Abstract
The utility model relates to a stable motion device of a heald frame. The heald frame comprises two cross rods and two vertical rods. The stable motion device of the heald frame is characterized by comprising two pairs of fixing guide plates which respectively extend longitudinally and arranged at two ends of the heald frame, and each pair of the fixing guide plates are arranged at two sides of the vertical rods at corresponding ends of the heald frame. The stable motion device of the heald frame limits the guide plates to generate overlarge excursion along the transversal direction, and reduces bad scurry of the heald frame along the longitudinal direction through appropriate friction force during contact between the friction force heald frame and the guide plates, and accordingly warp is protected. Fixing plates fixed on the guide plates can be arranged above the heald frame, the fixing plates and the heald frame are connected through a spring, and accordingly functions of buffering and stabilizing the heald frame are played. Elastic buffering layers can further be arranged on the inner sides of the guide plates so as to protect lateral faces of the heald frame and avoid abrasion.
Description
Technical field
The utility model relates to a kind of stopping means, relates in particular to a kind of device of stable air-jet loom heald frame motion.
Background technology
Heald frame mainly plays driving the effect that warp thread forms opening as one of significant components of air-jet loom, and the heald frame of shuttleless loom adopts aluminium matter alloy more.When heald frame moves up and down, only the upper end is fixedly linked with drive unit, and after two findings of the common employing of the clamping device of heald frame cross one another and connect, be installed in again on the support of frame, this connected mode built on the sand, up and down play easily occuring, and then cause distortion, the fracture of warp thread, affects textile quality.
Summary of the invention
The utility model has overcome the deficiencies in the prior art, provides a kind of simple in structure, spacingly is combined the stable motion device of the heald frame that stablizing effect is good with cushioning effect.
For achieving the above object, the technical solution adopted in the utility model is: a kind of stable motion device of heald frame, described heald frame comprises two cross bars and two vertical poles, it is characterized in that: comprise that longitudinal extension respectively is positioned at two pairs of resting guides at described heald frame two ends, every a pair of described resting guide is located at the both sides of heald frame respective end vertical pole.
In preferred embodiment of the utility model, further comprise comprising that also at least two upper ends fix, the spring on described heald frame top is located in the lower end.
In preferred embodiment of the utility model, comprise that further the width of described guide plate is greater than the width of heald frame corresponding end vertical pole.
In preferred embodiment of the utility model, comprise that further laterally extending fixed head is fixed in the upper end of described spring, the two ends of described fixed head are individually fixed on two pairs of described guide plates, and the two ends of fixed head are respectively equipped with inside arc notch.
In preferred embodiment of the utility model, comprise that further the inboard of described guide plate is provided with elastic cord breaker.
In preferred embodiment of the utility model, comprise that further length that described guide plate stretches out is greater than 1/2 of described heald frame vertical pole length, less than heald frame vertical pole total length downwards.
The utility model has solved the defective that exists in the background technology; the stable motion device restriction guide plate of heald frame of the present utility model is laterally producing excessive skew; and suitable frictional force weakens longitudinally bad play of heald frame when contacting with guide plate by heald frame, with the protection warp thread.The fixed head that is fixed in guide plate can be set above heald frame, link to each other with spring between fixed head and the heald frame, play the effect of buffering and stable integrated box movement.Can also elastic cord breaker be set in the guide plate inboard, wearing and tearing are avoided in protection heald frame side.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the schematic diagram that preferred embodiment of the present utility model is installed on the heald frame top;
Fig. 2 is the top view of Fig. 1;
Among the figure: 1, cross bar, 2, resting guide, 3, vertical pole, 4, fixed head, 41, the arc notch, 6, spring.
The specific embodiment
In conjunction with the accompanying drawings and embodiments the utility model is described in further detail now, these accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Shown in Fig. 1-2, the stable motion device of a kind of heald frame of the present utility model, heald frame comprise two cross bars 1 and two vertical poles 3.The stable motion device of heald frame comprises that longitudinal extension respectively is positioned at two pairs of resting guides at heald frame two ends, the fixed head 4 of laterally extending connection heald frame two ends resting guide, and be located at spring 6 between fixed head and the heald frame top.Every a pair of resting guide is located at the both sides of heald frame respective end vertical pole 3.Two resting guides 2 of every a pair of resting guide are parallel to each other and be parallel to the heald frame plane, and the width of two resting guides 2 is identical, greater than the width of heald frame corresponding end vertical pole 3, and the every equal in length that resting guide 2 stretches out vertical pole 3 along width two directions.The quantity of spring 6 is at least two, is preferably 5, and fixed head 4 bottoms are fixed in upper end separately, and the heald frame top is fixed in the lower end, and the orientation of each spring 6 is along the bearing of trend of cross bar 1.Every end of fixed head 4 is individually fixed on a pair of resting guide of corresponding end, and is provided with laterally inwardly the arc notch 41 of depression, arc notch 41 symmetries at fixed head 4 two ends, and related fittings that can accommodating heald frame, for example clamping device passes through.The inboard of each resting guide 2 is provided with elastic cord breaker, and the distance of two elastic buffer interlayers on the every pair of resting guide 2 is greater than the thickness of the vertical pole 3 of heald frame.Elastic cord breaker can be rubber, perhaps foam.The length that each resting guide 2 stretches out downwards is greater than 1/2 of heald frame vertical pole 3 length, less than heald frame vertical pole 3 total lengths.
During work, heald frame moves up and down, two pairs of resting guides limit respectively the lateral shift of heald frame within the distance of every pair of two resting guides 2, the elastic cord breaker of resting guide 2 inboards reduces the damage that heald frame bump resting guide 2 causes on the one hand, on the other hand with and the frictional force of 3 of heald frame vertical poles suitably weaken vertically bad beating of heald frame.On the basis that the spring 6 on heald frame top obtains limiting in the lateral attitude of heald frame, suitable buffering is played in the lengthwise movement of heald frame, further stablize the Working motion of heald frame, improve the quality of weaving.
Above foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related personnel can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the specification, must determine technical scope according to the claim scope.
