Description

Technical Field

[0001] This invention relates to the field of hydraulic cylinder disassembly and assembly equipment, specifically to a hydraulic cylinder disassembly and assembly tooling and method. Background Technology

[0002] Hydraulic cylinders, as core actuators in hydraulic systems, are widely used in engineering machinery, metallurgical equipment, mining machinery, and other fields. During use, hydraulic cylinders are subjected to high pressure and high-frequency reciprocating motion for extended periods, which can lead to wear and aging of internal components such as seals and guide sleeves, requiring regular disassembly and maintenance.

[0003] Currently, the disassembly and assembly of hydraulic cylinders largely rely on manual labor. During disassembly, operators use simple tools such as wrenches and hammers to hold the cylinder barrel in place, then manually rotate the guide sleeve to disassemble it. Assembly requires the reverse operation, manually screwing the guide sleeve into the threaded hole at the cylinder barrel end. This traditional manual disassembly and assembly method has many drawbacks: First, it is labor-intensive, requiring operators to maintain a fixed posture for extended periods, easily leading to fatigue. Second, it has low efficiency, as the speed and torque of manual operation are limited, failing to meet the needs of batch repairs. Third, it suffers from poor precision, with uneven manual force application easily causing guide sleeve thread stripping, cylinder barrel deformation, and even damage to seals, affecting the quality of hydraulic cylinder repair. Fourth, it lacks safety, as the cylinder barrel is prone to shifting or falling off during disassembly and assembly, potentially causing injury to operators.

[0004] To address the aforementioned issues, some simple hydraulic cylinder assembly and disassembly aids have emerged in the existing technology, such as a structure combining a fixed bracket with a pneumatic wrench. However, these tools still have significant shortcomings: on the one hand, the clamping stability of the fixed bracket is poor, making it unsuitable for hydraulic cylinders of different specifications and lacking versatility; on the other hand, they lack a precise position adjustment mechanism, making it difficult to accurately align the output end of the pneumatic wrench with the guide sleeve, still requiring manual assistance for positioning, thus failing to achieve true automated operation and fundamentally solving the problem of reliance on manual labor.

[0005] Therefore, developing a disassembly and assembly tool that can achieve automatic clamping, precise positioning, efficient disassembly and assembly of hydraulic cylinders, and is highly versatile and safe, has become an urgent technical problem to be solved in the field of hydraulic cylinder repair equipment. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a hydraulic cylinder disassembly and assembly tooling device.

[0007] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a hydraulic cylinder disassembly and assembly tooling device, comprising a bearing component, a clamping unit, a position adjustment unit and a rotation unit; The clamping unit is mounted on the bearing assembly and is used to detachably fix the cylinder barrel of the hydraulic cylinder; The position adjustment unit includes a translation mechanism and a lifting mechanism. The translation mechanism slides with the clamping unit to achieve horizontal position adjustment. The lifting mechanism is connected between the translation mechanism and the rotary unit and is used to drive the rotary unit to move up and down in the vertical direction. The rotary unit includes a drive component and a rotary component. The drive component is connected to the rotary component for driving the rotary component to rotate in both directions. The rotary component is used to cooperate with disassembly and assembly tools to realize the disassembly and assembly of the hydraulic cylinder guide sleeve. Semi-automatic operation of hydraulic cylinder assembly and disassembly is achieved through the coordinated action of clamping unit, position adjustment unit and rotation unit.

[0008] Furthermore, the clamping unit includes a clamping module and a clamping cylinder. The clamping module is fixed to the bearing component by a mounting base. Fixed plates are provided at both ends of the clamping module. The clamping cylinder is connected to the fixed plates by bolts. The clamping module has a first V-shaped clamping block on its fixing plate and a second V-shaped clamping block at the end of the piston rod of the clamping cylinder. The first V-shaped clamping block and the second V-shaped clamping block are arranged opposite to each other and are used together to clamp the cylinder barrel.

