Description

Technical Field

[0001] This invention relates to the field of automatic processing technology for support frames, specifically a fully automatic processing device for air suspension support frames. Background Technology

[0002] As a core load-bearing component of the air suspension system, the air suspension support frame's machining precision and production efficiency directly affect the suspension assembly quality and overall vehicle driving stability. It is widely used in air suspension systems of various vehicles, including passenger cars and commercial vehicles. With the intelligent and automated development of the automotive industry, the market has placed higher demands on the machining technology of air suspension support frames. Related processing equipment is upgrading towards full automation, multi-station operation, and integration. Various loading, positioning, processing, and unloading devices for support frame machining are constantly emerging, aiming to achieve efficient connection of the processing flow through optimized mechanical structure design.

[0003] Current processing devices for air suspension support frames still have many shortcomings. Traditional processing equipment is mostly a single-station operation mode, requiring manual assistance for loading and unloading, which not only consumes labor costs but is also prone to affecting processing positioning accuracy due to human error. At the same time, the clamping and fixing of the support frame mostly adopts traditional connection methods, which are cumbersome to assemble and disassemble and have poor adaptability, making it difficult to quickly change different specifications of load-bearing components. The processing position adjustment also lacks flexible linkage mechanisms, resulting in limited processing adaptability and operating efficiency. In addition, the processing, inspection, and chip removal processes of some processing devices are independent and have not achieved integrated operation. The large gaps between processes further reduce the overall processing efficiency and cannot meet the needs of large-scale, high-precision production. Summary of the Invention

[0019] The following description is intended to disclose the invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will occur to those skilled in the art.

[0020] Example 1

[0021] Please refer to Figures 1 to 13 As shown, an automatic processing device for an air suspension support frame includes a processing table 1. Two belt conveyors 101, spaced apart front to back, are fixedly connected to the left half of the top of the processing table 1. The two belt conveyors 101 convey in opposite directions. A first upright 102 is fixedly connected to the center of the top of the processing table 1. A three-station material handling mechanism 2 is provided on the first upright 102. A rotary disk 103 is connected to the right half of the top of the processing table 1 via a reciprocating rotation mechanism 3. Two symmetrically arranged rotating bases 104 are rotatably connected to the top of the rotary disk 103. A material loading mechanism 5 is connected to the top of the rotating bases 104 via a quick-release connection mechanism 4. A support frame body 105 is provided inside the material loading mechanism 5. A processing position adjustment mechanism 6 connected to the two rotating bases 104 is also provided on the top of the rotary disk 103. A three-station processing mechanism 7 is provided at the right edge of the top of the processing table 1. A processing fixing mechanism 8 is also provided at the rear edge of the top of the processing table 1.

[0022] Those skilled in the art will understand that the left half of the processing table 1 is equipped with two belt conveyors 101 with opposite conveying directions to realize material transmission for loading and unloading. The first upright frame 102 at the top center is equipped with a three-station material handling mechanism 2 to complete material clamping and transfer. The right half is connected to the rotary disk 103 through a reciprocating rotation mechanism 3. The two rotating bases 104 on the rotary disk 103 are equipped with a matching material loading mechanism 5 through a quick-release connection mechanism 4. The support frame body 105 is placed in the material loading mechanism 5. The processing position adjustment mechanism 6 can adjust the processing angle of the support frame body 105. The three-station processing mechanism 7 completes multi-process processing. The processing fixing mechanism 8 realizes stable pressing during processing. This main structure integrates the loading, positioning, adjustment, processing, fixing and unloading mechanisms into the processing table 1 to realize seamless connection of each process and lay the structural foundation for the fully automatic operation of the device. At the same time, the design of the double rotating base 104 provides conditions for alternating operation and greatly improves the continuity of equipment operation.

