Detailed Description

The principles and features of the present invention will be described with reference to the drawings, which are provided for illustration only and are not intended to limit the scope of the invention.

As shown in fig. 1-5, the embodiment of the utility model provides an automatic line printer positioning mechanism, including two curb plates 2, two curb plates 2 are opposite vertical settings on first mounting panel 1, two 2 outsides of curb plate are provided with stop gear 3, stop gear 3 includes fixed plate 31, location cylinder 32 and locating pin 33, fixed plate 31 one end is fixed on 2 lateral surfaces of curb plate, fixed mounting has location cylinder 32 on the fixed plate 31, the flexible end fixedly connected with locating pin 33 of location cylinder 32, the one end that locating pin 33 keeps away from location cylinder 32 runs through curb plate 2, it is provided with two pivots 4 and two pivots 4 are located same horizontal plane to rotate between two 2 inboards, two 4 both ends of pivot respectively are provided with a sprocket 5, two sprockets 5 of homonymy pass through the meshing of chain 6 and connect, pinhole 61 has been seted up to one side that two chains 6 are close to curb plate 2, pinhole 61 and locating pin 33 adaptation.

The method comprises the following steps that a plurality of line body carriers needing positioning and scribing are horizontally arranged between opposite surfaces of two chains 6 at intervals, line bodies needing scribing are added on the line body carriers, a rotating shaft 4 is rotated, the carriers rotate along with the chains 6, when pin holes 61 in the chains 6 rotate to the positions corresponding to limiting mechanisms 3, positioning cylinders 32 on a fixing plate 31 are started, positioning pins 33 are pushed to be inserted into the pin holes 61 in the chains, at the moment, the chain 6, a chain wheel 5 and the rotating shaft cannot rotate due to the fact that the positioning pins 33 are clamped in the pin holes 61, and therefore accurate positioning of the line body carriers is achieved; the fixed setting of curb plate 2 can make curb plate 2 stable on first mounting panel 1 to ensure that positioning mechanism is more steady at the in-process of operation.

Embodiment 2 an automatic line printer positioning mechanism, on embodiment 1's basis, one of two pivot 4 is the driving shaft, and another is the driven shaft, and the diaxon is located the both ends of curb plate 2 respectively, and in the concrete implementation, exert power to the driving shaft, can reach driving shaft and driven shaft synchronous operation through the transmission of sprocket 5 and chain 6, avoid unnecessary power loss, the diaxon makes the length of chain 6 longer far apart, can add more line body carriers between two chains 6, improves work efficiency.

Embodiment 3 an automatic line printer positioning mechanism, on the basis of embodiment 1 or 2, still include actuating mechanism 7, actuating mechanism 7 includes second mounting panel 71, driving motor 72, spur gear 73 and overload gear 74, and the one end that the driving shaft of two pivots 4 is located the curb plate 2 outside is fixed with overload gear 74, and driving motor 72 passes through second mounting panel 71 fixed mounting in the curb plate 2 outside, and driving motor 72 passes through spur gear 73 and overload gear 74 meshing to be connected with the driving shaft transmission.

Start driving motor 72, the meshing through overload gear 74 and spur gear 73 drives pivot 4 and rotates, when locating pin 33 inserts in pinhole 61, driving motor 72 continues the operation, the external tooth of overload gear 74 transships the rotation this moment, but can not drive pivot 4 and rotate, when locating pin 33 takes out pinhole 61, overload gear 74 is under the effect of spur gear 73, continue to make pivot 4 begin to rotate, in the concrete implementation, can make driving motor 72 continue the operation through the overload nature of overload gear 74, need not control to open and stop, can avoid opening and stop the energy loss that brings, also can avoid positioning mechanism to transship and break down.
