[0029] Reference Figure 1 and Figure 2 and Figure 3The present invention provides an embodiment of a high-precision cutting device for magnet blanks, comprising a processing table 1, which serves as the basic supporting structure of the entire device, and can maintain the stability of the device, thereby ensuring the accuracy of cutting. A moving mechanism 3 is installed on the top of the processing table 1, and a moving seat 4 is installed on the moving mechanism 3. The moving mechanism 3 is a prior art, which can drive the moving seat 4 to move horizontally or vertically after starting. The moving seat 4 is fixedly connected with a cutting assembly, and the cutting position is adjusted under the operation of the moving mechanism 3. The cutting assembly is used to cut the magnet. A slide 7 is slidably connected to the front side of the top of the processing table 1, and a motor 2 8 is installed on the top of the slide 7. The slide 7 provides an installation base for the motor 2 8, and the motor 2 8 serves as a driving source. The output end of the motor 2 8 is fixedly connected with a gear 9, which can drive it to rotate during operation. The outside of the gear 9 is connected to a cleaning brush 13 through a rotating shaft. The inside of the cleaning brush 13 is provided with an electromagnet, which can generate magnetism after being energized. When cleaning the surface of the processing table 1, magnetic debris in the gap is adsorbed, thereby improving the cleaning effect. A rack plate 6 is fixedly connected to one side close to the gear 9. The surface of the rack plate 6 is meshed with the gear 9. After the rack plate 6 is meshed with the gear 9, the rack plate 6 will move along the gear 9 when rotating, thereby driving the slide 7 to slide. A guide assembly is provided on the top rear side of the processing table 1. The guide assembly is used to maintain the horizontal movement of the cleaning brush 13. Clamping assemblies are provided on the front and back sides of the top of the processing table 1. The clamping assembly is used to fix the magnet. The guide assembly includes two fixed blocks 10. The two fixed blocks 10 are fixedly connected to the On the rear side of the top, a slide bar 11 is fixedly connected between the two fixed blocks 10. The slide bar 11 has a guiding function to ensure that the cleaning brush 13 keeps moving horizontally. The outside of the slide bar 11 is slidably connected to the slider 12. The outside of the slider 12 is fixedly connected to one end of the cleaning brush 13. A strip hole 16 is provided on the top right side of the processing table 1. Below the strip hole 16, a collection box 2 is slidably connected to the inside of the processing table 1. The strip hole 16 makes it easy to sweep the cleaned debris into the collection box 2 below, thereby realizing the collection of debris and facilitating unified processing.
[0030] Specifically, when cutting the magnet blank, the position of the movable seat 4 can be adjusted by the moving mechanism 3, so that the cutting assembly can cut the magnet blank horizontally or vertically, which improves the flexibility of the device. Then the operation of the cutting assembly realizes the cutting operation, and the magnet blank can be cut into the required size and size, which is convenient for subsequent processing. After the cutting is completed, a large amount of debris will be generated. It can be started by starting the motor 2 8. The motor 2 8 can drive the gear 9 to rotate as a driving source. Since the gear 9 is engaged with the rack plate 6, the rack plate 6 will move along the gear 9 when rotating, and at the same time make the slide 7 move along the slide opened on the top of the processing table 1. The groove moves. At this time, under the connection of the cleaning brush 13, the slider 12 in the guide assembly will slide along the slide rod 11 and cooperate with the slide seat 7, so that the cleaning brush 13 keeps moving horizontally, and when moving, the magnetic debris generated after cutting on the top of the processing table 1 is swept away, reducing the workload of workers, improving the cleaning efficiency, and avoiding the debris affecting the cutting accuracy. At the same time, the cleaned debris will fall from the strip hole 16 into the collection box 2 below, thereby completing the collection of the debris and facilitating unified processing. At the same time, when the cleaning brush 13 moves, the electromagnet inside it can be energized to generate magnetic force to absorb the debris that is difficult to clean in the gap, thereby improving the cleaning effect.
