Description

Technical Field

[0001] This application relates to the field of surface treatment tooling technology for annular parts, and in particular to a tooling device for removing burrs from the surface of large-diameter annular parts. Background Technology

[0002] In the field of machining, large-diameter ring-shaped parts (such as bearing rings, gear rings, flanges, etc.) are key basic components widely used in high-end equipment such as aerospace, wind power generation, and shipbuilding. After machining such workpieces through processes such as turning and milling, burrs inevitably form on their surfaces, edges, and openings. These burrs directly affect the assembly accuracy, service life, and operational safety of the parts. Therefore, efficient and high-quality burr removal is a crucial step in ensuring the final quality of ring-shaped parts. With the continuous improvement of precision and efficiency requirements in the manufacturing industry, the demand for automated and high-precision deburring tooling is increasing, and its design level directly determines the stability of the deburring process and the product yield.

[0003] Currently, the conventional clamping methods for grinding and deburring large-diameter ring-shaped parts mainly include the following: First, using a three-jaw or four-jaw chuck to clamp the workpiece from its outer diameter. The advantage of this method is its large clamping force and relatively stable clamping. However, the disadvantage is that for thin-walled ring-shaped parts, the radial clamping force can easily cause elastic or even plastic deformation of the workpiece. After machining, releasing the chuck will cause the workpiece to spring back, resulting in loss of precision on the machined surface. Furthermore, clamping the outer diameter can obstruct part of the surface to be machined, requiring secondary clamping and reducing machining efficiency. Second, using an electromagnetic chuck or permanent magnet chuck to adhere and fix the workpiece from its end face. This method is suitable for magnetic materials and can avoid radial clamping force. However, its disadvantage is that it cannot be used for non-magnetic materials such as stainless steel and aluminum alloys. Also, the fixed chuck layout limits the support points for large-diameter ring-shaped parts, potentially causing the suspended part of the workpiece to vibrate under the grinding force, affecting the grinding quality. Third, using pressure plate bolts to clamp the workpiece through through holes or pre-drilled process holes. This method is relatively reliable, but its disadvantages are that it requires the workpiece to have a structure that can be clamped, which places requirements on the workpiece design, and the area near the clamping point will become a grinding dead zone, making it impossible to remove all the burrs on the surface at once.

[0004] Existing clamping methods generally suffer from defects such as easy extrusion deformation of thin-walled ring parts, limited applicable materials, existence of processing dead corners, or insufficient clamping stability. It is difficult to achieve comprehensive, efficient, and stable grinding and deburring operations on large-diameter ring parts while ensuring that the workpiece does not undergo clamping deformation.

[0005] Therefore, this application provides a tooling device for removing burrs from the surface of a large-diameter annular part. Summary of the Invention

[0006] The purpose of this application is to solve at least one technical problem raised in the background art.

[0007] This application provides a tooling device for removing burrs from the surface of a large-diameter annular part, including a tooling support base, a circumferential inner support mechanism, a vertical positioning mechanism, and a grinding mechanism;

[0008] The tooling support includes a circular base, with a large-diameter annular main body placed on the upper surface of the circular base;

[0009] The circumferential inner support mechanism includes four strip-shaped grooves arranged in a circumferential array on the upper surface of a circular base, and L-shaped sliding plates respectively slidably disposed on the inner walls of the four strip-shaped grooves. The ends of the L-shaped sliding plates are fixed with arc-shaped rubber pads, and the outer surface of the circular base is provided with a drive motor for driving the four L-shaped sliding plates to move outward or inward simultaneously.

[0010] The vertical positioning mechanism includes two vertical plates symmetrically fixed on the upper surface of the circular base, and a transverse pressure plate slidably disposed on the opposite side of the two vertical plates;

[0011] The polishing mechanism includes a rotating ring that is rotatably mounted on the upper surface of a circular base via a circular slide rail. A polishing motor is mounted on the top of the rotating ring, and a polishing disc is fixedly mounted on the output end of the polishing motor.

[0012] Preferably, the upper surface of the circular base has three mounting holes arranged in a circumferential array, and the inner walls of the three mounting holes are provided with hexagonal socket head cap screws.

[0013] By adopting the above technical solution, it is easy to install the circular base on the ground or on the machine tool workbench using hexagon socket head cap screws.