[0023] Example 2

[0024] Furthermore, the three-station material handling mechanism 2 includes a first motor 201 fixedly connected inside the first upright 102. The output end of the first motor 201 is fixedly connected to a first three-station rotating frame 202 located above the first upright 102. Vertically arranged first hydraulic rods 203 are fixedly connected to the three plates of the first three-station rotating frame 202. A first mounting frame 205 is fixedly connected to the bottom output end of the first hydraulic rod 203. A first guide rod 204 is fixedly connected to the top of the first mounting frame 205. The first guide rod 204 is slidably connected to the first three-station rotating frame 202. A second motor 206 is fixedly connected inside the first mounting frame 205. A pneumatic gripper 207 located below the first mounting frame 205 is fixedly connected to the output end of the second motor 206. The three pneumatic grippers 207 correspond to the two belt conveyors 101 and the left rotating base 104, respectively.

[0025] Those skilled in the art will understand that the first motor 201 drives the first three-station rotating frame 202 to rotate 120° each time. The first hydraulic rod 203 on the first three-station rotating frame 202 drives the first mounting frame 205 to move up and down. The first guide rod 204 provides sliding guidance for the first mounting frame 205 to ensure movement stability. The second motor 206 drives the pneumatic grippers 207 to clamp and release the support frame body 105. The three pneumatic grippers 207 correspond to the two belt conveyors 101 and the left rotating base 104, respectively. The first pneumatic gripper 207 clamps the support frame body 105 to be processed from one of the belt conveyors 101. 05. The second pneumatic gripper 207 places the support frame body 105 to be processed on the loading mechanism 5 of the left rotating base 104. The third pneumatic gripper 207 picks up the processed support frame body 105 from the loading mechanism 5 and places it on another belt conveyor 101 to complete the unloading. This mechanism, through the coordinated operation of the three-station 120° intermittent rotation and the pneumatic gripper 207, realizes the automated synchronous operation of loading, transferring and unloading of the workpiece, replacing manual loading and unloading operations. This not only saves labor costs but also avoids positioning errors caused by manual operation, improving the accuracy and efficiency of loading and unloading.

[0026] Example 3

[0027] Furthermore, the reciprocating rotation mechanism 3 includes a first rotating shaft 301 rotatably connected to the top of the processing table 1, a rotating disk 103 fixedly connected to the top of the first rotating shaft 301, the bottom end of the first rotating shaft 301 extending to the bottom of the processing table 1 and fixedly connected to a first gear 302, a slide rail 303 located next to the first gear 302 fixedly connected to the bottom of the processing table 1, a rack 304 meshing with the first gear 302 slidably connected on the slide rail 303, and a second hydraulic rod 305 fixedly connected to the bottom of the processing table 1. The output end of the second hydraulic rod 305 is fixedly connected to one end of the rack 304 through a connecting plate. When the telescopic rod of the second hydraulic rod 305 is fully extended, the first rotating shaft 301 can be rotated 180° through the cooperation of the rack 304 and the first gear 302.

[0028] Those skilled in the art will understand that the extension and retraction of the second hydraulic rod 305 drives the rack 304 to slide on the slide rail 303. The rack 304 meshes with the first gear 302, driving the first rotating shaft 301 to rotate, thereby realizing the rotation of the rotating disk 103. When the extension rod of the second hydraulic rod 305 is fully extended, it can drive the first rotating shaft 301 to rotate 180°. This mechanism realizes the precise 180° reciprocating rotation of the rotating disk 103 through the meshing transmission of the hydraulically driven rack and gear, thereby driving the two rotating bases 104 to interchange positions. This allows the support frame body 105 on the left side, which has completed loading and unloading, to be moved to the processing position on the right side, and the support frame body 105 on the right side, which has completed processing, to be moved to the loading and unloading position on the left side. This realizes the synchronous operation of processing and loading and unloading, effectively reducing the waiting time of the process and improving the overall operating efficiency of the equipment. At the same time, the slide rail 303 provides a sliding guide for the rack 304, ensuring the stability of the meshing transmission and the rotational accuracy.

