Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of hole machining technology, and more specifically, to a bushing oil hole machining apparatus. Background Technology

[0002] In the field of machining, bushings are common parts, and the quality and efficiency of their oil hole machining have a significant impact on equipment performance. The oil holes in bushings are mainly used for the flow of lubricating oil, ensuring proper lubrication and cooling of equipment components and guaranteeing stable operation of the mechanical system. Traditional bushing oil hole machining often uses single-drill equipment, requiring workers to operate the equipment sequentially to drill each oil hole location on the bushing. This method has many drawbacks. For example, single-drill equipment has extremely low machining efficiency, and when faced with a large number of bushing oil hole machining tasks, the production cycle is significantly prolonged.

[0003] In existing technologies, multi-drill-bit machining equipment has emerged to address the shortcomings of traditional single-drill-bit machining equipment. Multi-drill-bit machining equipment integrates multiple drill bits on the same worktable, allowing simultaneous drilling of multiple oil hole locations on bushings. This equipment significantly improves the efficiency of bushing oil hole machining and shortens the production cycle. However, current multi-drill-bit machining equipment still faces some problems in its application to bushing oil hole machining. For example, when replacing or maintaining drill bits, direct operation is often inconvenient due to space constraints. Often, the entire mounting base of the drilling rig must be removed before replacing the drill bit, and then the entire rig must be reinstalled on the worktable. Alternatively, the mounting base needs to be periodically disassembled for maintenance of the drive mechanism or cleaning of debris stuck in the gaps. The drilling rig mounting base is usually fixed to the worktable with bolts and nuts, and installing and removing bolts is time-consuming and laborious, making the operation cumbersome and inconvenient. Therefore, it is necessary to improve the existing installation method of the mounting base to solve the problems of cumbersome and inconvenient operation. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a bushing oil hole processing device, which solves the technical problems of cumbersome installation and disassembly of the mounting base and inconvenient operation in the related art.

[0005] According to one aspect, at least one embodiment of this disclosure provides a bushing oil hole machining apparatus, including a worktable and a workpiece fixture and a mounting base disposed on the worktable, with drilling rigs disposed on the mounting base, and multiple drilling rigs arranged circumferentially spaced around the workpiece fixture, the bushing oil hole machining apparatus further comprising:

[0006] A card is provided on the worktable, and the card has a card slot.

[0007] A locking assembly is provided, wherein the mounting base has a through hole, the locking assembly is disposed on the inner wall of the through hole, the locking assembly has a limiting groove, and the locking assembly is used to lock the clip;

[0008] The first limiting component is movable and disposed within the limiting groove. After the first limiting component moves, it is used to engage or disengage within the engaging groove.

[0009] For example, at least one embodiment of this disclosure provides a bushing oil hole machining apparatus, wherein the locking assembly includes:

[0010] The outer shell is hollow inside and is disposed on the mounting base, located within the through hole;

[0011] A movable component is vertically movable within the housing. The limiting groove is located on the movable component. The movable component also has a receiving groove communicating with the limiting groove. The receiving groove is used to receive the locking component. The movable component is arranged such that after it moves, it drives the limiting component to engage in the locking groove under the limiting of the inner wall of the housing, or after it moves, it drives the limiting component to move along the inner wall of the locking groove and retract into the limiting groove.

[0012] For example, at least one embodiment of this disclosure provides a bushing oil hole processing device, wherein the limiting member is spherical, the size of the limiting groove near the receiving groove is smaller than the diameter of the limiting member, and gradually widens from this end to the other end, the size of the other end is greater than or equal to the diameter of the limiting member.

[0013] For example, in at least one embodiment of this disclosure, a bushing oil hole machining apparatus is provided, wherein the locking assembly further includes:

[0014] An elastic element, with one end acting on the outer shell and the other end acting on the movable element, is used to provide a force for the movable element to drive the limiting element into the locking groove.