[0009] Furthermore, the translation mechanism includes at least two cross sliders and a guide rail. The guide rail extends horizontally along the clamping module, the cross sliders slide in cooperation with the guide rail, and the lifting mechanism is fixedly connected to the cross sliders.

[0010] Furthermore, the lifting mechanism includes at least two lifting cylinders, the cylinder barrels of which are fixed to the cross slider by bolts, and the piston rods of which are fixedly connected to the bottom of the mounting platform of the rotary unit by bolts.

[0011] Furthermore, the rotary unit is fixed to the top end face of the mounting platform by bolts; The driving component is a servo motor, and the rotating component is a rotary table. The servo motor and the rotary table are connected by a transmission. The servo motor is electrically controlled to rotate forward and backward, thereby driving the rotary table to rotate forward and backward synchronously.

[0012] Furthermore, the load-bearing component is the fuel tank assembly; The mounting base and the fuel tank assembly are fixedly connected by welding, and the clamping module is integrally formed with the mounting base or can be detachably fixedly connected.

[0013] Furthermore, there are four cross-shaped sliders, which are symmetrically distributed on the guide rails of the clamping module. Furthermore, there are two lifting cylinders, which are symmetrically arranged on the cross slider.

[0014] This invention also provides a method for disassembling and assembling a hydraulic cylinder using a hydraulic cylinder disassembly and assembly tooling, comprising the following steps: S1: Place the cylinder to be disassembled or assembled in the clamping area of ​​the clamping unit, and drive the clamping components to move towards each other through the clamping unit to disassemble and fix the cylinder barrel. S2: The horizontal position of the rotary unit is adjusted by the translation mechanism of the position adjustment unit to achieve relative coordinate correction between the rotary unit and the cylinder guide sleeve. Then, the vertical height of the rotary unit is adjusted by the lifting mechanism of the position adjustment unit to make the rotary parts of the rotary unit compatible with the disassembly and assembly tools. S3: Connect one end of the disassembly and assembly tool to the cylinder guide sleeve, and the other end to the rotating part of the rotary unit. S4: By electrically controlling the drive of the rotary unit, the rotary unit is driven to rotate in both directions, and then the cylinder guide sleeve is driven to rotate synchronously by the disassembly and assembly tools, so as to disassemble or install the cylinder guide sleeve. S5: After disassembly and assembly are completed, control the clamping unit to release the cylinder barrel, remove the cylinder, and complete the disassembly and assembly operation.

[0015] The present invention has the following beneficial effects: The present invention provides a hydraulic cylinder disassembly and assembly tooling and method: (1) Through the coordinated design of clamping unit, position adjustment unit and rotary unit, no large amount of manpower is required and a single person can complete the disassembly and assembly of hydraulic cylinder guide sleeve, which greatly reduces labor costs and labor intensity. (2) The servo motor drives the rotary table to rotate precisely, replacing manual knocking, prying and other rough operations. The disassembly and assembly time of a single hydraulic cylinder guide sleeve is shortened to 20-30 minutes, and the efficiency is increased by 3-6 times. (3) The horizontal position can be precisely adjusted by the cross slider. Combined with the height adjustment of the lifting cylinder, the disassembly and assembly coordinates can be automatically corrected to ensure the coaxiality of the guide sleeve and the cylinder, and avoid the sealing failure caused by installation deviation. At the same time, the symmetrical clamping design of the V-shaped clamping block makes the cylinder evenly stressed, preventing cylinder deformation or scratches on the inner wall. (4) The adjustable clamping distance between the first V-shaped clamping block and the second V-shaped clamping block, combined with the adjustable design of horizontal position and vertical height, can be adapted to the disassembly and assembly of oil cylinders with different diameters and heights, and has strong versatility. (5) Each component is fixedly connected by bolts, welding and other methods, with high connection strength. The sliding fit between the cross slider and the guide rail, and the transmission fit between the servo motor and the rotary table have good stability, ensuring the reliability of operation during long-term use.

