A kind of chain type positioning cycle mechanism
The utility model relates to automation equipment field, refers in particular to a kind of chain type positioning cycle mechanism.
In manufacture production and processing, automated production degree is more and more higher, is substantially all to carry out Detroit automation by automation equipment, impact between upper and lower operation is very large, if last process produces deviation, the equipment of next procedure cannot normally work, therefore high to the precise requirements of every procedure.
In the manufacturing, it is the most common that belt conveyor carrys out conveying work pieces as carrier, cylinder or common electric machine is mostly adopted to drag belt conveyor at present, because cylinder and common motor do not have speed reduction gearing, the workpiece on belt conveyor is caused to stop unstable, part workpiece cannot rest on designated area, and large to the rigid shock of belt conveyor, and next procedure cannot normal operation.In relay production field, degree of automation is high, without the need to attention of staff, if relay workpiece accurately cannot reach assigned address, by Severe blockage whole production line, will bring massive losses to enterprise.
Utility model content
In order to solve the problem, the utility model is to provide a kind of chain type positioning cycle mechanism, adopts servomotor dragging transmission chain to realize the cyclic transfer of workpiece, rational in infrastructure compact, is applicable to applying in automation equipment.
Technical scheme provided by the utility model is: a kind of chain type positioning cycle mechanism, the utility model comprises endless drive chain and transmits road, described endless drive chain is erected at and transmits on road, endless drive chain is provided with frock carrier, frock carrier is for carrying workpiece, transmit road to be supported by 4 L-type support, transmit rear and front end, road and be respectively equipped with sprocket for main drive and from driving chain wheel, sprocket for main drive is located between support by drive shaft mount, be located between tensioning plate from driving chain wheel by drive shaft mount, L-type support described in one of them is fixed with servomotor and retarder, described driven by servomotor sprocket for main drive.
Described transmission road is a U-type groove.
Described U-type groove width is suitable with endless drive chain width.
Described frock carrier is a rectangular recess, and groove is used for place work piece, and frock carrier is screwed on endless drive chain.
Described screw number is 6.
Advantage of the present utility model is: compact conformation, volume is little, processing is simple, relatively use in automation equipment, this chain type positioning cycle mechanism adopts servomotor to drag, and workpiece off-position is accurate, is provided with retarder, endless drive chain starts and stops to produce rigid shock, and the transmission road with U-type groove more steadily transmits by workpiece.

Detailed description of the invention
Illustrate that the utility model is described in further detail with specific embodiment below in conjunction with accompanying drawing.
As shown in the figure, a kind of chain type positioning cycle mechanism, comprise endless drive chain 1 and transmit road 2, endless drive chain 1 is erected at and transmits on road 2, endless drive chain 1 is provided with frock carrier 3, frock carrier 3 is for carrying workpiece, transmit road 2 to be supported by 4 L-type support 5, L-type support 5 is provided with tapped bore 6, for being fixed in the middle of automation equipment, transmit rear and front end, road 2 and be respectively equipped with sprocket for main drive 7 and from driving chain wheel 8, sprocket for main drive 7 is erected between L-type support 5 by transmission shaft 10, be erected between tensioning plate 9 from driving chain wheel 8 by transmission shaft 10.L-type support 5 described in one of them is fixed with servomotor 11 and retarder 4, servomotor 11 drives sprocket for main drive 7 to do cyclic rotation.Described transmission road 2 is a U-type groove, and U-type groove width is suitable with endless drive chain 1 width, endless drive chain 1 is run more steady.Described frock carrier 3 is a rectangular recess 31, and groove 31 is for place work piece, and ensure that workpiece can not produce skew in transport process, frock carrier 3 is fixed on endless drive chain 1 by 6 screws 32, and the number of frock carrier 3 is 15.
During concrete use, by manipulator or miscellaneous equipment, workpiece is placed on Workpiece carrier 3, starts according to control program servomotor 11, servomotor 11 drives sprocket for main drive 7 to rotate, sprocket for main drive 7 is driven by endless drive chain 1 and rotates from driving chain wheel 8, workpiece moves with endless drive chain 1 in Workpiece carrier 3, and after moving into place, servomotor 11 cuts out, under the effect of retarder 4, sprocket for main drive 7 slowly stops operating, and manipulator takes out workpiece subsequently, completes single job.
