Description

Technical Field

[0001] This invention relates to the field of parts processing and polishing technology, specifically to a flipping device for processing and polishing automotive parts. Background Technology

[0002] In today's booming automotive manufacturing industry, the processing precision and surface quality of automotive parts directly affect the performance, safety, and service life of the entire vehicle. Among them, the grinding process, as a key step in the parts processing, plays an important role in removing burrs and oxide scale from the surface of the blank, correcting dimensional errors, and obtaining a flat and smooth surface. It plays an irreplaceable role in improving the assembly precision and reliability of parts.

[0003] In existing grinding processes, after grinding one side of a workpiece, an additional drive source, such as a servo motor or pneumatic cylinder, is needed to drive a specially designed flipping mechanism to flip the workpiece before grinding the other side can continue. This operating mode impacts costs in several ways: First, the procurement cost of the drive source itself, such as the price of a high-precision motor and the cost of the air pump and piping components for the cylinder, directly increases the initial cost of the equipment. Second, to achieve precise control of the flipping action, a complex power transmission structure, such as a gearbox, linkage mechanism, and a supporting control system, such as a PLC programming module and sensor feedback components, is required. This not only increases the difficulty of mechanical design and circuit integration but also further increases the manufacturing cost of the equipment. In addition, the long-term operation of the drive source and related components will generate continuous wear and tear, such as the periodic replacement of motor bearings and the aging maintenance of cylinder seals, leading to increased daily maintenance costs. At the same time, if the power system fails, such as a burnt-out motor or a leaking cylinder, not only will repair costs be incurred, but production will also be interrupted due to downtime for maintenance, indirectly increasing time costs and lost production capacity. In summary, this flipping mode, which relies on an additional driving source, involves high costs throughout the entire lifecycle of equipment manufacturing and daily operation, resulting in high overall costs and operating expenses for the grinding flipping device.

[0004] Therefore, it is necessary to invent a turning device for processing, grinding, and flipping automotive parts to solve the above problems. Summary of the Invention

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Example 1: This example provides a turning device for grinding and reversing automotive parts.

[0045] Please see Figure 1 - Figure 11As shown, the assembly includes a processing table 1, a through groove 37 in the middle of the processing table 1, a sliding groove 2 on the rear side of the processing table 1, a fixed frame 3 fixed to the upper end of the processing table 1, a through groove 4 in the middle of the fixed frame 3, a cylinder 5 fixed to the upper end of the fixed frame 3, a connecting seat 6 fixed to the driving end of the cylinder 5, a drive motor 7 fixed to the inner wall of the middle of the connecting seat 6, and a flexible polishing wheel 8 fixed to the driving end of the drive motor 7. The flexible polishing wheel 8 is a fiber wheel, which has good flexibility and elasticity. During the grinding and polishing process, it can better conform to the surface contour of the automotive parts. Whether it is a flat surface, a curved surface, or a complex corner, it can achieve uniform grinding, effectively avoiding surface damage to the parts that may be caused by rigid contact, while improving the surface smoothness after polishing. Moreover, the fiber wheel can be detached from the drive motor 7. This design brings many conveniences to daily use. When the fiber wheel wears or ages after long-term use, the staff does not need to replace the entire polishing assembly. They only need to remove the old fiber wheel and replace it with a new one, which greatly reduces maintenance costs and replacement time. In addition, depending on the material of different automotive parts, To meet the grinding precision requirements, the device can be easily replaced with fiber wheels of corresponding models or coarseness specifications, making it more adaptable and meeting diverse grinding and polishing needs, further enhancing the practical value of the equipment. A connecting block 9 is fixed to the rear side of the connecting seat 6. A connecting structure is provided at the other end of the connecting block 9. The connecting structure includes a connecting frame 10, with a fixed block 11 rotatably connected to the other end of the connecting frame 10. A sliding frame 12 is fixed to the other end of the fixed block 11. A slider 13 is slidably connected to the inner wall of the sliding frame 12. Several springs 14 are fixed to one end of the slider 13. The upper side of the slider 13... A rack 15 is fixed, and a pressing rod 16 is slidably connected to one corner of the slider 13. A pressing frame 17 is fixed to one side of the slide groove 2. The outer surface of the pressing rod 16 can slide along the upper surface of the pressing frame 17, and the pressing frame 17 penetrates the inner wall of the slider 13 and forms a sliding fit with the slider 13. The rack 15 is intermittently meshed with a drive gear 18. A fixing rod 19 is fixed in the middle of the drive gear 18. A fixing fixture 20 is fixed at the other end of the fixing rod 19. Two clamps 21 are slidably connected to the inner wall of the fixing fixture 20. One end of the two clamps 21 is threadedly connected to a bidirectional threaded rod 22.

