Description

Technical Field

[0001] This application belongs to the field of drive axle processing technology, specifically relating to a lifting processing table for drive axle processing. Background Technology

[0002] The drive axle is the core component of a loader's transmission system. It is responsible for transmitting the torque output from the engine to the drive wheels via the drive shaft, thereby driving the loader forward or backward. Mechanisms within the drive axle, such as the final drive and differential, can change the direction and magnitude of the torque to adapt to different working conditions.

[0003] During the production and processing of the drive axle, each part needs to be processed independently before assembly.

[0004] Currently, when drilling the drive axle housing, the positioning fixture trolley must first be moved out of the drill jig, and then the drive axle housing is hoisted onto the positioning fixture trolley by a crane. Next, the positioning fixture trolley is moved under the drill jig, and then the positioning fixture trolley is driven to rise, raising the height of the drive axle housing so that it is fixed under the action of the drill jig. Then, the drilling operation is performed. After drilling is completed, the drive axle housing is removed with auxiliary tools, and then the above operation is repeated. The entire processing steps are cumbersome and time-consuming, resulting in low processing efficiency of the drive axle housing. Therefore, a lifting processing table for drive axle processing is proposed. Utility Model Content

[0032] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0033] See also Figures 1 to 3 As shown in the embodiment of this application, a lifting processing table for processing drive axles is provided, including a base 1, a scissor-type hydraulic lifting assembly, a movable table 9, a dual-station placement table, two support frames 2, and an XYZ moving platform 8.

[0034] The scissor-type hydraulic lifting assembly is mounted on the base 1.

[0035] The movable platform 9 is located on top of the scissor lift assembly, so that the scissor lift assembly can drive the movable platform 9 to rise and fall.

[0036] The dual-station placement platform is horizontally slidably set on the movable platform 9, and the dual-station placement platform is provided with a drive axle housing positioning seat 5.

[0037] Two support frames 2 are located on opposite sides of the scissor-type hydraulic lifting assembly. Each support frame 2 is equipped with a clamping assembly, which can move towards each other to clamp the drive axle on the drive axle housing positioning seat 5.

[0038] The XYZ mobile platform 8 is located on top of the support frame 2, and a punching machine 7 is installed on the XYZ mobile platform 8.

[0039] The lifting machining table for drive axle processing in this embodiment simplifies the entire process of loading, positioning, processing, and unloading the drive axle housing by incorporating a dual-station sliding, hydraulic lifting, and automatic clamping structure. This reduces manual intervention steps, lowers the labor intensity of operators, and minimizes processing risks caused by improper manual operation, thereby improving the overall safety and convenience of the processing. The lifting machining table in this embodiment eliminates the need for frequent movement of the positioning fixture trolley in and out of the drilling jig and avoids repeated hoisting of the drive axle housing using a crane, thus improving the processing efficiency of the drive axle housing and consequently, the overall processing efficiency of the drive axle.

[0040] By setting up a horizontally sliding dual-station placement platform, while the drive axle is fixed at one station by clamping components and the drilling machine 7 is driven by the XYZ moving platform 8 to perform drilling operations, the loading and unloading of the drive axle housing is completed at the other station simultaneously. There is no need to wait for the current station to finish processing before preparing for the next workpiece, which greatly shortens the process interval time.

[0041] By enabling the scissor-type hydraulic lifting assembly to stably lift the movable table 9 and the dual-station placement table, the height of the drive axle housing can be adjusted according to its dimensions and the processing height requirements of the drilling machine 7, ensuring precise alignment between the drive axle housing, clamping assembly, and drilling machine 7. Simultaneously, the XYZ moving platform 8 allows the drilling machine 7 to move flexibly in three-dimensional space, adapting to different drilling requirements for different positions and specifications of the drive axle housing. This eliminates the need for frequent equipment changes or adjustments to the overall device structure, improving the equipment's adaptability to various processing scenarios.

[0042] By allowing the clamping components on the two support frames 2 to move towards each other, the drive axle housing on the positioning seat of the dual-station placement table is stably clamped, preventing displacement and shaking of the drive axle housing during drilling and ensuring accurate drilling position. The scissor-type hydraulic lifting assembly provides stable support for the movable table 9, reducing shaking during lifting and further ensuring the positional stability of the drive axle housing during height adjustment and processing.