[0015] For example, in at least one embodiment of this disclosure, a bushing oil hole machining apparatus is provided, wherein the moving member further has a guide groove, and the locking assembly further includes:

[0016] The pressing element is movably disposed within the housing and located above the movable element;

[0017] A baffle is disposed on the inner wall of the outer casing, located on one side of the movable component, and the pressing component, the outer casing, the movable component, and the baffle form a limiting space;

[0018] The second limiting member is located within the limiting space. After the pressing member moves, it pushes the second limiting member to squeeze the guide groove, causing the moving member to move and drive the first limiting member to disengage from the snap-fit ​​groove.

[0019] For example, at least one embodiment of this disclosure provides a bushing oil hole processing device, wherein the pressing member has a guide surface that abuts against the limiting member two.

[0020] For example, at least one embodiment of this disclosure provides a bushing oil hole processing device, wherein the pressing member has a groove, the moving member has a retaining edge, the retaining edge is located in the groove, and the retaining edge is used to limit the moving member by engaging with the inner wall of the groove.

[0021] For example, at least one embodiment of this disclosure provides a bushing oil hole processing apparatus, wherein the top of the pressing member extends outside the housing.

[0022] For example, at least one embodiment of this disclosure provides a bushing oil hole processing device, wherein the limiting member two is spherical.

[0023] For example, at least one embodiment of this disclosure provides a bushing oil hole processing device, wherein the second limiting member, the baffle, and the first limiting member are all symmetrically distributed in two along the moving member.

[0024] The beneficial effects of the embodiments disclosed herein are as follows:

[0025] This disclosure simplifies installation and disassembly operations: through the cooperation of clamps, locking components, and limiting components, the traditional bolt and nut fixing method is eliminated. Installing and disassembling the mounting base only requires moving the limiting component to engage or disengage it from the locking groove, making the operation simple and quick, greatly saving installation and disassembly time, improving work efficiency, and solving the problem of cumbersome operation. It also facilitates maintenance and component replacement: when it is necessary to replace the drill bit, maintain the drive mechanism, or clean up waste, the mounting base can be quickly removed from the worktable, avoiding operational inconvenience caused by space constraints. This makes the maintenance and replacement of internal components of the drilling rig and mounting base easier, reducing equipment downtime and improving equipment utilization.

[0033] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components.

[0036] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0037] like Figures 1-3 The diagram illustrates a bushing oil hole machining apparatus according to an embodiment of the present disclosure. It includes a worktable 1, a workpiece fixture 2 and a mounting base 3 disposed on the worktable 1, and a drilling rig 4 disposed on the mounting base 3. Multiple drilling rigs 4 are arranged circumferentially around the workpiece fixture 2, allowing for simultaneous drilling of multiple holes. The bushing oil hole machining apparatus further includes: a clamping member 5 disposed on the worktable 1, the clamping member 5 having a locking groove 6; a through hole 8 on the mounting base 3, a locking assembly 7 disposed on the inner wall of the through hole 8, the locking assembly 7 having a limiting groove 9, the locking assembly 7 being used to lock the clamping member 5; and a limiting member 10 movably disposed within the limiting groove 9, the limiting member 10 being used to engage or disengage from engagement within the locking groove 6 after movement.

[0038] In some examples, the worker first places the bushing to be processed on the workpiece fixture 2 of the worktable 1, and the workpiece fixture 2 firmly fixes the bushing to ensure that the bushing will not shift during processing. During the installation of the mounting base 3, the through hole 8 on the mounting base 3 is aligned with the clamping piece 5 on the worktable 1. The snap-fit ​​groove 6 on the clamping piece 5 can be an arc-shaped structure with its opening facing the side. When the mounting base 3 approaches the clamping piece 5, the clamping piece 5 is inserted into the through hole 8 of the mounting base 3. The locking assembly 7 is provided on the inner wall of the through hole 8, and a limiting groove 9 is opened on its inner side wall. The limiting member 10 can be a sphere, which can move along the length of the limiting groove 9. When the mounting base 3 needs to be installed, the worker pushes the limiting member 10, causing it to move along the limiting groove 9. As the limiting member 10 moves, it gradually snaps into the snap-fit ​​groove 6. Because the spherical structure of the limiting component 10 fits snugly against the arc-shaped structure of the locking groove 6, it restricts the vertical movement of the clamping component 5 after being engaged in the locking groove 6, thus firmly fixing the mounting base 3 onto the worktable 1. At this time, multiple drills 4, positioned on the mounting base 3, are spaced circumferentially around the workpiece clamp 2, ready to perform oil hole machining on the bushing. When it is necessary to replace the drill bit of the drill 4, maintain the drive mechanism inside the mounting base 3, or clean the waste material stuck in the gap, the worker only needs to push the limiting component 10 in the reverse direction to remove it from the locking groove 6. In this way, the mounting base 3 can be easily removed from the worktable 1 for subsequent operations. After the operation is completed, following the above installation steps, the mounting base 3 is reinstalled onto the worktable 1, and the limiting component 10 is pushed into the locking groove 6 to continue machining the oil hole of the bushing.