[0014] Preferably, the circular base has a cylindrical cavity inside, and the inner top and bottom walls of the cylindrical cavity are rotatably provided with vertical shafts. A first bevel gear is fixedly provided on the surface of the vertical shaft. Two symmetrical horizontal shafts are rotatably provided on the inner wall of the cylindrical cavity. One end of one horizontal shaft extends to the outer surface of the circular base. The output end of the drive motor is fixedly connected to the end of the horizontal shaft. The other end of the horizontal shaft fixedly connected to the output end of the drive motor is fixedly provided with a second bevel gear. The second bevel gear meshes with the first bevel gear.

[0015] By adopting the above technical solution, the rotation of the drive motor can drive a horizontal shaft to rotate, which in turn drives the second bevel gear to rotate. The rotation of the second bevel gear can drive the first bevel gear and the vertical shaft to rotate automatically.

[0016] Preferably, the inner walls of the four strip grooves are rotatably provided with transverse threaded columns, and the surfaces of the four L-shaped slides are provided with transverse threaded holes that are threaded to the outer surfaces of the four transverse threaded columns respectively. One end of each of the four transverse threaded columns extends into the interior of the cylindrical cavity and is fixedly provided with a driven bevel gear. The surface of the vertical shaft is fixedly provided with a bevel gear disk, and the four driven bevel gears mesh with the bevel gear disk.

[0017] By adopting the above technical solution, the bevel gear disk can be driven to rotate during the rotation of the vertical shaft. The rotation of the bevel gear disk drives the four driven bevel gears to rotate automatically, thereby driving the four transverse threaded columns to rotate synchronously. The rotation of the four transverse threaded columns can drive the four L-shaped sliding plates to move outward simultaneously, providing internal support for the large-diameter ring-shaped main body.

[0018] Preferably, rectangular grooves are provided on the opposite surfaces of the two vertical plates, and the two ends of the horizontal pressure plate are slidably connected to the inner walls of the two rectangular grooves respectively. Vertical threaded columns are rotatably provided on the inner walls of the rectangular grooves, and vertical threaded holes are provided on the two end surfaces of the horizontal pressure plate respectively, which are threadedly connected to the outer surfaces of the two vertical threaded columns.

[0019] By adopting the above technical solution, the rotation of the vertical threaded column can drive the horizontal pressure plate to move automatically downward.

[0020] Preferably, the circular base has two connecting cavities corresponding to the two vertical plates. The bottom ends of the two vertical threaded columns extend into the two connecting cavities and are each fixed with a third bevel gear. The two horizontal shafts pass through the two connecting cavities, and the surfaces of the two horizontal shafts are each fixed with a fourth bevel gear that meshes with the two third bevel gears. The end of the other horizontal shaft is fixed with a fifth bevel gear that meshes with the first bevel gear.

[0021] By adopting the above technical solution, the first bevel gear can drive the fifth bevel gear to rotate when it rotates, thereby driving the two horizontal shafts to rotate synchronously. The rotation of the horizontal shafts drives the fourth bevel gear to rotate, thereby driving the third bevel gear and the vertical threaded column to rotate, thus achieving synchronous rotation of the two vertical threaded columns.

[0022] Preferably, a buffer plate is provided on the lower surface of the transverse pressure plate, and a plurality of buffer springs are fixed at equal intervals between the upper surface of the buffer plate and the lower surface of the transverse pressure plate. Limiting rods are fixed on the upper surfaces of both ends of the buffer plate, and sliding holes that are slidably connected to the surfaces of the limiting rods are opened on the lower surface of the transverse pressure plate.

[0023] By adopting the above technical solution, when the transverse pressure plate presses down on the main body of the large-diameter ring component, the top of the main body of the large-diameter ring component can be effectively pressed down and buffered under the action of the buffer plate and the buffer spring.

[0024] Preferably, a vertical frame is fixedly provided on the surface of the rotating ring, a horizontal frame is slidably provided on the inner wall of the vertical frame, the grinding motor is slidably provided on the inner wall of the horizontal frame, a first hydraulic rod is embedded in the inner top wall of the vertical frame, the telescopic end of the first hydraulic rod is fixedly connected to the upper surface of the horizontal frame, a second hydraulic rod is embedded in the end of the horizontal frame, and the telescopic end of the second hydraulic rod is fixedly connected to the surface of the grinding motor.

[0025] By adopting the above technical solution, the height of the grinding motor and grinding disc can be adjusted by extending and retracting the first hydraulic rod, and the lateral position of the grinding motor and grinding disc can be adjusted by extending and retracting the second hydraulic rod.

[0026] Preferably, a T-shaped mounting plate is fixed to the surface of one of the vertical plates, a rotary motor is fixed to the surface of the T-shaped mounting plate, a gear disk is fixed to the output end of the rotary motor, and an external gear ring that meshes with the gear disk is fixed to the outer surface of the rotating ring.

