Description
Technical field
The utility model belongs to parts of textile machine, is specifically related to a kind of from the pneumatic pipe device of grabbing of aligning side position clamping.
Background technology
The pipe device of grabbing of fine spining machine integral cosine doffing device roughly is divided into two classes both at home and abroad at present: piston type, gasbag-type.The weak point that piston type is grabbed the pipe device is: it does not have the automatic aligning function, when grabbing pipe device Clamping Center when not overlapping with the spool center, as rigging error, foozle etc., grab pipe device piston clamping spool by force, make spool by spindle " not dead " and frictional force is increased sharply, the result makes that grabbing the pipe device can pull out any more spool, thereby cause the gas frame to walk or be out of shape, or cause spindle to damage, when the spool vary in diameter, grab the yet necessary corresponding replacing of pipe device, thereby its versatility is not strong; It is " pressure cylinder pipe " design that piston type is grabbed pipe device hat-shaped structure, and when being wound with too much residual yarn or meeting fortuitous event such as barrier on running into spindle, the spool that is held can only push away by force grabs pipe device cap.But in fact, when meeting accident, because last top power is very big, and direction is uncertain, grabs pipe device cap before being pushed away, and always forces the gas frame to walk earlier or is out of shape, and then cause the error of follow-through, perhaps causes the damage of vital parts such as spindle.
Device has possessed the structure of automatic aligning, the characteristics of highly versatile although gasbag-type is grabbed pipe, because airbag wall is working face, is again sealing surface, and wall is thin easy to wear, and then causes gas leakage and lost efficacy, and service life is short.The powder that weares and teares can pollute yarn.
In addition, existing grabs no matter the pipe device is piston type or gasbag-type, because of its structure, when grasping spool, all has to be inserted in from spool top, drop to the crawl position, thereby its stroke is long, has prolonged non-cutting time.
Summary of the invention
Technical problem to be solved in the utility model provides that a kind of it has the characteristics of automatic aligning from the pneumatic pipe device of grabbing of aligning side position clamping, can guarantee to grab the pipe action accurately, stable, reliable; The clamping of side position to be saving impulse stroke and non-cutting time, adaptive various spools, and versatility is good, long service life.
The technical solution of the utility model: a kind of from the pneumatic pipe device of grabbing of aligning side position clamping, it comprises first chela, second chela, elastomer, cylinder body, cylinder head, piston, elastic film, alignment pin, nut, upper bracket, lower carriage, bearing pin, sealing gasket dextrorotation spring, left-handed spring, first screw, gentle of second screw, the front end of first chela and second chela is elastomer of setting-in respectively, the cylinder body two sides are connected with cylinder head respectively, fastening by second screw, be provided with elastic film between cylinder body and the cylinder head, be provided with piston in the cylinder head, cylinder body is arranged between upper bracket and the lower carriage, locatees by alignment pin; Left-handed spring and dextrorotation spring are separately positioned on first chela and second chela, and support and support are fastening by nut and bearing pin; Cylinder body is provided with sealing gasket, and upper bracket and lower carriage are fixed on the gas frame by screw.
First chela, second chela are arranged on the bearing pin, and the axis hole length of first chela, second chela is 18～38mm; Axis hole center line to the distance between the elastomeric outer side center line is 10～30mm.Described elastomeric material is rubber or engineering plastics.
The utility model compared with prior art has following beneficial effect: 1, rationally distributed, compact conformation, has good automatic aligning performance, the spool center of promptly grabbing on pipe device Clamping Center and the spindle is consistent automatically, when running into when grabbing pipe device and spool off-centre (foozle or rigging error), a chela always contacts spool and the load force rising prior to the another chela, pneumatic means compensation automatically makes another chela cover, till two chelas are applied to pressure balance on the spool, realization is grabbed the automatic aligning of pipe device and spool and is accurately pulled out, insert spool, can guarantee to grab the pipe action accurately, stable, reliably.2, adopt the mode of side position clamping, when grasping spool, needn't as device is managed in existing grabbing, be inserted in from spool top earlier, drop to the crawl position again, but directly put into and grasp, can save non-cutting time in the clamping position; 3, has the automatic overload protection function: when running into when can not pulling out any more spool or inserting when not in place fortuitous events such as (are wound with too much residual yarn or meet barrier on bobbin distortion, the spindle); because of its chucking power keeps stable (by its structures shape); the spool that is held slippage voluntarily, thus key components and partss such as spindle, gas frame protected.4, the front end of chela is equipped with an elastomer, even produce certain wearing and tearing, does not also influence operate as normal, has prolonged service life.5, open shelves between the chela rationally; The spool of adaptive various diameters, highly versatile.

The specific embodiment
A kind of from the pneumatic pipe device of grabbing of aligning side position clamping, as shown in Figure 1, it comprises first chela 1, second chela 2, elastomer 3, cylinder body 4, cylinder head 5, piston 6, elastic film 7, alignment pin 8, nut 9, upper bracket 10, lower carriage 11, bearing pin 12, sealing gasket 13, dextrorotation spring 14, left-handed spring 15, first screw 16,17 gentle 18 on second screw, the front end of first chela 1 and second chela 2 is elastomer 3 of setting-in respectively, cylinder body 4 two sides are connected with cylinder head 5 respectively, fastening by second screw 17, be provided with elastic film 7 between cylinder body 4 and the cylinder head 5, be provided with piston 6 in the cylinder head 5, cylinder body 4 is arranged between upper bracket 10 and the lower carriage 11, by alignment pin 8 location; Left-handed spring 15 and dextrorotation spring 14 are separately positioned on first chela 1 and second chela 2, and support 10 and support 11 are fastening by nut 9 and bearing pin 12; Cylinder body 4 is provided with sealing gasket 13, and upper bracket 10 and lower carriage 11 are fixed on the gas frame 18 by screw 16.The axis hole length of first chela 1, second chela 2 is 30mm; Axis hole center line to the distance between the outer side center line of elastomer 3 is 20mm.The front end of chela is equipped with an elastomer 3, and material can be a rubber, also can be engineering plastics.
Grabbing the pipe device when being in wait state, torsion spring dextrorotation spring 14, left-handed spring 15 make chela 1 and chela 2 be in open mode.
Grabbing the pipe device when in running order, elastic film 7 is subjected to air pressure and expands, driven plunger 6 is stretched out, force chela 1, chela 2 to rotate the clamping spool around bearing pin 12, when running into when grabbing pipe device and spool off-centre (foozle or rigging error), a chela always contacts spool and the load force rising prior to the another chela, cylinder body internal gas pressure compensation automatically makes another chela cover, till two chelas are applied to pressure balance on the spool, realize grabbing the automatic aligning of pipe device and spool and accurately pull out, slotting spool.
Adopt the mode of side position clamping, when grasping spool, can directly put into and grasp, can save impulse stroke and non-cutting time in the clamping position.
Because its chucking power keeps stable (chucking power is by its physical dimension decision); when running into when can not pulling out any more spool or inserting when not in place fortuitous events such as (are wound with too much residual yarn or meet barrier on bobbin distortion, the spindle); external force is greater than chucking power; the spool that is held slippage voluntarily; thereby protected key components and partss such as spindle, gas frame, had the automatic overload protection function.Can increase elastomer 3 and be held the contact area of spool,, also not influence operate as normal, so life cycle is long even produce certain wearing and tearing.