[0039] For example, such as Figure 2 , Figure 3 As shown, the advantages of this design are: simplified installation and disassembly: the cooperation of clip 5, locking assembly 7, and limiting component 10 eliminates the need for traditional bolt and nut fixing. Installation and disassembly of the mounting base 3 only require moving the limiting component 10 to engage or disengage it from the locking groove 6, making the operation simple and quick, greatly saving installation and disassembly time, improving work efficiency, and solving the problem of cumbersome operation. Facilitating maintenance and component replacement: when it is necessary to replace the drill bit, maintain the drive mechanism, or clean up waste, the mounting base 3 can be quickly removed from the worktable 1, avoiding operational inconvenience caused by space constraints. This makes the maintenance and replacement of internal components of the drilling rig 4 and mounting base 3 easier, reducing equipment downtime and improving equipment utilization.

[0040] like Figures 1-3As shown, a bushing oil hole processing device is illustrated in another embodiment of this disclosure. The locking assembly 7 includes: a hollow housing 11, which is disposed on a mounting base 3 and located within a through hole 8; a vertically movable moving member 12 disposed within the housing 11; a limiting groove 9 located on the moving member 12; the moving member 12 also has a receiving groove 13 communicating with the limiting groove 9; the receiving groove 13 is used to receive a locking member 5; the moving member 12 is arranged such that after moving, it drives the limiting member 10 to engage in the locking groove 6 under the limiting of the inner wall of the housing 11, or after moving, it drives the limiting member 10 to move along the inner wall of the locking groove 6 and retract into the limiting groove 9.

[0041] In some examples, the mounting base 3 is positioned above the worktable 1 via a housing 11. The housing 11 is hollow and fits tightly against the through hole 8 on the mounting base 3, and its shape is similar to a sleeve. The movable component 12 is housed inside the housing 11 and can move smoothly within it, its direction of movement perpendicular to the direction of movement of the limiting component 10. For example, if the limiting component 10 moves horizontally, the movable component 12 moves vertically. When the mounting base 3 needs to be installed, the locking component 5 is first placed at the corresponding position on the worktable 1, with the locking groove 6 of the locking component 5 facing sideways. Then, the mounting base 3 is aligned with the locking component 5 and lowered, allowing the locking component 5 to pass through the through hole 8 of the mounting base 3 and enter the receiving groove 13 of the movable component 12. At this time, the movable component 12 is pushed to move within the housing 11. When the movable component 12 reaches a specific position, the limiting groove 9 aligns with the locking groove 6, and the limiting component 10 engages with the locking groove 6, thereby firmly fixing the mounting base 3 to the worktable 1. At this time, multiple drilling rigs 4 are arranged circumferentially around the workpiece fixture 2, and oil holes can be machined on the bushings placed on the workpiece fixture 2.

[0042] During processing, if maintenance, drill bit replacement, or cleaning of waste material that may be stuck between the mounting base 3 and the worktable 1 is required for drilling rig 4, firstly, move the moving part 12 in the reverse direction to displace the limiting groove 9 from the locking groove 6. Simultaneously, the limiting part 10, driven by the limiting groove 9, disengages from the locking groove 6 and no longer jams the locking part 5. This allows the mounting base 3 to be easily removed from the worktable 1 for subsequent operations. After the operation is completed, repeat the above steps in reverse to reinstall the mounting base 3, and then continue machining the bushing oil hole.