[0043] Among them, the XYZ mobile platform 8 is the XYZ high-precision mobile platform.

[0044] The top of the movable platform 9 is equipped with a first hydraulic cylinder 10, and the movable end of the first hydraulic cylinder 10 is connected to the dual-station placement platform.

[0045] By installing a first hydraulic cylinder 10 on the top of the movable table 9, with its movable end connected to the dual-station placement table, a stable and controllable power source can be provided for the horizontal sliding of the dual-station placement table. The first hydraulic cylinder 10 has strong driving force and runs smoothly, and can accurately control the sliding speed and displacement of the dual-station placement table, ensuring that the dual-station placement table can accurately move to the processing station or loading / unloading station, avoiding the inability of the drive axle housing to accurately align the clamping components or the drilling machine 7 due to insufficient power or displacement deviation. At the same time, with the automatic drive of the first hydraulic cylinder 10, there is no need for manual adjustment of the position of the dual-station placement table, further reducing manual operation steps, improving the efficiency and accuracy of dual-station switching, ensuring smooth connection of subsequent clamping, drilling and other processes, and helping to improve the overall processing efficiency.

[0046] The dual-station placement platform includes two workstations 6, and each of the two workstations 6 is detachably connected to a drive axle housing positioning seat 5.

[0047] By setting the dual-station placement stage as two independent workstations 6, and each workstation 6 being detachably connected to the drive axle housing positioning seat 5, the appropriate positioning seat can be quickly replaced according to the processing requirements of different specifications of drive axle housings, without having to replace the entire placement stage. This greatly improves the equipment's compatibility with different types of workpieces and reduces equipment replacement costs.

[0048] At least two crossbars 12 are provided between the bottoms of the two workstations 6. The bottom of each crossbar 12 is fixedly connected to a slider 13, and the slider 13 is slidably connected to the slide rail 14 on the movable table 9. The movable end of the first hydraulic cylinder 10 is fixedly connected to one of the sliders 13.

[0049] The two workstations 6 are connected by a crossbar 12 and slide along the slide rail 14 of the movable table 9 via a slider 13. This ensures that the dual-workstation platform slides stably along the slide rail 14 under the drive of the first hydraulic cylinder 10, preventing deviation or jamming during sliding and ensuring smooth and accurate workstation switching. Simultaneously, the crossbar 12 enhances the structural connection strength between the two workstations 6, guaranteeing overall stability. The slider 13, in cooperation with the slide rail 14, further reduces the frictional resistance during sliding of the dual-workstation platform, extending component lifespan and ensuring smooth and reliable workstation switching during long-term use, providing structural support for efficient parallel processing of two workstations.

[0050] There are two horizontal bars 12, which are arranged in parallel, and the sliders 13 are arranged in a one-to-one correspondence with the horizontal bars 12.

[0051] Two workstations 6 are arranged along the extension and retraction direction of the first hydraulic cylinder 10. The slide rail 14 and the slider 13 are set in a one-to-one correspondence. The slide rail 14 is set on the top surface of the movable table 9. The crossbar 12 and the slide rail 14 both extend along the extension and retraction direction of the first hydraulic cylinder 10.

[0052] By arranging the two workstations 6 along the extension and retraction direction of the first hydraulic cylinder 10, and ensuring that the slide rail 14 corresponds one-to-one with the slider 13, and that the crossbar 12 and slide rail 14 both extend along this extension and retraction direction, on the one hand, the driving force of the first hydraulic cylinder 10 can be directly transmitted along the arrangement direction of the workstations 6, avoiding directional deviation during power transmission. This ensures that the dual-workstation placement platform always moves along a fixed path during sliding, accurately realizing the switching between the workstation to be processed and the processing workstation, and preventing the drive axle housing from failing to accurately align with the clamping components and the drilling machine 7 due to deviation in the sliding direction. On the other hand, the one-to-one correspondence between the slide rail 14 and the slider 13, as well as the unidirectional extension of the crossbar 12 and the slide rail 14, makes the force on the dual-workstation placement platform more uniform, the sliding process more stable, and reduces shaking or jamming during sliding. At the same time, it enhances the overall structural stability of the dual-workstation placement platform, preventing component damage due to uneven force during long-term use, ensuring the efficiency of workstation switching and the service life of the equipment, further supporting the stable operation of the dual-workstation parallel processing mode, and helping to improve the processing efficiency of the drive axle housing.

