[0036] Clearly, the described embodiments are merely part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0037] Please refer to Figures 1-11 A damping structure for a galloping spindle in a high-speed braiding machine, comprising a rack 100, an upper disc surface 101 and a lower disc surface 102 are fixedly arranged on the rack 100, a transmission cavity 103 is pre-set between the upper disc surface 101 and the lower disc surface 102, a galloping spindle 104 and an impeller 105 are arranged on the upper disc surface 101;

[0038] A plurality of annular guide tracks 106 are formed in the upper disc surface 101 in communication, the galloping spindle 104 is slidingly fitted in the annular guide tracks 106, the impeller 105 is rotationally installed at the center of the annular guide tracks 106, and a transmission member for driving the impeller 105 to rotate is arranged in the transmission cavity 103;

[0039] A plurality of accommodation grooves 111 are formed in the circumferential direction of the impeller 105, the galloping spindle 104 comprises a sliding block 107 slidingly fitted in the annular guide tracks 106, a spindle seat 108 is rotationally arranged on the upper end surface of the sliding block 107, a connecting column 109 and a mounting seat 110 are sequentially fixedly connected to the upper end surface of the spindle seat 108, and the connecting column 109 is transmissionally fitted in the accommodation grooves 111;

[0040] A plurality of U-shaped accommodation blocks 112 are respectively arranged on the inner walls of the accommodation grooves 111, a split elastic assembly 113 is arranged on the inner wall of the U-shaped accommodation block 112, the split elastic assembly 113 comprises an upper buffer 114 and a lower buffer 115, a first buffer inclined surface 116 is arranged at the connection between the upper end surface of the upper buffer 114 and the inner wall, an upper annular mounting groove 117 is formed in the lower end surface of the upper buffer 114, a second buffer inclined surface 118 is arranged at the connection between the lower end surface of the lower buffer 115 and the inner wall, an upper annular mounting groove 119 is formed in the upper end surface of the lower buffer 115, the upper annular mounting groove 117 and the lower annular mounting groove 119 cooperatively form a buffer cavity 120, and a spring piece 121 is arranged in the buffer cavity 120;

[0041] An upper abutting ring 122 and a lower abutting ring 123 are integrally formed on the outer wall of the connecting column 109, a first abutting inclined surface 124 is arranged on the outer wall of the upper abutting ring 122 and abuts and cooperates with the first buffer inclined surface 116, and a second abutting inclined surface 125 is arranged on the outer wall of the lower abutting ring 123 and abuts and cooperates with the second buffer inclined surface 118;

[0042] The transmission member drives the impeller 105 to rotate. The transmission structure is a general technology in the prior art, and details are not described herein. During rotation of the impeller 105, the connecting column 109 rotates around the impeller 105 in the U-shaped displacement block 112. The impeller 105 drives the connecting column 109, the spindle seat 108 and the sliding block 107, so that the sliding block 107 slides in the annular guide rail 106. During sliding of the sliding block 107 in the annular guide rail 106, the sliding block 107 rotates on the spindle seat 108 to adapt to the track of the annular guide rail 106. Through alignment of the displacement slots 111 on adjacent impellers 105, the walking spindle 104 is exchanged during high-speed rotation of the adjacent two impellers 105.

[0043] The upper and lower buffer members 115 cooperate with the first and second abutting inclined surfaces 125 of the connecting column 109 through the first and second buffer inclined surfaces 118, to convert the transverse impact force generated by high-speed movement of the walking spindle 104 into oblique and vertical components, reduce the horizontal impact strength, and further absorb residual vibration energy through elastic deformation of the spring piece 121 in the buffer chamber 120, to form a multi-stage damping effect and reduce transmission of vibration to the impeller 105.

[0044] The U-shaped displacement block 112 allows the split elastic assembly 113 to have controllable deformation when loaded, expands the buffer stroke, and provides a stable deformation space for the spring piece 121 to avoid fatigue fracture caused by stress concentration.