[0043] For example, such as Figure 2 , Figure 3 As shown, the advantage of this design is that it optimizes the installation and disassembly process: by adding the movable part 12 and the outer shell 11, the worker can adjust the position of the limiting part 10 by pushing the movable part 12, avoiding the inconvenience of directly moving the limiting part 10, further simplifying the installation and disassembly operation of the mounting base 3, improving work efficiency, and making equipment maintenance and component replacement more convenient.

[0044] like Figures 1-3As shown, it illustrates a bushing oil hole processing device in another embodiment of the present disclosure. The limiting member 10 is spherical. The limiting groove 9 has a smaller diameter than the diameter of the limiting member 10 at one end near the receiving groove 13, and gradually widens from this end to the other end, with the other end having a diameter greater than or equal to the diameter of the limiting member 10.

[0045] In some examples, firstly, the mounting base 3 is placed on the worktable 1, so that the retaining piece 5 extends into the through hole 8 of the mounting base 3 and falls into the receiving groove 13 of the moving piece 12. At this time, since the size of the limiting groove 9 near the receiving groove 13 is smaller than the diameter of the limiting piece 10, the spherical limiting piece 10 will partially protrude from this end but will not completely pass through this end, thus preventing the limiting piece 10 from accidentally detaching. When the moving piece 12 is pushed close to the retaining piece 5, due to the limited space of the limiting groove 9, the limiting piece 10 will be pushed by the inner wall of the outer shell 11 into the snap-fit ​​groove 6 until the limiting groove 9 and the snap-fit ​​groove 6 are gradually aligned, and the limiting piece 10 is also snapped into the snap-fit ​​groove 6, firmly fixing the mounting base 3 on the worktable 1. The bushing oil hole processing device can then begin drilling the bushing placed on the workpiece fixture 2. Because the limiting groove 9 gradually widens from one end near the receiving groove 13 to the other, it will not jam the limiting member 10. The limiting member 10 can move within the limiting groove 9. When it is necessary to disassemble the mounting base 3, the moving member 12 is moved in the opposite direction. As the moving member 12 moves in the opposite direction, the limiting member 10 will move in the opposite direction along the inner wall of the snap-fit ​​groove 6. The inner wall of the outer shell 11 is also inclined, so that the outer shell 11 does not occupy the internal space of the limiting groove 9. This allows the limiting member 10 to gradually retract into the limiting groove 9 and gradually roll out of the snap-fit ​​groove 6, disengaging from the snap-fit ​​groove 6. At this time, the mounting base 3 can be easily removed from the worktable 1 for maintenance, drill bit replacement, or waste removal operations of the drilling rig 4. After the operation is completed, the mounting base 3 is reinstalled on the worktable 1, and the above steps are repeated to continue machining the bushing oil hole.

[0046] For example, such as Figure 2 , Figure 3As shown, the advantages of this design are: convenient and smooth operation: the use of a spherical limiting component 10 and a limiting groove 9 makes the movement of the limiting component 10 smoother. During installation and disassembly, the limiting component 10 can naturally engage or disengage from the engaging groove 6 by changing the shape of the limiting groove 9, eliminating the need for complex operations and greatly improving the convenience of installing and disassembling the mounting base 3, reducing operation time and increasing work efficiency. Reduced wear and damage: the spherical limiting component 10 rolls within the limiting groove 9, which, compared to other shaped limiting components sliding within the groove, reduces friction between it and the limiting groove 9, thus reducing wear. This not only extends the service life of the limiting component 10 and the limiting groove 9 but also reduces the impact of wear-generated debris on other parts of the equipment, improving the reliability and stability of the entire bushing oil hole processing device. Improved structural compactness: This design eliminates the need for additional complex mechanisms to control the movement and fixation of the limiting component 10. The smooth movement and reliable fixation of the limiting component 10 can be achieved through the ingenious design of the shape of the limiting groove 9, making the structure of the entire locking assembly 7 more compact. It achieves efficient connection and fixation functions within the limited space of the mounting base 3, which is conducive to the miniaturization and integration design of the equipment.

