As an important part of automobile structure and function, automobile steel pipe accessories, such as steel pipe components in the frame, suspension system and braking system, have a direct impact on the overall quality of the car due to their quality and precision.

Then, 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 device's adaptability to steel pipes of different lengths.

[0021] 2. The refined processing device for automobile parts processing can drive the connecting rod and the threaded rod to rotate by loosening the second fastening bolt and then turning the rotating disk. The threaded rod and the pentagonal nut are matched, and the unique movable rod and T-shaped slide rail design are used to achieve outward expansion of multiple connecting blocks, thereby accurately and firmly expanding and fixing steel pipes with different inner diameters. The operation process is simple and intuitive, and the fixing effect is reliable.

After the fixation is completed, tightening the second fastening bolt can stabilize the limit and ensure that the steel pipe remains stable during the processing, providing a solid foundation for refined processing.

[0022] 3. The fine processing device for automobile parts processing realizes the synchronous operation of continuous rotation of steel pipe and horizontal reciprocating movement of grinder through the coordinated operation of multiple gears and transmission belt driven by servo motor, so that grinder can act evenly on the surface of steel pipe, which greatly improves the uniformity of grinding and processing quality, and ensures that all parts of steel pipe can meet high-precision processing standards.

The two ends of the movable rod 25 are respectively movably connected to the first connecting seat 24 and the second connecting seat 26 through two connecting shafts 27. The connecting block 28 is welded to one end of the second connecting seat 26, and the second sliding block 29 is welded to one side of the connecting block 28. Multiple T-shaped slide rails 30 are all welded to the surface of one side of the chuck 15, and the second sliding block 29 is slidably connected to the T-shaped slide rail 30.

[0037] Loosen the second fastening bolt 19, and then rotate the rotating disk 20 to 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 the threaded fit, thereby driving multiple first connecting seats 24 to move. Under the action of the connecting 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 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, the pentagonal nut 23 will synchronously drive multiple connecting blocks 28 to expand outward when it moves, so as to achieve accurate and stable expansion and fixation of steel pipes with different inner diameters. When in use, there is no need to prepare a variety of fixing fixtures for steel pipes with different inner diameters, which greatly improves the versatility and processing efficiency of the device.

[0038] Embodiment three, as Figure 1-Figure 5As shown, a fine processing device for automobile parts processing, an L-shaped support plate 2 is welded to one side of a processing box 1, a servo motor 3 is detachably connected to one side of the L-shaped support plate 2, an output end of the servo motor 3 is provided with a coupling, the output end of the servo motor 3 passes through the L-shaped support plate 2 and is detachably connected to a rotating rod 12 through the provided coupling, a first gear 13 is welded to the outer surface of the rotating rod 12, a second gear 14 is welded to the outer surface of a rotating cylinder 11, the first gear 13 is meshed with the second gear 14, a chuck 15 is welded to one end of the rotating cylinder 11, a third gear 31 is welded to the outer surface of the rotating rod 12, a transmission toothed belt 32 is welded to the outer surface of the rotating rod 12, The outer surface of the third gear 31 is meshed, and the inner surface of the other end of the transmission belt 32 is meshed with the fourth gear 33.

The output end of the cylinder 39 passes through the connecting plate 38 and is detachably connected to the grinder 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, the rotating cylinder 11 and the chuck 15, the fixed steel pipe can be driven 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 34 rotate synchronously, so that the moving block 37 and the connecting plate 38 drive the cylinder 39 and the grinder 40 to reciprocate horizontally. After the cylinder 39 pushes the grinder 40 to fit the steel pipe and starts the grinder 40, the surface of the steel pipe can be ground. The coordinated operation of the multi-gear and transmission belt 32 realizes the synchronization of the rotation of the steel pipe and the horizontal reciprocating movement of the grinder 40, further improves the uniformity and processing quality of grinding, and avoids the deformation of the steel pipe due to excessive temperature due to long-term concentrated grinding at the same position.

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

[0041] After starting the grinding fluid pump 42, the grinding fluid can be extracted from the grinding fluid storage tank 41 through the extraction pipe 43, and then transported to the grinding position for spraying through the infusion pipe 44, which plays a cooling and lubricating role, improves the grinding accuracy, and at the same time washes down the debris, the debris is filtered through the filter plate 48, and the grinding fluid is circulated back to the grinding fluid storage tank 41, so as 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 movable frame 47 can be conveniently and stably pulled out, and the filtered debris can be cleaned in time to avoid clogging of the filter plate 48, reduce the difficulty and frequency of equipment maintenance, and ensure continuous and stable operation of the processing process.

