Description

Technical Field

[0001] This invention relates to the field of grinding wheel dressing technology, and in particular to a superhard abrasive forming device and processing method based on laser beam dressing. Background Technology

[0002] Superhard abrasives are materials with extremely high hardness and wear resistance, commonly used in the manufacture of grinding wheels and cutting tools. Grinding wheels also require regular dressing to ensure optimal grinding and cutting performance. Common methods for dressing superhard abrasive grinding wheels include mechanical, laser, electrical discharge machining (EDM), electrolytic machining, and composite machining methods. Among these, laser-based dressing offers advantages such as high dressing accuracy, non-contact processing reducing wear and damage during machining, and producing less debris, making it more environmentally friendly.

[0003] The existing Chinese invention patent with publication number CN114523418B provides a laser-assisted large depth-of-cut dressing device and method for forming grinding wheels. This device includes a work platform, a grinding wheel, a motor, an X-axis manual slide, a Y-axis manual slide, a laser galvanometer head, and a Z-axis electric slide. Its advantages include high grinding wheel material removal efficiency and ease of automation; during large depth-of-cut dressing, the uniformity of binder material removal is good, and the abrasive grain exit height is highly controllable. However, its disadvantages include the need for manual feeding and unloading of materials, and the small amount of debris generated during dressing falling onto the worktable, causing a messy and unsanitary situation.

Detailed Implementation

[0037] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0039] Example: Figures 1-4 As shown, a dressing motor 102 is fixedly connected to the frame 101, and a clamping tooth 105 is fixedly connected to the dressing motor 102. Two cylinders 106 are fixedly installed on the frame 101, and laser dressers 104 are fixedly connected to the cylinders 106. The two laser dressers 104 are symmetrically arranged about the dressing motor 102. A feeding component 2 is provided on the frame 101 for transporting the grinding wheel 6. A flipping component 3 is provided on the frame 101 for flipping the grinding wheel 6. An expansion component 4 is provided on the flipping component 3 for clamping the grinding wheel 6. A displacement component 5 is provided on the frame 101 for moving the flipping component 3. The displacement of the laser dresser 104 is adjusted by extending and retracting the cylinders 106, and the laser dresser 104 dresses the grinding wheel 6.

[0040] like Figures 4-5As shown, the feeding component 2 includes a feeding bracket 212, which is fixedly connected to the frame 101. A feeding cylinder 201, a feeding frame 202, and a feeding motor 206 are fixedly connected to the feeding bracket 212. A pulley 205 is rotatably connected to the feeding bracket 212. A belt II 208 is fitted between the feeding motor 206 and the pulley 205. Multiple elastic push blocks 209 are provided on the belt II 208. The feeding cylinder 201 is fixedly connected to the feeding frame 202. One end of the feed cylinder 201 is threaded to a baffle 210, and a baffle spring 211 is fixedly connected to the baffle 210. Multiple baffles 203 are fixedly connected to the feed cylinder 201, and multiple baffles 203 are rotatably connected to the feed frame 202. A torsion spring is provided between the baffles 203 and the feed frame 202. A limiting hole 204 is provided on the feed frame 202. The radius of the limiting hole 204 is greater than the outer diameter of the expansion shaft 403, and the radius of the limiting hole 204 is smaller than the outer diameter of the synchronization ring 407. By rotating the baffle 210 to detach it from the feeding cylinder 201, a batch of grinding wheels 6 are placed in the feeding cylinder 201. Then, the baffle 210 is installed on the feeding cylinder 201. At this time, the baffle spring 211 compresses the grinding wheel 6, so that the grinding wheel 6 is always pressed against the stop bar 203 on the feeding cylinder 201. By starting the feeding motor 206, the belt II 208 rotates. At this time, the elastic push block 209 will push a grinding wheel 6 to the feeding frame 202. Because the stop bar 203 limits the movement, the grinding wheel 6 will not move abnormally. At the same time, the pulley 205 will also drive the drive shaft 501 to rotate through the belt I 207. When there is a grinding wheel 6 at the feeding frame 202, the grinding wheel 6 at the feeding cylinder 201 cannot be pushed by the elastic push block 209. The elastic push block 209 will also be slightly deformed due to the compression of the grinding wheel 6, and then pass over the grinding wheel 6.

