Description

Technical Field

[0001] This utility model belongs to the field of magnetic core production technology, specifically relating to a chamfering device for pressed magnetic cores. Background Technology

[0002] Currently, after pressing, the magnetic core needs to be chamfered. However, existing chamfering devices mostly rely on manual operation for the core process: the magnetic core needs to be manually placed into the processing position and pressed and fixed, which is not only prone to deformation due to uneven clamping force, but also may cause positioning deviation due to hand tremors; during processing, the magnetic core needs to be manually flipped to process the corners at both ends. The equipment needs to be paused when flipping, and repositioning requires repeated calibration, which increases labor intensity and leads to poor consistency of the same batch of magnetic cores due to the randomness of manual operation. Utility Model Content

[0003] This invention addresses the aforementioned problems by providing a chamfering device for pressed magnetic cores.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a powder-pressing magnetic core chamfering device, comprising a worktable, a placement groove on the worktable, a magnetic core placed in the placement groove, an inverted U-shaped frame installed above the worktable, a lifting mechanism installed below the inverted U-shaped frame, a connecting plate three installed below the lifting mechanism, two cylinders four installed below the connecting plate three, racks installed at the piston rod ends of the two cylinders four, the racks meshing with gears, a rotating shaft installed inside the gears, cylinders three installed on the side of the rotating shaft, and arc-shaped clamping parts detachably connected to the piston rod ends of the cylinders three, the arc-shaped clamping parts corresponding to the two cylinders four being arranged opposite to each other, and a chamfering mechanism and a pushing mechanism installed above the worktable.

[0005] Preferably, a connecting plate one is installed below the lifting mechanism, and a connecting plate two is installed below the connecting plate one. Two through holes one are opened on the side of the connecting plate two, and the rack is located in the through hole one.

[0006] Preferably, the lifting mechanism includes multiple cylinders, each cylinder being installed below the inverted U-shaped frame, with the piston rod ends of each cylinder being fixedly connected to the connecting plate and the top of the connecting plate, respectively.

[0007] Preferably, the chamfering mechanism includes a guide rail and a servo motor. The guide rail is mounted above the worktable, and the servo motor is mounted at the end of the guide rail away from the placement slot. The output end of the servo motor is detachably connected to a ball screw, and a slider is fitted on the ball screw. The slider is slidably connected to the guide rail, and a drive motor is mounted on the slider. The output end of the drive motor is detachably connected to a chamfering grinding head.

[0008] Preferably, a collection box is detachably connected to the side of the drive motor, and an air duct is installed and connected to the side of the collection box. A dust suction cover is installed at the end of the air duct, and a suction pump is installed on the air duct.

[0009] Preferably, the pushing mechanism includes a side U-shaped frame and two cylinders, the two cylinders are mounted on the worktable, the placement slot is located between the two cylinders, and the two ends of the side U-shaped frame are detachably connected to the piston rod ends of the two cylinders respectively.

[0010] Preferably, the lifting mechanism is externally connected to a controller, and the cylinder four, cylinder three, chamfering mechanism and pushing mechanism are all communicatively connected to the controller.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: (1) Existing chamfering devices mostly rely on manual placement into the processing position and manual pressing to fix them. However, this utility model uses a cylinder to drive the arc-shaped clamping piece to approach the magnetic core from both sides simultaneously. The arc-shaped clamping piece achieves stable clamping and reduces magnetic core deformation. (2) The extraction pump sucks the debris generated during the chamfering process into the collection box in a timely manner through the air duct and dust hood. It can efficiently capture debris and avoid debris splashing and polluting the environment or being inhaled by the operator. This design not only keeps the workbench clean, but also reduces the wear of debris on other parts of the equipment, extends the service life of the device, and at the same time ensures the health and safety of the operator. (3) After the magnetic core is clamped, it is meshed by rack and gear, so that the magnetic core can quickly switch the processing surface. Compared with traditional manual chamfering or step-by-step processing equipment, the processing cycle of a single magnetic core is greatly shortened and the overall production efficiency is improved.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example 1 The following is in conjunction with the appendix Figure 1-4 To further describe this utility model, a chamfering device for pressed powder magnetic cores, such as... Figures 1-4 As shown, the device includes a workbench 1 with a placement slot for a magnetic core. An inverted U-shaped frame 2 is mounted above the workbench 1, and a lifting mechanism is mounted below the inverted U-shaped frame 2. A connecting plate 3 12 is mounted below the lifting mechanism, and two cylinders 4 13 are mounted below the connecting plate 3 12. A rack 11 is mounted on the piston rod end of each of the two cylinders 4 13, and the rack 11 meshes with a gear 10. A rotating shaft is mounted inside the gear 10, and a cylinder 3 9 is mounted on the side of the rotating shaft. An arc-shaped clamping member 8 is detachably connected to the piston rod end of the cylinder 3 9. The arc-shaped clamping members 8 corresponding to the two cylinders 4 13 are arranged opposite each other. A chamfering mechanism and a pushing mechanism are mounted above the workbench 1.

[0017] like Figures 1-4 As shown, a connecting plate 3 is installed below the lifting mechanism, and a connecting plate 4 is installed below the connecting plate 3. Two through holes are opened on the side of the connecting plate 4, and the rack 11 is located in the through hole.

[0018] The lifting mechanism includes multiple cylinders 5, which are all installed below the inverted U-shaped frame 2. The piston rod ends of the multiple cylinders 5 are fixedly connected to the top of the connecting plate 12 and the connecting plate 3, respectively.

