Description

The Yarn-spinning spindle that vertical buffering is arranged at the bottom of the flat ingot

Technical field

The utility model relates to a kind of Yarn-spinning spindle that is used for textile industry, specifically, has related to the Yarn-spinning spindle that vertical buffering is arranged at the bottom of a kind of flat ingot.

Background technology

The Yarn-spinning spindle that flat ingot die bed helicla flute elastic tube connects, existing at home at present part high-end user is using, it adopts upper support to fix, lower support is connected with upper support by elastic tube, the lower support bearing is again a composite bearing simultaneously, by radially hydrodynamic bearing and axial plane thrust bearing are formed, its advantage is: hydrodynamic bearing---copper sheathing radially, but bearing radial force, because the Hydrodynamic principle produces the supporting oil film spindle blade and copper sheathing are separated, avoided direct contact, less energy consumption; The axial plane thrust bearing---at the bottom of the flat ingot, can bear axial force, with spindle blade lower surface supporting at the bottom of the flat ingot be a big sphere, it can reduce and flat ingot basal surface compact stress, wearing and tearing are few; Spindle blade is when running up, the trend that does not have the sort of moving upward (floating) at the bottom of the taper ingot, this spindle working speed is generally below 20000～22000r/min, but this spindle is in the process of running up, because oscillation crosswise, bobbin are beated, the influence of spindle band, can produce longitudinal force and impact to spindle, and ingot speed is high more in high-speed range, longitudinal force is big more, cause the yarn tension fluctuation, end breakage rate increases, and bar evenness descends, also can influence the spindle stability that runs up simultaneously, reduce spindle service life; In order to reduce labour intensity, improve mechanical efficiency, adopt the fine spining machine long vehicle to realize collective's automatic doffing in China, but the Yarn-spinning spindle that this flat ingot die bed helicla flute elastic tube connects, owing to there is not vertical buffer unit, in fine spining machine collective automatic doffing process, be easy to be subjected to axial force and impact, cause lower support axiality variation and lost efficacy.

As shown in Figure 1: flat ingot die bed helicla flute elastic tube of the prior art connect Yarn-spinning spindle by spindle blade 1, bearing shim 2, spindle bearing 3, top chock 4, bolster 5, elastic tube 6, locating sleeve 7, wind spring 8, copper sheathing 9, flat ingot at the bottom of 10, ingot bottom flake 11 and ingot heelpiece piece 12 form, spindle blade 1 is a longaxones parts, have two bearing guards up and down, its lower end is a great circle arc sphere, is the revolving part of this spindle; Bearing shim 2, spindle bearing 3, the top chock 4 common upper supports of forming spindle supporting spindle blade 1; Bolster 5 is cylinder-like shells, is used to install other part, has the store oil function concurrently; Elastic tube 6 connects goes up lower support, has the longitudinal spiral groove on it, has certain aligning effect; Locating sleeve 7 is metal sleeves, works to isolate wind spring 8 and top chock 4; Wind spring 8 adopts the elastic metallic coil sheet to make, cylindric spring, and effect is absorbing; 10 common spindle blade 1 lower supports of forming at the bottom of the copper sheathing 9 peaceful ingots, wherein, copper sheathing 9 is hydrodynamic bearings, bearing radial force, form friction pair with

spindle blade

1,10 is axial plane thrust bearings at the bottom of the flat ingot, bears axial force, can reduce spindle blade 1 on scurry, simultaneously, contact with the big sphere in the bottom of spindle blade 1, reduce ingot point surface contact stress, reduce wear; 10 play supporting role at the bottom of 11 pairs of flat ingots of ingot bottom flake; Ingot heelpiece piece 12 is to prevent that elastic tube 6 is subjected to the external force excess impact and sinking occurs, and lower support axiality on the destruction causes spindle to lose efficacy.

The utility model content

Goal of the invention of the present utility model is at the deficiencies in the prior art, thus provide a kind of improve spindle run up stability, prolong spindle service life, can adapt to the Yarn-spinning spindle that vertical buffering is arranged at the bottom of the flat ingot of collective's automatic doffing.

In order to realize the foregoing invention purpose, the utility model provides the Yarn-spinning spindle that vertical buffering is arranged at the bottom of a kind of flat ingot, comprise at the bottom of spindle blade, bearing shim, spindle bearing, top chock, bolster, elastic tube, locating sleeve, wind spring, the copper sheathing peace ingot, be provided with vertical buffer unit in flat ingot bottom, described vertical buffer unit bottom is provided with the ingot bottom spacer, described vertical buffer unit is arranged in the described elastic tube, and described ingot bottom spacer is installed on described elastic tube bottom.

Described vertical buffer unit comprises sliding sleeve and is installed on the spring of sliding sleeve bottom; Described sliding sleeve lower central has the spring pilot hole that holds spring.

The relative prior art of the utility model has substantive distinguishing features and progressive, specifically, adopts the utility model will obtain following effect:

1, this Yarn-spinning spindle has the characteristics of vertical buffering, and the impact of collision when reducing doffing of spinning frame can adapt to collective's automatic doffing;

2, can reduce longitudinal force and the impact that spindle is born in the process of running up, improve the stability of spindle under the situation of running up, prolong the service life of spindle.
