Abstract
An extension bolster consists of a bolster body fixed on a tendon, a bobbin gear nested outside the bolster body, a thrust element arranged inside the bolster body and an extension bolster driven by the thrust element, wherein, a chamber for containing the thrust element is arranged inside the bolster body and is provided with an air inlet in the rearward; the outer of the bolster is encased with the bobbin gear, the upper part of the bolster body is provided with a locating cap; the extension bolster is fixed with the thrust element. When a full tube is taken away and an empty tube is to be placed, the thrust element pushes out the extension tube of the bolster to increase the length of the bolster, thereby lengthening the matching surface of the bobbin gear and the bobbin so as to ensure accurate placing of the empty tube.
Description
Technical field
The utility model relates to a kind of doffing device of Speed frames, and especially the bolster device of Speed frames doffing device is more suitable for spindle blade formula Speed frames.
Background technology
The bolster device is the important device in the Speed frames Automatic doffing devices, textile technology circle personage both domestic and external, endeavour research one after another the pipe that falls through is accurately put in place, as disclosed No. 90202385.3 patents " a kind of high speed bolster ", but existing technology, still can not satisfy the requirement that the pipe that falls through accurately puts in place, especially on last spindle blade formula Speed frames, because that the bobbin gear supports the mating surface of bobbin is short, referring to a shown in Figure 1 portion mating surface, pipe is difficult for accurately putting in place so fall through, and bobbin (A) easily falls; Industry is demanded a kind of technology that is suitable on existing main frame of quoting urgently, solves the problem that bobbin easily falls when falling through pipe.
Summary of the invention
Problem to be solved in the utility model is, overcomes the above-mentioned defective that aforementioned techniques exists, and the retractable bolster of a kind of extensible bobbin gear and bobbin mating surface is provided.
The utility model solves its technical problem and takes following technical scheme to realize, a kind of retractable bolster that provides according to the utility model, the thrust component of installing by the bobbin gear (2) that is packed in bolster body (1) on the rail (3), this bolster body exterior suit, bolster body interior (4), and the retractable bolster (5) of the mating surface of extensible lengthening bobbin gear and bobbin form
The chamber (11) of ccontaining thrust component is set in the described bolster body (1), and leaves into hole at the rear portion, the bobbin gear (2) of this bolster body exterior suit, this bolster body top is provided with positioning cap (12); Retractable bolster (5) is installed in the bolster body (1), is fixedly connected with thrust component (4).
The utility model solves its technical problem and can also take following technical scheme further to realize:
Aforesaid retractable bolster wherein, is provided with positioning key (21) on the bobbin gear, this positioning key can be set to tip;
Aforesaid retractable bolster wherein, is provided with alignment pin (121) on the positioning cap on the bolster body (12); The pin-and-hole (51) that allows this alignment pin (121) to inject in any suitable position is set on the bottom circumference of described retractable bolster (5);
Aforesaid retractable bolster, wherein, the retractable bolster top is provided with flange (52);
Aforesaid retractable bolster, wherein, described thrust component (4) is cylinder or Hydraulic Elements or spring.
The utility model compared with prior art has significant advantage and beneficial effect.By above technical scheme as can be known, the utility model has following advantage at least under the structural arrangements of excellence:
Removed when full packages, when falling through pipe, thrust component is released the telescoping tube of bolster, and the length of having extended bolster extends the mating surface of bobbin gear and bobbin, guarantees the pipe that accurately falls through; Simple in structure, effect is remarkable, and is easy to implement, is more suitable for quoting on original machine, and the utility model contrast prior art has significant contribution and progress, is the good technology with novelty, creativeness, practicality really.
The specific embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Structural representation when Fig. 1 is the indentation of the utility model retractable bolster;
Fig. 2 is the structural representation of the utility model retractable bolster insertion in use bobbin;
Fig. 3 is that the utility model package assembly A is to the schematic diagram of looking;
Fig. 3 A is that the utility model package assembly B is to the schematic diagram of looking.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the specific embodiment, structure, feature and effect thereof that foundation the utility model is provided, describe in detail as after.
Shown in Fig. 1-3A, a kind of retractable bolster, the cylinder of installing by the bobbin gear (2) that is packed in bolster body (1) on the rail (3), this bolster body exterior suit, bolster body interior (4), and the retractable bolster (5) of extensible lengthening bobbin gear and bobbin mating surface form
The chamber (11) of ccontaining cylinder is set in the described bolster body (1), and leaves air admission hole at the rear portion, the bobbin gear (2) of this bolster body exterior suit, this bolster body top is provided with positioning cap (12); Alignment pin (121) is set on this positioning cap (12); The positioning key (21) that is provided with on the described bobbin gear is set to tip, being beneficial to bobbin inserts, equally be provided with bearing with taking over technology in this bobbin gear, do not repeat them here, bar (41) on retractable bolster (5) and the cylinder (4) is fixedly connected with nut, and is flexible in order to promote retractable bolster (5); The pin-and-hole (51) that alignment pin (121) on the permission bolster body injects in any suitable position is set on the bottom circumference of described retractable bolster (5), retractable bolster (5) does not change when making the bobbin gear rotate, this retractable bolster top is provided with flange (52), when falling through pipe, bolster stretches into bobbin (A) inner chamber, bobbin mating surface lengthening, bobbin is not crooked, and the problem of fundamentally having avoided bumping bobbin occurs.Aforesaid thrust component (4) also can adopt Hydraulic Elements or spring, and the chamber (11) that is provided with in the aforesaid bolster body should be provided with Hydraulic Elements that adopted or spring coupling.
The utility model is the important device of Speed frames automatic doffing mechanism, in each bobbin gear, a bolster that can stretch is all arranged, be retracted mode shown in Figure 1 at ordinary times, removed when full packages, before the pipe that falls through, thrust component is released the telescoping tube of retractable bolster, be the state that stretches out shown in Figure 2, the length of having extended bolster, the mating surface of extended bobbin gear and bobbin is guaranteed the pipe that accurately falls through.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
