Description

Technical Field

[0001] This application relates to the technical field of hydraulic pump structures, and in particular to a novel integral housing structure. Background Technology

[0002] In the current design of the K-series hydraulic pump, the integrated structure of the housing and the rocker seat is the core component for achieving variable control and pressure support. Its assembly accuracy is directly related to the sealing performance and working efficiency of the pump body.

[0003] In the existing modular assembly mode, the operator needs to align and fit the independently manufactured rocker seat with the built-in annular groove of the housing through its ear-shaped structure, adjust it to the preset angle by rotation, insert the positioning pin and install the O-ring seal to complete the fixation and sealing.

[0004] Regarding the aforementioned technologies, if the assembly process of the rocker seat and the housing adopts the aforementioned split-part assembly and multi-accessory fixing operation mode, high-precision grinding of the contact surfaces is required to ensure the sealing and alignment of the mating surfaces, and strict control of the assembly gap is necessary. This operation mode is complex, highly dependent on the machining accuracy of the parts, and because the mating gap is difficult to control precisely, it is prone to sealing failure or abnormal wear of the friction pair. Therefore, it has technical defects such as low hydraulic pump assembly efficiency and insufficient sealing reliability. Summary of the Invention

[0005] To improve the assembly efficiency and sealing reliability of hydraulic pumps, this application provides a novel integral housing structure.

[0006] The novel integral shell structure provided in this application adopts the following technical solution: A novel integral shell structure includes a shell, which is a one-piece cast structure. An arc-shaped rocker support structure for cooperating with a rocker is directly cast inside the shell. The arc-shaped rocker support structure has mounting holes. A bearing is disposed inside the shell, which is adapted to the arc-shaped rocker support structure. A fixing component for fixing the bearing is provided at the mounting holes.

[0007] By adopting the above technical solution, the shell is integrally cast, with the arc-shaped rocker seat support structure directly cast inside. This eliminates the need for separate manufacturing and assembly of the rocker seat, reducing the number of parts and assembly steps, and significantly improving assembly efficiency. Simultaneously, the integral structure avoids the fitting clearance issues associated with split-assembly, enhancing sealing reliability. The bearing bush is fixed to the support structure via a fixing component, facilitating installation, and its compatibility with the support structure ensures the smoothness of the rocking motion.

[0008] Optionally, the bearing bush is made of copper.

[0009] By adopting the above technical solutions, copper material has good wear resistance and friction reduction properties, which can extend the service life of bearing bushes and reduce frictional loss.

[0010] Optionally, a positioning rod is fixed on the side of the bearing facing the mounting hole, and the positioning rod is inserted into and adapted to the mounting hole.

[0011] By adopting the above technical solution, the insertion and engagement of the positioning rod and the mounting hole can achieve rapid alignment between the bearing bush and the arc-shaped rocker seat support structure, providing precise positioning for the installation of the bearing bush, avoiding misalignment during installation, ensuring the compatibility between the bearing bush and the arc-shaped rocker seat support structure, and at the same time helping to improve the structural stability after the bearing bush is installed.

[0012] Optionally, the positioning rod has a fixing groove on the side wall away from the bearing bush, and the housing has a moving groove on the side wall of the mounting hole, the length direction of the moving groove being perpendicular to the length direction of the mounting hole; the fixing component includes a fixing block and a first spring, the fixing block is slidably disposed in the moving groove, and the end of the fixing block is inserted into and adapted to the fixing groove; the first spring is fixed between the fixing block and the bottom wall of the moving groove, and is always in a stretched state; the moving groove is also provided with a moving component for driving the fixing block to move toward the mounting hole.

[0013] By adopting the above technical solution, during the bearing bush positioning and installation, the positioning rod is first accurately inserted into the mounting hole to complete the initial positioning of the bearing bush. Then, the moving component is activated, driving the fixing block to move along the moving groove towards the mounting hole. During this process, the first spring is further stretched, allowing the end of the fixing block to smoothly insert into the fixing groove, thereby achieving the snap-fit ​​fixing of the positioning rod and completing the stable installation of the bearing bush. This fixing method achieves rapid snap-fit ​​through the cooperation of the mechanical structure, making it convenient to operate and ensuring reliable connection.