[0027] By adopting the above technical solution, the rotation of the rotary motor can drive the gear disc to rotate, thereby driving the rotating ring to rotate automatically under the action of the external gear ring.

[0028] Preferably, the upper surface of the circular base is further provided with a waste collection mechanism. The waste collection mechanism includes an annular suction box fixed to the upper surface of the circular base. The inner ring surface of the annular suction box is provided with a plurality of suction hoods arranged in a circumferential array. The waste collection mechanism also includes a suction fan fixed to the outer ring surface of the annular suction box. The suction end of the suction fan extends into the interior of the annular suction box, and the air outlet end of the suction fan is fixed with a dust collection bag by wire.

[0029] By adopting the above technical solution, during the grinding process, the suction fan can be activated, and the annular suction box can be used to suck up and absorb the debris and dust generated during grinding through several suction hoods, and then collect them through a dust collection bag.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. The tooling device for deburring the surface of a large-diameter annular part as described in this application, by setting a circumferential inner support mechanism and a vertical positioning mechanism, can place the large-diameter annular part body at the center position of a circular base when deburring the large-diameter annular part body. Then, the drive motor is started, and the rotation of the drive motor drives a horizontal shaft to rotate. The rotation of the horizontal shaft drives a second bevel gear to rotate, thereby driving the first bevel gear and the vertical shaft to rotate automatically. The rotation of the vertical shaft drives a bevel gear disk to rotate, and the rotation of the bevel gear disk drives four driven bevel gears and four transverse threaded columns to rotate simultaneously, thereby driving four L-shaped sliding plates to move outward simultaneously, so that the four L-shaped sliding plates effectively deburr the inner ring surface of the large-diameter annular part body. The internal support positioning, while the first bevel gear rotates, can drive the fifth bevel gear and another horizontal shaft to rotate, thereby driving the two horizontal shafts to rotate synchronously. The rotation of the two horizontal shafts drives the two fourth bevel gears to rotate, thereby driving the two third bevel gears and two vertical threaded columns to rotate synchronously. The synchronous rotation of the two vertical threaded columns causes the horizontal pressure plate to move automatically downward, realizing the vertical effective clamping and fixing of the large-diameter ring body, thus effectively ensuring the stability of the large-diameter ring body during grinding. Compared with the existing technology, this technical solution adopts an internal support method, avoiding the squeezing deformation of the thin-walled ring body caused by clamping from the outside of the workpiece, and ensuring the processing accuracy and shape tolerance of the workpiece.

[0032] 2. The tooling device for removing burrs from the surface of a large-diameter annular part as described in this application, by setting a grinding mechanism, can start a grinding motor and a rotary motor during grinding. The grinding motor drives the grinding disc to grind the outer ring surface of the large-diameter annular part, while the rotary motor drives the gear disc to rotate, thereby driving the rotating ring to rotate under the action of the outer gear ring. This, in turn, drives the grinding motor and the grinding disc to perform circumferential motion around the large-diameter annular part, achieving the purpose of uniform grinding. Thus, the device can perform deburring and grinding with full-process start-up, reducing the time consumption of manual grinding and the pressure of subsequent inspection.

[0051] Please refer to the following carefully. Figures 1 to 10 A tooling device for removing burrs from the surface of a large-diameter annular part includes a tooling support 100, a circumferential inner support mechanism 200, a vertical positioning mechanism 300, and a grinding mechanism 400. The tooling support 100 includes a circular base 101, on which the large-diameter annular part body 600 is placed. The circumferential inner support mechanism 200 includes four strip-shaped grooves arranged in a circumferential array on the upper surface of the circular base 101, and L-shaped sliding plates 201 respectively slidably disposed on the inner walls of the four strip-shaped grooves. An arc-shaped rubber pad 20 is fixed at the end of the L-shaped sliding plate 201. 2. The outer surface of the circular base 101 is provided with a drive motor 203 for driving four L-shaped slide plates 201 to move outward or inward simultaneously; the vertical positioning mechanism 300 includes two vertical plates 301 symmetrically fixed on the upper surface of the circular base 101, and a transverse pressure plate 302 slidably disposed on the opposite side of the two vertical plates 301; the grinding mechanism 400 includes a rotating ring 401 rotatably disposed on the upper surface of the circular base 101 via a circular slide rail, a grinding motor 402 is disposed on the top of the rotating ring 401, and a grinding disc 403 is fixedly disposed at the output end of the grinding motor 402.

