Description
Technical field
The utility model belongs to textile machinery part device field, especially relevant with a kind of two-chamber anti-vibration cylinder for yarn manufacture and collator winding device.
Background technique
The yarn cylinder of the manufacture of the yarn such as Spinning Machinery, two-for-one twister and collator in winding process due to broken yarn or yarn cylinder arrive prescribed level time, need timely for yarn cylinder lifting by the cone creel of winding device, when normal winding, need, by the cone creel of winding device, yarn cylinder is put down contact wind up roll.Existing winding device provides the throw-on pressure of yarn cylinder and wind up roll by a spring, and bobbin can vibrate unavoidably in package process, affects the forming quality of package, and long-time vibration also can cause damage to cone creel.
Model utility content
The purpose of this utility model is intended to overcome existing yarn take-up device affects package build quality and the problem causing cone creel to damage owing to can occur to vibrate in package process, provides a kind of yarn take-up device two-chamber anti-vibration cylinder that can reduce package vibration.
For this reason, the utility model is by the following technical solutions: a kind of yarn take-up device two-chamber anti-vibration cylinder, it is characterized in that, guide pin bushing assembly, floating piston, piston that described two-chamber anti-vibration cylinder comprises anti-vibration cylinder cylinder body, piston rod and from up to down sets gradually, the cylinder barrel that described anti-vibration cylinder cylinder body comprises upper end open and the cylinder cap mounted cover in cylinder barrel opening end, cylinder cap is provided with the sleeve part that gap is coated at cylinder barrel, and cylinder cap axially can move up and down along cylinder barrel under sleeve part guide and limit; Described guide pin bushing assembly is fixedly installed in inner cavity of cylinder, separate inner cavity of cylinder bottom guide pin bushing assembly and inner cavity of cylinder between form active chamber, guide pin bushing assembly is provided with pilot hole, piston-rod lower end enters the active chamber in inner cavity of cylinder through this pilot hole, upper end passes cylinder cap and interfixes with cylinder cap; Described floating piston movable set is in piston rod, and use seal ring packed-piston bar and floating piston, gap between floating piston and active chamber inwall, described active chamber is separated into the air cavity be positioned on the upside of floating piston and the oil pocket be positioned on the downside of floating piston, the oil in oil pocket is avoided to be exuded to outside anti-vibration oil cylinder, guide pin bushing assembly is provided with air hole and is communicated with air cavity and anti-vibration oil cylinder free surrounding space, in oil pocket, fill oil; Described piston is fixed on piston rod, oil pocket is separated into upper oil cavitie and lower oil cavitie, piston arranges master and unloads the through upper oil cavitie of oilhole and lower oil cavitie, piston is provided with has the main oil leak hole of flexible valve switch board component capping, valve switch board component is provided with and unloads the through secondary oilhole of oilhole with main, and secondary oilhole aperture is less than main oil leak hole.
During utility model works, piston rod is in the process moved up and down, piston is driven to move up and down in oil pocket, make the total volume of upper oil cavitie and lower oil cavitie can occur the change of volume due to moving up and down of piston rod, oil temperature change also can cause oil chamber volume to change, floating piston can slide up and down according to this Volume Changes, thus plays the effect compensating oil chamber volume change.In yarn winding process, the vibration of yarn cylinder drives piston rod to move up and down by a small margin by cone creel, the increase of yarn cylinder drives piston rod slightly to decline at a slow speed, upper oil cavitie and lower oil cavitie Volume Changes less, secondary oilhole is enough to meet the flowing of oil between upper oil cavitie and lower oil cavitie, because secondary oilhole aperture is less, can play certain inhibitory action to the flowing of oil, thus reduce the amplitude that moves up and down and the frequency of piston rod, play anti-vibration effect.When broken yarn and creeling joint, yarn cylinder needs to decline fast and touches by wind up roll, piston rod can fast significantly on move, upper oil cavitie rapid drop, oil pressure in upper oil cavitie increases fast, and the secondary oilhole on valve switch board component has little time the oil in upper oil cavitie to let out in lower oil cavitie, and pressure oil will wash valve switch board component open, the main oil leak hole of conducting, lets out lower oil cavitie by oil fast.
As to technique scheme supplement and perfect, the utility model also comprises following technical characteristics.
Described valve switch board component comprises valve switch plate and Returnning spring, and valve switch plate by arranging center mounting hole movable set in piston rod, and is covered in the aperture, lower end of the main oil leak hole of described piston, and described secondary oilhole is arranged on valve switch plate; Returnning spring is set in the part that piston rod is positioned at below valve switch plate, and between valve switch plate and the catch being fixed on piston rod, provides point restoring force providing the main oil leak hole of valve switch sheet reset capping.
Described valve switch plate middle bent epirelief, bottom surface forms the spring-housing groove of fovea superior, described Returnning spring is placed in this spring-housing groove, in the middle part of described piston bottom end, upwards indent forms the groove coordinating and hold epirelief part in the middle part of described valve switch, reduces piston rod evagination in the length of the part of described piston.
Between described piston and described oil pocket inwall, y-type seal ring is set, the space between packed-piston and oil pocket inwall.
Be provided with spring between described cylinder cap and guide pin bushing assembly, spring housing is loaded on piston rod, can produce elastic force by Compress Spring when piston rod moves down, and provides auxiliary force for yarn cylinder presses down to touch by wind up roll.
Described guide pin bushing assembly comprises guide pin bushing and guide pin bushing seat, and guide pin bushing seat is fixedly installed in inner cavity of cylinder, guide pin bushing seat is arranged central through bore and described air hole, and guide pin bushing is provided with described pilot hole and is fixed in the central through bore of guide pin bushing seat.Guide pin bushing assembly plays leading role to piston rod on the one hand, is to prevent the unexpected oil be seeped into inside air cavity from going to outside anti-vibration oil cylinder on the other hand.
Use the utility model can reach following beneficial effect: the utility model have employed the dual-chamber structure that active chamber is separated into air cavity and oil pocket by floating piston, the change of anti-vibration cylinder interior oil chamber volume can be compensate for, avoid inside and outside and produce pressure reduction, ensure that anti-vibration oil cylinder can normally use not lose efficacy, and the oil in oil pocket can be avoided to be exuded to outside anti-vibration oil cylinder; By guiding and the separation of guide pin bushing assembly, piston rod runs more steady, even if the oil in oil pocket is exuded to active chamber, also can be intercepted by guide pin bushing assembly and can not be exuded to outside anti-vibration oil cylinder in air cavity.
