[0008] In one embodiment, the abutment portion is provided with an abutment groove for installing the sealing ring to be assembled.

[0009] In one embodiment, the push block is movable relative to the base and has an initial position, in which the space defined by the plurality of abutment components mounted on the base is not larger than the inner diameter of the sealing ring to be assembled.

[0010] In one embodiment, the abutment assembly further includes a reset assembly, and the reset assembly includes a first mounting block provided on the base and a first reset member provided on the first mounting block; at the abutment position, the first reset member and the first mounting block compress the first reset member; The resetting assembly further includes a second mounting block disposed on the base and a second resetting member disposed on the second mounting block; at the abutting position, the second resetting member and the second mounting block compress the second resetting member.

Since the abutment components are slidably connected, they can move when subjected to thrust, thereby changing the relative position between them. When the plurality of abutment components are pushed and translated by the push block, they will act together on the inner side of the sealing ring to be assembled, so that the inner diameter of the sealing ring is expanded. The principle of the expansion of the inner diameter of the sealing ring is that the movement of the abutment components will cause the contact points between them and the inner side of the sealing ring to change, thereby forming an outward expansion force. While the inner diameter of the sealing ring is expanded, the pressing ring mechanism pushes the edge of the sealing ring from top to bottom. This force will cause the sealing ring to detach from the abutment component and smoothly fall into the sealing groove of the corresponding part. Compared with the manual method, this solution uses a sealing ring assembly machine to significantly reduce the time and labor costs during the installation process. The machine can automatically complete the inner diameter expansion and installation process without frequent human involvement, thereby improving work efficiency; secondly, since the machine can automatically complete most of the work, workers only need to perform simple operations and monitoring, which greatly reduces labor intensity; secondly, mechanized production usually has higher precision and consistency, so the use of a sealing ring assembly machine can ensure that each sealing ring is correctly installed in the sealing groove of the corresponding part, thereby improving product quality; secondly, since manual operations are reduced, the possibility of errors is also reduced. The machine can work according to preset procedures and parameters, avoiding errors caused by human factors. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Sealing rings need to be installed on certain parts. Currently, rectangular sealing rings are usually installed manually. During the installation process, the rectangular sealing rings need to be pressed into the sealing grooves of the corresponding parts to be assembled. The installation process is time-consuming and labor-intensive, with low work efficiency. The manufacturing process requires frequent participation of workers, which not only increases labor intensity, but also increases costs and the probability of errors, making product quality more difficult to control.

[0026] In order to solve the above-mentioned problems such as low assembly efficiency.

[0027] Reference Figures 1 to 6 The sealing ring assembly machine includes a frame 100, a base 200 installed on the frame 100, a stop mechanism 300 and a pressing ring mechanism 600 both arranged on the base 200, the stop mechanism 300 includes a push block 500 which is slidably connected with the base 200 and abuts against a plurality of abutting components 400, and can move up and down relative to the base 200, the push block 500 has an abutting position, at which the push block 500 abuts against the plurality of abutting components 400, so that the plurality of abutting components 400 are translated relative to the edge of the base 200, so that the inner diameter of the sealing ring 700 to be assembled abutted by the plurality of abutting components 400 is expanded; the pressing ring mechanism 600 is arranged on the base 200, and the pressing ring mechanism 600 can push the edge of the sealing ring 700 to be assembled from top to bottom at the abutting position, so that the sealing ring 700 to be assembled is separated from the plurality of abutting components 400.