[0047] like Figures 1-3 As shown, it illustrates a bushing oil hole processing device in another embodiment of the present disclosure. The locking assembly 7 further includes: one end of the elastic member 14 acts on the housing 11, and the other end acts on the moving member 12, for providing a force for the moving member 12 to drive the limiting member 10 into the locking groove 6.

[0048] In some examples, when the mounting base 3 approaches the locking piece 5 on the worktable 1, the locking piece 5 extends into the through hole 8 of the mounting base 3 and enters the receiving groove 13 of the moving part 12. At this time, the elastic element 14 begins to function. One end of the elastic element 14 is connected to the inner wall of the outer shell 11, and the other end abuts against the moving part 12. Under the elastic force of the elastic element 14, the moving part 12 is subjected to a force that moves towards the locking piece 5, causing the limiting piece 10 to engage in the locking groove 6, completing the quick fixation of the mounting base 3 and the worktable 1. Then, the drilling rig 4 can be started to process the oil hole of the bushing. When it is necessary to disassemble the mounting base 3, the worker needs to overcome the elastic force of the elastic element 14 and manually move the moving part 12 in the opposite direction. During this process, the elastic element 14 is compressed, the limiting groove 9 and the locking groove 6 are misaligned, the limiting piece 10 disengages from the locking groove 6, and the mounting base 3 can be removed from the worktable 1.

[0049] For example, such as Figure 2 , Figure 3As shown, the advantages of this design are: Automatic locking function: The elastic element 14 gives the locking assembly 7 the characteristic of automatic locking. During the process of the mounting base 3 approaching the locking piece 5, no additional manual operation is required. The elastic element 14 automatically provides the force that causes the moving part 12 to drive the limiting part 10 into the locking groove 6, simplifying the installation process and improving work efficiency. Enhanced connection stability: The continuous force applied by the elastic element 14 ensures that the limiting part 10 always maintains a tight engagement with the locking groove 6. Even during the machining of the bushing oil hole, if the equipment experiences slight displacement due to vibration, the elastic element 14 can promptly adjust the position of the moving part 12 to ensure a stable connection between the limiting part 10 and the locking groove 6, effectively preventing the mounting base 3 from loosening and ensuring machining accuracy. Buffering and protection function: During equipment operation, the elastic element 14 also plays a certain buffering role. When the vibration generated by the drilling rig 4 is transmitted to the connection between the mounting base 3 and the worktable 1, the elastic element 14 can absorb some of the vibration energy, reducing the impact on the locking assembly 7 and other related components, and extending the service life of the equipment. Easy disassembly and control: Although the elastic element 14 provides automatic locking force, the moving element 12 can still be moved in the opposite direction by overcoming the elastic force, thus facilitating the disassembly of the mounting base 3. This design ensures the convenience of automatic locking while also taking into account the controllability of disassembly, meeting the needs of equipment maintenance and component replacement.

[0050] like Figures 1-3 As shown, this invention illustrates a bushing oil hole processing device in another embodiment of the present disclosure. The moving member 12 also has a guide groove 15. The locking assembly 7 further includes: a pressing member 16 movably disposed within the housing 11, located above the moving member 12; a baffle 17 disposed on the inner wall of the housing 11, located on one side of the moving member 12; the pressing member 16, the housing 11, the moving member 12, and the baffle 17 forming a limiting space 18; and a second limiting member 19 located within the limiting space 18. After the pressing member 16 is arranged to move downward, it pushes the second limiting member 19 to squeeze the guide groove 15 and drive the moving member 12 to move upward. The upward movement of the moving member 12 causes the first limiting member 10 to disengage from the snap-fit ​​groove 6.