[0045] The first and second abutting inclined surfaces 125 of the connecting column 109 cooperate with the first and second buffer inclined surfaces 118 to form sliding guidance during movement, reduce the friction coefficient of the contact surface, and ensure smooth sliding of the walking spindle 104 in the U-shaped displacement block 112. The continuous elastic support of the spring piece 121 can adaptively compensate for the gap caused by machining errors or wear, to maintain transmission accuracy.

[0046] The multiple buffering effects in the displacement slot 111 can real-time offset the centrifugal force fluctuation when the connecting column 109 is transmitted between adjacent two impellers 105, avoid resonance phenomenon caused by high-speed rotation, thereby ensuring consistency of the weaving track, reducing the risk of broken line caused by vibration, and improving the yield rate.

[0047] Traditional rigid contact is easy to cause metal fatigue, and the split elastic assembly 113 converts instantaneous impact into slow-release energy through elastic deformation of the spring piece 121, significantly reduces the peak stress of the spindle seat 108, the connecting column 109 and other core components, and prolongs the service life.

[0048] The inclination angle of the first and second buffer inclined surfaces 118 optimizes the contact pressure distribution, avoids local excessive wear, and the rotational design of the spindle seat 108 reduces the direct effect of the torsional moment on the sliding block 107, to reduce the guide rail wear rate.

[0049] The upper and lower buffering members 115 can be independently replaced without replacing the elastic assembly as a whole, thereby reducing maintenance cost.

[0050] In the embodiment of the utility model, the inner wall of U type let -go piece 112 is equipped with T type installation groove 126, the outer wall of upper buffering member 114 is fixed with L type upper limiting piece 127, the outer wall of lower buffering member 115 is fixed with L type lower limiting piece 128, and upper limiting piece 127 and lower limiting piece 128 are respectively connected and limited in T type limiting groove,

[0051] The wide mouth of T type installation groove 126 is convenient for the preliminary alignment of upper and lower buffering members 115, and after the sliding of L type upper and lower limiting pieces 128 along the groove body, the precise clamping is formed in the groove, the installation deviation possibly generated by traditional bolt fixing is eliminated, the concentricity of upper and lower buffering members 115 is ensured, and the eccentric wear caused by misplacement of the elastic assembly is avoided;

[0052] The limiting cooperation of L type upper and lower limiting pieces 128 in T type groove not only limits the radial movement of split type elastic assembly 113 (ensures the stability of the working path of connecting column 109), but also allows the vertical elastic displacement of split type elastic assembly 113 to adapt to the elastic deformation requirement, so that the excessive constraint affecting the buffering performance is avoided;

[0053] The sliding clamping of L type limiting piece and T type groove is realized for the non-destructive disassembly of upper and lower buffering members 115, the replacement can be completed without special tools, the downtime maintenance time is significantly shortened, if a single buffering member is damaged (such as fatigue failure of upper buffering member 114), the corresponding replacement can be directly disassembled, the overall replacement of U type let -go piece 112 or split type elastic assembly 113 is not needed, and the spare part cost is saved;

[0054] The three surface adhesion (two sides and bottom surface) of L type upper and lower limiting pieces 128 and T type groove forms a three-dimensional constraint, prevents the radial escape or circumferential rotation of upper and lower buffering members 115 under high-speed vibration or impact load, and ensures that split type elastic assembly 113 is always in the preset working position.

