in swing process, the interference of the working clearance that can effectively avoid each drive disk assembly to swing arm positioning precision, alleviate the impact load that oscillating arm mechanisms produces in fast reciprocating swing process, make oscillating arm mechanisms motion steadily, reliable operation, and extend the service life of oscillating arm mechanisms, be worthy to be popularized.

The embodiment of the above is only the preferred embodiment of the utility model, not with this, limits practical range of the present utility model, therefore the variation that all shapes according to the utility model, principle are done all should be encompassed in protection domain of the present utility model.