[0014] Optionally, the outer surface of the housing is provided with a mounting groove, and the housing is provided with a sliding groove on one side wall of the moving groove. The length direction of the sliding groove is parallel to the length direction of the mounting hole, and the end of the sliding groove away from the moving groove is connected to the mounting groove. The moving component includes a push plate and a push rod. The push plate is slidably disposed in the mounting groove, and the push rod is disposed in the sliding groove. One end of the push rod is fixedly connected to the push plate. The side of the fixing block facing the sliding groove is provided with a push groove, and the side of the push rod near the moving groove is set as an inclined surface. The push rod is inserted and adapted to the push groove.

[0015] By adopting the above technical solution, the push plate is pushed to slide in the mounting groove, and the push plate drives the push rod to move along the slide groove. The inclined surface of the push rod cooperates with the push groove, and the pushing action of the inclined surface drives the fixed block to slide along the moving groove towards the mounting hole, thereby achieving precise driving of the fixed block. The structure is ingeniously designed and the transmission is smooth. The slide groove guides the movement of the push rod, ensuring the accuracy of the push rod's movement direction, thereby ensuring the movement accuracy of the fixed block and improving the working reliability of the fixing component.

[0016] Optionally, a sealing gasket is fixed to the side of the push plate facing the bottom wall of the placement groove.

[0017] By adopting the above technical solution, the sealing gasket can fill the gap between the push plate and the bottom wall of the mounting groove, thereby sealing the mounting groove and preventing hydraulic oil from leaking from the gap in the mounting groove. At the same time, it prevents external dust and impurities from entering the moving groove and mounting hole, preventing parts from jamming or wearing, and further improving the sealing performance of the housing and the working stability of the internal components.

[0018] Optionally, the housing is rotatably connected to a rotating plate at the opening end of the mounting groove, and the rotating plate is parallel to the push plate; a first push block is fixedly provided on the side of the rotating plate facing the push plate, and a second push block is fixedly provided on the side of the push plate facing the rotating plate. Both the first push block and the second push block are arc-shaped, and one side of both is set as an inclined surface. The inclined surface of the first push block matches the inclined surface of the second push block.

[0019] By adopting the above technical solution, the rotating plate rotates and the first push block rotates synchronously with the rotating plate. The inclined surface of the first push block and the second push block is used to generate a pushing force, which drives the push plate to slide in the mounting groove, realizing the indirect driving of the moving component. The operation method is simple and the driving action can be completed without direct contact with the push plate. The arc-shaped push block, combined with the inclined surface transmission, can make the pushing process more stable and reduce the impact loss between components.

[0020] Optionally, an operating plate is fixedly provided on the side of the rotating plate away from the push plate, and the operating plate is arranged perpendicular to the rotating plate.

[0021] By adopting the above technical solution, the control panel provides a force point for the rotation of the rotating plate. Operators can easily rotate the plate by moving the control panel, increasing the operating lever arm, reducing the difficulty of operation, and improving the ease of operation for installing and removing bearing bushes.

[0022] Optionally, the second push block has a plug-in slot on the side facing the rotating plate, and the rotating plate has a plug-in rod. The length direction of the plug-in rod is perpendicular to the rotating plate. One end of the plug-in rod passes through the rotating plate and the first push block and is slidably connected to both. The plug-in rod is plugged into and adapted to the plug-in slot.

[0023] By adopting the above technical solution, when the rotating plate rotates to the point where the first pusher block drives the pusher plate to complete the pushing action of the fixing block, the sliding insertion rod is inserted into the insertion slot, which can realize the relative fixation of the rotating plate and the pusher plate. This prevents the rotating plate from rotating due to vibration during the operation of the hydraulic pump, avoids the pusher plate from moving back and causing the fixing block to loosen, and ensures the working stability of the fixing component. The sliding cooperation between the insertion rod and the rotating plate and the first pusher block realizes the flexible movement of the insertion rod, which facilitates the quick completion of fixing and unlocking operations.

[0024] Optionally, an auxiliary plate is fixedly provided at the end of the plug rod away from the first push block, and a second spring is fixedly provided between the auxiliary plate and the rotating plate, the second spring being sleeved on the plug rod.

