Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a hydraulic synchronization control device. Background Technology

[0002] When processing and manufacturing general equipment such as pumps, hydraulic synchronization control devices are generally used to control the direction and flow rate of the liquid inside the hydraulic cylinder, so as to realize the synchronous movement of the hydraulic cylinder body, thereby enabling the hydraulic cylinder to stably clamp the workpiece to be processed.

[0003] Existing hydraulic synchronization control devices generally consist of a hydraulic pump, controller, sensor, hydraulic cylinder, connecting pipe, hydraulic control valve, etc. During use, the hydraulic pump delivers hydraulic oil to the hydraulic cylinder through the connecting pipe, enabling the hydraulic cylinder to push the clamping block to move. The sensor can then monitor the operating status of the hydraulic cylinder in real time, such as position, speed, and pressure, and feed the information back to the controller. The controller receives the signals from the sensor and issues control commands to adjust the flow direction and flow rate of the hydraulic oil, ensuring the synchronous operation of multiple actuators.

[0004] However, after prolonged use, the connection between the connecting pipe and the hydraulic cylinder will wear or corrode, affecting its stability and requiring replacement of the connecting pipe. This necessitates the use of specific tools to remove the bolts on the connecting pipe. Due to the narrow space in the connection area, the use of these tools is inconvenient, resulting in low efficiency in replacing the connecting pipe and consequently affecting the normal service life of the hydraulic cylinder.

[0023] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Example 1: Please refer to Figures 1 to 7 This utility model provides a technical solution: a hydraulic synchronization control device, including a hydraulic cylinder 1. Two mounting rings 2 are fixedly connected to the top of the hydraulic cylinder 1. A connecting pipe 17 is inserted into the inside of each mounting ring 2, allowing the connecting pipe 17 to be conveniently installed on the hydraulic cylinder 1. Two limiting rings 3 are slidably connected inside the mounting rings 2, limiting the limiting rings 3 and preventing them from shifting during sliding. A rubber ring 4 is inserted into the inner side of each limiting ring 3, fitting snugly against the outside of the connecting pipe 17. The rubber ring 4 has a high surface friction, allowing for stable installation of the rubber ring 4. 4 can limit the connection pipe 17, thereby making the connection pipe 17 more stable to be installed. The hydraulic cylinder 1 is the execution unit of the hydraulic synchronization control device. It is used in conjunction with the hydraulic pump, controller, sensor, hydraulic control valve and other structures. When in use, the hydraulic pump delivers hydraulic oil to the hydraulic cylinder 1 through the connection pipe 17, so that the hydraulic cylinder 1 can push the clamp to move. Then the sensor can monitor the position, speed, pressure and other operating status of the hydraulic cylinder 1 in real time and feed the information back to the controller. The controller receives the signal from the sensor and issues control commands to adjust the flow direction and flow rate of the hydraulic oil to ensure the synchronous operation of multiple actuators.

[0025] When it is necessary to disassemble the connecting pipe 17, the two limiting rings 3 are pulled to opposite sides, which causes the limiting rings 3 to move the rubber ring 4 outward, thereby separating the rubber ring 4 from the connecting pipe 17. Then, the connecting pipe 17 is pulled upward, allowing it to easily detach from the hydraulic cylinder 1. Subsequently, a new connecting pipe 17 is inserted into the mounting ring 2, and the two limiting rings 3 are moved to the side closer together, causing the limiting rings 3 to bring the rubber ring 4 into contact with the connecting pipe 17. This allows the rubber ring 4 to limit the connection pipe 17, making the installation of the connecting pipe 17 more stable.

[0026] Example 2: Based on Example 1, to facilitate the pulling of the rubber ring 4, two limiting grooves 5 are provided inside the mounting ring 2. A limiting ring 3 is slidably connected inside the limiting grooves 5, and the limiting grooves 5 limit the limiting ring 3, allowing it to slide smoothly. The rubber ring 4 is slidably connected inside the limiting grooves 5, and the limiting grooves 5 limit the rubber ring 4, preventing it from shifting during movement. A pull rope 6 is slidably connected inside the limiting grooves 5, and the limiting grooves 5 limit the pull rope 6, allowing it to slide smoothly. An elastic element 9 is sleeved on the outside of the pull rope 6. One end of the pull rope 6 is fixedly connected to a pull ring 10, which is slidably connected to the outside of the mounting ring 2. The mounting ring 2 limits the pull ring 10 so that it will not deviate when sliding. The other end of the pull rope 6 is fixedly connected to a compression plate 7, which is slidably connected to the inside of the limiting groove 5. The limiting groove 5 limits the compression plate 7 so that it can slide smoothly. The end of the compression plate 7 away from the pull rope 6 is fixedly connected to a connecting rod 8, and the other end of the connecting rod 8 is fixedly connected to the limiting ring 3. One side of the elastic element 9 is fixedly connected to the inner wall of the limiting groove 5, and the other end of the elastic element 9 is fixedly connected to the compression plate 7.

