Description

Technical Field

[0001] The present invention relates to the technical field of servo central control cylinder detection and maintenance, and in particular to a servo central control cylinder maintenance device with a leakage feedback function. Background Art

[0002] The servo cylinder is a modular product that integrates a servo motor and a lead screw. It converts the servo motor's rotary motion into linear motion. At the same time, it transforms the servo motor's best advantages - precise speed control, precise rotational speed control, and precise torque control - into precise speed control, precise position control, and precise thrust control, thus creating a new revolutionary product in the high-precision linear motion series.

[0003] Generally, there are two types of leakage in servo cylinders: external leakage and internal leakage. External leakage refers to the leakage of oil from various lax seals into the atmosphere outside the cylinder body. Common external leakage includes the following three places: first, oil leakage at the sealing part between the cylinder liner and the cylinder head. The cylinder liner and the cylinder head of the cylinder body of engineering machinery are mostly connected by threads, and then an O-ring is added at the threaded port. When oil leakage occurs here, it is mostly due to damage of the O-ring. The problem can be solved by replacing a suitable new O-ring; second, oil leakage at the relative movement between the piston rod and the guide sleeve. Usually, the piston rod is sealed with an O-ring or a Y-ring here. Since there is dry friction between the piston rod and the seal, the friction resistance is large, which often aggravates the wear of the seal; in addition, the extended surface of the piston rod contacts with various impurities, which often causes scratches, grooves, pitting or rust on the surface of the piston rod, aggravating the wear of the seal and even cutting the seal; third, oil leakage caused by lax sealing at the cylinder joint. Impact and vibration will cause the pipe joint to loosen and cause oil leakage;

[0004] Internal leakage refers to leakage from the high-pressure chamber to the low-pressure chamber through various gaps inside the cylinder. Usually, this type of leakage is difficult to detect and can only be judged by system working conditions such as insufficient thrust, speed drop, unstable operation or increased oil temperature. Common internal leakage is divided into oil leakage at the static seal between the piston rod and the piston and leakage at the dynamic seal between the inner wall of the cylinder liner and the piston. The existing cylinder detection device does not accurately analyze and judge the internal and external leakage of the entire cylinder, which will cause the cylinder to continue to leak oil. At the same time, the corresponding repair and maintenance should be carried out during the detection of the cylinder to avoid further leakage problems in the cylinder in the future.

[0005] For this reason, a servo central control cylinder maintenance device with a leakage feedback function is urgently needed. Summary of the Invention

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-7 , the present invention provides a technical solution:

[0031] Example 1:

[0032] Without disassembling the cylinder 701, it is difficult to detect the internal leakage of the cylinder 701. Only by relying on the working conditions of the system, such as insufficient thrust, speed drop, unstable operation or oil temperature increase, can we judge whether there is oil leakage inside the cylinder 701. Figure 1-4 As shown, a servo valve 709 is installed on the cylinder body 701 of the entire hollow cylinder mechanism 7, and a guide tube 708 is connected to one side of the servo valve 709. In the early stage of production of the entire servo hydraulic cylinder, hydraulic oil is not poured into the entire cylinder body 701. When the cylinder body 701 has been working for a period of time, the hydraulic oil in the cylinder body 701 needs to be discharged in time during inspection. A sleeve block 702 is installed on one side of the entire cylinder body 701, and an oil seal sleeve 703 is fixed to one side of the sleeve block 702 by bolts. The side cross-sectional structure of the entire sleeve block 702 is shown as follows: Figure 3As shown, the top and side of the sleeve block 702 are respectively provided with a first oil inlet hole 705 and a second oil inlet hole 707. At the same time, the first oil inlet hole 705 and the second oil inlet hole 707 are both connected to the cylinder body 701 to prevent oil leakage at the first oil inlet hole 705 and the second oil inlet hole 707 when the cylinder body 701 is working normally. The two oil inlet holes are connected with plugs. When performing inspections, the staff needs to remove the plugs at the first oil inlet hole 705 and the second oil inlet hole 707 in advance.