[0053] The scissor lift assembly includes a first lifting section and a second lifting section. The middle sections of the first lifting section and the second lifting section are hinged together. A base 15 is provided on the top of the base 1. The bottom end of the first lifting section is rotatably connected to the base 15. The bottom end of the second lifting section is slidably connected to the base 15 along a first direction. The bottom ends of the first and second lifting sections are arranged opposite to each other along the first direction. The top end of the first lifting section is slidably connected to the movable platform 9 along the first direction. The top end of the second lifting section is rotatably connected to the movable platform 9. The top ends of the first and second lifting sections are arranged opposite to each other along the first direction.

[0054] By hinged to the middle of the first lifting part and the middle of the second lifting part, and with the bottom and top ends of the first and second lifting parts respectively connected to the base 15 and the movable table 9 by rotational and sliding connections, the movable table 9 can be stably adjusted in height by the relative rotation and sliding of the first and second lifting parts. The lifting process is smoother and can effectively prevent the movable table 9 from tilting or shaking during lifting. This ensures that the drive bridge housing placed on the dual-station placement table always remains horizontal, ensuring the accuracy of subsequent clamping assembly alignment and clamping and the processing of the drilling machine 7.

[0055] By aligning the bottom ends of the first and second lifting parts with each other along the first direction, and aligning the top ends of the first and second lifting parts with each other along the first direction, the lifting components can be subjected to more balanced forces during lifting, extending their service life. Furthermore, the sliding connection design makes lifting adjustment more flexible, allowing for precise control of the lifting height of the movable table 9 according to the processing height requirements of the drive axle housing. This further adapts to the processing requirements of drive axle housings of different specifications, providing a stable height adjustment guarantee for the smooth operation of the overall processing flow.

[0056] The first lifting unit includes two first connecting rods 16 arranged along a second direction. The second lifting unit includes two second connecting rods 18 arranged along the second direction. The first connecting rods 16 and 18 are arranged one-to-one along a first direction, and the middle part of the first connecting rod 16 is hinged to the middle part of the corresponding second connecting rod 18. The first and second directions are horizontal and vertical. The bottom ends of the two first connecting rods 16 are connected by a first round rod 41 and are rotatably connected to the base 15 via the first round rod 41. The bottom ends of the two second connecting rods 18 are connected by a second round rod 42 and are slidably connected to the slide groove 11 of the base 15 along the first direction via the second round rod 42. The top ends of the two first connecting rods 16 are connected by a third round rod 43 and are slidably connected to the slide groove 11 of the movable platform 9 along the first direction via the third round rod 43. The top ends of the two second connecting rods 18 are connected by a fourth round rod 44, and are rotatably connected to the movable platform 9 through the fourth round rod 44.

[0057] The first lifting part is configured as two first connecting rods 16 arranged along the second direction, and the second lifting part is configured as two second connecting rods 18 arranged along the second direction. The corresponding connecting rods are connected by a first round rod 41, a second round rod 42, a third round rod 43, and a fourth round rod 44, respectively. The base 15 and the sliding groove 11 of the movable platform 9 are used to achieve sliding and rotational connection. At the same time, a second hydraulic cylinder 17 is set between the mounting sleeves 3 of the first round rod 41 and the second round rod 42, which can form symmetrical support for the movable platform 9 from the second direction. This greatly improves the overall load-bearing capacity and stability of the scissor-type hydraulic lifting assembly, avoids the movable platform 9 from tilting due to uneven force on one side, and ensures that the drive axle housing remains horizontal during the lifting process, providing positional guarantee for subsequent precise clamping and drilling.

[0058] Both the movable platform 9 and the base 15 are roughly rectangular in shape. The two first connecting rods 16 and the two second connecting rods 18 are roughly connected at the bottom four corners of the movable platform 9 and the top four corners of the base 15.