[0025] By adopting the above technical solution, the auxiliary plate provides a force point for the sliding of the plug rod, making it convenient for the operator to pull the plug rod; the second spring always provides elastic force to the plug rod towards the plug groove, ensuring that the plug rod and the plug groove are always tightly connected and preventing the plug rod from loosening.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The housing is made of one piece of casting, and the arc-shaped rocker seat support structure is directly cast inside, eliminating the cumbersome assembly process of the split rocker seat such as alignment and fitting. With the quick positioning and fixing structure of the positioning rod and fixing components, the assembly process of the bearing and hydraulic pump is greatly simplified, the operation difficulty is reduced, and the overall assembly efficiency is improved. 2. The integrated structure eliminates the gap between the housing and the rocker seat, avoiding sealing failure caused by gaps from the structural source; the design of the sealing gasket and plug-in fixing further improves the sealing performance of the housing, prevents hydraulic oil leakage, and ensures the sealing reliability of the hydraulic pump. 3. Copper bearings reduce frictional loss and have good thermal conductivity, reducing component wear and overheating damage; the fixing assembly securely fixes the bearings through the continuous force of the spring, and the cooperation between the plug rod and the second spring prevents components from loosening due to vibration, ensuring the working stability of the bearings and hydraulic pump, and extending the service life of the overall equipment.

[0029] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0030] This application discloses a novel integral shell structure.

[0031] refer to Figure 1 A novel integral shell structure 1 includes a shell 1, which is a cast iron structure integrally cast, with high structural strength and good overall formability. An arc-shaped rocker seat support structure for cooperating with the rocker is directly cast inside the shell 1. The arc-shaped rocker seat support structure and the shell 1 are integrally cast, with no separate fitting gap.

[0032] The one-piece casting design makes the shell 1 and the arc-shaped rocker seat support structure form a whole, completely eliminating the assembly process of the traditional split structure. There is no need to perform separate alignment, grinding and sealing treatment on the shell 1 and the rocker seat, thus eliminating the sealing risks caused by the fit gap from the structural source.

[0033] refer to Figure 2 , Figure 3 and Figure 4 The housing 1 has a mounting hole 12 on the arc-shaped rocker seat support structure. The mounting hole 12 is a cylindrical through hole. A bearing 13 is provided on the inner side of the arc-shaped rocker seat support structure. The bearing 13 is made of tin bronze and has excellent friction reduction, wear resistance and thermal conductivity. The outer arc surface of the bearing 13 is adapted to the inner arc surface of the arc-shaped rocker seat support structure, so that the bearing 13 and the arc-shaped rocker seat support structure can be tightly fitted together.

[0034] The precise fit between the tin bronze bearing 13 and the arc-shaped rocker seat support structure allows for the even distribution of rotational forces during rocking motion, reducing localized stress concentration and frictional resistance, thus improving the smoothness of the hydraulic pump's operation. refer to Figure 2 , Figure 3 and Figure 4A positioning rod 3 is welded and fixed to the side of the bearing bush 13 facing the mounting hole 12. The positioning rod 3 is a cylindrical structure, and its outer diameter is adapted to the inner diameter of the mounting hole 12. A fixing groove 31 is formed on the side wall of the end of the positioning rod 3 away from the bearing bush 13. The fixing groove 31 is a rectangular groove. A moving groove 14 is formed on the side wall of the housing 1 in the mounting hole 12. The length direction of the moving groove 14 is perpendicular to the length direction of the mounting hole 12. A fixing component 2 for fixing the bearing bush 13 is provided in the moving groove 14.

[0035] During the installation of the bearing bush 13, the insertion and engagement of the positioning rod 3 with the mounting hole 12 enables the bearing bush 13 to be quickly initially positioned. The operator only needs to align the positioning rod 3 with the mounting hole 12 and insert it, so that the outer arc surface of the bearing bush 13 is automatically aligned with the inner arc surface of the arc-shaped rocker seat support structure. There is no need to repeatedly adjust the position of the bearing bush 13, which greatly improves the installation and positioning efficiency of the bearing bush 13. The positions of the fixing groove 31 and the moving groove 14 correspond to each other, providing a precise matching position for the subsequent snap-fit ​​fixing of the fixing component 2, ensuring that the fixing component 2 can effectively limit the positioning rod 3.

[0036] refer to Figure 2 , Figure 3 and Figure 4 The fixing component 2 includes a fixing block 21 and a first spring 22. The fixing block 21 is a rectangular block structure that is slidably disposed in the moving groove 14. The end of the fixing block 21 near the mounting hole 12 can be inserted and fitted into the fixing groove 31 to complete the snap-fit ​​fixing of the positioning rod 3. One end of the first spring 22 is welded and fixed to the side of the fixing block 21 away from the mounting hole 12, and the other end is welded and fixed to the inner bottom wall of the moving groove 14. The first spring 22 is always in a stretched state and can drive the fixing block 21 to move into the moving groove 14 through its own tensile rebound force. The moving groove 14 is provided with a moving component 4 on the side away from the mounting hole 12 for driving the fixing block 21 to move toward the mounting hole 12.