[0051] In some examples, during the use of the bushing oil hole machining device, when the mounting base 3 is properly connected to the worktable 1 and in the machining state, the components of the locking assembly 7 work together to maintain the stability of the mounting base 3. Suppose that bushing oil hole machining is currently underway, and a drilling rig 4 suddenly malfunctions and requires repair; in this case, the mounting base 3 needs to be disassembled. First, the operator applies downward pressure to the pressing member 16. The pressing member 16 moves downward within the housing 11. Since the pressing member 16, housing 11, moving member 12, and baffle 17 form a limiting space 18, the limiting member 19 within the limiting space 18 is subjected to a downward thrust as the pressing member 16 moves. After being thrust, the limiting member 19 presses against the guide groove 15 on the moving member 12. The guide groove 15 is designed so that the moving member 12 can move in a specific direction when pressed. In this case, under the pressure of the limiting member 19, the moving member 12 moves in the direction that causes the limiting member 10 to disengage from the locking groove 6. As the moving part 12 moves, the limiting groove 9 and the snap-fit ​​groove 6 are misaligned. The limiting part 10, which was originally stuck in the snap-fit ​​groove 6, gradually disengages, thereby separating the mounting base 3 from the worktable 1, facilitating maintenance of the drilling rig 4. After maintenance, the mounting base 3 is reinstalled on the worktable 1. At this time, under the action of the elastic element 14, the moving part 12 automatically moves in the direction that causes the limiting part 10 to snap into the snap-fit ​​groove 6. When the snap-fit ​​5 enters the receiving groove 13 of the moving part 12 and the limiting groove 9 and the snap-fit ​​groove 6 are aligned, the limiting part 10 smoothly snaps into the snap-fit ​​groove 6 as the elastic element 14 pushes the moving part 12, completing the re-fixation of the mounting base 3, and the bushing oil hole processing device can continue processing.

[0052] For example, such as Figure 2 , Figure 3As shown, the advantages of this design are: precise control of disassembly: through the cooperation of the pressing component 16, the second limiting component 19, and the guide groove 15, precise control of the movement of the moving component 12 is achieved, thereby accurately disengaging the first limiting component 10 from the locking groove 6 and completing the disassembly of the mounting base 3. Compared to simply relying on manual direct movement of the moving component 12, this method is more accurate and reliable, reducing the risk of misoperation. Enhanced safety: the setting of the limiting space 18 ensures that the second limiting component 19 moves within a specific space, avoiding safety hazards caused by the arbitrary movement of the second limiting component 19 during the operation of the pressing component 16. At the same time, this structure also ensures that the operation of the pressing component 16 can be stably transmitted to the moving component 12, improving the safety and stability of the entire disassembly process. Improved convenience: when it is necessary to disassemble the mounting base 3, the operator only needs to apply simple pressure to the pressing component 16 to complete the disassembly of the mounting base 3, without the need for complex tools or cumbersome operations. This design greatly improves the convenience of equipment maintenance and component replacement, reduces equipment downtime, and improves production efficiency. Structural stability: The design of baffle 17 and limiting space 18 enhances the overall structural stability of locking assembly 7. During equipment operation, even under vibration or other external forces, the relative positions between moving part 12, pressing part 16 and limiting part 19 remain stable, preventing the mounting base 3 from accidentally loosening due to external forces, thus ensuring the stability and machining accuracy of the bushing oil hole machining device during the machining process.

[0053] like Figures 1-3 As shown, it illustrates a bushing oil hole processing apparatus in another embodiment of the present disclosure, wherein the pressing member 16 has a guide surface 20 that abuts against the limiting member 19.

[0054] In some examples, since the pressing member 16 has a guide surface 20 that abuts against the limiting member 19, when the operator presses the pressing member 16 downwards, the guide surface 20 contacts the limiting member 19. The inclined design of the guide surface 20 allows the pressing member 16 to effectively convert the vertical force into a force that pushes the limiting member 19 to move horizontally during downward movement.