[0052] Please refer to this carefully. Figure 2 , Figure 3 The upper surface of the circular base 101 has three mounting holes arranged in a circumferential array, and the inner walls of the three mounting holes are provided with hexagonal socket bolts 102.

[0053] Specifically, it allows the circular base 101 to be easily installed on the ground or on a machine tool workbench using hex socket head cap screws 102.

[0054] Please refer to this carefully. Figure 9 , Figure 10 The circular base 101 has a cylindrical cavity inside, and a vertical shaft 204 is rotatably provided on the inner top and bottom walls of the cylindrical cavity. A first bevel gear 205 is fixed on the surface of the vertical shaft 204. Two symmetrical horizontal shafts 206 are rotatably provided on the inner wall of the cylindrical cavity. One end of one horizontal shaft 206 extends to the outer surface of the circular base 101. The output end of the drive motor 203 is fixedly connected to the end of the horizontal shaft 206. A second bevel gear 207 is fixedly provided on the other end of the horizontal shaft 206, which is fixedly connected to the output end of the drive motor 203. The second bevel gear 207 meshes with the first bevel gear 205.

[0055] Specifically, the rotation of the drive motor 203 can drive a horizontal shaft 206 to rotate, which in turn drives the second bevel gear 207 to rotate. The rotation of the second bevel gear 207 can drive the first bevel gear 205 and the vertical shaft 204 to rotate automatically.

[0056] Please refer to this carefully. Figure 4 , Figure 9The inner walls of the four strip grooves are rotatably provided with transverse threaded posts 208, and the surfaces of the four L-shaped slide plates 201 are provided with transverse threaded holes that are threaded to the outer surfaces of the four transverse threaded posts 208 respectively. One end of each of the four transverse threaded posts 208 extends into the interior of the cylindrical cavity and is fixedly provided with a driven bevel gear 209. The surface of the vertical shaft 204 is fixedly provided with a bevel gear disk 2010, and the four driven bevel gears 209 mesh with the bevel gear disk 2010.

[0057] Specifically, the vertical shaft 204 can rotate to drive the bevel gear disk 2010 to rotate. The rotation of the bevel gear disk 2010 drives the four driven bevel gears 209 to rotate automatically, thereby driving the four transverse threaded columns 208 to rotate synchronously. The rotation of the four transverse threaded columns 208 can drive the four L-shaped slide plates 201 to move outward simultaneously, providing internal support for the large-diameter annular body 600.

[0058] Please refer to this carefully. Figure 7 , Figure 8 The two vertical plates 301 have rectangular grooves on their opposite sides. The two ends of the horizontal pressure plate 302 are slidably connected to the inner walls of the two rectangular grooves. The inner walls of the rectangular grooves are rotatably provided with vertical threaded posts 303. The two ends of the horizontal pressure plate 302 are provided with vertical threaded holes that are threadedly connected to the outer surfaces of the two vertical threaded posts 303.

[0059] Specifically, the rotation of the vertical threaded column 303 can drive the horizontal pressure plate 302 to move automatically downward.

[0060] Please refer to this carefully. Figure 8 , Figure 9 The circular base 101 has two connecting cavities corresponding to the two vertical plates 301. The bottom ends of the two vertical threaded columns 303 extend into the two connecting cavities and are each fixed with a third bevel gear 304. The two horizontal shafts 206 pass through the two connecting cavities respectively, and the surfaces of the two horizontal shafts 206 are each fixed with a fourth bevel gear 305 that meshes with the two third bevel gears 304. The end of the other horizontal shaft 206 is fixed with a fifth bevel gear 306 that meshes with the first bevel gear 205.

[0061] Specifically, when the first bevel gear 205 rotates, it can drive the fifth bevel gear 306 to rotate, thereby driving the two horizontal shafts 206 to rotate synchronously. The rotation of the horizontal shafts 206 drives the fourth bevel gear 305 to rotate, thereby driving the third bevel gear 304 and the vertical threaded column 303 to rotate, thus enabling the two vertical threaded columns 303 to rotate synchronously.

[0062] Please refer to this carefully. Figure 3 , Figure 7A buffer plate 307 is provided on the lower surface of the transverse pressure plate 302. Several buffer springs 308 are fixed at equal intervals between the upper surface of the buffer plate 307 and the lower surface of the transverse pressure plate 302. Limiting rods 309 are fixed on the upper surfaces of both ends of the buffer plate 307, and sliding holes that are slidably connected to the surface of the limiting rods 309 are opened on the lower surface of the transverse pressure plate 302.