[0027] When the limiting ring 3 needs to be moved, the mounting ring 2 is pulled down, which causes the mounting ring 2 to move the pull rope 6 outward, which in turn causes the pull rope 6 to move the compression piece 7 outward. This causes the pull rope 6 to cause the compression piece 7 to compress the elastic element 9, causing the compression piece 7 to deform and pull the connecting rod 8 outward. This causes the connecting rod 8 to move the limiting ring 3 outward. Conversely, by releasing the pull ring 10, the elastic element 9 can perform a reset movement, which in turn causes the elastic element 9 to push the compression piece 7 inward. This causes the compression piece 7 to push the limiting ring 3 inward via the connecting rod 8.

[0028] Example 3: Based on Example 2, in order to facilitate the replacement of the rubber ring 4, two slots 11 are provided on the inner side of the limiting ring 3. A sealing groove 12 is provided on the inner wall of the slot 11. A placement groove 15 is provided on the inner side of the limiting ring 3. A placement ring 16 is slidably connected inside the placement groove 15. The placement groove 15 limits the placement ring 16. With the cooperation of the placement groove 15 and the placement ring 16, the rubber ring 4 can be installed smoothly. The placement ring 16 is fixedly connected to the outer side of the rubber ring 4. Two inserts 13 are fixedly connected to the outer side of the rubber ring 4. The inserts 13 are inserted into the inside of the slots 11. A sealing block 14 is fixedly connected to the outside of the inserts 13. The sealing block 14 is slidably connected inside the slots 11. The slots 11 can squeeze the sealing block 14 to produce deformation. The sealing block 14 fits against the inside of the sealing groove 12, which increases the friction between the inserts 13 and the slots 11, thereby making the installation of the rubber ring 4 more stable.

[0029] When the rubber ring 4 needs to be replaced, by pulling the rubber ring 4 inward, the rubber ring 4 can cause the insert 13 to disengage from the inside of the slot 11, which in turn causes the insert 13 to disengage from the inside of the slot 11, thus making the rubber ring 4 easy to disassemble. Conversely, by inserting the insert 13 into the inside of the slot 11 and causing the sealing block 14 to slide into the inside of the slot 11, the slot 11 can compress the sealing block 14 and deform it. When the rubber ring 4 and the limiting ring 3 are in contact, the insert 13 can engage with the inside of the slot 11, allowing the sealing block 14 to enter the inside of the sealing groove 12 and perform a reset movement, thus allowing the sealing block 14 to fit against the inner wall of the sealing groove 12, thus making the rubber ring 4 easy to install.

[0030] In actual use, by pulling the mounting ring 2 downwards, the mounting ring 2 causes the pull rope 6 to move outwards, which in turn causes the pull rope 6 to move the compression plate 7 outwards. This causes the compression plate 7 to compress the elastic element 9, deforming it and pulling the connecting rod 8 outwards. This, in turn, causes the connecting rod 8 to move the limiting ring 3 outwards, separating the rubber ring 4 from the connecting tube 17. Pulling the connecting tube 17 upwards then allows for easy disassembly. Pulling the rubber ring 4 inwards then causes the insert block 13 to disengage from the slot 11, which in turn causes the sealing block 14 to disengage from the slot 11, allowing for easy disassembly of the rubber ring 4. Finally, by inserting the insert block 13 into the slot 11 and allowing the sealing block 14 to slide into the slot 11, the rubber ring 4 can be easily disassembled. This causes the groove 11 to compress the sealing block 14, causing deformation. When the rubber ring 4 and the limiting ring 3 are in contact, the insert block 13 engages with the inside of the groove 11, allowing the sealing block 14 to enter the interior of the sealing groove 12 and perform a reset movement. This allows the sealing block 14 to fit against the inner wall of the sealing groove 12, facilitating the installation of the rubber ring 4. By releasing the pull ring 10, the elastic element 9 performs a reset movement, pushing the extrusion plate 7 inward. This allows the extrusion plate 7 to push the limiting ring 3 inward via the connecting rod 8, causing the limiting ring 3 to bring the rubber ring 4 into contact with the outside of the connecting pipe 17. No bolts are required for installation, making the replacement of the connecting pipe 17 more convenient and efficient, without affecting the normal use of the hydraulic cylinder 1.
