Description

Technical Field

[0001] This utility model relates to the field of hydraulic oil filling technology, specifically to a hydraulic oil filling limiting device. Background Technology

[0002] Currently, large hydraulic oil manufacturers generally use fully automated filling lines. While these lines can achieve high-precision positioning, quantitative filling, and continuous operation, their equipment purchase costs can reach hundreds of thousands of yuan. They also require a professional installation and commissioning team, as well as ongoing maintenance personnel. Furthermore, they place high demands on the spatial layout of the production site and power supply. For small factories or workshops with limited annual production capacity and financial resources, the initial investment and operating costs of fully automated production lines far exceed their capacity. Therefore, these companies mostly choose simpler, lower-cost manual or semi-manual filling devices.

[0003] However, existing simple filling devices lack effective limiting and positioning structures. During the filling process, operators need to manually align the opening of the filling container with the filling head. Manual operation is easily affected by visual deviation, hand stability and operator skill, resulting in frequent misalignment of the container opening and the filling head. This causes hydraulic oil to spill during filling, which not only wastes raw materials but also contaminates the workbench and the floor, increasing the manpower and time costs of cleaning.

[0004] Therefore, developing a hydraulic oil filling and limiting device that is simple in structure, low in cost, and capable of precise container positioning has become an urgent need to address current industry pain points. To this end, a hydraulic oil filling and limiting device is proposed. Summary of the Invention

[0008] Preferably, the lifting mechanism includes two support plates, both of which are installed on the middle of the front surface of the frame, and a threaded rod is installed between the two support plates, with the lifting plate and the threaded rod being threadedly connected.

[0009] Preferably, a limit rod is also installed between the two support plates, the lifting plate is slidably connected to the limit rod, and a turntable is installed on the support plate to facilitate the rotation of the threaded rod.

[0010] Preferably, the upper part of the connecting rod is provided with an external thread to facilitate the connection of the fixing nut.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Please see Figures 1-3This utility model provides a technical solution: a hydraulic oil filling and limiting device, including a frame 1. A lifting mechanism 2 is installed on the middle of the front surface of the frame 1, which can drive components to lift and lower to adapt to different filling height requirements. A lifting plate 5 for supporting the filling components is installed on the lifting mechanism 2. Two filling heads 6 for injecting hydraulic oil into the container are symmetrically installed at both ends of the lifting plate 5, realizing synchronous filling at two stations and improving filling efficiency. Multiple adjustment grooves 7 for adjusting the position of the connecting rod 8 are evenly opened at both ends of the lifting plate 5. Multiple fixing nuts 10 for fixing the position of the connecting rod 8 in the adjustment grooves 7 are installed above the connecting rod 8. The position of the connecting rod 8 can be flexibly adjusted by tightening and loosening the fixing nuts 10 to adapt to different filling containers. A rubber cylinder 9 for contact limiting with the filling container is rotatably connected below the connecting rod 8. The rubber material can avoid scratching the container mouth, and the rotation design can reduce the frictional resistance when the container is placed, ensuring accurate container positioning.

[0021] like Figure 2 As shown: The lifting mechanism 2 includes two support plates 21 for fixing and installing the transmission components. Both support plates 21 are installed in the middle of the front surface of the frame 1 to form a stable transmission support structure. A threaded rod 23 that can rotate to drive the lifting plate 5 to move is installed between the two support plates 21. The lifting plate 5 is threadedly connected to the threaded rod 23. By rotating the threaded rod 23 forward and backward, the lifting plate 5 can be driven to move up and down along the axial direction of the threaded rod 23, so as to realize the adjustment of the height of the filling head 6 and meet the filling needs of containers of different heights.

[0022] like Figure 2 As shown: A limiting rod 22 is also installed between the two support plates 21 to limit the rotation direction of the lifting plate 5. The lifting plate 5 is slidably connected to the limiting rod 22 to prevent the lifting plate 5 from rotating synchronously with the threaded rod 23, ensuring that the lifting plate 5 only rises and falls stably along the axial direction. A turntable 24 is installed on the support plate 21 to facilitate manual rotation of the threaded rod 23. The operator can easily drive the threaded rod 23 to rotate by rotating the turntable 24, which is convenient to operate and reduces the difficulty of adjustment.