[0028] The technical solution of the present invention realizes the expansion of the inner diameter of the sealing ring during the installation process through the design of the stop mechanism 300, and successfully installs it on the corresponding parts. Specifically, the stop mechanism 300 includes a plurality of abutment components 400 slidably connected to the base 200 and a push block 500 that can move up and down relative to the base 200. When the push block 500 is in the abutment position, it will abut against the plurality of abutment components 400, pushing these abutment components 400 to translate relative to the edge of the base 200. Since the abutment components 400 are slidably connected, they can move when they are subjected to thrust, thereby changing the relative position between them. When the plurality of abutment components 400 are pushed and translated by the push block 500, they will act together on the inner side of the sealing ring 700 to be assembled, so that the inner diameter of the sealing ring is expanded. The principle of the expansion of the inner diameter of the sealing ring is that the movement of the abutment components 400 will cause the contact points between them and the inner side of the sealing ring to change, thereby forming an outward expansion force. While the inner diameter of the sealing ring is expanded, the pressing ring mechanism 600 pushes the edge of the sealing ring from top to bottom. This force will cause the sealing ring to detach from the abutment assembly 400 and smoothly fall into the sealing groove of the corresponding part. Compared with the effect of the manual method, the use of a sealing ring assembly machine in this solution can significantly reduce the time and labor costs during the installation process. The machine can automatically complete the inner diameter expansion and installation process without frequent human involvement, thereby improving work efficiency; secondly, since the machine can automatically complete most of the work, workers only need to perform simple operations and monitoring, which greatly reduces labor intensity; secondly, mechanized production usually has higher precision and consistency, so the use of a sealing ring assembly machine can ensure that each sealing ring is correctly installed in the sealing groove of the corresponding part, thereby improving product quality; secondly, since manual operation is reduced, the possibility of errors is also reduced. The machine can work according to preset procedures and parameters, avoiding errors caused by human factors.

[0029] In one embodiment, the frame 100 is a fixed frame 100. In this embodiment, if the base 200 cannot move relative to the frame 100, then when in use, the sealing ring 700 to be assembled can be first installed on the multiple abutment components 400, and then the push block 500 drives the multiple abutment components 400 to move to expand the inner diameter of the sealing ring 700 to be assembled; after placing the opponent part at the corresponding position, the pressing ring mechanism 600 installs the sealing ring 700 to be assembled on the opponent part.

[0030] Reference Figure 1 and Figure 2 In this embodiment, a transverse movement mechanism 130 is provided on the frame 100, and the transverse movement mechanism 130 drives the base 200 to move left and right. In this way, the sealing ring assembly machine can take or put down the sealing ring 700 to be assembled at different horizontal positions, which can adapt to more usage scenarios.

[0031] Specifically, the transverse movement mechanism 130 includes a straight-moving guide rail and a straight-moving slider assembled on the straight-moving guide rail; the base 200 is directly or indirectly connected to the straight-moving slider.

[0032] Reference Figures 3 to 6 , first introduce the relevant content of the resistance mechanism 300.

[0033] Regarding the transmission method of the push block 500 and the plurality of abutment components 400 .

[0034] In one embodiment, the push block 500 moves up and down relative to the base 200 and is transmission-connected with the plurality of abutment components 400 (the transmission connection may be implemented in any manner achievable in the prior art), thereby driving the plurality of abutment components 400 to translate away from the edge of the base 200 or close to the edge of the base 200; when the plurality of abutment components 400 are driven to expand by the push block 500, the assembly sealing rings installed on the plurality of abutment components 400 will be stretched open, because the inner diameter of the sealing ring 700 to be assembled is expanded, and the sealing ring 700 to be assembled is moved to the opponent part 800, and then the pressing ring mechanism 600 pushes the edge of the sealing ring 700 to be assembled, so that the sealing ring 700 to be assembled can be installed on the opponent part 800.

[0035] Combined with reference Figure 6 In this embodiment, the push block 500 cooperates with the inclined surface of the abutment part of the abutment assembly 400. The push block 500 can be moved up and down relative to the base 200 through a manipulator or other transmission mechanism installed on the frame 100, thereby driving the movement of multiple abutment assemblies 400 to achieve the purpose of expanding the inner diameter of the sealing ring 700 to be assembled.

[0036] Bevel fit refers to a fit method in which two parts have an inclined angle on the contact surface. In this example, the contact surface between the push block 500 and the abutment assembly 400 is designed to be a bevel, so that when the push block 500 moves up and down, its bevel can slide relative to the bevel of the abutment assembly 400, and transmit the change of force and direction through this sliding. Bevel fit can ensure that the push block 500 can smoothly transfer force to the abutment assembly 400 when it moves up and down. In the process of expanding the inner diameter of the sealing ring, the abutment assembly 400 needs to deform to a certain extent to adapt to the shape change of the sealing ring. Bevel fit can allow the abutment assembly 400 to deform appropriately when it is subjected to thrust, thereby ensuring that the sealing ring can be evenly expanded and avoiding damage to the sealing ring or installation failure due to uneven deformation.