[0055] In the embodiment of the utility model, first buffering plate 129 is arranged in T type installation groove 126, the outer side of first buffering plate 129 is in abutting cooperation with the inner wall of T type installation groove 126, and the inner side of first buffering plate 129 is in abutting cooperation with upper limiting piece 127 and lower limiting piece 128 respectively;

[0056] First buffering plate 129 is the intermediate buffering layer between T type installation groove 126 and upper and lower limiting pieces 128, absorbs the initial impact energy from connecting column 109 through the elastic deformation of itself, forms the three-stage buffering chain of "elastic piece 121-split type elastic assembly 113-first buffering plate 129", dissipates the vibration energy stage by stage, and significantly reduces the direct impact of peak load on the body of U type let -go piece 112;

[0057] The high-damping property of the first buffer plate 129 can effectively filter high-frequency micro-vibrations, such as vibrations caused by gear meshing noise of the impeller 105, to avoid transmission of the vibrations to the rack 100 through the T-shaped mounting groove 126, and improve equipment operation stability.

[0058] The first buffer plate 129 is in large-area contact with the inner wall of the T-shaped mounting groove 126, converts contact pressure originally concentrated on the edges of the upper and lower limit blocks 128 into a planar distribution, reduces local stress concentration, reduces the risk of micro-crack propagation of the inner wall of the T-shaped mounting groove 126, and prolongs the service life of the U-shaped limit block 112.

[0059] The elastic property of the first buffer plate 129 can form self-adaptive filling between the upper and lower limit blocks 128 and the T-shaped mounting groove 126, and compensate for the gap caused by machining tolerance or thermal deformation in real time, to prevent abnormal noise or impact vibration caused by looseness.

[0060] By selecting buffer plates with different hardness or thickness, equipment operation parameters can be flexibly matched, and the application range of the damping structure can be expanded.

[0061] In the embodiment of the utility model, the first buffer plate 129 includes first base layer 130, first buffer layer 131 and first contact layer 132 which are sequentially arranged from outside to inside, first base layer 130 is made of glass fiber reinforced engineering plastic, first buffer layer 131 is made of thermoplastic polyurethane and is formed into a corrugated structure on the surface of first base layer 130, and first contact layer 132 includes an ultra-high molecular weight polyethylene film covering the surface of first buffer layer 131.

[0062] The first base layer 130 made of glass fiber reinforced engineering plastic on the outside provides high-rigidity support, ensures stable contact with the inner wall of the T-shaped mounting groove 126, the middle TPU corrugated first buffer layer 131 absorbs high-frequency impact energy through elastic deformation, and the inside UHMWPE contact layer uses low-friction characteristics to smoothly transfer residual stress, forming a gradient buffer of "rigidity-elasticity-flexibility" and gradually weakening the vibration energy transmission efficiency.

[0063] In the embodiment of the utility model, the inner bottom surface of the L-shaped structure of the upper limit block 127 and the lower limit block 128 is respectively provided with a second buffer plate 136, a displacement cavity is pre-set between the second buffer plate 136 and the upper and lower limit blocks 128, the second buffer plate 136 includes a second base layer 137, a second buffer layer 138 and a second contact layer 139 which are sequentially arranged from bottom to top, the second base layer 137 is injection molded by hard plastic, the second buffer layer 138 is integrally formed with the second base layer, the second buffer layer 138 includes a plurality of wave-shaped protrusions, and the second contact layer 139 is arranged on the surface of the second buffer layer 138 and is provided with a rhombic grid texture.

[0064] The displacement cavity is arranged between the second buffer plate 136 and the upper and lower limiting blocks 128, so that when the upper and lower buffer members 114 and 115 drive the upper and lower limiting blocks 128 respectively, sufficient displacement distance can be ensured to adapt to the elastic deformation of the elastic sheet member 121, the second buffer plate 136 adopts a three-layer structure design, and the second buffer layer 138 comprises a plurality of wave-shaped protrusions, so that the structure can effectively disperse pressure when subjected to external force, and better buffering effect is provided,

[0065] The second base layer 137 is formed by hard plastic injection molding, so that the entire second buffer plate 136 has sufficient hardness and stability and is not easy to deform, the diamond grid texture on the second contact layer 139 not only increases the surface friction, but also improves the wear resistance of the contact surface, and prolongs the service life.

