Description
Technical field
The utility model relate to change spool in a kind of doffing of spinning frame system automatically grab the pipe device.
Background technology
What be used for doffing of spinning frame system automatic replacing spool at present grabs its structure of pipe device as shown in Figure 1, cylinder seat 6 one sides are fixed on the gas pipeline 1 by bolt 4 and screw 5, the cylinder seat opposite side is provided with cylinder head 9, cylinder head 9 is provided with the grasping hole 10 that spool 11 upper ends can be stretched into, be provided with piston 8 in the cylinder seat inner chamber, return spring 7 is housed on the piston, piston 8 one ends lead to grasping hole 10 1 sides of cylinder head by the through hole on the cylinder seat 6, are provided with the air bag 3 of sealing between the passage 2 of cylinder seat inner chamber and gas pipeline.When changing spool, input gas in the gas pipeline passage 2 promotes piston 8 by air bag 3 and moves ahead, and piston nose stretches in the grasping hole 10, thereby spool 11 is pressed on another sidewall of cylinder head grasping hole spool is held, can descend the step to change the spool action.Thereby this shortcoming of grabbing the pipe device is the spool upper end must run-off the straight cause spindle 12 to tilt under the extruding of piston, although the angle of this inclination is very little, but under the rotating speeds of spindle per minute up to 4.5 ten thousand commentaries on classics of fine spining machine, the wearing and tearing of spindle are accelerated in this small inevitable back of inclination, cause reduce its service life.
Summary of the invention
The purpose of this utility model provide a kind of be used for fine spining machine grab the pipe device, can not cause spool to tilt during grasping, can reduce the wearing and tearing of spindle, the service life of improving spindle from face.
The utility model be achieved in that be used for fine spining machine grab the pipe device, comprise cylinder seat, cylinder seat one side is provided with and is used for the cylinder head of grasping spool, cylinder head is provided with the grasping hole that the spool upper end can be stretched into, be fixed with an air bag on the inwall of grasping hole, cylinder seat is provided with inlet channel, and inlet channel one end leads to the grasping hole and communicates with the inflatable chamber of air bag, and the other end communicates with the passage of gas pipeline.When changing spool, input gas in the gas pipeline feeds in the air bag by the inlet channel on the cylinder seat, air bag under the effect of air-flow in the grasping hole to cardiectasis, spool is held tightly, realize spool is held.Because spool is to cardiectasis.Around spool, hold spool tightly, therefore can not cause the inclination of spool, can prevent the spindle wearing and tearing of tilting to cause because of spool effectively.
Air bag of the present utility model can adopt following structure to be connected with cylinder head: cylinder head grasping hole outer wall upper and lower side is respectively equipped with annular groove, described air bag is a cyclic spring band, the upper and lower side of air bag has the projection that matches with the annular groove of grasping hole outer wall upper and lower side, air bag is fixed on the outer wall of cylinder grasping hole by projection, and grasping hole upper and lower side outer wall is provided with air bag is pressed on clamp ring on the outer wall of grasping hole.Gap between air bag and the grasping hole inwall forms the middle inflatable chamber of air bag like this.
For the ease of the inflatable chamber ventilation to air bag, a said cylinder grasping hole inwall is provided with the cannelure that communicates with inlet channel.
A said cylinder grasping hole outer wall and upper end are provided with dust cap, fall in the grasping hole to prevent dust, pollute and the destruction air bag.
For convenience with being connected of gas pipeline, cylinder seat has the bayonet socket that is connected with gas pipeline with the upper and lower side of gas pipeline connecting portion, the bayonet socket outer wall is provided with external tooth, the gas pipeline corresponding site is provided with the internal tooth that cooperates with external tooth, the bayonet socket inboard is provided with groove, is equipped with in the groove external tooth is pressed on spring leaf on the internal tooth.Realize being connected fast by adopting tension force bayonet socket and gas pipeline.
The utility model is realized grabbing, putting can not causing the inclination of spool by spool to cardiectasis and contraction by the air bag that is arranged in the grasping hole, can prevent effectively that the spindle that tilts to cause because of spool from wearing and tearing, and improves the service life of spindle.
