TECHNICAL FIELD
[0001] The utility model relates to rubber ring assembly field, especially a device for assembling rubber ring inside and outside fixed support and assembling rubber ring. BACKGROUND
[0002] In modern industrial production, rubber ring as a common sealing element, its assembly process is important to ensure the sealing performance of mechanical equipment. In the assembly of fixed support, workers usually use special tooling equipment to open the rubber seal ring, so as to install the fixed support smoothly. This process needs to be controlled accurately, because the physical properties of the rubber ring will change to some extent during the opening process, which may affect its performance.
[0003] Firstly, the tooling equipment needs to apply appropriate force and maintain a certain time when opening the rubber ring, so as to ensure that the rubber ring can be opened uniformly, avoiding the deformation of the rubber ring caused by excessive force or unevenness. Such deformation may cause the size of the rubber ring to change, affecting the fitting accuracy of the rubber ring and the fixed support, and thus affecting the sealing effect.
[0004] Secondly, the internal structure of the rubber ring may be damaged locally during the opening process due to continuous stretching. Such damage may be small, but in the long run, it may become a hidden danger for sealing performance. Therefore, special attention should be paid to the protection of the rubber ring during assembly to avoid unnecessary damage.
[0005] In addition, the material and hardness of the rubber ring also affect its performance during opening. Softer rubber ring may be more prone to deformation, while harder rubber ring may be more resistant to wear during assembly. Therefore, selecting the appropriate rubber ring material is also important to ensure the assembly quality and sealing performance.
[0006] Finally, in order to reduce the problems that may occur during the assembly of the rubber ring, some auxiliary measures can be taken, such as using lubricant to reduce friction, or using special tooling design to more evenly distribute the force when opening the rubber ring. These measures help to protect the rubber ring, prolong its service life, and ensure the long-term stable operation of the mechanical equipment.
[0007] In summary, there is an urgent need for a rubber ring assembly device with high efficiency and modular design. UTILITY MODEL CONTENTS

[0061] Embodiment two
[0062] The embodiment of the utility model further provides a device for assembling rubber ring, including the device for assembling rubber ring inner and outer fixed support as described in embodiment one, refer to Figure 2 、 Figure 3 and Figure 4 , further include outer support 6 and inner support 5, the inner wall of outer support 6 is equipped with rubber ring outer slot 61 along the extension of outer support 6 inner wall, the outer wall of inner support 5 is equipped with rubber ring inner slot 51 along the extension of inner support 5 outer wall, rubber ring outer slot 61 and rubber ring inner slot 51 are respectively adapted to resist the outer side and inner side of rubber ring 7. In a specific embodiment, the radius of rubber ring outer slot 61 and rubber ring inner slot 51 is same, and all is less than the diameter of rubber ring 7, and such design is because rubber ring 7 itself has certain deformation capacity, when assembling, rubber ring 7 will have certain deformation, and larger rubber ring 7 can fill rubber ring outer slot 61 and rubber ring inner slot 51 when deforming, so that the assembly strength between the three is improved.
[0063] The device for assembling rubber ring provided by the embodiment of the utility model, refer to Figure 2 and Figure 4 , the inner support placing groove 32 consistent with the extension direction of the inner support placing table 31 is equipped in the inner support placing table 31, generally speaking, the cross section shape of the inner support placing table 31 is annular, therefore the cross section shape of the inner support placing groove 32 is also annular, the bottom of the inner support 5 is equipped with the inner support lower protrusion 52 consistent with the extension direction of the inner support 5, and the cross section shape of the protrusion of the inner support 5 is also annular, and the inner support lower protrusion 52 and the inner support placing groove 32 are detachably connected. As an illustration, when the utility model is used, the inner support lower protrusion 52 is placed into the inner support placing groove 32, and the cooperation between the inner support placing groove 32 and the inner support lower protrusion 52 can make the inner support 5 not easy to separate from the profiling jig 3 when the profiling jig 3 deforms, and the safety of the utility model during use is improved.
[0064] The device for assembling rubber ring provided by the embodiment of the utility model, refer to Figure 4The top of the inner support 5 is provided with an inner support upper protrusion 53 consistent with the extension direction of the inner support 5, and the inner support upper protrusion 53 is symmetrical with the inner support lower protrusion 52. As an illustration, the symmetry of the inner support upper protrusion 53 and the inner support lower protrusion 52 can ensure the stability of the inner support 5, so that the center of gravity of the inner support 5 is not offset due to the inner support lower protrusion 52, and the safety of the utility model in use is improved.
[0065] In a specific embodiment, referring to Figure 2 The width of the inner support placing groove 32 is greater than the width of the inner support lower protrusion 52. In another specific embodiment, the inner diameter of the inner support 5 is greater than the diameter of the jig upper portion 34. Generally, the above two embodiments can be used in the same embodiment. The design advantage of the above two embodiments is that when the profiling jig 3 is extruded, the jig upper portion 34 will deform outwardly and downwardly. If the profiling jig 3 is attached to the inner wall of the inner support 5 in the initial state, the profiling jig 3 is likely to extrude and break the inner support 5 when deformed, thereby causing the inner support 5 to break. Therefore, the design of the above two embodiments can ensure that the profiling jig 3 has sufficient space when deformed, thereby improving the safety of the utility model in use.
[0066] The above is only the preferred embodiment of the utility model, and it should be pointed out that for ordinary skilled persons in the technical field, several improvements and substitutions can be made without departing from the technical principles of the utility model, and these improvements and substitutions should also be considered as the protection range of the utility model.