[0029] Example 4

[0030] Furthermore, the quick-release connection mechanism 4 includes a circular slot 401 opened on the top of the rotating base 104. The bottom of the loading mechanism 5 is fixedly connected to a circular insert 402 that matches the circular slot 401. The bottom of the circular insert 402 has a rectangular guide groove 403. The inner bottom of the circular slot 401 is fixedly connected to a rectangular guide block 404 that matches the rectangular guide groove 403. The interior of the rotating base 104 has a plurality of first sliding cavities 405 arranged in a ring array. Each first sliding cavity 405 is slidably connected to a slider 406. A limiting block 407 is fixedly connected to the side of the slider 406 near the circular insert 402. A first spring 408 is fixedly connected to the side of the slider 406 away from the limiting block 407. The outer circumferential surface of the circular insert 402 has an annular limiting groove 409 that matches each limiting block 407. A force-bearing inclined surface is opened at the top corner of the end of each limiting block 407 near the annular limiting groove 409.

[0031] As will be understood by those skilled in the art, the circular insert 402 is inserted into the circular slot 401 at the top of the rotating base 104, and the rectangular guide block 404 and the rectangular guide groove 403 cooperate to achieve precise positioning and prevent the material loading mechanism 5 from rotating. When the circular insert 402 is inserted, it presses the inclined surface of the limiting block 407, causing the slider 406 to slide in the first sliding cavity 405 and compress the first spring 408. When the circular insert 402 is fully inserted, the first spring 408 resets and pushes the slider 406, causing the limiting block 407 to engage with the annular limiting groove 409, thereby achieving the snap-fit ​​fixation between the material loading mechanism 5 and the rotating base 104. This basic structure achieves rapid installation and initial fixation of the material loading mechanism 5 through the snap-fit ​​method of spring reset. The rectangular guide structure ensures the coaxiality and positioning accuracy of the installation of the material loading mechanism 5, avoiding the offset of the material loading mechanism 5 during processing and affecting the processing accuracy. At the same time, the snap-fit ​​structure has strong stability and can withstand the vibration and force during processing.

[0032] Example 5

[0033] Furthermore, the quick-release connection mechanism 4 also includes a drive rod 410 fixedly connected to the top of the slider 406, a rotating ring 411 rotatably connected to the top of the rotating base 104, and a movable through slot 412 corresponding to each drive rod 410 on the top of the rotating base 104. An arc-shaped drive groove 413 corresponding to each drive rod 410 is opened on the rotating ring 411, and each drive rod 410 is inserted into the corresponding movable through slot 412 and arc-shaped drive groove 413.

[0034] Those skilled in the art will understand that rotating the rotating ring 411 at the top of the rotating base 104 causes the arc-shaped drive groove 413 on the rotating ring 411 to drive the drive rod 410 to move within the movable through groove 412, thereby pulling the slider 406 to slide within the first sliding cavity 405, causing the limiting block 407 to disengage from the annular limiting groove 409, thus unlocking the material loading mechanism 5. This structure converts the rotational motion into the linear sliding of the slider 406 through the arc-shaped drive groove 413 of the rotating ring 411, achieving the synchronous unlocking of multiple limiting blocks 407. The operation is simple and convenient, requiring no additional tools, and greatly improving the disassembly efficiency of the material loading mechanism 5. At the same time, the cooperation between the drive rod 410 and the movable through groove 412 ensures the stability and synchronicity of the slider 406's sliding during the unlocking process.

[0035] Example 6

[0036] Furthermore, the quick-release connection mechanism 4 also includes a handle 414 fixedly connected to the outer peripheral wall of the rotating ring 411. The handle 414 has an installation cavity 415 inside, and a locking rod 416 is horizontally inserted in the installation cavity 415. The outer peripheral wall of the rotating base 104 has a locking groove 417 adapted to the locking rod 416. A retaining ring 418 located inside the installation cavity 415 is fixedly connected to the locking rod 416. A second spring 419 sleeved on the outside of the locking rod 416 is fixedly connected to the side of the retaining ring 418 away from the locking groove 417. The end of the locking rod 416 away from the locking groove 417 extends to the outside of the handle 414 and is fixedly connected to a pull rod 420.

