Description

Technical Field

[0001] This utility model relates to a working height adjustment mechanism for a pressure cradle in a ring spinning drafting system of textile machinery, specifically an anti-loosening and anti-rotation mechanism for a spring-loaded pressure cradle height adjustment component. Background Technology

[0002] Currently, adjusting the position, direction, or force of mechanical equipment using adjusting screws is a common technique. We all hope that once the appropriate position, direction, or force is achieved, it will remain unchanged. Usually, this can be achieved by adding a locking nut. However, when there is insufficient space, or when the space is inconvenient for installing or tightening the locking nut, other methods are needed to prevent the adjusting screw from loosening and rotating. Specifically in the textile industry, in the past, the height adjustment component of a spring-loaded cradle was adjusted using adjusting screws mounted on the cradle base during the pressure adjustment process. This involved changing the engagement length to achieve the required working height of the cradle. Once the appropriate working height was reached, the adjusting screw was tightened. However, because the cradle vibrates for extended periods during operation, the adjusting screw may gradually loosen, affecting adjustment accuracy and leading to a decrease in product quality. Furthermore, the limited space within the cradle base makes it difficult to prevent the adjusting screw from loosening by adding a locking nut. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides an anti-loosening and anti-rotation mechanism for a spring-loaded cradle height adjustment assembly that can be used in a limited space.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a non-loosening and anti-rotation mechanism for a spring-pressurized cradle height adjustment assembly, which includes a cradle height adjustment assembly and a cradle base. The height adjustment assembly adjusts the pressure by adjusting the screw set on the cradle base. The cradle base includes two fixedly arranged side plates. The adjusting screw is installed between the two side plates. A rubber ring is interference-fitted on the nut of the adjusting screw. The outer wall of the rubber ring abuts against the side walls of the two side plates.

[0005] Preferably, the two side plates are arranged in parallel, and the outer wall of the rubber ring includes two parallel planes, which are respectively attached to the side walls of the corresponding side plates.

[0006] Preferably, the outer wall of the rubber ring is square.

[0007] Preferably, the outer periphery of the nut is provided with axial texture.

[0008] Preferably, the depth of the axial texture is greater than 0.05 mm.

[0009] Preferably, the nut is cylindrical.

[0010] Preferably, the rubber ring has a circular hole at its center, which is press-fitted with a cylindrical nut.

[0011] Preferably, the rubber ring is made of an elastic material.

[0012] Preferably, the elastic material is made of rubber or silicone.

[0013] As can be seen from the above technical solution, the present invention has an interference fit rubber ring on the nut of the adjusting screw, which not only prevents the adjusting screw and the rubber ring from easily rotating relative to each other, but also utilizes the rigidity of the fixed side plate to press the rubber ring between the side walls of the two side plates, preventing the rubber ring from rotating. Thus, the adjusting screw is fixed and prevented from rotating when the installation and operation space is limited, thereby improving the stability and reliability of the working height adjustment accuracy of the pressure rocker.

[0017] The present invention will now be described in detail with reference to the accompanying drawings. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0018] like Figure 1 , Figure 2 and Figure 3 This utility model provides an anti-loosening and anti-rotation mechanism for a spring-loaded cradle height adjustment assembly, which includes a cradle 1 height adjustment assembly 2 and a cradle base 3. The height adjustment assembly adjusts the working height by means of an adjusting screw 4 set on the cradle base. The cradle base 3 includes two fixed side plates 31. The adjusting screw 4 is installed between the two side plates. A rubber ring 5 is interference-fitted onto the nut 41 of the adjusting screw. The outer wall of the rubber ring abuts against the side walls of the two side plates. Thus, by fixing the adjusting screw with the rubber ring, its rotation can be prevented, thereby improving the stability and reliability of the working height adjustment accuracy of the pressure cradle.

[0019] Specifically, the two side plates are arranged in parallel, and the outer wall of the rubber ring 5 includes two parallel planes 51. These two planes are respectively attached to the side walls of the corresponding side plates, thereby preventing the rubber ring from rotating. Preferably, the outer wall of the rubber ring is square, which is convenient to process and quick to install. During implementation, the outer periphery of the nut can be provided with axial texture 42. When the nut and the rubber ring are in an interference fit, the axial texture will be embedded into the inner wall of the rubber ring to form a mesh, thereby further preventing relative rotation between the rubber ring and the adjusting screw. Preferably, the depth of the axial texture is greater than 0.05mm, which can ensure the rigidity of the nut while making the mesh tighter.

[0020] The nut of this invention is cylindrical, which facilitates processing. Correspondingly, a circular hole 52 is provided in the center of the rubber ring. This hole has an interference fit with the cylindrical nut, and the axial texture is embedded in the inner wall of the hole, greatly improving the tightness of the fit. The rubber ring is made of an elastic material to prevent damage to the rocker seat and the nut. Specific elastic materials can be rubber or silicone. During operation, the screw 43 of the adjusting screw is first adjusted to the precise screwing depth required for the rocker's operation. Then, the rubber ring is placed on the nut of the adjusting screw. Because the inner hole of the rubber ring is slightly smaller than the outer diameter of the nut, the axial texture of the nut's outer circumference is embedded in the inner hole of the rubber ring, forming a mesh, preventing the screw from easily rotating relative to the rubber ring. Simultaneously, a pair of parallel planes on the outside of the rubber ring are pressed against a fixed rigid parallel plane, i.e., close to the side walls of the two side plates. Thus, the rubber ring will not rotate, and under certain conditions, the adjusting screw will also not rotate, thereby achieving the purpose of preventing loosening and rotation. Therefore, it can be seen that this utility model improves the stability and reliability of the height adjustment accuracy of the pressure cradle by fixing the adjusting screw with a rubber ring when the installation and operation space of the cradle seat is limited.