[0066] In the utility model embodiment, the inner wall of the yielding slot 111 is provided with a vertical positioning groove 143, and the outer wall of the U-shaped yielding block 112 is formed with a positioning block 144 which is limitedly inserted and matched in the positioning groove 143.

[0067] Through the close insertion and matching of the positioning block 144 and the positioning groove 143, the stability of the entire assembly structure is increased.

[0068] The requirement for the skill of workers is reduced, and the assembly time and cost are also reduced, since the positioning block 144 and the positioning groove 143 have the self-guiding characteristic, even in the case that the vision is poor or the operation space is limited, the assembly work can be successfully completed;

[0069] When maintenance or replacement of parts is needed, the cooperation mode of the positioning block 144 and the positioning groove 143 facilitates quick disassembly and reinstallation, without the need for complex tools or technology, and the efficiency and convenience of the maintenance work are improved.

[0070] In the utility model embodiment, the U-shaped yielding block 112 comprises an upper yielding block and a lower yielding block, the positioning block 144 is integrally formed on the outer wall of the lower yielding block, and a vertical guide sliding groove 145 is formed in the inner wall of the positioning block 144; the outer wall of the upper yielding block is formed with a guide sliding block 146 which is slidingly matched in the guide sliding groove 145.

[0071] Through the arrangement of the guide sliding groove 145 and the guide sliding block 146, the upper yielding block can be accurately slid into the lower yielding block in the vertical direction, so that the smooth movement and accurate positioning of the upper yielding block along the predetermined path are ensured, and the accuracy and stability of the overall assembly are improved.

[0072] The upper yielding block and the lower yielding block are accurately matched through the guide sliding groove 145 and the guide sliding block 146, which not only helps to resist the transverse force, but also facilitates the later replacement and maintenance of the split elastic assembly 113.

[0073] In the embodiment of the utility model, the elastic sheet piece 121 comprises a U-shaped wave-shaped elastic sheet 147;

[0074] The wave-shaped structure increases the effective deformation length of the elastic sheet, so that it can more effectively disperse and absorb energy when subjected to external force, and can significantly reduce the influence of external impact on the internal components of the product;

[0075] The wave-shaped design gives the elastic sheet a larger elastic deformation range. Compared with the traditional straight-line elastic sheet, it can bend to a greater extent without permanent deformation, ensuring good elastic recovery performance after long-term use and prolonging the service life of the product.

[0076] The U-shaped wave-shaped elastic sheet 147 realizes higher elasticity and strength in limited space through its unique shape design, which helps to optimize the spatial layout of the overall design, so that the product can improve performance without increasing the volume.

[0077] When the wave-shaped elastic sheet contacts other components, it can provide multiple contact points or surfaces due to its shape characteristics, increasing the contact area and improving the stability and reliability of the connection, reducing the problem of poor contact caused by vibration or other external factors.

[0078] In the embodiment of the utility model, the connection between the upper end face of the U-shaped accommodation block 112 and the inner wall is provided with a first inclined surface 148, and the connection between the lower end face of the U-shaped accommodation block 112 and the inner wall is provided with a second inclined surface 149.

[0079] The existence of the first inclined surface 148 and the second inclined surface 149 helps to disperse the stress concentrated on the edge of the U-shaped accommodation block 112, especially when subjected to external force, the inclined surface can help to more evenly distribute these forces, thereby reducing the risk of damage caused by local stress concentration and enhancing the stability and durability of the overall structure.

[0080] The inclined surface design increases the actual contact area with other components, which not only helps to improve the tightness of the contact, but also to a certain extent, compensates for manufacturing errors or installation deviations, ensures good contact between components, and avoids interference of the inner wall of the U-shaped accommodation block 112 with the elastic buffer of the upper buffer 114 and the lower buffer 115.

[0081] In the embodiment of the utility model, the number of accommodation grooves 111 on the impeller 105 can be flexibly adjusted according to actual production needs.

[0082] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than by the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.
