Description

Technical Field

[0001] This utility model relates to the technical field of oil control devices, specifically to an oil control device for hydraulic cylinder production and handling. Background Technology

[0002] A hydraulic cylinder is a core hydraulic actuator that efficiently converts hydraulic energy into mechanical energy. It is mainly used to achieve linear reciprocating motion. It not only has the basic advantages of simple structure and reliable operation, but also eliminates the need for additional reduction gears when achieving reciprocating motion. Moreover, it has no transmission backlash and can always maintain a smooth motion state. With these characteristics, hydraulic cylinders are widely used in many fields such as engineering machinery (such as excavators and cranes), industrial production equipment (such as stamping machines and injection molding machines), and agricultural machinery (such as tractors and harvesters), becoming a key component for transmitting power and performing actions in various power equipment.

[0003] In the existing technology, during the production and handling of hydraulic cylinders, the industry typically uses mobile trolleys for transfer operations. However, during loading operations, hydraulic cylinders are often placed directly on the trolley without a dedicated fixing structure. This causes the cylinders to wobble and shift due to road bumps or turns during handling, resulting in poor stability. This not only may cause damage to the cylinders from impacts but also significantly increases the safety risk of them falling. At the same time, during the production process, residual oil inevitably adheres to the inner and outer surfaces of the hydraulic cylinders. The direct placement method lacks a corresponding collection structure, and this oil continues to drip during handling and transfer. It is difficult to collect and recover the dripping oil, which will pollute the workshop floor, increase subsequent cleaning costs, and may also pose a safety hazard to personnel due to slippage caused by the oil. Utility Model Content

[0004] The purpose of this utility model is to provide a hydraulic cylinder production and handling oil control device to solve the problems mentioned in the background art. In the production and handling of hydraulic cylinders, the industry commonly uses mobile trolleys for transfer. However, due to the lack of a dedicated fixing structure, the cylinders are easily deflected during handling due to road bumps or turning, resulting in poor stability. This can lead to damage to the cylinders and significantly increase the risk of them falling. At the same time, residual oil will adhere to the inner and outer surfaces of the cylinders during production. Direct placement without an oil collection structure leads to continuous oil dripping during handling. This makes it difficult to collect and recover the oil, pollutes the workshop floor, increases cleaning costs, and may also cause personnel safety hazards due to oil slippage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic cylinder production and handling oil control device, including a collection frame, a universal brake wheel fixedly connected to the bottom of the collection frame, a filter plate fixedly connected to the inner wall of the collection frame, a drain pipe and a mounting frame fixedly connected to the collection frame, a one-way solenoid valve fixedly connected to the drain pipe, a movable frame slidably connected to the mounting frame, a first drive assembly mounted on the mounting frame, a support frame slidably connected to the movable frame, an oil control assembly mounted between the movable frame and the support frame, a clamping frame slidably connected to the support frame, a second drive assembly mounted on the support frame, a sealing ring fixedly connected to the clamping frame, a clamping pin slidably connected to the clamping frame and the sealing ring, a limiting plate fixedly connected to one end of the clamping pin, and a first spring fixedly connected between the limiting plate and the clamping frame. The limiting plate is slidably connected to the clamping frame. The first drive assembly is used to drive the movable frame to move, the oil control assembly is used to drive the support frame to reciprocate up and down, and the second drive assembly is used to drive the clamping frames on both sides to move closer or further apart.

[0006] In a preferred embodiment of this technical solution, the mounting frame has a sliding groove at a corresponding position on the movable frame, and the movable frame is slidably connected to the sliding groove of the mounting frame.

[0007] In a preferred embodiment of this technical solution, the movable frame has a through slot at a corresponding position on the support frame, and the support frame is slidably connected to the through slot of the movable frame.

[0008] Based on the preferred embodiment of this technical solution, two sets of clamping frames are provided, which are symmetrically distributed on the support frame. The support frame has limit grooves at corresponding positions of the two sets of clamping frames, and the two sets of clamping frames are slidably connected to the limit grooves of the support frame.

[0009] In the preferred embodiment of this technical solution, the clamping frame has a travel groove at the corresponding position of the limiting plate, and the limiting plate is slidably connected to the travel groove of the clamping frame.

[0010] In a preferred embodiment of this technical solution, the first drive assembly includes a first motor fixedly connected to the mounting bracket and a screw rotatably connected to the mounting bracket. A movable bracket is threadedly connected to the screw, and the screw is fixedly connected to the output end of the first motor. The first motor is used to drive the screw to rotate.