[0037] Before the bearing bush 13 is positioned and installed, the fixing block 21 is in the moving groove 14. After the positioning rod 3 is inserted into the mounting hole 12, the moving component 4 pushes the fixing block 21 toward the mounting hole 12. The first spring 22 is stretched again, and the end of the fixing block 21 away from the first spring 22 is engaged in the fixing groove 31, thus securing the positioning rod 3 and fixing the bearing bush 13, making it difficult for the bearing bush 13 to move freely within the housing 1. When replacing the bearing bush 13, the moving component 4 resets, the first spring 22 contracts, and the fixing block 21 moves toward the moving groove 14. The fixing block 21 and the fixing groove 31 disengage, releasing the fixation of the positioning rod 3 and thus the fixation of the bearing bush 13, allowing the bearing bush 13 to be removed from the housing 1.

[0038] refer to Figure 2 , Figure 3 and Figure 4 The outer surface of the housing 1 is provided with a mounting groove 15. The housing 1 is provided with a sliding groove 16 on one side wall of the moving groove 14. The length direction of the sliding groove 16 is parallel to the length direction of the mounting hole 12. The end of the sliding groove 16 away from the moving groove 14 is connected to the mounting groove 15. The sliding groove 16 is a rectangular through groove.

[0039] The movable component 4 includes a push plate 41 and a push rod 42. The push plate 41 is slidably disposed in the mounting groove 15. A rubber sealing gasket 5 is bonded to the side of the push plate 41 facing the bottom wall of the mounting groove 15. The sealing gasket 5 can completely cover the mating surface between the push plate 41 and the bottom wall of the mounting groove 15, thereby sealing the mounting groove 15. The push rod 42 is a rectangular rod structure, disposed in the sliding groove 16 and slidably adapted to the sliding groove 16. One end of the push rod 42 is welded and fixed to the push plate 41, and the other end extends into the movable groove 14. The side of the push rod 42 near the movable groove 14 is set as an inclined surface. The fixed block 21 has a push groove 211 on the side facing the sliding groove 16. The push groove 211 is an inclined groove adapted to the inclined surface of the push rod 42. The push rod 42 can be inserted and adapted to the push groove 211, and the fixed block 21 is moved by the pushing action of the inclined surface.

[0040] When the fixed block 21 needs to be moved, the push plate 41 is pushed to slide in the mounting groove 15. The push plate 41 will drive the push rod 42 to move linearly along the slide groove 16. The slide groove 16 provides precise guidance for the movement of the push rod 42 and prevents the push rod 42 from deviating. After the inclined surface of the push rod 42 contacts the inclined surface of the push groove 211, it will convert the horizontal thrust of the push plate 41 into a vertical thrust that drives the fixed block 21 to move towards the mounting hole 12, realizing efficient power transmission and pushing the fixed block 21 to slide smoothly. The rubber sealing gasket 5 will move synchronously with the push plate 41. After the push plate 41 moves to the set position, the sealing gasket 5 and the bottom wall of the mounting groove 15 are tightly fitted, effectively preventing hydraulic oil from leaking from the connection between the slide groove 16 and the mounting groove 15. At the same time, it prevents external dust and impurities from entering the mounting groove 15 and entering the moving groove 14 through the slide groove 16, avoiding impurities from causing the fixed block 21 or the push rod 42 to jam, and ensuring the smooth operation of the moving component 4 and the fixed component 2.

[0041] refer to Figure 2 , Figure 3 and Figure 4A rotating plate 6 is rotatably connected to the opening end of the housing 1 in the mounting slot 15. The rotating plate 6 is parallel to the push plate 41. An operating plate 62 is welded and fixed to the side of the rotating plate 6 away from the push plate 41. The operating plate 62 is perpendicular to the rotating plate 6, forming an "L" shape, which facilitates the operator to apply force to move the rotating plate 6. A first push block 61 is welded and fixed to the side of the rotating plate 6 facing the push plate 41, and a second push block 7 is welded and fixed to the side of the push plate 41 facing the rotating plate 6. Both the first push block 61 and the second push block 7 are arc-shaped block structures, and both have inclined surfaces on their adjacent sides. The two inclined surfaces fit together, and a pushing force can be generated by the relative sliding of the inclined surfaces.

