Abstract
The utility model relates to a fluted bobbin for spinning and weaving machines, providing a novel fluted bobbin structure suitable for super plasticity forming and arranging a bearing seat at the middle part of the fluted bobbin. The utility model is characterized in that an upper cover (1) and a bottom cover (3) are fixed on a barrel body (2); sleeves (4) is arranged in the holes of the upper cover (1) and the bottom cover (3); the inner sides of the fixedly mounted contact surfaces of the upper cover (1), the bottom cover (3) and the barrel body (2) are respectively provided with positioning blocks (5); the inner bores of the sleeve (4) are two stepped holes for installing d 1, d 2 of a rolling shaft sleeve; the appearance of the sleeve (4) can form a circular shape, a rectangular shape or any polygonal shape.
Description
The utility model relates to carrying byssaceous material or coiling web, particularly textile machines groove drum.
Present textile machines groove drum profile has conical butt and cylindrical, according to different type of drive, roughly be divided into two kinds of structures: a kind of is that the groove drum two-port directly cooperates transmission with transmission shaft, is the hollow structure that stainless steel material is made as the disclosed groove drum structure of CN2132726Y; CN1086429A discloses a kind of employing superplastic grooved alloy drum and manufacturing process and device.The weak point that above-mentioned type of drive exists is that driving torque is bigger, and rotating speed is low.Another drive mechanism is that the midway location of groove drum has bearing seat, as the groove drum structure on Japan's " field, village " bobbin-winding machine, the method of cylindrical shell and upper and lower cover and bearing seat employing casting processing is processed as one, the advantage of this structure is that moment of torsion is little, power is little, the rotating speed height, stable working, but the weak point of its existence is owing to the contour structures complexity, and casting processing groove drum surface is more coarse, precision is lower, must replenish processing through high-precision numerical control machine and just can reach the groove drum dimension precision requirement, difficulty of processing is big, and conformability is poor, equipment investment is big, and cost is higher.
The purpose of this utility model provides a kind of novel groove drum structure that is suitable for superplastic forming, and has bearing seat at the midway location of groove drum, welding fabrication after the also available steel plate punching press of this groove drum structure.
The utility model is to realize like this.A kind of textile machines groove drum, comprise the cylindrical shell that has V-type guide groove, bearing seat in the lid at cylindrical shell two ends and the cylindrical shell is characterized in that loam cake (1), bottom (3) are fixed on the cylindrical shell (2), and sleeve (4) is installed in the hole of loam cake (1) and bottom (3).Loam cake (1), bottom (3) are separately installed with locating piece (5) with the hard-wired contact surface of cylindrical shell (2) inboard.Sleeve (4) endoporus is for installing the d of antifriction-bearing box
1, d
22 stepped holes, the profile of sleeve (4) can be circle, square or arbitrary polygon.
Compare with background technology, the beneficial effects of the utility model are to have solved the difficult problem that superplastic forming can not processed tape spool bearing in the middle of the groove drum, groove drum is in light weight, enough strength and stiffness is arranged, any surface finish, the precision height, high conformity, and former is simple, invests little, produce the preparatory period weak point, be easy to reach the standard grade.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the enforcement illustration of sleeve (4), and sleeve configuration is a polygon.
Be described further below in conjunction with embodiment.Earlier groove drum is divided into 4 parts and processes respectively, then be installed as one again, loam cake (1), bottom (3) are fixed on the cylindrical shell (2) that has V-type guide groove, and sleeve (4) is installed in the hole of loam cake (1) and bottom (3).
Cylindrical shell (2), sleeve (4) are realized with the superplastic forming job operation, also can use the steel plate it by punch and weld.Sleeve (4) uses as the groove drum middle bearing bracket, and sleeve (4) endoporus is for installing the d of antifriction-bearing box
1, d
22 stepped holes, the profile of sleeve (4) can be circle, square or arbitrary polygon.As shown in Figure 2, the sleeve configuration of present embodiment is a polygon.One side of sleeve (4) can be established opening A, is convenient to add counterweight, also opening not.
Loam cake (1), bottom (3) can adopt the superplasticity processing technology, also can adopt the processing of casting processing or other common machining method, and loam cake (1), bottom (3) are connected with welding or riveted joint with cylindrical shell (2).Locating piece (5) is fixed on the inboard of cylindrical shell (2), is used for the fixing and location of loam cake and bottom.
Sleeve (4) is installed in the endoporus of loam cake (1), bottom (3), and available screw connects, and is perhaps integrally welded.Sleeve (4) also can be used as an integral body with bottom (3).
The utility model is not only applicable to conical butt groove drum structure, and is applicable to the cylindrical groove barrel structure.
Claims (4)
1, a kind of textile machines groove drum, comprise the cylindrical shell that has V-type guide groove, bearing seat in the lid at cylindrical shell two ends and the cylindrical shell, it is characterized in that: loam cake (1), bottom (3) are fixed on the cylindrical shell (2), and sleeve (4) is installed in the hole of loam cake (1) and bottom (3).
2, groove drum according to claim 1 is characterized in that loam cake (1), bottom (3) are separately installed with locating piece (5) with the hard-wired contact surface of cylindrical shell (2) inboard.
3, groove drum according to claim 1 is characterized in that sleeve (4) endoporus is for installing the d of antifriction-bearing box
1, d
22 stepped holes.
4, groove drum according to claim 1 is characterized in that the profile of sleeve (4) can be circle, square or arbitrary polygon.