Detailed Implementation

[0017] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0018] like Figures 1 to 3 As shown, a hydraulic cylinder assembly and disassembly tooling includes a bearing assembly 1, a clamping unit, a position adjustment unit, and a rotation unit 4. Through the coordinated action of the clamping unit, the position adjustment unit, and the rotation unit 4, semi-automatic operation of hydraulic cylinder assembly and disassembly is achieved.

[0019] The bearing component 1 serves as the basic support and installation benchmark for the overall tooling, providing a stable assembly carrier for the clamping unit, position adjustment unit, and rotation unit 4, ensuring the relative position accuracy of each functional unit. Preferably, the bearing component 1 is an oil tank component, which can also serve as a collection container for waste oil in the oil cylinder, eliminating the need for an additional independent collection container, simplifying the overall layout of the tooling, and reducing the size and cost of the equipment.

[0020] The clamping unit is set on the bearing component 1. The clamping unit is used to detachably fix the cylinder barrel of the hydraulic cylinder to prevent the cylinder barrel from axial displacement, radial rotation or tilting during disassembly and assembly, and to provide a stable reference for subsequent disassembly and assembly of the guide sleeve. Specifically, the clamping unit includes a clamping module 2 and a clamping cylinder 6. The clamping module 2 is fixed to the bearing component 1 by a mounting base. The clamping module 2 has fixing plates 10 at both ends. The clamping cylinder 6 is bolted to the fixing plates 10. The mounting base and the oil tank component are fixedly connected by welding. The clamping module 2 and the mounting base are integrally formed or detachably fixedly connected.

[0021] The mounting base establishes a connection bridge between the clamping module 2 and the bearing component 1, thereby achieving a firm fixation of the clamping module 2, preventing the clamping module 2 from shifting during clamping or disassembly, and ensuring that the clamping reference does not deviate. The clamping module 2 has a first V-shaped clamping block 9 on its fixing plate 10 and a second V-shaped clamping block 13 at the piston rod end of the clamping cylinder 6. The first V-shaped clamping block 9 and the second V-shaped clamping block 13 are arranged opposite to each other and are used together to clamp the cylinder barrel. The fixing plate 10 simultaneously supports the first V-shaped clamping block 9 and the clamping cylinder 6, providing a precise relative installation position for both, ensuring that the first V-shaped clamping block 9 and the piston rod of the clamping cylinder 6 are coaxial. The clamping cylinder 6 provides automated and controllable clamping power, replacing the external force applied manually. The reciprocating motion of the second V-shaped clamping block 13 is achieved through the extension and retraction of the piston rod. The clamping force is stable and adjustable, adapting to cylinder barrels of different diameters, and realizing semi-automatic clamping. The first V-shaped clamping block 9 serves as a fixed clamping end, providing a stable support surface. The V-shaped structure can automatically adapt to the outer contour of the cylinder barrel, achieving initial centering and preventing cylinder barrel misalignment during placement. The second V-shaped clamping block 13 serves as a movable clamping end, moving synchronously with the piston rod of the clamping cylinder 6, forming a counter-clamping with the first V-shaped clamping block 9. The V-shaped structure fits tightly against the outer circle of the cylinder barrel, increasing the contact area and improving clamping stability. In addition, the self-centering characteristic of the V-shaped surface allows cylinder barrels of different diameters to automatically align their central axes after placement, adapting to the rotation center of the subsequent rotary unit 4, eliminating the need for additional cylinder barrel center calibration and simplifying operation. At the same time, the relative clamping method ensures symmetrical force on the cylinder barrel, avoiding cylinder barrel tilting or deformation caused by unilateral force. When the clamping cylinder 6 is not activated, its piston rod is in the retracted state. The second V-shaped clamping block 13 and the first V-shaped clamping block 9 form a sufficiently large clamping gap, which is larger than the diameter of the cylinder barrel of the cylinder 6 to be clamped, so as to facilitate the placement of the cylinder. At this time, the first V-shaped clamping block 9 is fixed on the fixing plate 10 and its position remains unchanged; the second V-shaped clamping block 13 is in the standby position with the piston rod to ensure that the cylinder can be placed smoothly. Then, the cylinder to be disassembled and installed is placed horizontally between the first V-shaped clamp 9 and the second V-shaped clamp 13. Utilizing the self-centering structure of the V-shaped clamps, when the outer circle of the cylinder contacts the inclined surface of the two V-shaped clamps, it will automatically slide to the center position of the V-groove, so that the central axis of the cylinder is aligned with the symmetrical center line of the two V-shaped clamps, thus completing the initial centering and positioning without the need for repeated manual adjustment of the cylinder position. Then, the clamping cylinder 6 is activated, powered by the hydraulic system. The piston rod of the clamping cylinder 6 extends axially, driving the second V-shaped clamping block 13 at the end to move at a constant speed toward the first V-shaped clamping block 9. Since the clamping cylinder 6 is fixed to the fixing plate 10 by bolts, and the piston rod is coaxial with the central axis of the first V-shaped clamping block 9, the movement trajectory of the second V-shaped clamping block 13 is parallel to the central axis of the cylinder, avoiding skew and squeezing during clamping. After the V-shaped surface of the second V-shaped clamping block 13 is in contact with the outer wall of the cylinder, the clamping cylinder 6 continues to output a stable clamping force, so that the first V-shaped clamping block 9 and the second V-shaped clamping block 13 clamp the cylinder symmetrically from both sides. At this time, the contact area of ​​the V-shaped structure is large, which can evenly distribute the clamping force to the outer wall of the cylinder and avoid local pressure concentration. At the same time, the clamping force can be adjusted through the hydraulic system, which can ensure that the cylinder does not slip and will not cause cylinder deformation or scratches on the outer wall due to excessive pressure. After the cylinder guide sleeve is disassembled and assembled, the piston rod of the clamping cylinder 6 is retracted, and the second V-shaped clamp 13 moves away from the first V-shaped clamp 9, thus widening the clamping gap again. At this time, the cylinder is released from its constraint, and the cylinder can be directly removed from between the two V-shaped clamps, completing a single clamping-releasing cycle.

