[0002] With the rapid development of the automobile industry, the requirements for the performance, safety and comfort of automobiles are constantly increasing. As an important part of the structure and function of automobiles, such as the steel pipe components in the frame, suspension system and braking system, the quality and precision of automobile steel pipe parts directly affect the overall quality of automobiles. Consumers' expectations for the quality of automobiles are growing day by day, and it is required that automobile parts have higher reliability and durability.

[0003] When the existing automobile parts processing and treatment devices process steel pipes with different lengths and inner diameters, the methods of adjusting the spacing and fixing the parts are cumbersome and inefficient, and it is necessary to frequently replace the tooling and fixtures, which not only consumes a lot of time and manpower, but also is difficult to ensure the consistency of processing precision. At the same time, in the grinding process, the rotation of the steel pipe and the movement of the grinding equipment lack effective coordination, resulting in poor grinding uniformity and a high rejection rate, which brings certain adverse effects to the use process.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. For the fine processing device for automobile parts processing, by simply loosening or tightening the first fastening bolt, the fixed state of the first sliding block can be quickly switched. Immediately afterwards, the operator can easily adjust the horizontal position of the fixed plate, and then accurately adjust the distance between the two chucks. This design greatly enhances the adaptability of the device to steel pipes of different lengths. During the actual processing, without the cumbersome steps of changing tooling, the preparation process can be quickly completed, effectively shortening the preparation time before processing, and providing a strong guarantee for improving the overall processing efficiency.

[0021] 2. For the fine processing device for automobile parts processing, by loosening the second fastening bolt and then rotating the rotating disk, the connecting rod and the threaded rod can be driven to rotate. By utilizing the threaded cooperation between the threaded rod and the pentagonal nut, as well as the unique design of the movable rod and the T-shaped slide rail, multiple connecting blocks can be expanded outwards, so as to accurately and stably expand and fix steel pipes with different inner diameter sizes. The operation process is simple and intuitive, and the fixing effect is reliable. There is no need to prepare multiple fixing jigs for steel pipes with different inner diameters, greatly improving the versatility and processing efficiency of the device. And after the fixing is completed, tightening the second fastening bolt can achieve stable limiting, ensuring that the steel pipe remains stable during the processing, providing a solid foundation for fine processing.

[0022] 3. For the fine processing device for automobile parts processing, through the coordinated operation of the servo motor driving the multi-gear and the transmission belt, the continuous rotation of the steel pipe and the horizontal reciprocating movement of the grinding machine are synchronized, enabling the grinding machine to act evenly on the surface of the steel pipe, greatly improving the uniformity of grinding and the processing quality, ensuring that all parts of the steel pipe can meet the high-precision processing standards. At the same time, it can effectively avoid the problem of deformation of the steel pipe caused by overheating due to long-term concentrated grinding at the same position. It not only ensures the processing accuracy of the steel pipe but also reduces the rejection rate. The coordinated cooperation of multiple components fully demonstrates the excellent performance of this device in improving processing efficiency and ensuring processing quality.

[0023] 4. The fine processing device for automobile parts can quickly pump out the grinding fluid in the processing tank and spray it to the grinding position through the set grinding fluid pump, effectively playing the roles of cooling and lubrication, greatly improving the grinding accuracy, ensuring the processing quality. At the same time, the grinding fluid flushes down the debris. After being filtered by the filter screen plate, the grinding fluid circulates back into the grinding fluid storage tank, realizing the efficient utilization of resources, reducing the production cost. In addition, with the help of the first linear slide rail and the handle, the moving frame can be conveniently and stably pulled out to timely clean the filtered debris, avoid clogging of the filter screen plate, ensure the filtering efficiency while reducing the equipment maintenance difficulty and frequency, and make the processing process run continuously and stably.

[0024] 5. The fine processing device for automobile parts has a double-sided opening design for the protective door. With the cooperation of the third guide rod and the second linear slide rail, it moves smoothly. When closed, the clamping block set on one side of one protective door is precisely clamped with the clamping groove opened on one side of the other protective door, effectively closing the front end of the processing tank, preventing debris from splashing during the grinding process, providing reliable safety protection for the operator. And the setting of the transparent observation window does not affect the operator's real-time observation of the processing situation, ensuring the controllability of the processing process.

