Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to the spindle seat and semi-rigid support spindle of textile spindle in textile machinery components. Background Technology

[0002] Textile spindles are an important component in textile machinery, used to mount yarn bobbins for yarn feeding. The spindle rod on which the yarn bobbins are mounted is driven to rotate by the machine's drive belt. The spindle rod is rotatably mounted on the spindle seat. The spindle has two states on the loom frame: a working state and a non-working state where it swings out to change yarn bobbins. Whether it is the side-pull hollow spindle assembly disclosed in Chinese Patent Publication No. CN209836416U or the inclined vibration-damping hollow spindle disclosed in CN209836415U, the spindle seat needs to have a support cylinder or two spaced support rings to support the rotation of the spindle rod. The support cylinder or support rings are integrally set with the base of the spindle seat. In other aspects, the spindle also has a structure that allows it to be mounted on the loom frame and swing out.

[0003] Existing spindles, including those disclosed in the two patent documents mentioned above, have a bearing fitted on the spindle rod and a damping ring for reducing vibration. The damping ring is located between the outer ring of the bearing and the inner wall of the support ring, or between the inner ring of the bearing and the spindle rod. This bearing damping ring installation structure can be found in a type of twisted ring spindle disclosed in Chinese Patent Publication No. CN119265765A. Figure 1 As shown, the disadvantages of this structure are that circumferential displacement will occur between the arranged O-rings and the bearing rings they contact, making the damping rings prone to damage. During the spindle assembly process, it is difficult to tightly squeeze them into the annular space, which also easily damages the damping rings. Moreover, the performance of the damping rings is significantly affected by temperature. In short, the existing damping structure of the spindle affects the service life of the spindle and increases the cost of using and maintaining the spindle. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a spindle seat and a semi-rigid support spindle for a textile spindle, which overcomes the problem of easy damage to the shock-absorbing ring in the shock-absorbing structure of existing spindles during installation and use.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A spindle holder for a textile spindle has a base. A first outer support ring for supporting the spindle rod is integrally formed on the base. At least two first outer support rings are coaxially spaced on the base. The first outer support rings are circumferentially disconnected, that is, the first outer support ring is formed by two arc-shaped clamping arms extending from the base, with a gap between the extended ends of the two arc-shaped clamping arms. The extended ends of the two arc-shaped clamping arms each have a coaxial through hole and a threaded hole, and also have clamping bolts. The spindle holder is pulled closer to the extended ends of the two arc-shaped clamping arms by the clamping bolts passing through the through holes and tightened on the threaded holes, so as to achieve clamping and positioning of the rotary support member installed on the spindle rod.

[0007] Specifically, the base is integrally provided with a second outer support ring that supports the spindle mounting shaft. The axis of the second outer support ring is parallel to the axis of the first outer support ring so that the spindle seat is suitable for side-pulling spindles.

[0008] Specifically, the base is integrally provided with a hinge portion so that the spindle seat is suitable for inclined spindles.

[0009] A semi-rigid support spindle has a spindle rod and a spindle seat. The spindle rod is rotatably mounted on the spindle seat. A damping device is provided between the spindle seat and the spindle rod to reduce the vibration of the spindle seat caused by the rotation of the spindle rod. The spindle seat has a base, on which a first outer support ring for supporting the spindle rod is integrally provided. The first outer support ring consists of at least two coaxially spaced rings on the base. The first outer support ring is circumferentially discontinuous, that is, it is formed by two arc-shaped clamping arms extending from the base, with a gap between the extended ends of the two arc-shaped clamping arms. The extended ends of the two arc-shaped clamping arms have coaxial through holes and threaded holes, and also have clamping bolts. The spindle seat is pulled closer to the extended ends of the two arc-shaped clamping arms by the clamping bolts passing through the through holes and tightened on the threaded holes, so as to achieve clamping and positioning of the damping device.

[0010] The shock absorption device is a semi-rigid bearing housing, which is an integral part having an inner ring, an outer ring, and an elastic body formed between the inner and outer rings. The structure in which the spindle is rotatably mounted on the spindle seat is such that a bearing is installed on the spindle, the inner ring of the semi-rigid bearing housing is tightly fitted on the outer ring of the bearing, and the first outer support ring is clamped on the outer ring of the semi-rigid bearing housing.

[0011] Specifically, the spindle has a spindle mounting shaft that pulls the spindle sideways onto the frame, and a second outer support ring is integrally provided on the base to support the spindle mounting shaft, the axis of the second outer support ring being parallel to the axis of the first outer support ring.

[0012] Specifically, the substrate is integrally provided with a hinged part for mounting the spindle obliquely on the frame.