[0011] In a preferred embodiment of this technical solution, the second drive assembly includes a second motor fixedly connected to the support frame and a bidirectional threaded rod rotatably connected to the support frame. The bidirectional threaded rod is fixedly connected to the output end of the second motor, and the clamping frame is threadedly connected to the bidirectional threaded rod. The second motor is used to drive the bidirectional threaded rod to rotate.

[0012] According to the preferred embodiment of this technical solution, the oil control component includes a second spring fixedly connected between the support frame and the movable frame, a third motor fixedly connected to the movable frame, a rotating disk fixedly connected to the output end of the third motor, a light rod fixedly connected to the side of the rotating disk away from the third motor, a movable bracket rotatably connected to the light rod at one end, and a base fixedly connected to the support frame. The other end of the movable bracket is rotatably connected to the base, and the third motor is used to drive the rotating disk to rotate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The first drive assembly moves the mobile frame, allowing the support frame to be positioned outside the collection frame, facilitating the placement of the hydraulic cylinder between the two sets of clamping frames and simplifying the cylinder loading operation. The second drive assembly then moves the clamping frames on both sides closer together, with the clamping pins fitting against the outside of the hydraulic cylinder. The first spring drives several sets of clamping pins to adapt to the shape of the hydraulic cylinder, enabling stable clamping of cylinders with different shapes. This effectively prevents the cylinder from shaking or shifting due to road bumps or turning during transportation, significantly improving the transportation stability of the hydraulic cylinder.

[0014] 2. The rotating disk is driven by a third motor, which in turn drives the guide rod to move in a circular motion. The guide rod then pushes the base and support frame to move up and down through a movable bracket. With the help of the second spring, the support frame is reset, enabling the support frame to drive the oil cylinder to move up and down stably. This accelerates the dripping of oil adhering to the surface of the oil cylinder and improves the oil recovery efficiency. Compared with hydraulic or pneumatic drives, this mechanical transmission structure is simpler and more reliable, with lower manufacturing costs. Moreover, the speed of the third motor is adjustable, which can adjust the reciprocating frequency of the support frame according to the oil adhesion in the oil cylinder, adapting to different oil control needs.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 This utility model provides an embodiment of a hydraulic cylinder production and handling oil control device, including a collection frame 1, a universal brake wheel 4 fixedly connected to the bottom of the collection frame 1, a filter plate 7 fixedly connected to the inner wall of the collection frame 1, a drain pipe 5 and a mounting frame 21 fixedly connected to the collection frame 1, a one-way solenoid valve 6 fixedly connected to the drain pipe 5, a movable frame 24 slidably connected to the mounting frame 21, a first drive assembly mounted on the mounting frame 21, a support frame 25 slidably connected to the movable frame 24, an oil control assembly mounted between the movable frame 24 and the support frame 25, a clamping frame 28 slidably connected to the support frame 25, a second drive assembly mounted on the support frame 25, a sealing ring 29 fixedly connected to the clamping frame 28, a clamping pin 210 slidably connected to the clamping frame 28 and the sealing ring 29, a limiting plate 211 fixedly connected to one end of the clamping pin 210, and a limiting plate 211 fixedly connected to the limiting plate. The first spring 212 between 211 and the clamping frame 28, the limiting plate 211 is slidably connected to the clamping frame 28, the first drive assembly is used to drive the moving frame 24 to move, the oil control assembly is used to drive the support frame 25 to move up and down, and the second drive assembly is used to drive the clamping frames 28 on both sides to move closer or further apart. By driving the moving frame 24 to move through the first drive assembly, the support frame 25 can be placed outside the collection frame 1, which makes it convenient to place the hydraulic cylinder between the two sets of clamping frames 28 and simplify the cylinder loading operation. Then, by driving the clamping frames 28 on both sides to move closer together through the second drive assembly, the clamping pins 210 fit against the outside of the hydraulic cylinder, and the first spring 212 drives several sets of clamping pins 210 to adapt to the shape of the hydraulic cylinder, which can achieve stable clamping of cylinders with different shapes, effectively preventing the cylinder from shaking or deviating due to road bumps or turning during transportation, and significantly improving the transportation stability of the hydraulic cylinder.