[0033] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0034] Example 1, as Figure 3 , Figure 4 , Figure 7 shown, a fine processing device for automobile parts processing, the fixed frame 4 is welded inside the processing box 1, the inner side of the fixed frame 4 is inclined, a plurality of fixed blocks 5 are all welded to the upper end of the fixed frame 4, the first guide rod 6 is welded between the two fixed blocks 5, the first sliding block 7 is slidably connected to the outer surface of the first guide rod 6, the first fastening bolt 8 is threadedly connected to the first sliding block 7, and the fixed plate 9 is welded to the upper ends of the two first sliding blocks 7.

[0035] When operating the steel pipe processing device, loosen the first fastening bolt 8, cancel the fixation of the first sliding block 7, adjust the horizontal position of the fixed plate 9, change the distance between the two chucks 15, and when the distance between the two chucks 15 is consistent with the length of the steel pipe to be processed, tighten the first fastening bolt 8 to fix the position of the fixed plate 9. Subsequently, the steel pipe can be placed between the two chucks 15 for fixation, enhancing the adaptability of the device to steel pipes of different lengths and effectively shortening the preparation time before processing.

[0036] Example 2, as Figure 3 , Figure 4 ,Figure 5 , Figure 6 , Figure 7 As shown in Figure 7 , a fine processing device for automobile parts processing, a first bearing ring 10 is detachably embedded on one side of the processing box 1, and another first bearing ring 10 is detachably embedded at the center of the fixing plate 9. The rotating cylinder 11 is rotatably connected to the first bearing ring 10. The chuck 15 is welded to one end of the rotating cylinder 11. Two second bearing rings 16 are respectively detachably embedded at the centers of the two chucks 15. The connecting rod 17 is rotatably connected to the second bearing ring 16.

The rotating disk 20 is welded to one side of the limiting block 18. The threaded rod 21 is welded to the other end of the second bearing ring 16. The limiting plate 22 is welded to the other end of the threaded rod 21. The pentagonal nut 23 is threadedly connected to the outer surface of the threaded rod 21. A plurality of first connecting seats 24 are respectively welded to the surface of the pentagonal nut 23. Both ends of the movable rod 25 are movably connected to the first connecting seat 24 and the second connecting seat 26 through two connecting rotating shafts 27 respectively. The connecting block 28 is welded to one end of the second connecting seat 26. The second sliding block 29 is welded to one side of the connecting block 28. A plurality of T-shaped sliding rails 30 are all welded to the surface of one side of the chuck 15. The second sliding block 29 is slidably connected to the T-shaped sliding rail 30.

[0037] Loosen the second fastening bolt 19, and then rotating the rotating disk 20 can drive the connecting rod 17 and the threaded rod 21 to rotate. When the threaded rod 21 rotates, the pentagonal nut 23 on its outer surface will move due to thread fit, and then drive a plurality of first connecting seats 24 to move. Under the action of the connecting rotating shaft 27, the first connecting seat 24 drives one end of the movable rod 25 to move, and pushes the second connecting seat 26 and the connecting block 28 at the other end of the movable rod 25 to move. Since the second sliding block 29 is welded to one side of the connecting block 28, the T-shaped sliding rail 30 is welded to one side of the chuck 15, and the second sliding block 29 is slidably connected to the T-shaped sliding rail 30, when the pentagonal nut 23 moves, it will synchronously drive a plurality of connecting blocks 28 to expand outwards, realizing precise and stable expansion and fixation of steel pipes with different inner diameter sizes. When in use, there is no need to prepare a variety of fixing jigs for steel pipes with different inner diameters, which greatly improves the versatility and processing efficiency of the device.

[0038] Example 3, as Figures 1 - 5As shown in the figure, a fine processing device for automobile parts processing. The L-shaped support plate 2 is welded to one side of the processing box 1. The servo motor 3 is detachably connected to one side of the L-shaped support plate 2. A coupling is provided at the output end of the servo motor 3. The output end of the servo motor 3 passes through the L-shaped support plate 2 and is detachably connected to the rotating rod 12 through the provided coupling. The first gear 13 is welded to the outer surface of the rotating rod 12. The second gear 14 is welded to the outer surface of the rotating cylinder 11. The first gear 13 meshes with the second gear 14. The chuck 15 is welded to one end of the rotating cylinder 11. The third gear 31 is welded to the outer surface of the rotating rod 12. The transmission belt 32 meshes with the outer surface of the third gear 31. The other end inner surface of the transmission belt 32 meshes with the fourth gear 33. The fourth gear 33 is welded to the outer surface of the reciprocating screw rod 34. The bearing seat 35 is welded to one side of the processing box 1. The reciprocating screw rod 34 is rotatably connected to the bearing seat 35. The second guide rod 36 is welded inside the processing box 1. The two moving blocks 37 are respectively threadedly connected and slidably connected to the outer surfaces of the reciprocating screw rod 34 and the second guide rod 36. The connecting plate 38 is welded between the two moving blocks 37. The cylinder 39 is detachably connected to the upper end of the connecting plate 38. The output end of the cylinder 39 passes through the connecting plate 38 and is detachably connected to the grinding machine 40.

