Description

Technical Field

[0001] This utility model relates to the field of spring installation technology, specifically to a joint installation structure for a spring and a rotating shaft. Background Technology

[0002] In the field of mechanical manufacturing and equipment assembly, springs, as important elastic elements, are widely used in various mechanical equipment.

[0003] Currently, in the assembly of springs and similar components such as spindles, most methods involve direct fitting. Operators need to repeatedly adjust the axial position, perpendicularity, and pre-compression of the spring manually to ensure that the spring axis is coaxial with the spindle centerline. This consumes a lot of time and manpower. Moreover, during manual adjustment, it is difficult to guarantee that the spring can be accurately positioned every time, which can easily lead to positional deviations. Deviations in the spring installation position will cause uneven force on the spring during actual operation of the equipment, resulting in abnormal vibration, which in turn causes overall equipment vibration and increased noise. Therefore, we propose a matching installation structure for springs and shafts. Utility Model Content

[0004] To solve the above-mentioned technical problems, embodiments of this application provide a mating installation structure for a spring and a rotating shaft, including a rotating shaft, a spring disposed on the rotating shaft, a sleeve disposed on the outer wall of the rotating shaft, and the spring disposed inside the sleeve, and an installation assembly disposed between the rotating shaft and the spring.

[0005] In some embodiments, the mounting assembly includes positioning holes evenly distributed on the outer wall of the spring, and positioning members disposed on the rotating shaft. The positioning members include a ring body and positioning pins connected to each other, and the positioning pins are evenly disposed on the ring body and correspond to the positioning holes.

[0006] In some embodiments, the height of the locating pins is set to increase sequentially.

[0007] In some embodiments, a friction-enhancing sleeve is provided inside the positioning hole.

[0008] In some embodiments, a limiting groove is formed on the outer wall of the ring, and a first mounting groove and a second mounting groove are formed on the bottom surface and the outer side of the ring, respectively.

[0009] In some embodiments, the top surface of the ring is symmetrically provided with clamping arms, and the clamping arms are configured as elastic structures.

[0010] In some embodiments, an inclined section is provided on one side of the clamping arm.

[0011] This utility model has at least the following beneficial effects:

[0012] With this installation structure, the operator only needs to rotate the ring to align the positioning pin and positioning hole, and then press down the spring to complete the installation, saving labor costs. It is especially suitable for the assembly process of mass-produced mechanical equipment. Moreover, because the spring is installed in an accurate and firm position, the spring is subjected to uniform force during equipment operation and will not cause abnormal vibration due to position deviation.

[0013] The design of the clamping arm and the inclined section provides additional clamping force for the spring, further enhancing the stability of the spring after installation. The setting of the limiting groove, the first mounting groove and the second mounting groove also optimizes the installation structure from different aspects. Attached Figure Description

[0020] 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.

[0021] Example 1

[0022] Please see Figures 1-5 This utility model provides a technical solution:

[0023] The spring and shaft mounting structure includes a shaft 1, a spring 2 mounted on the shaft 1, a sleeve 3 on the outer wall of the shaft 1, and the spring 2 housed within the sleeve 3. A mounting assembly 4 is positioned between the shaft 1 and the spring 2. The mounting assembly 4 includes evenly distributed positioning holes 6 on the outer wall of the spring 2, and positioning elements 5 on the shaft 1. Each positioning element 5 includes a connected ring 8 and positioning pins 11, with the positioning pins 11 evenly distributed on the ring 8 and corresponding to the positioning holes 6. The height of each positioning pin 11 increases progressively. A friction-enhancing sleeve 7 is installed within the positioning holes 6. Eight positioning holes 6 are evenly distributed on the outer wall of the spring 2. The positioning hole 6 is machined using a drilling process. The friction-enhancing sleeve 7 is made of nitrile rubber, which has good wear resistance and elasticity. The inner diameter of the friction-enhancing sleeve 7 is installed in the positioning hole 6 through an interference fit. The presence of the friction-enhancing sleeve 7 can increase the friction between the positioning pin 11 and the positioning hole 6, ensuring the stability of the positioning. The ring body 8 is fitted on the rotating shaft 1. The positioning pin 11 is made of cylindrical pins and is evenly distributed on the ring body 8. The number of positioning pins is the same as that of the positioning holes 6, and their height is set to increase progressively. This progressive height design allows the spring 2 to be adapted to positioning holes 6 of different heights when it is installed, ensuring that it can be inserted into the positioning hole 6.