[0022] In this invention, the position adjustment unit includes a translation mechanism 30 and a lifting mechanism 3. The translation mechanism 30 slides with the clamping unit to achieve horizontal position adjustment. The lifting mechanism 3 is connected between the translation mechanism 30 and the rotary unit 4 and is used to drive the rotary unit 4 to move up and down in the vertical direction. The translation mechanism 30 includes at least two cross sliders 5 and a guide rail 11. The guide rail 11 extends horizontally along the clamping module 2. The cross sliders 5 slide in cooperation with the guide rail 11, and the lifting mechanism 3 is fixedly connected to the cross sliders 5. The guide rail 11 extends horizontally along the clamping module 2, limiting the sliding trajectory of the cross sliders 5, ensuring a unique direction of movement without lateral deviation, and providing a basis for precise horizontal position adjustment. Furthermore, through the matching structure with the cross sliders 5 (such as a groove or wear-resistant bushing), the friction during horizontal movement is reduced, ensuring a smooth and effortless adjustment process. The cross slider 5 supports the lifting mechanism 3 on top and connects to the guide rail 11 on the bottom, establishing a rigid connection between the lifting mechanism 3 and the guide rail 11. This enables the power transmission and position linkage of the guide rail 11 guiding → slider movement → synchronous translation of the lifting mechanism 3. The cross slider 5 slides with the guide rail 11, and through its own groove matching the guide rail 11, it achieves automatic fine adjustment in the horizontal direction, meeting the high precision requirements of coaxial alignment. It adopts a modular design, which facilitates later replacement and maintenance, or adjustment of the number / specification of sliders according to load requirements.

