DETAILED DESCRIPTION

[0018] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Reference Figure 1 A piston seal assembly tool includes a guide member 50 sleeved on a piston member 60, a guide member 10 corresponding to the top of the piston member 60, and a seal member 20 sleeved on the outside of the guide member 50 and sliding along the guide member 50.

[0020] The guide member 50 is sleeved on the piston member 60, and its main function is to provide a guide and positioning reference for the seal 20, ensuring that the seal moves along the correct path during the assembly process to avoid offset or misalignment. The piston member 60 is the core component of the assembly tooling, and the annular adapter groove 61 on its outer side is used to adapt the seal 20 to ensure that the seal 20 can be correctly installed on the piston member 60. The pusher 10 corresponds to the top of the piston member 60, and through its structure, it pushes the seal 20 to slide along the guide member 50 and assemble to the piston member 60. The seal 20 is a key component in the assembly tooling, and needs to slide along the outside of the guide member 50 and finally be assembled to the piston member 60 to achieve the sealing function of the cylinder.

[0021] The cooperation of the guide member 50 and the piston member 60 provides accurate guidance and positioning for the seal 20, ensuring the accuracy of assembly. The push member 10, through its structural design, cooperates with the guide member 50 and the piston member 60 to push the seal 20 to slide along the guide member and assemble in place. The use of the elastic tension member 14 provides the necessary elastic force for the push arm 12, ensuring that the push block 13 can push the seal 20 evenly to avoid damage during the installation process.

[0022] In some embodiments, the piston member 60 is cylindrical, and an annular adapting groove 61 adapted to the sealing member 20 is formed on the outer side thereof.

[0023] The piston member 60 is a core component of the assembly tooling, and its cylindrical shape is conducive to a close fit with the seal 20. The cylindrical shape of the piston member 60 also helps to achieve uniform distribution and installation of the seal on the piston. The cylindrical design of the piston member 60 is to match the circular cross-section of the seal 20, ensuring that the seal 20 can fit tightly on the surface of the piston member 60, thereby providing a good sealing effect. An annular adapter groove 61 is provided on the outer side of the piston member 60, and its main function is to provide installation space and positioning for the seal 20, so that the seal 20 can be correctly installed on the piston member 60. The design of the adapter groove 61 is to adapt to the size and shape of the seal 20, ensuring that the seal 20 can expand evenly and fit tightly on the surface of the piston member 60 during the installation process.

[0024] The push member 10 cooperates with the guide member 50 through the push arm 12 and the push block 13 to push the sealing member 20 to slide along the guide member into the annular adapting groove 61 .

[0025] In some embodiments, the upper half of the guide member 50 is truncated cone-shaped, and the lower half is cylindrical.

[0026] The truncated cone-shaped upper portion of the guide member 50 provides a gradually tapering transition area, which helps guide the seal 20 to move smoothly along the surface of the guide member, reducing friction and wear. The truncated cone-shaped design allows the seal to have a gradual adaptation process during the assembly process, especially when the seal 20 needs to expand to adapt to the annular adapter groove 61 of the piston member 60, the truncated cone-shaped portion can serve as a transition to help the seal 20 smoothly enter the adapter groove. The cylindrical lower portion provides a stable guide and support base to ensure that the seal 20 maintains the correct direction and position during the assembly process. The cylindrical design increases the rigidity and stability of the guide member 50, so that the guide member 50 can provide uniform and consistent support when the push member 10 applies force to push the seal.

[0027] In some embodiments, the bottom of the lower half of the guide member 50 has a positioning hole 51 , and the inner side of the positioning hole 51 is adapted to the top outer contour of the piston member 60 .

[0028] The main function of the positioning hole 51 is to provide accurate positioning and support for the piston 60. By matching the outer contour of the top of the piston, the positioning hole 51 ensures that the piston maintains the correct position and direction during the assembly process. The matching design between the inner side of the positioning hole 51 and the top of the piston provides a fixed point so that the piston will not be displaced or rotated during the assembly process, thereby ensuring the accurate installation of the seal 20.

[0029] The entire assembly process relies on the precise fit and coordination of the various components. The positioning opening 51 ensures the position of the piston 60, the guide 50 provides guidance and support, and the pusher 10 applies a driving force, which together ensure that the seal 20 can be evenly and accurately assembled on the piston. This design principle improves the assembly efficiency and the installation quality of the seal by reducing the uncertainty and error in the assembly process.

[0030] In some embodiments, the derivation member 10 includes a docking seat 11 connected to the transmission device, and a plurality of derivation arms 12 hingedly disposed outside the docking seat 11 , and the derivation arms 12 extend downwardly over the docking seat 11 .