[0041] like Figures 7-8As shown, the tilting component 3 includes a chip collection frame 301, which is slidably connected to the frame 101. Inclined block grooves 311 are respectively provided on both sides of the chip collection frame 301. A drive shaft 309 is rotatably connected to the chip collection frame 301. A fixed shaft 416 is fixedly connected to the drive shaft 309. Tilting linkage assemblies are respectively provided on both sides of the drive shaft 309. The tilting linkage assembly includes a crank 305, which is fixedly connected to one end of the drive shaft 309. A connecting rod I 306 is rotatably connected to the handle 305, and a connecting rod II 310 is rotatably connected to the connecting rod I 306. The connecting rod II 310 is rotatably connected to the tilting slider 312. Vertical and arc-shaped grooves are respectively provided on both sides of the chip collection frame 301, with the arc-shaped groove communicating with the vertical groove. The tilting slider 312 slides on the vertical groove. The connecting rod II 310 engages with both the vertical and arc-shaped grooves. Inclined springs 314 are slidably connected to both sides of the chip collection frame 301. A wedge block 313 is fixedly connected to a block spring 314. The wedge block 313 is slidably connected to a wedge block groove 311. The wedge block 313 cooperates with a connecting rod II 310 on the same side. A movable baffle 315 is fixedly connected to the two connecting rods II 310. A tilting motor 303 is fixedly connected to one side of the chip collection frame 301. A tilting gear I 302 is fixedly connected to the tilting motor 303. A tilting gear II 304 is fixedly connected to the crank 305 on the same side. The tilting gear I 302 and the tilting... Rotary gear II 304 meshes; chip collection plate 308 and drive synchronization plate 317 are fixedly connected to chip collection frame 301, stirring plate 307 is rotatably connected to chip collection frame 301, bevel gear I 316 is fixedly connected to one end of stirring plate 307, feeding plate 103 is rotatably connected to chip collection frame 301, torsion spring is provided between feeding plate 103 and chip collection frame 301, multiple filter holes are provided on one side of feeding plate 103, and feeding plate 103 cooperates with movable baffle 315.When the reversing motor 303 starts, the reversing gear I 302 drives the reversing gear II 304 to rotate. The reversing gear II 304 causes the crank 305 to rotate, and simultaneously, through the drive shaft 309, the crank 305 on the other side rotates synchronously. When the crank 305 rotates, it pulls the connecting rod I 306. The movement of the connecting rod I 306 causes the connecting rod II 310 to slide upward. At the same time, the reversing slider 312 moves upward, and the inclined block spring 314 slowly extends. When the end of the connecting rod II 310 near the inclined block 313 moves from the lowest point to the junction of the arc-shaped slide groove and the vertical slide groove, the drive shaft 309 rotates 90 degrees. During this process, the movable baffle 315 moves vertically upward in a horizontal state. As the reversing motor 303 continues to rotate, due to the support force provided by the inclined surface of the inclined block 313, the end of the connecting rod II 310 near the inclined block 313 slides from the vertical slide groove to the arc-shaped slide groove. At this time, the drive shaft 309 is still rotating. Meanwhile, the movable baffle 315 begins to deflect around the flip slider 312 as the center. During this process, the inclined block 313 slides on the inclined block groove 311, ensuring that the inclined block 313 can always support the connecting rod II 310. At the same time, the inclined block spring 314 also slides synchronously on the chip collection frame 301 until the drive shaft 309 rotates another 90 degrees. At this time, the movable baffle 315 also deflects to the vertical position. The entire process involves the drive shaft 309 rotating 180 degrees. 315, the chip collection frame 301, and the chip collection plate 308 together form an unsealed chip collection box; during the process of the movable baffle 315 deflecting from a horizontal state to a vertical state, the movable baffle 315 begins to slowly move away from the feed plate 103. After the feed plate 103 loses the support of the movable baffle 315, it begins to reset under the action of the torsion spring. At this time, the other side of the feed plate 103 overlaps with the chip collection frame 301, and the debris cannot fall out of the chip collection frame 301 through the feed plate 103.