[0019] like Figure 1 and Figure 3As shown, the chamfering mechanism includes a guide rail 14 and a servo motor 16. The guide rail 14 is mounted above the worktable 1, and the servo motor 16 is mounted at the end of the guide rail 14 away from the placement slot. The output end of the servo motor 16 is detachably connected to a ball screw, and a slider 15 is fitted on the ball screw. The slider 15 is slidably connected to the guide rail 14. A drive motor 17 is mounted on the slider 15, and the output end of the drive motor 17 is detachably connected to a chamfering grinding head 21.

[0020] like Figure 3 As shown, a collection box 18 is detachably connected to the side of the drive motor 17. An air duct 19 is installed and connected to the side of the collection box 18. A dust suction hood 20 is installed at the end of the air duct 19. An extraction pump is installed on the air duct 19.

[0021] like Figure 1 and Figure 4 As shown, the pushing mechanism includes a side U-shaped frame 6 and two cylinders 7. The two cylinders 7 are mounted on the worktable 1, and the placement slot is located between the two cylinders 7. The two ends of the side U-shaped frame 6 are detachably connected to the piston rod ends of the two cylinders 7 respectively.

[0022] In this invention, there is a certain distance between connecting plate 3 and connecting plate 12, which allows the magnetic core to be processed to rotate 180° in the axial direction.

[0023] In this invention, the chamfering grinding head 21 and the dust collection hood 20 are separated by a certain distance, and the dust collection end of the dust collection hood 20 faces the chamfering grinding head 21.

[0024] In this utility model, the lifting mechanism is externally connected to a controller, and cylinder 13, cylinder 9, the chamfering mechanism and the pushing mechanism are all connected to the controller in communication.

[0025] In this utility model, cylinder 5, servo motor 16, drive motor 17, extraction pump, cylinder 7, cylinder 13 and cylinder 9 are all connected to the controller for communication.

[0026] In this invention, multiple cylinders 5 can be synchronously controlled by a controller, two cylinders 7 can be synchronously controlled by a controller, two cylinders 13 can be synchronously controlled by a controller, and the cylinders 9 corresponding to the two cylinders 13 can be synchronously controlled by a controller (the above control methods are existing technologies).

[0027] The working principle of this utility model is as follows: The operator places the pressed powder magnetic core to be processed into the placement slot of the workbench 1, opens cylinder 5, and the piston rod of cylinder 5 extends downward, driving connecting plate 3 and connecting plate 4 to descend synchronously. As connecting plate 3 descends, connecting plate 4 also moves downward until the arc-shaped clamping member 8 is lowered to the height corresponding to the magnetic core in the placement slot. Then, cylinder 5 is closed and cylinder 9 is opened, the piston rod of cylinder 9 extends, causing the two oppositely arranged arc-shaped clamping members 8 to approach the magnetic core and complete clamping and fixing. Cylinder 9 is closed and cylinder 5 is opened, causing the magnetic core to move upward to a suitable height. Cylinder 5 is closed and cylinder 9 is opened. Cylinder 413's piston rod extends and retracts, causing rack 11 to move within through hole 1. Rack 11 meshes with gear 10, driving the rotating shaft to rotate cylinder 39 and the held magnetic core 90°. Cylinder 413 is then closed, and servo motor 16 is activated. Its output drives ball screw 1 to rotate, and slider 15 slides along guide rail 14 towards the magnetic core until chamfering head 21 reaches the chamfering position on the magnetic core. Drive motor 17 then starts, driving chamfering head 21 to rotate at high speed, chamfering one end of the magnetic core. During this process, extraction pump operates synchronously, sucking up and collecting the debris generated during chamfering through dust hood 20 and air duct 19. Box 18 ensures a clean processing environment. After chamfering one end of the magnetic core, the chamfering grinding head 21 returns to its initial position. The extraction pump, drive motor 17, and servo motor 16 are shut down. Cylinder 4 13 is activated. The piston rod of cylinder 4 13 extends and retracts, causing rack 11 to move within through hole 1. Rack 11 meshes with gear 10, causing the rotating shaft to rotate cylinder 3 9 and the held magnetic core 180°. After rotation, cylinder 4 13 is shut down. The chamfering mechanism then chamfers the other end of the magnetic core according to the above process. Cylinder 4 13 is activated again, and the piston rod of cylinder 4 13 extends and retracts, causing rack 11 to move within through hole 1. Rack 11... Engaging with gear 10, the rotating shaft drives cylinder 3 9 and the clamped magnetic core to rotate 90°. Cylinder 4 13 is closed, and cylinder 1 5 is opened, causing the processed magnetic core to move down into the placement slot. Cylinder 1 5 is closed, and cylinder 3 9 is opened, causing the two opposing arc-shaped clamping parts 8 to move towards the magnetic core. Cylinder 3 9 is closed, and cylinder 1 5 is opened, causing cylinder 1 5 to drive connecting plate 1 3 back to its initial position. The piston rod of cylinder 2 7 is opened, causing the side U-shaped frame 6 to move towards the magnetic core, pushing the processed magnetic core out of the placement slot, thus achieving automatic unloading. After the unloading is completed, each mechanism is reset under the control of the controller, waiting for the next magnetic core processing cycle.

[0028] In this invention, the above processing procedure can be adjusted according to the on-site conditions.

[0029] In this invention, the controller is capable of automatic control.