[0037] Those skilled in the art will understand that the handle 414 facilitates the operator to rotate the rotating ring 411. The second spring 419 in the mounting cavity 415 pushes the retaining ring 418, causing the locking rod 416 to engage with the locking groove 417 on the outer peripheral wall of the rotating base 104, thereby fixing the rotating ring 411 and preventing the rotating ring 411 from accidentally rotating during processing, which would cause the limit block 407 to unlock. Pulling the pull rod 420 can drive the locking rod 416 out of the locking groove 417, thereby unlocking the rotating ring 411. This locking structure achieves automatic locking of the rotating ring 411 through the spring-reset locking rod 416, effectively preventing the rotating ring 411 from rotating due to vibration, collision, or other factors during processing, ensuring the reliability of the quick-release connecting mechanism 4. The design of the pull rod 420 makes the unlocking operation simple, taking into account both the stability of the fixation and the convenience of operation, further improving the performance of the quick-release connecting mechanism 4.

[0038] Example 7

[0039] Furthermore, the material loading mechanism 5 includes a placement platform 501 fixedly connected to the top of the circular insert 402. The top of the placement platform 501 is provided with a placement groove 502 that is adapted to the support frame body 105. The support frame body 105 is movably placed in the placement groove 502. Several clearance grooves 503 distributed in a ring array are also provided at the top edge of the placement platform 501. The number of clearance grooves 503 is even.

[0040] Those skilled in the art will understand that the placement platform 501 on the top of the circular insert 402 has a placement groove 502 that matches the support frame body 105, enabling precise placement and initial positioning of the support frame body 105. The even-numbered clearance grooves 503 on the top edge of the placement platform 501 are used by the pneumatic clamping mechanism 2 of the three-station material handling mechanism 2 to clamp the support frame body 105 through clearance space. The mechanism ensures the positioning accuracy of the support frame body 105 through the placement groove 502 that matches the support frame body 105, laying the foundation for subsequent processing accuracy. At the same time, the material loading mechanism 5 is connected to the rotating base 104 through the quick-release connection mechanism 4, which allows for quick replacement of the appropriate material loading mechanism 5 according to different specifications of the support frame body 105, improving the processing adaptability of the equipment.

[0041] Example 8

[0042] Furthermore, the processing position adjustment mechanism 6 includes a cavity 601 opened inside the rotary disk 103. A second rotating shaft 602 is rotatably connected to the center of the top of the cavity 601. The top end of the second rotating shaft 602 extends to the top of the rotary disk 103 and is fixedly connected to a second gear 603. The outer peripheral walls of the two rotating bases 104 are fixedly connected to external gear rings 604 that mesh with the second gear 603. A worm gear 605 is fixedly connected to the bottom end of the second rotating shaft 602. Two symmetrically distributed fixed plates 606 are also fixedly connected to the top of the cavity 601. A worm 607 that meshes with the worm gear 605 is rotatably connected between the two fixed plates 606. A third motor 608 is fixedly connected to the outer side of one of the fixed plates 606. The output end of the third motor 608 is fixedly connected to one end of the worm 607.

[0043] As will be understood by those skilled in the art, the third motor 608 drives the worm 607 to rotate, and the worm 607 meshes with the worm wheel 605 to drive the second rotating shaft 602 to rotate, thereby causing the second gear 603 to rotate. The second gear 603 meshes with the external gear ring 604 on the outer peripheral wall of the two rotating bases 104, causing the two rotating bases 104 to rotate around their own axes, thereby realizing the circumferential angle adjustment of the material loading mechanism 5 and the support frame body 105. Moreover, the worm 607 and the worm wheel 605 have a self-locking structure, and automatic positioning can be achieved after adjustment. This mechanism uses the reduction transmission of the worm and worm wheel and the external gear ring to achieve the circumferential angle adjustment of the material loading mechanism 5 and the support frame body 105. The meshing transmission enables precise and stable adjustment of the circumferential machining position of the support frame body 105, and can drive the placement table 501 to rotate at any angle, facilitating the three-station machining mechanism 7 to process different positions on the top of the support frame body 105 without removing the machining fixing mechanism 8, or removing the support frame body 105 from the placement slot 502, adjusting the angle, and re-inserting and fixing it. This significantly saves the time for angle adjustment and improves machining efficiency. At the same time, the self-locking characteristics of the worm gear and worm wheel ensure the stability of the position of the support frame body 105 after adjustment, avoiding angle deviation during machining that affects machining accuracy.

