Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of rotor spinning machines, specifically relating to a spinning device positioning mechanism for rotor spinning machines. Background Technology
[0002] The core component of a rotor spinning machine is the spinneret. During splicing, maintenance, and other processes, the spinneret needs to be opened and closed along its positioning axis. When the spinneret is opened, a limit switch needs to be placed at the lower cover to prevent it from falling. Furthermore, after repeated opening and closing, axial displacement may occur along the positioning axis, causing a misalignment between the spinneret and other mating components of the rotor spinning machine. This can lead to the spinneret malfunctioning. Therefore, existing rotor spinning machines... Spinning machines use a spinning unit positioning structure to position the spinning unit. However, in existing rotor spinning machines, the positioning structure places the positioning block of the cast aluminum part at the bottom of the spinning unit positioning shaft. When the spinning unit is opened, the lower cover of the spinning unit and the positioning block interfere with each other to limit the spinning unit's movement. However, the die-casting process of the positioning block of the cast aluminum part is complex, and the manufacturing cost of the parts is high. Moreover, during daily use, due to the impact of the opening and closing of the spinning unit, the small protrusions on the cast aluminum part are prone to breakage due to the long-term impact of the spinning unit, resulting in high maintenance costs in the later stages. Utility Model Content

By separately setting the limiting rib and the positioning component, the displacement of the lower cover of the spinning device along the axial direction of the spinning device positioning axis and the abutment limiting support after the lower cover of the spinning device is opened are respectively positioned, thereby achieving precise positioning and saving costs.
[0004] A spinning device positioning mechanism for a rotor spinning machine is provided, applicable to the rotor spinning machine. The rotor spinning machine includes a machine beam, a spinning device positioning shaft, and a spinning device body. Both the spinning device positioning shaft and the spinning device body are located on the machine beam. A lower spinning device cover is provided at the bottom of the spinning device body, and the lower spinning device cover is fitted onto the outer circumferential surface of the spinning device positioning shaft to support the spinning device body. The spinning device positioning mechanism includes:
[0005] The limiting ribs include two pieces, which are arranged parallel to each other at the bottom of the lower cover of the spinning machine. Each limiting rib has an abutment surface, which is perpendicular to the bottom surface of the lower cover of the spinning machine. When the lower cover of the spinning machine rotates along the positioning axis of the spinning machine, the abutment surface on the limiting rib abuts against the machine beam.
[0006] The positioning component includes a positioning block, the positioning block being arc-shaped in its entirety, the arc of the positioning block being equal to the arc of the outer circumference of the positioning shaft of the spinning machine, and the arc length of the positioning block being one-third of the arc length of the outer circumference of the positioning shaft of the spinning machine.
[0007] Preferably, the limiting rib is integrally formed with the lower cover of the spinning machine.
[0008] Preferably, in the positioning component, the positioning block includes a body portion and stepped portions disposed on two arc-shaped sidewalls of the body portion, wherein the height of the stepped portions is greater than the height of the body portion.
[0009] Preferably, in the positioning block, a locking hole is also provided on the main body, the locking hole is an elongated hole, and the elongated locking hole extends along the axial direction of the positioning block.
[0010] Preferably, the positioning component further includes a threaded hole on the positioning shaft of the spinning machine and a locking bolt that mates with the threaded hole.

[0013] The beneficial effects of this utility model are as follows:
[0014] In the spinning unit positioning mechanism of the rotor spinning machine provided by this utility model, a limiting rib is provided at the bottom of the lower cover of the spinning unit, and there is an abutment surface on the limiting rib. This abutment surface is perpendicular to the bottom surface of the lower cover of the spinning unit. When the lower cover of the spinning unit is opened, that is, when the lower cover of the spinning unit rotates along the positioning axis of the spinning unit, the abutment surface on the limiting rib abuts against the machine beam, thereby limiting the lower cover of the spinning unit. The limiting rib is integrally formed with the lower cover of the spinning unit, which greatly increases the service life of the limiting rib.
[0015] The positioning mechanism of the spinning machine provided by this utility model also includes a positioning component.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

