Description

Technical Field

[0001] This utility model relates to the field of electro-hydraulic push rod processing technology, specifically to an electro-hydraulic push rod sealing ring quick pressing device. Background Technology

[0002] An electro-hydraulic actuator is a device that converts electrical energy into hydraulic energy, and then into linear mechanical motion. It is widely used in industrial automation, engineering machinery, medical equipment and other fields. When machining an electro-hydraulic actuator, a sealing ring needs to be press-fitted onto the outer wall of its piston.

[0003] The "Hydraulic Cylinder Elastic Seal Ring Installation Device" disclosed in publication number "CN221248505U" includes a device body and a manipulator mounted on the device body. An operating platform is fixedly connected to the upper outer wall of the device body. Movable grooves are provided on both sides of the operating platform, and connecting parts are slidably connected to the inner sidewall of the movable groove.

[0004] Traditional equipment typically installs sealing rings on the piston of a hydraulic push rod by pressing. This pressing method can lead to deformation of the sealing ring during operation if it's not fully aligned with the piston. A deformed sealing ring reduces the sealing performance of the hydraulic push rod piston, resulting in decreased hydraulic push rod performance. Furthermore, installing a second sealing ring requires manual rotation of the piston, increasing workload and potentially causing positional misalignment, making it impossible to install the second sealing ring later. Therefore, we have designed an electric hydraulic push rod sealing ring quick-pressing device to solve these problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a rapid pressing device for electric hydraulic push rod seal rings, which solves the problem that the seal ring may deform during operation due to incomplete alignment with the piston when pressing, and the problem that the piston of the hydraulic push rod needs to be manually rotated by the operator when installing the second seal ring.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an electric hydraulic push rod sealing ring quick pressing device, including an assembly table and an assembly seat mounted on the assembly table;

[0007] A fixed frame is fixedly installed at the bottom of the assembly table, and a first push rod is fixedly installed at the bottom of the fixed frame. The output end of the first push rod passes through the fixed frame and is fixedly installed with a lifting platform. Fixed plates are fixedly installed on both sides of the top of the assembly table. A fourth push rod is rotatably installed inside each fixed plate through a rotating ring. A clamping ring is fixedly installed at the output end of each fourth push rod. An adjusting motor is fixedly installed on the outer side of each fixed plate. The output end of the adjusting motor extends into the interior of the fixed plate and is fixedly installed with a gear shaft. A gear ring that mates with the gear shaft is fixedly installed on the outer wall of the rotating ring.

[0008] A threaded ring is slidably installed at the center of the assembly base. A third push rod is fixedly installed at equal intervals on the outer wall of the threaded ring. An assembly ring is fixedly installed at the output end of each third push rod. A positioning groove is opened at the bottom of each assembly ring. A push ring that cooperates with the assembly ring is fixedly installed on the outer side of the bottom of the assembly base.

[0009] Preferably, a drive motor is fixedly installed above the center position inside the assembly base, and a threaded rod that is threadedly connected to the threaded ring is fixedly installed at the output end of the drive motor.

[0010] Preferably, a limit post is fixedly installed at the center of the top of the lifting platform.

[0011] Preferably, the inner wall of each clamping ring is fixedly fitted with a flexible rubber pad, and the inner side of each flexible rubber pad is provided with an anti-slip groove.

[0012] Preferably, a second push rod is fixedly installed on the top of the assembly table via a support frame, and an installation plate connected to the top of the assembly base is fixedly installed on the output end of the second push rod.

[0013] Preferably, leg supports are fixedly installed on both sides of the bottom of the assembly table, and leg plates are fixedly installed on the bottom of each leg support.

[0014] This utility model provides a rapid pressing device for electro-hydraulic push rod seal rings. Compared with the prior art, it has the following advantages:

[0015] Beneficial effects:

[0016] (1) The electric hydraulic push rod sealing ring quick pressing equipment can elastically expand the sealing ring through the cooperation between the fourth push rod and the clamping ring, so that the sealing ring can be installed on the outer wall of the piston of the hydraulic push rod by means of expansion, avoiding the situation of the sealing ring being squeezed and deformed during pressing installation, and increasing the stability of the equipment when installing the sealing ring on the hydraulic push rod piston.