[0033] When the entire cylinder body 701 is tested, the entire hollow cylinder mechanism 7 needs to be fixed to the slider 2, such as Figure 1 、 Figure 4 As shown, the slide rail 3 on the entire slider 2 is symmetrically connected with an F-type clamping block 6, and the entire F-type clamping block 6 slides freely in the slide rail 3. When the position of the entire F-type clamping block 6 is determined, the fixing bolts for fixing the F-type clamping block 6 can be inserted into the fixing grooves 5 on both sides of the slider 2. At the same time, in order to facilitate the internal leakage detection of the entire cylinder body 701, the baffle 4 on the outside of the oil seal sleeve 703 of the piston rod 704 must be unfolded, and one end of the piston rod 704 must be limited. When the preparation work is completed, the guide mechanism on one side of the entire slider 2 drives the entire slider 2 to move on the top of the workbench 1 and makes the entire slider 2 move to the bottom of the console 8. At this time, the staff will seal the first oil inlet hole 705 and the second oil inlet hole 707 on the sleeve block 702, and start the leakage detection of the cylinder body 701. First, the sealing caps 706 on the first oil inlet hole 705 and the second oil inlet hole 707 are removed, and the staff rotates the first connecting pipe 12 and the sealing sleeve 13 on the second oil guide pipe 15, so that the first connecting pipe 12 is connected to the first oil inlet hole 705, and the second oil guide pipe 15 is connected to the second oil inlet hole 707. At this time, one end of the external pressurizing device is connected to one end of the connecting pipe 18, and air is started to be injected into the entire liquid storage tank 10 filled with hydraulic oil. At this time, the hydraulic oil in the liquid storage tank 10 flows along the first connecting pipe 12 and the first oil inlet hole 705 into one end of the cylinder body 701. When one side of the piston rod 704 of the entire cylinder body 701 is filled with hydraulic oil, the second oil guide pipe 15 connected to one side of the sleeve block 702 is also filled with hydraulic oil. Because one end of the entire second oil guide pipe 15 is connected to the temperature control detection module 9, the temperature of the hydraulic oil in the second oil guide pipe 15 is detected in real time. At the same time, one end of the entire second oil guide pipe 15 is connected to the first oil guide pipe 14, and one end of the entire first oil guide pipe 14 is installed with a hydraulic sensor 11 to record the hydraulic oil pressure changes in the entire first oil guide pipe 14 in real time.

[0034] During the specific detection, an external pressurizing device is required to increase the pressure every 30 seconds so that one side of the piston rod 704 in the entire cylinder 701 maintains 2 bar for 3 minutes. This operation is performed 3 times, wherein each pressurization and pressure-maintaining operation is mixed with a pressure relief operation in the middle, so that the hydraulic oil in the entire first oil guide pipe 14 and the second oil guide pipe 15 enters the cylinder 701. The diameter of the entire first oil guide pipe 14 and the second oil guide pipe 15 is half of the first connecting pipe 12, which plays a role in signal amplification, so that the entire hydraulic sensor 11 can better detect the hydraulic pressure changes in the cylinder 701, while preventing the entire pressure relief operation from being carried out. A pressure relief cylinder 19 is connected to one end of the second connecting pipe 16. The entire stamping value can be understood by the pressure gauge 17 installed on one side of the first connecting pipe 12. When a leak occurs in the entire cylinder 701, part of the hydraulic oil at one end of the piston rod 704 flows between the piston and the piston rod 704 or between the inner wall of the cylinder 701 and the piston into the cylinder 701 on the other side of the low-pressure piston, causing the oil pressure in the entire second oil guide pipe 15 and the first oil guide pipe 14 to decrease. At the same time, the hydraulic oil in the entire cylinder 701 flows along the inner wall of the cylinder 701, and the temperature rises. The entire temperature control detection module 9 monitors the temperature of the entire cylinder 701, the second oil guide pipe 15 and the first oil guide pipe 14 in real time, further improving the detection accuracy of the leak in the entire cylinder 701.

[0035] After the leakage detection of the entire cylinder body 701 is completed, the electronically controlled valve located on the first oil guide pipe 14 is opened. At this time, the external pressurizing device presses the hydraulic oil in the cylinder body 701 back into the liquid storage tank 10, so that the entire hydraulic oil can be recycled. When the leakage detection of the cylinder body 701 is performed, the servo valve 709 and the guide pipe 708 located on one side of the entire cylinder body 701 are in a closed state. Usually, the external leakage detection of the cylinder body 701 is performed first, and then the internal leakage detection of the cylinder body 701 is performed to avoid multiple variables appearing during the internal leakage detection of the cylinder body 701, which may affect the detection of the entire cylinder body 701.

[0036] Example 2:

[0037] Remove the first connecting pipe 12 and the second oil guide pipe 15 connected to the first oil inlet hole 705 and the second oil inlet hole 707, and at the same time, the entire slider 2 enters the bottom of the repair cover 20, as shown in FIG. Figure 6As shown, a first guide rail mechanism 28 is installed at the bottom of the entire repair cover 20. The entire first guide rail mechanism 28 belongs to a transmission mechanism, which is used to drive the entire second telescopic rod 32 to move left and right at the bottom of the signal transmission box 27. When working, the piston rod 704 in the entire cylinder body 701 is first pulled out. At this time, the motor 21 located at the top of the repair cover 20 starts to work, and the motor 21 drives the first rotating shaft 22 on the entire fixed frame 23 to rotate. The second rotating shaft 24 is movably connected to the inner wall of the fixed frame 23 through a bearing. The first rotating shaft 22 and the second rotating shaft 24 are engaged with each other through gears, so that the rotation of the entire first rotating shaft 22 drives the two second rotating shafts 24 to rotate, and the second rotating shaft 24 is engaged with the first rotating shaft 22 and the second rotating shaft 24. A movable rod 25 is fixedly mounted on the second rotating shaft 24. When the movable rod 25 moves to the right, it will drive the piston rod 704 in the entire cylinder body 701 to extend. At the same time, the first telescopic rod 30 located at the bottom of the first guide rail mechanism 28 starts to work. Driven by the first guide rail mechanism 28, the first telescopic rod 30 adjusts the position between the analysis ring 29 and the piston rod 704 so that the analysis ring 29 and the piston rod 704 are on the same horizontal plane. At this time, driven by the first guide rail mechanism 28, the analysis ring 29 begins to perform flaw detection on the outer wall of the entire piston rod 704. Through the detection of the analysis ring 29, the corresponding signal is transmitted to the signal transmission box 27, and finally displayed on the entire console 8;

[0038] When the outer wall of the entire piston rod 704 is damaged, the console 8 controls the motor 21 to rotate, so that the entire movable rod 25 controls the first telescopic rod 30 on one side of the entire storage box 26 to move to the damaged part of the piston rod 704. At the same time, the entire first telescopic rod 30 starts to work, pushing the first glue spraying arc 31 and the second glue spraying arc 33 to the damaged part of the piston rod 704, and evenly spraying the metal glue to the surface of the piston rod 704, waiting for the metal glue on the surface of the entire piston rod 704 to be completely solidified. At this time, the slider 2 drives the entire cylinder body 701 into the polishing box 36 area to perform the cleaning and calibration operation of the piston rod 704 surface. Figure 7 As shown, the inner walls of both sides of the entire polishing box 36 are installed with a second guide rail mechanism 37 and an ash storage box 40. First, the bolts on the entire oil seal sleeve 703 are removed, and then the entire oil seal sleeve 703 is clamped by the clamping rod 38 on the second guide rail mechanism 37, so that the entire oil seal sleeve 703 moves left and right on the piston rod 704, so that the entire oil seal sleeve 703 scrapes off the excess metal glue. At the same time, the fan on one side of the entire second guide rail mechanism 37 is started, and the wind produced by the entire fan reaches the piston rod 704 along the air outlet 39. On the one hand, it accelerates the solidification of the metal glue on the surface of the entire piston rod 704, and on the other hand, the wind blows the metal glue that falls to the bottom of the polishing box 36 into the ash storage box 40 for storage.

[0039] Since part of the cylinder body 701 carries a lot of impurities on the piston rod 704 before the inspection, it is necessary to clean the entire piston rod 704. A cleaning box 34 is symmetrically installed on the top of the workbench 1. A clamping device is also installed on the top of the entire cleaning box 34. The staff fixes one end of the piston rod 704 on the entire cylinder body 701 to the clamping device, and the top of the entire clamping device is connected to the rotating frame 35 on one side of the movable plate. When the entire motor 21 drives the movable plate to move, the movable plate drives the entire rotating frame 35 to move the clamping mechanism in the cleaning box 34, so that the entire clamping device pulls the piston rod 704 on the cylinder body 701. At the same time, the cleaning device located in the cleaning box 34 sprays gasoline to the surface of the piston rod 704, and cleans the surface of the entire piston rod 704 to avoid impurities on the surface of the piston rod 704, which affects the inspection of the entire analysis ring 29;

[0040] In order to avoid additional variables when testing the internal leakage of the entire cylinder body 701, such as the entire cylinder body 701 having both internal leakage and external leakage, which affects the entire staff's subsequent judgment and maintenance, the cylinder body 701 is first tested for external leakage and then for internal leakage. In the early stage of the entire internal leakage test, the oil leakage at the sealing part of the cylinder liner and cylinder head, the oil leakage at the relative movement between the piston rod 704 and the guide sleeve, and the oil leakage caused by poor sealing at the joint of the cylinder body 701 are solved one by one. Such external oil leakage is usually caused by damage to the O-ring and Y-ring that serve as a seal. Therefore, when testing the internal leakage of the cylinder body 701, the block 702 and the oil seal sleeve 703 template assembly that match the newly installed O-ring and Y-ring can be fixed to the cylinder body 701 in advance to facilitate the internal leakage test of the entire cylinder body 701. The common external leakage problem of the cylinder body 701 mentioned above will cause hydraulic oil leakage at the corresponding position. The staff can avoid the external leakage problem of the cylinder body 701 by replacing 13 rings of the sealing sleeve in time.