[0042] When the operator drives the push plate 41 to move, there is no need to directly contact the push plate 41. The operator only needs to turn the operating plate 62 by hand to drive the rotating plate 6 to rotate. The "L"-shaped operating plate 62 increases the operating lever arm and reduces the difficulty of the operator to apply force. When the rotating plate 6 rotates, it will drive the first push block 61 to rotate synchronously. The inclined surface of the first push block 61 and the inclined surface of the second push block 7 slide against each other. By utilizing the transmission characteristics of the curved inclined surface, the rotational force of the rotating plate 6 is smoothly converted into a horizontal thrust that pushes the push plate 41 to slide in the mounting groove 15. There is no rigid impact in the transmission process, which reduces the wear between parts and makes the moving speed and distance of the push plate 41 easier to control.

[0043] refer to Figure 2 , Figure 3 and Figure 4 The second pusher 7 has an insertion groove 71 on the side facing the rotating plate 6. The insertion groove 71 is a cylindrical groove. The rotating plate 6 is provided with an insertion rod 63. The insertion rod 63 is a cylindrical structure, and its length direction is perpendicular to the rotating plate 6. One end of the insertion rod 63 passes through the rotating plate 6 and the first pusher 61 in sequence, and is slidably connected to both the rotating plate 6 and the first pusher 61. The end of the insertion rod 63 away from the rotating plate 6 can be inserted and matched with the insertion groove 71 to complete the relative fixation of the rotating plate 6 and the pusher 41. An auxiliary plate 8 is welded and fixed to the end of the insertion rod 63 away from the first pusher 61. The auxiliary plate 8 is a circular plate structure. A second spring 9 is provided between the auxiliary plate 8 and the rotating plate 6. The second spring 9 is sleeved on the outside of the insertion rod 63. One end of the second spring 9 is welded and fixed to the auxiliary plate 8, and the other end is welded and fixed to the rotating plate 6. The second spring 9 is sleeved on the outside of the insertion rod 63.

[0044] When the rotating plate 6 rotates to the point where the first push block 61 drives the push plate 41 to complete the pushing action of the fixing block 21, the operator only needs to release the auxiliary plate 8. The contraction of the second spring 9 drives the plug rod 63 to slide quickly towards the push plate 41, so that the end of the plug rod 63 is accurately inserted into the plug groove 71, thereby achieving relative fixation between the rotating plate 6 and the push plate 41. This prevents the rotating plate 6 from reversing due to vibration during the operation of the hydraulic pump, and thus avoids the push plate 41 from moving back and causing the fixing block 21 to loosen. When it is necessary to disassemble the bearing bush 13, the operator only needs to pull the auxiliary plate 8 to pull the plug rod 63 out of the plug groove 71, thereby releasing the fixation between the rotating plate 6 and the push plate 41. The operation is convenient. The auxiliary plate 8 provides a convenient force application point for the sliding of the plug rod 63, avoiding direct contact with the plug rod 63 by the operator and causing hand injuries, while ensuring the smooth sliding of the plug rod 63.

[0045] The implementation principle of the novel integral housing 1 structure in this application embodiment is as follows: When assembling the bearing bush 13, the bearing bush 13 is first placed into the housing 1, and the positioning rod 3 is inserted into the mounting hole 12 to achieve initial positioning. Then, by rotating the rotating plate 6 through the operating plate 62, the inclined surface of the first push block 61 pushes the inclined surface of the second push block 7, causing the push plate 41 to move into the mounting groove 15. The push rod 42 moves accordingly, and its inclined surface pushes the fixing block 21 to move towards the mounting hole 12 until the end of the fixing block 21 is inserted into the fixing groove 31 on the positioning rod 3, thus completing the locking of the bearing bush 13. At this time, the insertion rod 63 automatically inserts into the insertion groove 71 under the action of the second spring 9, preventing the rotating plate 6 from rotating back and ensuring stable locking. When it is necessary to disassemble the bearing bush 13, the auxiliary plate 8 is pulled to make the insertion rod 63 exit the insertion groove 71, the rotating plate 6 is rotated in the opposite direction, the push plate 41 and the push rod 42 are reset, and the fixing block 21 exits the fixing groove 31 under the pull of the first spring 22, and the bearing bush 13 can be removed. The entire process is simple and quick, effectively improving the assembly efficiency and sealing reliability of the hydraulic pump.

[0046] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