[0017] (2) By cooperating with the fourth push rod, clamping ring and rotating ring, the hydraulic push rod piston after the seal ring is installed can be flipped. The flipping of the hydraulic push rod piston facilitates the installation of its second seal ring, which increases the functionality of the equipment and improves the efficiency of installing the seal ring on the hydraulic push rod piston.

[0025] 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 scope of protection of the present utility model.

[0026] Example 1

[0027] Please see Figure 1-3As shown, this embodiment proposes a rapid pressing device for an electro-hydraulic push rod sealing ring, including an assembly table 1 and an assembly base 4 mounted on the assembly table 1. A fixing frame 103 is fixedly installed at the bottom of the assembly table 1, and a first push rod 2 is fixedly installed at the bottom of the fixing frame 103. The output end of the first push rod 2 passes through the fixing frame 103 and is fixedly installed with a lifting platform 201. Fixing plates 104 are fixedly installed on both sides of the top of the assembly table 1. A fourth push rod 5 is rotatably installed inside the fixing plate 104 through a rotating ring 503. A clamping ring 501 is fixedly installed at the output end of the fourth push rod 5. An adjusting motor 505 is fixedly installed on the outer side of the fixing plate 104. The output end of the adjusting motor 505 extends into the interior of the fixing plate 104 and is fixedly installed with a gear shaft 506. A gear ring 504 that cooperates with the gear shaft 506 is fixedly installed on the outer wall of the rotating ring 503.

[0028] In use, the operator can place the hydraulic push rod piston with the sealing ring to be installed on the lifting platform 201, facilitating the installation of the sealing ring on the outer wall of the piston placed on the lifting platform 201. After the first sealing ring on the piston is installed, the fourth push rod 5 extends to move the clamping ring 501, clamping the clamping ring 501 onto the outer wall of the piston. After both sets of clamping rings 501 are clamped onto the outer wall of the piston, the first push rod 2 installed on the fixing frame 103 retracts to lower the lifting platform 201. After the lifting platform 201 descends... The gear shaft 506 at the output end of the adjusting motor 505 meshes with the gear ring 504 on the outer wall of the rotating ring 503. Thus, by adjusting the motor 505, the rotating ring 503 and the piston inside the clamping ring 501 can be automatically rotated. The rotation of the piston facilitates the installation of its second sealing ring, avoiding the need for manual rotation by the operator, which increases the workload and prevents positional deviations after manual rotation. This increases the accuracy of the equipment when installing the second sealing ring of the piston.

[0029] Example 2

[0030] Based on Example 1, such as Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, a threaded ring 405 is slidably installed at the center of the assembly base 4. A third push rod 404 is fixedly installed at equal intervals on the outer wall of the threaded ring 405. An assembly ring 402 is fixedly installed at the output end of each of the third push rods 404. A positioning groove 403 is opened at the bottom of the outer wall of the assembly ring 402. A push ring 401 that works with the assembly ring 402 is fixedly installed on the outer side of the bottom of the assembly base 4.

[0031] In use, the mounting base 4 is mounted directly above the lifting platform 201. The third push rod 404 inside the mounting base 4 can retract to retract the mounting ring 402. After the mounting ring 402 retracts, it is convenient for the operator to place the sealing ring onto its outer wall. The positioning groove 403 on the outer wall of the mounting ring 402 can position the placed sealing ring. After the sealing ring is placed on the mounting ring 402, the third push rod 404 extends, causing the mounting ring 402 to expand outward again, thus allowing the sealing ring to expand elastically. After the sealing ring expands elastically, the mounting base 4 is lowered. When the threaded ring 405 moves upward to the outside of the piston, it can drive the third push rod 404 and the assembly ring 402 to move upward synchronously. When the assembly ring 402 moves upward, the sealing ring on its outer wall will push the ring 401 to remain stationary. When the assembly ring 402 is completely retracted into the inside of the assembly seat 4, the sealing ring will fall into the outer wall of the piston, thus installing the sealing ring on the outer wall of the piston. The outward expansion installation method of the sealing ring can avoid deformation during operation, improve the stability of the equipment when installing the sealing ring on the piston, and ensure the sealing performance of the piston in subsequent use.