[0024] In use, first, sleeve 3 is placed on shaft 1, then spring 2 is placed inside sleeve 3, then ring 8 is placed on shaft 1, and then spring 2 is pressed down so that positioning pin 11 is inserted into positioning hole 6. Friction-enhancing sleeve 7 is in close contact with positioning pin 11, providing sufficient friction to prevent axial movement and rotation of spring 2 during use. In this way, spring 2 can be installed quickly and accurately without repeated manual adjustment by operators, improving installation efficiency and positioning accuracy.

[0025] Example 2

[0026] Please see Figures 1-5 This utility model provides a technical solution:

[0027] A limiting groove 9 is formed on the outer wall of the ring body 8. A first mounting groove 10 and a second mounting groove 14 are formed on the bottom and outer sides of the ring body 8, respectively. A clamping arm 12 is symmetrically arranged on the top surface of the ring body 8, and the clamping arm 12 is designed as an elastic structure. An inclined section 13 is provided on one side of the clamping arm 12. A limiting groove 9 is formed on the outer wall of the ring body 8, and the cross-section of the limiting groove 9 is rectangular. Its function is to cooperate with the spring 2. The first mounting groove 10 and the second mounting groove 14 are used to install other auxiliary components that cooperate with the ring body 8, preventing the ring body 8 from rotating circumferentially on the rotating shaft 1, ensuring the relative position of the positioning pin 11 and the positioning hole 6 is fixed, thereby ensuring the stability of the spring 2 after installation. The clamping arm 12 has good elasticity. The shape is L-shaped, with one end fixedly connected to the top surface of the ring 8 and the other end suspended freely, allowing for elastic deformation within a certain range. The inclined section 13 is integrally formed with the clamping arm 12. When the spring 2 is installed, after the spring 2 is pressed down and the positioning pin 11 is inserted into the positioning hole 6, the top of the spring 2 will contact the inclined section 13 of the clamping arm 12. As the spring 2 continues to be pressed down, the clamping arm 12 will undergo elastic deformation, generating an inward clamping force on the spring 2, further fixing the position of the spring 2 and preventing the spring 2 from coming off upward during use. At the same time, the design of the inclined section 13 makes it easier for the spring 2 to contact the clamping arm 12 and trigger the clamping action during installation, improving the convenience and stability of installation.

[0028] Unlike Embodiment 1, the function of the positioning component 5 is further optimized by adding structures such as the limiting groove 9, the first mounting groove 10, the second mounting groove 14, the clamping arm 12, and the inclined section 13. The limiting groove 9 enhances the positioning stability of the ring 8 and prevents its circumferential rotation; the first mounting groove 10 and the second mounting groove 14 facilitate the installation and cooperation of the ring 8 with other components; and the clamping arm 12 and the inclined section 13 provide additional clamping force after the spring 2 is installed, further ensuring the secure installation of the spring 2 and reducing the risk of positional displacement of the spring 2 during use.

[0029] Working principle:

[0030] When installing spring 2 and shaft 1, the operator first puts sleeve 3 on shaft 1 to provide radial limiting space for spring 2, then puts spring 2 into sleeve 3, then puts ring 8 with positioning pin 11 on shaft 1, and then presses spring 2 down, positioning pin 11 is inserted into positioning hole 6, positioning pin 11 is in close contact with friction sleeve 7, the high friction characteristics of friction sleeve 7 restrict the movement of positioning pin 11 in positioning hole 6, thereby fixing spring 2 on shaft 1 in the axial direction, and also ensuring the perpendicularity of spring 2. In this way, the tedious process of repeated manual adjustment is avoided.

[0031] When spring 2 is pressed down and the positioning pin 11 is inserted into the positioning hole 6, the top of spring 2 contacts the inclined section 13 of clamping arm 12. As spring 2 continues to press down, clamping arm 12 is squeezed by spring 2 and undergoes elastic deformation, generating a reverse elastic force. This elastic force acts on spring 2, forming an inward clamping force. This clamping force, together with the friction of positioning pin 11 and friction-enhancing sleeve 7, fixes spring 2 in both axial and radial directions, further improving the firmness of spring 2 installation. At the same time, the first mounting groove 10 and the second mounting groove 14 facilitate the installation and cooperation of ring body 8 with other auxiliary components, restrict the axial rotation of ring body 8, ensure that the relative position of positioning pin 11 and positioning hole 6 remains unchanged, guarantee the stability of spring 2 after installation, and make the entire installation and adjustment process more convenient and accurate.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