[0039] When the servo motor 3 drives the rotating rod 12 to rotate, it can drive the first gear 13 to rotate, and then drive the second gear 14 meshing with it to rotate synchronously. Due to the welding relationship between the second gear 14 and the rotating cylinder 11 and the chuck 15, it can drive the fixed steel pipe to rotate continuously. At the same time, when the rotating rod 12 rotates, it can drive the third gear 31 to rotate. At this time, under the action of the transmission belt 32, the fourth gear 33 and the reciprocating screw rod 34 rotate synchronously, so that the moving blocks 37 and the connecting plate 38 drive the cylinder 39 and the grinding machine 40 to move horizontally back and forth. The cylinder 39 pushes the grinding machine 40 to fit the steel pipe and then starts the grinding machine 40, so that the surface of the steel pipe can be ground. The coordinated operation of this multi-gear and the transmission belt 32 realizes the synchronization of the rotation of the steel pipe and the horizontal reciprocating movement of the grinding machine 40, further improving the uniformity of grinding and the processing quality, and avoiding the deformation of the steel pipe due to overheating at the same position during long-term concentrated grinding.

[0040] Example 4, as Figures 1 - 4 As shown in the figure, a fine processing device for automobile parts processing. The grinding fluid storage tank 41 is welded to the lower end of the processing box 1 and is communicated with the inside of the processing box 1. The grinding fluid pump 42 is detachably connected to the top of the processing box 1. The liquid suction pipe 43 is detachably connected to the upper end of the grinding fluid pump 42. The other end of the liquid suction pipe 43 is inserted into the grinding fluid storage tank 41. The liquid delivery pipe 44 is detachably connected to one side of the grinding fluid pump 42. The pipe clamp 45 is welded to one side of the connecting plate 38. The other end of the liquid delivery pipe 44 is inserted into the pipe clamp 45. The two first linear slide rails 46 are symmetrically welded to the bottom of the processing box 1. The moving frame 47 is slidably connected to the upper ends of the two first linear slide rails 46. The filter mesh plate 48 is detachably embedded in the moving frame 47.

[0041] After starting the grinding fluid pump 42, grinding fluid can be pumped out from the grinding fluid storage tank 41 through the liquid suction pipe 43, and then transported to the grinding position for spraying through the liquid delivery pipe 44, playing a role in cooling and lubrication, improving the grinding accuracy, and at the same time flushing down the debris. The debris is filtered by the filter screen plate 48, and the grinding fluid is recycled back to the grinding fluid storage tank 41 to achieve efficient utilization and reduce production costs. In addition, with the help of the first linear slide rail 46 and the handle 49, the moving frame 47 can be conveniently and stably pulled out to timely clean the filtered debris, avoid clogging of the filter screen plate 48, reduce the difficulty and frequency of equipment maintenance, and ensure the continuous and stable operation of the processing process.

[0042] Example Five, as Figures 1 - 2 shown, a fine processing device for automobile parts processing, the third guide rod 50 is welded to the top of the processing box 1, both L-shaped sliders 51 are slidably connected to the outer surface of the third guide rod 50, the protective door 52 is welded to the lower end of the L-shaped slider 51, the second linear slide rail 53 is welded to the front end of the processing box 1, and the protective door 52 is slidably connected to the second linear slide rail 53. The transparent observation window 54 is detachably embedded on the surface of the protective door 52, and the clamping block 56 is welded to one side of the protective door 52, and the clamping block 56 is clamped in the clamping groove 55.

[0043] The protective door 52 is designed to open bilaterally. With the cooperation of the third guide rod 50 and the second linear slide rail 53, whether pulling the handle to open it to both sides or pulling it to the central position to close it after fixing the steel pipe, the movement is smooth and stable. When closing, the clamping block 56 on one side of the protective door 52 is accurately clamped into the clamping groove 55 opened on one side of the other protective door 52, effectively closing the front end of the processing box 1 to prevent debris from splashing during grinding processing and ensuring the safety of the operator. At the same time, the transparent observation window 54 provided on the protective door facilitates the operator to observe the processing situation of the steel pipe in the box in real time and ensure the controllability of the processing process.