[0046] In this embodiment, the upper end of the connecting frame 10 is rotatably connected to one end of the connecting block 9, and the lower end of the connecting frame 10 is rotatably connected to one end of the fixing block 11. The other end of the fixing block 11 is fixed to one corner of the sliding frame 12. The outer surface of the sliding frame 12 is slidably connected to the inner wall of the slide groove 2. The outer surface of the extrusion rod 16 is slidably connected to the side of the slider 13 near the fixing block 11. The outer surface of the extrusion rod 16 is slidably connected to the outer surface of the extrusion frame 17. The inner wall of the slider 13 is slidably connected to the outer surface of the extrusion frame 17. One side of the extrusion frame 17 is fixed to one side of the slide groove 2. One end of the extrusion frame 17 is arc-shaped, and the other end of the extrusion frame 17 is inclined. The outer surface of the slider 13 is slidably connected to the inner wall of the sliding frame 12. One side of the slider 13 is fixed to one end of several springs 14, and the other end of several springs 14 is fixed to the inner wall of one side of the sliding frame 12. The lower end of the rack 15 is fixed. On one side of the upper end of the slider 13, the rack 15 is lower than the upper surface of the slider 13. The rack 15 meshes with the drive gear 18, and there is a certain gap between the rack 15 and the drive gear 18. The middle of the drive gear 18 is fixed to one end of the fixed rod 19, and the other end of the fixed rod 19 is fixed to the middle of one side of the fixed fixture 20. The outer surface of the fixed rod 19 is rotatably connected to the inner wall of one side of the processing table 1. The outer surfaces of the two clamps 21 are slidably connected to the inner walls of both sides of the fixed fixture 20. One end of the two clamps 21 is threadedly connected to the outer surfaces of both sides of the bidirectional threaded rod 22. The outer surface of the bidirectional threaded rod 22 is rotatably connected to the inner wall of one side of the fixed fixture 20. One end of the connecting block 9 is fixed to one side of the connecting seat 6. The outer surface of the connecting block 9 is slidably connected to the inner wall of the through groove 4. The through groove 4 passes through the middle of the fixed frame 3. The vertical section of the fixed frame 3 is L-shaped. Figure 1 - Figure 10 As shown.

[0047] The specific implementation process is as follows: When the cylinder 5 drives the connecting seat 6 to move, it will simultaneously drive the drive motor 7 fixed on the inner wall of the connecting seat 6 to move down. The drive motor 7 starts synchronously during the downward movement, and the flexible polishing wheel 8 fixed at its drive end rotates accordingly to perform polishing operations on the surface of the automotive parts.

[0048] At the same time, the connecting block 9, which is fixed to one side of the connecting seat 6, moves down synchronously under the limiting action of the through groove 4 in the middle of the fixing frame 3. The moving connecting block 9, through the connecting frame 10 rotatably connected to the other end, drives the fixing block 11 rotatably connected to the other end of the connecting frame 10 to slide along the slide groove 2. The sliding fixing block 11 further drives the sliding frame 12 fixed at the end to slide in the same direction in the slide groove 2. The rack 15 fixed to one side of the upper end of the sliding frame 12 moves together with it.

[0049] When cylinder 5 drives connecting seat 6 to move connecting block 9 downward, connecting block 9 is driven by connecting frame 10 and fixed block 11, causing sliding frame 12 to move from one side to the other under the limit of slide groove 2, gradually approaching extrusion frame 17 fixed on the other side of slide groove 2. The rotating sliding frame 12 drives slider 13, which is slidably connected to the inner wall, to move synchronously, and extrusion rod 16, which is slidably connected to one corner of slider 13, moves accordingly. When extrusion rod 16 contacts the arc surface at one end of extrusion frame 17, it moves upward under the guidance of the arc surface; as sliding frame 12 and slider 13 continue to slide, the outer surface of extrusion rod 16 slides along the upper surface of extrusion frame 17 until sliding frame 12 and slider 13 approach the other edge of extrusion frame 17, extrusion rod 16 moves to the inclined side of extrusion frame 17 and moves downward to fit the inclined surface under the action of gravity. At this time, cylinder 5 completes the position adjustment of connecting seat 6, drive motor 7 drives flexible polishing wheel 8 to rotate continuously, and polishes and grinds the fixed automotive parts fixed by the fixed fixture 20 through two clamps 21 and the bidirectional threaded rod 22.