[0023] Preferably, there are four cross sliders 5, which are symmetrically distributed on the guide rails 11 of the clamping module 2. The four cross sliders 5 are divided into two groups and symmetrically distributed on the two guide rails 11 (or on both sides of a single guide rail), so that the load at the bottom of the lifting mechanism 3 is evenly transmitted to each slider and then distributed to the clamping module 2 through the guide rails 11, which completely avoids sliding jamming or structural deformation caused by local overload. The four groups of symmetrical layout form a rectangular support surface, which has a stronger constraint on the lifting mechanism 3. Even if the rotary unit 4 generates rotary torque during operation, it can be offset by the reverse force of the symmetrical sliders, avoiding horizontal vibration or displacement and ensuring the positional stability of the guide sleeve during disassembly and assembly.

[0024] The lifting mechanism 3 includes at least two lifting cylinders 7. The cylinder barrel of the lifting cylinder 7 is fixed to the cross slider 5 by bolts, and the piston rod of the lifting cylinder 7 is fixedly connected to the bottom of the mounting platform of the rotary unit 4 by bolts.

[0025] The lifting cylinder 7 drives the piston rod to extend and retract through the hydraulic system, providing stable and controllable vertical lifting power, replacing manual lifting or padding, and the lifting stroke is precisely adjustable; the cylinder is fixed to the cross slider 5, and the piston rod is connected to the installation platform to form a rigid load-bearing structure, which directly bears the weight of the rotating unit 4 and the reverse force during the disassembly and assembly process, avoiding deformation, and can establish a rigid connection between the lifting mechanism 3 and the translation mechanism 30, so that the translation mechanism 30 drives the lifting mechanism 3 to move horizontally synchronously; Preferably, there are two lifting cylinders 7, which are symmetrically arranged on the cross slider 5. The two cylinders are symmetrically distributed on the cross slider 5 (when there are four sets of cross sliders 5, the cylinders are symmetrically arranged between the two sets of sliders). This ensures that the load of the rotating unit 4 mounting platform is evenly distributed to each cylinder, avoiding deformation of the mounting platform or cylinder jamming caused by local stress concentration. In addition, the symmetrical arrangement ensures that the two cylinders are under the same force, and synchronous extension and retraction can be achieved under the control of the hydraulic system. This ensures that the rotating unit 4 moves in the vertical direction without lateral offset, and ensures the coaxiality of the rotating part 12 and the guide sleeve. Furthermore, during disassembly and assembly, the rotational torque generated by the rotating unit 4 is transmitted to the four supporting columns through the mounting platform. The symmetrical layout of the columns can offset the lateral force brought by the torque, preventing vibration or displacement of the lifting mechanism 3 and ensuring the stability of the guide sleeve disassembly and assembly. When the lifting cylinder 7 is not started, its piston rod is in the retracted state, and the mounting platform of the rotary unit 4 is in the lowest position, ensuring that the rotary unit 4 will not interfere with the placement of the cylinder after the cylinder is placed in the clamping unit; at this time, the cylinders of the two lifting cylinders 7 are firmly fixed to the cross slider 5 by bolts, and the piston rod is connected to the bottom of the mounting platform by bolts to form a complete rigid load-bearing chain. After the translation mechanism 30 completes the horizontal coordinate correction of the rotary unit 4, the hydraulic system is started, and synchronous hydraulic oil is input into the two lifting cylinders 7 (synchronized through the four columns) to ensure that the piston rods of the two cylinders extend at the same time and speed. During the extension and retraction of the piston rod, since the cylinder and the cross slider 5 are rigidly fixed, the vertical extension and retraction power of the piston rod is transmitted to the installation platform through the bolt connection, which drives the rotary unit 4 to rise steadily in the vertical direction. Operators can adjust the piston rod extension length by visual observation or feedback from displacement sensors to align the drive seat of the rotating part 12 (such as a rotary table) of the rotating unit 4 with the preset force height of the disassembly and assembly tool (such as a C-type wrench), or adapt to the height of the guide sleeve of the cylinder to be disassembled or assembled. Once the slewing unit 4 has been raised or lowered to the target height, the hydraulic system stops supplying oil and maintains pressure. The piston rod position is locked by the pressure of the hydraulic oil, keeping the slewing unit 4 at a fixed height. At the same time, the rigid structure of the bolted connection further constrains the displacement of the installation platform, preventing height deviation caused by slewing torque or vibration during operation, and providing a stable height reference for the disassembly and assembly of the guide sleeve. After the cylinder guide sleeve is disassembled and assembled, the hydraulic system is controlled to supply oil in reverse, and the piston rods of the two lifting cylinders 7 retract synchronously, driving the rotary unit 4 to descend to the initial lowest position to avoid interfering with the cylinder picking up the part; after the cylinder is taken out from the clamping unit, the piston rod remains in the retracted state, waiting for the next operation.