[0045] Furthermore, the three-station machining mechanism 7 includes a second upright 701 fixedly connected to the right edge of the top of the machining table 1. A mounting groove 702 is provided on the left side of the second upright 701. A vertically arranged lead screw 703 is rotatably connected inside the mounting groove 702. A fourth motor 704 is fixedly connected to the top of the second upright 701. The output end of the fourth motor 704 is fixedly connected to the top end of the lead screw 703. A second guide rod 705 parallel to the lead screw 703 is also fixedly connected inside the mounting groove 702. A lifting frame 706 is threaded onto the lead screw 703. Simultaneously, it is slidably connected to the second guide rod 705. The top of the lifting frame 706 is fixedly connected to the fifth motor 707. The output end of the fifth motor 707 is fixedly connected to the second and third station rotating frame 708. The bottom of the three plates of the second and third station rotating frame 708 is respectively equipped with a thread drill bit 709, a groove depth sensor 710 and a high-pressure jet nozzle 711. The top of the second and third station rotating frame 708 is fixedly connected to the sixth motor 712. The top of the thread drill bit 709 is fixedly connected to the output end of the sixth motor 712. The high-pressure jet nozzle 711 is connected to an external high-pressure air source through an air pipe.

[0046] Those skilled in the art will understand that the fourth motor 704 drives the lead screw 703 to rotate, causing the lifting frame 706 to slide up and down along the second guide rod 705, thereby adjusting the height of the processed part. The fifth motor 707 drives the second and third station rotating frame 708 to rotate 120° each time. The bottom of the three plates of the second and third station rotating frame 708 is respectively equipped with a thread drill bit 709, a groove depth sensor 710, and a high-pressure air nozzle 711. The sixth motor 712 drives the thread drill bit 709 to rotate to complete the drilling process. The groove depth sensor 710 detects the drilling depth in real time to ensure processing accuracy. The high-pressure air nozzle 711... The air pipe is connected to an external high-pressure air source to blow away the iron filings generated during processing. The mechanism achieves precise height adjustment of the processed parts through lead screw lifting. The second and third station rotating frame 708 rotates intermittently by 120° to automate the switching between the three processes of drilling, inspection, and chip removal. This integrates the processing, inspection, and chip removal processes, significantly reducing the gap between processes and improving processing efficiency. At the same time, the real-time detection of the groove depth sensor 710 ensures the accuracy of drilling, and the chip removal function of the high-pressure air nozzle 711 prevents iron filings from affecting subsequent processing. The coordinated operation of all components achieves high-precision and high-efficiency multi-process processing.

[0048] Furthermore, the processing fixing mechanism 8 includes an L-shaped fixing frame 801 fixedly connected to the rear edge of the top of the processing table 1. The horizontal plate of the L-shaped fixing frame 801 is located directly above the right rotating base 104. A third hydraulic rod 802 is fixedly connected to the horizontal plate of the L-shaped fixing frame 801. A fixing pressure plate 803, which is vertically aligned with the right rotating base 104, is fixedly connected to the bottom output end of the third hydraulic rod 802. A third guide rod 804 is also fixedly connected to the top of the fixing pressure plate 803. The third guide rod 804 is slidably connected to the horizontal plate of the L-shaped fixing frame 801. A flexible pad 805 is fixedly connected to the bottom of the fixing pressure plate 803.

[0049] As will be understood by those skilled in the art, the third hydraulic rod 802 drives the fixed pressure plate 803 to move up and down, and the third guide rod 804 provides sliding guidance for the fixed pressure plate 803 to ensure the verticality of the pressing. The flexible pad 805 at the bottom of the fixed pressure plate 803 contacts the support frame body 105 to achieve pressing. This mechanism achieves stable pressing of the support frame body 105 by hydraulically driving the fixed pressure plate 803, ensuring that the support frame body 105 has no displacement or vibration during processing, thus improving processing accuracy. The guiding effect of the third guide rod 804 prevents the fixed pressure plate 803 from tilting during pressing. The design of the flexible pad 805 ensures the friction of pressing and effectively avoids damaging the surface of the support frame body 105, achieving flexible pressing and taking into account both the stability of the fixation and the protection of the workpiece.

