Description

Technical Field

[0001] This utility model relates to the field of servo motor repair technology, and in particular to an auxiliary tool for assembling actuator cylinder components. Background Technology

[0002] In hydraulic servo motors and other actuator components, the actuator cylinder assembly is frequently used. Its disassembly and assembly quality significantly impacts the performance of the servo motor. Furthermore, due to its high sealing requirements, extra care must be taken to protect it during repairs. The actuator cylinder assembly is a major component of the servo motor. Because most of its outer surface is a sealing mating surface, with a large sealing area and numerous rubber ring seals, it requires considerable installation force, making assembly difficult. Additionally, the irregularly shaped housing is difficult to place stably, making it challenging to install the assembly into the housing. Moreover, the actuator cylinder assembly's elongated cylindrical shape makes it impossible to guarantee the coaxiality of the cylinder and the housing bore during assembly, easily causing damage to the rubber rings.

[0003] According to the repair process requirements, the cylinder with the sealing ring must be slowly and evenly pushed into the housing while ensuring that the actuator assembly and the housing hole are coaxial. This facilitates operation, ensures installation quality, and prevents damage to the sealing ring. Therefore, it is necessary to design auxiliary tools for installing the actuator assembly based on the external structure of the actuator assembly and the housing assembly. This will facilitate fixing the housing assembly, ensure accurate application of installation force, and improve assembly efficiency and quality. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-9 An auxiliary tool for assembling an actuator cylinder assembly includes a base 1, a support plate 12 is mounted on one end of the base 1, a plurality of screws 4 are provided on the top of the support plate 12 to limit and fix the housing 5, and an auxiliary assembly mechanism for assisting the actuator cylinder assembly to be installed inside the housing 5 is mounted on the support plate 12.

[0026] As a technical optimization of this utility model, the auxiliary assembly mechanism includes a threaded rod 13, and a threaded hole 19 is provided inside the support plate 12. The threaded rod 13 is threadedly installed inside the threaded hole 19. The support plate 12 and the threaded hole 19 ensure that the direction of the applied force of the threaded rod 13 is consistent with the axial direction of the housing hole, thus solving the problem of difficulty in controlling the coaxiality of the actuator assembly and the housing hole. The diameter of the threaded rod 13 is adapted to the inner diameter of the threaded hole 19, and the axial displacement of the force-applying wheel 2 is transmitted through the threaded connection. The length of the threaded rod 13 is greater than the length of the piston rod 9 assembly.

[0027] As a technical optimization of this utility model, a fork head 3 is provided at one end of the threaded rod 13 above the base 1, and a force-applying wheel 2 is installed at the end of the threaded rod 13 away from the base 1. Since the threaded rod 13 is in a horizontal straight state inside the threaded hole 19, rotating the force-applying wheel 2 drives the horizontal threaded rod 13 to move slowly forward and backward inside the threaded hole 19, ensuring that the operator can slowly and uniformly apply a sufficiently large force to the actuator cylinder assembly, effectively reducing the rubber ring breakage rate.

[0028] As a technical optimization of this utility model, a connector is installed at one end of the threaded rod 13 above the base 1, and a connecting groove 20 is opened on the outer wall of the connector.

[0029] As a technical optimization of this utility model, the fork head 3 has an internal mounting hole 16. The fork head 3 is rotatably mounted to the connector via the internal mounting hole 16, and the inner wall of the mounting hole 16 is rotatably engaged with the outer wall of the connecting groove 20. Through the rotatable engagement of the mounting hole 16 and the connecting groove 20, the fork head 3 and the threaded rod 13 are rotatably connected. During the rotation of the driving force wheel 2, the threaded rod 13 is driven to move forward and backward inside the threaded hole 19, so that the fork head 3 remains in a state that is not easy to wobble. This allows the force applied by the force wheel 2 to be transmitted to the support 6 of the actuator cylinder assembly, preventing damage to other sealing surfaces of the actuator cylinder assembly.

[0030] As a technical optimization of this utility model, each of the multiple screws 4 is provided with a screw head 18 at one end, and the multiple screw heads 18 are threadedly connected to the multiple threaded connection holes opened on the top of the base 1.