[0026] In this invention, the rotary unit 4 includes a driving component 8 and a rotary component 12. The driving component 8 is connected to the rotary component 12 in a transmission manner and is used to drive the rotary component 12 to rotate in both directions. The rotary component 12 is used to cooperate with disassembly and assembly tools to realize the disassembly and assembly of the cylinder guide sleeve. The rotary unit 4 is fixed to the top end face of the installation platform by bolts. Preferably, the driving component 8 is a servo motor. The servo motor outputs uniform torque and runs smoothly without impact power fluctuations, ensuring that the guide sleeve is subjected to force gradually and avoiding the guide sleeve from cracking or deforming due to instantaneous impact. The rotating component 12 is a rotary table. The servo motor is connected to the rotary table for transmission. The servo motor is electrically controlled to rotate forward and backward, thereby driving the rotary table to rotate forward and backward synchronously.

[0027] This invention also provides a method for disassembling and assembling a hydraulic cylinder using a hydraulic cylinder disassembly and assembly tooling, characterized by comprising the following steps: S1: Place the cylinder to be disassembled or assembled in the clamping area of ​​the clamping unit, and drive the clamping components to move towards each other through the clamping unit to disassemble and fix the cylinder barrel. The clamping cylinder of the clamping unit drives the second V-shaped clamping block 13 to approach the first V-shaped clamping block 9. The cylinder barrel is fixed by the relative clamping action of the first V-shaped clamping block 9 and the second V-shaped clamping block 13. The clamping surface increases the friction through the anti-slip rubber layer to prevent the cylinder barrel from sliding or being scratched. S2: The horizontal position of the rotary unit 4 is adjusted by the translation mechanism 30 of the position adjustment unit to realize the relative coordinate correction between the rotary unit 4 and the oil cylinder guide sleeve. Then, the vertical height of the rotary unit 4 is adjusted by the lifting mechanism 3 of the position adjustment unit to make the rotary part 12 of the rotary unit 4 compatible with the disassembly and assembly tools. The translation mechanism 30 adjusts its horizontal position by sliding the cross slider 5 along the guide rail 11 of the clamping module 2, so that the center of the rotating part 12 is coaxially aligned with the center of the cylinder guide sleeve, thus completing automatic coordinate correction and ensuring the coaxiality of disassembly and assembly. S3: Connect one end of the disassembly and assembly tool to the cylinder guide sleeve, and abut the other end to the rotating part 12 of the rotary unit 4. The disassembly and assembly tool is a C-type wrench. The clamping end of the C-type wrench is engaged in the process groove preset in the cylinder guide sleeve, and the force-bearing end of the C-type wrench abuts against the drive seat of the rotating part 12 to form a rigid transmission fit. S4: By electrically controlling the operation of the drive component 8 of the rotary unit 4, the rotary component 12 is driven to rotate in both directions, thereby driving the cylinder guide sleeve to rotate synchronously through the disassembly and assembly tools, so as to realize the disassembly or installation of the cylinder guide sleeve. The forward and reverse rotation direction and output speed of the drive component 8 are set by the electrical control system. The drive component 8 drives the rotating component 12 to rotate smoothly at the preset speed. The rotational power is transmitted to the hydraulic cylinder guide sleeve by the disassembly and assembly tools, so as to achieve precise disassembly or fastening of the guide sleeve. S5: After disassembly and assembly are completed, control the clamping unit to release the cylinder barrel, remove the cylinder, and complete the disassembly and assembly operation.
