Abstract
The utility model discloses a shedding link mechanism link mechanism, and belongs to the field of weaving machine harness frame transmission mechanisms. The existing shedding link mechanism has the defects that the support is not stable, the operation stressing is large, and the vibration and transformation are easily caused. The shedding link mechanism provided by the utility model comprises a short connecting rod driven by a cam swinging arm and a shedding link mechanism for connecting the short connecting rod and a harness frame, wherein the link mechanism comprises multiple vertical connecting rods which are arranged on the top of the harness frame and are parallel; the vertical connecting rods are spaced at equal intervals, the two ends of the vertical connecting rods are respectively connected with shedding pieces and the harness frame, and the short connecting rod is connected with the shedding pieces at one side of any end part of the harness frame; and the other shedding pieces are connected to the same horizontal connecting rod, the horizontal connecting rod is connected with the two vertical connecting rods, and a long connecting rod is connected between the horizontal connecting rod and one side of the end part of the harness frame. Through setting the multiple vertical connecting rods, the support to the harness frame is more stable, the external force is generated when the harness frame operates is obviously reduced, the stress is prevented from being concentrate on one position of the harness frame, and the vibration and transformation are not easy to generate.
Description
Technical field
The utility model belongs to harness frame in aweaving machine transmission mechanism field, and is especially relevant with a kind of shedding linkage.
Background technology
As shown in Figure 1, shedding linkage on existing Looms, comprise the short connecting rod and the shedding linkage that is connected short connecting rod and heald frame that are driven by cam swing arm, described shedding linkage is comprised of with the connecting rod that is connected two shedding sheets the vertical connecting rod that is fixed on the heald frame two ends, the shedding sheet that is connected on vertical connecting rod, and wherein a shedding sheet is connected with cam swing arm by short connecting rod.During use, cam swing arm swings by default cam curve law, drives the shedding connecting rod mechanism movement by short connecting rod, makes heald frame do the upper and lower opening motion.In the integrated box movement process, warp thread to the active force of heald frame all the time with the integrated box movement opposite direction.Connect to support by vertical connecting rod due to heald frame two ends and be subjected to the masterpiece elevating movement, heald frame is yielding under the acting in conjunction of warp thread and vertical connecting rod, causes the opening of warp thread fell unintelligible, produces wrong flower; The suffered external force of heald frame and acceleration are excessive, and for avoiding producing the greater impact vibration, the speed of a motor vehicle can only reach 200-300 rev/min.When heald frame up moves, the heald frame force analysis as shown in Figures 2 and 3, position, intermediate portion Moment is maximum, after the long-time continuous motion, heald frame middle part fatiguability fracture.
The utility model content
It is unstable that the purpose of this utility model is intended to overcome the integrated box movement that has the shedding linkage now, easily produce the defective of vibration and distortion, provide a kind of heald frame to support more firm, during work, suffered external force is less, and is difficult for producing the shedding linkage of vibration and distortion.
for this reason, the utility model is by the following technical solutions: a kind of shedding linkage, comprise the short connecting rod and the shedding linkage that is connected short connecting rod and heald frame that are driven by cam swing arm, it is characterized in that, described linkage comprises and is located at a plurality of vertical connecting rods that the heald frame top is parallel to each other, the vertical connecting rod equi-spaced apart, the vertical connecting rod two ends are connected with heald frame with the shedding sheet respectively, short connecting rod is connected with the shedding sheet of heald frame arbitrary end one side, all the other shedding sheets are connected on same tranverse connecting rod, be connected with two vertical connecting rods on tranverse connecting rod, be connected with long connecting rod between the shedding sheet of described tranverse connecting rod and heald frame end one side.By a plurality of vertical connecting rods are set, heald frame is supported more firm, during heald frame work, suffered external force significantly reduces, and avoids stress to concentrate on heald frame a certain position, and is difficult for producing vibration and distortion.Use the loom speed of a motor vehicle of this linkage and can bring up to 200-500 rev/min.Wherein, cam swing arm moves through the usual manner realization.
Use the utility model can reach following beneficial effect: by changing shedding linkage structure, a plurality of vertical connecting rods to be set on heald frame, to drive simultaneously heald frame work, move more stable, than existing shedding linkage, heald frame when work be stressed significantly to be reduced, and is difficult for producing vibration and distortion.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail.
as Fig. 4 ~ shown in Figure 6, but the utility model comprises the heald frame 3 of oscilaltion campaign, the short connecting rod 2 that cam swing arm 1 drives, be connected with the shedding linkage between described heald frame and short connecting rod, described linkage comprises that three are located at the vertical connecting rod 4 that the heald frame top is parallel to each other, each vertical connecting rod equi-spaced apart, are connected with heald frame with shedding sheet 5 respectively and are connected in the vertical connecting rod two ends, short connecting rod 2 is connected with the shedding sheet of heald frame right-hand member, all the other two shedding sheets are connected on same tranverse connecting rod 6, be connected with two vertical connecting rods on tranverse connecting rod, the shedding sheet of described heald frame right-hand member and being adjacent is provided with long connecting rod 7 and is connected between the shedding sheet.During heald frame work, cam swing arm is according to default orbiting motion, the shedding sheet that short connecting rod drives the heald frame right-hand member thereupon moves up and down together, be connected to the adjacent shedding sheet of long connecting rod drive on this shedding sheet, interlock by tranverse connecting rod moves another two shedding sheets together, under the acting in conjunction of three shedding sheets, lift or put down heald frame by the vertical connecting rod that is attached thereto, realize the heald frame lifting work.Force analysis is as shown in Fig. 5,6, and heald frame is stressed everywhere all obviously to be reduced, and maximum moment also reduces thereupon, no longer is positioned at the heald frame centre position, also indefatigability fracture after long-play; Heald frame drives lifting by three vertical connecting rods, and is not yielding, moves up and down more stable.