[0044] It should be noted that the present invention is a fine processing device for automobile parts processing. When in use, pull the handle at the front section of the protective door 52 to drive the two protective doors 52 to open to both sides. Here, under the action of the third guide rod 50 and the second linear slide rail 53, the protective door 52 can move more smoothly. After opening the protective door 52, loosen the first fastening bolt 8 to cancel the fixation of the first sliding block 7. At this time, the position of the fixed plate 9 can be horizontally adjusted, and then the distance between the two chucks 15 can be adjusted. After adjusting the distance between the two chucks 15 to be the same as the length of the steel pipe to be processed, tighten the first fastening bolt 8 to fix the position of the fixed plate 9. Then, the steel pipe can be placed between the two chucks 15. Next, loosen the second fastening bolt 19, and then rotate the rotating disk 20 to drive the limiting block 18 and the connecting rod 17 to rotate. At the same time, the threaded rod 21 and the limiting plate 22 will be driven to rotate. When the threaded rod 21 rotates, the pentagonal nut 23 on its outer surface will move along with its rotation, and then drive a plurality of first connecting seats 24 to move. When the first connecting seat 24 moves, one end of the movable rod 25 will be driven to move under the action of the connecting rotating shaft 27, and then the second connecting seat 26 and the connecting block 28 at the other end of the movable rod 25 will be pushed to move. Since the second sliding block 29 is welded to one side of the connecting block 28, the T-shaped slide rail 30 is welded to one side of the chuck 15, and the second sliding block 29 is slidably connected to the T-shaped slide rail 30, when the pentagonal nut 23 moves, a plurality of connecting blocks 28 will be synchronously driven to expand outwards, so as to expand and fix steel pipes with different inner diameters. After the steel pipe is fixed, tighten the second fastening bolt 19 to fix the limiting block 18. At this time, the fixation of the steel pipe is completed, and then the fine processing of the steel pipe can be carried out.

[0045] After the steel pipe is fixed, pull the two protective doors 52 towards the center position, so that the clamping block 56 on one side of a protective door 52 is inserted into the clamping groove 55 opened on one side of the other protective door 52. At this time, the front end of the processing box 1 can be closed, avoiding the flying of debris during grinding from causing harm to the staff. At the same time, under the action of the transparent observation window 54, the processing situation of the steel pipe in the processing box 1 can be observed at all times. When processing the steel pipe, start the servo motor 3 to drive the rotating rod 12 to rotate. At this time, the first gear 13 will rotate together with the rotation of the rotating rod 12. At this time, under the meshing action, the second gear 14 will be driven to rotate synchronously. Since the second gear 14 is welded to the outer surface of the rotating cylinder 11 and the chuck 15 is welded to one end of the rotating cylinder 11, when the second gear 14 rotates, the rotating cylinder 11 and the chuck 15 will be driven to rotate synchronously, and then the fixed steel pipe will be driven to rotate. At the same time, when the rotating rod 12 rotates, the third gear 31 will be driven to rotate, and under the action of the transmission belt 32, the fourth gear 33 and the reciprocating lead screw 34 will rotate synchronously. When the reciprocating lead screw 34 rotates, it will drive the moving block 37 and the connecting plate 38 to move horizontally back and forth, and then be able to drive the cylinder 39 and the grinding machine 40 to move. At this time, the cylinder 39 is used to push the grinding machine 40 towards the outer surface of the steel pipe to make it fit the surface of the steel pipe, and then start the grinding machine 40 to grind and polish the surface of the steel pipe. Here, during the processing, the steel pipe will continue to rotate, and the grinding machine 40 will move horizontally back and forth. Therefore, the surface of the steel pipe can be evenly polished, and at the same time, the problem that the temperature of the steel pipe rises and deforms due to long-term grinding at the same position can be effectively solved.

[0046] At the same time, when carrying out fine processing on the steel pipe, start the grinding fluid pump 42. At this time, the grinding fluid in the grinding fluid storage tank 41 will be pumped out through the liquid extraction pipe 43, and then sprayed out after being transported through the liquid delivery pipe 44 to spray the grinding position, which can play a role in cooling, lubricating, etc. for the grinding position, and then improve the grinding accuracy.