[0055] For example, such as Figure 2 , Figure 3As shown, the advantages of this design are: optimized force transmission: the guide surface 20 optimizes the force transmission between the pressing member 16 and the limiting member 19. It can accurately and efficiently convert the vertical pressure applied by the operator to the pressing member 16 into a force that pushes the limiting member 19 to move horizontally, avoiding force dispersion and loss, making the disassembly operation smoother and less strenuous. Improved operational precision: the guide surface 20 abuts against the limiting member 19, providing precise guidance for the movement of the limiting member 19. This ensures that the limiting member 19 can accurately press against the guide groove 15, thereby precisely controlling the movement of the moving member 12, and thus achieving reliable separation or engagement of the limiting member 10 and the snap-fit ​​groove 6. This high-precision operation helps improve the accuracy of equipment maintenance and installation, and ensures the stable operation of the bushing oil hole processing device.

[0056] like Figures 1-3 As shown, it illustrates a bushing oil hole processing device in another embodiment of the present disclosure. The pressing member 16 has a groove 21, and the moving member 12 has a retaining edge 22. The retaining edge 22 is located in the groove 21 and is used to limit the moving member 12 by locking it on the inner wall of the groove 21.

[0057] In some examples, the engagement of the flange 22 and the groove 21 can limit the amount of movement of the pressing member 16, that is, limit the pressing member 16 to prevent it from accidentally detaching from the housing 11, thereby enhancing the stability of the pressing member 16.

[0058] like Figures 1-3 As shown, it illustrates a bushing oil hole processing apparatus in another embodiment of the present disclosure, with the top of the pressing member 16 extending outside the housing 11.

[0059] In some examples, since the top of the pressing element 16 extends outside the housing 11, the operator does not need any tools or to reach inside the housing 11 to find the operating point. He can simply stand next to the bushing oil hole processing device and easily touch the top of the pressing element 16 with his hand.

[0060] For example, such as Figure 2 , Figure 3 As shown, the advantages of this design are significantly improved ease of operation: the top of the pressing component 16 extends beyond the outer casing 11, greatly facilitating the operator's handling of the pressing component 16. No additional tools or complex actions are required; it can be operated simply by reaching out, significantly reducing the time required to disassemble the mounting base 3, improving equipment maintenance efficiency, reducing equipment downtime, and ensuring production continuity.

[0061] like Figures 1-3 As shown, it illustrates a bushing oil hole processing device in another embodiment of the present disclosure, wherein the limiting member 2 19 is spherical.

[0062] For example, such as Figure 2 , Figure 3 As shown, the advantages of this design are: efficient force transmission: when the spherical limiting member 19 contacts the guide surface 20 of the pressing member 16, rolling friction replaces sliding friction, greatly reducing friction and making force transmission more efficient. This means that it is easier for the operator to press the pressing member 16; only a smaller force is needed to push the limiting member 19 to squeeze the guide groove 15, thereby moving the moving member 12 and completing the disassembly of the mounting base 3, improving operational efficiency. Reduced component wear: Compared to sliding friction, rolling friction causes less wear on the guide surface 20 and the guide groove 15. During long-term use, the spherical limiting member 19 can effectively reduce the degree of wear with surrounding components, extend the service life of the pressing member 16, the moving member 12, and other related components, reduce equipment failures caused by component wear, and lower equipment maintenance costs.

[0063] like Figures 1-3 As shown, a bushing oil hole processing device is shown in another embodiment of the present disclosure, wherein two limiters 19, baffle 17 and limiters 10 are symmetrically distributed along the moving member 12.

[0064] For example, such as Figure 2 , Figure 3 As shown, the advantages of this design are enhanced operational stability: the symmetrically distributed limiting component 2 19, baffle 17, and limiting component 10 ensure that the moving component 12 experiences uniform force on both sides during its movement, preventing tilting or jamming of the moving component 12 due to uneven force distribution. This guarantees the stability and smoothness of the disassembly and installation process of the mounting base 3, reduces operational difficulty, and increases the success rate of operation. Optimized force transmission and distribution: the symmetrical structure optimizes the force transmission path and distribution method. The force applied by the pressing component 16 is evenly transmitted to the moving component 12 through the limiting components 2 19 on both sides, enabling the moving component 12 to move more precisely according to design requirements. This, in turn, accurately controls the movement of the limiting component 10, improving the working efficiency and reliability of the entire locking assembly 7.

Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