[0013] The beneficial effects of this utility model are: This utility model uses an open-type support ring to install the spindle rod, which makes it convenient to install the shock absorption device of the spindle rod on the support ring. The shock absorption device is not easily damaged. Designing the shock absorption device as a semi-rigid bearing ring can further improve the life and shock absorption capacity of the shock absorption device. The spindle has low noise and low use and maintenance costs. Attached Figure Description

[0020] The present invention will now be further described with reference to the accompanying drawings, which are simplified schematic diagrams illustrating only the basic structure of the present invention and therefore only show the components relevant to the present invention.

[0021] Spindle holder example 1:

[0022] As attached Figure 1A spindle holder for a textile spindle has a base 1. A first outer support ring 3 is integrally formed on the base 1 to support a spindle rod 2. Three first outer support rings 3 are coaxially spaced on the base 1 and are circumferentially discontinuous; that is, each first outer support ring 3 is formed by two arc-shaped clamping arms extending from the base 1, with a gap between the extended ends of the two arc-shaped clamping arms. The extended ends of the two arc-shaped clamping arms each have a coaxial through hole and a threaded hole, and also a clamping bolt. The spindle holder is secured by the clamping bolts passing through the through hole and tightened into the threaded hole. The two arc-shaped clamping arms are brought closer together to clamp and position the rotary support mounted on the spindle rod 2. Clamping bolts, through holes, and threaded holes are common parts and structures, not shown in the attached drawings. Hex socket head cap screws can be used for clamping bolts. The base 1 is integrally provided with a second outer support ring 5 that supports the spindle mounting shaft 4. There are two second outer support rings 5 ​​spaced apart. The axis of the second outer support ring 5 is parallel to the axis of the first outer support ring 3 so that the spindle seat can be adapted to the side-pulling spindle. The second outer support ring 5 can also be a single ring with increased height.

[0023] Spindle holder embodiment 2:

[0024] As attached Figure 2 Another type of spindle holder is a spindle holder suitable for inclined spindles. The base 1 is integrally provided with a hinge part 6. The base 1 is also designed in a dispersed form to better connect the first outer support ring 3 and the hinge part 6. The base 1 also avoids hindering the clamping deformation of the first outer support ring 3. There are two first outer support rings 3 on this spindle holder.

[0025] In the two embodiments described above, the spindle holder can be made of aluminum alloy castings.

[0026] Spindle Example:

The spindle rod 2 is rotatably mounted on the spindle seat, and the spindle seat uses an attached... Figure 1 The structure shown includes a damping device between the spindle seat and the spindle rod 2 to reduce vibration of the spindle seat caused by the rotation of the spindle rod 2. The spindle seat has a base 1, on which a first outer support ring 3 supporting the spindle rod 2 is integrally formed. The first outer support ring 3 consists of three coaxially spaced rings on the base, and is circumferentially discontinuous. That is, the first outer support ring 3 is formed by two arc-shaped clamping arms extending from the base 1, with a gap between the extended ends of the two arc-shaped clamping arms. The extended ends of the two arc-shaped clamping arms each have a coaxial through hole and a threaded hole, and also a clamping bolt. The spindle seat is pulled closer to the extended ends of the two arc-shaped clamping arms by the clamping bolts passing through the through holes and tightened on the threaded holes, thereby clamping and positioning the damping device. The damping device is a semi-rigid bearing seat 7, as shown in the attached figure. Figure 4 As shown, attached Figure 4The diagram illustrates the support structure at one location. At least one of the other two locations (the first outer support ring 3) uses the same semi-rigid bearing housing 7. The semi-rigid bearing housing 7 is an integral part comprising an inner ring 7-1, an outer ring 7-2, and an elastic body 7-3 formed between the inner ring 7-1 and the outer ring 7-2. This semi-rigid bearing housing 7 is a separately manufactured part, formed by injecting cold-cured plastic material between the inner ring 7-1 and the outer ring 7-2 using a mold. The structure where the spindle 2 is rotatably mounted on the spindle seat involves mounting a bearing 8 on the spindle 2. The inner ring 7-1 of the semi-rigid bearing housing 7 is tightly fitted onto the outer ring of the bearing 8, and the first outer support ring 3 is clamped onto the outer ring 7-2 of the semi-rigid bearing housing 7. To achieve axial positioning of the spindle 2 and dust protection for the bearing 8, additional... Figure 4 The upper part also has a support step at the lower end of the inner wall of the first outer support ring 3, and a spring groove on the inner wall near the upper opening. The semi-rigid bearing seat 7 also has a spring groove on the inner wall near the upper opening. Spring clips are provided in the two spring grooves. Dust covers are provided above and below the bearing 8. Of course, the spindle has a spindle mounting shaft 4 that pulls the spindle to the side and mounts it on the frame. The base 1 is integrally provided with a second outer support ring 5 that supports the spindle mounting shaft 4. The axis of the second outer support ring 5 is parallel to the axis of the first outer support ring 3.

[0028] Based on the above technical content, if the structure of embodiment 2 of the spindle holder is used, the spindle can also be made into an inclined spindle.

[0029] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
