The production of NdFeB magnet includes cutting process. For thinner NdFeB magnet materials, laser flexible cutting equipment can be used for processing, and the cutting accuracy is higher. During the cutting process, NdFeB magnet is easy to deviate in the device, affecting the accuracy of the processing position.

At the same time, the sliding of the clamping block clamps and fixes the NdFeB body, thereby realizing a control operation to improve the stability of the NdFeB magnet during cutting when the NdFeB is cut by the flexible cutting equipment.

In addition, when collecting the waste generated by the cutting of the NdFeB magnet, in order to maintain the collection volume, the collection box is generally large in size. When the cutting waste falls into the collection box, it collides and splashes with other waste, which is not conducive to the safe use of production equipment by workers. Utility Model Content

[0026] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] See also Figure 1-Figure 4 As shown, a flexible cutting device for processing NdFeB magnets at an oblique angle comprises an equipment support 1, a laser cutting assembly 2 longitudinally slidably mounted on the equipment support 1, and a cylinder 3 fixed on the equipment support 1 for driving the laser cutting assembly 2 to move longitudinally. The flexible cutting device also comprises a processing platform 4 fixed on the outside of the cylinder body of the cylinder 3, a sliding bracket 41 is slidably mounted transversely on the processing platform 4, a clamping frame 42 for clamping NdFeB magnet material is rotatably mounted on the sliding bracket 41, a steering control assembly 43 for controlling the clamping frame 42 to rotate at a fixed angle is mounted on the sliding bracket 41, a square groove is opened in the processing platform 4, the sliding bracket 41 is slidably mounted in the square groove inside the processing platform 4, and a lead screw is rotatably mounted in the square groove on the processing platform 4, the lead screw is connected to the output end of the motor, the lead screw is threadedly assembled with the sliding bracket 41, and the sliding bracket 41 can be controlled to slide transversely through the processing platform 4 through the lead screw thread transmission structure.

[0028] The NdFeB magnet material is arranged between the left and right groups of clamping frames 42, and the sliding bracket 41 is controlled by the screw transmission structure to move horizontally through the processing platform 4. The sliding bracket 41 drives the clamping frame 42 to move horizontally synchronously, so that the clamping frame 42 is clamped on the left and right sides of the NdFeB magnet material, and the quick clamping of the NdFeB magnet material is limited in the cutting device. According to the needs of cutting the NdFeB magnet material, the steering control component 43 is operated to control the clamping frame 42 to rotate at a fixed angle, and the angle of the NdFeB magnet material corresponding to the bottom of the laser cutting component 2 is accurately adjusted to improve the accuracy and qualified rate of cutting the NdFeB magnet material.

[0029] See also Figure 4-Figure 6 As shown, the steering control assembly 43 includes a curved disk 431 rotatably mounted on the sliding bracket 41, the curved disk 431 is fixedly connected to the clamping frame 42, and steering grooves 432 are provided at equal angles on the circumference of the curved disk 431. A servo motor 433 is fixedly mounted on the sliding bracket 41, and a driving disk 434 is connected to the output end of the servo motor 433. A driving rod 435 is eccentrically mounted on the driving disk 434, and the driving rod 435 slides into the steering groove 432 provided on the curved disk 431 when the driving rod 435 rotates in a circle.

[0030] The servo motor 433 is operated to control the driving disk 434 to rotate, and the driving disk 434 drives the driving rod 435 on the side to rotate in a circle. During the circular rotation, the driving rod 435 slides into the steering groove 432 opened on the side of the arc disk 431. The driving rod 435 is embedded in the steering groove 432 and slides, pushing the arc disk 431 to rotate at a fixed angle, and accurately adjusting the steering angle of the clamping frame 42, so as to assist in accurately adjusting the processing angle corresponding to the NdFeB magnet material clamped in the clamping frame 42.

[0031] See also Figure 4-Figure 6 As shown, a locking structure for limiting the rotation angle of the cambered disk 431 is provided between the cambered disk 431 and the driving disk 434 .

[0032] Under the cooperation of the driving disk 434, the driving rod 435, the steering groove 432 and the arc disk 431, the arc disk 431 is controlled to rotate at a certain angle. When the arc disk 431 rotates to a certain angle, the angular position of its steering control can be limited by the locking structure to maintain the stability of the corresponding position of the clamping frame 42 after the steering adjustment.

[0033] See also Figure 4-Figure 6 As shown, the locking structure includes positioning grooves 436 which are arranged at equal angles on the circumference of the arc disk 431, and a limiting cam 437 which is fixed on the driving disk 434. The limiting cam 437 is rotatably engaged with the positioning groove 436. The number of positioning grooves 436 arranged on the circumference is the same as the number of steering grooves 432 arranged on the circumference, and the positions of the positioning grooves 436 and the steering grooves 432 correspond to each other.

[0034] When rotating, the driving disk 434 controls the driving rod 435 to rotate in a circle, and drives the limiting cam 437 to rotate synchronously. When the driving rod 435 rotates in a circle away from the steering groove 432, the limiting cam 437 rotates and engages in the corresponding positioning groove 436. The steering angle of the arc disk 431 is limited by the engaging structure. When the driving rod 435 rotates in a circle and enters the steering groove 432, the limiting cam 437 rotates away from the positioning groove 436, and the arc disk 431 can be driven by the rotating driving rod 435 to rotate at a fixed angle.

[0035] See also Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, a waste material collection box 5 is installed through the processing platform 4, and a rectangular frame 51 is longitudinally slidably installed in the inner wall of the waste material collection box 5. A net bag 52 for receiving and buffering cutting waste is installed on the rectangular frame 51. The net bag 52 is a trapezoidal structure, which can guide the cut waste to slowly move downward into the waste material collection box 5.

[0036] When the cut waste falls into the net bag 52, the net bag 52 has a certain cushioning property, which can reduce the impact force of the falling cut waste, and under the cushioning effect of the net bag 52, the waste can be guided into the waste collection box 5 below, avoiding the cut waste from colliding and splashing with the inner wall of the waste collection box 5 or other waste in the waste collection box 5 during the falling process.

[0037] See also Figure 7 and Figure 8 As shown, a slide groove 53 is provided on the residual material collection box 5, and a lifting frame 54 is slidably assembled in the slide groove 53. The lifting frame 54 is fixedly assembled with the rectangular frame 51. An electric lifting rod 55 is fixedly installed on the outside of the residual material collection box 5, and the lifting end of the electric lifting rod 55 is fixedly assembled with the lifting frame 54.

[0038] The electric lifting rod 55 is operated to push the lifting frame 54 to move up and down. The lifting frame 54 slides upward along the slide groove 53. The lifting frame 54 is fixedly assembled with the rectangular frame 51, and controls the rectangular frame 51 to move up and down synchronously, and adjusts the position of the rectangular frame 51 and the net bag 52 corresponding to the bottom of the clamped NdFeB magnet material.

[0039] See also Figure 7 and Figure 8 As shown, a supporting column 56 for supporting the NdFeB magnet to be processed is installed in the middle of the rectangular frame 51 .

[0040] When the rectangular frame 51 moves upward, the supporting column 56 is controlled to move upward synchronously, so that the supporting column 56 is supported under the NdFeB magnet material to maintain the stability of the NdFeB magnet material during cutting and processing.