[0019] Please see Figure 2 A further solution based on this embodiment is as follows: the mounting frame 21 has a groove at the corresponding position of the movable frame 24, and the movable frame 24 is slidably connected to the groove of the mounting frame 21. By opening a groove on the mounting frame 21 and allowing the movable frame 24 to be slidably connected there, the groove can provide a clear and stable trajectory guide for the movement of the movable frame 24, avoiding the situation of the movable frame 24 deviating or getting stuck during the sliding process. This sliding cooperation method can also reduce the frictional wear between the movable frame 24 and the mounting frame 21, extend the service life of the components, and at the same time ensure that when the first drive component drives the movable frame 24 to move, it can accurately drive the support frame 25 and the hydraulic cylinder to the designated position, such as smoothly transferring the hydraulic cylinder from outside the collection frame 1 to the center position inside the frame.

[0020] Please see Figure 3 A further solution based on this embodiment is as follows: the movable frame 24 has a through groove at the corresponding position of the support frame 25, and the support frame 25 is slidably connected to the through groove of the movable frame 24. By opening a through groove on the movable frame 24 and allowing the support frame 25 to be slidably connected here, the through groove can restrict the movement direction of the support frame 25, ensuring that the support frame 25 only moves up and down along the through groove and will not have lateral deviation. This structural design allows the oil control component to drive the support frame 25 to move more stably, thereby driving the oil cylinder to shake up and down, and preventing the oil cylinder from tilting or colliding due to the deviation of the support frame 25.

[0021] Please see Figure 3 A further solution based on this embodiment is as follows: two sets of clamping frames 28 are provided, and the two sets of clamping frames 28 are symmetrically distributed on the support frame 25. The support frame 25 has limit grooves at corresponding positions of the two sets of clamping frames 28. The two sets of clamping frames 28 are slidably connected to the limit grooves of the support frame 25. By symmetrically distributing the two sets of clamping frames 28 on the support frame 25 and allowing them to be slidably connected to the limit grooves of the support frame 25, the symmetrical structure can make the clamping force of the two sets of clamping frames 28 on the hydraulic cylinder more uniform, avoiding the hydraulic cylinder from tilting or being damaged due to excessive force on one side. The limit grooves can provide a stable trajectory for the sliding of the clamping frames 28, ensuring that when the second drive component drives the two sets of clamping frames 28 to move closer or further away from each other, the two movements are synchronized and the spacing is precisely adjusted, which can adapt to hydraulic cylinders of different diameters and improve the versatility of the device.

[0022] Please see Figure 4A further solution based on this embodiment is as follows: the clamping frame 28 has a stroke groove at the corresponding position of the limiting plate 211, and the limiting plate 211 is slidably connected to the stroke groove of the clamping frame 28. By opening the stroke groove on the clamping frame 28 and allowing the limiting plate 211 to be slidably connected here, the stroke groove can clearly limit the movement range of the limiting plate 211, preventing the limiting plate 211 from sliding excessively under the elastic force of the first spring 212, causing the clamping pin 210 to disengage from the preset working position; at the same time, the stroke groove can provide a stable sliding space for the limiting plate 211, ensuring that when the limiting plate 211 drives the clamping pin 210 to adhere to the surface of the oil cylinder, the clamping pin 210 can always maintain effective contact with the oil cylinder, and there will be no loosening of the clamping due to the offset of the limiting plate 211, further improving the clamping stability of the oil cylinder.

[0023] Please see Figure 2 A further solution based on this embodiment is as follows: The first drive assembly includes a first motor 23 fixedly connected to the mounting frame 21 and a screw 22 rotatably connected to the mounting frame 21. The movable frame 24 is threadedly connected to the screw 22. The screw 22 is fixedly connected to the output end of the first motor 23. The first motor 23 is used to drive the screw 22 to rotate. By driving the screw 22 to rotate through the first motor 23, the rotational motion of the motor is converted into the linear motion of the movable frame 24 by utilizing the threaded connection between the screw 22 and the movable frame 24. This transmission method can accurately control the moving speed and distance of the movable frame 24, which is more efficient and has less error than manual adjustment. At the same time, the screw 22 transmission has self-locking property. When the first motor 23 stops working, the movable frame 24 can stably stay in the current position and will not slide on its own due to the weight of the cylinder or road bumps, ensuring the stability of the cylinder during transportation and reducing the risk of falling.