[0032] like Figure 5 As shown, a drive motor 407 is fixedly installed above the center position inside the mounting base 4, and a threaded rod 406 that is threadedly connected to the threaded ring 405 is fixedly installed at the output end of the drive motor 407.

[0033] In use, the drive motor 407 can drive the threaded rod 406 to rotate. When the threaded rod 406 rotates, it can adjust the threaded ring 405 to move up or down, so that the sealing ring can be installed on the outer wall of the piston by electric means.

[0034] like Figure 2 As shown, a limit post 202 is fixedly installed at the center of the top of the lifting platform 201.

[0035] When in use, the limiting post 202 can limit the piston when it is placed on top of the lifting platform 201, thereby ensuring the accuracy of the equipment when installing the sealing ring on the piston and improving the installation quality during equipment operation.

[0036] like Figure 2-3 As shown, flexible rubber pads 502 are fixedly installed on the inner wall of the clamping ring 501, and anti-slip grooves are opened on the inner side of the flexible rubber pads 502.

[0037] In use, the flexible rubber pad 502 can provide flexible protection when the clamping ring 501 clamps the outer wall of the piston, avoiding scratches on the outer wall of the piston caused by the clamping ring 501. The anti-slip groove increases the friction of the flexible rubber pad 502 and improves the stability of the clamping ring 501 when clamping and flipping the piston.

[0038] like Figure 1and Figure 4 As shown, a second push rod 3 is fixedly installed on the top of the assembly table 1 via a support frame 105, and an installation plate 301 connected to the top of the assembly base 4 is fixedly installed at the output end of the second push rod 3.

[0039] In use, the second push rod 3 is fixedly installed above the assembly table 1 via the support frame 105. The mounting plate 301 at the output end of the second push rod 3 is fixedly connected to the top of the assembly base 4, so that the height of the assembly base 4 during operation can be adjusted and controlled by the second push rod 3.

[0040] like Figure 1 As shown, leg supports 101 are fixedly installed on both sides of the bottom of the assembly table 1, and leg plates 102 are fixedly installed on the bottom of each leg support 101.

[0041] In use, the leg support 101 can support the bottom of the assembly table 1 during operation, and the leg plate 102 can be fixed to the bottom of the leg support 101 with bolts. The fixation of the leg plate 102 ensures the stability of the leg support 101 when supporting the assembly table 1.

[0042] Working principle: The piston to be fitted with the sealing ring is placed on the lifting platform 201. The limiting post 202 can position the piston during placement. The operator manually places the sealing ring onto the outer wall of the contracted assembly ring 402. The third push rod 404 can expand the assembly ring 402 and the sealing ring by extending, thereby allowing the sealing ring to stretch elastically. The second push rod 3 can lower the assembly seat 4 and the sealing ring, which has been elastically expanded by the assembly ring 402, to the outside of the piston by extending. The drive motor 407 drives the threaded rod 406 to rotate, which can raise the threaded ring 405, the third push rod 404, and the assembly ring 402. After the assembly ring 402 rises, the sealing ring falls into the outer wall of the piston due to the contact of the push ring 401. This allows the sealing ring to be installed on the outside of the piston through elastic expansion, avoiding deformation of the sealing ring during pressure installation. After the first sealing ring is installed on the piston, the fourth push rod 5 extends to clamp and fix the outer wall of the piston with the clamping ring 501. Meanwhile, the first push rod 2 retracts, causing the lifting platform 201 to descend. The adjusting motor 505 can drive the rotating ring 503 to rotate through the gear shaft 506 and gear ring 504, thereby flipping the piston after one sealing ring is installed. Flipping the piston facilitates the installation of the second sealing ring, increasing the functionality of the equipment and ensuring stability during the installation of the second sealing ring.
