Description

Technical Field

[0001] This utility model relates to the field of hydraulic actuator technology, specifically to a lightweight hydraulic actuator assembly. Background Technology

[0002] A lightweight hydraulic actuator is a drive device powered by hydraulic oil. A hydraulic pump draws hydraulic oil from the tank and delivers it to the hydraulic cylinder. The piston inside the cylinder moves under the pressure of the hydraulic oil, thus achieving linear or rotary motion and driving the connected mechanical parts. By controlling the flow of hydraulic oil through a solenoid valve, the direction and speed of piston movement can be changed, achieving precise control of the actuator. The hydraulic actuator receives pressurized oil from an external hydraulic system or its own integrated hydraulic power source. Utilizing the incompressible property of liquids, hydraulic energy is converted into mechanical energy to drive the valve core or valve plate of valves and other equipment, thereby controlling the fluid medium.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology:

[0004] Traditional lightweight hydraulic actuator assemblies are often fixed with multiple screws when connected to valves and other equipment. When maintenance is required, these screws must be removed one by one, which is time-consuming and labor-intensive. Utility Model Content

[0026] Mounting component 3 includes mounting ring 301, and the top of mounting ring 301 has a circular groove 302, a rectangular groove 303 and a screw hole 304.

[0027] The fixing component 4 includes a fixing block 401 welded to the outer wall of the mounting ring 301. A fixing cylinder 402 is installed on one side of the fixing block 401. A plug rod 403 is slidably installed through one side of the fixing block 401. A limit block 404 is installed on the outer wall of the plug rod 403. A pull rod 405 is installed at one end of the plug rod 403. A spring 406 is installed on one side of the limit block 404. One end of the spring 406 is connected to one side of the inner wall of the fixing cylinder 402.

[0028] In this embodiment, as Figure 3 As shown, there are four screw holes 304 in total, and the four screw holes 304 are distributed in a ring with the vertical center line of the mounting ring 301 as the origin.

[0029] In this embodiment, as Figure 2 and Figure 3As shown, there are two round rods 203 and two circular grooves 302, and the round rods 203 and the circular grooves 302 are symmetrically distributed about the vertical center line of the mounting ring 301. The external dimensions of the round rods 203 are consistent with the internal dimensions of the circular grooves 302.

[0030] In this embodiment, as Figure 2 and Figure 3 As shown, the top of the mounting ring 301 has an annular groove with an internal dimension structure that matches the external dimension structure of the insertion ring 202, and the bottom of the insertion ring 202 has a sealing ring.

[0031] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, there are two insertion blocks 204 and two rectangular slots 303, and the insertion blocks 204 and rectangular slots 303 are symmetrically distributed about the vertical center line of the mounting ring 301. The insertion blocks 204 have slots with internal dimensions that match the external dimensions of the insertion rod 403, and the rectangular slots 303 have holes with internal dimensions that match the external dimensions of the insertion rod 403.

[0032] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, a socket is provided on one side of the fixed cylinder 402, and the insertion rod 403 is slidably installed in the socket on the fixed cylinder 402. The limiting block 404 forms an elastic mechanism with the fixed cylinder 402 through the spring 406. The fixed components 4 are symmetrically distributed about the vertical center line of the mounting ring 301.

[0033] In this embodiment, as Figure 2 and Figure 4 As shown, both the bottom side of the insertion block 204 and the top side of the insertion rod 403 are provided with inclined surfaces.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the lightweight hydraulic actuator assembly operates as follows during use:

[0035] First, insert the round rod 203 of connecting component 2 into the circular groove 302, and simultaneously insert the insert block 204 into the rectangular groove 303. Insert the ring 202 into the annular groove on the mounting ring 301. The sealing ring at the bottom of the ring 202 contacts the bottom of the inner wall of the annular groove on the mounting ring 301. When the insert block 204 is inserted into the rectangular groove 303, the inclined surface on the insert block 204 contacts the inclined surface on the insert rod 403, pressing the insert rod 403 to one side. The spring 406 is compressed. When the insert rod 403 coincides with the slot on the insert block 204, the limiting block 404 is subjected to the elastic force of the spring 406, causing the insert rod 403 to move. The insert rod 403 then moves into the rectangular groove 303. The connecting component 2 is slidable and inserted into the slot on the insert block 204, thereby connecting and fixing the connecting component 2 to the mounting component 3. Then, screws are used to install the hydraulic actuator to the valve and other equipment through the screw hole 304 on the mounting ring 301. When maintenance of the hydraulic actuator is required, the pull rod 405 of the two fixing components 4 is pulled outward, the insert rod 403 and the limit block 404 move, and the spring 406 is compressed. When the insert rod 403 moves out of the slot on the insert block 204, the lightweight hydraulic actuator body 1 is moved upward, separating the connecting component 2 from the mounting component 3. The lightweight hydraulic actuator body 1 can be quickly disassembled, improving the convenience of maintenance of the hydraulic actuator.