[0024] Please see Figure 3 A further solution based on this embodiment is as follows: The second drive assembly includes a second motor 27 fixedly connected to the support frame 25 and a bidirectional threaded rod 26 rotatably connected to the support frame 25. The bidirectional threaded rod 26 is fixedly connected to the output end of the second motor 27, and the clamping frame 28 is threadedly connected to the bidirectional threaded rod 26. The second motor 27 is used to drive the bidirectional threaded rod 26 to rotate. By driving the bidirectional threaded rod 26 to rotate through the second motor 27, the thread directions at both ends of the bidirectional threaded rod 26 are opposite, which can drive the two sets of threaded clamping frames 28 to move closer or further away from each other synchronously. This design eliminates the need to control the two sets of clamping frames 28 separately, simplifying the drive structure and improving the clamping adjustment efficiency. At the same time, the bidirectional threaded rod 26 has high transmission accuracy and can accurately control the distance between the two sets of clamping frames 28, ensuring that the clamping force for cylinders of different diameters is moderate, avoiding both excessively loose clamping that causes cylinder shaking and excessively tight clamping that damages the cylinder surface.

[0025] Please see Figure 5A further solution based on this embodiment is as follows: the oil control assembly includes a second spring 31 fixedly connected between the support frame 25 and the movable frame 24, a third motor 32 fixedly connected to the movable frame 24, a rotating disk 33 fixedly connected to the output end of the third motor 32, a smooth rod 34 fixedly connected to the side of the rotating disk 33 away from the third motor 32, a movable bracket 36 rotatably connected at one end to the smooth rod 34, and a base 35 fixedly connected to the support frame 25. The other end of the movable bracket 36 is rotatably connected to the base 35. The third motor 32 is used to drive the rotating disk 33 to rotate. The rotating disk 33 drives the guide rod 34 to rotate in a circular motion. The guide rod 34 then pushes the base 35 and the support frame 25 up and down through the movable bracket 36. With the help of the elastic force of the second spring 31, the support frame 25 returns to its original position, enabling the support frame 25 to drive the oil cylinder to move up and down stably. This accelerates the dripping of oil adhering to the surface of the oil cylinder and improves the oil recovery efficiency. Compared with hydraulic or pneumatic drive, this mechanical transmission structure is simpler and more reliable, with lower manufacturing costs. In addition, the speed of the third motor 32 is adjustable, which can adjust the reciprocating frequency of the support frame 25 according to the oil adhesion in the oil cylinder to adapt to different oil control requirements.

[0026] Working principle: First, the first motor 23 in the first drive assembly is started. The first motor 23 drives the screw 22 on the mounting frame 21 to rotate. Because the movable frame 24 is threadedly connected to the screw 22 and slides along the slide groove of the mounting frame 21, the movable frame 24 will slide to the outside of the collection frame 1 as the screw 22 rotates, making it convenient for the operator to place the hydraulic cylinder to be transported between the two sets of clamping frames 28. Then, the second motor 27 in the second drive assembly is started. The second motor 27 drives the bidirectional threaded rod 26 on the support frame 25 to rotate. Since the two sets of clamping frames 28 are symmetrically distributed and threadedly connected to the bidirectional threaded rod 26, and slide along the limiting groove of the support frame 25, the rotation of the bidirectional threaded rod 26 will cause the two sets of clamping frames 28 to move closer to each other synchronously. At this time, the clamping pins 210 on the clamping frame 28 contact the outer wall of the hydraulic cylinder, the limiting plate 211 slides in the stroke groove of the clamping frame 28, the first spring 212 is compressed and generates a reverse elastic force, causing several sets of clamping pins 210 to adapt to the shape of the hydraulic cylinder, and at the same time, the sealing rings 29 on the clamping frame 28 reduce Oil seeps out from the contact gaps, securing the hydraulic cylinder firmly. Then, the first motor 23 is restarted, causing the moving frame 24 to reset along the slide groove, moving the hydraulic cylinder to the center position of the collection frame 1 to prevent cylinder displacement during transport. Next, the third motor 32 in the oil control assembly is started, driving the rotating disk 33 to rotate. The guide rod 34 on the rotating disk 33 moves in a circular motion, pushing the base 35 fixed to the support frame 25 via the movable bracket 36, causing the support frame 25 to move along the moving frame. The through groove of 24 moves up and down reciprocally. The second spring 31 between the moving frame 24 and the support frame 25 assists the support frame 25 to reset and accelerates the dripping of oil adhering to the surface of the hydraulic cylinder. The dripping oil falls into the collection frame 1, and after being filtered by the filter plate 7, it is temporarily stored. When it is necessary to recover the oil, the one-way solenoid valve 6 on the drain pipe 5 can be opened to discharge the filtered oil. The universal brake wheel 4 at the bottom of the collection frame 1 can realize the flexible movement and positioning of the device, ensuring the stable handling of the hydraulic cylinder and the efficient recovery of oil throughout the process.

[0027] 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.