[0037] Reference Figure 3Specifically, the stop mechanism 300 also includes a first moving mechanism 350, including a first mounting plate 352 connected to a first cylinder 351 and a transmission shaft of the first cylinder 351, and a push block 500 is arranged on the first mounting plate 352. The first mounting plate 352 is driven by the first cylinder 351, and the push block 500 can move up and down relative to the base 200. The main purpose of setting the first moving mechanism 350 is to achieve accurate up and down movement of the push block 500, thereby driving the abutment member in the abutment assembly 400 to translate, so as to achieve accurate control of the inner diameter of the sealing ring. Through the telescopic movement of the first cylinder 351, the first mounting plate 352 connected to the transmission shaft can be driven to move up and down, thereby pushing the push block 500 to move up and down relative to the base 200. The structure of the first moving mechanism 350 is relatively simple, mainly consisting of a cylinder, a transmission shaft and a first mounting plate 352, so it is easy to maintain and service. This helps to extend the service life of the equipment and reduce maintenance costs.

[0038] In other embodiments, the first moving mechanism 350 may also be driven by a motor.

[0039] Reference Figures 3 to 6 , regarding the composition of multiple abutment components 400.

[0040] Reference Figure 6 Specifically, the base 200 is provided with an avoidance groove, and the push block 500 is provided with multiple push blocks 500, and the multiple push blocks 500 are movably provided with the avoidance groove, and the multiple push blocks 500 correspond to the multiple abutment components 400 one by one. By equipping each abutment component 400 with a corresponding push block 500, it can be ensured that each abutment component 400 can be subjected to a uniform and controllable thrust. This helps to achieve the precise expansion of the inner diameter of the sealing ring and avoid the deformation or damage of the sealing ring caused by uneven thrust. Multiple push blocks 500 work simultaneously, which can significantly shorten the time for the inner diameter of the sealing ring to expand, thereby improving the efficiency of the entire assembly process. By adjusting the number and layout of the push blocks 500 and the abutment components 400, it can adapt to sealing rings of different sizes and shapes, and improve the versatility and flexibility of the machine; for example, circular, rectangular, prismatic or other shaped sealing rings, that is, in a circular sealing ring, the abutment component 400 can be two semicircular abutment sliders; in a rectangular solution, it can be two half-frame abutment sliders.

[0041] Specifically, in this embodiment, in order to install a rectangular sealing ring with concave arcs at the corners, the base 200 is rectangular, and a plurality of abutment assemblies 400 are respectively arranged at the four corners of the base 200. The abutment assemblies 400 include a first abutment member 310 that is respectively movable in the length direction of the base 200 and a second abutment member 320 that is respectively movable in the width direction of the base 200; wherein, in the abutment position, the first abutment member 310 and the second abutment member 320 on the opposite sides of the base 200 move in opposite directions.

[0042] The main purpose of setting the abutment assembly 400 as the first abutment member 310 and the second abutment member 320 is to achieve multi-directional and precisely controlled expansion of the inner diameter of the sealing ring 700 to be assembled. The first abutment member 310 and the second abutment member 320 are translated along the length and width directions of the base 200 respectively, so as to ensure that the sealing ring can be subjected to uniform and controllable expansion force in both the horizontal and vertical directions, thereby avoiding deformation or damage of the sealing ring due to uneven force distribution. Since the first abutment member 310 and the second abutment member 320 move along the two main directions of the base 200 respectively, the deformation process of the sealing ring can be more effectively controlled and the assembly error can be reduced.

[0043] The abutment portion 330 is provided with an abutment groove 331 for installing the sealing ring 700 to be assembled; the push block 500 can move relative to the base 200 and have an initial position. In the initial position, the space defined by the multiple abutment components 400 installed on the base 200 is not larger than the inner diameter of the sealing ring 700 to be assembled, so that it is convenient to place the sealing ring between the multiple abutment components 400 at the initial position, thereby facilitating subsequent operations.

[0044] The main purpose of providing the abutment groove 331 in the abutment portion 330 is to provide a stable support surface so that the sealing ring can be firmly grasped during the process of the inner diameter of the sealing ring expanding to prevent it from slipping or deforming. The shape and size of the abutment groove 331 can be designed according to the specifications of the sealing ring to ensure the best matching effect.

