[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a fully mechanized oil cylinder debugging and pressure testing platform, comprising a workbench 1, two support plates 2 are fixedly connected to the left side of the top of the workbench 1, two mounting plates 3 are fixedly connected between the bottoms of the two support plates 2, oil cylinders 4 are installed on the tops of the two mounting plates 3, two joints 27 are fixedly connected to the tops of the oil cylinders 4, a hydraulic box 28 is fixedly connected to the right side of the top of the workbench 1, two hydraulic pumps 13 are arranged on the top of the hydraulic box 28, two pressure devices 26 are installed on the top of the hydraulic box 28, the pressure devices 26 are located on one side of the hydraulic pump 13, a delivery pipe 14 is installed on one side of the hydraulic pump 13, the delivery pipe 14 runs through the interior of the pressure device 26, and a conduit 15 is fixedly connected to the bottom of the delivery pipe 14, The bottom of the conduit 15 is installed on the top of the joint 27, and two fixing plates 5 are fixedly connected between the tops of the two support plates 2. The bottoms of the two fixing plates 5 are fixedly connected with a cylinder 6, and the output end of the cylinder 6 is fixedly connected with a connecting seat 7. A pressing block 8 is arranged below the connecting seat 7, and a fixing rod 9 is fixedly connected inside the pressing block 8. Springs 10 are sleeved at both ends of the fixing rod 9, and sliders 11 are fixedly connected on the opposite sides of the two springs 10. A connecting rod 12 is arranged between the slider 11 and the connecting seat 7. A collecting box 16 is fixedly connected to the bottom of the workbench 1, and a filter screen 17 is slidably connected inside the collecting box 16. Fixed components are installed on the left and right sides of the outside of the collecting box 16, and the fixed components are used to quickly remove the filter screen 17.

[0032] Specifically, the workbench 1 serves as the base of the entire debugging system, and two vertical support plates 2 are fixedly connected on the left side of its top by bolts. The two support plates not only provide structural support, but also play the role of dividing the area. Between the bottoms of the two support plates 2, two horizontal mounting plates 3 are fixedly connected, and the two mounting plates 3 constitute the mounting base of the oil cylinder 4. Corresponding grooves are provided on the mounting plates 3 to prevent the position of the oil cylinder 4 from deviating. The oil cylinder 4 is precisely mounted on the two mounting plates 3, and two joints 27 are fixed on the top of the workbench 1 for connecting the input channel of the hydraulic oil. A hydraulic box 28 is fixedly connected on the right side of the top of the workbench 1, which is a container for storing hydraulic oil. Two hydraulic pumps 13 are installed on the top of the hydraulic box 28, which are responsible for extracting the hydraulic oil from the box and sending it to the pressure device 26 through the delivery pipe 14. The pressure device 26 is located on one side of the hydraulic pump 13 and is used to monitor the actual pressure of the hydraulic oil. The delivery pipe 14 runs through the interior of the pressure device 26, ensuring real-time pressure monitoring of the hydraulic oil during the delivery process. The bottom of the delivery pipe 14 is connected to the joint 27 at the top of the oil cylinder 4 through the conduit 15, forming a complete hydraulic circuit. The cylinder 6 is started, and the piston rod of the cylinder 6 extends, driving the connecting seat 7 connected thereto to move downward synchronously. The movement of the connecting seat 7 is converted into a rotational movement through the connecting rod 12, thereby driving the slider 11 to slide on the fixed rod 9. In this process, the slider 11 is subjected to the resistance of the spring 10. This design ensures that the pressure of the lower pressing block 8 on the oil cylinder 4 is moderate, so that it can press the oil cylinder 4 to limit the position. A collection box 16 is fixedly connected to the bottom of the workbench 1 to collect the oil that may leak during the debugging process of the oil cylinder 4. A filter screen 17 is slidably connected inside the collection box 16. This filter screen 17 can effectively filter out impurities in the oil to ensure that the recovered oil is clean. Fixed components are installed on the left and right sides of the outside of the collection box 16. These fixed components are designed to quickly disassemble the filter screen 17 for easy regular cleaning and replacement.

[0033] Reference Figure 3 and Figure 4 The fixed component includes a frame 18, the outer side of the frame 18 is fixedly connected to the outer wall of the collection box 16, the inside of the frame 18 is slidably connected with a pull rod 19, one side of the outside of the pull rod 19 is sleeved with a spring 21, the other side of the outside of the pull rod 19 is fixedly connected with a baffle 20, the top of the frame 18 is fixedly connected with a frame 22, and a blocking block 23 is arranged inside the frame 22.

[0034] Specifically, the frame 18 is fixedly connected to the outer wall of the collection box 16. As a frame structure, it provides a sliding track for the pull rod 19 and the baffle 20, and is also the external support structure of the fixed component. The pull rod 19 is slidably connected inside the frame 18. It is an operating component in the fixed component. The user can quickly disassemble or install the filter 17 by pulling the pull rod 19. The baffle 20 is fixedly connected to the outer side of the pull rod 19. Its function is to prevent the pull rod 19 from separating from the frame 18 when the pull rod 19 moves. The spring 21 is mounted on the other side of the pull rod 19. It provides an elastic force so that the pull rod 19 can automatically return to its original position when there is no external force, thereby keeping the filter 17 fixed.