[0031] In this embodiment, two lugs 14 are installed on both outer walls of the housing 5. Four screws 4, with one end of the screw head 18, are passed through the four lugs 14 of the housing 5 in sequence and then threaded into the multiple threaded connection holes on the top of the base 1. This fixes the housing 5 onto the base 1. The base 1 is relatively thick and can be directly clamped and fixed with a bench vise, thus fixing the housing 5. The screws 4 can quickly fix and remove the housing 5, solving the problem of the housing 5 being difficult to fix. The width of the base 1 should be greater than the maximum width between the lugs 14. The length, width, and diameter of the four threaded connection holes on the top of the base 1 for installing the screws 4 are consistent with the positions of the holes on the four lugs 14. The thread structure inside the four threaded connection holes can ensure the stable threaded installation between the screws 4 and the base 1. The length of the screws 4 is the same as the thickness of the housing 5, and the length of the screw head 18 is slightly greater than the sum of the thickness of the lugs 14 and the base 1, ensuring the fixed connection between the housing 5 and the base 1, while also facilitating disassembly and assembly.

[0032] The actuator assembly in this embodiment includes a sleeve 7, with multiple sealing rings 8 installed on the outer wall of the sleeve 7. A piston rod 9 is installed at one end of the sleeve 7, and a connecting rod 10 is installed at the end of the piston rod 9 away from the sleeve 7. A circular groove adapted to the actuator assembly is opened inside the housing 5. A support 6 is installed at the other end of the sleeve 7, and two brackets 15 are installed at the end of the support 6 away from the sleeve 7. Figure 8 As shown, four holes are provided inside the support 6. The positions of the four holes are matched with the positions of multiple studs 17 installed at one end of the housing 5 near the fork 3. After the actuator assembly is installed inside the housing 5, the multiple studs 17 pass through the corresponding holes. With the help of four additional fasteners threaded onto the surface of the corresponding studs 17, the actuator assembly installed inside the housing 5 can be limited and fixed.

[0033] A fork-shaped component 11 is installed inside the support 6, such as Figure 1 As shown, after the fork head 3 is inserted between the two brackets 15, when the force wheel 2 is manually rotated and tightened, the threaded rod 13 can slowly push the fork head 3 into the interior of the two brackets 15. Since the overall width of the fork head 3 is adapted to the width between the two brackets 15, after the fork head 3 enters between the two brackets 15, the fork head 3 can tightly abut against the outer wall of the side of the two brackets 15 that is close to each other, avoiding unstable factors such as shaking of the fork head 3 between the two brackets 15. Thus, as the threaded rod 13 continues to rotate, it can drive the fork head 3 to push the sleeve 7 into the interior of the housing 5 at a uniform speed, ensuring the coaxiality of the actuating cylinder assembly and the housing 5, and avoiding problems such as easy damage to the sealing ring during the installation of the sleeve 7.

[0034] In this utility model, when using the auxiliary tool, the base 1 is first clamped on the preset bench vise, with the clamping parts being the two sides of the base 1. The top of the base 1 is adjusted to be flush with the top of the vise, which ensures that the installation part of the housing 5 is above the vise. After the vise is tightened, it can be ensured that the auxiliary tool is stably clamped and fixed by the vise, waiting for the actuator assembly to be installed inside the housing 5 later.

[0035] Then, manually insert the actuating cylinder assembly with the rubber ring into the circular groove inside the housing 5 and push it in to ensure that the end of the sleeve 7 with the piston rod 9 enters the housing 5. Then, manually rotate the force wheel 2 in the opposite direction to drive the threaded rod 13 to move away from the base 1 to the maximum distance, so that the fork head 3 abuts against the support plate 12. Then, place the housing 5 together with the actuating cylinder assembly inside it on the top of the base 1 and fix it to the top of the base 1 with four screws 4.

[0036] Next, manually rotate the fork head 3 to ensure that the fork head 3 is in the correct position. Figure 1 As shown, the force-adding wheel 2 is rotated at a constant speed and slowly, which drives the end of the threaded rod 13 with the fork 3 installed to move slowly toward the direction of the housing 5. This causes the fork 3 to push the support 6 of the actuator cylinder assembly, which in turn pushes the entire actuator cylinder assembly to move slowly inside the housing 5 until the entire actuator cylinder assembly is installed inside the housing 5.

[0037] If the actuator assembly suddenly experiences increased resistance or other abnormalities during installation, it may be due to damage to the sealing ring 8 on the actuator assembly. The piston rod 9 should be disassembled and the actuator assembly reinstalled.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