[0042] Embodiment 5, as Figure 1-Figure 2 As shown, a fine processing device for processing automobile parts, the third guide rod 50 is welded to the top of the processing box 1, the two 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, the protective door 52 is slidably connected to the second linear slide rail 53, the transparent observation window 54 is detachably embedded in the surface of the protective door 52, 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 on both sides. With the cooperation of the third guide rod 50 and the second linear slide rail 53, the movement is smooth and stable whether the handle is pulled to open it to both sides or the steel pipe is fixed and then pulled to the center position to close it. When closing, the clamping block 56 on one side of one protective door 52 is accurately clamped into the clamping groove 55 opened on the other side of the other protective door 52, effectively closing the front end of the processing box 1 to prevent debris from splashing during grinding and ensure the safety of the operator. At the same time, the transparent observation window 54 provided on the protective door allows the operator to observe the processing of the steel pipe in the box in real time to ensure that the processing process is controllable.

[0044] It should be noted that the present invention is a fine processing device for processing automobile parts. When in use, the handle at the front section of the protective door 52 is pulled 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 the protective door 52 is opened, the first fastening bolt 8 is loosened to cancel the fixation of the first sliding block 7. At this time, the position of the fixed plate 9 can be adjusted horizontally, and then the distance between the two chucks 15 can be adjusted. After the distance between the two chucks 15 is adjusted to the same length as the steel pipe to be processed, the first fastening bolt 8 is tightened to fix the position of the fixed plate 9, and then the steel pipe can be placed between the two chucks 15, and then the second fastening bolt 19 is loosened, and then the rotating disk 20 is rotated to drive the limit block 18 and the connecting rod 17 to rotate, and at the same time, it will drive the threaded rod 21 and When the limit plate 22 rotates, the pentagonal nut 23 on the outer surface of the threaded rod 21 will move with the rotation, thereby driving the multiple first connecting seats 24 to move. When the first connecting seat 24 moves, it will drive one end of the movable rod 25 to move under the action of the connecting shaft 27, thereby pushing 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 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, it will synchronously drive the multiple connecting blocks 28 to expand outward, thereby expanding and fixing steel pipes with different inner diameters. After the steel pipe is fixed, the second fastening bolt 19 is tightened to fix the limit block 18. At this time, the fixation of the steel pipe is completed, and then the steel pipe can be finely processed.

[0045] After the steel pipe is fixed, the two protective doors 52 are pulled toward the center position so that the clamping block 56 on one side of the protective door 52 is clamped into the clamping groove 55 opened on the other side of the protective door 52. At this time, the front end of the processing box 1 can be closed to prevent debris from flying out during grinding and causing harm to the staff. At the same time, the processing status of the steel pipe in the processing box 1 can be observed at all times through the transparent observation window 54. When processing the steel pipe, the servo motor 3 is started to drive the rotating rod 12 to rotate. At this time, the first gear 13 will rotate with the rotation of the rotating rod 12. At this time, the second gear 14 will be driven to rotate synchronously under the meshing action. 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, the rotating cylinder 11 and the chuck 15 will be driven synchronously when the second gear 14 rotates. 5 rotates, which in turn drives the fixed steel pipe to rotate. At the same time, when the rotating rod 12 rotates, the third gear 31 is driven to rotate, and the fourth gear 33 and the reciprocating screw 34 are driven to rotate synchronously under the action of the transmission toothed belt 32. When the reciprocating screw 34 rotates, it drives the moving block 37 and the connecting plate 38 to reciprocate horizontally, and then drives the cylinder 39 and the grinder 40 to move. At this time, the grinder 40 is pushed by the cylinder 39 to move toward the outer surface of the steel pipe so that it fits with the surface of the steel pipe, and then the grinder 40 is started to grind and polish the surface of the steel pipe. Here, during the processing, the steel pipe will continue to rotate, and the grinder 40 will reciprocate horizontally, so that the surface of the steel pipe can be evenly polished, and at the same time, the problem of high temperature and deformation of the steel pipe caused by grinding the same position for a long time can be effectively solved.

[0046] At the same time, when the steel pipe is subjected to fine processing, the grinding fluid pump 42 is started. At this time, the grinding fluid in the grinding fluid storage box 41 will be extracted through the extraction pipe 43, and then transported through the infusion pipe 44 and sprayed out to spray the grinding position, which can cool and lubricate the grinding position, thereby improving the grinding accuracy. At the same time, the debris generated during grinding can be flushed down. Here, the flushed debris will fall to the surface of the filter plate 48 and will be filtered out.
