Description

Technical Field

[0001] This invention relates to the field of machining fixture technology, and in particular to a quick clamping device for preventing deformation of thin-walled parts. Background Technology

[0002] Thin-walled conical parts (such as atomizing discs) are core components of precision equipment such as spray drying and fluid conveying. Their overall structure is thin and has extremely poor rigidity. During precision machining processes such as inclined hole drilling, inner wall grinding, and end face finishing, they are prone to buckling, warping, denting, or springback deformation due to uneven stress. This can lead to dimensional deviations, roundness and flatness not meeting standards, and in severe cases, directly causing parts to be scrapped, significantly increasing production costs.

[0003] Currently, the industry commonly uses traditional three-jaw chucks, ordinary flat-jaw vises, or simple clamping plate fixtures for clamping such thin-walled parts. These traditional fixtures have many unresolved drawbacks: Firstly, clamping methods are mostly point contact or line contact, with small contact area and highly concentrated force, making it difficult to precisely control the clamping force. Large variations in force during manual operation can easily cause irreversible deformation of thin-walled parts. Secondly, traditional fixtures have cumbersome clamping processes, requiring repeated manual alignment and adjustment of the clamping position. Furthermore, poor positioning consistency and repeated disassembly and assembly can lead to cumulative positioning errors, failing to guarantee the uniformity of machining accuracy for batches of parts. Moreover, traditional fixtures cannot effectively protect the surface of parts during machining, easily causing appearance defects such as clamping scratches and marks. Simultaneously, machining debris can easily enter the internal cavities of the parts, causing blockages and affecting subsequent performance. These issues make it difficult to meet the urgent needs of the precision manufacturing field for high-precision, high-efficiency, and low-cost batch machining of thin-walled parts. To solve these problems, we propose a rapid clamping device for preventing deformation of thin-walled parts. Summary of the Invention

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] like Figures 1-7As shown, a quick clamping device for preventing deformation of thin-walled parts includes a base plate 1. Four support columns 12 are provided on the top side wall of the base plate 1. The same support plate 13 is fixedly connected to the outer side wall of the four support columns 12. The support plate 13 has two slide bars 112 at its top. A guide mechanism 2 for guiding the parts is provided on one side wall of the support plate 13. A clamping and positioning mechanism 3 for clamping and positioning the parts is slidably connected to the outer side wall of the support columns 12.

[0021] In this embodiment, the clamping and positioning mechanism 3 includes a positioning box 31 slidably connected to the outer wall of the support column 12. A cover plate 38 is rotatably connected to the bottom end of the positioning box 31. A seventh gear 37 is rotatably connected to the inner wall of the cover plate 38. A support frame 34 is provided on the top side wall of the cover plate 38. A fourth motor 35 is provided on the side wall of the support frame 34. A sixth gear 36 is provided at the output end of the fourth motor 35. The sixth gear 36 meshes with the outer wall of the seventh gear 37. A third motor 32 is provided at the top of the inner wall of the positioning box 31. A fifth gear 33 is provided at the output end of the third motor 32. The outer wall of the fifth gear 33 meshes with the outer wall of the cover plate 38. A rotating plate 39 is provided at the bottom end of the seventh gear 37. A first sliding plate is provided at the top of the rotating plate 39. The bottom end of the cover plate 38 is provided with a second sliding groove 311. A movable plate 313 is slidably connected to the inner side wall of the second sliding groove 311. A sliding column 312 is provided at the top of the movable plate 313. The outer side wall of the sliding column 312 is slidably connected to the inner side wall of the first sliding groove 310. A clamping plate 314 is provided at the bottom end of the movable plate 313. A fixing column 315 is provided at the top of the inner side wall of the positioning box 31. The other end of the fixing column 315 passes through the cover plate 38 and is provided with a positioning plate 316. Multiple positioning grooves 317 are provided on the bottom side wall of the positioning plate 316. A signal sensor 318 is provided at the top of the inner side wall of the positioning groove 317. An elastic component 319 is provided at the top of the inner side wall of the positioning groove 317. A protrusion 320 is provided at the other end of the elastic component 319.