[0050] The working principle and usage process of this device are as follows: One belt conveyor 101 conveys the material to the loading position. The three-station material handling mechanism 2 is activated. The first motor 201 drives the first three-station rotating frame 202 to rotate 120°. The first pneumatic gripper 207 moves downward under the drive of the first hydraulic rod 203, grips the support frame body 105 to be processed on the belt conveyor 101, and then moves upward. The second pneumatic gripper 207 moves the support frame body 105 to be processed into the placement slot 502 of the loading mechanism 5 on the left rotating base 104 and releases it, completing the loading. Subsequently, the reciprocating rotation mechanism 3 is activated. The second hydraulic rod 305 extends and drives the rack 304 to slide on the slide rail 303, through the first gear 302 and the first rotating shaft. The transmission of 301 drives the rotary disk 103 to rotate 180°, moving the left-side loading mechanism 5 to the right-side processing position. The processing fixing mechanism 8 is activated, and the third hydraulic rod 802 extends, causing the fixing plate 803 to move down. The flexible pad 805 securely presses the support frame body 105 into the placement groove 502. Then, the processing position adjustment mechanism 6 is activated, and the third motor 608 drives the worm gear 607 and worm wheel 605 to mesh and drive the second rotating shaft 602 and the second gear 603 to rotate. Through the external gear ring 604, the rotating base 104 and the loading mechanism 5 are rotated, adjusting the support frame body 105 to a suitable processing angle. The self-locking characteristic of the worm gear and worm wheel achieves angle positioning. After that, the three-station processing mechanism 7 is activated. The fourth motor 704 drives the lead screw 703 to rotate, causing the lifting frame 706 to move down along the second guide rod 705 to the processing height. The fifth motor 707 drives the second and third station rotating frame 708 to rotate 120°, rotating the thread drill bit 709 to the processing position. The sixth motor 712 drives the thread drill bit 709 to rotate to complete the drilling. After drilling, the second and third station rotating frame 708 rotates another 120°, rotating the groove depth sensor 710 to the detection position to detect the drilling depth in real time and ensure processing accuracy. After detection, the second and third station rotating frame 708 continues to rotate 120°, rotating the high-pressure air nozzle 711 to the chip removal position, using high-pressure gas provided by an external high-pressure air source to blow away the iron chips generated during processing, completing three steps. Processing steps: After processing is completed, the third hydraulic rod 802 of the processing fixing mechanism 8 retracts, driving the fixing plate 803 to move upward to release the pressure. The second hydraulic rod 305 of the reciprocating rotation mechanism 3 retracts, driving the rotating disk 103 to rotate 180° in the opposite direction, moving the processed support frame body 105 to the left loading and unloading position. The third pneumatic gripper 207 of the three-station material handling mechanism 2 moves downward to grip the processed support frame body 105 and then moves upward. The first three-station rotating frame 202 rotates 120°, moving the processed support frame body 105 to the unloading position of another belt conveyor 101. The pneumatic gripper 207 releases, and the support frame body 105 is transported by the belt conveyor 101 to the unloading area to complete the unloading.To process support frame bodies 105 of different specifications, pull the lever 420 of the quick-release connecting mechanism 4 to disengage the locking lever 416 from the locking groove 417. Rotate the handle 414 to rotate the rotating ring 411. Through the transmission between the arc-shaped drive groove 413 and the drive lever 410, pull the slider 406 to slide, causing the limiting block 407 to disengage from the annular limiting groove 409. Remove the original material-carrying mechanism 5 from the rotating base 104. Then, insert the circular insert 402 of the material-carrying mechanism 5, adapted to the new specification support frame body 105, into the circular slot 401. The rectangular guide block 404 and the rectangular guide groove 403 cooperate for positioning. Under the action of the first spring 408, the limiting block 407 is locked into the annular limiting groove 409 for fixation. Release the lever 420, and the locking lever 416 is locked into the locking groove 417 under the action of the second spring 419, completing the quick replacement of the material-carrying mechanism 5. Fully automatic processing of the new specification support frame body 105 can then be performed.
