Description

Technical Field

[0001] The present application relates to the technical field of NdFeB processing, and in particular to a NdFeB workpiece processing and polishing device. Background Art

[0002] NdFeB grinding equipment is specialized equipment used to treat the surface of NdFeB magnetic materials. NdFeB is a very important permanent magnet material with an extremely high magnetic energy product and a wide range of applications, such as motors, sensors, and speakers. During the production process, NdFeB materials are often polished to achieve specific dimensional accuracy and surface quality requirements.

[0003] Existing NdFeB workpiece processing and grinding equipment typically only operates on one side of the workpiece. After grinding that side, the workpiece needs to be flipped or the angle adjusted to allow further processing of the remaining unprocessed surface. However, in actual operation, the workpiece is tightly fixed by the clamping structure, and the high temperature generated during the grinding process is not dissipated in time, resulting in high surface temperatures of the NdFeB workpiece after grinding. This not only increases the risk of burns to operators when replacing or removing the workpiece, but also reduces overall work efficiency.

[0004] Furthermore, traditional equipment has limitations in achieving workpiece flipping and positioning adjustments. Manual intervention or even complete disassembly of the clamping device is often required to complete workpiece rotation or angle adjustment. This not only increases labor intensity but can also affect workpiece machining accuracy due to improper operation. Furthermore, slight deformation or adsorption between the workpiece and the clamping components at high temperatures can further complicate workpiece disassembly and affect production continuity.

A displacement sensor is installed on the top of the limit plate 410, so that the workpiece can be ground in conjunction with the grinding wheel 311.

One end of the third threaded rod 412 is movably connected to a clamping plate 413. The bottom of the clamping plate 413 is slidably connected to the top of the limit plate 410. The clamping plate 413 is L-shaped and can clamp NdFeB workpieces of different lengths for grinding corners. The front and rear sides of the bottom of the protective box 47 are fixedly connected to the moving frame 414. The output end of the electric push rod 45 is fixedly connected to the connecting rod 415. The surface of the connecting rod 415 is in contact with the inner side of the moving frame 414. The front and rear sides of the connecting rod 415 are fixedly connected to the connecting plate 416. The bottom of the connecting plate 416 extends to the inner cavity of the slider 43 and is fixedly connected to the tooth plate 417. The top of the slider 43 is provided with a fixed cavity for facilitating the movement of the connecting plate 416 and the receiving plate 422. Figure 6 As shown, the bottom of the tooth plate 417 is slidably connected to the bottom of the inner cavity of the slider 43, and an anti-collision cavity is opened on the right side of the slider 43 to avoid the problem of movement interference of the slider 43 during the movement of the tooth plate 417. The front and rear sides of the round rod 418 are fixedly connected with gears 419 that mesh with the tooth plate 417, and the front and rear sides of the slider 43 are fixedly connected with telescopic rods 420.

[0041] like Figure 5-Figure 13 As shown, the front and rear sides of the receiving plate 422 are fixedly connected to the block 421, the output end of the telescopic rod 420 is fixedly connected to the bottom of the block 421, the receiving plate 422 and the clamping plate 413 cooperate with each other, and the left and right sides of the slider 43 are fixedly connected to the cleaning plate 425, the inner side of the cleaning plate 425 contacts the outer surface of the slide rail 42, and the inner side of the cleaning plate 425 is assembled with soft cleaning materials such as a brush, so as to facilitate cleaning impurities from the surface of the slide rail 42 to avoid damage to the surface of the slide rail 42, and the front and rear sides of the slider 43 are provided with discharge holes, so as to facilitate cleaning waste retained in the inner cavity of the slider 43, and a suction fan 426 is installed on the top of the processing table 1, the feed port of the suction fan 426 is connected to the inner cavity of the grinding box 41, and the discharge port of the suction fan 426 is connected to the inner cavity of the sedimentation box 2, and the feed port and the discharge port are both connected by a hose.

[0042] Specifically, the user places the NdFeB workpiece on the limiting plate 410 and rotates the third threaded rod 412 to engage the threaded sleeve 411, thereby pushing the clamping plate 413 to firmly clamp the NdFeB workpiece of different shapes. After clamping is completed, the slider 43 is pushed to move into the polishing box 41.

[0043] Then, the motor 36 is started, and the motor 36 drives the rotating rod 310 and the pulley 312 to rotate. The rotating rod 310 drives the grinding wheel 311 to rotate, and the edges and corners of the NdFeB workpiece are ground.

[0044] When the height of the grinding wheel 311 needs to be adjusted to accommodate workpieces of different heights, the second threaded rod 34 can be manually rotated. The second threaded rod 34 uses the principle of thread transmission to drive the threaded plate 35 up and down, thereby driving the guide plate 38, motor 36, and grinding wheel 311 to achieve vertical adjustment, thereby accurately positioning the grinding height.

[0045] Furthermore, the grinding wheel 311 can be adjusted in the front-to-back direction to facilitate edge grinding of wider NdFeB workpieces. Rotating the first threaded rod 32 causes the positioning frame 33 and the threaded plate 35 to move synchronously via the threaded drive, thereby adjusting the position of the grinding wheel 311 in the front-to-back direction.

[0046] After chamfering one side of the NdFeB workpiece, the electric push rod 45 is activated, pushing the connecting rod 415 left and right. The connecting rod 415 then drives the moving frame 414, causing the protective box 47 to swing around the connection point of the positioning plate 46. The protective box 47 causes the limiting plate 410 and the clamped NdFeB workpiece to tilt together, facilitating subsequent rotation operations.

[0047] Then the motor 48 is started, the motor 48 drives the operating rod 49 to rotate, and the operating rod 49 drives the limit plate 410 to rotate, thereby driving the clamped NdFeB workpiece to rotate as a whole, and the unpolished side is replaced for further chamfering processing.

[0048] After chamfering is complete, the electric push rod 45 is activated again, pushing the connecting rod 415 to the left, causing the protective box 47 to tilt the clamping plate 413 and the workpiece to the right. Simultaneously, the connecting rod 415 pushes the connecting plate 416, which in turn moves the toothed plate 417. During this movement, the toothed plate 417 engages with the gear 419, causing it to rotate and drive the round rod 418.

[0049] The round rod 418 drives the guide frame 424 to rotate upward, and the guide frame 424 pushes the short rod 423 and the receiving plate 422 upward. At this time, the clamping device can be released, allowing the polished NdFeB workpiece to slide onto the receiving plate 422 for temporary storage, effectively avoiding the problem of difficult removal due to overheating of the workpiece.

[0050] Specifically, the working principle of this NdFeB workpiece processing and grinding equipment is: the user places the NdFeB workpiece into the feeding assembly 4 for clamping, and then sends the NdFeB workpiece into the grinding box 41 through the feeding assembly 4 for grinding. At this time, the grinding assembly 3 is started to grind the edges and corners of the NdFeB workpiece. When one side of the corner is ground, the feeding assembly 4 is started to flip the NdFeB workpiece, so that both sides and multiple sides of the NdFeB workpiece are ground. After grinding is completed, the grinding completed NdFeB workpiece is placed into the receiving plate 422 through the feeding assembly 4 for cooling and placement. At this time, the user can continue to process the NdFeB workpiece through the feeding assembly 4, so as to facilitate the grinding of the NdFeB workpiece and facilitate use.