[0035] Reference Figure 2 - Figure 4 A handle 24 is fixedly connected to the front side of the collecting box 16, supporting legs 25 are fixedly connected to both sides of the bottom of the working table 1, the inside of the slider 11 is slidably connected to the outside of the fixing rod 9, the other end of the spring 10 is fixedly connected to the inner wall of the lower pressing block 8, one end of the connecting rod 12 is rotatably connected to the bottom of the connecting seat 7, and the other end of the connecting rod 12 is rotatably connected to the top of the slider 11, one end of the spring 21 is fixedly connected to the inner wall of the frame 18, and the other end of the spring 21 is fixedly connected to the middle part of the baffle 20, the outer side of the blocking block 23 is slidably connected to the inside of the frame 22, and the bottom of the blocking block 23 is slidably connected to the inside of the frame 18, one end of the pull rod 19 passes through the collecting box 16 and is inserted into the filter 17, and the outer side of the baffle 20 is slidably connected to the inside of the frame 18.

[0036] Specifically, the collecting box 16 is a container for collecting oil that may leak during the commissioning of the oil cylinder. A handle 24 is fixedly connected to the front side thereof, which is convenient for the operator to take out the filter 17. The design of the handle 24 takes ergonomics into consideration, ensuring that the operator can maintain comfort and stability when taking out the filter 17. The slider 11 is internally slidably connected to the outside of the fixed rod 9. This design allows the slider to move freely along the fixed rod while maintaining linear motion. The other end of the spring 10 is fixedly connected to the inner wall of the lower pressing block 8. When the slider 11 is moved by an external force, the spring 10 will generate a reaction force, so that the lower pressing block 8 can stably press the oil cylinder 4. One end of the connecting rod 12 is rotatably connected to the bottom of the connecting seat 7, and the other end is rotatably connected to the top of the slider 11. In this way, the connecting rod can transmit force and motion between two points, realize complex motion conversion, and ensure that the lower pressing block 8 can accurately align with the oil cylinder 4 and apply pressure. One end of the spring 21 is fixedly connected to the inner wall of the frame 18, and the other end is fixedly connected to the middle of the baffle 20. When the pull rod 19 is pulled, the spring 21 is compressed and stores energy. When the pull rod 19 is released, the restoring force of the spring 21 will return the pull rod 19 and the baffle 20 to their original positions. The outer side of the blocking block 23 is slidably connected to the inside of the frame 22, and the bottom is slidably connected to the inside of the frame 18. Its function is to prevent the baffle 20 from moving when the filter 17 is removed, ensuring that the pull rod 19 can smoothly detach from the filter 17. When the filter 17 needs to be reinstalled, the blocking block 23 is removed, allowing the baffle 20 and the pull rod 19 to reset. One end of the pull rod 19 passes through the collection box 16 and is plugged into the inside of the filter 17, so that the pull rod can directly act on the filter, achieving rapid disassembly and installation. The outer side of the baffle 20 is slidably connected to the inside of the frame 18. Its function is to move with the pull rod 19 and provide support when the pull rod 19 is reset, ensuring that the pull rod 19 can be firmly inserted into the inside of the filter 17.

[0037] Working principle: Place the oil cylinder 4 on top of the two mounting plates 3, start the cylinder 6 to drive the connecting seat 7 to move downward synchronously, and at the same time drive the connecting rod 12 to rotate, and then drive the slider 11 to slide on the outside of the fixed rod 9, thereby compressing the spring 10, so that the lower pressure block 8 tightly presses the oil cylinder 4, and then connect the interface 16 with the joint 23, insert the interface into the joint 23, and use the hydraulic pump 13 to extract the hydraulic oil in the hydraulic box 28, and then enter the oil cylinder 4 through the delivery pipe 14 and the conduit 15. The hydraulic pressure entering the oil cylinder 4 can be detected by the pressure device 26 to prevent the internal hydraulic pressure of the oil cylinder 4 from being too high and causing certain dangers. When the hydraulic pressure is too high, the alarm will sound.

[0038] When the hydraulic cylinder leaks oil during the detection process, the oil will drip into the collection box 16, and the impurities contained in the dripping oil will be filtered out under the action of the filter 17, thereby realizing the recycling of the oil. When the filter 17 is used for a long time, impurities will accumulate more and more. Irregular cleaning will cause the filter 17 to be blocked, thereby affecting the filtering effect of the filter 17. At this time, the pull rod 19 is pulled outward to drive the baffle 20 to move synchronously, thereby compressing the spring 20, so that the blocking block 23 slides into the frame 18, thereby preventing the baffle 20 from moving until the pull rod 19 is completely separated from the filter 17. At this time, the handle can be pulled to take the filter 17 out of the collection box 16 for cleaning. When installation is required, the filter 17 is reinserted into the collection box 16, and the blocking block 23 is removed from the frame 18. At this time, the pull rod 19 is pushed inward to drive the baffle 20 to move synchronously, so that the spring 21 is reset, until the pull rod 22 is tightly inserted into the filter 17 to complete the installation.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