[0031] Reference Figure 4 and Figure 5 The cutting assembly includes a motor 5, which is installed on the outside of the mobile seat 4. As the power source of the cutting assembly, the motor 5 can provide the power required for cutting, and is fixed on the outside of the mobile seat 4 so that it can remain stable during operation. The output end of the motor 5 is fixedly connected to the mounting seat 17, and the outside of the mounting seat 17 is fixed with a fixing ring 18 by snapping. The outside of the fixing ring 18 is fixedly connected with a blade 19. The blade 19 is fixed to the mounting seat 17 by the cooperation of the fixing ring 18 and the snap assembly. Two card slots 20 are provided on the inner side of the fixing ring 18. The mounting seat Two limiting grooves 21 are provided inside 17, and a spring 22 is fixedly connected inside the limiting groove 21. The spring 22 is fixed by the limiting groove 21 so that it remains stable during rebound and contraction. One end of the spring 22 is fixedly connected to a moving block 23, one end of the moving block 23 is fixedly connected to a push rod 24, and the other end of the moving block 23 is fixedly connected to a clamping block 25. The moving block 23 is slidably connected to the inside of the limiting groove 21, one end of the push rod 24 extends to the outside of the mounting seat 17, and one end of the clamping block 25 passes through the outer wall of the mounting seat 17 and engages with the clamping groove 20 on the adjacent side.
[0032] Specifically, when the blade 19 is disassembled, the push rods 24 on both sides of the mounting seat 17 can be pressed. The push rods 24 can play a role in force transmission, thereby pushing the moving block 23 to move inside the limiting groove 21. The limiting groove 21 limits the movement of the moving block 23, so that the structure remains stable, and then the moving block 23 puts pressure on the spring 22 to make it contract. At the same time, the moving block 23 will drive the clamping block 25 to disengage from the clamping groove 20, and then the blade 19 can be separated from the mounting seat 17, thereby realizing rapid disassembly of the blade 19, facilitating rapid replacement operations, reducing downtime, and improving production efficiency. The spring 22 can release the elastic force when installing the blade 19 to push the moving block 23 to reset, so that the clamping block 25 is inserted into the clamping groove 20 to complete the engagement, thereby achieving fixation of the fixing ring 18, and then completing the rapid installation of the blade 19.
[0033] Reference Figure 2 The clamping assembly includes multiple hydraulic rods 14, which are fixedly connected to the inner side of the top of the processing table 1. The hydraulic rods 14 are fixed to the processing table 1 so that the hydraulic rods 14 remain stable during operation. The output ends of the multiple hydraulic rods 14 are fixedly connected with a clamping plate 15, which is pushed to move by the hydraulic rods 14 to fix the magnet blank, thereby maintaining stability during cutting and improving the cutting accuracy.
[0034] Specifically, the operation of the hydraulic rod 14 can push the clamping plate 15 to move, and under the clamping of the clamping plates 15 on both sides, the magnet blank can be fixed on the top of the processing table 1, so that it will not move during cutting, ensuring the cutting accuracy.
[0035] Working principle: When using this device, first place the magnetic blank to be cut on the processing table 1, and push the clamping plate 15 to move by the operation of the hydraulic rod 14, so as to fix the magnetic blank. Then, the position of the movable seat 4 can be adjusted by the operation of the moving mechanism 3, so that the cutting assembly moves, and the blade 19 is driven by the motor 1 5 to rotate to achieve the cutting of the magnetic blank. After the cutting is completed, the motor 2 8 can be started to drive the gear 9 to rotate, and then the gear 9 is engaged with the rack plate 6, so that the slide 7 moves along the slide groove opened on the top of the processing table 1. At the same time, with the cooperation of the guide component, the cleaning brush 13 is driven to move horizontally, so as to sweep away the magnetic debris generated after cutting on the top of the processing table 1, and drop it from the strip hole 16 into the collection box 2 below, completing the collection of the debris for unified treatment. At the same time, when the cleaning brush 13 moves, the electromagnet inside it can be energized to generate magnetic force to absorb the debris that is difficult to clean in the gap, thereby improving the cleaning effect.
[0036] Secondly, when replacing the blade 19, the push rods 24 on both sides of the mounting seat 17 can be pressed so that the push rods 24 push the moving block 23 to move inside the limit groove 21, and then pressure is applied to the spring 22 to shrink it. At the same time, the moving block 23 will drive the card block 25 to disengage from the card slot 20. At this time, the blade 19 can be separated from the mounting seat 17, thereby realizing rapid disassembly of the blade 19, facilitating rapid replacement operations, reducing downtime, and improving production efficiency.
[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
