Detailed description of the invention
Embodiment 1
With reference to Fig. 1,2,3, present embodiments provide a kind of driving mechanism of jacquard lifting knives, swing arm 2 is fixed on arm shaft 1, be positioned in swing arm 2 and offer a transverse joint elongated hole 5, one end is arranged in transverse joint elongated hole 5 place with the rod head 3 of mount hole 12 by joint bearing 4, joint bearing 4 utilizes clamping element to be fixed in swing arm 2, and wherein clamping element comprises pinching screw 13, clamp shaft pressure cap 14, clamping bearing 15, clamping pull bar bearing pin 16, clamping inner washer 17, clamps little transparent cover 18, clamping bullet pad 19 and binding nut 20.Belong to hanging-connecting between rod head 3 and joint bearing 4 hinged, rod head 3 can along the axis swing of joint bearing 4.By regulating the degree of tightness of clamping element, realizing joint bearing 4 and locating transverse joint elongated hole 5 sky and do not exist together.
Be positioned in swing arm 2 and offer a longitudinal rod through hole 6, this longitudinal rod through hole 6 is communicated with transverse joint elongated hole 5, forms T-type structure.
This driving mechanism also comprises a joint bearing 4 regulating mechanisms, comprise adjusting screw(rod) 7 and described adjusting rod is fixed on the adjusting rod fixture in swing arm 2, this adjusting screw(rod) 7 is provided with external screw thread, can just in time match with the through bar screw 8 be opened on joint bearing 4.Adjusting screw(rod) 7 can be overall through joint bearing 4, and by turn adjusting screw(rod) 7, regulate the position of joint bearing 4.
Above-mentioned adjusting rod fixture comprises one with the pressing plate 9 of fixing rod aperture 10, adjusting screw(rod) 7 is provided with the positioning table 11 that a diameter is all greater than longitudinal rod through hole 6 aperture and fixing rod aperture 10 aperture, by pressing plate 9 fixing in swing arm 2, positioning table 11 is clamped, thus reaches the object of secured adjusted screw rod 7.
When needing to finely tune the position of rod head 3, first loosen clamping element, make joint bearing 4 be in half dummy status, then use spanner turn adjusting screw(rod) 7, after adjusting the position of joint bearing 4, screw down clips gripping members can complete whole trimming movement.
The driving mechanism of the jacquard lifting knives of the present embodiment, fine setting operation is very convenient, and simultaneously joint bearing 4 is in all strong support of vertical and horizontal, when arm shaft 1 drives swing arm 2 to swing, joint bearing 4 can not because of centrifugal force sideslip; The displacement of whole trim process center tap bearing 4 is steady, there is not situation about trembleing back and forth; Owing to passing through threaded adjusting position, the final location therefore for physical location is grasped very well.
Embodiment 2
With reference to Fig. 4, the present embodiment general configuration is similar to Example 1, difference is that longitudinal rod through hole is with internal thread, adjusting rod is with the external screw thread matched with longitudinal rod through hole internal thread, be positioned on adjusting rod and offer horizontal fixed via, joint bearing is located on adjusting rod by horizontal fixed via.
The position of adjusting rod is adjusted and is realized by the screw thread between adjusting rod and longitudinal rod through hole, and adjusting rod and joint bearing are only the common structures that wears, and its advantage mainly contains following 2 points:
1, be more convenient for modular repair dismounting, reduce precision component damage possibility.
2, joint bearing is in situations such as operational vibration, and occurs between adjusting rod laterally slightly to slide, and therefore can not apply cross force to adjusting rod, guarantee each parts long term reliability.