[0059] A mounting sleeve 3 is fitted onto both the first round rod 41 and the second round rod 42, and a second hydraulic cylinder 17 is provided between the two mounting sleeves 3.

[0060] The second hydraulic cylinder 17 acts directly on the first round rod 41 and the second round rod 42 located at the bottom through the mounting sleeve 3, which can drive the first and second lifting parts to expand or contract synchronously and smoothly. With the limiting and guiding of the round rods by the slide groove 11, the lifting speed and height adjustment of the movable table 9 can be more precise and controllable, adapting to the height requirements of different specifications of drive axle housings. In addition, this modular connecting rod and round rod connection structure not only facilitates the installation and maintenance of components, but also disperses the stress during the lifting process, reduces the wear of individual components, extends the overall service life of the equipment, and further ensures the continuity and efficiency of the drive axle processing.

[0061] Among them, the first round rod 41, the second round rod 42, the third round rod 43 and the fourth round rod 44 are all horizontally arranged and parallel to each other.

[0062] The hydraulic lifting assembly has a roughly rectangular parallelepiped shape, with the first direction being the length of the scissor lift assembly and the second direction being the width of the scissor lift assembly. Alternatively, the first direction may be the width of the scissor lift assembly, and the second direction may be the length of the scissor lift assembly.

[0063] Both clamping assemblies include a third hydraulic cylinder 21, which is fixedly embedded in the corresponding support frame 2. The movable end of the third hydraulic cylinder 21 passes through the corresponding support frame 2 and is fixedly connected to a mounting plate 19. A positioning clamp 20 is detachably connected to the mounting plate 19.

[0064] By setting a third hydraulic cylinder 21, with its movable end passing through the corresponding support frame 2 and fixedly connected to a mounting plate 19, and a positioning clamp 20 detachably connected to the mounting plate 19, the system achieves several advantages. Firstly, the third hydraulic cylinder 21 provides a stable and controllable driving force, propelling the mounting plate 19 and the positioning clamp 20 to move precisely in opposite directions. Secondly, the detachable connection between the positioning clamp 20 and the mounting plate 19 allows for the replacement of the entire clamping assembly with a suitable positioning clamp 20 when different specifications of drive axle housings need to be processed. This reduces equipment adjustment costs and enhances the flexibility to adapt to different processing requirements.

[0065] The support frame 2 is roughly flat, and the third oil cylinder 21 is vertically fixed and embedded in the support frame 2, which can enhance the stability of the oil cylinder installation.

[0066] Each mounting plate 19 is provided with two parallel guide rods 22, which are slidably connected to the corresponding support frame 2 to ensure the stable movement of the mounting plate 19.

[0067] Among them, the two guide rods 22 are located on both sides of the piston of the third oil cylinder 21.

[0068] The mounting plate 19 and the positioning clamp 20 are fixedly connected by multiple bolts, which facilitates the assembly and disassembly of the mounting plate 19 and the positioning clamp 20.

[0069] The XYZ moving platform 8 is located at the top of one support frame 2 and at the top of another support frame 2. The XYZ moving platform 8 includes a Z-axis slider 13 and a punching machine 7 is mounted on the Z-axis slider 13.

[0070] By setting both ends of the XYZ mobile platform 8 on the top of the two support frames 2 respectively, a straddle support structure is formed, which can provide a more stable installation foundation for the XYZ mobile platform 8, effectively distribute the weight of the platform itself and the drilling machine 7, reduce the shaking or displacement of the platform due to uneven force during movement, and ensure the positional accuracy of the drilling machine 7 in three-dimensional movement.

[0071] By mounting the drilling machine 7 on the Z-axis slider 13 of the XYZ moving platform 8, the vertical processing height of the drilling machine 7 can be precisely adjusted by the precise lifting and lowering of the Z-axis slider 13. Combined with the movement in the X and Y axes, the drilling machine 7 can be quickly and accurately positioned at the processing position on the drive axle housing without the need for an additional lifting mechanism for the drilling machine 7, simplifying the overall structure of the equipment. It also ensures that the drilling machine 7 is always located directly above the dual-station placement table, precisely aligned with the drive axle housing after the clamping assembly is positioned, avoiding processing misalignment due to installation position deviation, and further improving the accuracy and efficiency of drilling the drive axle housing. At the same time, the straddle support structure also provides sufficient space for the horizontal sliding of the dual-station placement table, ensuring that station switching and drilling operations do not interfere with each other, and guaranteeing the smoothness of the overall processing flow.