[0063] Specifically, when the transverse pressure plate 302 presses down on the large-diameter annular body 600, the top of the large-diameter annular body 600 is effectively pressed down and buffered by the buffer plate 307 and the buffer spring 308.

[0064] In this invention, by setting up a circumferential inner support mechanism 200 and a vertical positioning mechanism 300, when deburring the large-diameter annular part body 600, the large-diameter annular part body 600 can be placed at the center of the circular base 101. Then, the drive motor 203 is started. The rotation of the drive motor 203 drives a horizontal shaft 206 to rotate. The rotation of the horizontal shaft 206 drives a second bevel gear 207 to rotate, thereby causing the first bevel gear 205 and the vertical shaft 204 to rotate automatically. The rotation of the vertical shaft 204 drives the bevel gear disk 2010 to rotate. The rotation of the bevel gear disk 2010 drives four driven bevel gears 209 and four transverse threaded columns 208 to rotate simultaneously, thereby causing four L-shaped sliding plates 201 to move outward simultaneously, so that the four L-shaped sliding plates 201 move against the inner ring surface of the large-diameter annular part body 600. The device features effective internal support positioning. Simultaneously, during the rotation of the first bevel gear 205, it drives the fifth bevel gear 306 and another horizontal shaft 206 to rotate, thereby causing the two horizontal shafts 206 to rotate synchronously. The rotation of the two horizontal shafts 206 drives the two fourth bevel gears 305 to rotate, which in turn drives the two third bevel gears 304 and two vertical threaded columns 303 to rotate synchronously. The synchronous rotation of the two vertical threaded columns 303 causes the horizontal pressure plate 302 to move automatically downwards, achieving effective vertical clamping and fixing of the large-diameter annular body 600. This effectively ensures the stability of the large-diameter annular body 600 during grinding. Compared with existing technologies, this technical solution uses an internal support method, avoiding the squeezing deformation of the thin-walled annular part caused by clamping from the outside of the workpiece, thus ensuring the processing accuracy and shape tolerance of the workpiece.

A horizontal frame 405 is slidably mounted on the inner wall of the vertical frame 404. The grinding motor 402 is slidably mounted on the inner wall of the horizontal frame 405. A first hydraulic rod 406 is embedded in the inner top wall of the vertical frame 404. The telescopic end of the first hydraulic rod 406 is fixedly connected to the upper surface of the horizontal frame 405. A second hydraulic rod 407 is embedded in the end of the horizontal frame 405. The telescopic end of the second hydraulic rod 407 is fixedly connected to the surface of the grinding motor 402.

[0066] Specifically, the height of the grinding motor 402 and the grinding disc 403 can be adjusted by extending and retracting the first hydraulic rod 406, and the lateral position of the grinding motor 402 and the grinding disc 403 can be adjusted by extending and retracting the second hydraulic rod 407.

An external gear ring 4010 that meshes with the gear disk 409 is fixed on the outer surface of the rotating ring 401.

[0068] Specifically, the rotation of the rotary motor 408 can drive the gear disk 409 to rotate, thereby driving the rotating ring 401 to rotate automatically under the action of the outer gear ring 4010.

[0069] Please refer to this carefully. Figure 2 , Figure 3 The upper surface of the circular base 101 is also provided with a waste collection mechanism 500. The waste collection mechanism 500 includes an annular suction box 501 fixed on the upper surface of the circular base 101. The inner ring surface of the annular suction box 501 is provided with a number of suction hoods 502 arranged in a circular array. The waste collection mechanism 500 also includes a suction fan 503 fixed on the outer ring surface of the annular suction box 501. The suction end of the suction fan 503 extends into the interior of the annular suction box 501. The exhaust end of the suction fan 503 is fixed with a dust collection bag 504 by wire.

[0070] Specifically, during the polishing process, the suction fan 503 can be activated, so that the annular suction box 501 can suck up and absorb the debris and dust generated during polishing through several suction hoods 502, and collect them through the dust collection bag 504.

[0071] In this invention, a grinding mechanism 400 is provided. During grinding, a grinding motor 402 and a rotary motor 408 are activated. The grinding motor 402 drives the grinding disc 403 to grind the outer ring surface of the large-diameter annular part body 600. At the same time, the rotary motor 408 drives the gear disc 409 to rotate, thereby driving the rotating ring 401 to rotate under the action of the outer gear ring 4010. This, in turn, drives the grinding motor 402 and the grinding disc 403 to perform circumferential motion around the large-diameter annular part body 600, achieving the purpose of uniform grinding. This allows the device to perform deburring and grinding with full-process activation, reducing the time spent on manual grinding and the pressure of subsequent inspection.