[0031] The docking seat 11 is an integral part of the derivation member 10, which plays the role of fixing and supporting the derivation arm 12, and is also the joint for connecting the derivation member 10 with the transmission device. The design of the docking seat 11 ensures the stability and accuracy of the derivation arm 12 when pushing the seal 20, and also enables the derivation member 10 to be stably connected to the transmission device. The derivation arm 12 is a component that directly contacts the seal 20 and pushes it to slide along the guide member 50. The derivation arm extends downward over the docking seat 11 and directly acts on the seal 20. The distance it crosses is used to adapt to the outer contour of the guide member 50 to avoid obstruction of the derivation arm 12 during the derivation process. The design of the derivation arm 12 enables them to evenly apply force to the seal 20, ensuring the smooth movement and correct positioning of the seal 20 during the assembly process.

[0032] The pusher 10 is connected to the transmission device through the docking seat 11, receiving power and transmitting it to the pusher arm 12. The pusher arm 12 is hinged on the docking seat 11. This design allows the pusher arm 12 to flexibly adapt to the truncated cone profile of the guide member 50 by rotation and accurately apply force to the seal 20. The pusher arm 12 extends downward over the docking seat 11, ensuring that they can directly contact the seal 20 and push the seal 20 along the path of the guide member 50. This design principle improves the speed and accuracy of assembly by using mechanical force instead of manual operation, while reducing human errors and possible damage to the seal 20 during assembly.

[0033] In some embodiments, a guide block 13 is provided on a side of the guide arm 12 away from the docking seat 11 . The guide block 13 is arc-shaped and is adapted to the outside of the guide member 50 .

[0034] The guide block 13 is a part of the guide arm 12, and its main function is to provide uniform force when the guide arm 12 pushes the seal 20. The arc design of the guide block 13 helps to adapt to the outer shape of the guide member 50, ensuring that the seal 20 moves smoothly along the path of the guide member 50 during the pushing process. The arc design of the guide block 13 enables it to match the outer shape of the guide member 50, thereby providing a continuous and uniform contact surface when pushing the seal 20, reducing friction and wear, and ensuring the stability and accuracy of the seal 20 during the assembly process. The guide block 13 is set on the side of the guide arm 12 away from the docking seat 11, which means that the guide block 13 is located at the end of the guide arm 12 and can directly act on the seal 20. The position design of the guide block 13 enables it to apply force to the seal 20 while maintaining adaptation to the guide member 50, which helps to control the direction and position of the seal 20 during the assembly process.

[0035] The guide block 13 is indirectly associated with the piston member 60 through the guide arm 12, because the movement of the guide arm 12 directly affects the assembly position of the seal 20 on the piston member. The guide block 13 directly acts on the seal 20, pushing it to slide along the guide member 50 until the seal is correctly assembled into the annular adapter groove 61 of the piston member 60.

[0036] In some embodiments, an elastic tensioning member 14 is sleeved on the exterior of the plurality of derivation arms 12 .

[0037] The main function of the elastic tensioner 14 is to provide the necessary elastic force when the derivation arm 12 pushes the seal 20, which helps to ensure that the derivation block 13 applies uniform and moderate force to the seal, avoiding damage to the seal due to excessive force, and also preventing the seal from being properly installed due to insufficient force. The elastic tensioner can absorb and release energy through its elastic characteristics, thereby providing a buffering and regulating effect when the derivation arm pushes the seal, ensuring uniform distribution and control of force. When the derivation arm 12 pushes the seal, the elastic tensioner 14 mounted on the outside will expand and contract as needed to adapt to the changes in the movement and assembly process of the seal. The elastic characteristics of the elastic tensioner enable the derivation arm to adapt to the position and state of the seal during the pushing process, thereby achieving a smoother and more precise push.

[0038] Some embodiments further include a fixing seat 40 , and a fixing shaft 41 extending into and fitting into the piston member 60 is disposed on the top of the fixing seat 40 .

[0039] The main function of the fixed seat 40 is to provide a stable support and fixing point for the entire assembly tooling. It ensures that during the assembly process, the piston member 60 and related components can be kept in the correct position to prevent displacement under the action of assembly forces. The design of the fixed seat 40 allows it to be securely mounted in an appropriate position, such as on a workbench or a special machine, to provide stable support for the piston member 60 and other components. The fixed shaft 41 is an extension of the top of the fixed seat 40, which is inserted into and adapted to the interior of the piston member 60 to fix and position the piston member. The design of the fixed shaft 41 allows it to adapt to the specific structure inside the piston member 60, ensuring that the piston member will not rotate or move during the assembly process, thereby maintaining the correct assembly position of the seal 20.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