[0050] Once one side of the component is polished, cylinder 5 drives connecting seat 6 to move connecting block 9 upwards. Connecting block 9, through connecting frame 10 and fixed block 11, drives sliding frame 12 to move along slide groove 2 away from extrusion frame 17. The moving sliding frame 12 drives slider 13 and extrusion rod 16 to move synchronously. After extrusion rod 16 contacts the inclined surface of extrusion frame 17, under the extrusion action of the inclined surface, it drives slider 13 to slide inwards towards sliding frame 12, compressing several springs 14 fixed on the other side of slider 13. At this time, rack 15 fixed at the upper end of slider 13 just meshes with drive gear 18. As slider 13 continues to move, rack 15 drives drive gear 18 to rotate. Drive gear 18 drives fixed fixture 20 to rotate through fixed rod 19 fixed in the middle. Fixed rod 19 is supported by the inner wall of one side of processing table 1. When the extrusion rod 16 moves to the arc-shaped surface of the extrusion frame 17, the extrusion effect disappears, the compressed spring 14 pushes the slider 13 to reset, the rack 15 disengages from the drive gear 18, and the plane of the slider 13 contacts the tooth surface of the drive gear 18 to form a positioning, keeping the fixed fixture 20 stable. Then the cylinder 5 drives the connecting seat 6 to move down again, and so on, using the flexible polishing wheel 8 to polish the other side of the parts, achieving the effect of automatic flipping without the need for a separate drive source, thereby reducing the cost of the polishing and flipping device and its use.

[0051] In Example 2, after the grinding process of automotive parts is completed, metal shavings and abrasive residues easily adhere to the workpiece surface. In the traditional workflow, operators need to clean the shavings simultaneously while flipping the workpiece. This intermittent operation not only disrupts the continuity of the operation but also increases the idle waiting time of the equipment. To solve this problem, technological innovation is needed to achieve seamless connection between the grinding and flipping processes, reduce the time spent on unnecessary steps, thereby significantly improving the overall operating efficiency of the grinding and flipping device and optimizing the overall processing cycle of automotive parts.

[0052] Please refer to Figure 1 - Figure 11 as shown, on the basis of the first embodiment, the functions of flipping and blowing-off are added;

[0053] Please refer to again Figure 1 - Figure 11 as shown, a rotating rod 23 is fixed in the middle of the other side of the fixing fixture 20, a transmission gear 24 is fixed at the other end of the rotating rod 23, the transmission gear 24 is meshed with a driven gear 25, a rotating frame 26 is fixed in the middle of the driven gear 25, a fan impeller 27 is fixed in the middle of the rotating frame 26, ventilation holes 28 are formed on both sides of the processing table 1, diversion frames 29 are arranged at the openings of the other ends of the two ventilation holes 28, one end of the rotating rod 23 is fixed in the middle of one side of the fixing fixture 20, the other end of the rotating rod 23 is fixed in the middle of the transmission gear 24, the outer surface of the rotating rod 23 is rotatably connected to the inner wall of the other side of the processing table 1, the transmission gear %24 is meshed with the driven gear 25, the middle of the driven gear 25 is fixed at one end of the rotating frame 26, the outer surface of the rotating frame 26 is rotatably connected to the inner wall of the processing table 1, the vertical section of the rotating frame 26 is in a cross shape, the middle of the fan impeller 27 is fixed in the middle of the rotating frame 26, the cross sections of the two ventilation holes 28 are both in an L shape, the two diversion frames 29 are arranged oppositely, and the vertical sections of the two diversion frames 29 are both in a V shape.

[0054] The specific implementation process is as follows: When the connecting seat 6 is driven to move by the cylinder 5, the connecting block 9 fixed to the connecting seat 6 will带动 the sliding frame 12 to move synchronously through the connecting frame 10 and the fixing block 11. The moving sliding frame 12 drives the rack 15 fixed thereto to drive the driving gear 18 to rotate by means of the slider 13 sliding on the inner wall. When the driving gear 18 rotates, the fixing fixture 20 is driven to complete the flipping action by the fixing rod 19 fixed in the middle; during the flipping process of the fixing fixture 20, the rotating rod 23 fixed in the middle of the other side will rotate synchronously, and the rotating rod 23 maintains a stable rotating state under the support of the inner wall of the other side of the processing table 1;