[0042] like Figures 9-12As shown, the expansion component 4 includes an expansion shaft 403, which is rotatably connected to a fixed shaft 416. A synchronizing ring 407 is slidably connected to the expansion shaft 403. Multiple expansion units are provided on the expansion shaft 403. Each expansion unit includes an expansion telescopic rod I 411, an expansion telescopic rod II 412, an expansion telescopic rod III 414, and an expansion telescopic rod IV 415. The expansion telescopic rod I 411 is rotatably connected to the expansion slider I 409, which is slidably connected to the expansion shaft 403. The expansion telescopic rod I 411 and the expansion slider I 409 are connected by a torsion spring II 408. The expansion telescopic rod I 411 and the expansion telescopic rod II 412 are rotatably connected. II412 is rotatably connected to the expansion slider II410, which is slidably connected to the expansion shaft 403. The expansion telescopic rod III414 is rotatably connected to the expansion spring 413, which is rotatably connected to the expansion telescopic rod IV415. The expansion telescopic rod IV415 is rotatably connected to the expansion shaft 403, and the expansion telescopic rod IV415 is connected to the expansion shaft 403 via a torsion spring I404. Expansion springs 413 are provided on all expansion telescopic rods I411, II412, III414, and IV415. Expansion telescopic rod I411 and II412 are of the same length, and expansion telescopic rod III414 is rotatably connected to the expansion shaft 403. The retractable rod IV 415 has the same length, the expansion telescopic rod II 412 has a shorter length than the expansion telescopic rod III 414, the support plate I 401 is rotatably connected to the expansion telescopic rods I 411 and II 412, the support plate II 402 is rotatably connected to the expansion telescopic rods III 414 and IV 415, the expansion slider II 410 is slidably connected to the support plate II 402, and the synchronizing ring 407 is fixedly connected to multiple expansion sliders I 409; the expansion shaft 403 is provided with the same number of locking units as the expansion units; the locking unit includes a locking plate 405 and a pull rod 406, the pull rod 406 is rotatably connected to the expansion shaft 403, and the locking plate 405 is slidably connected to the expansion shaft 403. On shaft 403, locking plate 405 is fixedly connected to synchronous ring 407. Locking plate 405 is provided with locking groove unit I 4051, locking groove unit II 4052, locking groove unit III 4053, locking groove unit IV 4054, locking groove unit V 4055, and locking groove unit VI 4056. Locking groove unit I 4051, locking groove unit II 4052, locking groove unit III 4053, locking groove unit IV 4054, and locking groove unit V 4055 are connected end to end in sequence. Locking groove unit VI 4056 is connected to the junction of locking groove unit I 4051 and locking groove unit V 4055. Together they form a locking groove. Pull rod 406 slides on the locking groove.Initially, the axes of support plates I 401 and II 402 are not parallel to the axis of the expansion shaft 403, and one end of the pull rod 406 is on the locking slot unit VI 4056. When the grinding wheel 6 is placed in the clamping area and then the synchronizing ring 407 is pushed a certain distance, the synchronizing ring 407 causes all expansion sliders I 409 to slide on the expansion shaft 403, and the locking plate 405 slides on the expansion shaft 403. Expansion slider II 410 also begins to slide on the expansion shaft 403. At this time, torsion springs I 404 and II 408 begin to deform under force, and the pull rod 406 begins to slide into the locking slot unit VI 4056. On component I 4051, simultaneously due to the sliding of expansion sliders I 409 and II 410, the included angle between expansion telescopic rods I 411 and II 412 decreases, as does the included angle between expansion telescopic rods III 414 and IV 415. Therefore, support plates I 401 and II 402 also successively contact the inner diameter of the grinding wheel 6. When both support plates I 401 and II 402 are in contact with the inner diameter of the grinding wheel 6, they become parallel to the axis of the expansion shaft 403. Then, the synchronous ring 407 continues to be pushed. Because support plates I 401 and II 402... 01. Support plate II 402 can no longer expand, so the expansion spring 413 begins to be compressed, and the pull rod 406 also moves to the locking groove unit II 4052. Then, the thrust of the synchronizing ring 407 is released, and under the action of the expansion spring 413, the locking plate 405 begins to move away from the pull rod 406. At this time, the pull rod 406 moves to the locking groove unit III 4053, that is, the pull rod 406 will pull the locking plate 405, so that support plate I 401 and support plate II 402 support the grinding wheel 6; then, when the synchronizing ring 407 is pushed the same distance again, the pull rod 406 will move from the locking groove unit III 4052. 53 moves to the locking slot unit IV 4054. When the force of the synchronizing ring 407 is released again, the pull rod 406 will move from the locking slot unit IV 4054 to the locking slot unit V 4055, and then back to the locking slot unit VI 4056. At this time, the support plate I 401 and the support plate II 402 return to their initial state, and the clamped grinding wheel 6 will also lose the expansion support of the support plate I 401 and the support plate II 402. Since the axis of the support plate I 401 and the support plate II 402 is not parallel to the axis of the expansion shaft 403 at this time, the grinding wheel 6 will slide off the support plate I 401 and the support plate II 402.