[0023] like Figure 3 As shown: The upper part of the connecting rod 8 is provided with an external thread 81 for easy connection with the fixing nut 10. The external thread 81 is adapted to the internal thread of the fixing nut 10. By tightening the fixing nut 10, the connecting rod 8 can be tightly fixed in the adjusting groove 7 to prevent the connecting rod 8 from shifting and ensure the stability of the limiting effect. At the same time, after loosening the fixing nut 10, the position of the connecting rod 8 can be quickly adjusted, making the operation flexible.

[0024] like Figure 3As shown: The front surface of the frame 1 is provided with a through groove 3 for the pipe to pass through. The filling head 6 is connected to a pipe for conveying hydraulic oil. The pipe passes through the inside of the through groove 3. The through groove 3 provides reasonable arrangement space for the pipe, avoiding collision or entanglement between the pipe and the frame 1 during the lifting of the lifting plate 5, ensuring the stability of the hydraulic oil conveying pipe, and making the overall structure of the device neater and reducing space occupation.

[0025] like Figure 1 As shown: The frame 1 is equipped with a weighing device 4 for real-time detection of the total weight of the container and hydraulic oil during the filling process. The weighing device 4 can accurately measure the filling weight. When the weight reaches the preset value, it can promptly provide a feedback signal to facilitate control of the filling head 6 to stop filling, thereby achieving quantitative filling of hydraulic oil, improving filling accuracy, and avoiding problems of overfilling or underfilling.

[0026] like Figure 1 As shown: The frame 1 is equipped with a controller for receiving signals and controlling the movement of components. The controller is electrically connected to the weighing device 4 and the filling head 6. The weighing device 4 transmits the detected weight signal to the controller in real time. When the weight reaches the set threshold, the controller automatically sends a stop signal to the filling head 6 to control the filling head 6 to close, thereby realizing the automated control of the filling process, reducing manual intervention, improving filling efficiency and accuracy, and reducing human operation errors.

[0027] Working principle: Before starting the hydraulic oil filling operation, the height of the container to be filled needs to be adjusted. The operator rotates the turntable 24 installed on the support plate 21. The turntable 24 drives the threaded rod 23 between the two support plates 21 to rotate synchronously. Since the lifting plate 5 is threadedly connected to the threaded rod 23, and the lifting plate 5 is also slidably connected to the limit rod 22 between the support plates 21, the rotation of the threaded rod 23 is converted into the up and down movement of the lifting plate 5 along the axis of the limit rod 22 under the action of the limit rod 22 restricting the rotation of the lifting plate 5. This causes the filling head 6 installed at both ends of the lifting plate 5 to be adjusted to a height that matches the opening of the container, thus preventing hydraulic oil from spilling during filling.

[0028] After the height adjustment is complete, first loosen the fixing nut 10 above the connecting rod 8. At this time, the connecting rod 8 can move along the adjustment grooves 7 opened at both ends of the lifting plate 5. Place a standard container to be filled directly above the weighing device 4 on the frame 1, and align the container opening with the filling head 6. Then move the connecting rod 8 in the adjustment groove 7 until the rubber cylinder 9 rotatably connected below the connecting rod 8 is tightly fitted to the outer wall of the container. After confirming that the positioning is accurate, tighten the fixing nut 10 to fix the position of the connecting rod 8, forming a limiting frame that fits the container.

[0029] During the actual filling process, the container to be filled is placed within a limiting frame consisting of multiple sets of connecting rods 8 and rubber cylinders 9. The container will automatically align with the filling head 6 under the guidance of the limiting structure, eliminating the need for manual secondary calibration. After the filling system is started, hydraulic oil is delivered to the filling head 6 through a pipe connected to the filling head 6, and then injected into the container by the filling head 6.

[0030] During the filling process, the weighing device 4 will detect the total weight of the container and the internal hydraulic oil in real time and transmit the weight signal to the controller inside the frame 1. When the weight detected by the weighing device 4 reaches the filling threshold preset by the controller, the controller will immediately send a stop signal to the filling head 6 to control the filling head 6 to close, thereby achieving quantitative filling and avoiding overfilling or underfilling.

[0031] After the previous container is filled, it can be directly removed and placed into the next container to be filled. The new container will automatically enter the limiting frame along the guide of the rubber tube 9 and align with the filling head 6, eliminating the need for manual alignment and allowing the next round of filling to start quickly, significantly improving the efficiency of continuous filling.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