[0072] It should be noted that, in actual use, an existing PLC controller and hydraulic pump station can be added. The pump station is connected to the existing pipelines and control valves of each cylinder. The PLC controller is electrically connected to the pump station, the XYZ high-precision moving platform, and the drilling machine 7 to facilitate overall control. The specific data analysis and processing involved to further realize the control function are methods that can be implemented by those skilled in the art based on common knowledge. These methods are not within the scope of this solution. The above description is only to illustrate the beneficial effects that can be achieved by this hardware structure improvement in conjunction with common knowledge.

[0073] Example:

[0074] This embodiment provides a lifting processing table for drive axle machining, including a base 1. A base 15 is fixedly connected to the top of the base 1. A scissor-type hydraulic lifting assembly is installed on the top of the base 15. A movable platform 9 is fixedly connected to the top of the scissor-type hydraulic lifting assembly. A first hydraulic cylinder 10 is fixedly installed on one side of the top of the movable platform 9. A dual-station placement table is fixedly connected to the movable end of the first hydraulic cylinder 10. Two drive axle housing positioning seats 5 are symmetrically fixedly installed on the top of the dual-station placement table. The dual-station placement table includes two workstations 6. The two drive axle housing positioning seats 5 are connected to the adjacent workstations 6. The drive axle housing is fixedly connected by multiple bolts, and the drive axle housing positioning seat 5 is detachably fixedly installed on the top of the adjacent workstation 6. The bottom of the two workstations 6 are fixedly connected to two crossbars 12. The bottom of each crossbar 12 is fixedly connected to a slider 13. One slider 13 is fixedly connected to the movable end of the first oil cylinder 10. The bottom of the other single slider 13 is slidably connected to a slide rail 14. The slide rail 14 is fixedly installed on the top of the movable table 9, which can realize the workstation switching operation, move the drive axle housing to be processed to the processing workstation, and move the processed drive axle housing to the loading and unloading workstation.

[0075] A base 15 is provided on the top of the base 1. The scissor-type hydraulic lifting assembly includes a first lifting part and a second lifting part. The first lifting part includes two first connecting rods 16, which are arranged along a second direction. The second lifting part includes two second connecting rods 18, which are also arranged along a second direction. The first connecting rods 16 and 18 are arranged one-to-one in a first direction, and the middle part of the first connecting rod 16 is hinged to the middle part of the corresponding second connecting rod 18. The first and second directions are horizontal and vertical. The bottom ends of the two first connecting rods 16 are connected by a first round rod 41 and are rotatably connected to the base 15 through the first round rod 41. The bottom ends of the two second connecting rods 18 are connected by a second round rod 42 and are slidably connected to the slide groove 11 of the base 15 along the first direction through the second round rod 42. The top ends of the two first connecting rods 16 are connected by a third round rod 43 and are slidably connected to the slide groove 11 of the movable table 9 along the first direction through the third round rod 43. The top ends of the two second connecting rods 18 are connected by a fourth round rod 44, and are rotatably connected to the movable table 9 via the fourth round rod 44. Mounting sleeves 3 are fitted onto both the first round rod 41 and the second round rod 42, and a second hydraulic cylinder 17 is positioned between the two mounting sleeves 3.