[0043] like Figure 13As shown, the displacement component 5 includes a drive shaft 501 and a driven shaft 502. The driven shaft 502 is movably connected to the drive shaft 501. The drive shaft 501 is rotatably connected to the frame 101. A belt I 207 is sleeved between the drive shaft 501 and the pulley 205. A displacement gear I 503 is fixedly connected to the drive shaft 501. An elliptical groove 508 is provided on the drive shaft 501. The driven shaft 502 is movably connected to the frame 101. A displacement gear IV 506 is fixedly connected to the driven shaft 502. A slide rod 507 is fixedly connected to the upper part of the frame 101. The slide rod 507 slides on the elliptical groove 508. The driven shaft 502 is rotatably connected to the drive synchronous plate 317. A bevel gear II 509 is fixedly connected to the driven shaft 502. The bevel gear II 509 meshes with the bevel gear I 316. A displacement gear III 505 is rotatably connected to the frame 101. A displacement gear II 504 is fixedly connected to the displacement gear III 505. The displacement gear II 504 meshes with the displacement gear I 503. The displacement gear III 505 meshes with the displacement gear IV 506. When belt I207 drives the drive shaft 501 to rotate, displacement gear I503 will drive displacement gear II504 to rotate, and displacement gear III505 will also drive the driven shaft 502 to rotate through displacement gear IV506. When the driven shaft 502 rotates, it will drive bevel gear I316 to rotate slowly through bevel gear II509, flattening the debris accumulated at the bottom. By setting the number of teeth of displacement gears I503, II504, III505 and IV506, differential rotation between drive shaft 501 and driven shaft 502 can be achieved. Therefore, slide bar 507 will slide on elliptical groove 508. Due to the effect of elliptical groove 508, drive synchronization plate 317 will drive the chip collection frame 301 to slide back and forth as a whole.