[0055] When the rotating rod 23 rotates, the transmission gear 24 fixed at the other end thereof will rotate accordingly, and the transmission gear 24 further drives the driven gear 25 meshed with it to rotate synchronously. Due to the large gear ratio design of the transmission gear 24 and the driven gear 25, only a small rotation of the transmission gear 24 can enable the driven gear 25 to rotate multiple circles quickly. The rapid rotation of the driven gear 25 will带动 the rotating frame 26 fixed in the middle thereof to rotate stably and at high speed under the limiting action of the inner wall of the processing table 1, and further带动 the fan impeller 27 fixed in the middle of the rotating frame 26 to rotate synchronously at high speed;

[0056] When the impeller 27 rotates, it accelerates the rapid flow of air. The air enters through the inlets of the two vents 28 and exits through the outlets, then enters the guide frames 29 fixed on both sides of the processing table 1. The two guide frames 29 direct the airflow to the automotive parts during the flipping process, efficiently blowing away the debris attached to their surfaces. This achieves a combined flipping and blowing effect, effectively improving the continuity of the processing operation and thus increasing the working efficiency of the grinding and flipping device.

[0057] Example 3: During the grinding of automotive parts, the generated debris will splash and scatter on the processing table, which requires workers to spend extra time and effort to clean it up. Therefore, it is necessary to equip the processed table with an automatic cleaning function to bring convenience to the workers.

[0058] Please see Figure 1 - Figure 11 As shown, an automatic cleaning and collection function has been added based on Embodiment 1;

[0059] Please refer to it again. Figure 1 - Figure 11 As shown, two connecting brackets 30 are rotatably connected to the other end of the connecting block 9. Each connecting bracket 30 has a sliding block 31 rotatably connected to its other end. Brush holders 32 are fixed to the adjacent sides of the two sliding blocks 31. Guide grooves 33 are provided on both sides of the processing table 1. A fixed seat 34 is fixed to the lower end of the processing table 1. A collection box 35 is provided on the inner wall of the fixed seat 34. Support legs 36 are fixed to the four corners of the lower end of the fixed seat 34. The adjacent ends of the two connecting brackets 30 are rotatably connected to one end of the connecting block 9. The two sliding blocks 31 are rotatably connected to one end of the two sliding blocks 31 at their respective ends. The outer surfaces of the two sliding blocks 31 are slidably connected to the inner walls of the two guide grooves 33. The two brush holders 32 are fixed at their respective ends to the adjacent sides of the two sliding blocks 31. The bristles of the two brush holders 32 are attached to the upper surfaces of both sides of the processing table 1. The upper end of the fixed seat 34 is fixed to the middle of the lower side of the processing table 1. The outer surface of the collection box 35 is in contact with the inner wall of the fixed seat 34. The collection box 35 is located below the through groove 37, which runs through the middle of the processing table 1.

[0060] The specific implementation process is as follows: When the connecting seat 6 is moved by the cylinder 5, the connecting block 9 fixed to the connecting seat 6 will drive the two sliding blocks 31 to move in opposite directions under the limiting action of the guide grooves 33 on both sides of the processing table 1 through the two connecting frames 30 rotatably connected to the other end. When the cylinder 5 drives the connecting seat 6 to move down, the two sliding blocks 31 move away from each other. As the two sliding blocks 31 separate, the two brush holders 32 fixed on their adjacent sides also separate. When the connecting seat 6 moves down to the processing height under the drive of the cylinder 5, the drive motor 7 fixed to the connecting seat 6 will drive the flexible polishing wheel 8 to rotate, and perform grinding and polishing operations on the automotive parts clamped between the two clamps 21.

[0061] After the grinding and polishing operation is completed, cylinder 5 drives connecting seat 6 to move upward. At this time, connecting block 9 will drive two sliding blocks 31 in the opposite direction through two connecting brackets 30, and they will move closer to each other under the limit of guide groove 33. As the sliding blocks 31 move closer, the two brush holders 32 close synchronously to clean up the debris splashed on the surface of the processing table 1. The cleaned debris will be pushed to the through groove 37 in the middle of the processing table 1 and fall into the collection box 35 below through the through groove 37. It can be emptied periodically. The collection box 35 is placed on the fixed seat 34 on the lower side of the processing table 1 and the fixed seat 34 is fixedly connected to the lower side of the processing table 1. This achieves the effect of automatic cleaning and collection, eliminating the need for additional cleaning work by the staff, bringing convenience to the staff and improving the ease of use of the grinding and turning device.

[0062] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