[0076] The bottom ends of the two first connecting rods 16 are fixedly connected by a first round rod 41, and the first round rod 41 is rotatably connected to the base 15 on the base 1, meaning that the first round rod 41 can rotate around its own axis, causing the two first connecting rods 16 to rotate synchronously with their bottom ends as fulcrums. The top ends of the two first connecting rods 16 are fixedly connected by a third round rod 43, and the third round rod 43 is slidably connected to the slide groove 11 at the bottom of the movable platform 9, meaning that the third round rod 43 can slide along the extension direction of the slide groove 11, that is, along the first direction, while simultaneously causing the top ends of the two first connecting rods 16 to slide synchronously. The bottom ends of the two second connecting rods 18 are fixedly connected by a second round rod 42, and the second round rod 42 is slidably connected to the slide groove 11 at the top of the base 15, meaning that the second round rod 42 can slide along the extension direction of the slide groove 11, that is, along the first direction, while simultaneously causing the bottom ends of the two second connecting rods 18 to slide synchronously. The top ends of the two second connecting rods 18 are fixedly connected by the fourth round rod 44. The fourth round rod 44 is rotatably connected to the bottom of the movable platform 9, that is, the fourth round rod 44 can rotate around its own axis, driving the top ends of the two second connecting rods 18 to rotate synchronously with the top end as the fulcrum.

[0077] A mounting sleeve 3 is fitted onto the outer surface of the first round rod 41, and a mounting sleeve 3 is also fitted onto the outer surface of the second round rod 42. The two mounting sleeves 3 are respectively connected to the corresponding first round rod 41 and second round rod 42. The two ends of the second hydraulic cylinder 17 are rigidly connected to the two mounting sleeves 3, so that the extension and retraction of the second hydraulic cylinder 17 can directly drive the two mounting sleeves 3 to move closer or further apart relative to each other in the first direction.

[0078] A support frame 2 is fixedly connected to the top of the base 1. Clamping components are symmetrically fixedly installed on both sides of the support frame 2. Each of the two drive axle housing clamping components includes a third hydraulic cylinder 21, and the third hydraulic cylinder 21 is fixedly embedded in one side of the outer surface of the support frame 2. The movable end of the third hydraulic cylinder 21 passes through the support frame 2 and is fixedly connected to a mounting plate 19. A positioning clamp 20 is detachably fixedly installed on one side of the outer surface of the mounting plate 19. The mounting plate 19 and the positioning clamp 20 are fixedly connected by multiple bolts. Two guide rods 22 are symmetrically fixedly connected to one side of the outer surface of the mounting plate 19. The guide rods 22 pass through the support frame 2 and are slidably connected to it, which can position and clamp the drive axle housing.

[0079] The top of the support frame 2 is fixedly mounted with an XYZ high-precision moving platform. The XYZ high-precision moving platform mainly includes an X-axis moving part, a Y-axis moving part, and a Z-axis moving part. The couplings of each axis are connected to servo motors to achieve automatic adjustment. A drilling machine 7 is fixedly mounted on the Z-axis slider 13 of the XYZ high-precision moving platform. The drilling machine 7 consists of a housing, a drilling motor, a drill chuck, and a drill bit. The housing is fixed to the Z-axis slider 13, the drilling motor is fixedly installed inside the housing, the drill chuck is fixedly installed on the drive end of the drilling motor, and the drill bit is fixedly installed on the drill chuck.

[0080] Working principle: The drive axle housing to be processed is placed on the drive axle housing positioning seat 5. Then, the second hydraulic cylinder 17 pushes the two mounting sleeves 3 to separate, thereby pushing the first round rod 41 and the second round rod 42 at the bottom to separate from each other. Through the first connecting rod 16, the second connecting rod 18 and the slide 11, the movable table 9 is driven to descend. The movable table 9, through the first hydraulic cylinder 10, the slider 13, the crossbar 12, etc., drives the two workstations 6 and the drive axle housing positioning seat 5 to descend, reducing the height of the drive axle housing. Then, the first hydraulic cylinder 10 operates, pulling the slider 13 connected to it. The first hydraulic cylinder 10 moves to one side, thereby moving the worktable 6 and the drive axle housing positioning seat 5 through the crossbar 12, moving the drive axle housing to be processed to the middle position. Then, the drive axle housing is raised by the scissor-type hydraulic lifting assembly and other components, so that it is positioned between the two positioning clamps 20. The two third hydraulic cylinders 21 operate, and the third hydraulic cylinders 21 push the mounting plate 19 closer to the drive axle housing, thereby moving the positioning clamps 20 closer to the drive axle housing until the positioning and clamping operation is completed. Then, the XYZ high-precision moving platform and the drilling machine 7 operate to perform the drilling operation.