[0044] Working principle: Open the baffle 210 to place a batch of grinding wheels 6 into the feeding cylinder 201, then close the baffle 210 and start the feeding motor 206 so that the elastic pusher 209 on the belt II 208 transports a piece of grinding wheel 6 from the feeding cylinder 201 to the feeding frame 202. At the same time, the rotation of the drive shaft 501 causes the drive synchronization plate 317 to drive the chip collection frame 301 to move. The sliding of the drive synchronization plate 317 driving the chip collection frame 301 is recorded as eight stages, with the same displacement in each stage. The first stage is: the chip collection frame 301 moves closer to the upper feeding cylinder 201. At this time, the flipping motor 303 is not started, and the expansion shaft 403 is in the position of... Approaching the feeding frame 202, and with the expanding shaft 403 and the limiting hole 204 coaxial, the expanding shaft 403, driven by the chip collecting frame 301, approaches and passes through the limiting hole 204. Simultaneously, the limiting hole 204 blocks the synchronizing ring 407, causing the support plates I 401 and II 402 to gradually expand until they completely support the inner diameter of the grinding wheel 6. At this point, the support plates I 401 and II 402 are coaxial with the expanding shaft 403, and the pull rod 406 slides onto the locking groove unit II 4052. Then, the chip collecting frame 301 begins its next... The second stage of displacement: At this time, the chip collecting frame 301 drives the expansion component 4 to move away from the feeding frame 202, the pull rod 406 moves to the locking groove unit Ⅲ 4053, the support plate Ⅰ 401 and support plate Ⅱ 402 still support the grinding wheel 6, and at the same time, the grinding wheel 6 moves synchronously over the stop bar 203, and the chip collecting frame 301 returns to the initial position of the first stage; then the chip collecting frame 301 begins the third stage of displacement: the chip collecting frame 301 continues to move away from the feeding frame 202, and at the same time the flipping motor 303 starts, at this time the movable baffle 315 begins to move vertically upward in a horizontal state, while the fixed shaft 416 is parallel to the movable baffle 315. The state is rotated to a state perpendicular to the movable baffle 315; then the chip collection frame 301 begins the fourth stage of displacement: the flipping motor 303 continues to rotate, the connecting rod II 310 begins to slide to the arc-shaped slide groove, the movable baffle 315 begins to deflect until the movable baffle 315 becomes vertical, and the fixed shaft 416 also rotates ninety degrees. At this time, the expansion shaft 403 and the limiting hole 204 are still coaxial, but in opposite directions. The deflection of the movable baffle 315 causes the feeding plate 103 to lose support. Under the action of the torsion spring, the feeding plate 103 also begins to deflect, and the side of the feeding plate 103 without holes coincides with the chip collection frame 301.Afterwards, the flip motor 303 stops rotating, and the chip collection frame 301 begins the fifth stage of displacement: the chip collection frame 301 continues to move away from the feeding frame 202 (the chip collection frame 301 moves closer to the dressing motor 102). Then, the locking teeth 105 engage with the expansion shaft 403 and abut against the synchronization ring 407, pushing the synchronization ring 407, that is, the pull rod 406 moves to the locking slot unit IV 4054. At this time, the flip motor 303 and the feeding motor 206 stop rotating, while the dressing motor 102 starts rotating, causing the grinding wheel 6 to start rotating through the locking teeth 105. As the grinding wheel 6 rotates, the laser dressers 104 on both sides begin to dress it. A small amount of debris is generated at this time, falling onto the side of the feed plate 103 with holes, but no debris accumulates on the feed plate 103. After dressing is complete, the dressing motor 102 stops rotating, the feeding motor 206 continues to rotate, and the chip collection frame 301 begins its sixth stage of displacement: the chip collection frame 301 begins to move away from the dressing motor 102. At this time, the pull rod 406 slides from the locking slot unit IV 4054 to the locking slot unit V 4055, and then slides into the locking slot. In unit VI 4056, because the grinding wheel 6 has lost the support of support plates I 401 and II 402, and the axes of support plates I 401 and II 402 are not parallel to the axis of the expansion shaft 403, the grinding wheel 6 will slip onto the side of the feed plate 103 with the hole; then the chip collection frame 301 begins the seventh stage of displacement: the tilting motor 303 begins to rotate in the opposite direction, at which time the drive shaft 309 begins to slowly rotate 90 degrees, and at the same time the movable baffle 315 also begins to change from a vertical state to a horizontal state. The deflection of baffle 315 lifts the feed plate 103, at which point the feed plate 103 discharges the dressed grinding wheel 6 from the chip collection frame 301. At this point, the side of the feed plate 103 with the hole aligns with the chip collection frame 301. Then, the chip collection frame 301 begins its eighth stage of displacement: the tilting motor 303 continues to rotate, driving the rotating shaft 309 to slowly rotate 90 degrees. Afterward, the expanding shaft 403 returns to its initial position, and the movable baffle 315 also moves vertically downwards in a horizontal position back to its initial position, thus completing one work cycle.