[0022] Specifically, the fourth motor 35 is activated, driving the sixth gear 36 to rotate, which in turn drives the seventh gear 37 to rotate, causing the rotating plate 39 to rotate. The outer wall of the sliding column 312 slides against the inner wall of the first slide groove 310. Through the rotation of the rotating plate 39, the sliding column 312 slides within the first slide groove 310, thereby causing the moving plate 313 to make a precise translational movement within the second slide groove 311. This allows the clamping plate 314, which is fixedly installed at the bottom of the moving plate 313, to retract smoothly, thereby causing the side wall of the clamping plate 314 to engage with the... After the flange sidewalls are in close contact, the third motor 32, which is fixedly installed at the top of the inner side of the positioning box 31, starts to run. The output end of the third motor 32 drives the fifth gear 33 to rotate. The fifth gear 33 meshes with the outer sidewall of the cover plate 38, causing the cover plate 38 to rotate, thereby causing the clamping plate 314 and the part to rotate, so that all the protrusions 320 are aligned with the holes on the flange sidewalls, until all the signal sensors 318 accurately sense that the protrusions 320 are not inside the positioning groove 317, thus determining that the part is accurately positioned.

[0023] In this embodiment, the guiding mechanism 2 includes a second motor 21 disposed on the side wall of the support plate 13. A first threaded rod 22 is disposed at the output end of the second motor 21. The other end of the first threaded rod 22 is rotatably connected to the inner side wall of the support plate 13. A guide box 23 is rotatably connected to the outer side wall of the first threaded rod 22. The bottom end of the guide box 23 is slidably connected to the outer side wall of the slide bar 112. A limit block 24 is disposed on the inner side wall of the guide box 23. Two guide grooves 214 are formed on the inner side wall of the guide box 23. A second threaded rod 217 is rotatably connected to the inner side wall of the guide grooves 214. A guide block 216 is rotatably connected to the outer side wall of the second threaded rod 217. A fourth gear 213 is rotatably connected to one side wall of the guide block 216. A second rack 215 is disposed at the bottom end of the inner side wall of the guide grooves 214. The fourth gear 213 and the second rack 215 are connected to each other. The outer walls of the two gears 215 mesh with each other. The fourth gear 213 has a rotating block 212 rotatably connected to one side wall. The bottom ends of the two rotating blocks 212 are provided with the same flip plate 211. The guide mechanism 2 also includes two first racks 26 provided on the top side wall of the support plate 13. One end of the second threaded rod 217 passes through the guide box 23 and is provided with a second bevel gear 210. The guide box 23 has two connecting plates 25 on one side wall. The top side wall of the connecting plate 25 is rotatably connected to a first bevel gear 28. The outer wall of the first bevel gear 28 meshes with the outer wall of the second bevel gear 210. The inner side wall of the connecting plate 25 is rotatably connected to a third gear 27. The outer wall of the third gear 27 is connected to the outer wall of the first bevel gear 28 by a second transmission chain 29. The outer wall of the third gear 27 meshes with the side wall of the first rack 26.

[0024] Specifically, the second motor 21 in the guide mechanism 2 is activated, driving the first threaded rod 22 to rotate at a constant speed. This causes the guide box 23 to slide precisely horizontally downwards along the two slide bars 112 at the top of the support plate 13 towards the positioning box 31. As the guide box 23 moves, the third gear 27 meshes with the first rack 26, causing the third gear 27 to rotate. This, in turn, drives the first bevel gear 28 to rotate via the second transmission chain 29. The first bevel gear 28 meshes with the second bevel gear 210, causing the second threaded rod 217 to rotate. This drives the guide block 216 to move along the guide groove 214 towards the part. As the guide block 216 moves, the fourth gear 213 meshes with the second rack 215, causing the fourth gear 213 to synchronously drive the rotating block 212 to rotate. This causes the flipping plate 211 to flip ninety degrees, making it vertical. This allows the flipping plate 211 to contact the side wall of the part and continue to push the other side wall of the part to contact the limiting block 24.

[0025] In this embodiment, a first motor 14 is provided on one side wall of the support plate 13. A transmission rod 15 is provided at each of the two output ends of the first motor 14. A first gear 16 is provided at one end of each of the two transmission rods 15. A second gear 18 is rotatably connected to both sides of the support plate 13. A first transmission chain 17 is connected to the outer side wall of the first gear 16 and the second gear 18. The same lifting platform 113 is slidably connected to the outer side wall of the four support columns 12. A first U-shaped rack 19 is provided on both sides of the lifting platform 113. The inner side wall of the first U-shaped rack 19 meshes with the outer side wall of the second gear 18. A second U-shaped rack 110 is provided on both sides of the positioning box 31. The inner side wall of the second U-shaped rack 110 meshes with the outer side wall of the second gear 18. An operating table 111 is provided at the top of the lifting platform 113.