In addition, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
[0023] In this technical solution, such as Figure 1 , Figure 3 As shown, a spinning device positioning mechanism for a rotor spinning machine is applied in the rotor spinning machine. The rotor spinning machine includes a machine beam 1, a spinning device positioning shaft 2, and a spinning device body 3. The spinning device positioning shaft 2 and the spinning device body 3 are both located on the machine beam 1. The bottom of the spinning device body 3 is provided with a lower spinning device cover 301, and the lower spinning device cover 301 is sleeved on the outer circumferential surface of the spinning device positioning shaft 2 to support the spinning device body 3.
[0024] For ease of understanding, it should be noted in this application that: the core of this application is to limit the axial movement of the lower cover 301 of the spinning machine towards the spinning machine positioning shaft 2 through the provided spinning machine positioning mechanism, and also to limit the opening degree of the lower cover 301 of the spinning machine when it rotates open along the spinning machine positioning shaft 2, so as to prevent the lower cover 301 of the spinning machine and the spinning machine body 3 from opening too much and affecting subsequent splicing, maintenance and other operations. However, since the spinning machine targeted in this application is a conventional device in the art in the prior art, its core includes the spinning machine body 3, and the spinning function is realized through the cooperation of the spinning machine body 3 and other equipment. The machine beam 1 and the spinning machine positioning shaft 2 are components and equipment set up to cooperate with the normal operation of the spinning machine body 3. Therefore, this application only describes the components that affect the positioning relationship of the lower cover 301 of the spinning machine. For the other components of the spinning machine and the specific operations such as splicing and maintenance of the spinning machine body 3, those skilled in the art can learn about their specific structure and operation mode through existing patent documents and other channels.
[0025] In the spinning machine positioning mechanism of this application, such as Figure 1-4 As shown, the spinning machine positioning mechanism includes a limiting rib 4 and a positioning assembly 5, wherein:
[0026] The limiting rib 4 includes two pieces, which are arranged parallel to each other at the bottom of the lower cover 301 of the spinning machine. Each limiting rib 4 has an abutment surface 401, which is perpendicular to the bottom surface of the lower cover 301 of the spinning machine. The limiting rib 4 and the lower cover 301 of the spinning machine are integrally formed.
[0027] Based on the above embodiments, when the lower cover 301 of the spinning machine rotates along the positioning shaft 2 of the spinning machine, the abutment surface 401 on the limiting rib 4 abuts against the machine beam 1, and the specific structure is as follows. Figure 3 As shown, the design of the limiting rib 4 being integrally formed with the lower cover 301 of the spinning machine greatly increases the service life of the limiting rib 4.
[0028] like Figure 1 , Figure 4As shown, the positioning component 5 includes a positioning block 501. The positioning block 501 is arc-shaped. The arc of the positioning block 501 is equal to the arc of the outer circumference of the positioning shaft 2 of the spinning machine. The arc length of the positioning block 501 is one-third of the arc length of the outer circumference of the positioning shaft 2 of the spinning machine. In addition, the positioning block 501 is made of polystyrene.
[0029] Specifically, in positioning component 5, such as Figure 4 As shown, the positioning block 501 includes a main body 502 and a stepped portion 503 provided on two arc-shaped sidewalls of the main body 502. The height of the stepped portion 503 is greater than the height of the main body 502. A locking hole 504 is also provided on the main body 502. The locking hole 504 is an elongated hole, and the elongated locking hole 504 extends along the axial direction of the positioning block 501.
[0030] The positioning component 5 also includes a threaded hole on the spinning machine positioning shaft 2 and a locking bolt 505 that mates with the threaded hole. The threaded hole is located at the bottom of the spinning machine positioning shaft 2 and on both sides of the lower cover 301 of the spinning machine, which is not shown in the figure.
[0031] Based on the above structure, when the positioning block 501 is installed on the outer circumferential wall of the spinning machine positioning shaft 2 through the cooperation of the locking bolt 505 with the threaded hole and the locking hole 504, the area between the two positioning blocks 501 is the installation area of the lower cover 301 of the spinning machine, and the two positioning blocks 501 are respectively attached to the side wall of the lower cover 301 of the spinning machine, as shown in the specific structure. Figure 1 As shown.
[0032] In this application, the overall structure of the positioning block 501 fits the positioning shaft 2 of the spinning machine, ensuring aesthetics and positioning performance while saving consumables, which helps to reduce production costs. In addition, the elongated locking hole 504 allows the locking position of the locking bolt 505 to be adjusted as needed, thereby enabling fine-tuning of the position of the spinning machine body 3, demonstrating the practicality of this utility model. On this basis, locking bosses 506 are also provided around the locking hole 504. The top of the locking bosses 506 is a plane. This arrangement ensures that the end of the locking bolt 505 fits against the plane on the locking boss 506, avoiding gaps between the locking bolt 505 and the upper surface of the arc-shaped body 502, which could easily cause scratches to the hands of workers.
[0033] Specifically, in the spinning device positioning mechanism of the rotor spinning machine provided by this utility model, when the lower cover 301 of the spinning device is sleeved and installed on the outer circumferential wall of the spinning device positioning shaft 2 through its main body structure, it is necessary to limit the position of the lower cover 301 of the spinning device in the axial direction along the spinning device positioning shaft 2. At this time, based on the cooperation between the positioning block 501 and the spinning device positioning shaft 2, a locking bolt 505 is passed through the locking hole 504 and cooperates with the threaded hole provided on the spinning device positioning shaft 2 to realize the installation of the positioning block 501. On this basis, the installation position of the positioning block 501 is specifically adjusted through the elongated locking hole 504 so that the positioning block 501 can effectively limit the position of the lower cover 301 of the spinning device and prevent its axial movement.
[0034] In addition, the present invention provides a limiting rib plate 4 at the bottom of the lower cover 301 of the spinning machine. When the lower cover 301 of the spinning machine rotates along the positioning shaft 2 of the spinning machine, the abutting surface 401 on the limiting rib plate 4 abuts against the machine beam 1, thereby limiting the opening and closing degree of the lower cover 301 of the spinning machine.
[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