[0045] Reference Figure 4 and Figure 6 Specifically, the abutting assembly 400 further includes a reset assembly 340, which includes a first mounting block 341 provided on the base 200 and a first reset member 342 provided on the first mounting block 341; in the abutting position, the first reset member 342 and the first mounting block 341 compress the first reset member 342; the reset assembly 340 further includes a second mounting block 343 provided on the base 200 and a second reset member 344 provided on the second mounting block 343; in the abutting position, the second reset member 344 and the second mounting block 343 compress the second reset member 344. The reset assembly 340 can ensure that after the sealing ring is assembled, the abutting assembly 400 can automatically return to the initial position to prepare for the next assembly, which avoids the tediousness and errors caused by manual reset and can improve the assembly efficiency of the sealing ring assembly machine. In addition, the structure of the reset assembly 340 is relatively simple and easy to maintain and replace. This reduces the maintenance cost of the machine and prolongs its service life.

[0046] Regarding the connection method between the stop mechanism 300 and the base 200.

[0047] Reference Figures 1 to 3The sealing ring assembly machine also includes a second moving mechanism 110 and a connecting base plate 120. The second moving mechanism 110 includes a second cylinder 111 and a second mounting plate 112 connected to the transmission shaft of the second cylinder 111; the connecting base plate 120 is connected to the base 200 and to the second mounting plate 112; wherein, by driving the second mounting plate 112 through the second cylinder 111, the connecting base plate 120 can drive the base 200 to approach or move away from the push block 500.

[0048] In one embodiment, the second moving mechanism 110 drives the base 200 to move closer to or away from the push block 500, so that the push block 500 can cooperate with the multiple abutment components 400 to achieve the purpose of expanding the inner diameter of the sealing ring 700 to be assembled abutted by the multiple abutment components 400.

[0049] In this embodiment, the first cylinder 351 of the first moving mechanism 350 is installed on the connecting substrate 120, and the second cylinder 111 can drive the connecting substrate 120 to move up and down relative to the frame 100, so that the stopping mechanism 300 is close to or away from the material table under the frame 100, so as to facilitate operations such as taking or placing materials; and the first cylinder 351 can make the push block 500 close to the multiple abutment components 400, so that the multiple abutment components 400 can be translated relative to the edge of the base 200, so that the inner diameter of the sealing ring 700 to be assembled against which the multiple abutment components 400 are abutted can be expanded.

[0050] In addition, in combination with the transverse movement mechanism 130 provided on the frame 100 mentioned above, the sealing ring assembly machine can automatically realize the material picking and discharging process of the sealing ring in transverse and vertical movement; that is, the sealing ring assembly machine is provided with the transverse movement mechanism 130, the first moving mechanism 350 and the second moving mechanism 110 on the frame 100 to realize multi-directional and precise control during the sealing ring assembly process. These mechanisms work together to ensure that the sealing ring can be accurately installed in the sealing groove of the corresponding part, while improving assembly efficiency and stability.

[0051] Combined with reference Figure 4 , regarding the structure of the pressing ring mechanism 600.

[0052] In this embodiment, the pressing ring mechanism 600 includes a plurality of pressing ring assemblies 610, and the pressing ring assemblies 610 include a fixed seat 611, an air pump 612 installed on the fixed seat 611 and a pressing block 613 connected to the air pump 612 by transmission, and two guide rods 614 arranged at both ends of the pressing block 613, and an elastic reset member 615 is arranged between the guide rod 614 and the fixed seat 611. The pressing block 613 is driven by the air pump 612 to perform the pressing ring operation, and the guide rod 614 and the elastic reset member 615 are used to ensure that the pressing block 613 can be accurately and stably pressed at the desired position to achieve precise pressing ring. The setting of the elastic reset member 615 can play a buffering role when the pressing block 613 is pressed, protecting the pressed parts from damage caused by excessive pressure. The air pump 612 drives the pressing block 613 to perform a fast and stable pressing ring operation, which can significantly improve the efficiency of the pressing ring and shorten the production cycle.

[0053] Specifically, the elastic reset member 615 is a compression spring; each guide rod 614 is provided with one.