[0026] Specifically, the first motor 14 installed on the side wall of the support plate 13 is started. When the first motor 14 is running, it drives the transmission rod 15, the first gear 16, and the first transmission chain 17 to rotate synchronously, which in turn drives the second gear 18 to rotate. Under the drive of the second gear 18, the lifting platform 113 and the positioning box 31 are driven to move synchronously and smoothly and slowly relative to each other along the four support columns 12 until the positioning box 31 moves to the appropriate height directly above the thin-walled part to be clamped.

[0027] It should be noted that this invention is a quick clamping device for preventing deformation of thin-walled parts. The user first places the base plate 1 on the machining station as the basic support structure for the entire device. The tops of the four support columns 12 are connected to the support plate 13, which provides a flat installation and movement reference for subsequent guiding and clamping operations. The operator places the atomizing disc part to be processed upside down on the top of the guide box 23, so that the bottom end of the flange at the top of the atomizing disc contacts the top of the guide box 23. Then, the second motor 21 in the guiding mechanism 2 is started, driving the first threaded rod 22 to rotate at a uniform speed, causing the guide box 23 to slide precisely horizontally downwards along the two sliding strips 112 at the top of the support plate 13 towards the positioning box 31. Simultaneously, the third gear 27... The third gear 27 rotates by meshing with the first rack 26, and drives the first bevel gear 28 to rotate via the second transmission chain 29. The first bevel gear 28 meshes with the second bevel gear 210, causing the second threaded rod 217 to rotate. This drives the guide block 216 to move along the guide groove 214 toward the part. While the guide block 216 moves, the fourth gear 213 meshes with the second rack 215, causing the fourth gear 213 to synchronously drive the rotating block 212 to rotate. This causes the flipping plate 211 to flip 90 degrees, making it vertical. This allows the flipping plate 211 to contact the side wall of the part and continue to push the other side wall of the part to contact the limiting block 24, thus preventing the part from shifting or slipping during transportation and ensuring accurate placement of the part. After the part is placed,

[0028] After the part is delivered to its position, the first motor 14 mounted on the side wall of the support plate 13 is started. When the first motor 14 is running, it drives the transmission rod 15, the first gear 16, and the first transmission chain 17 to rotate synchronously, which in turn drives the second gear 18 to rotate. Driven by the second gear 18, the lifting platform 113 and the positioning box 31 move synchronously and smoothly and slowly relative to each other along the four support columns 12 until the positioning box 31 moves to the appropriate height directly above the thin-walled part to be clamped. At this time, the first motor 14 stops running. At this time, the bottom end of the positioning plate 316 contacts the top end of the part flange. If at this time, the protrusion 320 does not align with the hole on the side wall of the flange. Alignment is achieved, and the protrusion 320 overcomes the force of the elastic component 319 and is pressed into the positioning groove 317. The signal sensor 318 accurately senses the contact state between the protrusion 320 and the flange sidewall in real time and feeds back a signal, thereby determining that the part is not positioned correctly. Subsequently, the fourth motor 35 is started to drive the sixth gear 36 to rotate, which in turn drives the seventh gear 37 to rotate, and drives the rotating plate 39 to rotate. The outer sidewall of the sliding column 312 slides against the inner sidewall of the first slide groove 310. Through the rotation of the rotating plate 39, the sliding column 312 slides in the first slide groove 310, thereby driving the moving plate 313 in the second slide groove 310. A precise translational movement is performed within the positioning box 313, causing the clamping plate 314, which is fixedly mounted at the bottom of the moving plate 313, to retract smoothly. This ensures that the sidewall of the clamping plate 314 makes tight contact with the sidewall of the flange. Subsequently, the third motor 32, fixedly mounted at the top of the inner side of the positioning box 31, starts running. The output end of the third motor 32 drives the fifth gear 33 to rotate. The fifth gear 33 meshes with the outer wall of the cover plate 38, causing the cover plate 38 to rotate. This, in turn, causes the clamping plate 314 and the part to rotate, aligning all the protrusions 320 with the holes on the sidewall of the flange, until all the signal sensors 318 accurately detect that the protrusions 320 are not inside the positioning groove 317. This ensures the accurate placement of the parts. Subsequently, the parts are processed by the machining mechanism on the operating table 111. Furthermore, by inverting the parts, it prevents debris from entering the interior of the atomizing disc during the machining of the multiple oblique holes, thus avoiding blockage and quality issues. After all the machining processes of the thin-walled parts are completed, each mechanism operates in reverse according to the aforementioned transmission path. The entire process requires no manual realignment, adjustment, or intervention, efficiently completing a complete anti-deformation fast clamping and machining process for thin-walled parts. This can meet the stable, precise, and efficient machining requirements for batch thin-walled conical parts.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
